Abstract

A device for firmly attaching human-waste-collection bags to the abdomen by using suction rings instead of adhesives. This device comprises of a cap (10) with suction rings, a round plastic sheet (11), a plastic bag (15), and a belt holder(14). A round body (12) of rigid material is used to sandwich the plastic sheet and bag by using the cap (10) at its front end. This device also has a belt holder (14) with a center hole (28) that fits on the rear ring surface (26) of the body (12). This belt holder is equipped with a regular elastic belt for pressing the overall devise firmly against the abdomen.

Claims

1. A human waste collection device for attaching to an abdomen, comprising:

an annular cap adapted to be pressed around a stoma in said abdomen, wherein said annular cap is comprised of an outer ring and an inner ring on an inner side of said annular cap, and a back plate connected between said outer ring and said inner ring on an outer side of said annular cap;

an annular cavity defined between said outer ring and said inner ring of said annular cap;

an annular round body comprised of a higher density plastic material than said annular cap, wherein said round body is positioned against said back plate of said annular cap on said outer side of said annular cap and is generally coextensive therewith;

a belt holder attached to said round body and adapted to be strapped around a person; and

a bag with an open end attached to a center hole of said round body for collecting human waste ejected from said stoma.

2. A human waste collection device for attaching to an abdomen, comprising:

an annular cap adapted to be pressed around a stoma in said abdomen, said annular cap is comprised of an outer ring and an inner ring on an inner side of said annular cap, and a back plate connected between said outer ring and said inner ring on an outer side of said annular cap;

a continuous annular cavity defined between said outer ring and said inner ring of said annular cap, said continuous cavity comprising a continuous annular suction ring for drawing skin into said cavity and preventing slippage;

an annular round body made of a higher density plastic material than said annular cap, said round body is positioned against said outer side of said annular cap and is generally coextensive therewith;

a belt holder attached to said round body and adapted to be strapped around a person;

a bag with an opening attached to a center hole of said round body for collecting human waste ejected from said stoma; and

a disposable flexible sheet detachably clamped between said annular cap and said annular round body, said flexible sheet including a hole substantially smaller than a center hole on said annular cap but large enough to encircle said stoma, said flexible sheet is adapted to isolate and protect said skin within said center hole on said annular cap from said human waste collected in said bag.

3. A human waste collection device for attaching to an abdomen, comprising:

an annular cap made of a and adapted to be pressed around a stoma in said abdomen, said annular cap is comprised of an outer ring and an inner ring on an inner side of said annular cap, a back plate connected between said outer ring and said inner ring on an outer side of said annular cap, and a snap-on ring around a circumference of said annular cap on said outer side;

a continuous annular cavity defined between said outer ring and said inner ring of said annular cap, said continuous cavity comprising a continuous annular suction ring for drawing skin into said cavity and preventing slippage;

an annular round body made of a higher density plastic material than said annular cap, said round body is positioned against said outer side of said annular cap and is generally coextensive therewith, said round body is detachably secured within said snap-on ring;

a belt holder attached to said round body and adapted to be strapped around a person;

a disposable bag attached to said annular round body for collecting human waste ejected from said stoma, said bag having an open end inserted through a center hole of said annular round body from an outer side of said annular round body, and detachably clamped between said annular cap and said annular round body;

a disposable flexible sheet detachably clamped between said annular cap and said annular round body inward of said bag, said flexible sheet including a round hole substantially smaller than a center hole on said annular cap but large enough to closely encircle said stoma, said plastic sheet is adapted to isolate and protect said skin within said center hole on said annular cap from said human waste collected in said bag; and

wrinkles on said bag and said flexible sheet between said annular cap and said annular round body enabling any gas in said bag to gradually and inconspicuously leak out and thus eliminating the need for sudden venting.

4. The human waste collection device of claim 3, further including an elastic ring squeezed between an outer rim of said annular round body and an inner rim of said snap-on ring to generally seal said bag and said plastic sheet against said snap-on ring.
