Abstract

Embodiments disclosed herein include fluid collection assemblies with at least one securement body. In an embodiment, a fluid collection assembly is disclosed. The fluid collection assembly includes a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet. The fluid collection assembly also includes at least one porous material disposed in the chamber and at least one securement body configured to limit movement of the fluid collection assembly relative to a region about a urethral opening of a patient. The at least one securement body includes at least one of a plurality of fibers exhibiting an average lateral dimension of about 5 μm or less, a plurality of suction cups, or at least one friction material exhibiting a coefficient of static friction that is greater than at least a portion of the at least one porous material.

Claims (12)

1. A fluid collection assembly, comprising: a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet; at least one porous material disposed in the chamber; and at least one securement body configured to limit movement of the fluid collection assembly relative to a region about a urethral opening of a patient, the at least one securement body including: a plurality of fibers exhibiting an average lateral dimension of about 5 μm or less, the plurality of fibers extend from at least one exterior surface of the fluid collection assembly, at least most of the plurality of fibers extend from the at least one exterior surface at an average angle that is oblique relative to the at least one exterior surface, the at least one securement body further including a plurality of branches extending from or attached to at least some of the plurality of fibers, at least some of the plurality of branches exhibiting an average diameter of 300 nm to 2 μm, one or more of the plurality of branches extending from or attached to a portion of one of the plurality of fibers that is spaced from a terminal end of the one of the plurality of fibers, wherein the terminal end of the one of the plurality of fibers is an end of the one of the plurality of fibers farthest spaced from the at least one exterior surface.

2. The fluid collection assembly of claim 1 , further comprising a base and a sheath, the base including a substrate having a top surface and a bottom surface opposite the top surface, the top surface attached to one or more other components of the fluid collection assembly, the bottom surface attached to the at least one securement body.

3. The fluid collection assembly of claim 1 , wherein the at least one securement body is attached to or integrally formed with at least a portion of a surface of the fluid impermeable barrier that is opposite the at least one opening.

4. The fluid collection assembly of claim 1 , wherein the at least one securement body includes a support attached to one or more components of the fluid collection assembly, the plurality of fibers extending from the support.

5. The fluid collection assembly of claim 1 , wherein the plurality of fibers are directly attached to one of: at least one outer surface of the fluid impermeable barrier, wherein the at least one outer surface is opposite a surface of the fluid impermeable barrier that defines the chamber; or a bottom surface of a base, wherein the base includes a top surface opposite the bottom surface, a portion of the top surface attached to a sheath, the sheath including the fluid impermeable barrier.

6. The fluid collection assembly of claim 1 , wherein the plurality of fibers are integrally formed with one of: at least one outer surface of the fluid impermeable barrier, wherein the at least one outer surface is opposite a surface of the fluid impermeable barrier that defines the chamber; or a bottom surface of a base, wherein the base includes a top surface opposite the bottom surface, a portion of the top surface attached to a sheath, the sheath including the fluid impermeable barrier.

7. The fluid collection assembly of claim 1 , wherein the average angle is less than 45°.

8. The fluid collection assembly of claim 1 , wherein the at least one securement body includes a support attached to and distinct from a substrate, the plurality of fibers attached to or integrally formed with the support.

9. The fluid collection assembly of claim 1 , wherein: the at least one opening includes an elongated opening configured to be positioned adjacent to female anatomy; the at least one porous material extends across the elongated opening; and the at least one securement body is positioned adjacent at least to portions of the fluid impermeable barrier defining the elongated opening, at least the portion of the at least one securement body adjacent to the elongated opening including the plurality of fibers.

10. The fluid collection assembly of claim 2 , wherein: the at least one opening includes an elongated opening configured to be positioned adjacent to female anatomy; the at least one porous material extends across the elongated opening; and the at least one securement body is positioned adjacent at least to portions of the fluid impermeable barrier opposite the elongated opening, at least the portion of the at least one securement body opposite the elongated opening including the plurality of fibers.

11. The fluid collection assembly of claim 1 , wherein at least some of the plurality of branches exhibit an average diameter of 500 nm to 2 μm.

12. A fluid collection system, comprising: a fluid storage container configured to hold one or more bodily fluids therein; a fluid collection assembly including: a fluid impermeable barrier at least defining a chamber, at least one opening, and a fluid outlet; at least one porous material disposed in the chamber; and at least one securement body configured to limit movement of the fluid collection assembly relative to a region about a urethral opening of a patient, the at least one securement body including: a plurality of fibers exhibiting an average lateral dimension of about 5 μm or less, the plurality of fibers extend from at least one exterior surface of the fluid collection assembly, at least most of the plurality of fibers extend from the at least one exterior surface at an average angle that is oblique relative to the at least one exterior surface, the at least one securement body further including a plurality of branches extending from or attached to at least some of the plurality of fibers, at least some of the plurality of branches exhibiting an average diameter of 300 nm to 2 μm, one or more of the plurality of branches extending from or attached to a portion of one of the plurality of fibers that is spaced from a terminal end of the one of the plurality of fibers, wherein the terminal end of the one of the plurality of fibers is an end of the one of the plurality of fibers farthest spaced from the at least one exterior surface; and a vacuum source in fluid communication with the fluid storage container and the fluid collection assembly, the vacuum source configured to draw the one or more bodily fluids from the fluid collection assembly and deposit the one or more bodily fluids in the fluid storage container via one or more conduits.
