Abstract
Disclosed is a base plate 1 for an ostomy collection device, comprising a cover layer 2 whereon an adhesive layer 3 is at least partly disposed. Immediately surrounding a through-going hole 6, the base plate has an inner area wherein the cover layer extends beyond the adhesive layer in a radial direction toward the through-going hole, thereby providing an overlap 7 protecting the adhesive material from contact with stomal output.
Claims13
A base plate for an ostomy appliance, the base plate comprising:
- an adhesive layer having a skin facing side, configured to be attached to a skin surface of the user around a stoma, and an opposite backing side, the adhesive layer comprising a first adhesive and a second adhesive surrounding the first adhesive, the first adhesive includes an absorbent compound such as to provide fast swelling properties and the second adhesive being different from the first adhesive;
- a stoma-receiving hole extending through the first adhesive from the skin facing side to the backing side along longitudinal axis A-A;
- and
- a backing layer secured to the backing side of the adhesive layer, with an aperture formed in the backing layer to have an aperture diameter that is smaller than a diameter of the stoma-receiving hole before the base plate is applied to a user, the aperture is located over the stoma-receiving hole of the adhesive layer to provide the base plate with a sealing flange that overlaps some but not all of the stoma-receiving hole, the sealing flange forming a circular, planar member substantially parallel to the skin facing side of the adhesive surface;
- wherein the sealing flange is configured to provide a barrier preventing the first adhesive from contact with stomal effluents and preventing the first adhesive from expanding in an axial direction along axis A-A.
