example

[0062] Figure 4 A functional example of the ostomy appliance 1 of the present invention is shown in . Figure 4 is a plan view of the ostomy appliance 1 , wherein the part of the ostomy appliance behind its front wall 6 (when viewed in the viewing direction) is indicated with dashed lines.

[0063] The front wall 6 and the rear wall (not shown) are made of substantially inelastic flexible plastic material, about 75 μm thick, such as polyurethane, welded together so as to define a welded inner boundary 18 . The width of the internal collection area of ​​the ostomy appliance 1 (measured from the welded internal border 20, denoted by reference K) is 146 mm. The length (denoted by reference L) is 182 mm. The welded inner boundary 18 is substantially elliptical in shape. The diameter of the filter opening 9 (indicated by the reference sign M) is 5.5 mm, and the deodorizing filter 10 is located on the outer surface 8 of the front wall 6 completely covering the filter opening 9 ....

Abstract

An ostomy appliance (1) of the kind comprising a collecting bag for waste material, at least one opening (5) through which waste material may enter the collecting bag, at least one filter (10) allowing gas to exit the collecting bag and at least one pressure sensitive gas permeable barrier-filter (11) positioned between the at least one opening and the at least one filter, where the barrier-filter in its closed state blocks the passage of semi-solid waste and in its open state maintains an open passage for semi solid waste, where an increase in pressure inside the collecting bag passes a predefined first gas pressure limit triggering the transition of the barrier-filter from its closed state to its open state.

Description

technical field [0001] The invention relates to an ostomy appliance with a collection bag, wherein the collection bag has an opening for collecting waste material, a deodorizing gas filter and a pressure sensitive gas permeable barrier between the opening and the deodorizing gas filter A filter, wherein the barrier filter, when closed, prevents clogging of the deodorizing filter by semi-solid waste. Background technique [0002] One problem with using an ostomy appliance is that the ostomy appliance not only collects solid and / or liquid waste material from the user's bowel, but also collects expelled flatus gas. The volume of flatulence is significantly greater than the volume of other waste material, which can cause the ostomy appliance to swell and become flat because the flatulence cannot escape from the ostomy appliance. When the ostomy appliance is inflated to its maximum capacity (since flatulence can only escape from the intestine through the stoma and ostomy applian...
