Abstract
An ostomy appliance having a body side member with an adhesive wafer or pad for securing the appliance to the user's skin, the wafer or pad having a hole for receiving a stoma, and a separately exchangeable collecting bag secured to the body side ostomy member for receiving secretions from the ostomy. The body side member includes a first flange connected thereto via a first connecting section and the collecting bag includes a second substantially annular flange which is connected to the collecting bag via a substantially annular second connecting section. The annular second flange is radially divided into an inner portion and an outer portion by at least one opening therethrough in an essentially circular zone corresponding to or larger than the outer radius of the first connecting section which reduces the risk of leakage and also reduces the necessary cleaning when substituting the collecting bag.
