Abstract

A body fitment for an ostomy appliance comprises an adhesive wafer including a body-facing side for adhesively contacting the user'"'"'s body. The adhesive wafer includes a moldable region shapable by the user, and a hole therethrough for allowing the user to manually mold a stomal aperture in the moldable region. The body fitment is provided with the inner peripheral region of the adhesive bordering the hole being pre-shaped with a non-planar configuration, e.g. bent or curled away from the body-facing side of the adhesive, prior to be being molded by the user. The pre-shaped, non-planar, configuration is supported by a release device that initially protects the body-facing side of the adhesive but which is intended to be removed prior to use of the body fitment, to enable the adhesive then to be molded by a user.

Claims

1. An adhesive body fitment for attaching an ostomy appliance to a wearer'"'"'s body, the body fitment comprising:

a. an adhesive wafer including a body-facing side for adhesively contacting the wearer'"'"'s body, the adhesive wafer further including;

a moldable shapable region having a hole therethrough for allowing manual molding of a stomal aperture in said moldable region, the inner peripheral region of the adhesive bordering the hole having a non-planar configuration; and

b. a removable release device fitted to the body-facing side of the adhesive wafer, the release device including a support for maintaining the non-planar configuration of the inner peripheral region of the adhesive bordering the hole, until said release device is removed prior to molding of the moldable region of the adhesive.

2. The adhesive body fitment according to claim 1, wherein the inner peripheral region of the adhesive bordering the hole bends to extend in a direction away from said body-facing side of said adhesive, and said support is shaped for supporting said inner peripheral region of the adhesive in the bent configuration.

3. The adhesive body fitment according to claim 2, wherein the inner peripheral region of the adhesive bordering said hole at least partly curls away from said body-facing side of the adhesive, and said support is shaped for supporting said inner peripheral region of the adhesive in the at least partly curled configuration.

4. The adhesive body fitment according to claim 3, wherein the inner peripheral region of the adhesive has a configuration selected from frusto-conical;

flared;

partly curled, and said support is shaped for supporting said inner peripheral region in said configuration.

5. The adhesive body fitment according to claim 1, wherein the adhesive wafer has a generally uniform thickness.

6. The adhesive body fitment according to claim 1, wherein the moldable region of the adhesive is integral with the remainder of the adhesive wafer.

7. The adhesive body fitment according to claim 1, wherein the release device comprises a single member including said support.

8. The adhesive body fitment according to claim 1, wherein the release device is made of, or is coated with, a material to which the adhesive of the wafer does not strongly adhere.

9. The adhesive body fitment according to claim 1, wherein the adhesive wafer further includes a constrained-shape region surrounding the moldable region, the constrained-shape region being (i) substantially less shapeable than the shapeable region;

or (ii) of substantially fixed shape.

10. The adhesive body fitment according to claim 9, further comprising a shape-defining member provided on the opposite side of the adhesive wafer to said body-facing side, said shape defining member constraining the shape of said constrained-shape region of the adhesive.

11. The adhesive body fitment according to claim 10, wherein the shape-defining member is substantially planar.

12. The adhesive body fitment according to claim 10, wherein the shape-defining member is substantially non-planar.

13. An ostomy appliance comprising an adhesive body fitment for attaching the ostomy appliance to a wearer'"'"'s body, the body fitment comprising:

a. an adhesive wafer including a body-facing side for adhesively contacting the wearer'"'"'s body, the adhesive wafer further including;

a moldable shapable region having a hole therethrough for allowing manual molding of a stomal aperture in said moldable region, the inner peripheral region of the adhesive bordering the hole having a non-planar configuration; and

b. a removable release device fitted to the body-facing side of the adhesive wafer, the release device including a support for maintaining the non-planar configuration of the inner peripheral region of the adhesive bordering the hole, until said release device is removed prior to molding of the moldable region of the adhesive.

14. The ostomy appliance according to claim 13, wherein the ostomy appliance is a one-piece appliance.

15. The ostomy appliance according to claim 13, wherein the ostomy appliance is a two-piece appliance.

16. An assembly comprising:

a. a package for supply to a user; and

b. ostomy equipment contained in said package, said ostomy equipment including an adhesive body fitment for attaching an ostomy appliance to a wearer'"'"'s body, the body fitment comprising;

an adhesive wafer including a body-facing side for adhesively contacting the wearer'"'"'s body, the adhesive wafer further including a moldable shapable region having a hole therethrough for allowing manual molding of a stomal aperture in said moldable region, and at least an inner peripheral portion of the moldable region bordering said hole being pre-shaped with a non-planar configuration in which said adhesive extends in a direction away from said body-facing side of the adhesive, to facilitate molding.

17. The assembly according to claim 16, wherein the package is sterile inside.

18. The assembly according to claim 16, wherein the package is hermetically sealed in a closed condition.

19. The assembly according to claim 16, wherein the ostomy equipment comprises a one-piece ostomy appliance to which said adhesive body fitment is permanently attached.

20. The assembly according to claim 16, wherein the ostomy equipment is a two-piece ostomy appliance in which said body fitment is a releasably attachable component.

21. A method for adhering an ostomy pouch to a wearer, the steps comprising:

providing an ostomy pouch with a body fitment wherein the body fitment includes an adhesive wafer having a body-facing side for adhesively contacting the wearer'"'"'s body, the wafer including a moldable shapeable region having a hole therethrough, and a removable release cover fitted to the body-facing side of the adhesive wafer around the hole;

molding the moldable shapeable region of the wafer with said removeable release cover in place; and

subsequently removing the removable release cover from said adhesive wafer.
