Abstract

Examples relate to systems, devices, and methods for collecting fluid from wearer of the fluid collection device. The fluid collection devices include porous material having one or more raised portions to fit within the female anatomy near the urethra. A fluid collection system includes a fluid collection device operably coupled to a fluid storage container and vacuum source via one or more sections of conduit.

First claim

What is claimed is:

1 . A fluid collection device, comprising:
a fluid impermeable barrier having an outer surface and an inner surface, the inner surface at least partially defining a chamber, the fluid impermeable barrier also defining an opening extending therethrough, the opening configured to be positioned adjacent to a female urethra, the fluid impermeable barrier defining an aperture sized to receive a conduit; and a porous material at least partially disposed in the chamber, the porous material having a body and a raised portion extending longitudinally along the body and through the opening.

2 . The fluid collection device of claim 1 , wherein the raised portion includes a cusp extending away from the body.

3 . The fluid collection device of claim 1 , wherein the raised portion includes a lobe standing off of the body.

4 . The fluid collection device of claim 1 , wherein:
the body is substantially cylindrical; and the raised portion is convex and extends away from the body at least 5 mm.

5 . The fluid collection device of claim 1 , wherein the porous material includes:
a fluid permeable membrane disposed within the chamber and extending across the opening; and a fluid permeable support disposed within the chamber beneath the fluid permeable membrane, the fluid permeable support including the raised portion thereon.

6 . The fluid collection device of claim 1 , wherein the raised portion of porous material extends along an entire longitudinal length of the body.

7 . The fluid collection device of claim 1 , wherein the raised portion of porous material extends along less than an entire longitudinal length of the body.

8 . The fluid collection device of claim 1 , further comprising the conduit including an inlet and an outlet, the inlet being positioned within the fluid collection device and the outlet is configured to be fluidly coupled to a fluid storage container.

9 . The fluid collection device of claim 8 , wherein:
the fluid impermeable barrier and one or more of the fluid permeable membrane or fluid permeable support define a reservoir therebetween; and the inlet is disposed in the reservoir.

10 . A fluid collection system, comprising:
a fluid storage container configured to hold a fluid; a fluid collection device fluidly coupled to the fluid storage container, the fluid collection device including:
a fluid impermeable barrier having an outer surface and an inner surface, the inner surface at least partially defining a chamber, the fluid impermeable barrier also defining an opening extending therethrough, the opening configured to be positioned adjacent to a female urethra, the fluid impermeable barrier defining an aperture sized to receive a conduit; and
a porous material at least partially disposed in the chamber, the porous material having a body and a raised portion extending longitudinally along the body and through the opening;
the conduit including an inlet and an outlet, the outlet being fluidly coupled to the fluid storage container, the conduit positioned in the aperture and the inlet positioned in the chamber; and a vacuum source fluidly coupled to one or more of the fluid storage container or the fluid collection device via the conduit, the vacuum source configured to draw fluid from the fluid collection device via the conduit.

11 . The fluid collection system of claim 10 , wherein the raised portion includes a cusp extending away from the body.

12 . The fluid collection system of claim 10 , wherein the raised portion includes a lobe standing off of the body.

13 . The fluid collection system of any of claim 10 , wherein:
the body is substantially cylindrical; and the raised portion extends away from the body at least 5 mm.

14 . The fluid collection system of claim 10 , wherein the porous material includes:
a fluid permeable membrane disposed within the chamber and extending across the opening; and a fluid permeable support disposed within the chamber beneath the fluid permeable membrane, the fluid permeable support including the raised portion thereon.

15 . The fluid collection system of claim 10 , wherein:
the fluid impermeable barrier and one or more of the fluid permeable membrane or fluid permeable support define a reservoir therebetween; and the inlet is disposed in the reservoir.

16 . A method to collect fluid, the method comprising:
positioning a raised portion of a fluid collection device adjacent to a female urethra, the fluid collection device including:
a fluid impermeable barrier having an outer surface and an inner surface, the inner surface at least partially defining a chamber, the fluid impermeable barrier also defining an opening extending therethrough, the opening configured to be positioned adjacent to a female urethra, the fluid impermeable barrier defining an aperture sized to receive a conduit;
a porous material at least partially disposed in the chamber, the porous material having a body and the raised portion extending longitudinally along the body and through the opening; and
the conduit including an inlet and an outlet, the outlet being fluidly coupled to a fluid storage container, the conduit positioned in the aperture and the inlet positioned in the chamber; and
receiving fluid from the female urethra into the fluid collection device; and applying suction with a vacuum source fluidly connected to the conduit effective to suction the fluid from the chamber via the conduit.

17 . The method of claim 16 , wherein the vacuum source is spaced from the fluid collection device and applying suction with the vacuum source includes activating the vacuum source.

18 . The method of claim 16 , wherein positioning a raised portion of a fluid collection device adjacent to a female urethra includes positioning the raised portion between the labia of a wearer.

19 . The method of claim 16 , wherein receiving fluid from the female urethra into the fluid collection device includes receiving the fluid in the porous material.

20 . The method of claim 16 , wherein receiving fluid from the female urethra into the fluid collection device includes wicking the fluid into the chamber via the porous material.
