Various exemplary embodiments of the invention relate to catheters.
Catheter assemblies are used to place a catheter properly into the vascular system of a patient. Once in place, catheters such as intravenous catheters may be used to infuse fluids including normal saline, medicinal compounds, and/or nutritional compositions into a patient in need of such treatment. Catheters additionally enable the removal of fluids from the circulatory system and monitoring of conditions within the vascular system of the patient.
It is an aspect of the present invention to provide a catheter assembly in which a clip provides needle protection but does not interlock the catheter hub to the needle shield. Instead, the catheter assembly incorporates an outer needle member, an inner needle member and a clip disposed in the inner needle member. The outer member interlocks the catheter hub based on the engagement of the opposing member in the inner member to a bore of the catheter hub. The needle protection arrangement can be used with existing catheter hubs and does not require any special features to be provided on the outside or inside of the catheter hub.
The foregoing and/or other aspects of the present invention can be achieved by providing a catheter assembly comprising a flexible catheter, a needle having a sharp distal tip, the needle disposed in the flexible catheter and moving from a first position that exposes the needle to a second position, an outer member that is configured to engage and disengage a catheter hub, an inner member disposed in the outer member, and a needle protection member disposed in the inner member, the needle protection member encloses at least a portion of the needle when the needle is in the second position.
The foregoing and/or other aspects of the present invention can further be achieved by providing a catheter assembly comprising a flexible catheter, a needle having a sharp distal tip, the needle disposed in the flexible catheter and moving from a first position that exposes the needle to a second position, an outer member configured to engage and disengage a catheter hub, an inner member disposed in the outer member, the inner member having an opposing member that engages the catheter hub when the needle is in the first position, and a needle protection member disposed in the inner member that encloses at least a portion of the needle when the needle is in the second position, wherein when the needle is in the second position, the inner member axially moves relative to the outer member causing the opposing member to disengage the catheter hub and allowing the outer member to disengage from the catheter hub.
The foregoing and/or other aspects of the present invention can also be achieved by providing a method of operating a catheter assembly comprising disposing a needle having a sharp distal tip in a flexible catheter and in a first position configured to receive blood, retracting the needle while maintaining blood flow through the flexible catheter, enclosing at least a portion of the needle by a needle protection member in a second position, and moving the needle protection member that is disposed in an inner member when retracting the needle in the second position which causes the inner member to axially move inside of an outer member and permits the outer member to disengage the catheter hub.
Additional and/or other aspects and advantages of the present invention will be set forth in the description that follows, or will be apparent from the description, or may be learned by practice of the invention.
The above aspects and features of the present invention will be more apparent from the description for the exemplary embodiments of the present invention taken with reference to the accompanying drawings, in which:
A catheter 10, as illustrated in
In accordance with various exemplary embodiments, the needle shield 20 includes an outer member 26, an inner member 28, and a resilient clip 30. The outer and inner members 26, 28 are preferably in the form of sleeves. The outer sleeve 26 connects to the catheter hub 14 and surrounds the inner sleeve 28, and the clip 30. The inner sleeve 28 is positioned in the outer sleeve 26 and is moveable in the axial direction relative to the outer sleeve 26. The clip 30 is connected to, and axially moveable with, the inner sleeve 28. The outer sleeve 26, inner sleeve 28, and clip 30 may be formed from a metal, elastomer, polymer, or composite material. In various exemplary embodiments, the outer sleeve 26 and the inner sleeve 28 are molded from a polymer material and the clip 30 is formed from a thin piece of resilient metal, such as stainless steel. The clip in the various embodiments disclosed can act as an exemplary needle protection member. The features of the exemplary embodiments of
In accordance with the exemplary embodiments depicted in
A catch 42 extends from the outer surface to engage or interlock with a protrusion 44 on the catheter hub 14 as best shown in
The catch 42 has a front edge, a back edge, and a pair of side edges. An opening or depression is formed between the front edge and the back edge to receive the catheter hub protrusion 44. The opening allows the catch 42 to be formed with a clearance approximately equal to, or slightly greater than the height of the projection 44, allowing the catch 42 to engage the front, back, and/or sides of the Luer thread projection 44 while minimizing the amount of material and space needed. In various exemplary embodiments, the opening may be omitted. The catch 42 resists premature release of the needle shield 20 from the catheter hub 14. The features of the exemplary embodiments of
In accordance with the exemplary embodiments depicted in
In an alternate embodiment of the inner sleeve 18, a bridge member (not shown) can be incorporated to improve the strength of the inner sleeve 18. Specifically, the top surface of the distal side 48 and the top surface of the proximal side 50 can be connected by a solid member having a similar length of the base 46. The inner sleeve 18 can be manufactured by injection molding, for example.
In another alternate embodiment, the foot 54 of the base 46 can be removed and the base 46 can be a solid member. According to this configuration, the inner sleeve 28 deforms in the outer sleeve 26 to achieve appropriate retention. The inner and outer sleeves 28, 26 are appropriately sized so that the inner sleeve 28 can also axially move inside and relative to the outer sleeve 26 upon applying a predetermined force. If a force less than the predetermined force is applied, the inner sleeve 28 does not move relative to the outer sleeve 26. Such a configuration improves moldability and manufacturability of the inner sleeve 28 and outer sleeve 26. The features of the exemplary embodiments of
In accordance with the exemplary embodiments depicted in
As the needle 12 is withdrawn from the catheter hub 14, the tip of the needle 12 clears the first and second hooks causing the first and second arms to close and the first and second hooks to surround the tip of the needle 12. After the tip of the needle 12 passes the first and second hooks and the first and second arms move into a closed orientation, the tab 85 disengages the outer sleeve 80 and the inner sleeve 82 may be moved axially further into the outer sleeve 80. A second position can refer to the closed position, whereas the first position can refer to any needle 12 position prior to entering the second position.
As the needle 12 is pulled further, the shaft of the needle slides through the needle shield 78 until a deformation 90, for example a crimp or protrusion formed near the distal end of the needle 12 to increase its diameter, engages the clip base as shown in
Further movement of the needle 12 including the deformation 90 results in the inner sleeve 82 being drawn further into the outer sleeve 80, removing the opposing member 88 from the catheter hub 14 as shown in
In the exemplary embodiment shown in
The needle shield 78 depicted in
In various exemplary embodiments, the clip retainer 94 has a surface that extends so that one of the hooks rests on the clip retainer 94 (not shown) throughout the removal of the needle 12. In this configuration, only a single arm moves from the open orientation to the closed orientation. The use of a single moving arm reduces friction on the needle 12 and helps prevent binding during the needle's withdrawal from the catheter hub 14. In certain embodiments, the needle shield is configured to use a clip with only a single arm, although two arms are beneficial in certain applications to balance the clip and resist tilting of the clip's base relative to the needle 12. The features of the exemplary embodiments of
As the needle 12 is withdrawn into the needle shield 96, the clip 100 moves into a closed position, disengaging the tab 104 from the latch 102 and allowing the latch 102 to open as shown in
As shown in
Any of the needle shields described above can be used in connection with a multi-use, Luer actuated blood control catheter hub as depicted in
The septum 138 further includes a plurality of axial flow channels 139. The flow channels 139 are disposed on an outer circumference of the septum 138. Eight flow channels 139 equidistant from each other are illustrated, although various quantities and positions are contemplated. The flow channels 139 have an appropriate width and depth so that when the septum 138 is not pierced, blood can enter and air can escape the distal end of the septum 138 in the front portion of the catheter hub. At the same time, the flow channels 139 are sized small enough to prevent the blood from exiting past the septum 138 (at least for some period of time). Such a configuration is possible because the intermolecular forces in the blood are greater than the intermolecular forces in air. The septum 138 shown in
An actuator 142 and a biasing or return member, for example a metal or plastic compression spring 144, are positioned in the catheter hub 14. The actuator 142 engages the septum 138 to open the slits 140 and permit fluid flow through the catheter hub 14. The biasing or return member 144 is capable of returning the actuator 142 to a position that allows the resilient slits 140 to close, preventing fluid flow through the catheter hub 14.
The actuator 142 has an actuator barrel 143A surrounding an internal passage 143B. The actuator barrel 143A is a substantially tubular member and the internal passage 143B is substantially cylindrical. The tubular member has one or more openings 143C to permit fluid flow through and around the actuator barrel. A first end of the actuator barrel has a nose with a chamfered outer surface to engage the septum. A frusto-conical section 145A extends from the second end of the actuator barrel 143A. The frusto-conical section 145A has one or more openings 145B to permit fluid flow therethrough. A cylindrical section 145C extends from the frusto-conical section 145A to engage a male Luer connector. One or more hooks having an angled front surface and a slot 147 extend from the actuator barrel 143A.
In the exemplary embodiment shown in
When the Luer connector 146 is removed, the spring 144 removes the actuator 142 from the septum 138, closing the slits 140 and preventing fluid from flowing therethrough. This allows the catheter assembly to be reused through multiple Luer connections, as opposed to a single use catheter where the actuator 142 would remain in the septum 138 after a Luer connector is removed. However, a single-use catheter without the actuator 142 and/or spring 144 can also be used with the needle shields described herein. The features of the exemplary embodiments of
The actuator 254 also includes a plurality of grooves 257 that extend axially along the distal portion of an outer surface of the actuator 254 in a plane parallel to the centerline of the actuator 254. For example, four grooves 257, substantially radially equidistant from each other, can be present along an external surface of the distal portion of the actuator 254, although more or less grooves 257 are contemplated. The grooves 257 can be of varying depths into the actuator 254. The grooves 257 are different from the openings 255 because the grooves 257 do not extend completely through the thickness of the actuator 254.
The openings 255 and the grooves 257 advantageously provide increased area for the fluid to move inside the catheter hub assembly. The increased area advantageously allows for fluid flushing and to prevent coagulation of fluid in the proximal and distal ends of the septum. Additionally, the openings 255 and the plurality of grooves 257 advantageously minimize the stagnation of fluid and allow for greater mixing. The grooves 257 further prevent the septum from sealing on an outside surface of the actuator in operation. By not forming a sealing interface, the fluid is permitted to leak through the septum via the grooves 57 and provide additional flushing.
The actuator 364 includes a plurality of openings 365 that extend through the actuator 364 in a similar manner as described above. The actuator 364 includes two rows of four openings 365 having different sizes and spacing, although various quantities, sizes and spacing of the openings 365 are contemplated. As illustrated, the openings 365 provide more area for fluid flow inside the catheter hub 362, thus achieving similar advantages described above with respect to
When operation of the catheter assembly is complete, the actuator 364 is retracted from the septum 370 via the force exerted by the biasing member 366. The catheter assembly is configured for multiple uses upon depression of the actuator 364. The features described in this embodiment, including the actuator, can be used in combination with the features described throughout this application.
