Abstract

The present invention relates to an apparatus for the removal and containment of human waste products from the effected area of incontinent patients. The apparatus and process encapsulates the areas of the body where urine and fecal matter are excreted. In particular, the present invention is directed to an apparatus for the containment and removal of human waste products, comprising: a receptacle; a vacuum connection to apply force for attaching the receptacle to the patient; and a vacuum dispersion membrane to provide mechanical support to the skin so as to minimize tensile force applied to the skin.

Claims

1. An apparatus comprising:

a flange surrounding a stoma of a patient, the flange having a first surface and an exterior surface, wherein the first surface is coupled with skin of the patient around the stoma;

a vacuum connection extending from the exterior surface to the first surface of the flange; and

a vacuum dispersion membrane disposed, at least in part, between the vacuum connection and the skin of the patient around the stoma,

wherein the vacuum connection is adapted to apply vacuum between at least a portion of the first surface of the flange and the skin of the patient around the stoma through the vacuum dispersion membrane, such that the stoma is not exposed to the vacuum;

a collection device, the collection device being coupled with the flange and at least partially enclosing the stoma; and

an inlet extending from the exterior surface to an interior surface of the flange for introducing a flushing fluid to an interior of the collection device, the interior surface being at least partially enclosed by the collection device.

2. The apparatus of claim 1, wherein the collection device is an ostomy bag.

3. The apparatus of claim 1, further comprising a vacuum control unit coupled with the vacuum connection for maintaining a vacuum level of the vacuum applied through the vacuum dispersion membrane within a predetermined range.

4. The apparatus of claim 3, wherein the vacuum control unit comprises at least one of a vacuum pump configured to apply the vacuum through the vacuum dispersion membrane, a check valve, or a vacuum control switch.

5. The apparatus of claim 1, wherein the vacuum dispersion membrane comprises at least one of polymer, textile, or synthetic material.

6. An apparatus comprising:

a flange surrounding a stoma of a patient, the flange having a first surface and an exterior surface, wherein the first surface is coupled with skin of the patient around the stoma;

a collection device coupled with the flange, the collection device at least partially enclosing the stoma;

a vacuum connection extending from the exterior surface to the first surface of the flange; and

a vacuum dispersion membrane disposed, at least in part, between the vacuum connection and the skin of the patient around the stoma,

wherein the vacuum connection is adapted to apply vacuum between at least a portion of the first surface of the flange and the skin of the patient around the stoma through the vacuum dispersion membrane, such that the stoma is not exposed to the vacuum; and

an inlet extending from the exterior surface to an interior surface of the flange for introducing a flushing fluid to an interior of the collection device, the interior surface being at least partially enclosed by the collection device.

7. The apparatus of claim 6, further comprising one or more nozzles in fluid communication with the inlet for dispersing the flushing fluid within the collection device.

8. The apparatus of claim 6, further comprising a vacuum control unit coupled with the vacuum connection for maintaining a vacuum level of the vacuum applied through the vacuum dispersion membrane within a predetermined range.

9. The apparatus of claim 8, wherein the vacuum control unit comprises at least one of a vacuum pump configured to apply the vacuum through the vacuum dispersion membrane, a check valve, or a vacuum control switch.

10. The apparatus of claim 6, further comprising a human waste detector for sensing presence of human waste in the collection device.

11. The apparatus of claim 6, further comprising an outlet in the collection device allowing at least one of fluids, gasses, or contaminants to exit the collection device.

12. A method comprising:

disposing a flange around a stoma of a patient, the flange having a first surface coupled with skin of the patient around the stoma, an exterior surface, a vacuum connection extending from the exterior surface to the first surface of the flange, and a vacuum dispersion membrane disposed, at least in part, between the vacuum connection and the skin of the patient around the stoma;

applying, via the vacuum connection, vacuum between at least a portion of the first surface of the flange and the skin of the patient around the stoma through the vacuum dispersion membrane, such that the stoma is not exposed to the vacuum; and

introducing a flushing fluid to an interior of a collection device, the collection device being coupled with the flange and at least partially enclosing the stoma.

13. The method of claim 12, further comprising dispersing the flushing fluid within the collection device.

14. The method of claim 12, further comprising mixing the flushing fluid with air.

15. The method of claim 12, further comprising draining at least one of fluids, gasses, or contaminants from the collection device.

16. The method of claim 12, further comprising detecting presence of human waste in a collection device, the collection device being coupled with the flange and at least partially enclosing the stoma.

17. The method of claim 12, further comprising maintaining a vacuum level of the vacuum applied through the vacuum dispersion membrane within a predetermined range.
