Abstract

A urine collection device comprises a primary collection element shaped to surround a stoma formed in a person's abdomen, an outlet opening in the primary collection element, a drain tube connected to the outlet opening and extending distally from the primary collection element, an anti-backflow device positioned at the outlet opening of the primary collection element or within the primary collection element, the anti-backflow device restricting urine from backflowing from the drain tube into the primary collection element, and a secondary collection element connected to the distal end of the drain tube to collect the urine draining from the drain tube, wherein the secondary collection element is configured for coupling to the person at a location spaced apart from the primary collection element.

Claims (30)

1. A urine collection device for a person, comprising:

a primary collection element shaped to surround a stoma formed in the person's abdomen;

an outlet opening in the primary collection element via which urine received in the primary collection element through the stoma exits the primary collection element;

a drain tube connected to the outlet opening in the primary collection element and extending distally from the primary collection element, the drain tube draining urine from the primary collection element;

an anti-backflow device positioned at the outlet opening of the primary collection element or within the primary collection element, the anti-backflow device restricting urine from backflowing from the drain tube into the primary collection element; and

a secondary collection element connected to the distal end of the drain tube to collect the urine draining from the drain tube, wherein the secondary collection element is configured for coupling to the person at a location spaced apart from the primary collection element.

2. The urine collection device of claim 1 , wherein the secondary collection element is configured for coupling to the person below a beltline of the person.

3. The urine collection device of claim 1 , wherein the outlet opening in the primary collection element comprises a protruding spout.

4. The urine collection device of claim 1 , wherein the anti-backflow device is positioned in the primary collection element.

5. The urine collection device of claim 1 , wherein the anti-backflow device is positioned in the outlet opening of the primary collection element.

6. The urine collection device of claim 1 , wherein the anti-backflow device is a barbed check valve installed in the primary collection element with a barb fitting protruding through the outlet opening and connected to the drain tube.

7. The urine collection device of claim 1 , wherein the anti-backflow device comprises a Luer fitting.

8. The urine collection device of claim 1 , wherein the anti-backflow device comprises a duckbill-type member formed of a flexible material.

9. The urine collection device of claim 1 , wherein the primary collection element is configured to be adhesively coupled to the person's skin.

10. The urine collection device of claim 1 , wherein the secondary collection element is shaped to be suspended from a belt worn by the person, the belt being fitted for wearing adjacent the beltline.

11. A urine collection device for a person, comprising:

a primary collection element shaped to surround a stoma formed in the person's abdomen, the primary collection element having a base, a wall extending from the base and a primary collection volume defined by at least the base and the wall, further comprising a flange extending outwardly from the base and configured for adhesive attachment to the person's skin, and wherein the primary collection element is configured to receive urine from the body opening into the primary collection volume and convey the urine out of the primary collection volume in a first flow direction through an outlet opening in the wall;

an anti-backflow device positioned at the outlet opening in the wall or within the primary collection element;

a drain tube connected to the outlet opening in the primary collection element and extending distally from the primary collection element, the drain tube having a working length that extends at least as long as a distance from the body opening in the person's abdomen to a desired secondary collection element location below the person's beltline; and

a secondary collection element connected to the distal end of the drain tube to collect the urine draining from the drain tube, wherein the secondary collection member is configured for coupling to the person at the desired collection member location,

wherein the anti-backflow device is configured to restrict urine from backflowing into the primary collection volume in a second flow direction opposite the first flow direction and compromising the adhesive attachment between the base and the person's skin.

12. The urine collection device of claim 11 , wherein the anti-backflow device prevents urine from backflowing into the primary collection volume and increasing pressure within the primary collection element.

13. The urine collection device of claim 11 , wherein the anti-backflow device prevents urine from backflowing into the primary collection element and weakening the adhesive attachment between the flange and the person's skin.

14. The urine collection device of claim 11 , wherein the anti-backflow device comprises at least one of a barbed fitting or a Leuer fitting.

15. The urine collection device of claim 11 , wherein the anti-backflow device is positioned in the outlet opening in the wall.

16. The urine collection device of claim 11 , wherein the anti-backflow device is a check valve inserted through the wall in the primary collection element with a barb fitting protruding through the outlet opening and connected to the drain tube.

17. The urine collection device of claim 11 , wherein the anti-backflow device comprises a duckbill-type member formed of a flexible material.

18. The urine collection device of claim 11 , wherein the collection member is shaped to be suspended from a belt worn by the person, the belt being fitted for wearing adjacent the beltline.

19. The urine collection device of claim 11 , wherein the collection member is configured for being coupled to a leg of the person.

20. The urine collection device of claim 11 , wherein the drain tube is sized for wearing under a belt or clothing waist band without being compressed by the belt or clothing waist band.
