Body waste collecting device
A device for collection waste from a body includes a collecting pouch and an adhesive wafer connected to the collecting pouch for attaching the collecting pouch to the body. The adhesive wafer includes at least one intermediate layer of adhesive, a skin facing layer of adhesive, a first film layer, and a second film layer. The first film layer is formed of backing layer material, and is positioned between the skin facing layer of adhesive and the intermediate layer of adhesive. The second film layer is formed of backing layer material. The second film layer is positioned adjacent to the intermediate layer of adhesive on an opposite side of the intermediate layer of adhesive from the first film layer. The first film layer is configured to reduce a peel force of the adhesive wafer.
1. A device for collecting waste from a body, the device comprising:
an adhesive wafer for attaching to the body, the adhesive wafer including:
at least one intermediate layer of adhesive;
a skin facing layer of adhesive having a thickness in a range between 25 and 200 μm;
a film layer positioned between the skin facing layer of adhesive and the intermediate layer of adhesive; and
a backing layer positioned adjacent to the intermediate layer of adhesive on an opposite side of the intermediate layer of adhesive from the film layer; and
a collecting pouch attachable to the backing layer;
wherein the backing layer and the film layer are formed of the same material and the film layer is configured to reduce a peel force of the adhesive wafer.
2. The device of claim 1 , wherein the backing layer and the film layer are permeable to moisture, and wherein the permeability of the film layer is above 1000 g/m 2 /24 h.
3. The device of claim 1 , wherein the backing layer and the film layer are foamed film layers.
4. The device of claim 1 , wherein the material forming the backing layer and the film layer includes at least one of ethylene vinyl acetate, polyurethane, or polyethylene.
5. The device of claim 1 , wherein the intermediate layer of adhesive and the skin facing layer of adhesive include liquid impermeable, moisture permeable soft adhesives.
6. The device of claim 5 , wherein the intermediate layer of adhesive has a water absorption capacity of more than 15% in weight at equilibrium and the skin facing layer of adhesive has a water absorption capacity of less than 8% in weight at equilibrium.
7. The device of claim 1 , wherein the intermediate layer of adhesive and the skin facing layer of adhesive are formed of the same adhesive material.
8. The device of claim 1 , wherein the skin facing layer of adhesive has a thickness that is less than 33% of a thickness of the intermediate layer of adhesive.
