Ostomy system with repositionable pouch

An ostomy system comprising:

• a) an ostomy pouch including a pouch envelope formed of flexible plastic material defining a waste collection chamber for body waste that passes through a stoma, a waste inlet opening formed in said envelope for passage of waste material from said stoma to said collection chamber, a flexible annular adhesive pouch coupling member on said envelope at said waste inlet opening, said pouch coupling member having a resealable tape;
• b) a body-side mounting wafer having a stomal opening, said mounting wafer being engageable with the coupling member of said pouch, said mounting wafer having one side with an adhesive layer for securement to a body surface around a stoma, and an opposite side with a releasable film permanently secured to said wafer for engagement with the resealable tape of said pouch coupling member, such that said pouch can be secured to said wafer when the resealable tape of the pouch coupling member engages the releasable film of the wafer, said releasable film extending from an inner periphery surrounding said stomal opening to an outer periphery, said releasable film and said resealable tape permitting repeated removal of said pouch from said wafer and repeated resecurement and replacement of said pouch to said wafer;
• and
• c) support means coextensive and underlying said releasable film for preventing wrinkling of any part of said releasable film.
