IRIS DIAPHRAGM SEAL FOR AN OSTOMY BAG
First Claim
1. A sealing wafer for use in an ostomy appliance, comprisingan attachment platform having a distal surface capable of being attached to an ostomy bag, a proximal surface facing towards the user during use, and an opening having an inner boundary defining a stoma receiving opening,a fixed base member attached to the attachment platform,a rotating member arranged to rotate relative to the fixed base member,a sealing member coupled between the fixed base member and the rotating member for providing a seal around a stoma and defining a stoma sealing orifice,wherein a rotation of the rotating member relative to the base member causes an increased or a decreased tension to be applied to the sealing member so that the diametrical dimensions of the stoma sealing orifice change from a first diameter to a second diameter.

Abstract
A sealing wafer for use in an ostomy appliance is provided. The sealing wafer has an attachment platform with a distal surface capable of being attached to an ostomy bag, a proximal surface facing towards the user during use, and an opening having an inner boundary defining a stoma receiving opening. The sealing wafer further includes a fixed base member attached to the attachment platform and a rotating member arranged to rotate relative to the fixed base member. A sealing member is coupled between the fixed base member and the rotating member for providing a seal around a stoma and defining a stoma sealing orifice. When the rotating member is rotated relative to the base member, this rotation causes an increased or a decreased tension to be applied to the sealing member so that the diametrical dimensions of the stoma sealing orifice change from a first diameter to a second diameter. Thus a mechanical sealing member that can be used with one-piece ostomy appliances as well as with two-piece ostomy appliances is provided.
