Abstract

A system suitable for collecting and transporting urine away from the body of a person or animal may include an assembly having a fluid impermeable casing having a fluid reservoir at a first end, a fluid outlet at a second end, and a longitudinally extending fluid impermeable layer coupled to the fluid reservoir and the fluid outlet and defining a longitudinally elongated opening between the reservoir and the outlet. The assembly can further include a fluid permeable support disposed within the casing with a portion extending across the elongated opening, and a fluid permeable membrane disposed on the support and covering at least the portion of the support that extends across the elongated opening, so that the membrane is supported on the support and disposed across the elongated opening. The assembly can further include a tube having a first end disposed in the reservoir and a second, fluid discharge end.

Claims (52)

1. A fluid collection device, comprising:

a fluid impermeable layer having a proximal end region and a distal end region, the fluid impermeable layer at least partially defining an interior volume of the fluid collection device and at least partially forming a first region of the fluid collection device;

a fluid permeable membrane having an outer surface positioned to contact skin of a user and form at least a portion of a second region of the fluid collection device, wherein the outer surface of the fluid permeable membrane extends convexly outward away from at least a portion of the fluid impermeable layer;

an outlet positioned at the proximal end region of the fluid impermeable layer and in fluid communication with the interior volume of the fluid collection device;

a sump positioned in the distal end region of the fluid impermeable layer, the sump being defined at least partially by the fluid impermeable layer;

an elongated tube having an intake end disposed in the interior volume at least proximate to the sump and in fluid communication with the outlet;

a permeable member disposed at least partially in the interior volume of the fluid collection device, wherein the permeable member and the fluid permeable membrane are at least partially concentric around the elongated tube.

2. The fluid collection device of claim 1 , wherein the fluid collection device is substantially cylindrical with the outer surface of the fluid permeable membrane extending outward away from at least the portion of the fluid impermeable layer.

3. The fluid collection device of claim 1 , wherein:

the fluid impermeable layer includes a first portion at least partially forming the first region of the fluid collection device and a second portion at least partially forming the second region of the fluid collection device opposite to the first region, the second portion of the fluid impermeable layer overlying the first portion of the fluid impermeable layer to define at least some of the interior volume therebetween; and

the fluid permeable membrane is exposed through the second portion of the fluid impermeable layer, with the second portion of the fluid impermeable layer and the outer surface of the fluid permeable membrane extending convexly outward away from the first portion of the fluid impermeable layer.

4. The fluid collection device of claim 1 , further comprising an elongated member configured to retain a nonlinear configuration after being adjusted to the nonlinear configuration to maintain the fluid collection device in the nonlinear configuration.

5. The fluid collection device of claim 4 , wherein the elongated member is proximate to the elongated tube.

6. The fluid collection device of claim 1 , wherein the outer surface of the fluid permeable membrane has a surface area that is smaller than an external surface area of the permeable member.

7. The fluid collection device of claim 6 , wherein at least a portion of the fluid permeable membrane is sealed to the fluid impermeable layer such that the fluid permeable membrane and the fluid impermeable layer together form a sheath sized to hold the permeable member therein.

8. The fluid collection device of claim 1 , wherein the fluid impermeable layer includes one or more extension portions.

9. The fluid collection device of claim 8 , wherein the one or more extension portions are shaped as an elongated tab that extends longitudinally on an outer periphery along the fluid collection device and between the second region and the first region of the fluid collection device.

10. The fluid collection device of claim 9 , wherein the one or more extension portions are heat sealed proximate to the outer periphery of the fluid collection device.

11. The fluid collection device of claim 1 , further comprising a stabilizer secured to the fluid collection device at least proximate to the outlet and having an adhesive configured to adhere to skin of the user.

12. The fluid collection device of claim 1 , wherein the intake end of the elongated tube is a beveled intake end.

13. The fluid collection device of claim 1 , wherein the fluid impermeable layer defines one or more vacuum relief openings.

14. A fluid collection device, comprising:

a fluid impermeable backing having a proximal end region and a distal end region, the fluid impermeable backing at least partially defining an interior volume of the fluid collection device and at least partially forming a first region of the fluid collection device;

a fluid permeable membrane at least partially covering the interior volume of the fluid collection device and having an outer surface positioned to contact skin of a user and form at least a portion of a second region of the fluid collection device, wherein the outer surface of the fluid permeable membrane extends convexly outward away from at least a portion of the fluid impermeable backing;

an outlet positioned at the proximal end region of the fluid impermeable backing and in fluid communication with the interior volume of the fluid collection device;

a sump positioned in the distal end region of the fluid impermeable backing distal to the outlet, the sump being defined at least partially by a portion of the fluid impermeable backing;

an elongated tube having an intake end disposed in the interior volume at least proximate to the sump and in fluid communication with the outlet;

a permeable member disposed at least partially in the interior volume of the fluid collection device, wherein the permeable member and the fluid permeable membrane are at least partially concentric around the elongated tube.

15. The fluid collection device of claim 14 , further comprising a spine disposed in the fluid collection device between the outer surface formed by the fluid permeable membrane and at least the portion of the fluid impermeable backing at least partially forming the first region of the fluid collection device, wherein the spine divides the interior volume of the fluid collection device into at least two channels.

16. The fluid collection device of claim 14 , further comprising a tunnel formed integrally with the fluid impermeable backing and extending longitudinally in the fluid collection device, the tunnel defining a chamber therein in fluid communication with the outlet and the interior volume of the fluid collection device.

17. The fluid collection device of claim 14 , further comprising:

wherein the fluid impermeable backing at least partially defines an opening at the distal end region distal to the outlet and proximate to the sump; and

a wall spaced from the fluid impermeable backing such that the wall and the fluid impermeable backing collectively define a channel extending longitudinally from the opening along the first region of the fluid collection device and in fluid communication with the outlet.

18. The fluid collection device of claim 14 , wherein the fluid impermeable backing includes one or more extension portions shaped as an elongated tab that extends longitudinally on an outer periphery along the fluid collection device and between the second region and the first region of the fluid collection device.

19. The fluid collection device of claim 14 , wherein the outer surface of the fluid permeable membrane has a surface area that is smaller than an external surface area of the additional permeable member.

20. The fluid collection device of claim 19 , wherein at least a portion of the fluid permeable membrane is sealed to the fluid impermeable backing such that the fluid permeable membrane and the fluid impermeable backing together form a sheath sized to hold the permeable member therein.

21. The fluid collection device of claim 14 , further comprising a stabilizer secured to the fluid collection device at least proximate to the outlet and having an adhesive configured to adhere to skin of the user.

22. The fluid collection device of claim 14 , wherein the intake end of the elongated tube includes a beveled intake end.
