Abstract

Claims (37)

1. A fluid collection assembly, comprising:

a fluid impermeable barrier at least partially defining:

a waist opening;

two leg openings; and

at least one fluid outlet spaced from exterior edges of the fluid impermeable barrier and edges of the fluid impermeable barrier that at least partially define the two leg openings; and

at least one porous material generally conforming to at least a portion of the fluid impermeable barrier, the at least one porous material extending from or near a portion of the waist opening to or near an opposing portion of the waist opening, the at least one porous material including:

a fluid permeable membrane positioned to contact an individual, the fluid permeable membrane configured to receive and wick bodily fluids away from the individual; and

a fluid permeable support configured to have the bodily fluids flow therein, the fluid permeable support abuts substantially all of an interior surface of the fluid impermeable barrier that is not immediately adjacent to the at least one fluid outlet.

2. The fluid collection assembly of claim 1 , wherein the at least one fluid outlet is configured to be located at or near a gravimetric low point of the fluid impermeable barrier when an individual wearing the fluid collection assembly is at least one of standing, sitting, or lying down.

3. The fluid collection assembly of claim 2 , wherein the at least one fluid outlet includes a fluid outlet at or near a portion of the fluid impermeable barrier adjacent to a perineum or genitalia of the individual.

4. The fluid collection assembly of claim 2 , wherein the at least one fluid outlet includes a fluid outlet at or near a portion of the fluid impermeable barrier adjacent to at least one of a perineum or an anus of the individual.

5. The fluid collection assembly of claim 2 , wherein the at least one fluid outlet includes a fluid outlet that is between the waist opening and an anus of the individual.

6. The fluid collection assembly of claim 1 , further comprising at least one conduit in fluid communication with the at least one fluid outlet.

7. The fluid collection assembly of claim 1 , further comprising at least one fluid reservoir proximate to the at least one fluid outlet and between the fluid impermeable barrier and at least one porous material, wherein the at least one fluid reservoir is empty space.

8. The fluid collection assembly of claim 7 , wherein the fluid impermeable barrier includes a bulge that directly and partially defines the at least one fluid reservoir.

9. The fluid collection assembly of claim 7 , wherein the at least one porous material includes at least one concave surface directly defining a cutout, the at least one fluid reservoir is partially defined by the cutout.

10. The fluid collection assembly of claim 1 , wherein the fluid collection assembly does not include an adsorbent or absorbent material.

11. The fluid collection assembly of claim 1 , wherein the fluid collection assembly is configured for single use.

12. The fluid collection assembly of claim 1 , wherein the at least one fluid outlet includes a plurality of fluid outlets and each of the plurality of fluid outlets are spaced from the exterior edges of the fluid impermeable barrier and the edges of the fluid impermeable barrier that at least partially define the two leg openings.

13. The fluid collection assembly of claim 12 , further comprising a plurality of conduits attached to each of the plurality of fluid outlets, the plurality of tubes distinct and separate from the plurality of fluid outlets.

14. The fluid collection assembly of claim 1 , wherein the at least one porous material includes at least one of fabric, felt, gauze, a plurality of fibers, or an open cell foam.

15. The fluid collection assembly of claim 1 , wherein the fluid permeable support includes at least one of a porous polymer, an open cell foam, cotton, wool, silk, fabric, felt, or gauze.

16. The fluid collection assembly of claim 9 , wherein the fluid permeable support defines all of the at least one concave surface.

17. The fluid collection assembly of claim 1 , further comprising at least one fluid reservoir proximate to the at least one fluid outlet, the at least one fluid reservoir completely defined by the fluid impermeable barrier, the fluid permeable support, and the conduit, wherein the at least one fluid reservoir is empty space.

18. The fluid collection assembly of claim 1 , further comprising at least one fluid reservoir proximate to the at least one fluid outlet, the fluid permeable support positioned between the fluid permeable membrane and the at least one fluid reservoir spaced and spacing the fluid permeable membrane from the at least one fluid reservoir.

19. The fluid collection assembly of claim 1 , wherein the fluid permeable support abuts substantially all of an interior surface of the fluid impermeable barrier.

20. The fluid collection assembly of claim 1 , wherein the fluid permeable support extends continuously from or near a back portion of the waist opening to or near a front portion of the wait opening and from or near one of the two leg openings to or near the other one of the two leg openings, the back portion configured to be positioned adjacent to a back side of an individual and the front portion configured to be positioned adjacent to a front side of the individual.

21. The fluid collection assembly of claim 1 , wherein the fluid collection assembly is washable.

22. A fluid collection assembly, comprising:

a fluid impermeable barrier at least partially defining:

a waist opening;

two leg openings; and

at least one fluid outlet spaced from exterior edges of the fluid impermeable barrier and edges of the fluid impermeable barrier that at least partially define the two leg openings;

at least one porous material generally conforming to at least a portion of the fluid impermeable barrier, the at least one porous material extending from or near a portion of the waist opening to or near an opposing portion of the waist opening, the at least one porous material including:

a fluid permeable membrane positioned to contact an individual, the fluid permeable membrane configured to receive and wick bodily fluids away from the individual; and

a fluid permeable support configured to have the bodily fluids flow therein; and

at least one fluid reservoir proximate to the at least one fluid outlet, the at least one fluid reservoir completely defined by the fluid impermeable barrier, the fluid permeable support, and the conduit, wherein the at least one fluid reservoir is empty space.
