Description

[0001] Ostomy Pouch Accessory

[0002] Technical Field of the Invention

[0003] The present invention relates to an ostomy coupling, in particular to an ostomy body fitment, such as a base plate, for attaching an ostomy pouch to an ostomate.

[0004] Background to the Invention

[0005] When using an ostomy appliance, it is paramount that the ostomy appliance is securely attached to the user’s body around the stoma in a manner that it can efficiently receive and collect stomal output. It is particularly important that leaks of liquid and / or gas are prevented / minimised as nay leaking can cause discomfort or injury, such as skin damage around the stoma, and presents a hygienic risk to the user as well as potential embarrassment and inconvenience.

[0006] Typically, an ostomy appliance comprises a pouch in fluid communication with the stoma via a hydrocolloid adhesive component, sometimes referred to as a flange that attaches the ostomy appliance to teh skin of the user around the stoma. Conventionally, the hydrocolloid adhesive flange is attached to the pouch directly via an adhesive or weld, such as a heat weld or ultra-sonic weld; this is known in the art as a “one-piece pouch”.

[0007] US 2004 / 0006320 Al shows an example of a hydrocolloid adhesive flange on an ostomy pouch. The hydrocolloid adhesive flange is comprised of two layers of adhesive with a film layer sandwiched between with a hole extending therethrough for the stoma to pass through. The flange can be shaped by rolling and / or folding to increase the diameter of the hole, due to the materials chosen for the adhesive and film layers the flange will, when released, partially return to their original shape thereby sealing against the stoma.

[0008] In certain circumstances, it is beneficial to control the shape of the hydrocolloid adhesive component to enhance transport of stomal output into the pouch and provide a better seal between the user and the ostomy appliance. To achieve ths, a shaped-disc that is more rigid than the hydrocolloid adhesive component is attached to the hydrocolloid adhesive; for example a convex disc may be provided for users with a recessed stoma (known in the art as a “convex baseplate”). Removal of the adhesive component (and flexible collar where present) from the skin of the user to replace the baseplate may be uncomfortable, for this reason, and to reduce waste, it is therefore desirable to reduce the frequency at which the baseplate is replaced.

[0009] Furthermore, it is desirable that the pouch, and means by which it is attached, be as low profile as possible, thereby providing a more discrete and comfortable appliance.

[0010] 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 or alternative ostomy appliance.

[0052] Detailed Description of the Invention

[0053] In order that the invention may be more clearly understood one or more embodiments thereof will now be described, by way of example only, with reference to the accompanying drawings, of which:

[0054] Figure 1 shows a cross-sectional view of an adhesive body fitment of the prior art;

[0055] Figure 2 shows a cross-sectional view of a first adhesive body fitment according to a of the present invention;

[0056] Figure 3 shows a cross-sectional view of the adhesive body fitment of Figure 2 attached to an ostomy pouch; and

[0057] Figure 4 shows a cross-sectional view of a second adhesive body fitment according to the present invention. Prior Art

[0058] With reference to Figure 1 an adhesive body fitment 101 of the prior art is described. The adhesive body fitment 101 comprises a shaped-disc in the form of a rigid convex disc 109.

[0059] Laminated to an outer face of the disc 109 is an adhesive component for coupling the adhesive body fitment 101 to the abdomen of the wearer around a stoma. This takes the form of a mouldable hydrocolloid adhesive ring 102 comprised of a first adhesive layer 104, a second adhesive layer 105 and an elastic film layer 106 arranged between the two adhesive layers. Arranged at the centre of the adhesive ring 102 in a stoma aperture 103.

[0060] The hydrocolloid adhesive ring 102 extends to the radially outer edge of the disc 109, it also extends radially inward over the disc such that apart from at the stoma aperture 103 arranged centrally on the hydrocolloid adhesive ring 102, the hydrocolloid adhesive disc 19 occludes the central opening of the disc 109. The stoma aperture 103 is sized such that is has a smaller diameter than the typical stoma (not shown).

[0061] Arranged on the surface of the hydrocolloid adhesive ring opposing that which is laminated to the rigid disc 109 (hereafter surfaces in this orientation will be referred to as “upper surfaces”) is a ring release liner 107 which extends across the entire surface of the hydrocolloid adhesive disc 102.

[0062] Arranged on the opposing side of the rigid disc 109 to the hydrocolloid adhesive ring 102 and extending circumferentially around it is a flexible collar 111. The collar 111 is formed of a sheet of woven material having a ring shape. The inner edge has a circular shape and is sized such that the collar 111 overlaps the outer periphery of the rigid disc 109. An upper surface of the collar 111 is provided with an adhesive coating, for example an acrylic adhesive coating and a collar release liner 112 which is releasably adhered to the acrylic adhesive coating.

[0063] Opposing the rigid disc 109 on the collar 111 is an attachment point 113, in one- piece pouches a wall of the ostomy pouch, or an intervening layer is bonded to the attachment point 113, in two-piece ostomy pouch a coupling component is provided for coupling to a corresponding coupling component on the ostomy pouch. The coupling component could be a mechanical component, for example a snap fit ring, or an adhesive component.

[0064] In use, the wearer removes the ring release layer 107 and proceeds to shape the mouldable adhesive ring 102 by rolling or folding the ring such that the second adhesive layer adheres to itself, and thereafter the first adhesive layer 104 adheres to the second adhesive layer 105. In this way the stoma aperture 103 can be increased in diameter allowing the fitment to be placed over the stoma and the first adhesive layer 104 adheres to the wearer peristomally. Once the fitment has been positioned the mouldable adhesive ring 102 is allowed to partially return to its original size and shape, and seals against the stoma. This partial return to its original shape is achieved due to the elastic properties of the film layer 106. The wearer then removes the collar release liner 112 and adheres the wearer’ s skin surrounding the stoma outwards of the adhesive fitment where skin is less sensitive. Where the adhesive body fitment 101 is part of a two-piece pouch, then the ostomy pouch may now be attached to the fitment.

[0065] The collar 111 provides a means to support the ostomy pouch on the wearer away from the more sensitive stoma, this improves the comfort of the wearer.

[0066] First Embodiment

[0067] With reference to Figures 2 and 3, an adhesive body fitment 1 according to a first embodiment of the present invention is described, the adhesive body fitment 1 of the present invention shares a number of features with the adhesive body fitment of the prior art and like features are provided with like reference numerals, decreased by 100. The adhesive body fitment 1 comprises a shaped-disc in the form of a rigid convex disc 9. The rigid convex disc 9 is comprised of an annular planar portion 9a and a tapering portion 9b. The annular planar portion 9a of the rigid convex disc 9 defines a reference plane A-A relative to which further directions of the following description will be made. The tapering portion 9b extends radially inward and away from the plane A-A from a radially inner edge 9a’ of the planar portion 9a. The convex disc 9 is thereby provided with a central opening 10.

[0068] Laminated to an outer face 9’ of the disc 9 is an adhesive component 2 for coupling the adhesive body fitment 1 to the abdomen of the wearer around a stoma. The adhesive component 2 takes the form of a mouldable hydrocolloid adhesive ring 2 comprised of a first adhesive layer 4, a second adhesive layer 5 and a (preferably elastic) film layer 6 arranged between the two adhesive layers 4,5. Arranged at the centre of the adhesive ring 2 in a stoma aperture 3 for receiving the stoma.

[0069] As the mouldable hydrocolloid adhesive ring 2 is laminated to the convex disc 9 it also has a convex cross-sectional profile to suit recessed stomas, flush stomas, stomas which are arranged in skin folds / creases, or protrude from soft / flaccid abdomens

[0070] The hydrocolloid adhesive ring 2 extends to the radially outer edge 9a” of the disc 9, it also extends radially inward over the disc such that apart from at the stoma aperture 3 arranged centrally on the hydrocolloid adhesive ring 2, the hydrocolloid adhesive disc 9 occludes the central opening 10 of the disc. The stoma aperture 3 is sized such that is has a smaller diameter than the typical stoma (not shown).

[0071] The first adhesive layer 4 and film layer 6 extend laterally (that is in a plane parallel to A-A and where the lateral extent is measured along a line from the centre of the first adhesive layer - which may be within the stoma aperture, or the centre thereof - and a peripheral edge of the first adhesive layer) beyond a radially outer edge 5’ of the second adhesive layer 5. The portion of the first adhesive layer 4 and film layer 6 which is beyond the second adhesive layer 5 forms a collar 20. In this embodiment the collar 20 has an outer periphery with an elliptical shape having a major axis of 141mm and a minor axis of 120 mm. The use of an elliptical shape means more material can be provided above and below the stoma where additional adhesion is more useful. However, in other embodiments it may have alternative shapes, for example circular.

[0072] The second adhesive layer 5 has a circular shape, in this embodiment having a diameter of 90 mm, as such the extent by which the first adhesive layer 4 (and film layer 6) extends beyond the second adhesive layer is between 15 and 25 mm, depending upon where on the ellipse it is measured.

[0073] Arranged on the surface of the first adhesive layer 4 opposing that which is laminated to the film layer 6 (hereafter surfaces in this orientation will be referred to as “upper surfaces”) is a ring release liner 7 which extends across the entire surface of the hydrocolloid adhesive disc 2 and collar 20. With reference to Figure 3 the body fitment is shown mounted on an ostomy pouch 30 in a “one-piece” configuration. The ostomy pouch 30 comprises a first, body facing wall 31 and a second wall 32, the two walls being joined about their periphery to form a cavity 33 for storing stomal output. The first wall 31 comprises an opening 34 which is aligned with the fitment 1 with the fitment being bonded (or adhered) about the opening 34 to seal the opening.

[0074] In use, the wearer removes the ring release liner 7 and proceeds to shape the mouldable adhesive ring 2 by rolling or folding the ring from the stoma aperture 3 such that the second adhesive layer 5 adheres to itself, and thereafter the first adhesive layer 4 adheres to the second adhesive layer 5. In this way the stoma aperture 3 can be increased in diameter allowing the fitment 1 to be placed over the stoma and the first adhesive layer 4 adheres to the wearer peristomally. Once the fitment has been positioned the mouldable adhesive ring 2 is allowed to partially return to its original size and shape wherein the stoma aperture 3 seals against the stoma. This partial return to its original shape is achieved due to the elastic properties of the film layer 6. The wearer then continues to press the collar 20 against their skin adjacent to the stoma such that the collar adheres to the skin and distributes the weight of the ostomy appliance over a greater area, increasing comfort. As compared to the adhesive body fitments of the prior art, the adhesive body fitment of the first embodiment is advantageous as it provides a less bulky fitment, improving the comfort and making wearing the ostomy appliance more discrete. The ostomy appliance is also easier to apply as only a single adhesive component needs to be applied with a single release liner. Furthermore, the appliance requires less material and steps to manufacture, this also reduces the volume of material sent to landfill when the ostomy appliance is disposed of.

[0075] Second Embodiment

[0076] With reference to Figure 4, an adhesive body fitment 51 according to the present invention is described, the adhesive body fitment 51 of the present embodiment shares a number of features with the adhesive body fitment of the first embodiment and like features are provided with like reference numerals, advanced by 50. The adhesive body fitment 51 comprises a shaped-disc in the form of a rigid disc 59. The rigid disc 59 has an annular planar profile and comprises a central opening 60. The rigid disc 59 also defines a plane B-B relative to which other directions are described here within.

[0077] Laminated to an outer face 59’ of the disc 59 is an adhesive component 52 for coupling the adhesive body fitment 51 to the abdomen of the wearer around a stoma. The adhesive component 52 takes the form of a mouldable hydrocolloid adhesive ring 52 comprised of a first adhesive layer 54, a second adhesive layer 55 and a (preferably elastic) film layer 56 arranged between the two adhesive layers 54,55. Arranged at the centre of the adhesive ring 52 in a stoma aperture 53 for receiving the stoma.

[0078] The hydrocolloid adhesive ring 52 extends to the radially outer edge 59a” of the disc 59, it also extends radially inward over the disc such that apart from at the stoma aperture 53 arranged centrally on the hydrocolloid adhesive ring 52, the hydrocolloid adhesive disc 59 occludes the central opening 60 of the disc. The stoma aperture 53 is sized such that is has a smaller diameter than the typical stoma (not shown).

[0079] The first adhesive layer 54 and film layer 56 extend laterally (that is parallel to the plane B-B) beyond a radially outer edge 55’ of the second adhesive layer 55. The portion of the first adhesive layer 54 and film layer 56 which is beyond the second adhesive layer 55 forms a collar 70. In this embodiment the collar 70 has an outer periphery with an elliptical shape having a major axis of 141 mm and a minor axis of 120 mm the use of an elliptical shape means that more material can be provided above and below the stoma where additional adhesion is more useful. However in other embodiments it may have alternative shapes, for example circular.

[0080] The second adhesive layer 55 has a circular shape, in this embodiment having a diameter of 90 mm, as such the extent by which the first adhesive layer 4 (and film layer 6) extends beyond the second adhesive layer 5 is between 15 and 25 mm, depending upon where on the ellipse it is measured.

[0081] Arranged on the surface of the first adhesive layer 54 opposing that which is laminated to the film layer 56 (hereafter surfaces in this orientation will be referred to as “upper surfaces”) is a ring release liner 57 which extends across the entire surface of the hydrocolloid adhesive disc 52 and collar 70. On the opposing side of the rigid disc 59 to the mouldable adhesive ring 52 is a coupling component 63, as the adhesive body fitment is for a two-piece ostomy pouch the coupling component is provided for coupling to a corresponding coupling component on the ostomy pouch (not shown). In this embodiment the coupling component is a snap fit ring, however other a mechanical components, or an adhesive component could be used in alternatives.

[0082] In use, the wearer removes the ring release liner 57 and proceeds to shape the mouldable adhesive ring 52 by rolling or folding the ring from the stoma aperture 53 such that the second adhesive layer 55 adheres to itself, and thereafter the first adhesive layer 54 adheres to the second adhesive layer 55. In this way the stoma aperture 53 can be increased in diameter allowing the fitment 51 to be placed over the stoma and the first adhesive layer 54 adheres to the wearer peristomally. Once the fitment has been positioned the mouldable adhesive ring 52 is allowed to partially return to its original size and shape wherein the stoma aperture 53 seals against the stoma. This partial return to its original shape is achieved due to the elastic properties of the film layer 56. The wearer then continues to press the collar 70 against their skin adjacent to the stoma such that the collar adheres to the skin and distributes the weight of the ostomy appliance over a greater area, increasing comfort.

[0083] As compared to the adhesive body fitments of the prior art, the adhesive body fitment of the first embodiment is advantageous as it provides a less bulky fitment, improving the comfort and making wearing the ostomy appliance more discrete. The ostomy appliance is also easier to apply as only a single adhesive component needs to be applied with a single release liner. Furthermore, the appliance requires less material and steps to manufacture, this also reduces the volume of material sent to landfill when the ostomy appliance is disposed of.

[0084] The one or more embodiments are described above by way of example only. Many variations are possible without departing from the scope of protection afforded by the appended claims.
