Abstract

An ostomy appliance comprises a body-attachable pad of skin-compatible adhesive material having a stomal orifice, and means whereby a plurality of ostomy bags can be attached in sequence to the pad by exposing a fresh region of adhesive each time it is desired to attach a clean ostomy bag.

Claims

1. An ostomy appliance comprising a bag for receiving discharged wastes, a stomal orifice in one wall of the bag to receive a stoma of a patient, a flange having a flat surface, intended to face towards the body of the wearer when the appliance is worn, surrounding the orifice, a medical grade adhesive pad, and a stack of double sided adhesive annuli, one on top of the other, for attaching the flange of the bag to the pad, said stack of annuli interleaved with peelable cover annuli, said stack and cover annuli carried by the pad and adapted to encircle the patient'"'"'s stoma, each of the double sided adhesive annuli having a peripherally projecting portion.

2. The appliance of claim 1 wherein said double sided adhesive annuli have a gradually diminishing outside diameter with the annuli closest to the pad having the smallest diameter and the annuli farthest from the pad, the largest.

3. The appliance of claim 2 wherein the outside diameter of each of said annuli is greater than that of the associated cover layer.

4. An ostomy appliance comprising a bag for receiving discharged wastes, a stomal orifice in one wall of the bag to receive a stoma of a patient, a medical grade adhesive pad, and a stack of peelable annular member, one on top of the other and carried by said pad for attaching the bag to the pad and adapted to encircle the patient'"'"'s stoma, each having a layer of adhesive on one side thereof and a peripherally projecting portion.

5. The appliance of claim 4 wherein the peripherally projecting portions of adjacent members are angularly spaced apart from one another.

6. The ostomy appliance of claim 4 wherein the peripherally projecting portion comprises an opening therethrough.

7. The ostomy appliance of claim 4 wherein said appliance further comprises a microporous tape attached to said medical grade adhesive pad for aiding in the attachment of said appliance to the body of the wearer.

12. The appliance of claim 4 wherein said peripherally projecting portions are arranged so that peeling off a first peripheral portion exposes a second pheripheral portion, the latter not being accessible to the user until the first peripheral portion has been peeled off.

8. A body-attachable pad carrying a flange to which is adhesively secured a stack of sequentially peelable adhesive annular members, one on top of the other, for attaching an ostomy bag having a stomal orifice to receive a stoma of a patient to the flange, said annular members adapted to encircle the patient'"'"'s stoma, and the flange and the pad are connected by a flexible web which permits limited relative movement therebetween in a direction substantially perpendicular to the pad, whereby an ostomate can place his/her fingers behind the flange, between the flange and his body, so as to absorb the pressure which is applied to fix the bag to the exposed one of the stack of adhesive annular members.

9. An ostomy appliance comprising a bag for receiving discharged wastes, a stomal orifice in one wall of the bag for receiving a stoma of a patient, a washer attached to the wall of the bag and having a flat surface intended to face towards the body of the wearer when the appliance is worn and an inner edge surrounding the periphery of said stomal orifice, a medical grade adhesive pad carrying a flange having an inner peripheral rib which encircles the stoma of the patient, and adhesive means for adhesively attaching said bag to said flange, said bag wall extending inwardly of the inner edge of said washer surrounding said stomal orifice to contact the the rib on its surface opposite the stoma, said adhesive means comprising a plurality of peelable annular members having an adhesive layer on at least one side thereof and carried by said pad, said annular members adapted to surround the patient'"'"'s stoma.

10. The appliance of claim 9 wherein said a plurality of peelable annular members comprises at least seven members.

11. The appliance of claim 9 wherein said appliance further comprises:

a layer of self adhesive fabric placed between said flange and said plurality of peelable annular members.
