Embodiment Construction

[0049] Referring to the above drawings, the ostomy bag 1 according to one embodiment of the present invention includes an outer protective bag 3 and an inner bag 5 for excrement collection. The waste collection inner bag 5 is made of laminated material. The innermost layer 7 of the excrement collection inner bag 5 is an ethylene-vinyl alcohol copolymer (EVA) film, such as DEV-07-04A film produced by Exopack Company. The innermost layer 7 is waterproof, strong enough to contain bodily waste stored therein and to provide an odor barrier. The innermost layer 7 of EVA is only a small part of the overall thickness of the waste collection inner bag 5 , making it inconspicuous relative to the ostomy bag 1 as a whole. This allows the ostomy bag 1 to be flushed away.

[0050] The innermost layer 7 protects the dissolvable outer layer 9 of the excrement collection inner bag 5 from being polluted by the contents of the ostomy bag. The outer layer 9 of the waste collection inner bag 5 ...

Abstract

An ostomy bag (1) for receiving bodily waste comprising; an outer protective pouch (3) comprising a laminated material with an outer layer of water-impermeable material (15) and an inner layer of water-soluble material (13); an inner waste-collecting pouch (5) enclosed within the outer protective pouch (3) comprising a laminated material with an outer layer of water-soluble material (9) and an inner layer of water-impermeable material (7), and means (23) defining an orifice (19) to enable bodily waste to enter the inner pouch (5); wherein the outer protective pouch (3) is removeably sealed and both the outer protective pouch (3) and inner waste-collecting pouch (5) are of a structure which is weakened upon immersion in a toilet bowl to both become less buoyant such that the bag (1) can be flushed away.

Description

technical field [0001] The present invention relates to ostomy bags, and more particularly to ostomy bags that can be hygienically flushed down a toilet. Background technique [0002] Ostomy bags for receiving bodily discharges are well known. A major problem with existing ostomy bags is that it is difficult to dispose of used ostomy bags in a convenient and hygienic manner. For example, some existing ostomy bags require the user to cut the edge of the ostomy bag to sink the contents of the ostomy bag into the toilet, and the soiled ostomy bag needs to be disposed of separately. Soiled ostomy bags need to be wrapped up and placed in the trash or burned. Handling the ostomy bag in this manner is unhygienic, uncomfortable and inconvenient for the user. [0003] Various proposals have been made for ostomy bags that can be flushed down the toilet. However, there are still obvious deficiencies in the products that have been developed today. Ostomy bags are difficult to wash ...
