Abstract

Cover disc located in the area between a flange and the stoma is employed to periodically deliver a hydrocolloid containing ointment or non-aqueous paste to seal off the area around the stoma. Seepage of fluid passing from the stoma to a bag attached to the flange is absorbed by the ointment and prevented from weakening the adhesive bond attaching the flange to the skin.

Claims

1. A STOMAL DEVICE COMPRISING AN ADHESIVE MEMBER, A RIGID FLANGE MEANS INCLUDING A CONTINUOUS SIDE WALL, OUTWARDLY EXTEDING BOTTOM WALL PERPENDICULAR TO SAID SIDE WALL AND AN UPPER LIP, SAID FLANGE MEANS AFFIXED TO ONE SIDE OF SAID ADHESIVE MEMBER BY AN ADHESIVE BOND BETWEEN SAID BOTTOM WALL AND SAID ADHESIVE MEMBER, BATH SAID ASHESIVE MEMBER AND SAID BOTTOM WALL HAVING A CENTRALLY LOCATED OPENING TO PERMIT THE DEVICE TO ENCIRCLE A STOMA, A QUANTITY OF HYDROCOLLOID CONTAINING OINTMENT OR NON-AQUEOUSPASTE LOCATED INTERIOR OF SAID FLANGE SIDE WALL AND SUPPORTED BY SAID ADHESIVE MEMBER, A RIGID OR SEMI-RIGID COVERING DISC HAVING A CENTRALLY LOCATED OPENING SIZED AND SHAPED SO AS TO SNUGLY FIT IN THE SPACE BE-

2. The stomal device of claim 1 including a flexible stoma bag attached to said flange by means of an elastic band whereby said flange upper lip prevents accidental detachment of said bag.

3. The stomal device of claim 1 wherein said ointment or non-aqueous paste comprises an oil component selected from mineral oil or vegetable oil and from about 25 to about 75% by weight of a water soluble hydrocolloid, a water swellable hydrocolloid, or mixtures of water soluble and water swellable hydrocolloids.

4. The stomal device of claim 3 wherein said ointment or non-aqueous paste comprises from about 30 to about 55% by weight of hydrocolloid.

5. The stomal device of claim 3 wherein said cover disc is from about 1 to about 3 mm. thick and from materials which are resistant and compatible with the ingredients in the ointment or non-aqueous paste.

6. The stomal device of claim 1 wherein said adhesive member is a bonding composition comprising a pressure sensitive rubbery elastomer adhesive having intimately dispersed therein a water soluble or water swellable hydrocolloid.

7. The stomal device of claim 1 wherein said adhesive member is an adhesive disc comprising a polymer film or closed-cell plastic foam having a pressure sensitive adhesive coating on both sides.

8. The stomal device of claim 7 wherein the other side of said adhesive disc is attached to a peristomal covering comprising a bonding composition having a thin water insoluble backing film, said adhesive disc attached to said film.

9. The stomal device of claim 8 wherein said adhesive disc and said cover disc are circular and said peristomal covering is rectangular.

10. The stomal device of claim 8 including a flexible stoma bag attached to said flange by means of an elastic band whereby said flange upper lip prevents accidental detachment of said bag.

11. The stomal device of claim 10 wherein said ointment or non-aqueous paste comprises an oil component selected from mineral oil or vegetable oil and from about 25 to about 75% by weight of a water soluble hydrocolloid, a water swellable hydrocolloid, or a mixture of water soluble and water swellable hydrocolloids.

12. The stomal device of claim 11 wherein said ointment or non-aqueous paste comprises from about 30 to about 55% by weight of hydrocolloid.

13. The stomal device of claim 12 wherein said cover disc is from about 1 to about 3 mm. thick and from materials which are resistant and compatible with the ingredients in the ointment or non-aqueous paste.
