Abstract

Claims (41)

1. A fluid collection assembly, comprising:

a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet; and

at least one porous material disposed in the chamber, the at least one porous material including at least one of:

a protrusion extending outwardly from the at least one opening, the protrusion exhibiting a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material, wherein the at least one porous material includes the protrusion before the at least one porous material is exposed to one or more bodily fluids; or

a fluid permeable membrane, a fluid permeable support, and at least one expandable material that expands when exposed to the one or more bodily fluids, the fluid permeable membrane extending across the at least one opening, the fluid permeable membrane positioned between the at least one expandable material and at least a portion of the fluid impermeable barrier, the at least one expandable material positioned between at least a portion of the fluid permeable membrane and the fluid permeable support, wherein an expanded portion of the at least one porous material exhibits a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of the majority of a porous material when the at least one expandable material is expanded.

2. The fluid collection assembly of claim 1 , wherein the at least one porous material extends across the at least one opening and includes the protrusion.

3. The fluid collection assembly of claim 1 , wherein the at least one porous material includes the fluid permeable membrane, the fluid permeable support, and the at least one expandable material, and wherein the at least one expandable material forms an expandable material protrusion after the at least one expandable material is exposed to the one or more bodily fluids.

4. The fluid collection assembly claim 2 , wherein at least one of the protrusion or the expanded portion of the at least one porous material exhibits a generally triangular cross-sectional shape.

5. The fluid collection assembly of claim 1 , wherein the at least one porous material includes the fluid permeable membrane, the fluid permeable support, and the at least one expandable material.

6. The fluid collection assembly of claim 5 , wherein the at least one expandable material includes at least one hydrogel.

7. The fluid collection assembly of claim 5 , wherein the at least one expandable material include a sponge.

8. The fluid collection assembly of claim 5 , wherein the at least one expandable material includes at least one super absorbent polymer.

9. The fluid collection assembly of claim 5 , wherein the fluid permeable membrane includes a gauze.

10. The fluid collection assembly of claim 5 , wherein the at least one expandable material includes a rod and at least a portion of the at least one expandable material is positioned adjacent to the at least one opening and between the fluid permeable membrane and the fluid permeable support.

11. The fluid collection assembly of claim 1 , wherein at least a portion of the at least one porous material exhibits a generally triangular cross-sectional shape at least one of before or after exposing the at least one porous material to the one or more bodily fluids.

12. The fluid collection assembly of claim 1 , wherein at least a portion of the at least one porous material exhibits a generally teardrop-like cross-sectional shape at least one of before or after exposing the at least one porous material to the one or more bodily fluids.

13. The fluid collection assembly of claim 1 , wherein the fluid impermeable barrier exhibits a generally cylindrical shape before exposing the at least one porous material to the one or more bodily fluids.

14. A fluid collection system, comprising:

a fluid collection assembly including:

a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet; and

at least one porous material disposed in the chamber, the at least one porous material including at least one of:

a protrusion extending outwardly from the at least one opening, the protrusion exhibiting a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material, wherein the at least one porous material includes the protrusion before the at least one porous material is exposed to one or more bodily fluids; or

a fluid permeable membrane, a fluid permeable support, and at least one expandable material that expands when exposed to the one or more bodily fluids, the fluid permeable membrane extending across the at least one opening, the fluid permeable membrane positioned between the at least one expandable material and at least a portion of the fluid impermeable barrier, the at least one expandable material positioned between at least a portion of the fluid permeable membrane and the fluid permeable support, wherein an expanded portion of the at least one porous material exhibits a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material when the at least one expandable material is expanded;

a fluid storage container; and

a vacuum source;

wherein the chamber of the fluid collection assembly, the fluid storage container, and the vacuum source are in fluid communication with each other via one or more conduits.

15. A method of forming a fluid collection assembly, the method comprising:

providing at least one porous material, the at least one porous material including at least one of:

a protrusion extending outwardly from the at least one opening, the protrusion exhibiting a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material, wherein the at least one porous material includes the protrusion before the at least one porous material is exposed to one or more bodily fluids; or

a fluid permeable membrane, a fluid permeable support, and at least one expandable material that expands when exposed to the one or more bodily fluids, the fluid permeable membrane extending across the at least one opening, the fluid permeable membrane positioned between the at least one expandable material and at least a portion of the fluid impermeable barrier, the at least one expandable material positioned between at least a portion of the fluid permeable membrane and the fluid permeable support, wherein an expanded portion of the at least one porous material exhibits a shape that does not correspond to a shape of the fluid impermeable barrier and a shape of a majority of the porous material when the at least one expandable material is expanded; and
