Ostomy appliance

An ostomy appliance made of a plastic material and comprising:

• a pouch-holder having a relatively rigid end-piece;
• said end-piece being fixed about a stoma opening in the body of the user so that said end piece surrounds the stoma during use
• a flexible waste collecting ouch having a nose extending therefrom which is resiliently deformable and engageable within said end piece;
• a resiliently deformable clamping member connected with the pouch holder and acting by clamping action for immobilizing the pouch nose with respect to the end-piece by a mating shape effect;
• and
• a control mechanism for actuating said clamping member such that said clamping member provides a sealed mechanical connection of said pouch nose within said end-piece upon actuation of said control mechanism.

Pouch for collecting body waste and/or fluids, particularly for enterostomy or urostomy, entering into the construction of an appliance comprising:

• a pouch-holder with an end-piece for being fixed about a stoma opening in the body of a user so that said end-piece surrounds the stoma during use,
• a waste material collecting pouch adapted to be releasably secured with the pouch-holder by an annular nose of the pouch and which is provided for engaging said end-piece,
• a control mechanism for the appliance connected to the pouch-holder,
• a deformable clamping member connected to the pouch-holder and which is separate from said control mechanism for cooperating directly and solely with the pouch nose, said clamping member including means for providing a sealed mechanical connection of said pouch nose with said end-piece in response to actuation of said mechanism wherein the pouch nose comprises a flexible resiliently deformable material and whose cross section mates with that of the clamping ember, on the one hand, and is paired with the end-piece of the pouch-holder, on the other hand, to provide the sealed connection between the pouch and the pouch-holder.
