Abstract

The ostomy bag comprises a receptacle pouch containing an inlet aperture and means for providing communication between the pouch interior and the ostomy orifice on the surface of the wearer'"'"''"'"'s body. This means comprises (a) a thin, flexible, essentially planar member containing a conduit which provides communication between the pouch inlet aperture and the ostomy orifice; (b) an upwardly projecting rim surrounding the conduit, over which the pouch inlet aperture is fitted; (c) a continuous groove in one surface of the planar member which surrounds the rim and in which the receptacle pouch is mounted, and (d) a recess in the surface of the planar member opposed to the grooved surface, this recess surrounding the conduit and adapted to receive a gasket or suitable means for sealing the ostomy bag to the body. The planar member is provided with means for affixing it to the body by use of a belt. The ostomy bag contains a gas permeable section in the pouch wall to permit release of intestinal gas from the interior to the exterior of the pouch. The pouch also contains a deodorizing packet affixed to the inner pouch wall. This packet comprises an inner sealed envelope containing a volatile deodorizing composition and an outer sealed envelope which contains the inner sealed envelope. The inner envelope is ruptured to discharge its contents into the inner space between the two envelopes. The outer envelope has microbial barrier properties and is permeable to the vapors emanating from the deodorizing composition. These deodorizing vapors pass through the outer envelope and into the environment surrounding the outer envelope.

Claims

2. a rim projecting upwardly from said outer surface and surrounding said conduit, said inlet aperture of said receptacle pouch fitting over said rim;

3. The ostomy bag of claim 2 wherein said conduit is of a circular configuration and wherein said rim, groove, and recess are of an annular configuration.

4. a recess in said inner surface surrounding said conduit and adapted to receive gasket sealing means therein, and

5. The ostomy bag of claim 4 wherein said gasket means is an O-ring fabricated from karaya gum.

6. The ostomy bag of claim 4 wherein said gasket means is an O-ring fabricated from a polyurethane sponge which is impregnated with karaya gum.

7. The ostomy bag of claim 4 wherein the inner surface of said planar member contains a centrally located annular taper surrounding said conduit, said taper rising upwardly from said inner surface and terminating upon reaching said annular recess.

8. The ostomy bag of claim 1 wherein said pouch contains therein a portion which is gas permeable and liquid impermeable, said portion providing communication between the interior and exterior of the pouch to provide for automatic release of gas to the exterior of the pouch.

9. The ostomy bag of claim 1 wherein said bag has affixed to the inner surface of said pouch a deodorizing packet comprising:

10. The ostomy bag of claim 9 wherein the outer envelope of the deodorizing packet is fabricated from a material also having microbial barrier properties.

11. The ostomy bag of claim 10 wherein said composition comprises a gel adapted for introducing into air a uniform quality vapor mixture, said gel comprising from about 96 to 99 percent of an aqueous medium, said aqueous medium containing from about 1 to 10 percent Of a plurality of volatile deodorizing agents which are compatible and uniformly dispersible in water, and which normally volatilize at different rates at room temperature, and from about 1 to 4 percent of an aqueous gelling agent, the amount of gelling agent present in proportion to the aqueous medium being such that the gel is firm and substantially devoid of syneresis.

12. The ostomy bag of claim 1 further including an opening in the bottom of said pouch, and means for opening and closing said opening.

13. An ostomy bag comprising:

14. The ostomy bag of claim 13 wherein the outer envelope of the deodorizing packet is fabricated from a material also having microbial barrier properties.

15. The ostomy bag of claim 13 wherein said means for providing communication between the interior of the pouch and the ostomy orifice comprises an essentially planar flexible member having an inner and outer surface said inner surface being adjacent the body surface in proximity to the ostomy orifice, said planar member containing:

16. The ostomy bag of claim 15 wherein said composition comprises a gel adapted for introducing into air a uniform quality vapor mixture, said gel comprising from about 96 to 99 percent of an aqueous medium, said aqueous medium containing from about 1 to 10 percent of a plurality of volatile deodorizing agents which are compatible and uniformly dispersible in water, and which normally volatilize at different rates at room temperature, and from about 1 to 4 percent of an aqueous gelling agent, the amount of gelling agent present in proportion to the aqueous medium being such that the gel is firm and substantially devoid of syneresis.

17. The ostomy bag of claim 15 wherein said inner envelope is fabricated from a laminate, said laminate comprising an outer layer of pouch paper, a first inner layer of polyethylene, a second inner layer of aluminum foil, and a third innermost layer of polyethylene.

18. The ostomy bag of claim 17 wherein said outer envelope is fabricated from a polyvinyl chloride film.

19. The ostomy bag of claim 18 wherein the liquid medium is an aqueous-alcoholic medium.

20. The ostomy bag of claim 19 wherein the amount of volatile deodorizing agents ranges from about 0.1 to about 0.25 percent.

21. The ostomy bag of claiM 16 further including an opening in the bottom of said pouch, and means for opening and closing said opening.

22. The ostomy bag of claim 16 further including gasket means disposed in said recess, said gasket means being non-irritating to skin.

23. The ostomy bag of claim 22 wherein said gasket means is an O-ring fabricated from karaya gum.

24. The ostomy bag of claim 20 wherein said conduit is of circular configuration and wherein the inner surface of said planar member contains a centrally located annular taper surrounding said conduit, said taper rising upwardly from said inner surface and terminating upon reaching said annular recess.
