Description

[0001] Ostomy Appliance

[0002] Technical Field of the Invention

[0003] The present invention relates to an ostomy appliance, in particular to an ostomy baseplate for attaching a fluid collection pouch to an ostomate.

[0004] Background to the Invention

[0005] The present disclosure relates to devices that attach to a patient's body after they have undergone a surgical ostomy procedure, typically to address a problem with their gastrointestinal tract. The varied problems they experience interfere with their body's normal processes for processing and collecting the waste products from the digestive processes. Ostomates, as these patients are referred to, are typically required to wear and maintain these waste-collection devices for significant portions of their life, if not for the remainder of their life. Typically, teh devices are comprised of an adhesive “doughnut” surrounding the stoma's exit from their abdomen. The adhesive adheres to the patient on one side and to a baseplate on the other. The baseplate typically comprises a coupling ring comprising means for releasable attachment of an effluent collection bag or pouch. The system is intended during operation to provide a liquid and reasonably gas-tight seal so the ostomate can enjoy an active and socially engaged life.

[0006] The forces required to decouple and recouple the fluid collection pouch to the coupling ring are typically reacted directly back against the patient's abdomen. Many ostomates experience discomfort as a result of an attachment force applied through the ostomy appliance to the skin, when two coupling parts are pressed together. The problem of discomfort is especially important during post-operative care, when the stoma surgery is recent, and the abdominal skin is very tender.

[0007] To reduce the pressure applied to the abdominal skin around an ostomate’ s stoma when coupling and decoupling a fluid collection pouch, it is known to provide a multiple component system (typically comprising three or more components) which are known to include a thermoformed holding part. Such systems are known in the art as ‘low-pressure systems’ as they aim to reduce the pressure exerted upon an ostomate’ s skin during coupling and decoupling a fluid collection pouch. The thermoformed holding part provides for a surface which teh ostomate may hold when coupling and decoupling the fluid collection pouch, therefore, somewhat reducing the pressure directly exerted upon the ostomate’ s abdominal skin and, to some extent, facilitating the action of coupling and decoupling the fluid collection pouch.

[0008] Whilst efforts have been made to provide low pressure systems, such systems are disadvantageous, not elast from a manufacturing point of view. For example, in a multiple component system, each component is required to be manufactured separately and then bonded together as is desired to form a final product. Separately manufacturing the multiple components is inherently costly and requires additional processing steps to then bond together each component. Thus, the known low-pressure systems are disadvantageous in terms of their cost and speed of manufacture.

[0009] Moreover, there is a higher risk of production downtime when relying on the separate manufacture of multiple components. In the event that the equipment used to manufacture one component, or the equipment used to bond together the multiple components in the final product, is not working or requires servicing, the production of the low-pressure system must be halted until the necessary equipment is working again.

[0010] Further, conventional ostomy appliances which comprise multiple components required to be bonded together to form the ostomy appliance, for example an ostomy appliance comprising a separately formed baseplate, coupling component and finger grip, may suffer from leaking of effluent between the adjacent surfaces which were initially bonded together. Moreover, in conventional ostomy appliances comprising multiple components, effluent may pool in crevices that are inherent in the design of such ostomy appliances. For example, effluent may pool in crevices between adjacent surfaces of a baseplate and a coupling component, typically where a bond between such components exits. Pooled effluent retained within crevices of the ostomy appliance may become more odorous than effluent held within a fluid collection pouch. This may be significantly unpleasant for the ostomate who may be inclined to change their ostomy appliance more often than should be required.

[0011] It is an object of embodiments of the present invention to at least partially overcome or alleviate the above problems, and / or to provide an improved ostomy appliance. Summary of the Invention

[0012] The present invention concerns an ostomy appliance. The ostomy appliance may comprise a baseplate. The ostomy appliance may comprise an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma. The baseplate may comprise an aperture therein to permit the passage of effluent therethrough. The ostomy appliance may comprise a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch. The baseplate may comprise a finger grip. The finger grip may extend radially outwardly from the baseplate. The finger grip may be formed integral with the baseplate.

[0013] In a preferred aspect of the invention, there may be provided an ostomy appliance comprising: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma, the baseplate comprising an aperture therein to permit the passage of effluent therethrough; wherein the baseplate further comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate.

[0014] Advantageously, the provision of a finger grip being formed integral with a baseplate means that the ostomy appliance of the invention is formed of fewer components compared to conventional low-pressure ostomy systems because the baseplate and finger grip are integrally formed. Thus, the ostomy appliance of the invention is formed at lower cost and with fewer steps in its manufacture. Moreover, compared to the prior art, the degree of processing required to combine the components of the ostomy appliance of the invention is reduced, not least because the ostomy appliance is formed of fewer components. As such, the ostomy appliance of the invention can be formed more quickly, at lower cost and with fewer processing steps following manufacture of each component, compared with ostomy appliances of the prior art.

[0015] Further, as the ostomy appliance of the invention is formed of fewer components compared to conventional low-pressure ostomy systems, the ostomy appliance requires fewer bonds to be formed between adjacent surfaces when manufacturing the ostomy appliance of the invention. As such, fewer crevices exist between adjacent components which are bonded together. Thus, the risk of effluent pooling in such crevices is significantly reduced, if not eliminated. As such, the aforementioned drawbacks associated with pooling of effluent are ameliorated. .

[0016] The provision of a baseplate comprising a finger grip which extends radially outwardly from the baseplate means that the ostomy appliance of the invention benefits from the aforementioned advantages of low-pressure systems, such as, when coupling and decoupling a fluid collection pouch, reducing the pressure directly exerted upon the ostomate’s abdominal skin and facilitating the action of coupling and decoupling the fluid collection pouch, especially for users with limited dexterity. However, advantageously, the ostomy appliance of the invention benefits from such advantages while, due to the provision of the finger grip being formed integral with the baseplate, not suffering from the aforementioned drawbacks described in relation to the prior art.

[0017] According to a first aspect of the invention, there may be provided an ostomy appliance comprising: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma, the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate further comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate.

[0044] Advantageously, providing a finger grip angled with respect to the plane of the aperture in the baseplate, in particular in embodiments comprising a finger grip at an angle as exemplified above, means that the finger grip is easily gripped by an ostomate, in particular an ostomate with limited dexterity, such that coupling and decoupling of the fluid collection pouch to the baseplate is facilitated and the pressure exerted upon the abdominal skin of the ostomate when doing so is reduced.

[0045] The finger grip and the baseplate may be formed of the same material. The finger grip and the baseplate may be formed of a thermoplastic material, for example ethylene-vinyl acetate (EVA), or polyethylene (PE).

[0046] The finger grip and the baseplate may define an annular space for the ostomate to insert one or more fingers or one or both hands when coupling and decoupling the fluid collection bag from the baseplate.

[0047] The finger grip may be convex with respect to the plane of the aperture in the baseplate.

[0048] In some embodiments, the ostomy appliance may comprise: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate, further wherein the finger grip is convex with respect to the plane of the aperture in the baseplate.

[0050] In some embodiments, the ostomy appliance may comprise: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate, further wherein the finger grip is concave with respect to the plane of the aperture in the baseplate.

[0051] In some embodiments, the ostomy appliance may comprise: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate, further wherein the finger grip is concave or convex with respect to the plane of the aperture in the baseplate.

[0052] Beneficially, in embodiments comprising a finger grip which is convex or concave with respect to the plane of the aperture in the baseplate, there may be provided a relatively wider annular space within which an ostomate may more easily insert one or more fingers or one or both hands to better access the finger grip when coupling and decoupling the fluid collection pouch from the baseplate.

The baseplate may comprise an inner surface which is angled with respect to the plane of the aperture in the baseplate. The coupling component may be bonded directly to the angled inner surface of the baseplate. Advantageously, in embodiments comprising a coupling component bonded directly to the angled inner surface of the baseplate, the height profile of the ostomy appliance may be reduced such that the ostomy appliance maintains a discreet profile when worn. Moreover, such embodiments are particularly suitable for ostomates having a relatively small physique as the prominence of the ostomy appliance is reduced.

[0057] In some embodiments, the ostomy appliance may comprise: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate, further wherein the baseplate comprises an inner surface which is angled with respect to the plane of the aperture in the baseplate, and wherein the coupling component is bonded to the angled inner surface of the baseplate. The coupling component may be bonded to the baseplate by heat- welding, laserbonding, ultrasonic welding or adhesive bonding.

[0058] The coupling component may be formed integral with the baseplate.

[0059] The coupling component may be formed integral with the finger grip. In embodiments comprising a coupling component formed integral with the finger grip, the number of bonds in the ostomy appliance is further reduced. Beneficially, this means that the risk of effluent leaking from within the confines of the ostomy appliance onto undesired locations on the surface of the ostomy appliance and into crevices found on the components of the ostomy appliance, is significantly reduced. Thus, the ostomy appliance of the invention provides for a more reliable and hygienic low-pressure system compared to that of the prior art.

[0060] The baseplate may comprise a side wall. The side wall may be arranged perpendicular, or at least substantially perpendicular, to the plane of the aperture in the baseplate. The side wall may be arranged parallel to, or at least substantially parallel to, the direction of flow of effluent when the ostomy appliance is in use. The side wall may be arranged parallel to, or at least substantially parallel to, an axis through which effluent flows in use.

[0061] The finger grip may extend radially outwardly from the side wall of the base plate. The finger grip may extend radially outwardly from the side wall in the same plane as the plane of the aperture in the baseplate. The finger grip may extend radially outwardly from the side wall and the finger grip may be concave with respect to the plane of the aperture in the baseplate. The finger grip may extend radially outwardly from the side wall and the finger grip may be convex with respect to the plane of the aperture in the baseplate. The side wall may extend circumferentially around the baseplate.

[0062] The side wall may extend from an inner surface of the baseplate. The side wall may extend from lower region of the baseplate. For example, in embodiments comprising a baseplate having an angled inner surface, the side wall may extend from a lower region, in particular from the base, of the angled inner surface of the baseplate. In embodiments comprising a side wall, the side wall may define an annular space between the baseplate and the finger grip.

[0063] The coupling component may be bonded to the side wall of the baseplate. The coupling component may be formed integral with the side wall of the baseplate.

[0073] The adhesive component may take the form of a hydrocolloid adhesive disc. The hydrocolloid adhesive disc may comprise an upper surface partially adhered to the outer surfaces of the baseplate, and an opposing lower surface. The upper and lower surfaces of the hydrocolloid adhesive disc may be adhesive. This may be because the hydrocolloid adhesive disc may be formed of a hydrocolloid adhesive.

[0074] The hydrocolloid adhesive disc may be mouldable. The mouldable hydrocolloid adhesive disc may be moulded around a stoma. In other embodiments, the hydrocolloid adhesive disc may be cut-to-fit, as necessary to fit around a stoma.

[0075] The hydrocolloid adhesive disc may comprise an adhesive disc aperture. The hydrocolloid adhesive disc aperture may be arranged centrally on the hydrocolloid adhesive disc.

[0076] The hydrocolloid adhesive disc may extend beyond the radially outer edge of the baseplate.

The flexible collar may be formed of a sheet of woven material. The sheet of woven material may have a ring shape. The flexible collar may comprise an inner edge. The inner edge may have a circular shape. The inner edge may be sized such that the collar overlaps an outer periphery of the hydrocolloid adhesive disc forming an overlap region. The flexible collar may be adhered to the hydrocolloid adhesive disc in the overlap region. The outer edge of the flexible collar may have an ovular circumference. The ovular circumference may be sized to correspond to the shape of a fluid collection pouch, or part thereof.

[0079] In embodiments comprising a flexible collar formed of a sheet of woven material, the woven material may comprise cotton, polyester, polypropylene, a blend of cotton and polyester yams, or a mixture thereof.

The channel may have a complementary lug for interlocking with the undercut lug of the upstanding rib when the rib is received in the channel so as to provide a snap-fit coupling.

[0083] The baseplate and the coupling component may be immovably coupled to one another.

[0084] The coupling component may extend from the finger grip. The finger grip may comprise a lower surface. The lower surface may face away from an ostomate in use. The coupling component may extend from the lower surface of the finger grip.

[0085] The baseplate may comprise a radially outer edge. The radially outer edge may be formed as the periphery of an outer radial part of the baseplate. The finger grip may extend radially outwardly beyond the radially outer edge of the baseplate.

[0086] In some embodiments, the ostomy appliance may comprise: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; wherein the baseplate comprises a finger grip which extends radially outwardly from the baseplate, further wherein the finger grip is formed integral with the baseplate, further wherein the baseplate comprises a radially outer edge and the finger grip extends radially outwardly beyond the radially outer edge of the baseplate.

[0087] The invention according to the first aspect may include any features, including optional features, of the invention according to any other aspect. Accordingly, in a second aspect of the invention there is provided an ostomy appliance comprising: a baseplate and an adhesive component for adhering the baseplate to the abdomen of an ostomate around a stoma; the baseplate comprising an aperture therein to permit the passage of effluent therethrough; and a coupling component for coupling the baseplate to a corresponding coupling component of a fluid collection pouch; and a finger grip which extends radially outwardly from the ostomy appliance; wherein the baseplate and coupling component are immovably coupled to one another.

[0088] Conventionally, movement of a coupling component relative to a baseplate may be problematic for an ostomate as it means they are required to hold the coupling component steady while also manoeuvring a fluid collection pouch into position to enable coupling of the pouch to the coupling component. For users with limited dexterity, this is particularly problematic and may cause unnecessary stress and burden.

[0089] Advantageously, the provision of a baseplate and coupling component immovably coupled to one another facilitates coupling and decoupling of a fluid collection pouch to the baseplate, especially for users with limited dexterity. This is because movement, even slight movement, of the coupling component relative to the baseplate is prevented. As such, when coupling the fluid collection pouch to the baseplate, the lack of movement between the coupling component and the baseplate allows the ostomate to more easily arrange the fluid collection pouch relative to the coupling component for coupling the fluid collection pouch to the coupling component. The ostomate may also find benefit in being able to use movement of their body, to which the baseplate is attached, instead of one or both of their hands, to help bring the coupling component into aligned proximity with the fluid collection pouch when coupling the pouch to the coupling component.

[0090] The provision of a finger grip further facilitates coupling and decoupling of a fluid collection pouch to the baseplate. The provision of a baseplate comprising a finger grip which extends radially outwardly from the baseplate means that the ostomy appliance benefits from the aforementioned advantages of low-pressure systems, such as, when coupling and decoupling a fluid collection pouch, reducing the pressure directly exerted upon the ostomate’ s abdominal skin and facilitating the action of coupling and decoupling the fluid collection pouch, especially for users with limited dexterity.

[0145] Figure 12 shows a cross sectional view of a twelfth embodiment of an ostomy appliance according to the present invention; and

[0146] Figure 13 shows a cross sectional view of a thirteenth embodiment of an ostomy appliance according to the present invention. With reference to Figure 1, an ostomy appliance 1 according to an embodiment of the present invention is shown. The ostomy appliance 1 comprises a baseplate 2 in the form of a rigid convex disc.

[0147] The baseplate 2 of the embodiment is generally annular in shape and is formed of a finger grip 6 and an outer radial part 10, each extending from an angled part 7’ ’ of the baseplate 2. The baseplate 2 comprises a radially inner edge 16 which defines the outline of an aperture 4 in the centre of the baseplate 2. The angled part 7” of the baseplate 2 is angled with respect to the plane of the aperture 4. The plane of the aperture 4 is perpendicular, or at least substantially perpendicular, to the direction of flow of effluent through the aperture 4 when in use. The angled part 7” of the baseplate

[0148] 2 comprises an inner surface 7, which in this embodiment is angled with respect to the plane of the aperture 4, and an outer surface 7’. In use, the inner surface 7 faces away from the ostomate, and the outer surface 7’ faces toward the ostomate. Distal to the radial inner edge 16 of the baseplate 2 is a radially outer edge 17 formed as the periphery of an outer radial part 10 of the baseplate 2. The outer radial part 10 comprises an outer surface 10’ and an inner surface 10”. In use, the outer surface 10’ faces away from the ostomate, and the inner surface 10” faces toward the ostomate.

[0149] Laminated to an outer surface 7’, 10” of the baseplate 2 is an adhesive component for coupling the baseplate 2 to the abdomen of the ostomate around a stoma (not shown). The adhesive component takes the form of a hydrocolloid adhesive disc

[0150] 3 having an upper surface 3’ partially adhered to the outer surface 7’, 10” of the baseplate 2, and an opposing lower surface 3”. The upper 3’ and lower 3” surfaces are adhesive, as the hydrocolloid adhesive disc 3 is formed of a hydrocolloid adhesive. In this particular embodiment, the hydrocolloid adhesive disc 3 is mouldable, so it can be moulded around a stoma. In alternative embodiments, the hydrocolloid adhesive disc 3 could be cut-to-fit, as necessary to fit around a stoma.

[0151] The hydrocolloid adhesive disc 3 extends slightly beyond the radially outer edge 17 of the baseplate 2, it also extends radially inward over the aperture 4 such that apart from at an adhesive disc aperture 18 arranged centrally on the hydrocolloid adhesive disc 3, the hydrocolloid adhesive disc 3 occludes the aperture 4 in the baseplate 2. The adhesive disc aperture 18 is sized such that is has a smaller diameter than the typical stoma (not shown).

[0152] Arranged on the surface 3” of the hydrocolloid adhesive disc 3 opposing that which is laminated to the baseplate 2 is a baseplate release liner 12 which extends across the entire surface of the hydrocolloid adhesive disc 3.

[0153] Arranged radially outward of the baseplate 2 and extending circumferentially around it is a flexible collar 13. The collar 13 is formed of a sheet of non-woven material having a ring shape. The inner edge has a circular shape and is sized such that the collar 13 overlaps the outer periphery of the hydrocolloid disc 3. The flexible collar is adhered to the hydrocolloid disc 3 in the overlap region. The outer edge of the collar 13 has an ovular circumference, in some embodiments this may be sized to correspond to the shape of a fluid collection pouch (not shown), or part thereof.

[0154] A lower surface of the collar is provided with an adhesive coating 14, in this embodiment this adhesive coating 14 comprises an acrylic adhesive with a thickness of approximately 0.5 mm. In other embodiments, alternative adhesives may be used, for example hydrocolloid adhesives. The lower surface of the collar 13 is further provided with a collar release liner 15 which is releasably adhered to the adhesive coating 14.

[0155] In the described embodiment, the finger grip 6 is formed integral with the baseplate 2 such that the angled part 7” of the baseplate 2, the outer radial part 10 of the baseplate 2 and the finger grip 6 are formed integral, as a single component.

[0156] The ostomy appliance 1 further comprises a coupling component 5. In the described embodiment, the coupling component 5 is also formed integral with the baseplate 2, such that the angled part 7” of the baseplate 2, the outer radial part 10 of the baseplate 2, the finger grip 6 and the coupling component 5 are formed integral, as a single component.

[0157] The coupling component 5 is configured to releasably attach to a complementary coupling part (not shown) secured to a fluid collection pouch (not shown) around an entrance aperture (not shown).

[0158] In the described embodiment, the coupling component 5 and its complementary coupling part may form a mechanical engagement (for example, a mechanical interlock or an interference fit). The coupling component 5 may comprise an upstanding rib 5’. The upstanding rib 5’ may comprise an undercut lug 5” and a resilient seal 5”’. The complementary coupling part may comprise a channel for receiving the upstanding rib 5’. The channel may have a complementary lug for interlocking with the undercut lug 5” of the upstanding rib 5’ when the rib 5’ is received in the channel so as to provide a snap-fit coupling.

[0159] In the embodiment shown in Figure 1, the baseplate 2 comprises a side wall 8, formed integral with the baseplate 2, and which extends from the base of the angled part 7” of the baseplate 2. From a lower end of the side wall 8 extends radially outwardly from the baseplate 2 the finger grip 6. The finger grip 6 extends radially outwardly from the baseplate 2 in the plane of the aperture 4 in the baseplate 2. The finger grip 6 and the outer radial part 10 of the baseplate 2 are substantially parallel to one another. The coupling component 5 is arranged protruding from a lower surface of the finger grip 6, away from the ostomate when in use.

[0160] The finger grip 6 and the outer radial part 10 of the baseplate 2 define an annular space 11 for the ostomate, in use, to insert one or more fingers or one or both hands when coupling and decoupling the fluid collection bag from the baseplate 2.

[0161] In use, the user takes an ostomy appliance 1 and removes the baseplate release liner 12 and, in this embodiment, manipulates the mouldable adhesive disc 3 to increase the diameter of the aperture 18 therein such that it is greater than the diameter of the stoma (in embodiments where the adhesive disc is not mouldable, it may instead be cut to fit). The user then places the baseplate 2 over the stoma such that the stoma extends through the adhesive disc aperture 18.

[0162] The angled part 7” of the baseplate 2 has a thickness which is about 3.0 times greater than the thickness of the outer radial part 10.

[0163] The user then removes the collar release liner 15 and applies the flexible collar 13, adhering it to the skin further outward of the stoma, beyond the periphery of the mouldable adhesive disc 3, where skin is less sensitive. A fluid collection pouch can now be attached to the ostomy appliance 1 via the coupling component 5 and corresponding features on the fluid collection pouch. The user may insert one or more fingers or one or both hands into the annular space 11 and grip the finger grip 6 when coupling the fluid collection pouch to the coupling component 5 so that the force applied to the complimentary coupling part of the fluid collection pouch when coupling it to the coupling component 5 is exerted upon the finger grip and not against the user’s abdominal skin around the stoma. As such, the described embodiment reduces the pressure directly exerted upon the ostomate’s abdominal skin and facilitates the action of coupling and decoupling the fluid collection pouch, especially for users with limited dexterity.

[0164] Figures 2 to 13 each show further embodiments of the invention which share many features with that of figure 1. In figures 2 to 13, it should be noted that a number of features have been omitted for brevity. For example, features such as the hydrocolloid adhesive disc, aperture in the baseplate, baseplate release liner and collar have been omitted.

[0165] Figure 2 shows an embodiment of the invention comprising a baseplate 2a having an angled part comprising an angled inner surface 7a. The baseplate 2b further comprises an outer radial part 10a and a side wall 8a. From the base of the side wall 8a there is extending radially outwardly a finger grip 6a. The angled part of the baseplate 2a, outer radial part 10a, side wall 8a and finger grip 6a are each formed integrally. A coupling component 5a is bonded to the angled inner surface 7a of the baseplate 2a by adhesive bonding. The coupling component 5a is immovably coupled to the angled inner surface 7a of the baseplate 2a.

[0166] The angled part of the baseplate 2a has a thickness about 3.0 times greater than the thickness of the outer radial part 10a.

[0167] The finger grip 6a is angled away from the outer radial part 10a, and is angled with respect to the plane of the aperture in the baseplate 2a. The finger grip 6a is angled with respect to the plane of the aperture in the baseplate 2a at an angle of about 20°. The outer radial part 10a and the finger grip 6a define an annular space 1 la for a user to insert one or more fingers or one or both hands when coupling and decoupling a fluid collection bag from the baseplate 2a. Figure 3 shows an embodiment of the invention comprising a baseplate 2b having an angled part comprising an inner surface 7b. The baseplate 2b further comprises an outer radial part 10b and a side wall 8b. From the base of the side wall 8b there is extending radially outwardly a finger grip 6b. The finger grip 6b extends radially outwardly in the same plane as the plane of the aperture in the baseplate 2b such that the finger grip 6b and the outer radial part 10b, which is generally planar, are generally parallel to one another. A coupling component 5b also extends from the base of the side wall 8b. The outer radial part 10b and the finger grip 6b define an annular space 1 lb for a user to insert one or more fingers or one or both hands when coupling and decoupling a fluid collection bag from the baseplate 2b.

[0168] In this embodiment, each of the baseplate 2b, angled part of the baseplate 2b having inner surface 7b, outer radial part 10b, side wall 8b, finger grip 6b and coupling component 5b are integrally formed as a single component.

[0169] The angled part of the baseplate 2b has a thickness about 3.0 times greater than the thickness of the outer radial part 10b.

[0170] Figure 4 shows an embodiment of the invention comprising a baseplate 2c having an angled part comprising an inner surface 7c. The baseplate 2c further comprises an outer radial part 10c and a side wall 8c extending from the bottom of the inner surface 7c of the baseplate 2c. From the base of the side wall 8c there is extending radially outwardly a finger grip 6c. The finger grip 6c extends radially outwardly in the same plane as the plane of an aperture in the baseplate 2c such that the finger grip 6c and the outer radial part 10c, which is generally planar, are generally parallel to one another. The finger grip 6c extends slightly beyond a radially outer edge of the outer radial part 10c of the baseplate 2c. Beneficially, this increases the user’s ability to easily access the finger grip when coupling and decoupling a fluid collection pouch from the baseplate 2c.

[0171] A coupling component 5 c is arranged protruding from a lower surface of the finger grip 6c, away from the ostomate when in use. The outer radial part 10c and the finger grip 6c define an annular space 11c for a user to insert one or more fingers or one or both hands when coupling and decoupling a fluid collection bag from the baseplate 2c.

[0172] The angled part of the baseplate 2c has a thickness about 3.0 times greater than the thickness of the outer radial part 10c.

[0173] In this embodiment, each of the baseplate 2c, angled part of the baseplate 2c having inner surface 7c, outer radial part 10c, side wall 8c, finger grip 6c and coupling component 5c are integrally formed as a single component.

The baseplate 2d further comprises an outer radial part lOd and a side wall 8d extending from the bottom of the inner surface 7d of the baseplate 2d. From the base of the side wall 8d there is extending radially outwardly a finger grip 6d. The finger grip 6d extends radially outwardly in the same plane as the plane of an aperture in the baseplate 2d such that the finger grip 6d and the outer radial part lOd, which is generally planar, are generally parallel to one another.

[0175] The finger grip 6d extends slightly beyond a radially outer edge of the outer radial part lOd of the baseplate 2d. Beneficially, this increases the user’s ability to easily access the finger grip when coupling and decoupling a fluid collection pouch from the baseplate 2d.

[0176] A coupling component 5d is bonded to a lower surface of the finger grip 6d, with the attachment means of the coupling component facing away from the user when in use. The attachment means of the coupling component 5d are arranged in proximity to the base of the side wall 8d.

[0177] The outer radial part lOd and the finger grip 6d define an annular space lid for a user to insert one or more fingers or one or both hands when coupling and decoupling a fluid collection bag from the baseplate 2d.

[0178] The angled part of the baseplate 2d has a thickness about 3.0 times greater than the thickness of the outer radial part lOd. In this embodiment, each of the baseplate 2d, angled part of the baseplate 2d having inner surface 7d, outer radial part lOd, side wall 8d and finger grip 6d are integrally formed as a single component. The coupling component 5d may be bonded to the finger grip 6d by heat-welding, laser-bonding, ultrasonic welding or adhesive bonding.

The baseplate 2e further comprises an outer radial part lOe and a side wall 8e extending from the bottom of the inner surface 7e of the baseplate 2e. From the base of the side wall 8e there is extending radially outwardly a finger grip 6e. The finger grip 6e extends radially outwardly in the same plane as the plane of an aperture in the baseplate 2e such that the finger grip 6e and the outer radial part lOe, which is generally planar, are generally parallel to one another.

[0180] The finger grip 6e extends slightly beyond a radially outer edge of the outer radial part lOe of the baseplate 2e. Beneficially, this increases the user’s ability to easily access the finger grip when coupling and decoupling a fluid collection pouch from the baseplate 2e.

[0181] A coupling component 5e is bonded to a lower surface of the finger grip 6e, with the attachment means of the coupling component facing away from the user when in use. The coupling component 5e is bonded to the finger grip 6e at an approximate mid-point between the base wall 8e and an outer radial edge 6’e of the finger grip 6e.
