Abstract

An adhesive mount for adhesively attaching an ostomy bag about the stoma of a patient which comprises a layer of moisture vapor transmitting plastics foam and a layer of moisture vapor transmitting pressure sensitive adhesive in juxtaposition therewith and an ostomy bag device having an adhesive mount bonded about an aperture thereof is described.

Claims

1. An ostomy bag device which comprises an ostomy bag having an aperture adapted to receive the stoma of a patient, an apertured adhesive mount bonded to the bag about said aperture, said adhesive mount comprising a layer of a moisture vapour transmitting plastics foam and a layer of a moisture vapour transmitting pressure sensitive adhesive.

2. An ostomy bag device as claimed in claim 1 in which the moisture vapour transmitting foam comprises a polyurethane.

3. An ostomy bag device as claimed in claim 1 in which the moisture vapour transmitting plastics foam is a reticulated foam.

4. An ostomy bag device as claimed in claim 1 in which the moisture vapour transmitting adhesive layer is continuous.

5. An ostomy bag device as claimed in claim 2 in which the continuous adhesive layer comprises a polyvinyl ethyl ether.
