Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 63 / 014,684, filed April 23, 2020, the contents of which are incorporated by reference in their entirety.

[0002] SUMMARY The present disclosure relates generally to fecal collection devices and systems for collecting feces released from a user's body and transporting the feces away from the body. [Background technology]

[0003] In various circumstances, a user may have limited or impaired mobility, making normal bowel function and processes difficult (or impossible). For example, some individuals may have impaired mobility due to a physical disability, or may be bedridden due to injury or illness. Also, for example, fecal collection may be required for monitoring purposes, such as to monitor input and output in a clinical environment (e.g., in an intensive care unit or for other clinical and / or laboratory testing).

[0004] Various approaches have been developed to address some of the problems or conditions associated with impaired or restricted bowel processes, however, traditional approaches suffer from their own problems or limitations. Summary of the Invention

[0005] In one example, a feces collection system is described. The feces collection system includes a user interface assembly, a drainage conduit, and a collection reservoir. The user interface assembly includes a user interface and an applicator. The user interface has a proximal side and a distal side. The proximal side is configured to couple to the skin of a user. The applicator is coupled to the distal side of the user interface. The applicator is removable from the user interface while the user interface is coupled to the user. The drainage conduit extends between a proximal end and a distal end. The proximal end is configured to couple to the distal side of the user interface. The drainage conduit defines a lumen configured to direct feces from the proximal end to the distal end. The collection reservoir is coupled to the distal end of the drainage conduit.

[0006] In another example, a method of using a fecal collection system is described. The method includes positioning a user interface assembly at a user's anus. The user interface assembly includes a user interface and an applicator. The method also includes coupling the user interface to the user's skin by using the applicator to press the user interface against the user's skin. The method further includes detaching the applicator from the user interface after coupling the user interface to the user's skin.

[0007] The discussed features, functions, and advantages may be achieved independently in various embodiments or may be combined in yet other embodiments, further details of which can be seen with reference to the following description and drawings.

[0008] The novel features believed characteristic of the illustrative embodiments are set forth in the appended claims.

[0010] The disclosed embodiments will now be described more fully hereinafter with reference to the accompanying drawings, some (but not all) of which are shown. Indeed, several different embodiments may be described, and these should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0011] 1, there is shown an example of a simplified block diagram of a fecal collection system 100. As shown in FIG 1, fecal collection system 100 includes a user interface assembly 110, a drainage conduit 112, and a collection reservoir 114. Fecal collection system 100 can be coupled to a user's skin such that fecal collection system 100 is external to the user's body.

[0012] The user interface assembly 110 includes a user interface 116 and an applicator 118. The user interface 116 has a proximal side and a distal side. The proximal side is configured to couple to the skin of a user. For example, the user interface 116 can include an adhesive sheet 120 on the proximal side. As an example, the adhesive sheet 120 can include a biocompatible adhesive, such as, for example, a silicone adhesive, that can enable coupling of the user interface 116 to the skin of a user. In one example, the adhesive sheet 120 can be configured to couple the user interface 116 to the skin of a user for a period of at least 8 hours prior to removal and / or replacement. In another example, the adhesive sheet 120 can be configured to couple the user interface 116 to the skin of a user for a period of about 12 to 72 hours prior to removal and / or replacement.

[0013] The applicator 118 is coupled to a distal side of the user interface 116. The applicator 118 is removable from the user interface 116 while the user interface 116 is coupled to a user. In this arrangement, the applicator 118 aids in coupling of the user's skin to the user interface 116 and can then be removed to allow coupling of the drainage conduit 112 to the user interface 116 and / or to reduce the amount of material in the fecal collection system between the user and a support structure (e.g., a hospital bed and / or a wheelchair). Removal of the applicator 118 can be useful in reducing the risk of bed sores.

[0014] The drainage conduit 112 extends between a proximal end and a distal end. In one example, the proximal end of the drainage conduit 112 can be securely coupled to a distal side of the user interface 116 before the applicator 118 is detached from the user interface 116. In this example, the drainage conduit 112 can be coupled to the user interface 116 while the user interface 116 is coupled to the skin of the user. In another example, the proximal end is configured to couple to a distal side of the user interface 116 after the applicator 118 is detached from the user interface 116. More generally, the drainage conduit 112 defines a lumen configured to direct feces from the proximal end to the distal end. The collection reservoir 114 is coupled to the distal end of the drainage conduit 112. The collection reservoir 114 is configured to contain feces.

[0015] The drainage conduit 112 and lumen can have an elongated shape. In one example, the drainage conduit 112 can have a length of about 4 feet to about 6 feet. This length can be useful for positioning the collection reservoir 114 in a location that is remote from a user (e.g., the side of a patient support structure such as a hospital bed). However, the drainage conduit 112 can have a different length in other examples.

[0016] Further, in some examples, the drainage conduit 112 can be configured to direct feces from the proximal end to the distal end in response to squeezing the drainage conduit 112 toward the collection reservoir 114 (e.g., by applying compression to the drainage conduit 112 along the length of the drainage conduit 112 in a proximal to distal direction). For example, the drainage conduit 112 can have at least one of a hardness and a flexibility that facilitates manually squeezing the feces toward the collection reservoir 114. Also by way of example, the drainage conduit 112 can be formed from at least one of polyurethane (PU) and polyvinyl chloride (PVC). For example, the drainage conduit 112 can be a film tube having a thickness between about 2 mils and about 4 mils.

[0017] In some embodiments, the drainage conduit 112 can be at least partially transparent or translucent. This can be useful in determining whether feces is present in the drainage conduit 112 so that a decision can be made to squeeze the drainage conduit 112 and force the feces into the collection reservoir 114.

[0018] In an alternative example, fecal collection system 100 can omit drainage conduit 112, such that collection reservoir 114 is directly coupled to user interface 116. This can reduce manufacturing costs and reduce the need to squeeze drainage conduit 112. However, collection reservoir 114 is positioned closer to the user, which increases the volume of the device that may come into contact with the user and makes replacement of collection reservoir 114 more difficult.

[0019] As discussed above, the user interface 116 can include an adhesive sheet 120. The adhesive sheet 120 can define an aperture in communication with the lumen of the drainage conduit 112. In this arrangement, feces can flow from the user's anus through the aperture in the adhesive sheet 120 and into the drainage conduit 112. The drainage conduit 112 can then direct the feces to the collection reservoir 114.

[0020] In one example, the apertures in adhesive sheet 120 can have a diameter of about 1.5 inches. This can be useful to provide an opening large enough to accommodate feces within drainage conduit 112, while still allowing the surface area of ​​adhesive sheet 120 to secure feces collection system 100 to the user's skin. In another example, the apertures in adhesive sheet 120 can have a diameter of about 1 inch to about 2 inches.

[0021] In some embodiments, the user interface 116 may also include a collar 122 extending distally from the adhesive sheet 120. As discussed above, the adhesive sheet 120 may include an adhesive (e.g., a silicone adhesive, etc.) capable of coupling the user interface 116 to the skin of a user. The proximal end of the drainage conduit 112 may be coupled to the collar 122 of the user interface 116. For example, the collar 122 may be a foam wedge that is receivable at the proximal end of the drainage conduit 112. Thus, in this example, the collar 122 may be coupled to the drainage conduit 112 by a friction fit connection. However, in other examples, the collar 122 may additionally or alternatively be coupled to the drainage conduit 112 by at least one of a threaded connection, a hook and loop connection, and an adhesive connection.

[0022] More generally, the collar 122 may be configured to allow at least one of coupling, decoupling, and recoupling of the user interface 116 and one or more drainage conduits 112. Thus, the collar 122 may allow replacement of at least one of the drainage conduits 112 and the collection reservoir 114 without removing the user interface 116 from the user. For example, a method of using the fecal collection system 100 may include detaching a first drainage conduit 112 from the user interface 116 after an initial period of use (e.g., about 8 hours), and then coupling a second drainage conduit 112 to the user interface 116.

[0023] In one example, the collar 122 can define a first aperture in communication with the lumen of the drainage conduit 112, and the adhesive sheet 120 can define a second aperture axially aligned with the first aperture of the collar 122. In this arrangement, feces can flow from the user's anus into the drainage conduit 112 through the first aperture of the collar 122 and the second aperture of the adhesive sheet 120. The drainage conduit 112 can then direct the feces to the collection reservoir 114.

[0024] In one example, the first aperture and the second aperture can have a diameter of about 1.5 inches. This can be useful to provide an opening large enough to accommodate feces within the drainage conduit 112 while still allowing the surface area of ​​the adhesive sheet 120 to secure the feces collection system 100 to the user's skin. In another example, at least one of the first aperture and the second aperture can have a diameter of about 1 inch to about 2 inches.

[0025] In one example, fecal collection system 100 may also include a first check valve 124 within the lumen defined by drainage conduit 112. First check valve 124 is configured to allow feces to flow in a direction from the proximal end to the distal end of drainage conduit 112 and to prevent feces from flowing in a direction from the distal end to the proximal end of drainage conduit 112. This may be useful in preventing feces from passing back toward and coming into contact with the user's skin.

[0026] In one example, the first check valve 124 can be configured to transition from a closed state to an open state in response to feces passing through the first check valve 124 in a distal direction (e.g., from the user toward the drainage conduit 112). In the closed state, the first check valve 124 can block the backflow of feces in a proximal direction toward the user (e.g., toward the user interface assembly 110). In the open state, the first check valve 124 can expand to define an enlarged passage that allows feces to pass through the first check valve 124 in a distal direction. In one embodiment, the first check valve 124 can be configured to expand to have a diameter approximately equal to the diameter of the drainage conduit 112. For example, in an embodiment in which the drainage conduit 112 has a diameter of approximately 1.5 inches, the first check valve 124 can expand from a diameter of approximately zero inches in the closed state to a diameter of approximately 1.5 inches in the open state.

[0027] In one example embodiment, the first check valve 124 can include multiple flaps extending distally from the proximal end of the drainage conduit 112 (e.g., at the apertures of the adhesive sheet 120). In this arrangement, the flaps can taper toward each other along the length of the flaps in a direction from the proximal end of the drainage conduit 112 toward the distal end of the drainage conduit 112. In one example, the material of the flaps can be the same as the material of the drainage conduit 112. The flaps can be monolithic (e.g., one piece) with the drainage conduit 112, or the flaps can be separate structures that are joined (e.g., by welding) to the drainage conduit 112.

[0028] The collection reservoir 114 may additionally or alternatively include a second check valve 126 configured to allow feces to flow from the drainage conduit 112 to the collection reservoir 114 and to prevent feces from flowing from the collection reservoir 114 to the drainage conduit 112. This may also be useful in preventing feces from passing back toward and coming into contact with the user's skin. In one example, the drainage conduit 112 may have a diameter at the distal end 212B of about 1 inch to about 3 inches.

[0029] FIG 2 illustrates an example of an implementation of fecal collection system 100. As shown in FIG 2, fecal collection system 100 includes a user interface assembly 110, a drainage conduit 112, and a collection reservoir 114, as described above. As described above, user interface assembly 110 includes a user interface 116 having a proximal side 216A and a distal side 216B. Further, in FIG 2, drainage conduit 112 extends between a proximal end 212A and a distal end 212B.

[0030] As shown in FIG. 2, the drainage conduit 112 can be configured to be coupled, detached, and recoupled to the collection reservoir 114. This may allow a first collection reservoir 114 containing feces to be detached and a second collection reservoir 114 that is empty to be coupled to continue collecting feces without having to detach at least one of the user interface 116 and the drainage conduit 112 from the user's skin. In some examples, the drainage conduit 112 and the collection reservoir 114 can be coupled, detached, and recoupled to the user interface 116 while the user interface 116 remains coupled to the user's skin. This may allow for the modification of at least one of the drainage conduit 112 and the collection reservoir 114 without removing the user interface 116 from the user. In other examples, the drainage conduit 112 can be permanently fixed to the collection reservoir 114. This can be useful in reducing the risk of leakage at the interface between the user interface 116 and the drain conduit 112.

[0031] 2, the collection reservoir 114 can include a measurement window 230 that includes a plurality of volume markings 232. The measurement window 230 can be transparent and / or translucent such that the amount of feces in the collection reservoir 114 can be visually observed. This can provide an indication as to when to replace the collection reservoir 114, when to collect a sufficient volume of feces to provide a sample for diagnostic evaluation, or both.

[0032] 2, the first check valve 124 is positioned at the proximal end 214 A. In other examples, the first check valve 124 can be positioned between the proximal end 214 A and the distal end 214 B of the drainage conduit 112.

[0033] 3A-3D illustrate a process for coupling user interface assembly 110 to a user's skin, according to one example embodiment of user interface assembly 110. As shown in FIGS. 3A-3D, user interface assembly 110 includes a user interface 116 and an applicator 118. In FIG. 3A, user interface assembly 110 is positioned at a user's anus 340. User interface assembly 110 is folded such that a proximal side 216A of user interface 116 faces outward and a distal side 216B of user interface 116 faces inward.

[0034] In FIG. 3B, the applicator 118 is used to press the proximal side 216A of the user interface 116 against the skin 342 of the user. In this example, the applicator 118 includes a first outer portion 318A and a second outer portion 318B that are hingedly movable relative to one another. For example, the applicator 118 can include a hinge portion 318C between the first outer portion 318A and the second outer portion 318B. In this example, the hinge portion 318C is perforated to aid in removing the applicator 118 from the user interface 116. As shown in FIG. 3B, the first outer portion 318A of the applicator 118 and the second outer portion 318B of the applicator 118 can move relative to one another to press the user interface 116 against the skin 342 of the user.

[0035] In FIG. 3C, applicator 118 has been removed from user interface 116. For example, applicator 118 can be removed from user interface 116 by separating outer portion 318A and second outer portion 318B from user interface 116 along the perforation line of hinge portion 318C. As shown in FIGS. 3C-3D, removing applicator 118 can expose collar 122 of user interface 116. In FIG. 3D, user interface 116 is coupled to a user's skin 342. As shown in FIG. 3D, adhesive sheet 120 is coupled to skin 342, with collar 122 extending distally from adhesive sheet 120. Similarly, in FIG. 3D, the collar 122 defines a first aperture 344 and the adhesive sheet 120 defines a second aperture 346, with the first aperture 344 and the second aperture 346 aligned with the user's anus 340.

[0036] Figure 4 shows an example of the proximal side 216A of the user interface 116. In Figure 4, the user interface 116 includes a release liner 448 that covers the adhesive on the proximal side 216A of the user interface 116. The release liner 448 can be removed to expose the adhesive prior to bonding the user interface 116 to a user's skin.

[0037] FIG. 5 shows the drain conduit 112 and collection reservoir 114 according to one example embodiment.

[0038] 6, fecal collection system 600 is shown as another example of an embodiment of fecal collection system 100. As shown in FIG. 6, fecal collection system 600 includes user interface assembly 110, drainage conduit 112, and collection reservoir 114, as described above. As described above, user interface assembly 110 includes user interface 116 having proximal and distal sides. Further, in FIG. 6, drainage conduit 112 extends between proximal end 612A and distal end 612B.

[0039] As shown in FIG. 6, the drainage conduit 112 can be configured to be coupled, detached, and recoupled to the collection reservoir 114. This may allow a first collection reservoir 114 containing feces to be detached and a second collection reservoir 114 that is empty to be coupled to continue collecting feces without having to detach the user interface 116 from the user's skin. In other examples, the drainage conduit 112 can be permanently fixed to the collection reservoir 114. In such examples, the drainage conduit 112 and collection reservoir 114 can be coupled, detached, and recoupled to the user interface 116 while the user interface 116 remains coupled to the user's skin (e.g., in other examples, the user interface 116 can further include a collar 122, described above).

[0040] 6, the distal end 612B of the drainage conduit 112 includes a male quick connect coupler 650A that can be coupled to a female quick connect coupler 650B of the collection reservoir 114. The female quick connect coupler 650B of the collection reservoir 114 further includes an actuator 650C (e.g., a button) that is operable to at least one of couple and decouple the male quick connect coupler 650A and the female quick connect coupler 650B. In this arrangement, the drainage conduit 112 can remain securely coupled to the collection reservoir 114 until the actuator 650C operates to decouple the male quick connect coupler 650A of the drainage conduit 112 from the female quick connect coupler 650B of the collection reservoir 114. This can be useful to inhibit (or prevent) inadvertent disconnection of the drainage conduit 112 and the collection reservoir 114. In FIG. 6, the drain conduit 112 includes a male quick connect coupler 650A and the collection reservoir 114 includes a female quick connect coupler 650B, however, in alternative examples, the drain conduit 112 can include a female quick connect coupler 650B and the collection reservoir 114 can include a male quick connect coupler 650A.

[0041] Additionally, as discussed above, the collection reservoir 114 may include a measurement window that includes a plurality of volume markings (similar to the collection reservoirs shown in Figures 2 and 5). The measurement window may be transparent and / or translucent, such that the amount of feces in the collection reservoir may be visually observed. This may provide an indication as to when to replace the collection reservoir, when a sufficient volume of feces has been collected to provide a sample for diagnostic evaluation, or both.

[0042] 6, the proximal end 612A of the drainage conduit 112 is coupled to a distal side of the user interface 116. In this example, the drainage conduit 112 can be non-removably coupled (e.g., fixedly and permanently coupled) to the user interface 116. For example, the proximal end 612A of the drainage conduit 112 can be welded to the adhesive sheet 120 at an aperture 646 in the adhesive sheet 120.

[0043] FIG. 7 illustrates an applicator 118 according to the example shown in FIG. 6. As shown in FIG. 7, the applicator 118 includes a first outer portion 718A, a second outer portion 718B, and a hinge portion 718C between the first outer portion 718A and the second outer portion 718B. In this arrangement, the first outer portion 718A and the second outer portion 718B are configured to move about the hinge portion 718C between an unfolded state (shown in FIG. 7) and a folded state (shown in FIGS. 8A-8B). As described below, the folded state can be useful for inserting the applicator 118 and the user interface 116 between the buttocks to access the user's anus. The unfolded state can be useful for removing the applicator 118 from the user interface 116, as described above.

[0044] The hinge portion 718C is further configured to facilitate removal of the applicator 118 from the user interface 116. For example, in FIG. 7, the hinge portion 718C includes a first bridge portion 752A and a second bridge portion 752B, connecting the first outer portion 718A of the applicator 118 to the second outer portion 718B of the applicator 118 (e.g., the first outer portion 718A and the second outer portion 718B can be coupled to each other only at the first bridge portion 752A and the second bridge portion 752B). The first bridge portion 752A and the second bridge portion 752B can have a relatively small size compared to the overall size of the applicator 118 in a dimension extending along an intersection between the first outer portion 718A and the second outer portion 718B. For example, the combined length of the first bridge portion 752A and the second bridge portion 752B can be less than about 50 percent of the overall length of the applicator 118 in this dimension. This relative size can (i) prevent inadvertent separation of the first outer portion 718A and the second outer portion 718B during coupling of the user interface 116 to a user, and (ii) allow the first outer portion 718A and the second outer portion 718B to be easily pulled away from one another after coupling the user interface 116 to a user.

[0045] In some embodiments, the first bridge portion 752A and the second bridge portion 752B can include perforations to facilitate separation of the first outer portion 718A and the second outer portion 718B. The perforations can allow the combined length of the first bridge portion 752A and the second bridge portion 752B to be greater than about 50 percent of the overall length of the applicator 118 in a dimension extending along the intersection between the first outer portion 718A and the second outer portion 718B (e.g., along the hinge portion 718C).

[0046] 7, the drainage conduit 112 extends through an aperture 754 in the applicator 118. A first bridge portion 752A is defined between the aperture 754 and a slit 756. The slit 756 extends along a hinge portion 718C between the first and second outer portions 718A, 718B of the applicator 118. The slit 756 can be useful for reducing the size of the first bridge portion 752A relative to the overall size of the applicator 118 along the interface between the first and second outer portions 718A, 718B. The slit 756 can additionally or alternatively be useful for increasing the movement of the first and second outer portions 718A, 718B about the hinge portion 718C.

[0047] In one example, the slit 756 can have a length in a dimension extending along the hinge portion 718C (e.g., through the first bridge portion 752A, the aperture 754, and the second bridge portion 752B) that is greater than about 40 percent of the overall length of the applicator 118. This can be useful in achieving the functions of the slit 756 described above.

[0048] The second bridge portion 752B can be defined between an aperture 754 (e.g., at a point opposite the first bridge portion 752A) and the outer periphery of the applicator 118 at the hinge portion 718C. As shown in FIG. 7, the aperture 754 can be offset from the center of the applicator 118. More specifically, the aperture 754 can be closer to a lower edge of the applicator 118 than to an upper edge of the applicator 118. Thus, the proximal end of the drainage conduit 112 can be coupled to the user interface 116 at a position offset below the center of the user interface 116. This can be useful for affixing the user interface 116 to a user's anus, which is typically located below the center of the user's buttocks.

[0049] 7, applicator 118 may further include a first tab 758A on an outer periphery of first outer portion 718A and a second tab 758B on an outer periphery of second outer portion 718B. The first tab 758A and the second tab 758B may extend laterally beyond the outer periphery of user interface 116 such that the first tab 758A and the second tab 758B may facilitate gripping and manipulation of applicator 118 when positioning user interface assembly 110 between a user's buttocks.

[0050] 8A-8B show the user interface 116 and the applicator 118 in a folded state in which the first outer portion 718A and the second outer portion 718B are folded about the hinge portion 718C and the user interface 116 is positioned outside the applicator 118. As shown in FIG. 8A, the applicator 118 can have a size larger than the user interface 116 (e.g., the first tab 758A and the second tab 758B can extend beyond the outer periphery of the user interface 116). This can be useful to provide access to the applicator 118. In another example, the applicator can have a size approximately equal to the size of the user interface 116. More generally, the user interface 116 and the applicator 118 can be configured to allow the user interface 116 and the applicator 118 to be held in one hand while the user interface 116 and the applicator 118 are in the folded state.

[0051] 8A-8B, user interface 116 includes adhesive sheet 120 (shown in FIG. 8B), a first release liner 860, and a second release liner (not shown in FIG. 8A-8B). First release liner 860 is removably coupled to a first half of adhesive sheet 120 (e.g., on one side of hinge portion 718C and aperture 754 in FIG. 8A-8B), and second release liner is removably coupled to a second half of adhesive sheet 120 (e.g., on the other side of hinge portion 718C and aperture 754 in FIG. 8A-8B). In this arrangement, first release liner 860 and second release liner can be independently removed from adhesive sheet 120 to allow coupling of user interface 116 to a user's skin one side at a time.

[0052] The first release liner 860 can include a first portion 860A and a second portion 860B. The first portion 860A can cover a first half of the adhesive sheet 120 to prevent the adhesive sheet 120 from prematurely or inadvertently adhering to an object prior to application of the user interface 116 to the user. The second portion 860B can have a first end that is coupled to the first portion 860A at an inner portion of the user interface 116 (e.g., at the aperture 754) and a second end that is spaced apart from the first portion 860A at an outer portion of the user interface 116 (e.g., at the outer periphery of the user interface 116). In this arrangement, a practitioner can grasp the second end at the periphery of the user interface 116 and pull it outwardly away from the user to separate the first portion 860A of the first release liner 860 from the adhesive sheet 120. Thus, the first release liner 860 can gradually expose a first half of the adhesive sheet 120 in a direction from the aperture 754 toward the outer periphery of the user interface 116. This can be useful for improving bonding of the adhesive sheet 120 to a user's buttocks with the aperture 754 aligned with the user's anus.

[0053] Although not shown in FIGS. 8A-8B, a second release liner can be disposed in a similar manner with respect to the second half of the adhesive sheet 120. The second release liner can thus include a first portion and a second portion. The first portion of the second release liner can cover the second half of the adhesive sheet 120 to prevent premature or inadvertent adhesion of the adhesive sheet 120 to an object prior to application of the user interface 116 to the user. The second portion can have a first end that is joined to the first portion at an inner portion of the user interface 116 (e.g., at the aperture 754) and a second end that is spaced apart from the first portion at an outer portion of the user interface 116 (e.g., at the outer periphery of the user interface 116). In this arrangement, a practitioner can grasp the second end at the periphery of the user interface 116 and pull it outwardly away from the user to separate the first portion of the second release liner from the adhesive sheet 120. Thus, the second release liner can gradually expose the second half of the adhesive sheet 120 in a direction from the aperture 754 toward the outer periphery of the user interface 116. This can be useful to improve bonding of the adhesive sheet 120 to the user's buttocks with the aperture 754 aligned with the user's anus.

[0054] As shown in FIG. 8B, the first and second halves of the adhesive sheet 120 can each include a gripping area 864. The gripping area 864 is located on the periphery of the adhesive sheet 120 and can omit adhesive. This can allow a practitioner to hold the gripping area 864 to manipulate and handle the adhesive sheet 120 while applying the adhesive sheet 120 to the user's buttocks. The gripping area 864 can also facilitate easier removal of the adhesive sheet 120 from the user as compared to alternative embodiments in which the adhesive extends across the entire surface area of ​​the adhesive sheet 120.

[0055] Additionally, as shown in FIGURE 8B, at least one of the user interface 116 and the applicator 118 may include an alignment indicator 866 that may be useful in aligning the aperture 754 and the drainage conduit 112 with the user's anus. For example, in FIGURE 8B, the alignment indicator 866 includes a first line that extends on the applicator 118 from the top of the aperture 754 to the outer periphery of the adhesive sheet 120, and a second line that extends on the applicator 118 from the bottom of the aperture 754 to the outer periphery of the adhesive sheet 120. In this arrangement, the alignment indicator 866 may provide a visual indication of the location of the aperture 754, 646 and the drainage conduit 112 positioned between the buttocks, even if the aperture 754 of the applicator 118 and the aperture 646 of the user interface 116 (shown in FIGURE 6) cannot be directly visualized.

[0056] 9A-9J, a process for coupling a fecal collection system 600 is shown in accordance with one example embodiment of a user interface assembly 110. In FIG. 9A, the user interface assembly 110 is inserted between the buttocks of a user. For example, in the folded state of the applicator 118, a medical practitioner can hold the first tab 758A and the second tab 758B of the applicator 118 together with the gripping area 864 of the adhesive sheet 112. As shown in FIG. 9A, this allows the medical practitioner to hold the user interface assembly 110 in a location remote from the buttocks while positioning the aperture and drainage conduit 112 of the user interface 116 at the anus.

[0057] 9B, the first release liner 860 is removed from the first half of the adhesive sheet 120. For example, a medical practitioner can grasp the peripheral second end of the user interface 116 and pull it outwardly away from the user to separate the first portion 860A of the first release liner 860 from the adhesive sheet 120. In this manner, the first release liner 860 can gradually expose the first half of the adhesive sheet 120 in a direction from the aperture 754 toward the outer periphery of the user interface 116.

[0058] 9C, after the first release liner 860 is removed from the adhesive sheet 120, the medical practitioner can use the alignment indicator 866 to determine the position of the aperture relative to the user's anus. In some instances, the medical practitioner can use the applicator 118 to adjust the position of the user interface 116 relative to the user based on the position of the alignment indicator relative to the user's anus.

[0059] In Figure 9D, the first half 920A of the adhesive sheet 120 can be coupled to the user's skin on the first buttocks. Additionally, as shown in Figure 9D, the medical practitioner can use one hand to place the first half 920A of the adhesive sheet 120 on the first buttocks (e.g., by holding the gripping area 864 of the adhesive sheet 120) while using the other hand to hold the applicator 118 at the anal position.

[0060] 9E, the second release liner 960 is removed from the second half of the adhesive sheet 120. For example, a medical practitioner can grasp the second peripheral end of the user interface 116 and pull it outwardly away from the user to separate the first portion 960A of the second release liner 960 from the adhesive sheet 120. In this manner, the second release liner 960 can gradually expose the second half of the adhesive sheet 120 in a direction from the aperture 754 toward the outer periphery of the user interface 116.

[0061] In Figure 9F, the second half 920B of the adhesive sheet 120 can be coupled to the user's skin on the second buttocks. Additionally, as shown in Figure 9F, the medical practitioner can use one hand to place the second half 920B of the adhesive sheet 120 on the second buttocks (e.g., by holding the gripping area 864 of the adhesive sheet 120) while using the other hand to hold the applicator 118 in place at the anus.

[0062] FIG. 9G illustrates the applicator 118 being removed from the user interface 116, and FIG. 9H illustrates the user interface 116 and the drainage conduit 112 after the applicator 118 has been removed from the user interface 116. For example, as shown in FIG. 9G, the first outer portion 718A and the second outer portion 718B can be torn away from one another (e.g., at at least one of the first bridge portion 752A and the second bridge portion 752B). This can facilitate complete removal of the applicator 118, which can be useful for improving user comfort and reducing pressure on the user's buttocks. However, in another example, the applicator 118 can be detached from the remaining portions of the user interface 116 (e.g., the adhesive sheet 120 and the collar 122) and then moved distally along the drainage conduit 112 away from the user (e.g., with the first bridge portion 752A and the second bridge portion 752B remaining intact). Figures 9I-9J show that the distal end 612B of the drainage conduit 112 is coupled to a collection reservoir 114. As shown in Figures 9I-9J, the collection reservoir 114 can be coupled to a side of a patient support structure (e.g., a hospital bed).

[0063] Applicator 118 includes first outer portion 318A, 718A and second outer portion 318B, 718B in Figures 3A-9J, but can have different configurations in other examples. Figures 10A-13B show embodiments of user interface 116 and / or applicator 118 according to several other examples.

[0064] 10A-10B show a user interface 1016 for another example embodiment of the user interface 116. As shown in FIGS. 10A-10B, the user interface 1016 can include an adhesive sheet 1020, a release liner 1060, and an aperture 1046 in the adhesive sheet 1020. The adhesive sheet 1020 is substantially the same or identical to the adhesive sheet 120 described above, except that the adhesive sheet 1020 in FIGS. 10A-10B can have a different shape. For example, in FIGS. 10A-10B, the adhesive sheet 1020 can include a plurality of arms extending outwardly from a central portion. The central portion of the adhesive sheet 1020 can define the aperture 1046.

[0065] Additionally, the user interface 1016 includes a sacral pressure pad 1068. The sacral pressure pad 1068 can extend from a top edge of the adhesive sheet 1020 such that the sacral pressure pad 1068 is configured to be placed adjacent to the user's sacral region when the adhesive sheet 1020 is coupled to the user's skin with the aperture 1046 aligned with the user's anus. The sacral pressure pad 1068 can have a thickness and flexibility that facilitates reducing pressure on the sacral region when the sacral pressure pad 1068 is positioned between the user's sacral region and a support surface (e.g., a hospital bed and / or a wheelchair).

[0066] In some instances, the sacral pressure pad 1068 may include an adhesive configured to attach the sacral pressure pad 1068 to the sacral region of a user. In such instances, the release liner 1060 may include a sacral portion that covers the adhesive on the sacral pressure pad 1068 prior to attachment of the sacral pressure pad 1068 to the user.

[0067] Similar to the first and second release liners described above, the sacral portion of the release liner 1060 can include a first portion 1060A and a second portion 1060B. The first portion 1060A can cover the adhesive on the sacral pressure pad 1068 to prevent the adhesive from prematurely or inadvertently adhering to an object prior to application of the user interface 116 to a user. The second portion 1060B can have a first end coupled to the first portion 1060A at an inner portion of the sacral pressure pad 1068 (e.g., at an end closest to the adhesive sheet 1020) and a second end separate from the first portion 1060A at an outer portion of the sacral pressure pad 1068 (e.g., at an end furthest from the adhesive sheet 1020). In this arrangement, a practitioner can grasp the second end of the second portion 1060B and pull it outwardly away from the user and the adhesive sheet 1020 to separate the first portion 1060A of the release liner 1060 from the adhesive on the sacral pressure pad 1068. In this manner, the release liner 1060 can gradually expose the adhesive on the sacral pressure pad 1068 in a direction from the adhesive sheet 1020 towards the outer periphery of the user interface 1016. This can be useful for improving adhesion of the adhesive to the sacrum.

[0068] 11A-11B show a user interface 1116 for another example embodiment of the user interface 116. As shown in FIGS. 11A-11B, the user interface 1116 can include an adhesive sheet 1120, a release liner 1160, an aperture 1146 in the adhesive sheet 1120, and a sacral pressure pad 1168. However, in this example, the sacral pressure pad 1168 includes a number of slits 1169. The slits 1169 in the sacral pressure pad 1168 can help spread the sacral pressure pad 1168 over the sacrum of the user and can facilitate removal of the sacral pressure pad 1168 from the user. These functions can be further enhanced by positioning the slits 1169 in an oblique orientation relative to the longitudinal axis of the sacral pressure pad 1168.

[0069] 12A-12C show a user interface assembly 1210 including a user interface 1216 and an applicator 1218. User interface 1216 and applicator 1218 relate to alternative embodiments of user interface 116 and applicator 118, respectively. In FIGURES 12A-12C, user interface 1216 is disposed within aperture 1219 of applicator 1218 during coupling of user interface 1216 to a user, and applicator 1218 and user interface 1216 are configured to be decoupled from one another after coupling user interface 1216 to a user.

[0070] In this example, the user interface 1216 defines an aperture 1246 configured to communicate with the lumen of the drainage conduit 112, as described above. As shown in FIG. 12B, the user interface 1216 can also include an adhesive sheet 1220 and a release liner 1260, as described above.

[0071] 12A and 12C show the user interface assembly 1210 in a first configuration in which the user interface 1216 is housed within an aperture 1219 of the applicator 1218. As shown in FIG. 12C, the user interface assembly 1210 is configured to at least one of bend and fold along an axis extending through the user interface 1216 without detaching the user interface 1216 from the applicator 1218. In this first configuration, an operator can hold the applicator 1218 while having a user couple the user interface 1216 in a manner similar to that described above.

[0072] 12B illustrates the user interface assembly 1210 in a second configuration in which the user interface 1216 is detached from the applicator 1218. In one example, the adhesive 1210 can have a first peel force that defines the amount of force required to remove the user interface 1216 from the user's skin, and the user interface assembly 1210 can have a second peel force that defines the amount of force required to detach the applicator 1218 from the user interface 1216 along the interface between the applicator 1218 and the user interface 1216 (e.g., along the circumference of the aperture 1219). The first peel force can be greater than the second peel force. In this arrangement, once the user interface 1216 is coupled to the user's skin, an operator can detach and remove the applicator 1218 by pulling the applicator 1218 away from the user interface 1216 with a force that is (i) greater than the second peel force and (ii) less than the first peel force.

[0073] 13A-13B show a user interface assembly 1310 including a user interface 1316 and an applicator 1318, which relate to alternative embodiments of the user interface 116 and the applicator 118, respectively. The user interface assembly 1310 is substantially similar to the user interface assembly 1210 of FIGS. 12A-12C, except for the user interface 1316 having multiple arms extending from a central ring that defines an aperture 1346 for communicating with the lumen of the drainage conduit 112.

[0074] Similar to the user interface assembly 1210 of FIGS. 12A-12C, the user interface 1316 is disposed within an aperture 1319 in the applicator 1318 during coupling of the user interface 1316 to a user, and the applicator 1318 and the user interface 1316 are configured to be detached from one another after coupling the user interface 1316 to a user. However, the user interface assembly 1310 of FIGS. 13A-13B differs from the user interface assembly 1210 in that the arms of the user interface 1316, when in the first configuration, extend beyond the aperture 1346 and are coupled to a distal side of the applicator 1318. After coupling the adhesive sheet 1320 on the central ring of the user interface 1316 to the user's skin, the applicator 1318 can be pulled away from the user interface 1316 by a force between the first and second peel forces described above to detach the applicator 1318 from the user interface 1316. In this example, the arm can pass through an aperture 1319 in the applicator 1318 during separation of the applicator 1318 from the user interface 1316 .

[0075] 14-20 show additional views of the example applicator 118 shown in FIGS. 6-9G.
