The subject disclosure relates to sterile bags and/or drapes for equipment used in a medical and/or biological setting. Moreover, the subject disclosure relates to packaging and deployment of sterile bags and drapes in a sterile environment by one person and/or multiple person deployment.
A large number of current medical and biological procedures require a sterile bag or drape to prevent cross contamination between a patient/sample and a device used for the procedure. For elongated devices the bag/drape used is usually a polymer film tube connected to the proximal end of non-sterile portion of the device and extending to at least the end of required sterile field enclosing the device. As a new bag/drape must be deployed for each such procedure the ease and expedience of its deployment is often essential for the efficient work flow.
A first prior art example of a sterile bag/drape for the medical field is taught in U.S. Patent Application Publication No. U.S. No. 2014/0338676 A1, entitled “Medical Drape And Methods Of Covering Equipment With Medical Drapes” to Marinchak. A sterile drape 4 is provided to cover medical equipment 8, 10, 36. The drape 4 may include an expandable element 30 to open the open end of the drape 16. A sheath may also be provided to cover the drape 4 prior to use. The drape 4 may also be held in a container, which may be coupled to the equipment. Furthermore. the drape 4 may include one or more partially deployed positions in which the drape 4 is partially deployed yet the sterile surface of the drape 4 remains unexposed so that the drape 4 may be partially deployed by non-sterile personnel and stored in a non-sterile area.
A second prior art example of sterile bag/drape for the medical field is taught in U.S. Pat. No. 5,792,045, entitled “Sterile Surgical Coupler And Drape” to Adair. An apparatus and method are provided for enclosing a non-sterile camera setup comprising a video camera VC, its trailing cables, and a standard optical connector OC for use of the unsterile camera setup in the sterile environment of an operating room. The apparatus includes a coupler having a first end for attachment to the unsterile camera setup VC. FR. OC and a second end for attachment to a sterile endoscope E. A passageway is formed inside the coupler 10 that extends from the first end to the second end thereof providing an optical pathway whereby an image from the endoscope E may be transmitted to the unsterile camera setup VC, FR. OC. A transparent window is mounted transversely across the passageway between the first and second ends of the coupler providing a sterile barrier therebetween. In operation, a sterile drape 60 is positioned over the first end of the coupler and extends over the unsterile camera setup VC. FR. OC. The sterile drape 60 is secured between the first and second ends of the coupler by a locking ring which secures the distal end of the drape so that a fluid and airtight seal is formed therebetween. A sterile disposable wand may be releasably attached to the second end of the coupler for providing support to the unsterile camera setup VC, FR. OC as it is attached to the coupler 10. The wand may then be detached enabling connection of the sterile endoscope E to the second end of the coupler 10.
A third prior art example of a sterile bag/drape for the medical field is taught in U.S. Pat. No. 8,459,266, entitled “Pleated Bag For Interventional Pullback Systems” to Glynn et al. A system is provided that includes a pullback device, catheter, and pleated bag. Pleated bags 115 are used with interventional pullback systems 5, including imaging catheters such as IVUS catheters, as well as for use with other catheters. An exemplary pleated bag 115 of the system may be an elongate, sterile bag, having a plurality of pleats near the distal end, and including an orifice proximal to the pleats designed to allow passage of a catheter into the bag. The above pleated bag system allows for improved imaging catheter procedures at reduced costs.
A fourth prior art example of a sterile bag/drape used in the medical field is taught in a video uploaded on YouTube.com entitled “P3 medical-Ring-style Camera Drape with elastomeric end section” posted by p3medical (n.d.), and retrieved from link https://www.youtube.com/watch?v=HBENsdvuvpl, herein referred as “P3MEDICAL”. In PSMEDICAL a tube style medical drape is installed on an endoscopic probe. The elastomeric drape is assembled so that it is attached to a ring. The probe is inserted through the ring and then a distally deployed portion of the drape is attached to a proximate end having an attachment coupling. The attachment coupling of the endoscopic probe is then connected to another upstream portion of the medical system. The drape is then unrolled or deployed over the longitudinal length of the upstream portion of the medical system.
One disadvantage to the above prior art is that the bags/drapes are designed for large equipment and methods for covering large medical equipment, as opposed to hand-held devices. See paragraph [0001] of U.S. Patent Application Publication No. U.S. 2014/0338676 A1, entitled “Medical Drape And Methods Of Covering Equipment With Medical Drapes” to Marinchak, for example.
Moreover, as can be observed in the PSMEDICAL video for example, current sterile bag/drape deployment methods are in many cases cumbersome and require coordinated efforts of a sterile and non-sterile person to implement. Hence, typically, multiple personal may be required to deploy complicated drape deployment systems.
And further, despite some advances, such as pre-mounting the sterile bag/drape on the equipment for ease of deployment, sterile drape deployment methods are still in many cases cumbersome, requiring coordinated efforts between at least one sterile and one non-sterile person to implement.
Therefore, a need still exists for improvement and streamlining a process of sterile bag/drape deployment which is simple to use and cost-effective. Ideally, a simple and cost-effective drape system could be deployed by only one person if necessary. Accordingly, in view of these considerations, it would be advantageous to address and/or overcome at least some of the deficiencies described herein above.
Accordingly, it can be beneficial to address and/or overcome at least some of the deficiencies indicated herein above, and thus, to provide a simplified sterile drape contamination prevention drape assembly and method for simplified deployment of the same.
According to various example embodiments of the present disclosure, a simplified sterile bag with packaging and method for a simplified one person deployment of the same is provided for covering an medical instrument or device deployable from a deployment port of a system for deploying the instrument.

According to yet another embodiment of the present disclosure, the attachment means includes adhesive pre-applied to the deployment port attaching end for attaching the bag to the mating portion of the deployment port.
According to still another embodiment of the present disclosure, the attachment means includes a magnetic flange affixed to the deployment port attaching end that magnetically attaches to the mating portion of the deployment port.
And, according to another embodiment of the present disclosure, the attachment means includes a mechanical means for removably attaching the deployment port attaching end of the bag to the mating portion of the deployment port.
According to still another embodiment of the present disclosure, the contamination prevention bag assembly further comprises contamination prevention packaging hermetically sealing at least the outer bag surface in a non-deployed state, wherein the bag is packaged and stored in a folded state.
According to still yet another embodiment of the present disclosure, the contamination prevention packaging includes at least one removable attachment portion covering the deployment port attaching end of the non-deployed drape assembly, and wherein the at least removable portion is configured to be removed before attaching the attachment means to the mating portion of the deployment port.
Additionally, according to yet another embodiment of the present disclosure, the contamination prevention packaging includes at least one removable inner liner covering the deployment port attaching end of the non-deployed drape assembly, and wherein the at least one removable inner liner portion is configured to be removed before attaching the distal portion of the instrument to the distal mating feature configured to receive the distal portion of the instrument.
And, according to still another embodiment of the present disclosure, the contamination prevention packaging includes at least one removable portion covering at least a distal side and a length side of the bag assembly defined by folded edges formed by the folded bag in the non-deployed state, which when removed, uncovers the distal deployment end of the bag assembly and the folded edges of the bag.
Moreover, according to another embodiment of the present disclosure, a method for utilizing a contamination prevention bag assembly for covering an instrument deployable from a system having a deployment port. The bag assembly includes a bag folded in a non-deployed state, the bag including inner an inner and outer surface, a deployment port attaching end, a distal deployment end having a mating feature configured to receive a distal portion of the instrument, and an attachment means disposed on the deployment port attaching end of the bag; and contamination prevention packaging hermetically sealing at least the outer bag surface in a non-deployed state. Here, the method includes attaching the attachment means of the bag assembly to a mating portion of the deployment port; inserting the distal portion of the instrument through the deployment port attaching end of the bag assembly and engaging the distal portion of the instrument into the distal mating feature configured to receive a distal portion of the instrument; removing the contamination prevention packaging hermetically sealing at least the outer bag surface; and deploying the instrument from a non-deployed position to a deployed position through the deployment port and externally distal from the deployment port, wherein the bag is unfolded when the instrument is moved from the non-deployed position to the deployed position externally distal from the deployment port.
As can be understood from the above description the present disclosure allows for simplified sterile bag/drape deployment coincident and combined with the device deployment saving significant portion of operator (and especially sterile operator) time. Accordingly, a simplified sterile bag/drape with packaging and method for simplified deployment of the same by a single operator and/or more than one operator is realized from the present disclosure.

Moreover, in other embodiments, the bag/drape 30 may not have an annular shape, and instead, may have a rectangular, trapezoidal, oval, etc. cross-sectional shape formed to cover various medical system components having different shapes/sizes. As shown in
The bag/drape 30 includes a deployment port attaching end 34 configured to be attached to a mating portion or attachment surface 22 (hereinafter referred to as “mating portion”) of a deployment port 24 that is part of a medical system. The mating portion 22 in
Furthermore, the deployment port 24 may be located elsewhere in a variety of places/positions/structures of the medical system, and is thus, should not be limited to the illustrated position in the disclosure. For example, the location of the mating portion 22 can also be on an internal surface of the housing 20 in another embodiment. Or in an alternative another alternative embodiment, the deployment port 24 may be located in an independent or standalone structure (not illustrated) designed for the sole purpose of supporting the simplified sterile bag 1. Or in other embodiments, the medical instrument 10 may rest on a top or side of a main console of the medical system. Accordingly, the medical instrument 10 does necessarily need to be deployed from the housing 20 of the medical system.
Still referring to
Upon deployment, bag/drape 30 is generally concentrically unfolded about the center z axis when the medical instrument 10 is moved from the non-deployed position to the deployed position. However, it is noted that the deployment of the bag/drape 30 may also include being unfolded in varying directions about various axis (x-axis, y-axis or z-axis) and is not necessarily limited about the center z axis when the medical instrument 10 is moved from the non-deployed position to the deployed position. For example, as shown in

It is further noted that in another embodiment, the inner liner packaging portion 44 does not necessarily have to be removed. That is to say, the medical instrument 10 may be pierced through the inner liner packaging portion 44 so that the medical instrument 10 can be advanced through deployment port 24 with the inner liner packaging portion 44 left in place and not removed. In such embodiment, pre-scored lines may be formed in the inner liner packaging 44 to facilitate appropriate piercing through the inner liner packaging 44 portion.
In Step 100, the simplified sterile bag 1 and packaging assembly 5 is in a folded non-deployed state completely hermetically sealed packaged state. First, the attachment packaging 43 is removed from the deployment port attaching end 34 of the simplified sterile bag 1 before deployment, according to the first example embodiment of the disclosure. The attachment packaging 43 is able to be first removed so that the deployment port attaching end 34 of the simplified sterile bag 1 can be attached to the mating portion 22 of the deployment port 24 while still maintaining/preserving sterile conditions for the simplified sterile bag 1 in an attached folded non-deployed state by a single operator. (See
Next in step 200, the simplified sterile bag 1 and packaging assembly 5 is configured in a folded non-deployed state in which the attachment packaging portion 43 has been removed by a single operator from the deployment port attaching end 34 of the simplified sterile bag 1 and packaging assembly 5 and of which been attached to the mating portion 22 on the deployment port 24 by a single operator, according to the first example embodiment of the disclosure. Here, the attachment packaging 43 is removed and the deployment port attaching end 34 of the simplified sterile bag 1 is attached to the mating portion 22 of the deployment port 24 while still maintaining/preserving sterile conditions for the simplified sterile bag 1 packaging assembly 5 in an attached folded non-deployed state by the single operator. (See
Next in step 300, the simplified sterile bag 1 and packaging assembly 5 is configured in a folded non-deployed state in which the inner liner packaging portion 44 of the packaging has been removed by a single operator from the deployment port attaching end 34 of the packaging assembly 5 before deployment, according to the first example embodiment of the disclosure. The inner liner packaging portion 44 is removed so that the distal portion 14 of the medical instrument 10 may be mated to the mating feature 32 such as an aperture/orifice and/or receptacle configured to receive the distal portion 14 of the medical instrument 10. (See
Next in step 400, the simplified sterile bag 1 and packaging assembly 5 in configured in a folded non-deployed state in which the inner liner packaging portion 44 of the packaging has been removed by a single operator with the medical device 10 positioned internally in the deployment port 24 and mated to the mating feature 32, such as an aperture/orifice/receptacle formed in a distal tip 8 of the simplified sterile bag 1, according to the first example embodiment of the disclosure. At this point in the deployment sequence, the distal tip 14 of the medical instrument 10 is mated by a single operator with the mating feature 32 having the aperture/orifice/receptacle affixed or formed integrally into to the distal deployment end 8 of the bag/drape 30. Since an inner surface of the bag/drape 30 does not have to maintain sterility and will get in contact with a non-sterile medical instrument 10, removal of the inner liner packaging portion 44 of the packaging may be performed by a single non-sterile operator. Furthermore, since the exterior packaging portion 42 is still intact at his point in the deployment sequence, it will aid any medical instrument 10 mating manipulations by the single non-sterile operator with the mating feature 32. (See
Next in step 500, the simplified sterile bag 1 is configured in a folded non-deployed state in which the exterior packaging portion 42 of the packaging has been entirely removed by a non-sterile operator from the simplified sterile bag 1 and with the distal tip 14 of medical instrument 10 being positioned internally in the deployment port 24 and mated by a non-sterile operator to the mating feature 32 formed/integrated into the a distal tip 8 of the simplified sterile bag 1, according to the first example embodiment of the disclosure.
Next in step 600, the medical instrument 10 is ready to be deployed by a sterile operator through the deployment port 24 such that the medical instrument 10 clears the deployment port 24, according to the first example embodiment of the disclosure.
In an alternative method embodiment, if all the above steps are performed by a single operator, the single operator will required sterile cleaning/scrubbing before proceeding with step 600.
As can be understood from the above description, the present disclosure allows for simplified sterile bag/drape 1 deployment coincident and combined with the medical instrument 10 deployment saving significant portion of operator (especially sterile operator) time. The present disclosure allows for simplified sterile bag/drape 1 to be easily deployed by one person and/or by a multiple person team, due to desynchronized actions of sterile and non-sterile operators.
Accordingly, a simplified sterile bag/drape with packaging and method for simplified deployment of the same is realized from the present disclosure wherein the simplified sterile bag 1 may be easily deployed from a medical system by only one person or by a multiple person team, due to desynchronized actions of sterile and non-sterile operators, thereby reducing operating expenses.
Yet in another alternative embodiment, such an instrument/device support 48 may include a linear slide or an articulated arm (not shown) deployable in conjunction with the medical instrument/device 10 inside the simplified sterile bag 1 to provide for additional device support and/or articulation during use.
Moreover, in another alternative embodiment, an additional feature (such as a handle or gripping feature) may be added to an outer sterile surface of the mating feature 32 or elsewhere on the bag assembly 1 to facilitate medical instrument 10 deployment of the simplified sterile drape 1 by a sterile operator during deployment and subsequent handling and manipulating of the medical instrument 10.
While yet in another alternative embodiment, where a sterile probe, such as a cardiovascular imaging catheter, is to be attached to the medical instrument 10, a corresponding opening/receptacle/adaptor may be provided in the distal end 8 of the simplified sterile bag 1 to allow a probe attachment portion to mate with the medical instrument 10 so that each are securely engaged/connected together. The probe attachment portion may be further adapted for convenient grip (as a handle) during deployment and subsequent handling and manipulating of the medical instrument 10.
Or in an alternative method embodiment, the inner liner packaging portion 44 is left in place by the single operator. Instead, the medical instrument 10 is pierced through the inner liner packaging portion 44 so that the medical instrument 10 can be advanced through deployment port 24 with the inner liner packaging portion 44 left in place and not removed. In such embodiment, pre-scored lines may be formed in the inner liner packaging 44 to facilitate appropriate piercing through the inner liner packaging 44 portion.
Or in an alternative method embodiment, the inner liner packaging portion 44 is omitted all together the and the annular bag/drape 30 itself functions as a sterile barrier.
In the embodiment shown in
Additionally, in another alternative embodiment, the simplified sterile bag 1 and packaging assembly 5, may be inserted and retained in place by being installed, after removal of attachment packaging portion 43, into a corresponding sized recess or slot formed in the structure defining the deployment port 24. In this configuration, since no portion of the simplified sterile bag 1 and packaging assembly 5 is yet exposed before removal of attachment packaging portion 43, this step it may be performed by a non-sterile personal.
