Abstract

An ostomy appliance having a ring portion and a sheath portion. The ring portion has a first side, a second side and an aperture substantially centered through the first side and the second side. The ring portion also includes a flange extending radially outward from the aperture. A collection pouch can be removably attached to the first side of the ring portion. A generally cylindrically shaped sheath portion has one end securely attached to the ring portion and a second end. The sheath includes a channel configured to accept the body passage through to the aperture on the ring portion. The sheath is made of a nonabsorbable, noncorrosive mesh material which allows the naturally occurring scaring process of the patient to fibrotically attach the sheath to the body passage, and thereby fixedly secure the ring portion to a substantially permanent location on the surface of the patient'"'"'s body from within the patient'"'"'s body.

Claims

1. A combination ring and collection pouch for an ostomy, said combination comprising:

a ring portion having a first side, a second side and an aperture substantially centered through said first side and said second side, said ring portion having a flange integrally formed on said ring portion which extends radially outward from said aperture to provide a support backing to said ring portion;

means for collecting waste matter from a body passage;

means for securing said collection means to said first side of said ring portion, said collection means communicating with said body passage through said aperture when said collection means is secured to said ring portion;

a flexible sheath being of a certain length and having one end securely attached to said second side of said ring portion and a second end, said sheath having a channel for accepting said body passage through to said aperture, said sheath conforming to said body passage throughout said length of said sheath, said sheath allowing naturally occurring scarring process of a patient'"'"'s body to fibrotically attach said sheath to said body passage and thereby fixedly secure said ring portion to a substantially permanent location on a surface of said patient'"'"'s body completely from within said patient'"'"'s body without adhesives; and

a nonabsorbable filament integral with and depending from said second side of said ring portion, said filament being independent of and extending through said first end of said sheath and terminating substantially at said second end of said sheath for securely attaching said ring portion to said sheath.

2. The combination as defined in claim 1 wherein said sheath is formed entirely of a nonabsorbable mesh material which is substantially porous.

3. The combination as defined in claim 2 wherein said mesh material has pores of between 600 and 750 microns in diameter.

4. The combination as defined in claim 1 wherein said filament is woven in and through said mesh sheath.

5. An ostomy appliance for the collection of bodily fluids from a stoma of a body passage of a patient, said ostomy appliance comprising:

a faceplate having a first side, a second side and a substantially centered aperture which extends through said first side and said second side, said faceplate having an integral flange which extends radially outward from said aperture to provide a resilient support backing structure for said faceplate;

said faceplate having means for releasably securing a collection pouch around said aperture;

a sheath formed of a mesh being of a predetermined length and having a first end and a second end, said first end being securely attached to said second side of said faceplate substantially alongside and around said aperture, said second end of said mesh sheath having a channel for accepting said body passage therethrough, said sheath and said channel generally conforming to said body passage throughout said predetermined length of said sheath; and

a filament being independent of said mesh sheath and attached at one end to said second side of said faceplate, said filament being interwoven in said mesh and extending substantially said predetermined length of said sheath, said filament providing a secure attachment of said faceplate to said sheath.

6. The ostomy appliance as defined in claim 5 wherein said mesh sheath has pores of between 600 and 750 microns in diameter.

7. The ostomy appliance as defined in claim 5 wherein said filament spirals in and through said mesh sheath for substantially the entire length of said sheath.
