Abstract

A drainable ostomy pouch has an outlet. Reinforcing members at the outlet are deformable by application of manual pressure at their ends to distend the outlet. The lateral edges of the reinforcing members may be offset, which encourages the reinforcing members to consistently bend away from each other. A peelable distributed mechanical engagement fastener secures the outlet in a folded condition. The fastener parts are hook-hook type plastic extrusions, and provide a snap-engagement. A security flap is foldable under the outlet when in its folded condition. The outlet is released in two stages.

Claims

1. A drainable ostomy poach for collecting human waste, the pouch comprising:

a) an outlet having opposing pouch walls and an opening there between;

b) first and second deformable reinforcing members each reinforcing member being attached to an opposing pouch wall near or at the outlet opening, the first reinforcing member having two opposite first lateral edges, the second reinforcing member having two opposite second lateral edges, cacti of the first lateral edges being proximate to a respective second lateral edge, the first and second reinforcing members being deformable by manual application of pressure to opposite lateral edges of the reinforcing members so as to controllably distend the outlet opening;

wherein a first lateral edge of the first reinforcing member is offset laterally with respect to a second lateral edge of the second reinforcing member;

c) the outlet being foldable from an extended condition to a stowed condition;

d) a fastener for use in securing the outlet in its stowed condition, the fastener being a peel able distributed mechanical engagement fastener including first and second fastener parts, the first and second fastener pails having the same fastener projections as each other that provide a snap engagement when pressed together, wherein the first fastener part is carried on a first exterior face of the pouch, and the second fastener part is carried on a second exterior face of the pouch opposite the first face;

e) an outlet fastener for directly securing the outlet in its stowed condition;

f) a security flap having two ends, a first end secured to an exterior face of the pouch, and a second end releasable securable to the pouch, the security flap being foldable around the outlet when the flap outlet is in its stowed condition; and

g) a flap fastener for directly securing the second end of the security flap in its folded condition around the stowed outlet so as to provide a protective sling tinder the outlet.

2. The drainable ostomy pouch according to claim 1, wherein at least one of the fastener parts is on a portion of the outlet for directly securing the outlet in its stowed condition.

3. The drainable pouch according to claim 1, wherein a third fastener part is on the security flap.

4. The drainable pouch according to claim 1, wherein when the outlet is in the stowed condition peripheral edges of the reinforcing members are inboard of a zone of cushioning material.
