Description

[Technical field]

[0001] SUMMARY OF THE DISCLOSURE Embodiments of the present invention relate to a valve for an ostomy or urostomy appliance. [Background technology]

[0002] Ostomy appliances are well known in the art. They are typically attached to a user via an adhesive member that extends around the user's stoma, which has an adhesive, and provide a collection volume to collect waste (mainly liquid waste) exiting the stoma. A mechanism for draining the collection volume is often provided. Typically these are in the form of a tap, allowing the user to remove and empty the waste collected in the collection volume without having to remove and discard the entire appliance.

[Figure 9] FIG. 1 is a perspective view of a valve for an ostomy appliance. [Figure 10] FIG. 2 is another perspective partial view of the ostomy appliance. [Figure 11] FIG. 2 is a perspective partial view of an ostomy appliance and a connected drainage tube. [Figure 12A-12B] 12A and 12B show a valve for an ostomy appliance (FIG. 12B is partially cut away). [Figure 13A-13B] 1 shows a valve for an ostomy appliance.

[0009] Referring to the figures, there is shown an ostomy appliance 10 (appliance 10). The ostomy appliance 10 has an attachment member (not shown) for attaching the appliance 10 to a user and includes a first wall 12 defining a stoma-receiving opening for fitting around the user's stoma. A second wall 14 is connected to the periphery of the first wall 12 about its periphery to form a collection volume (for receiving waste from the stoma) between the first wall 12 and the second wall 14.

[0010] The ostomy appliance 10 further includes an outlet portion 20. The outlet portion 20 is formed from a first outlet wall 22 and a second outlet wall 24. The first outlet wall 22 and the second outlet wall 24 are connected along a periphery to form a tube / conduit. It should be understood that the outlet portion 20 may be formed from the same sheet as the extension / first wall 12 and second wall 14.

[0011] The appliance 10 also includes a valve 100 that provides an outlet 102. The valve 100 is connected to the outlet portion 20. Thus, the outlet portion 20 and the valve 100 provide a flow path between the collection volume and the outlet 102. In other words, the outlet portion 20 forms a conduit between the collection volume and the valve 100. Waste flowing from the collection volume passes through the outlet portion 20, then through the valve 100, and exits the appliance 10 via the outlet 102.

[0012] The ostomy appliance 10 is specifically a urostomy or ileostomy appliance that is configured to accommodate a higher percentage of liquid waste than other ostomy appliances. Therefore, the valve 100 must be capable of preventing liquid from exiting the appliance 10 when in its closed position. Similarly, any other flow control means (see end of this specification) provided to allow the user to modify the outflow from the appliance 10 must also be suitable for waste with a high percentage of liquid (i.e. waste that has a relatively low viscosity, meaning that the waste can flow in a manner similar to water or other liquids).

[0013] The valve 100 includes a body 110, an inlet connected to an outlet 102 by a flow path, and a closure device 120. The closure device 120 is movable between an open position and a closed position (and vice versa). In the closed position, the closure device 120 blocks the outlet 102 so that liquid cannot flow through the outlet 102. In the open position, the outlet 102 is open so that liquid is allowed to flow out of the outlet 102.

[0014] In some embodiments, one or more exterior surfaces of the valve 100 cooperate with one or more exterior surfaces of the outlet portion 20 to form a smooth transition between the outlet portion 20 and the valve 100 (see, e.g., FIGS. 2 and 11). In other words, the valve 100 is integrated into the outlet portion 20 to form a tail device. Such integration can be more comfortable for the user to wear. For example, sharp corners and parts of the brace 10 may be reduced from digging into the user's flesh, etc. In some embodiments, the outlet portion 20 provides the upper and lower exterior surfaces (of the tail device), and the valve 100 provides the left and right exterior surfaces. In some embodiments, the valve 100 is made from a soft and / or flexible material (e.g., to further enhance user comfort). Once the functionality of the valve has been described, how the valve is attached to the brace will be detailed below.

[0015] The features of the valve 100 will now be described in detail. All of the embodiments described herein may be combined with the ostomy appliance 10 structures described above.

[0016] As described above, the valve 100 includes a body 110, an inlet, an outlet 102, and a closure device 120. The body 110 is configured to be connected to the ostomy appliance 10 (and may be attached to the outlet portion 20 as described above). The inlet and outlet 102 are connected via a fluid path (i.e., a fluid path for waste from the valve 100 and the appliance to which the valve 100 is attached). As described above, the closure device 120 is movable between an open position and a closed position to open and close the valve 100.

[0017] In some examples (such as those shown in Figures 2-7), the closure device 120 is removably connectable to the body 110. In other words, the closure device 120 can be removed from the body 110 of the valve 100 and reattached as desired. Thus, the closure device 120 can be attached to and supported by the body 110 whether the valve 100 is open or closed.

[0018] In some embodiments, the closure device 120 includes a connecting member 122 that provides a removable connection with the body 110. In the illustrated example, the closure device 120 includes a closure body 124 and a connecting member 122.

[0019] In some embodiments, the connecting member 122 includes an elongated portion 126 that extends away from the closure 124 to provide a connection with the body 110. Thus, the connecting member 122 provides a protrusion that can be attached to the body 110 of the valve 100.

[0020] The closure body 124 supports a plug portion 130 that is configured to be positioned in the outlet 102 when the closure device 120 is in its closed position (i.e., blocking waste from exiting the valve 100). The plug portion 130 is thus retained in the outlet by a friction or press fit. The closure body 124 (and more particularly the plug portion 130) is configured to be insertable into the outlet 102 of the valve 100 regardless of whether the connecting member 122 is attached to the body 110 or not.

[0021] In some embodiments, the plug portion 130 includes a flange portion 130a that engages an inner surface inside the outlet 102. This aids in the connection between the closure and the valve body 110 and reduces the likelihood of the plug portion 130 dislodging on its own or accidentally exiting the outlet 102.

[0022] In some embodiments, the body 110 provides a first engagement formation 112 configured to receive a portion of the connecting member 122. The connecting member 122 also includes a corresponding engagement formation 128 configured to engage with the first engagement formation 112.

[0023] In this example, the first engagement formation 112 is a receiving portion. In other words, the body 110 includes a recess or opening that "receives" a portion of the connecting member 122 to retain and support the closure relative to the body 110. The corresponding engagement formation 128 includes a protrusion configured to engage with a recess or opening in the body 110. The recess or opening is positioned on a first side 110a of the body 110 and is spaced "back" of the outlet 102 (i.e., toward the collection volume of the appliance or upstream from the outlet 102).

[0024] In some embodiments, the first engagement formation 112 includes a channel 112a that leads to a recess or opening. The channel 112a provides an additional receiving portion for receiving the connecting member 122 (in this example, the elongated member 126 of the connecting member 122) when the corresponding engagement formation 128 is received in the first engagement formation 112. Thus, when the connecting member 122 is connected to the body 110, the outer surface of the body 110 matches the outer surface of the connecting member 122 to provide a smooth or continuous outer surface. This is advantageous because it reduces the likelihood that the connecting member 122 will get caught on an external object and become inadvertently detached from the body 110 (this is especially true when the user is using the appliance 10 but is unaware that this has occurred because they are not using the valve to empty the appliance 10).

[0025] In some embodiments, the connection between the closure device 120 and the body 110 allows rotation of the closure device 120 while still attached. In other words, the connecting member 122 can be rotated while engaging / connecting with the corresponding engagement formation on the body 110.

[0026] In the illustrated example (see especially FIG. 3), the corresponding engagement formation 128 of the connecting member 122 comprises a protrusion having a dome-shaped portion 128a and a narrow section 128b. The first engagement formation 112 comprises a recess with a surface opening narrowed relative to the width of the rear recess. In other words, the opening forms a pinch point. At least one of the materials of the dome-shaped portion 128a and the first engagement formation 112 is formed from an elastically deformable material. Thus, when the dome-shaped portion 128a is inserted into the recess through the opening, the opening or the dome-shaped portion deforms to allow the dome-shaped portion 128a to pass through the opening and then returns to its initial form / shape. When returning to its initial form, the material forming the opening resists the outward movement of the dome-shaped portion 128a (i.e., away from the body 110) but allows the narrow section to rotate while maintaining the dome-shaped portion 128a within the recess. Thus, the first engagement formation 112 resists removal of the corresponding formation 128 but allows the closure to rotate relative to the body 110 .

[0027] In some embodiments, the closure device 120 is connectable to the body 110 at two different locations. In other words, the connection member 122 can be attached to the body 110 at least two select locations or positions. These connection options are in addition to the positioning of the plug portion 130 relative to the outlet 102 required to close the valve 100 (e.g., the plug portion 130 / closure body 124 is always receivable by the outlet 102 to move the closure device 120 to its closed position).

[0028] In this example, the body 110 includes a second engagement formation such that the corresponding engagement formation 128 can engage with either the first engagement formation or the second engagement formation. In this example, the second engagement formation has a similar or identical configuration to the first engagement formation 112 such that the corresponding engagement formation 128 of the connecting member 122 can engage with either of these engagement formations as desired by the user.

[0029] In some embodiments, the first receiving formation 112 is disposed on the first side 110a of the body 110 and the second receiving formation is disposed on the second side 110b. In this example, the first side and the second side are on opposite sides of the body 110. Thus, the connecting member 122 can engage with either the first side 110a or the second side 110b of the body 110.

[0030] In embodiments where both the first and second engagement formations include a channel 112a extending toward a recess or opening, the other of the engagement formations 112 not used by the connecting member 122 also has a function. The corresponding engagement formation 128 and connecting member 122 are received in the channel and recess, respectively, to form a substantially continuous outer surface. On the opposite side 110a or 110b, the channel of the "other" of the first and second engagement formations provides a notch that a user can use to open the valve 100 (i.e., providing space for a user to grasp the closure 124 and pull it outwardly from the outlet 102 to move the closure device 120 to its open position).

[0031] In some embodiments, the closure 124 includes a gripping portion 132 that assists a user in moving the closure device 120 to its open and / or closed positions. In the illustrated example (see, e.g., FIG. 7 ), the gripping portion 132 includes a raised surface that provides an easier to grip surface than the smooth surface of the remainder of the closure 124.

[0032] In some embodiments, at least the connecting member 122 (and specifically the elongated portion 126) is formed from an elastic / elastically deformable material that allows the connection between the closure device and the body to be flexible and resist permanent deformation. In some embodiments, the valve 100 (i.e., the body 110 and the closure device 120) is formed from a single material (preferably a soft / soft or flexible material that provides a comfortable wearing experience to the user, such as TPE).

[0033] In use, the valve 100 is opened by moving the closure device 120 to its open position. Essentially, this should include unblocking the outlet 102. Thus, the closure body 124 is moved out of contact with the outlet 102. In addition, the closure device 120 can be removed from the body 110 of the valve 100 (this is shown in detail in FIG. 3). In some embodiments, the ability to rotate the closure device 120 is also provided as described above. The ability to leave the closure device 120 attached to the body 110 of the valve 100 while the outlet 102 is open is shown in more detail in FIGS. 4 and 5. FIG. 5 shows the closure body 124 when it is initially removed from the outlet 102. As the connection member 122 flexes while maintaining connection with the body 110, the closure body 124 can be moved away from the outlet 102. FIG. 4 shows the closure device 120 rotated upwards away from the outlet 102.

[0034] When the user wears the accessory 150 on their appliance 10 (see, for example, FIG. 6), the closure device 120 remains connected to the body 110 of the valve 100 even if it is moved away. Alternatively, the closure device 120 may be completely removed and stored elsewhere while the accessory 150 is in use. FIG. 6 shows the attachment of a so-called "night drainage adapter" that allows the user to connect a separate tube 152 to the appliance 10 to drain waste into a second collection container. This can extend the time during which the appliance 10 is idle (which is especially useful at night when a person wants to sleep for a long time). The ability to remove the closure device 120 can improve comfort by allowing additional materials of the valve 100 to be placed elsewhere (not in close proximity to the body).

[0035] A second embodiment of the valve is shown in Figures 8 to 11. Unless expressly stated, optional features relating to the valves shown in Figures 2 to 7 are equally usable for the valves of Figures 8 to 11. Where features of the valve or appliance are the same or similar to those already described above, these are given the same reference numbers with a prime added (i.e. 10 becomes 10').

[0036] The valve 100' includes an outlet 102', and a closure device 120'. Again, the closure device 120' is movable between a closed position and an open position. In the closed position, the closure device 120' blocks the outlet 102' such that liquid cannot flow therethrough. In the open position, the outlet 102' is open and liquid is permitted to flow out of the outlet 102'.

[0037] In some embodiments, the closure device 120' is connectable / connected to the body 110' at two locations (see especially Figures 8 and 10). In other words, the closure device 120' is permanently or removably connected to two locations on the body 110'. In the illustrated example, the connecting member 122' is permanently attached to the body 110'.

[0038] In some embodiments, the closure device 120' includes a first connecting member and a second connecting member 122'. The first connecting member and the second connecting member 122' each connect to the body 110'. In the illustrated example, the closure device 120' includes a closure body 124' and a first connecting member and a second connecting member 122'.

[0039] In some embodiments, each connecting member 122' includes an elongated portion 126' that extends away from the closure body 124'. In some embodiments (e.g., FIG. 8 et seq.), the closure body 124' is generally central and between the two connecting members 122'. In other words, a first connecting member 122' connects to a first side of the closure body 124' and a second connecting member 122' connects to a second side of the closure body 124'. The connecting members 122' are on opposite sides of the closure body 124'.

[0040] In some embodiments, a first connecting member 122' connects to a first side 110a' of the body 110' and a second connecting member 122' connects to a second side 110b' of the body 110'. Thus, these connecting members 122' are on opposite sides of the body 110' of the valve 100'. In this example, these connecting members 122' form the outer "sides" of the valve 100', in that the first connecting member 122' extends from a first side of the closure 124' to the first side 110a' of the body 110' and the second connecting member 122' extends from the second side of the closure 124' to the second side 110b' of the body 110'.

[0041] Further, in this example, the closure 124' again supports a plug portion 130' configured to be positioned in the outlet 102' when the closure device 120' is in its closed position (i.e., blocking waste from exiting the valve 100'). Thus, the plug portion 130' is retained in the outlet 102' by a friction or press fit. In this embodiment, the first and second connecting members 122' provide an additional biasing force urging the closure 124' toward the closed position when it is aligned or substantially aligned with the outlet 102'.

[0042] Similar to the single connection member valve version discussed above, the plug portion 130' includes a flange portion 130a' that engages the inner surface inside the outlet 102'. This further strengthens the connection between the closure and the valve body 110' and reduces the likelihood of the plug portion 130' dislodging itself / accidentally exiting the outlet 102'.

[0043] In some embodiments, the closure 124' includes a gripping or user aid 132' configured to assist a user in gripping and / or moving the closure 124'. The aid 132' may include finger recesses / detents and / or raised ridges to give the user additional grip.

[0044] The manner in which the valve 100' functions will be described below, as it differs from the valve 100 described above due to the two connection points between the closure device 120' and the body 110'.

[0045] As already mentioned, when the valve 100' shown in Figures 8 and 9 is closed (i.e., when the closure device 120' is in its closed position), the closure body 124' is generally aligned with the outlet 102' (which allows the plug portion 130' to be inserted into the outlet 102' to close the valve 100'). In some embodiments, the first and second connecting members 122' are formed from a resiliently deformable or biased material. This means that to remove the plug portion 130' of the closure body 124' from the closed position (i.e., to move them outward and away from the body 110'), the connecting members 122' are stretched from their original shape. Thus, the connecting members 122' act to resist removal of the closure body 124' from the closed position. In some embodiments, the connecting members 122' apply an additional force to the closure body 124' when in the closed position. Thus, the connecting member 122' "pulls" the closure 124' into intimate contact with the body 110' (i.e., the connecting member 122' is deflected from its original shape / size / configuration so as to apply a biasing force toward the body 110').

[0046] The closure device 120' is held or positioned adjacent to the body 110' when in its open position. In some embodiments (see, e.g., FIGS. 10 and 11), the closure device 120' is held in contact with the body 110' when in its open position.

[0047] To move the closure 124' out of alignment (i.e., closed) with the outlet 102', the closure 124' can be pulled away from the body 110' and / or a lateral force can be used to rotate the closure 124' toward the front or rear of the body 110'. This movement resists pulling on the connecting members 122' on each side of the closure 124'. The result of this movement means that the closure 124' is urged away from the outlet 102'.

[0048] In some embodiments, the closure 124' is moved to an offset position out of alignment with the outlet 102'. The first and second connecting members 122' are deflected to hold the closure 124' against / in contact with the exterior surface of the body 110'. As noted above, because the connecting members 122' are made from a resiliently deformable material, being deflected from their natural shape applies a biasing force to the closure 124' toward the side of the body 110'.

[0049] When a user wishes to close the valve 100', the closure body 124' must be actively moved from its open position towards the outlet 102' (i.e. a force must be applied to the closure device 120' when in the open position to move it back to the closed position). This is advantageous as the closure device 120' is stably held in a well-defined / predetermined position away from the outlet (and relative to the body 110' of the valve) in the open position. Whereas previous designs often relied on a closure body that was allowed to float in free space when in the open position, the closure body is held in a position that does not interfere with further use of the valve 100'.

[0050] When the user attaches the accessory 150' to the appliance 10' (see, for example, FIG. 11), the closure device 120' is held against the side of the body 110' even when moved away. FIG. 11 illustrates the attachment of a night-drainage adapter, which allows the user to connect a separate tube 152' to the appliance 10' and drain waste into a second collection container to extend the time between appliance 10 empties.

[0051] Having a predetermined location that the closure 124' is held in when in the open position increases comfort for the user as the closure does not hang free from the brace 10' in a potentially uncomfortable position.

[0052] Additional features of the valves 100, 100' that affect how the valves 100, 100' are attached to the ostomy appliances 10, 10' are described below. Figures 7 and 9 show valves already having the features described above. These valves are shown alone and not attached to any appliance 10, 10'. Where the features of the valves are described, for clarity, only reference numbers without primes are used. However, it should be understood that references to valves with prime symbols are equally applicable.

[0053] The body 110 includes a first mounting portion 200 and a second mounting portion 202. Each mounting portion 200, 202 extends away from the inlet. In other words, the valve 100 includes a pair of mounting portions 200, 202 that are elongated and project away from the body 110 of the valve 100. In a top-down or bottom-up view of the valve 100, the mounting portions 200, 202 extend away from the body 110 such that the overall valve shape is generally U- or V-shaped (i.e., each mounting portion 200, 202 forms a limb).

[0054] The first and second mounting portions 200, 202 provide one or more mounting surfaces for connection to the ostomy appliance 10. In the illustrated example, the mounting portions 200, 202 provide a first mounting surface 210 and a second mounting surface 212. The first mounting surface 210 lies substantially in a first plane and the second mounting surface 212 lies substantially in a second plane. The first and second planes are inclined relative to one another.

[0055] In some embodiments, the first mounting surface 210 is formed from one exterior surface of the body 110. The second mounting surface 212 is formed from the other exterior surface of the body 110. In the illustrated example, the exterior surfaces forming the first and second mounting surfaces are on opposite sides of the valve 100. In other words, the first mounting surface 210 forms an upper surface of the valve 100 and the second mounting surface 212 forms a lower surface of the valve 100.

[0056] In this example, the inlet and outlet 102 and the flow passages extending therebetween extend through a generally central portion of the body 110. The generally central portion of the body thus extends between the first mounting surface 210 and the second mounting surface 212. In other words, the exterior surface of the generally central portion of the body and the exterior surfaces of the first mounting portion 200 and the second mounting portion 202 (upper and lower) form the first mounting surface 210 and the second mounting surface 212.

[0057] In some embodiments, the first mounting portion 200 and / or the second mounting portion 202 are tapered (i.e., gradually narrower) as they extend away from the central portion of the body of the valve 100. In other words, the first mounting portion 200 and the second mounting portion 202 each generally form a wedge shape when viewed from the side. Thus, the first and second planes in which the first mounting surface 210 and the second mounting surface 212 generally extend intersect to form the point where the valve ends. In other words, the first mounting surface 210 and the second mounting surface 212 meet at one end of the first mounting portion 200 to form a first tip 220 (i.e., one of the two ends of the U / V shape). Similarly, at the second mounting portion 202, the first mounting surface 210 and the second mounting surface meet to form a second tip 222 (at the other end of the U / V shape).

[0058] In some embodiments, one or both of the first tip 220 and the second tip 222 include a notched portion 220a, 222a. This is advantageous as it aids in the manufacturing process and makes it easier to achieve a seal between the material of the outlet portion 20, 20' and the mounting surface 210, 212.

[0059] The valve 100 is mounted to the outlet portion 20. In this example, a first mounting surface 210 is connected to the first outlet wall 22 and a second mounting surface 212 is connected to the second outlet wall 24. Preferably, the outlet portion 20 is heat welded to the first mounting portion 210 and the second mounting portion 212, which provides a safe and reliable seal between these components.

[0060] Thus, the tail device includes the outlet section 20 and the valve 100. Internally, the passageway for waste (before it enters the flow path of the valve 100) is formed by the first and second outlet walls 22 and 24 of the valve 100 and the first and second mounting sections 200 and 202. At the top of the outlet section 20, the first and second outlet walls 22 and 24 are attached together. Then, as the valve begins (further away from the collection volume), the first and second tips 220 and 222 become included in the "wall" (i.e., the first and second outlet walls are no longer attached to each other, but instead are attached to the first and second mounting surfaces 210 and 212). As more of the valve 100 is assembled (i.e., closer to the inlet and outlet 102), the mounting sections 200, 202 of the body 110 become progressively wider. Thus, the sides of the tail device become progressively wider as it approaches the inlet / outlet 102. This configuration provides a smooth taper of the surface of the appliance 10 as previously described.

[0061] In some examples, the valve 100 includes a flow control feature 300 (see FIGS. 12 and 13). The flow control feature 300 is configured to be initially set to an open state and has a closed state in which the flow of liquid from the outlet 104 is prevented or at least inhibited. In other words, the flow control feature 300 remains open (and allows waste material to pass to the outlet) unless moved to the closed state. In some examples, the flow control feature 300 is moved to its closed state by user manipulation.

[0062] It should be understood that the flow control formation 300 may be provided on any of the valves 100, 100' described above. At least a portion of the flow control formation 300 is disposed internal to the appliance 10 (i.e., within the tail arrangement formed by the outlet portion 20 and the valve 100). The internal nature of the flow control formation 300 allows for effective flow control by the user.

[0063] These figures show two different configurations of the flow control formation 300. The example shown in Figures 12A and 12B will be described first. The flow control formation 300 has a deflectable portion 302 and a further second deflectable portion 304. The first and second deflectable portions 302, 304 are movable towards each other to close the flow path towards the outlet 104. It should be understood that there may be a single deflectable portion that moves against other surfaces of the valve 100 or against other portions of the appliance 10 to close the flow path.

[0064] The first and second deflectable portions 302, 304 are disposed within the orthosis 10. In this example, the first and second deflectable portions 302, 304 are resiliently biased to an initial shape and / or position (shown in FIG. 12A ), which corresponds to an open state of the flow control formation 300.

[0065] In this illustrated example, the first and / or second deflectable portions 302, 304 protrude from the body 110 of the valve 100. In other words, the deflectable portions 302, 304 extend "upstream" of the body 110 and to the outlet 104.

[0066] The first and second deflectable portions 302, 304 are disposed about an opening 310 in the body 110 that leads to the outlet 104. The first deflectable portion 302 extends around half of the opening and extends away / upstream from the body 110 (i.e. forming an upper beak). The second deflectable portion 304 extends around a second half of the opening and also extends away / upstream from the body 110 (i.e. forming a lower beak).

[0067] In its "normal" or default position, the ends 302a, 304a of the first and second deflectable portions 302, 304 that are furthest from the opening in the body 110 are spaced apart from each other to provide an open pathway for liquid / waste to flow therethrough (whether or not waste flows out of the valve 100 depends on the position of the closure device 120 (not shown in Figures 12A and 12B)).

[0068] In use (i.e., when a user wishes to affect the flow of waste through the valve without using the closure device 120), the deflectable portions 302, 304 are moved towards each other (i.e., opposing pressure is applied to each "side"). The ends 302a, 304a are moved into contact with each other. The upper and lower beaks contact each other along the sides in addition to the ends, closing the flow path (i.e., at least to some extent, pressure on either side of the beaks temporarily seals the sides / edges, preventing or at least inhibiting liquid from flowing into the opening 310).

[0069] The flow control formation 300i will remain in this closed state for as long as there is pressure holding the deflectable portions 302, 304 together, so that once the user is happy to allow liquid to flow again, the pressure is released and the flow path reopens.

[0070] The example shown in Figures 13A and 13B is described below. The flow control formation 300 includes a contact surface 320 upstream of the outlet 104 (i.e., the contact surface 320 is disposed between the interior collection volume of the orthosis 10 and the outlet 104 of the valve 100). Moreover, in this example, the contact surface 320 is internal to the orthosis 10 (i.e., between the layers of the outlet portion 20). In this example, the contact surface 320 extends from one mounting portion 200 to the second mounting portion 202 of the body 110. Thus, the contact surface 320 extends across the space formed between the limbs of the body 110.

[0071] In this example, contact surface 320 includes a convex portion (which is preferably generally central to contact surface 320 and generally aligned with the opening in body 110 that connects to outlet 104). In the example shown, contact surface 320 is convex on one side, but it should be understood that both sides may include a convex portion.

[0072] The valve 100 is positioned / mounted between the first outlet wall 22 and the second outlet wall 24 (if the appliance 10 is nevertheless made to have an outlet portion 20 integral to the first wall 12 and the second wall 14, the valve 100 would instead be positioned / mounted between the first wall 12 and the second wall 14). What is important about the interface 320 is that the flexible membrane of the appliance 10 (i.e., the layer provided by the walls 12, 14, 22, 24) extends on either side of the interface 320 to provide a flow path between the interior collection volume and the outlet 104.

[0073] In the absence of interaction from a user or other pressure on the contact surface 320, the flow path between the collection volume and the outlet 104 of the valve 100 remains open (i.e., whether or not liquid is allowed to flow out of the valve is determined by the closure device 120 / whether the outlet 104 is open or closed).

[0074] In use (i.e., when a user wishes to affect the flow of waste through the valve 100 without using the closure device 120), a compressive force is applied to one or both sides of the contact surface 320 to close the flow path. In other words, the film of the wall of the appliance 10 is pinched against the contact surface 320 to block the flow path to the outlet 104. The compressive force / pressure may be applied by a user, for example, using fingers and thumb to pinch a layer of film against the contact surface 320 to block the flow of liquid. Thus, the convexity of the contact surface 320 may be advantageous, as it allows the curved surfaces of the fingers of the hand (i.e., the thumb / fingers of the user of the appliance 10 or the assisting nurse) to pinch the layer efficiently and / or comfortably.

[0075] The flow path remains closed and liquid flow is prevented (or at least inhibited) for as long as the layer is pressed against the contact surface 320. Once the closed state is no longer required, the pressure is released and the layer (first and second walls 12, 14 / first and second outlet walls 22, 24) is pushed away from the contact surface 320 by the liquid flowing (e.g. under gravity) towards the outlet 104.

[0076] In an embodiment, the flow control shaper 300 advantageously allows manual alteration of the flow of liquid from the valve 100 independent of the closure device 120. Thus, a user wishing to empty the appliance 10 can use the flow control shaper 300 to keep the valve 100, 100' in a "closed" position even after the closure device 120 has been moved to its open position. This means that the user can instantly stop the flow of liquid from the outlet 104 even after opening the closure device 120, thus avoiding unwanted waste material from flowing onto fingers, clothing or other surfaces, even before the valve 100 is oriented to direct the flow into a toilet or other receptacle. This provides a clean and dignified experience for the person using the appliance 10.
