The present invention relates to medical access devices and more particularly to break-away connectors for medical tubing.
Various medical tubes are used in treatment of patients, such as intravenous catheters, feeding tubes, dialysis tubes, enteral feeding, foley catheters. It is appreciated that these medical tubes are generally flexible, thus allowing the patient a range of movement.
For instance, medicaments may be administered to a patient through an IV line, which is connected to a needle, which is in turn fixed to an injection site. Additional example is a catheter which is inserted into a desired treatment location within the body of the patient.
During movement of the patient undergoing treatment, the medical tubes are subject to certain tensile forces that may cause dislocation of the catheter or of the needle. Additionally, certain tensile forces, greater than a pre-determined threshold, may cause spillage of the medicaments being administered to the patient or the patient's body fluids and thus expose the patient to a risk of infection.
The present invention seeks to provide an improved break-away connector.

A fluid flow passage 430 is defined by the inner volume of the sealing element 420 and the inner volume of the male luer portion 414, however fluid flow is not permitted through the fluid flow passage 430 when the slit 426 is closed and the second selectably openable end 424 provides a swabbable surface that may be cleaned by the physician in order to prevent contamination.
It is noted that instead of the male luer portion 414, a female luer portion or tube connection element may be utilized.
It is noted that the sealing element 420 is biased to its normally closed position once a compression force exerted thereon is removed.
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 100, constructed and operative in accordance with an embodiment of the present invention.

It is a particular feature of an embodiment of the present invention that upon connection of both the first and the second luer-actuated valve assemblies 400 and 402 to the breakaway intra-medical tubing connector assembly 100, a fluid flow passage is established between two medical tubes, each of which is adapted to be connected to the respective male luer portion 414 of the first and second luer-actuated valve assemblies 400 and 402.
It is a further particular feature of an embodiment of the present invention that the inner diameter of the fluid flow passage provided between the first and second luer-actuated valve assemblies 400 and 402 is substantially the same as the diameter of the thoroughgoing bore 260 of the connector element 104.
Specifically, it is seen in
It is appreciated that the first and second medical tubes are adapted to be positioned in a certain treatment area within the patient's body, thus dis-location of one of the medical tubes from its desired position may require replacement of the entire medical set in absence of a connector such as the breakaway intra-medical tubing connector assembly 100 constructed and operative in accordance with an embodiment of the present invention.
It is noted that compression forces exerted on both luer-actuated valve assemblies 400 and 402 by the connector element 104 are enabled by the fact that both luer-actuated valve assemblies 400 and 402 are held in place relative to the breakaway intra-medical tubing connector assembly 100 due to snap-fit connection between snap-fit fittings 120 and the connector body 102.
The breakaway intra-medical tubing connector assembly 100 is disposable in case the respective snap connections 140 and 330 provided between the first snap-fit fitting 120 and the connector body 102 and snap connections 170 and 330 provided between the second snap-fit fitting 120 and the connector body 102 are deformable, such that additional engagement of one of the snap-fit fittings 120 with the connector body 102 is not intended after first use.
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 100, constructed and operative in accordance with an embodiment of the present invention.
It is noted that both the first and the second luer-actuated valve assemblies 400 and 402 may be freely rotated about axis 101 along with the respective snap-fit fittings 120 while being engaged with the intra-medical tubing connector assembly 100, without causing disengagement of the snap-fit fittings 120 with luer-actuated valve assemblies 400 and 402 therefrom.
It is further noted that upon connection of one of the luer actuated valve assemblies 400 and 402, the connector element 104 is axially slidably moveable and thus provides for both of the luer-actuated valve assemblies 400 and 402 to remain sealed up until both of the luer-actuated valve assemblies 400 and 402 are connected to their respective snap-fit fittings 120, which provides for opening of the sealing members 420 of both luer-actuated valve assemblies 400 and 402.

It is noted that one of the luer actuated valve assemblies 400 and 402 may be disconnected upon application of a different tensile force magnitude. In case that snap connection 170 extends radially outwardly to a lesser extent in comparison with snap connection 140, then the second luer actuated valve assembly 402 is intended to be disconnected first from the connector body 102. Alternatively, the connector body 102 can be designed differently such that the first luer actuated valve assembly 400 is disconnected first, in case snap connection 140 extends radially outwardly to a lesser extent in comparison with snap connection 170.

It is a particular feature of an embodiment of the present invention that upon disconnection of the second luer-actuated valve assembly 402 from the breakaway intra-medical tubing connector assembly 100 and according to this particular embodiment upon disconnection of one of the snap-fit fittings 120 along with one of the luer-actuated valve assemblies 400 or 402 from the connector body 102, both of the luer-actuated valve assemblies are automatically bidirectionally closed, thus preventing fluid flow passage from each of the two medical tubes. Upon discarding of the breakaway intra-medical tubing connector assembly 100 along with the two snap-fit fittings 120, two sealed and swabbale luer-actuated valve assemblies 400 and 402 are provided, which obviate the need to replace the entire medical set, and only requires replacement of the breakaway intra-medical tubing connector assembly 100.
In this third operative orientation, the first tubular portion 280 of the connector element 104 is fully surrounded by the internally threaded portion 310 of the first snap-fit fitting 120 and the connector body 102, such that the connector element 104 does not protrude outwardly from the second open end 302 of the first snap-fit fitting 120. The second tubular portion 282 of the connector element 104 protrudes outwardly from the connector body 102.
Upon disconnection of one of the snap fit fittings 120 along with the second luer-actuated valve assembly 402, the connector element 104 is displaced in the direction indicated by arrow 440, preferably up to engagement of first annular protrusion 270 of the connector element 104 with annular protrusion 212 of the connector body 102 to prevent the connector element falling out from the breakaway intra-medical tubing connector assembly 100.
The first snap-fit fitting 120 can be threadably disengaged from the first and second luer-actuated valve assemblies 400 and 402, thus leaving the luer-actuated valve assemblies 400 and 402 along with the medical tubes associated therewith within the desired treatment location. Following disconnection of the snap-fit fittings 120 from the first and second luer-actuated valve assemblies 400 and 402, the valve assemblies are swabbable and can be cleaned by the user.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 100, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 400 and 402 remains in its position within the treatment site and the luer-actuated valve assemblies 400 and 402 are safely sealed once one of the luer-actuated valve assemblies 400 and 402 is disconnected from the breakaway intra-medical tubing connector assembly 100. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 400 and 402 and the ability to clean the exterior surface of the sealing element 420.
It is noted that alternatively disconnection of one of the luer-actuated valve assemblies 400 and 402 from the breakaway intra-medical tubing connector assembly 100 may be intentional in order to provide the physician with access point to the IV line. Once one of the luer-actuated valve assemblies 400 and 402 is exposed, it may be used for administering medicament into the treatment site within the patient body or alternatively for withdrawing a blood sample from the patient's body.
It is a particular feature of an embodiment of the present invention that the breakaway intra-medical tubing connector assembly 100 associated with medical connectors, such as luer-actuated valve assemblies 400 and 402 enables both safe unintentional disconnection of one of the luer-actuated valve assemblies and provides access point to the IV line through the exposed sealing element 420 when one of the luer-actuated valve assemblies 400 and 402 is intentionally disconnected.

It is appreciated that the first and second luer-actuated valve assemblies 500 and 502 are commercially available from various manufacturers, such as ICU Medical. It is noted that both first and second luer-actuated valve assemblies 500 and 502 are preferably identical. Alternatively, two different first and second luer-actuated valve assemblies 500 and 502 can be used with the breakaway intra-medical tubing connector assembly 100.
Both luer-actuated valve assemblies 500 and 502 generally extend along longitudinal axis 101 and generally include a housing 510 having a female luer portion 512 and a male luer portion 514 on an opposite end of the housing 510. The female luer portion 512 has an externally threaded portion 516 and an opening 518. A compressible sealing element 520 is disposed within the housing 510. The compressible sealing element 520 has a first open end 522 and a second selectably openable end 524, including a selectively openable slit 526. The selectably openable end 524 of the sealing element 520 is disposed across the opening 518 of the female luer portion 512 in its normally closed operative orientation and thus is adapted to sealingly close the opening 518 when the sealing element 520 is not compressed. It is noted that the sealing element 520 is biased to its normally closed operative orientation when no stress is applied thereupon. A rigid spike 527 is disposed within the sealing element 520. The rigid spike 527 preferably is hollow and defines an inner volume 528 and an opening 529, which is configured to communicate therewith. A fluid flow passage 530 is defined by the inner volume 528 of the rigid spike 527 and the inner volume of the male luer portion 514, however fluid flow is not permitted through the fluid flow passage 530 when the slit 526 is closed and the second selectably openable end 524 provides a swabbable surface that may be cleaned by the physician in order to prevent contamination.
It is noted that instead of the male luer portion 514, a female luer portion or tube connection element may be utilized.

Specifically, it is seen that the compressible sealing element 616 is snugly fitted between the male luer portion 614 and the cover element 615. The sealing element 616 is seated such that the open end 617 thereof engages the second shoulder 650 of the male luer portion 614 and the closed second end 618 is generally aligned with end surface 668 of the cover element 615. The sealing element 616 extends at least through the thoroughgoing bore 672 of the cover element 615 and partially through the inner volume of the cylindrical second end 628 of the male luer portion 614.
The cover element 615 is mounted onto the male luer portion 614 such that forwardly facing surface 666 of the annular flange 664 of the cover element 615 engages an edge of second end 628 of the male luer portion 614.

It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 600, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 613 and 402 remains in its position within the treatment site and the luer-actuated valve assemblies 613 and 402 are safely sealed once one of the luer-actuated valve assemblies 613 and 402 is disconnected from the breakaway intra-medical tubing connector assembly 600. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 613 and 402.
It is noted that alternatively disconnection of the second luer-actuated valve assembly 402 from the breakaway intra-medical tubing connector assembly 600 may be intentional in order to provide the physician with access point to the IV line. Once the second luer-actuated valve assembly 402 is exposed, it may be used for administering medicament into the treatment site within the patient body or alternatively for withdrawing a blood sample from the patient's body.
It is a particular feature of an embodiment of the present invention that the breakaway intra-medical tubing connector assembly 600 associated with medical connectors, such as luer-actuated valve assemblies 613 and 402 enables both safe unintentional disconnection of one of the luer-actuated valve assemblies and provides access point to the IV line through the exposed sealing element 420 when the second luer-actuated valve assembly 402 is intentionally disconnected.

The connector body 802 is an integrally made cylindrical hollow element arranged along longitudinal axis 801, and preferably made of plastic, such as Polypropylene, Polycarbonate or Polyethylene. The connector body 802 has first open end 810 and second open end 812, as mentioned hereinabove. The connector body 802 has an outer surface 830 and an inner surface 832. A snap protrusion 838 is formed adjacent the second end 812 of the connector body 802 and extends radially outwardly from the outer surface 830 and forms a rearwardly facing shoulder 840 with respect to the outer surface 830 of the connector body 802.

It is a particular feature of an embodiment of the present invention that upon connection of both the first and the second luer-actuated valve assemblies 400 and 502 to the breakaway intra-medical tubing connector assembly 800, a fluid flow passage is established between two medical tubes, each of which is adapted to be connected to the respective male luer portion 414 and 514 of the first and second luer-actuated valve assemblies 400 and 502.
It is a further particular feature of an embodiment of the present invention that the inner diameter of the fluid flow passage provided between the first and second luer-actuated valve assemblies 400 and 502 is substantially the same as the diameter of the thoroughgoing bore 260 of the connector element 104.
Specifically, it is seen in
It is appreciated that the first and second medical tubes are adapted to be positioned in a certain treatment area within the patient's body, thus dis-location of one of the medical tubes from its desired position may require replacement of the entire medical set in absence of a connector such as the breakaway intra-medical tubing connector assembly 800 constructed and operative in accordance with an embodiment of the present invention.
It is noted that compression forces exerted on both luer-actuated valve assemblies 400 and 502 by the connector element 104 are enabled by the fact that the first luer-actuated valve assembly 400 is held in place relative to the breakaway intra-medical tubing connector assembly 800 due to snap-fit connection between snap-fit fitting 806 and the connector body 802 and the second luer-actuated valve assembly 502 is held in place relative to the breakaway intra-medical tubing connector assembly 800 due to threadable connection thereof with the connector body 802.
The breakaway intra-medical tubing connector assembly 800 is preferably disposable in case the snap protrusion 838 provided between the snap-fit fitting 806 and the connector body 802 is deformable, such that additional engagement of the snap-fit fitting 806 with the connector body 802 is not intended after first use.
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 800, constructed and operative in accordance with an embodiment of the present invention.
It is noted that the first luer-actuated valve assembly 400 may be freely rotated about axis 801 along with the respective snap-fit fitting 806 while being engaged with the intra-medical tubing connector assembly 800, without causing disengagement of the snap-fit fitting 806 with luer-actuated valve assembly 400 therefrom.
It is further noted that upon connection of one of the luer actuated valve assemblies 400 and 502, the connector element 104 is axially slidably moveable and thus provides for both of the luer-actuated valve assemblies 400 and 502 to remain sealed up until luer-actuated valve assembly 502 is connected to the connector body 802 and the luer actuated valve assembly 400 is connected to the snap-fit fitting 806, which provides for opening of the sealing members 420 and 520 of both luer-actuated valve assemblies 400 and 502 respectively.

In this third operative orientation, the first tubular portion 280 of the connector element 104 protrudes outwardly from the connector body 802, to a longitudinal extent provided by the fact that the second annular protrusion 272 of connector element 104 abuts the annular protrusion 854 of the connector body 802. The second tubular portion 282 of the connector element 104 is fully surrounded by the connector body 802.
The snap-fit fitting 806 can be threadably disengaged from the first luer-actuated valve assembly 400 and the second luer-actuated valve assembly 502 can be threadably disengaged from the connector body 802, thus leaving the luer-actuated valve assemblies 400 and 502 along with the medical tubes associated therewith within the desired treatment location.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 800, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 400 and 502 remains in its position within the treatment site and the luer-actuated valve assemblies 400 and 502 are safely sealed once one of the luer-actuated valve assemblies 400 and 502 is disconnected from the breakaway intra-medical tubing connector assembly 800.

Sleeve 1002 preferably includes a central hub 1010 having two longitudinally extending arms 1012 extending rearwardly from the circumference of central hub 1010 and are mutually diametrically opposed to each other. A pair of first snap fingers 1020 extend longitudinally rearwardly from the circumference of the central hub 1010 and generally disposed between and radially spaced from arms 1012. The first snap fingers 1020 extend along a portion of the longitudinal extent of the arms 1012.
A pair of second snap fingers 1022 extend longitudinally forwardly from each of the arms 1012. Guiding portions 1024 extend longitudinally forwardly from the circumference of the central hub 1010, disposed forwardly of first snap fingers 1020 and radially spaced from second snap fingers 1022.
First snap fingers 1020 each include a radially inwardly extending snap portion 1030 at its rearward end. Snap portion 1030 includes a rearwardly facing surface 1032, a forwardly tapered surface 1034 and a forwardly facing shoulder 1036.
Second snap fingers 1022 each include a snap portion 1040 at its forward end. Snap portion 1040 includes a forwardly facing surface 1042, a rearwardly tapered surface 1044 and a rearwardly facing shoulder 1046.
Guiding portions 1024 each include a radially inwardly directed protrusion 1050.
A thoroughgoing bore 1052 extends along longitudinal axis 1003 through the connector body 1002, including a generally circular bore portion 1054 located at the region of hub 1010 between second snap fingers 1022 and arms 1012.
It is noted that two pairs of first snap fingers 1020 are radially disposed and diametrically opposite to each other, forming an opening between the pairs of first snap fingers 1020. Two pairs of second snap fingers 1022 are radially disposed and diametrically opposite to each other, forming an opening between the pairs of second snap fingers 1022. It is noted that each pair of first snap fingers 1020 is radially disposed between two pairs of second snap fingers 1022. The two pairs of first snap fingers 1020 extend in a first longitudinal direction and the two pairs of second snap fingers 1022 extend in a second longitudinal direction, the first and the second longitudinal directions being opposite to each other.
It is noted that the two pairs of first snap fingers 1020 are resiliently deformable relative to each other due to the fact they are radially spaced from each other, thus allowing radial deformation of the first snap fingers 1020 upon exertion of radial force thereon. The two pairs of second snap fingers 1022 are also resiliently deformable relative to each other due to the fact they are radially spaced from each other, thus allowing radial deformation of the second snap fingers 1022 upon exertion of radial force thereon.

It is appreciated that the first luer-actuated valve assembly 1100 is a female luer-actuated valve assembly, which is either similar to or commercially available from various manufacturers, such as Haemopharm, Halkey-Roberts, Paolo Gobbi Frattini S.r.l.
The first luer-actuated valve assembly 1000 generally extend along longitudinal axis 1003 and generally includes a housing 1110 having a female luer portion 1112 and a male luer portion 1114 on an opposite end of the housing 1110 and a forwardly facing shoulder surface 1115 formed therebetween. The female luer portion 1112 has an externally threaded portion 1116 and an opening 1118. A compressible sealing element 1120 is disposed within the housing 1110. The compressible sealing element 1120 has a first open end 1122 and a second selectably openable end 1124, including a selectively openable slit 1126. The selectably openable end 1124 of the sealing element 1120 is disposed across the opening 1118 of the female luer portion 1112 in its normally closed operative orientation and thus is adapted to sealingly close the opening 1118 when the sealing element 1120 is not compressed. It is noted that the sealing element 1120 is biased to its normally closed operative orientation when no stress is applied thereupon. A fluid flow passage 1130 is defined by the inner volume of the sealing element 1120 and the inner volume of the male luer portion 1114, however fluid flow is not permitted through the fluid flow passage 1130 when the slit 1126 is closed and the second selectably openable end 1124 provides a swabbable surface that may be cleaned by the physician in order to prevent contamination.
It is noted that the sealing element 1120 is biased to its normally closed position once a compression force exerted thereon is removed.
It is appreciated that the second luer-actuated valve assembly 1102 is a male luer-actuated valve assembly which is similar to or commercially available from various manufacturers, such as Elcam Medical ACAL, Kibbutz Bar′am, Israel.
The second luer-actuated valve assembly 1102 preferably includes a housing 1140 having a male luer portion 1142 at one end and a female luer portion 1144 with an externally threaded portion 1145 at an opposite end. A forward housing portion 1146 generally surrounds the male luer portion 1142 and defines a rearwardly facing shoulder surface 1150 adjacent the forward end thereof. The housing 1140 is adapted for receiving a resilient sealing element 1152, which has a forward end 1154 with a selectably openable slit 1156. It is noted that the male luer portion 1142 has an opening 1160 and when no pressure is exerted on the sealing element 1152, the forward end 1154 of the sealing element 1152 is disposed near the opening 1160 of the male luer portion 1142, thereby urging sealable closing of the openable slit 1156. Once pressure is exerted on the sealing element 1152 by an actuator 1162, the sealing element 1152 is urged to be displaced rearwardly, thus disengaging the forward end 1154 thereof from opening 1160 and thus causing opening of the slit 1156.
It is noted that the sealing element 1152 is biased to its normally closed operative orientation when no stress is applied thereupon. A fluid flow passage 1170 is defined by the inner volume of the sealing element 1152 and partially the inner volume of the male luer portion 1142, however fluid flow is not permitted through the fluid flow passage 1170 when the slit 1156 is closed and the opening 1160 provides a swabbable surface that may be cleaned by the physician in order to prevent contamination.
It is noted that the sealing element 1152 is biased to its normally closed position once force exerted thereon is removed.

It is a particular feature of an embodiment of the present invention that upon connection of both the first and the second luer-actuated valve assemblies 1100 and 1102 to the connector body 1000, a fluid flow passage is established between two medical tubes, each of which is adapted to be connected to the respective male luer portion 1114 of the first luer-actuated valve assembly 1000 and to the female luer portion 1144 of the second luer-actuated valve assembly 1102.

The fluid flow passage is established from a first medical tube that is adapted to be connected to the male luer portion 1114 of the first luer-actuated valve assembly 1100, through the fluid flow passage 1130 thereof, via slit 1126 of the sealing element 1120 and further through the inner volume of the male luer portion 1142 of the second luer-actuated valve assembly 1102 and through slit 1156 of the sealing element 1152 into fluid flow passage 1170 of the second luer-actuated valve assembly 1102 and finally into a second medical tube that is adapted to be connected to the female luer portion 1144 of the second luer-actuated valve assembly 1102, which leads to a desired treatment site within the body of the patient. It is noted that the fluid flow direction can be established in an opposite direction.
It is appreciated that the first and second medical tubes are adapted to be positioned in a certain treatment area within the patient's body, thus dis-location of one of the medical tubes from its desired position may require replacement of the entire medical set in absence of a connector such as the connector body 1000 constructed and operative in accordance with an embodiment of the present invention.
It is noted that compression forces that the luer-actuated valve assemblies 1100 and 1102 exert on each other are enabled by the fact that both luer-actuated valve assemblies 1100 and 1102 are held in place relative to the connector body 1000 due to snap-fit connection therebetween.
The connector body 1000 is preferably disposable in case the respective snap connections between snap portion 1040 and forwardly facing shoulder surface 1115 provided between the connector body 1000 and the first luer-actuated valve assembly 1100 and the snap portion 1030 and rearwardly facing shoulder surface 1150 provided between the connector body 1000 and the second luer-actuated valve assembly 1102 are deformable, such that additional engagement of one of the luer-actuated valve assemblies 1100 and 1102 with the connector body 1000 is not intended after first use.
It is a particular feature of an embodiment of the present invention that in this operative orientation there is no relative axial displacement along longitudinal axis 1003 between the connector body 1000, the first luer-actuated valve assembly 1100 and the second luer-actuated valve assembly 1102 up until a predetermined tensile force is exerted on one of the second luer-actuated valve assemblies 1100 and 1102. This predetermined tensile force can either enable disengagement of the first luer-actuated valve assembly 1100 from the snap portion 1040 of second snap fingers 1022 of the connector body 1000 or disengagement of the second luer-actuated valve assembly 1102 from the snap portion 1030 of the first snap fingers 1020 of the connector body 1000.
It is noted that one of the luer actuated valve assemblies 1100 and 1102 may be disconnected upon application of a different tensile force magnitude, specifically seen in this embodiment of the present invention that snap portions 1040 extend radially inwardly to a lesser extent in comparison with snap portions 1030, thus the first luer actuated valve assembly 1100 is intended to be disconnected first from the connector body 1000. Alternatively, the connector body 1000 can be designed differently such that the second luer actuated valve assembly 1102 is disconnected first, in case snap portions 1030 extend radially inwardly to a lesser extent than snap portions 1040.
It is a particular feature of an embodiment of the present invention that preferably the engagement between snap portion 1040 of second snap fingers 1022 of the connector body 1000 and the forwardly facing shoulder 1115 of the first luer-actuated valve assembly 1100 is designed to be weaker than the engagement between snap portion 1030 of the first snap fingers 1020 of the connector body 1000 and the 1020 of the second luer-actuated valve assembly 1102, such that upon exertion of tensile force, the first luer-actuated valve assembly 1100 is disconnected first from the connector body 1000. Alternatively, engagement between the connector body 1000 and the first and second luer-actuated valve assemblies 1100 and 1102 may be of a similar extent.
It is noted that both the first and the second luer-actuated valve assemblies 1100 and 1102 are freely rotatable about axis 1003 while being engaged with the connector body 1000 without causing disengagement of the luer-actuated valve assemblies 1100 and 1102 therefrom.

It is a particular feature of an embodiment of the present invention that upon disconnection of the first luer-actuated valve assembly 1100 from the connector body 1000, both of the luer-actuated valve assemblies 1100 and 1102 are automatically bidirectionally closed, thus preventing fluid flow passage out of each of the two medical tubes due to the fact that the first and second luer-actuated valve assemblies 1100 and 1102 activate each other once they are both engaged with the connector body 1000.
Upon disengagement of the first luer-actuated valve assembly 1100 from the connector body 1000, the female luer portion 1112 of the first luer-actuated valve assembly 1100 urges biasing of the sealing element 1152 of the second luer-actuated valve assembly 1102 into its normally closed operative orientation, when slit 1156 is closed. Additionally, and simultaneously, male luer portion 1142 of the second luer-actuated valve assembly 1102 disengages from sealing element 1120 of the first luer-actuated valve assembly 1100, thus causes biasing thereof to its normally closed operative orientation, when the slit 1126 is closed.
Closing of both slits 1156 and 1126 prevents fluid flow passage from the first luer-actuated valve assembly 1100 to the second luer-actuated valve assembly 1102 and eventually into the treatment site within the body of the patient, thus also preventing possible contamination of the treatment site.
Upon discarding of the breakaway intra-medical tubing connector assembly 1000, two sealed and swabbale luer-actuated valve assemblies 1100 and 1102 are provided, which obviate the need to replace the entire medical set, and only requires replacement of the connector body 1000.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the connector body 1000 the catheter or other medical tube associated with one of the luer-actuated valve assemblies 1100 and 1102 remains in its position within the treatment site and the luer-actuated valve assemblies 1100 and 1102 are safely sealed once one of the luer-actuated valve assemblies 1100 and 1102 is disconnected from the connector body 1000. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 1100 and 1102 and the ability to clean the openable end 1124 of the sealing element 1120.
It is noted that alternatively disconnection of one of the luer-actuated valve assemblies 1100 and 1102 from the connector body 1000 may be intentional in order to provide the physician with access point to the IV line. Once one of the luer-actuated valve assemblies 1100 and 1102 is exposed, it may be used for administering medicament into the treatment site within the patient body or alternatively for withdrawing a blood sample from the patient's body.
It is a particular feature of an embodiment of the present invention that the connector body 1000 associated with medical connectors, such as luer-actuated valve assemblies 1100 and 1102 enables both safe unintentional disconnection of one of the luer-actuated valve assemblies and provides access point to the IV line through the exposed sealing element 1120 or 1152 when one of the luer-actuated valve assemblies 1100 and 1102 is intentionally disconnected.

A first aperture 1380 is defined by the plurality of snap portions 1350 at the first open end 1310 of the connector body 1302 and a second aperture 1382 is defined by the plurality of snap portions 1370 at the second open end 1312 of the connector body 1302. A through bore 1390 extends axially longitudinally along axis 1301, through connector body 1302 from the first aperture 1380 to the second aperture 1382.
It is noted that the plurality of first cut-outs 1330 provides for relative resiliency of the first open end 1310 of the connector body 1302 and the plurality of second cut-outs 1340 provides for relative resiliency of the second open end 1312 of the connector body 1302, thus allowing for radial deformation of the first and second open ends 1310 and 1312 of the connector body 1302 upon exertion of pressure thereon.

The shuttle portion 1400 has a first tubular end portion 1410 having a first open end 1412 and a second tubular end portion 1414 having a second open end 1416. The first tubular end portion 1410 defines an outer circumferential surface 1420 and the second tubular end portion 1414 defines an outer circumferential surface 1422.

It is appreciated that the first and second luer-actuated valve assemblies 1500 and 1502 are commercially available from various manufacturers, such as Haemopharm, Halkey-Roberts, Paolo Gobbi Frattini S.r.l. It is noted that both first and second luer-actuated valve assemblies 1500 and 1502 are preferably identical. Alternatively, two different first and second luer-actuated valve assemblies 1500 and 1502 can be used with the breakaway intra-medical tubing connector assembly 1300.
It is noted that first and second luer-actuated valve assemblies 1500 and 1502 are preferably substantially similar to first and second luer-actuated valve assemblies 400 and 402 which are described in detail with reference to

It is noted that attachment of the first and second luer-actuated valve assemblies 1500 and 1502 to the connector body 1302 is enabled due to the resilient characteristics of the connector body 1302, which enables outward deflection of first arms 1342 due to first cut-outs 1330 formed therebetween. Similarly, second arms 1362 can deflect outwardly due to second cut-outs 1340 formed therebetween.
It is a particular feature of an embodiment of the present invention that upon connection of both the first and the second luer-actuated valve assemblies 1500 and 1502 to the breakaway intra-medical tubing connector assembly 1300, a fluid flow passage is established between two medical tubes, each of which is adapted to be connected to the respective male luer portion 414 of the first and second luer-actuated valve assemblies 1500 and 1502.
It is a further particular feature of an embodiment of the present invention that the inner diameter of the fluid flow passage provided between the first and second luer-actuated valve assemblies 1500 and 1502 is substantially the same as the diameter of the thoroughgoing bore 1424 of the connector element 1304.

It is appreciated that the first and second medical tubes are adapted to be positioned in a certain treatment area within the patient's body, thus dis-location of one of the medical tubes from its desired position may require replacement of the entire medical set in absence of a connector such as the breakaway intra-medical tubing connector assembly 1300 constructed and operative in accordance with an embodiment of the present invention.
It is noted that compression forces exerted on both luer-actuated valve assemblies 1500 and 1502 by the connector element 1304 and subsequent opening of the respective slits 423 of the luer-actuated valve assemblies 1500 and 1502 are enabled by the fact that both luer-actuated valve assemblies 1500 and 1502 are held in place relative to the breakaway intra-medical tubing connector assembly 1300 due to snap-fit connection between both luer-actuated valve assemblies 1500 and 1502 and the connector body 1302.
It is a particular feature of an embodiment of the present invention that in this second operative orientation of the intra-medical tubing connector assembly 1300, there is no relative axial displacement along longitudinal axis 1301 between the connector body 1302, the connector element 1304, the first luer-actuated valve assembly 1500 and the second luer-actuated valve assembly 1502, up until a predetermined tensile force is exerted on one of the luer-actuated valve assemblies 1500 or 1502, which can either enable disengagement of the first luer-actuated valve assembly 1500 from the plurality of first snap portions 1350 of the connector body 1302 or disengagement of the second luer-actuated valve assembly 1502 from the plurality of second snap portions 1370 of the connector body 1302.
The breakaway intra-medical tubing connector assembly 1300 is preferably disposable in case the respective snap connections 1350 and 1370 provided on the connector body 1302 are deformable, such that additional engagement of one of luer-actuated valve assemblies 1500 and 1502 with the connector body 1302 is not intended after first use.
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 1300, constructed and operative in accordance with an embodiment of the present invention. It is noted that both the first and the second luer-actuated valve assemblies 1500 and 1502 may be freely rotated about axis 1301 while being engaged with the intra-medical tubing connector assembly 1300, without causing disengagement of the luer-actuated valve assemblies 1500 and 1502 therefrom.
It is further noted that upon connection of one of the luer actuated valve assemblies 1500 and 1502, the connector element 1304 is axially slidably moveable and thus provides for both of the luer-actuated valve assemblies 1500 and 1502 to remain sealed up until both luer-actuated valve assemblies 1500 and 1502 are connected to the connector body 1302, which provides for opening of the sealing members 420 of both luer-actuated valve assemblies 1500 and 1502.

It is noted that one of the luer actuated valve assemblies 1500 and 1502 may be disconnected upon application of a different tensile force magnitude. In case that snap portion 1370 extends radially inwardly to a lesser extent in comparison with snap portion 1350, then the second luer actuated valve assembly 1502 is intended to be disconnected first from the connector body 1300. Alternatively, the connector body 1300 can be designed differently such that the first luer actuated valve assembly 1500 is disconnected first, in case snap portion 1350 extends radially inwardly to a lesser extent in comparison with snap portion 1370.
It is noted that in this third operative orientation of the intra-medical tubing connector assembly 1300, the second luer-actuated valve assembly 1502 remains partially connected to the connector body 1302 such that the first tubular portion 1410 of the connector element 1304 still protrudes into female luer portion 412 of the first luer actuated valve assembly 1500 and the second tubular portion 1414 of the connector element 1304 still protrudes into female luer portion 412 of the second luer-actuated valve assembly 1502.

It is a particular feature of an embodiment of the present invention that even during partial disconnection of the second luer-actuated valve assembly 1502 from the breakaway intra-medical tubing connector assembly 1300, both of the luer-actuated valve assemblies 1500 and 1502 are immediately automatically bidirectionally closed due to the fact that the connector element 1304 is axially floating within the connector body 1302, thus preventing fluid flow passage out of each of the two medical tubes.
It is seen in
Further, upon partial disengagement of the second luer-actuated valve assembly 1502 from the breakaway intra-medical tubing connector assembly 1300, the first tubular end portion 1410 of the shuttle portion 1400 of connector element 1304 partially disengages the sealing element 420 of the first luer-actuated valve assembly 1500, and thereby causing the sealing element 420 to assume its normally closed operative orientation, when slit 426 is closed. Upon disengagement of the connector element 1304 from one of the luer-actuated valve assemblies 1500 and 1502, both valves are automatically biased to their normally closed operative orientations, where slits 426 are closed, thus effectively sealing both luer-actuated valve assemblies 1500 and 1502 and preventing passage of any fluid passage through the IV line.
Closing of both slits 426 prevents fluid flow passage from the first luer-actuated valve assembly 1500 via throuhgoing bore 1424 of connector element 1304 into the second luer-actuated valve assembly 1502 and eventually into the treatment site within the body of the patient, thus also preventing possible contamination of the treatment site.
It is also seen in
It is a further particular feature of an embodiment of the present invention that the sealing elements 420 of the first and second luer-actuated valve assemblies 1500 and 1502 are biased to their closed operative orientation by means of the partial disengagement of shuttle portion 1400 of the connector element 1304 of the intra-medical tubing connector assembly 1300 from sealing elements 420. This partial disengagement is provided by the fact that one of the housings 410 of the first or the second luer-actuated valve assemblies 1500 or 1502 is no longer supported and held in place by the respective snap portions 1350 or 1370 of the connector body 1302 of the intra-medical tubing connector assembly 1300.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 1300, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 1500 and 1502 remains in its position within the treatment site and the luer-actuated valve assemblies 1500 and 1502 are safely sealed once one of the luer-actuated valve assemblies 1500 and 1502 is even slightly disconnected from the breakaway intra-medical tubing connector assembly 1300. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 1500 and 1502.
It is noted that alternatively disconnection of one of the luer-actuated valve assemblies 1500 and 1502 from the breakaway intra-medical tubing connector assembly 1300 may be intentional in order to provide the physician with access point to the IV line. Once one of the luer-actuated valve assemblies 1500 and 1502 is exposed, it may be used for administering medicament into the treatment site within the patient body or alternatively for withdrawing a blood sample from the patient's body.

It is a particular feature of an embodiment of the present invention that upon disconnection of the second luer-actuated valve assembly 402 from the breakaway intra-medical tubing connector assembly 1300 from the connector body 102, both of the luer-actuated valve assemblies are automatically bidirectionally closed, thus preventing fluid flow passage out of each of the two medical tubes. Upon discarding of the breakaway intra-medical tubing connector assembly 1300, two sealed and swabbale luer-actuated valve assemblies 1500 and 1502 are provided, which obviate the need to replace the entire medical set, and only requires replacement of the breakaway intra-medical tubing connector assembly 1300.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 1300, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 1500 and 1502 remains in its position within the treatment site and the luer-actuated valve assemblies 1500 and 1502 are safely sealed once one of the luer-actuated valve assemblies 1500 and 1502 is disconnected from the breakaway intra-medical tubing connector assembly 1300. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 1500 and 1502 and the ability to clean the exterior surface of the sealing element 420.
It is noted that alternatively disconnection of one of the luer-actuated valve assemblies 1500 and 1502 from the breakaway intra-medical tubing connector assembly 1300 may be intentional in order to provide the physician with access point to the IV line.

It is a particular feature of an embodiment of the present invention that the breakaway intra-medical tubing connector assembly 1300 associated with medical connectors, such as luer-actuated valve assemblies 1500 and 1502 enables both safe unintentional disconnection of one of the luer-actuated valve assemblies and provides access point to the IV line through the exposed sealing element 420 when one of the luer-actuated valve assemblies 1500 and 1502 is intentionally disconnected.

In accordance with an embodiment of the present invention, the first tubular portion 2140 and the second tubular portion 2142 are male luers, which preferably meet ISO standard 80369-7.

The first annular end protrusion 2130 defines a first generally rounded forwardly facing shoulder 2152, which faces the first end 2102 and a second rearwardly facing shoulder 2154 which faces the intermediate annular protrusion 2150. The second annular end protrusion 2132 defines a first generally rounded rearwardly facing shoulder 2156, which faces the second end 2104 and a second forwardly facing shoulder 2158 which faces the intermediate annular protrusion 2150.
The intermediate annular protrusion 2150 defines a forwardly facing shoulder 2160 facing the first annular end protrusion 2130 and a rearwardly facing shoulder 2162 facing the second annular end protrusion 2132.

The second snap-fit fitting 2022 is an integrally made element arranged along longitudinal axis 2001, and preferably made of plastic, such as Polypropylene, Polycarbonate, Polyethylene. The second snap-fit fitting 2022 is a generally cylindrical hollow element having a first open end 2200 and a second open end 2202 and a thoroughgoing bore 2204 extending along longitudinal axis 2001.
An internally threaded portion 2210 forms part of the thoroughgoing bore 2204 of the second snap-fit fitting 2020 and is disposed adjacent first open end 2200. The internally threaded portion 2210 extends longitudinally along axis 2001 and preferably meets ISO standard 80369-7. The thoroughgoing bore 2204 further includes an intermediate bore portion 2212 having a first diameter and extending rearwardly of the internally threaded portion 2210 and terminating at a circumferential inwardly radially protruding annular flange 2220 having a forwardly facing shoulder 2222 and a rearwardly facing shoulder 2224. The forwardly facing shoulder 2222 is facing the first open end 2200 and preferably lies in a plane, which is generally perpendicular to axis 2001. It is noted, that the radially protruding annular flange 2220 may alternatively be formed of several discrete radially spaced portions instead of a continuous circumferential flange.
Extending rearwardly from the annular flange 2220 is an annular bore portion 2230 having a second diameter, generally greater than the first diameter and terminating at the second open end 2202.
The second snap-fit fitting 2022 includes a forward portion 2240 having a first outer diameter and extending rearwardly from the first open end 2200 and a rearward portion 2242 having a second outer diameter, which is generally smaller than the first outer diameter. The rearward portion 2242 extends from the second open end 2202 to a rearwardly facing shoulder 2244, which is formed between the forward portion 2240 and the rearward portion 2242.
The rearward portion 2242 defines an outer surface 2250, on which a generally circumferential snap protrusion 2252 is formed. The snap protrusion 2252 extends generally radially outwardly from outer surface 2250 and defines a forwardly facing shoulder 2256, which preferably lies in a plane that is perpendicular to axis 2001, a longitudinal outwardly facing surface 2257 and a rearwardly facing tapered surface 2258. It is noted, that the snap protrusion 2252 may alternatively be formed of several discrete radially spaced portions instead of a continuous circumferential protrusion.

It is a particular feature of an embodiment of the present invention that the connector element 2004 is substantially fixedly mounted between the first snap fit fitting 2020 and the second snap fit fitting 2022 due to the intermediate annular protrusion 2150 that is fixedly held between the two snap fit fittings 2020 and 2022. Specifically, the forwardly facing shoulder 2160 of the intermediate annular protrusion 2150 generally abuts the rearwardly facing shoulder 2224 of the second snap fit fitting 2022 and the rearwardly facing shoulder 2162 of the intermediate annular protrusion 2150 generally abuts the forwardly facing surface 2054 of the first snap fit fitting 2020. It is appreciated that the fixed mounting of the connector element 2004 within the two snap-fit fittings 2020 and 2022 facilitates de-bubbling of the medical tube contents before connection of the breakaway intra-medical tubing connector assembly 2000 to the medical tube, specifically one of the tubular portions 2140 or 2142 of the connector element 2004 can be at least partially inserted into the medical tube for dispensing of a certain amount of fluid from the medical tube, for example in order to prime the IV line and remove any trapped air-bubbles therefrom.
It is noted that alternatively, in absence of the intermediate annular protrusion 2150, the connector element 2004 maybe freely slidable with respect to the first and second snap fit fittings 2020 and 2022 along longitudinal axis 2001 up to engagement of either the first annular end protrusion 2130 or the second annular end protrusion 2132 of the connector element 2004 with the respective annular flange 2220 of the second snap fit fitting 2022 and flange 2050 of the first snap fit fitting 2020.
It is a particular feature of an embodiment of the present invention that the first snap-fit fitting 2020 is lockingly connected to the second snap fit fitting 2022 prior to use by means of the bayonet mechanism 2024, and the connector element 2004 is inserted through the through bores 2034 and 2204 of the respective first and second snap fit fittings 2020 and 2022. It is noted that in this prior to use operative orientation, the snap-fit fittings 2020 and 2022 cannot be disconnected from each other in response to tensile force exerted on one of the snap-fit fittings 2020 and 2022 along longitudinal axis 2001, thus providing for enhanced secured connection between the first and second snap-fit fittings 2020 and 2022 during connection of the luer actuated valves 2300 and 2302 thereto.
It is specifically seen that the first snap-fit fitting 2020 and the second snap-fit fitting 2022 are locked to each other by means of the bayonet mechanism 2024, particularly by means of cooperation of the safety pins 2026 of second snap-fit fitting 2022 within the openings 2094 of the locking members 2025 of the first snap-fit fitting 2020, such that axial displacement between the first and second snap-fit fittings 2020 and 2022 along longitudinal axis 2001 is inhibited as long as the safety pins 2026 are located within the openings 2094.
It is noted that alternatively, any other locking mechanism may be used in order to safely lock the two snap-fit fittings 2020 and 2022 to each other. Exemplary locking mechanisms are a locking sleeve, safety pin, thread and a pivotable hinge.

It is noted that tapered surface 2258 is provided on snap connection 2252 of the second snap fit fitting 2022 and a corresponding tapered protrusion 2072 is provided on the first snap fit fitting 2020 for facilitating connection of the two snap fit fittings 2020 and 2022.
It is a further particular feature of an embodiment of the present invention that an optional sealing is provided between the two snap fit fittings 2020 and 2022 and between the connector element 2004 by means of engagement of the outer surface 2250 of the rearward portion 2242 of the second snap fit fitting 2022 and the inner circumferential surface 2063 of the annular portion 2062 of the first snap fit fitting 2020.
It is noted that in this assembled operative orientation of the breakaway intra-medical tubing connector assembly 2000, the snap fit fittings 2020 and 2022 are static with respect to each other. The connector element 2004 is mounted through the through bore 2034 of the first snap fit fitting 2020 and the through bore 2204 of the second snap fit fitting 2022, preferably such that the first annular end protrusion 2130 of the connector element 2004 is generally disposed within the internally threaded portion 2210 of the second snap fit fitting 2022 and is generally forwardly spaced from flange 2220. The second annular end protrusion 2132 of the connector element 2004 is generally disposed within the internally threaded portion 2040 of the first snap fit fitting 2020 and is generally rearwardly spaced from flange 2050.
It is particularly seen in
It is a particular feature of an embodiment of the present invention that the connector element 2004 is only axially slidable with respect to both snap fit fittings 2020 and 2022 in use, upon release of the locking mechanism 2024 and application of tensile force on one of the snap-fit fittings 2020 and 2022 and their respective disconnection from each other.
It is a particular feature of an embodiment of the present invention that flange 2050 of the first snap-fit fitting 2020 extends radially inwardly to a different extent than flange 2220 of the second snap-fit fitting 2022. Alternatively, both flanges 2050 and 2220 extend radially inwardly to the same extent.
It is a further particular feature of an embodiment of the present invention that there is a minimal radial overlap between flange 2050 of the first snap-fit fitting 2020 and annular end protrusion 2132 of the connector element 2004. Similarly, there is a minimal radial overlap between flange 2220 of the second snap-fit fitting 2022 and annular end protrusion 2130 of the connector element 2004. Thus, in use, the flanges 2050 and 2220 of the two snap-fit fittings 2020 and 2022 respectively are used to prevent axial displacement of the connector element 2004 upon engagement of one of the end protrusions 2130 and 2132 with the respective flanges 2220 and 2050 as long as a predetermined threshold of tensile force is not applied on one of the snap-fit fittings 2020 and 2022.
Insertion of the connector element 2004 into both of the snap-fit fittings 2020 and 2022 is enabled by the respective tapered edges of the respective flanges 2050 and 2220. Specifically, rounded edge of end protrusion 2132 of the connector element 2004 engages the forwardly facing tapered edge of flange 2050 of the first snap-fit fitting 2020 and thus the end protrusion 2132 is inserted into bore 2034 of the first snap-fit fitting 2020. Similarly, rounded edge of end protrusion 2130 of the connector element 2004 engages the rearwardly facing tapered edge of flange 2220 of the second snap-fit fitting 2022 and thus the end protrusion 2130 is inserted into bore 2204 of the second snap-fit fitting 2022.

It is appreciated that the first and second luer-actuated valve assemblies 2300 and 2302 are preferably commercially available from various manufacturers, such as Haemopharm, Halkey-Roberts, Paolo Gobbi Frattini S.r.l, ICU, B.Braun. It is noted that both first and second luer-actuated valve assemblies 2300 and 2302 are preferably identical. Alternatively, two different first and second luer-actuated valve assemblies 2300 and 2302 can be used with the breakaway intra-medical tubing connector assembly 2000.
It is noted that first and second luer-actuated valve assemblies 2300 and 2302 are preferably substantially identical to first and second luer-actuated valve assemblies 400 and 402 which are described in detail hereinabove with reference to
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 2000, constructed and operative in accordance with an embodiment of the present invention. It is particularly noted that luer-actuated valve assemblies having an internal fluid flow passing within the sealing element can be used in conjunction with the breakaway intra-medical tubing connector assembly 2000, as well as luer-actuated valve assemblies having an external fluid flow passing around the sealing element. Some examples of valve assemblies with internal fluid flow are: Smartsite® of Alaris/Carefusion/Becton Dickinson; Microcline® of ICU Medical; In-Vision Plus® of RyMed; Clearlink® of Baxter; One-Link® of Baxter; Nexus TKO® of Nexus Medical; Caresite® of B.Braun Medical Inc.; Bionector® of Vygon. Some examples of valve assemblies with external fluid flow are: MaxZero™ of Becton Dickinson; MaxPlus™ of Carefusion/Becton Dickinson; Posiflow™ of Becton Dickinson; Ultrasite® of B.Braun Medical Inc.
It is a particular feature of an embodiment of the present invention that luer-actuated valve assemblies with an external fluid flow can be used in conjunction with the breakaway intra-medical tubing connector assembly 2000 due to the fact that the tubular portions 2140 and 2142 of the connector element 2004 are male luers, which preferably meet ISO standard 80369-7 and thus seal against the female luer portion of the luer-actuated valve assembly.
It is specifically seen in
It is further noted that the male luer portions 414 of each of the luer-actuated valve assemblies 2300 and 2302 are adapted to be connected to a medical tubing, such as for example, an IV line or a catheter.
It is a particular feature of an embodiment of the present invention that the connector element 2004 is preferably made of a relatively soft plastic material, such as Polyethylene for example, while the commercially available luer-actuated valve assemblies 2300 and 2302 are usually made of Polycarbonate. Due to this fact, the required tensile force for pulling the connector element 2004 out of the female portions of the luer-actuated valve assemblies 2300 and 2302 is minimized.
Spatial relationships between the various components of the breakaway intra-medical tubing connector assembly 2000 preferably remain the same as described with reference to

It is a particular feature of an embodiment of the present invention that upon connection of both the first and the second luer-actuated valve assemblies 2300 and 2302 to the breakaway intra-medical tubing connector assembly 2000, a fluid flow passage is established between two medical tubes, each of which is adapted to be connected to the respective male luer portion 414 of the first and second luer-actuated valve assemblies 2300 and 2302.
It is a further particular feature of an embodiment of the present invention that the inner diameter of the fluid flow passage provided between the first and second luer-actuated valve assemblies 2300 and 2302 is substantially the same as the diameter of the thoroughgoing bore 2120 of the connector element 2004.
Specifically, it is seen in
It is appreciated that the first and second medical tubes are adapted to be positioned in a certain treatment area within the patient's body, thus dis-location of one of the medical tubes from its desired position may require replacement of the entire medical set in absence of a connector such as the breakaway intra-medical tubing connector assembly 2000 constructed and operative in accordance with an embodiment of the present invention.
It is noted that compression forces exerted on both luer-actuated valve assemblies 2300 and 2302 by the connector element 2004 are enabled by the fact that both luer-actuated valve assemblies 2300 and 2302 are held in place relative to the breakaway intra-medical tubing connector assembly 2000 due to snap-fit connection between the two snap-fit fittings 2200 and 2202.
It is a particular feature of an embodiment of the present invention that during the connection of both luer actuated valve assemblies 2300 and 2302 to the breakaway intra-medical tubing connector assembly 2000, the two snap-fit fittings 2020 and 2022 are locked with respect to each other by means of the bayonet mechanism 2024, thus axial separation of the two snap-fit fittings 2020 and 2022 is prevented at this operative stage, irrespective of the magnitude of tensile force applied on the breakaway intra-medical tubing connector assembly 2000 along longitudinal axis 2001.
It is particularly seen in
The breakaway intra-medical tubing connector assembly 2000 is disposable in case the snap protrusion 2252 of the second snap-fit fitting 2022 is deformable, such that additional engagement of snap protrusion 2252 of the second snap-fit fitting 2022 with snap connection 2070 of the first snap-fit fitting 2020 is not intended after first use. Fluid tight and bacterial sealing is optionally provided between the snap-fit fittings 2020, 2022 and connector element 2004 in this operative orientation due to pressure engagement between inner circumferential surface 2063 of the first snap-fit fitting 2020 and outer surface 2250 of the second snap-fit fitting 2022.
It is noted that alternatively, any other type of luer-actuated valve assembly can be used in conjunction with the breakaway intra-medical tubing connector assembly 2000, constructed and operative in accordance with an embodiment of the present invention.

It is a particular feature of an embodiment of the present invention that in this unlocked operative position, the first snap-fit fitting 2020 is disconnectably snap-fittingly connected to the second snap fit fitting 2022 and the connector element 2004 is inserted through the through bores 2034 and 2204 of the respective first and second snap fit fittings 2020 and 2022. It is noted that each of the snap-fit fittings 2020 and 2022 can be disconnected from each other in response to tensile force exerted on one of the snap-fit fittings 2020 and 2022 along longitudinal axis 2001.

It is seen in this first intermediate stage of disconnection of the breakaway intra-medical tubing connector assembly 2000 that the snap connection between the two snap-fit fittings 2020 and 2022 is broken, but the connector element 2004 is not yet pulled out of both luer-actuated valve assemblies 2300 and 2302.

It is a particular feature of an embodiment of the present invention that upon application of sufficient tensile force on one of the snap-fit fittings 2020 or 2022, the connector element 2004 is pulled out of one of the luer-actuated valve assemblies 2300 and 2302 due to the friction force between the other one of the luer-actuated valve assemblies 2300 and 2302 and the connector element 2004, which holds the other end of the connector element 2004 at least partially inserted into the luer actuated valve assembly 2300 or 2302. Specifically, the friction force created between the opposite one of the tubular portions 2140 and 2142 of the connector element 2004 that is at least partially inserted into one of the female portions 412 of the luer actuated valve assemblies 2300 and 2302.
Specifically, there is a three-step disconnection process of the breakaway intra-medical tube connector assembly 2000 upon application of a sufficient tensile force by the user on one of the snap-fit fittings 2020 and 2022:
Firstly, the two snap-fit fittings 2020 and 2022 are disconnected by breaking the snap connection between snap connection 2070 and snap protrusion 2252, thereby providing a visual indication for the user that the medical tubes connected to the respective male luer portions 414 of the luer actuated valve assemblies 2300 and 2302 are now disconnected.
Secondly, further application of the tensile force by the user urges axial displacement of the connector element 2004 relative to one of the snap-fit fittings 2020 and 2022 along longitudinal axis 2001, such that one of the tubular portions 2140 and 2142 of the connector element 2004 is pulled out of the respective luer-actuated valve 2300 and 2302 due to the friction forces created between the opposite ones of tubular portions 2140 and 2142 and the luer-actuated valves 2300 and 2302. The connector element 2004 is relatively displaced axially along axis 2001 up to engagement of one of the end protrusions 2130 or 2132 of the connector element 2004 with one of the respective inner flanges 2220 or 2050 of the respective snap-fit fittings 2022 and 2020.
Thirdly, upon engagement of one of the end protrusions 2130 or 2132 of the connector element 2004 with one of the respective inner flanges 2220 or 2050 of the respective snap-fit fittings 2022 and 2020, the connector element 2004 is urged to be displaced axially along longitudinal axis 2001 relative to the other snap-fit fitting 2020 and 2022 up to engagement of another one of the end protrusions 2130 or 2132 of the connector element 2004 with another one of the respective inner flanges 2220 or 2050 of the respective snap-fit fittings 2022 and 2020, thus urging the connector element 2004 out of the other one of the luer-actuated valve assemblies 2300 and 2302.

Alternatively, the second tubular portion 2142 of the connector element 2004 may be pulled out first from the first luer-actuated valve assembly 2300 upon application of tensile force by the user, as is particularly seen in

It is noted that additionally, upon disconnection of the snap-fit fittings 2020 and 2022, the connector element 2004 is urged to be displaced axially along longitudinal axis 2001 and out of the luer-actuated valve assembly 2300 due to the biasing force of the sealing element 420 of the first luer-actuated valve assembly 2300, that is applied upon the connector element 2004. Similarly, the connector element 2004 is urged to be displaced axially along longitudinal axis 2001 and out of the second luer-actuated valve assembly 2302, due to the biasing force of the sealing element 420 of the second luer-actuated valve assembly 2302 that is applied upon the connector element 2004. This biasing force ensures that the sealing element 420 returns to its normally closed operative orientation, whereas the selectively closeable slit 426 is closed. It is noted that the biasing force is relatively low and the friction forces between the connector element 2004 and the female portion 412 of the luer actuated valve assembly provide a contra thereto.

It is noted that all spatial relationships between the different components of the breakaway intra-medical tubing connector assembly 2000 and the luer actuated valve assemblies 2300 and 2302 remain generally identical to the relationships described with reference to
Upon further application of tensile force on one of the snap-fit fittings 2020 and 2022, there is a further relative axial displacement between one of the snap-fit fittings 2020 and 2022 and between the connector element 2004.

It is seen in this prior to disconnection orientation of the breakaway intra-medical tubing connector assembly 2000 that the connector element 2004 is now pulled out of both luer-actuated valve assemblies 2300 and 2302. It is noted that this is also a momentary stage and upon further application of tensile force by the user along longitudinal axis 2001, the breakaway intra-medical tubing connector assembly 2000 subsequently assumes a disconnected orientation, as is described in detail hereinbelow with reference to
It is noted that the third disconnection step is illustrated and described with reference to
It is a particular feature of an embodiment of the present invention that upon application of sufficient tensile force on one of the snap-fit fittings 2020 or 2022, the connector element 2004 is urged out of the other one of the luer-actuated valve assemblies 2300 and 2302 by means of engagement of one of the end protrusions 2130 and 2132 with one of the respective flanges 2050 and 2220. Upon further application of tensile force, relative axial displacement is provided between the connector element 2004 and one of the snap-fit fittings 2020 and 2022 up to engagement between the other one of end protrusions 2130 and 2132 with another one of the respective flanges 2050 and 2220. The engagement between the first one of the end protrusions 2130 and 2132 with the respective first one of the flanges 2050 and 2220 is described hereinabove with reference to

It is a further particular feature of an embodiment of the present invention that the inner diameter of the flange 2220 is slightly smaller than the outer diameter of the first annular end protrusion 2130 and inner diameter of the flange 2050 is slightly smaller than the outer diameter of the second annular end protrusion 2132, thus upon engagement of respective end protrusions 2130, 2132 with the respective flanges 2220 and 2050, the tubular portion 2140 of the connector element 2004 is pulled out of the second luer actuated valve assembly 2302 and tubular portion 2142 of the connector element 2004 is pulled out of the first luer actuated valve assembly 2300.
It is noted that in this prior to disconnection orientation, the connector element 2004 remains partially within both snap-fit fittings 2020 and 2022, whereas end protrusion 2130 of the connector element 2004 engages flange 2220 of the second snap-fit fitting 2022 and end protrusion 2132 of the connector element 2004 engages flange 2050 of the first snap-fit fitting 2020, just prior to full disconnection of the breakaway intra-medical tubing connector assembly 2000.
It is noted that additionally, upon disconnection of the snap-fit fittings 2020 and 2022, the connector element 2004 is urged to be displaced axially along longitudinal axis 2001 and out of the luer-actuated valve assembly 2300 due to the biasing force of the sealing element 420 of the first luer-actuated valve assembly 2300, that is applied upon the connector element 2004. Similarly, the connector element 2004 is urged to be displaced axially along longitudinal axis 2001 and out of the second luer-actuated valve assembly 2302, due to the biasing force of the sealing element 420 of the second luer-actuated valve assembly 2302 that is applied upon the connector element 2004. This biasing force ensures that the sealing element 420 returns to its normally closed operative orientation, whereas the selectively closeable slit 426 is closed. It is noted that the biasing force is relatively low and the friction forces between the connector element 2004 and the female portion 412 of the luer actuated valve assembly provide a contra thereto.

It is noted that alternatively, the second tubular portion 2142 of the connector element 2004 can be removed entirely from the first snap-fit fitting 2020.
It is noted that there is a minimal radial overlap engagement between flange 2220 and first annular end protrusion 2130 and a minimal radial overlap engagement between flange 2050 and second annular end protrusion 2132, and application of sufficient tensile force overcomes one of these engagements, thus the connector element 2004 is completely removed from one of the snap-fit fittings 2020 and 2022. In this particular example, the connector element 2004 is removed from the second snap-fit fitting 2022 and the second annular end protrusion 2132 remains adjacent flange 2050 of the first snap-fit fitting 2020, thus preventing the connector element 2004 from falling out from the breakaway intra-medical tubing connector assembly 2000.
It is a particular feature of an embodiment of the present invention that preferably one of the inner flanges 2220 and 2050 has a smaller inner diameter than the other, such that it is pre-defined which side of the connector element 2004 is disconnected first from its respective luer-actuated valve assembly 2300 or 2302. If the inner diameter of flange 2220 is smaller than the inner diameter of flange 2050, then the connector element 2004 is removed entirely from the first snap-fit fitting 2020. Alternatively, if the inner diameter of flange 2050 is smaller than the diameter of inner flange 2220, then the connector element 2004 is removed entirely from the second snap-fit fitting 2022.
Alternatively, both inner flanges 2220 and 2050 may have the same diameter.
It is a particular feature of an embodiment of the present invention that upon disconnection of the two snap-fit fittings 2020 and 2022 from each other and subsequent removal of the connector element 2004 out of both luer-actuated valve assemblies 2300 and 2302, both of the luer-actuated valve assemblies 2300 and 2302 are automatically bidirectionally closed, thus preventing fluid flow passage from each of the two medical tubes. Upon discarding of the breakaway intra-medical tubing connector assembly 2000, two sealed and swabbale luer-actuated valve assemblies 2300 and 2302 are provided, which obviate the need to replace the entire medical set, and only requires replacement of the breakaway intra-medical tubing connector assembly 2000.
In this third operative orientation, as seen in this particular example, the first tubular portion 2140 of the connector element 2004 protrudes outwardly from the first snap-fit fitting 2020 and the second tubular portion 2142 of the connector element 2004 is fully surrounded by the first snap-fit fitting 2020.
The first snap-fit fitting 2020 can be threadably disengaged from the first luer-actuated valve assembly 2030 and the second snap-fit fitting 2022 can be threadably disengaged from the second luer-actuated valve assembly 2302, thus leaving the luer-actuated valve assemblies 2300 and 2302 along with the medical tubes associated therewith within the desired treatment location. Following disconnection of the snap-fit fittings 2020 and 2022 from the first and second luer-actuated valve assemblies 2300 and 2302, the valve assemblies are swabbable and can be cleaned by the user and subsequently ready to be used again with another breakaway intra-medical tubing connector assembly 2000.
It is noted that tensile force exerted on the medical set such as IV line may be unintentional, but due to the presence of the breakaway intra-medical tubing connector assembly 2000, the catheter or other medical tube associated with one of the luer-actuated valve assemblies 2300 and 2302 remains in its position within the treatment site and the luer-actuated valve assemblies 2300 and 2302 are safely sealed once the snap-fit fittings 2020 and 2022 are disconnected from each other. Therefore, no fluid can unintentionally flow out of the IV line and risk of contamination of the treatment site is prevented due to sealing of the luer-actuated valve assemblies 2300 and 2302 and the ability to clean the exterior surface of the sealing element 420 remains.
It is a particular feature of an embodiment of the present invention that the breakaway intra-medical tubing connector assembly 2000 associated with medical connectors, such as luer-actuated valve assemblies 2300 and 2302 enables safe unintentional disconnection of one of the luer-actuated valve assemblies.
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of various features described hereinabove as well as variations and modifications thereof which are not in the prior art.
