Abstract

Examples relate to devices, systems, and methods for fluid collection such as urine. The urine collection device includes a fluid impermeable barrier and a fluid permeable body. The fluid impermeable barrier at least partially defines a chamber. The fluid impermeable barrier includes at least one elongated portion having a first width and distal to the aperture and a second portion having a second width greater than the first width. The second portion at least partially defines an opening in the fluid impermeable barrier, and the opening has a maximum lateral dimension greater than the first width of the elongated portion. The fluid permeable body is configured to wick fluid away from the opening into the at least one elongated portion.

First claim

What is claimed is:

1 . A urine collection device, comprising:
a fluid impermeable layer including a first end region having a first width and a second end region having a second width that is at least about 2 times greater than the first width of the first end region such that the fluid impermeable layer narrows between the second end region and the first end region; one or more fluid permeable layers secured to the fluid impermeable layer, at least one fluid permeable layer of the one or more fluid permeable layers positioned to be at least proximate to a urethra of a subject when the urine collection device is secured to the subject; and a conduit positioned between at least a portion of the one or more fluid permeable layers and the fluid impermeable layer, the conduit extending from an inlet at least proximate to the first end region of the fluid impermeable layer to the second end region of the fluid impermeable layer, wherein the conduit is configured to couple to a vacuum source effective to pull urine discharged into the urine collection device into the inlet and through the conduit for removal from the urine collection device.

2 . The urine collection device of claim 1 , wherein at least a portion of the at least one fluid permeable layer of the one or more fluid permeable layers positioned to be at least proximate to the urethra of the subject forms a substantially concave surface on the urine collection device.

3 . The urine collection device of claim 2 , wherein the at least a portion of the at least one fluid permeable layer of the one or more fluid permeable layers includes a wicking material forming the substantially concave surface positioned to be at least proximate to the urethra of the subject.

4 . The urine collection device of claim 1 , further comprising a reservoir of void space at the first end region of the fluid impermeable layer and configured to hold at least some of the urine discharged into the urine collection device, the inlet of the conduit being positioned at least proximate to the reservoir.

5 . The urine collection device of claim 4 , wherein the one or more fluid permeable layers include at least a wicking material configured to direct the urine towards the reservoir and the inlet of the conduit.

6 . The urine collection device of claim 1 , wherein the fluid impermeable layer defines an aperture at the second end region and the conduit extends through the aperture.

7 . The urine collection device of claim 1 , wherein the fluid impermeable layer includes a fluid impermeable film and at least one permeable layer of the one or more permeable layers includes a wicking material.

8 . The urine collection device of claim 7 , wherein the wicking material forms at least a portion of a front side of the urine collection device and the fluid impermeable film forms a rear side of the urine collection device.

9 . A urine collection device, comprising:
a first region of fluid impermeable material at a first end region of the urine collection device, the first end region having a first width and the first region of fluid impermeable material defining a reservoir of void space in the first end region of the urine collection device; a second region of fluid impermeable material at a second end region of the urine collection device and narrowing in width as the second region of fluid impermeable material extends to the first end region, the second end region having a second width that is at least about 2 times greater than the first end region; a fluid permeable material extending at least partially between the first end region and the second end region, at least some of the fluid permeable material positioned to be at least proximate to a urethra of a subject when the urine collection device is secured to the subject; and a conduit having an inlet positioned at least proximate to reservoir of void space in the first region of fluid impermeable material, the conduit extending from the inlet between at least some of the fluid permeable material and the second region of fluid impermeable material and to the second end region of the urine collection device, wherein the conduit is configured to couple to a vacuum source effective to pull urine collected in the reservoir into the inlet and through the conduit for removal from the urine collection device.

10 . The urine collection device of claim 9 , wherein the at least some of the fluid permeable material positioned to be at least proximate to the urethra of the subject forms a substantially concave surface on the urine collection device.

11 . The urine collection device of claim 10 , wherein the at least some of the at the fluid permeable material includes a wicking material forming the substantially concave surface positioned to be at least proximate to the urethra of the subject.

12 . The urine collection device of claim 9 , wherein the fluid permeable material includes at least a wicking material configured to direct the urine towards the reservoir and the inlet of the conduit.

13 . The urine collection device of claim 12 , wherein the second region of fluid impermeable material includes a fluid impermeable film.

14 . The urine collection device of claim 13 , wherein the wicking material forms at least a portion of a front side of the urine collection device and the fluid impermeable film forms of the second region of fluid impermeable material forms a rear side of the urine collection device.

15 . The urine collection device of claim 9 , wherein the fluid impermeable layer defines an aperture at the second end region and the conduit extends through the aperture.

16 . A urine collection device, comprising:
a fluid impermeable layer; a fluid permeable material secured to the fluid impermeable layer, at least some of the fluid permeable material positioned to be at least proximate to a urethra of a subject when the urine collection device is secured to the subject; a first member extending longitudinally between the fluid permeable material and the fluid impermeable layer; a second member extending longitudinally between the fluid permeable material and the impermeable layer; and a connector secured to the first member and the second member, the first member and the second member forming a V-shaped configuration in the urine collection device when secured to the connector; wherein at least one member of the first member or the second member is substantially tubular and in fluid communication with the connector and configured to transport urine from within the urine collection device when fluidly coupled to a vacuum source for removal from the urine collection device.

17 . The urine collection device of claim 16 , wherein the at least some of the fluid permeable material positioned to be at least proximate to the urethra of the subject forms a substantially concave surface on the urine collection device.

18 . The urine collection device of claim 17 , wherein the at least some of the at the fluid permeable material includes a wicking material forming the substantially concave surface positioned to be at least proximate to the urethra of the subject.

19 . The urine collection device of claim 16 , wherein the fluid impermeable layer includes a fluid impermeable film.

20 . The urine collection device of claim 19 , wherein the wicking material forms at least a portion of a front side of the urine collection device and the fluid impermeable film forms of the second region of fluid impermeable material forms a rear si
