Abstract
A base plate of an ostomy appliance includes a film, an adhesive disposed on a proximal surface of the film, an annular ring connected to the distal surface of the film, and a release liner removably attached to the adhesive. A stoma-receiving through-going hole is formed through the film and the adhesive and the release liner. A first section of the base plate extends radially from the stoma-receiving through-going hole to a second section of the base plate, and the second section extends radially from the first section to an outermost perimeter edge of the base plate. The base plate is formed to have a heat-set curvature such that a proximal side of the second section is convex and a distal side of the second section is concave relative to the annular ring.
Claims16
An ostomy appliance comprising a base plate, the base plate comprising:
- a film including a distal surface opposite from a proximal surface;
- an annular ring connected to the distal surface of the film and adapted to couple with a waste collection bag;
- an adhesive disposed on the proximal surface of the film;
- a release liner removably attached to the adhesive;
- and
- a stoma-receiving through-going hole formed through the film and the adhesive and the release liner at a location inside of the annular ring, with a first section of the base plate extending radially from the stoma-receiving through-going hole to a second section of the base plate, and the second section extending radially from the first section to an outermost perimeter edge of the base plate;
- wherein the base plate is formed to have a heat-set curvature such that a proximal side of the second section is convex when the base plate is viewed from a proximal direction and a distal side of the second section is concave when the base plate is viewed from a distal direction,
- wherein the base plate is invertible away from the heat-set curvature to provide the proximal side of both the first section and the second section with a concave curvature when the base plate is viewed from the proximal direction.
