Ostomy appliance
First Claim
1. A floatable coupling unit for an ostomy coupling for releasably attaching an ostomy appliance to a body fitment, the floatable coupling unit comprising:
- a coupling part for releasable attachment to a complementary appliance-side coupling part; and
a flexible support collar extending from the coupling part for supporting the coupling part, the flexible support collar permitting floatable displacement of the coupling part, and being configured to hold the coupling part stably in (i) an extended position and (ii) a retracted position;
by means of internal stress in the material of the flexible support collar.

Abstract
An ostomy coupling is disclosed comprising a floatable coupling part. The coupling part is supported with respect to an adhesive wafer by means of a flexible support collar that permits displacement of the coupling part in a floatable manner. The flexible collar comprises plastics film and has bistable shapes. The collar is configured to hold the coupling part stably in (i) an extended position spaced from the adhesive wafer, to facilitate an ostomate to manually brace the coupling part in order to relieve the attachment force when an ostomy appliance is press fitted to the coupling part, and (ii) in a retracted position close to the adhesive wafer.

13. An ostomy coupling comprising:
-
an appliance-side coupling part having an orifice therethrough; a body-fitment-side coupling part having an orifice therethrough; and a flexible support collar extending from the body-fitment-side coupling part for supporting the body-fitment-side coupling part, the flexible support collar permitting displacement of the body-fitment-side coupling part, and being configured to hold the body-fitment-side coupling part stably in (i) an extended position for permitting a user manually to brace the body-fitment-side coupling part to relieve an attachment force when the coupling parts are pressed into engagement, and (ii) in a retracted position;
by means of internal stress in the material of the flexible support collar. - View Dependent Claims (14)

15. An ostomy body fitment for releasably mounting an ostomy appliance, the body fitment comprising:
-
an adhesive wafer for adhesive attachment to skin; a coupling part for releasably attaching to a complementary coupling part of an ostomy appliance; and a flexible support collar for supporting the coupling part with respect to the adhesive wafer, the flexible support collar extending from the coupling part and being joined directly or indirectly to the adhesive wafer, the flexible support collar permitting floatable displacement of the coupling part with respect to the adhesive wafer, and being configured to hold the coupling part stably in (i) an extended position and (ii) a retracted position;
by means of internal stress in the material of the flexible support collar. - View Dependent Claims (16)

17. A method of supporting a coupling part in a floatable manner with respect to an adhesive wafer of an ostomy body fitment, the method comprising:
providing a flexible support collar between the adhesive wafer and the coupling part, the flexible support collar permitting floatable displacement of the coupling part with respect to the adhesive wafer, and being configured to hold the coupling part stably in (i) an extended position and (ii) a retracted position;
by means of internal stress in the material of the flexible support collar.

18. A bistable support for a coupling part of an ostomy coupling, the bistable support having a through passage and first and second interface regions, the first interface region being connected to the coupling part, and the second interface region being secured or securable, directly or indirectly, to an adhesive wafer, the bistable support being configured to hold the coupling part stably in (i) an extended position in which the first and second interface regions are substantially spaced apart in an axial direction of the through passage, and (ii) in a retracted position;
- by means of internal stress in the material of the flexible support collar in which the first and second interface regions are positioned closer together in the axial direction.
