Abstract
A controlled evacuation ostomy appliance comprises a membrane that is urged into sealing engagement with a stoma, by the generation of radial tension in the membrane. A tensioning device applies tension, with respect to the stoma, at one or more positions that are (i) outboard of the periphery of the projecting portion of the stoma, and/or (ii) between the level of the peristomal skin and the level of the most projecting part of the stoma. Tension limiting means are disclosed. The membrane may be gas-permeable to allow flatus to be vented.
Claims25
A controlled evacuation ostomy appliance comprising:
- a. a frame having a stomal aperture;
- b. a membrane located inside said frame, in the region of said stomal aperture, and configured for contacting a stoma of a wearer to obstruct the discharge of at least solid body waste therefrom;
- and
- c. a tensioning device for generating tension in the membrane, at least in use when the appliance is fitted to a stoma, the tension being in a direction to urge the membrane towards the stomal aperture.
A controlled evacuation ostomy appliance, comprising a membrane for forming a seal against a wearer's stoma, and wherein, in use, the membrane is tensioned in a concave configuration with respect to the stoma.
A controlled evacuation ostomy appliance comprising a tensioning device for urging a membrane into sealing engagement with a stoma, in use, by creating radial tension in the membrane.
