ABSTRACT:
An ostomy equipment is described which comprises in combination a flat bandage to be adhesively affixed to the wearer's abdomen around an intestinal opening, an ostomy bag and two-part ring coupling to releasably attach the bag to the bandage. The two annular members of the ring coupling have co-operating annular profile components to ensure tightening, and co-operating annular projections with annular engaging faces substantially parallel with the bandage to counteract unintentional release. The connection between the bag and its annular coupling member is situated in its entirety radially within the co-operating engaging faces of the annular coupling members; this is a safeguard against leakage in case of a one-sided pull in the bag. The annular coupling member of the ring coupling is adapted to co-operate with an ostomy rod adapted to be placed under a bowel loop in case of transversal loop ostomy. For this purpose the ostomy rod has bevelled end faces to form oblique faces converging towards the under side of the rod, the oblique faces cooperating with a radially inwardly situated frusto-conical surface on the annular coupling member connected to the bandage. This enables positioning and change of the bandage without removing the ostomy rod from under the bowel loop.
