Abstract

Claims (45)

1 . A fluid collection device, comprising:

a fluid impermeable barrier at least partially defining a chamber and an opening, the fluid impermeable barrier including a first end region and a second end region;

a fluid permeable body positioned at least partially within the chamber to extend across at least a portion of the opening and configured to allow fluid to move away from the opening, the fluid permeable body including a protruding portion protruding out of the opening and that is sized and shaped to fit between labia of a wearer; and

a conduit disposed within the chamber for removing fluids therefrom.

2 . The fluid collection device of claim 1 wherein the fluid permeable body includes a fluid permeable support and a fluid permeable membrane disposed over at least a portion of the fluid permeable support.

3 . The fluid collection device of claim 1 , further comprising a means for retaining the protruding portion between the labia of the wearer.

4 . The fluid collection device of claim 3 wherein at least a portion of one or more of the fluid impermeable barrier and the fluid permeable body are shaped to accommodate the labia therein and the means for retaining the protruding portion between the labia of the wearer includes the at least a portion of one or more of the fluid impermeable barrier and the fluid permeable body.

5 . The fluid collection device of claim 3 wherein:

the means for retaining the protruding portion between the labia of the wearer includes adhesive flaps disposed on the fluid impermeable barrier; and

the adhesive flaps include an adhesive on a wearer-facing side thereof.

6 . The fluid collection device of claim 5 wherein the adhesive flaps or straps are sized and positioned on the fluid impermeable barrier to secure to the legs, pelvis, or buttocks of the wearer.

7 . The fluid collection device of claim 3 wherein:

the means for retaining the protruding portion between the labia of the wearer includes an additional protrusion extending from the first end region of the fluid impermeable barrier on a wearer-facing side thereof; and

the additional protrusion is sized and shaped to fit between buttocks of the wearer.

8 . The fluid collection device of claim 3 wherein the fluid impermeable barrier is shaped as a trough and the opening is disposed at a wearer-facing side of the trough, the fluid collection device includes a plurality of spring members extending longitudinally along the opening, the plurality of spring members being configured to provide an outward bias on the opening, and the fluid permeable body protrudes from the opening.

9 . The fluid collection device of claim 3 wherein the fluid impermeable barrier includes extends over a portion of the protruding portion.

10 . The fluid collection device of claim 9 wherein the fluid impermeable barrier has a substantially flat arcuate shape on a wearer-facing side thereof and a narrow portion sized and shaped to provide a grip section for gripping or pinching in a hand.

11 . The fluid collection device of claim 9 , further comprising a foldable body configured to attach to the fluid impermeable barrier and the wearer and bias the protruding portion toward the wearer.

12 . The fluid collection device of claim 11 wherein the foldable body includes:

a first fold along a center thereof; and

a cutout portion defined between cuts perpendicular to the first fold; and

a second fold in the in the cutout portion, the second fold being oriented to fold in a direction opposite to the first fold.

13 . The fluid collection device of claim 12 wherein at least a portion of the fluid impermeable barrier is disposed between the first fold and the second fold.

14 . The fluid collection device of claim 12 wherein:

the fluid impermeable barrier includes a flange longitudinally extending along a back side thereof; and

the second fold of the foldable body is disposed beneath the flange.

15 . The fluid collection device of claim 3 wherein:

the fluid impermeable barrier includes a substantially domed shape on a wearer-facing side thereof and the opening is defined at a base edge of the domed shape;

the fluid permeable body is attached to the chamber of the fluid impermeable barrier at the first end region and the second end region; and

the fluid permeable body is substantially cylindrical and curved to bend outwardly from the opening.

16 . The fluid collection device of claim 15 wherein the fluid impermeable barrier includes a narrow portion sized and shaped to provide a grip section for gripping or pinching in a hand.

17 . A fluid collection system, the system comprising:

a fluid collection device according to claim 1 ;

a fluid storage container fluidly connected to the fluid collection device via the conduit, the fluid storage container being configured to store fluids therein; and

a vacuum source fluidly connected to the fluid storage container, the vacuum source being configured to provide vacuum force into the chamber via the fluid storage container and the conduit.

18 . The fluid collection system of claim 17 wherein the vacuum source includes one or more of a vacuum pump, a wall-mounted vacuum line, or a hand pump.

19 . A method to collect fluid, the method comprising:

positioning a fluid collection device adjacent to a urethra of a wearer, the fluid collection device including,

a fluid impermeable barrier at least partially defining a chamber and an opening, the fluid impermeable barrier including a first end region and a second end region,

a fluid permeable body positioned at least partially within the chamber to extend across at least a portion of the opening and configured to allow fluid to move away from the opening, the fluid permeable body including a protruding portion protruding out of the opening and that is sized and shaped to fit between labia of a wearer, and

a conduit disposed within the chamber for removing fluids therefrom,

wherein the positioning is effective to position the protruding portion between the labia of the wearer;

receiving fluid from the urethra into the fluid collection device; and

removing the fluid from the fluid collection device via the conduit.

20 . The method of claim 19 , further comprising engaging the means for retaining the protruding portion between the labia of the wearer.
