Abstract
The invention relates to an ostomy pouch 10. The pouch 10 includes inner and outer walls 18b, 20b of flexible sheet material which sealed about a periphery. The walls 18b, 20b define a cavity for containing a stomal output and a drain 32 for draining stomal output from the cavity. An opaque comfort layer 18a, 20a is provided, at over an outer surface of the inner and/or outer walls 18b, 20b. The drain 32 is moveable between a deployed position for draining the stomal output from the cavity and a stowed position for storage of the drain 32, with at least part of the drain 32 overlying a portion of the comfort layer 18a, 20a in the stowed position. The drain 32 is substantially opaque on one side, and at least partly transparent on an opposing side.
Claims17
An ostomy pouch, comprising:
- inner and outer walls of flexible sheet material sealed about a periphery thereof to define:
- a cavity for containing a stomal output;
- and
- a deployable drain for draining stomal output from the cavity;
- a substantially opaque comfort layer provided, at least in part over an outer surface of the inner and/or outer walls of the flexible sheet material;
- and
- a fastener arrangement configured to retain the deployable drain in the stowed position, the fastener arrangement comprising a first fastener located on an outer surface of the comfort layer and a second fastener provided on the inner wall or outer wall of the ostomy pouch;
- wherein the deployable drain is moveable between a deployed position for draining the stomal output from the cavity and a stowed position for storage of the deployable drain, with at least part of the drain overlying a portion of the comfort layer in the stowed position;
- wherein at least a portion of the inner wall defining the deployable drain is opaque and at least a portion of the outer wall defining the deployable drain is at least partly transparent;
- wherein the first fastener comprises a flap which is secured to the comfort layer;
- wherein the flap is provided on the comfort layer overlying an outer wall of the pouch, away from the ostomate, in use, and extends across substantially the entire width of the ostomy pouch, out towards a sealed periphery of the ostomy pouch;
- wherein the flap is provided with a flange projecting downwards from the flap and positioned to overlie a portion of the deployable drain when in the stowed position, the flange being an outermost layer when the deployable drain is in the stowed position;
- and
- wherein the pouch comprises one or more curved edges, and the flap is similarly curved to correspond the shape and form of the curved edge(s) of the pouch.
