Abstract
An example fluid collection assembly includes a fluid impermeable layer. The fluid impermeable layer at least defines a chamber, at least one opening that allows bodily fluids to enter the chamber, and a fluid outlet that allows the bodily fluids to be removed from the chamber. The fluid collection assembly also include a porous material at least partially disposed in the chamber. The porous material includes a hydrophilic fluid permeable outer layer and a fluid permeable inner layer. The fluid permeable inner layer includes at least one of a foam or a non-woven material.
Claims21
A fluid collection assembly, comprising:
- a fluid impermeable layer defining at least a chamber, at least one opening, and a fluid outlet;
- a porous material at least partially disposed in the chamber, the porous material including:
- a hydrophilic fluid permeable outer layer including at least one of bamboo, treated polypropylene, or treated polyethylene;
- and
- a fluid permeable inner layer including at least one of a non-woven material or a foam.
A method to collect bodily fluids, the method comprising:
- positioning at least one opening of a fluid collection assembly adjacent to a female urethral opening, the fluid collection assembly including:
- a fluid impermeable layer defining at least a chamber, the at least one opening, and a fluid outlet;
- a porous material at least partially disposed in the chamber, the porous material including:
- a hydrophilic fluid permeable outer layer including at least one of bamboo, treated polypropylene, or treated polyethylene;
- and
- a fluid permeable inner layer including at least one of a foam or a non-woven material;
- and
- receiving bodily fluids from the female urethral opening into the chamber.
A method to form a fluid collection assembly, the method comprising:
- providing a porous material, the porous material including a hydrophilic fluid permeable outer layer and a fluid permeable inner layer, the hydrophilic fluid permeable outer layer including at least one of bamboo, treated polypropylene, or treated polyethylene, the fluid permeable inner layer including at least one of a nonwoven material or a foam;
- and
- disposing the porous material through at least one opening and into a chamber, the at least one opening and the chamber defined by a fluid impermeable layer, the fluid impermeable layer defining a fluid inlet.
