Abstract

The suspended urinary external drainage system includes a liquid barrier with a periphery attached to a collector, with a tubular cross section, that encircles the barrier. A plurality of capillary tubes pass through a wall of the collector. Each of the plurality of capillary tubes has a capillary inlet adjacent to the liquid barrier and a capillary discharge inside the collector. A soft lining covers the capillary tubes. Discharge tubes connected to the collector carry urine to a holding bag.

Claims

1. A diaper comprising:

a liquid barrier having a front area, a crotch area, a back area and a periphery;

a lining, that permits the passage of liquid, secured to the periphery of the liquid barrier;

a first plurality of capillary tubes, each of which has a first capillary tube inlet positioned between the front area of the liquid barrier and the lining and a first capillary tube discharge inside a collector;

a second plurality of capillary tubes, each of which has a second capillary tube inlet positioned between the crotch area and the liquid barrier and the lining and a second capillary tube discharge inside the collector;

and a seal between a collector wall of the collector and each of the plurality of first and second capillary tubes.

2. A diaper, as set forth in claim 1, wherein the first capillary tube discharge, of each of the plurality of capillary tubes, is spaced from a collector wall inside surface;

and wherein the second capillary tube discharge, of each of the plurality of second capillary tubes is spaced from the collector wall inside surface.

3. A diaper, as set forth in claim 1, wherein the collector is secured to said barrier.

4. A diaper, as set forth in claim 1, wherein the collector has a plurality of collector discharge openings.

5. A diaper, as set forth in claim 4, wherein each of the plurality of collector discharge openings is connected to a liquid holding bag by a discharge tube.

6. A suspended urinary external drainage system comprising:

a flexible outer liquid barrier material having a back portion, a front portion, a crotch portion that is integral with the back portion and the front portion, and an outer edge;

a collector tube having a collector tube wall secured to an outer edge of the flexible outer liquid barrier and extending along a left side of the back portion, a left side of the crotch portion, a left side of the front portion, a front top side of the front portion, a right side of the front portion, a right side of the crotch portion and a right side of the back portion;

a plurality of capillary tubes that pass through the collector tube wall and wherein each capillary tube in a first group of the plurality of capillary tubes has a first group inlet end positioned adjacent to a front portion inside surface of the flexible outer liquid barrier material, each capillary tube in a second group of the plurality of capillary tubes has a second group inlet end positioned adjacent to a crotch portion inside surface and the plurality of capillary tubes each have a discharge end inside the collector tube;

a lining having a lining edge that is secured to the collector tube wall and wherein the lining permits the passage of liquid;

a plurality of liquid discharge openings through the collector tube wall; and

discharge tubes connected to the liquid discharge openings.

7. A suspended urinary external drainage system as set forth in claim 6 wherein said collector tube is an endless ring that encircles the flexible outer liquid barrier material and wherein said collector tube extends along a rear topside of the back portion.

8. A suspended urinary external drainage system as set forth in claim 6 wherein the discharge end of each of the capillary tubes extends inward into said collector tube a distance past an inside surface of said collector tube.

9. A suspended urinary external drainage system as set forth in claim 6 wherein a seal is created between the wall of said collector tube and each of the plurality of capillary tubes.

10. A suspended urinary external drainage system as set forth in claim 9 wherein the discharge end of each of the plurality of capillary tubes is spaced from the seal between the wall of said collector tube and each of the plurality of capillary tubes.

11. A suspended urinary external drainage system as set forth in claim 6 wherein the lining is a soft non-absorbent material.

12. A method of collecting urine from an incontinent person comprising:

attaching a diaper with a liquid barrier and a lining to the incontinent person;

collecting urine that passes through the lining with a plurality of capillary tubes;

moving urine through the plurality of capillary tubes to a discharge end of each of the plurality of capillary tubes;

collecting urine discharged from the plurality of capillary tubes in a collector; and

transferring urine from the collector to a urine holder.
