Abstract

An ostomy appliance comprising an adhesive wafer (100), which comprises a first, a second and a third zone (102, 104, 106). The third zone defines at least a part of the outer rim (110) of the adhesive wafer and the second zone encirculates the first zone.

Claims

1. An ostomy appliance for attachment to a stoma, the ostomy appliance comprising:

an adhesive wafer having an outer rim, and an inner rim which is defined by a passage for receiving a stoma of a user, the adhesive wafer comprising a backing layer and a skin facing adhesive layer; and

a collecting bag which in use is secured to the adhesive wafer;

wherein the adhesive wafer in a first zone has a first set of properties and in a second zone has a second set of properties and in a third zone has a third set of properties;

wherein at least a part of the first zone is defined between the inner rim and the second zone; and

the third zone is defined between the outer rim and the second zone, wherein the thickness of the third zone is at least 50% higher than the thickness of the second zone.

2. An ostomy appliance according to claim 1, wherein the first zone is encirculated by the second zone.

3. An ostomy appliance according to any of the preceding claims, wherein a first part of the outer rim of the adhesive wafer is defined by the second zone and a second part of the rim is defined by the third zone.

4. An ostomy appliance according to claim 3, wherein a circumferential length of the first part of the rim is at least three times the circumferential length of second part of the rim.

5. An ostomy appliance according to any of the preceding claims, wherein the first and third set of properties are identical.

6. An ostomy appliance according to any of the preceding claims, wherein the first and the second set of properties are identical.

8. An ostomy appliance according to any of the preceding claims, wherein one or more of the first, second and third zones are defined by the backing layer.

9. An ostomy appliance according to any of the preceding claims, wherein one or more of the first, second and third set of properties comprise one or more of:

a thickness of the first and/or second and/or third zone, or a tear strength of the first and/or the second and/or the third zone, or a stiffness of the first and/or second and/or third zone.

10. An ostomy appliance according to any of the preceding claims, wherein at least a part of a transition line between the second and the third zone is provided with a notch.
