Abstract
An example fluid collection assembly includes a fluid impermeable layer that at least defines a chamber, at least one opening, and a fluid outlet. The fluid collection assembly includes at least one porous material disposed in the chamber and a multiple lumen conduit disposed in the at least one porous material. The multiple lumen conduit includes fluid lumen and a shape memory lumen having a shape memory material retained therein by a stop plug and an end plug.
Claims20
A fluid collection assembly, comprising:
- a fluid impermeable layer defining:
- a chamber therein;
- at least one opening therethrough;
- and
- a fluid outlet;
- at least one porous material disposed in the chamber;
- a conduit disposed in the at least one porous material, the conduit including a multiple lumen configuration having a fluid lumen and a shape memory lumen;
- a shape memory material disposed in the shape memory lumen;
- and
- a stop plug and end plug disposed in the shape memory lumen, wherein the stop plug and end plug are disposed at opposite ends of the shape memory material in the shape memory lumen to prevent longitudinal movement of the shape memory material within the shape memory lumen.
A fluid collection system, comprising:
- a fluid collection assembly including:
- a fluid impermeable layer defining:
- a chamber therein;
- at least one opening therethrough;
- and
- a fluid outlet;
- at least one porous material disposed in the chamber;
- a conduit disposed in the at least one porous material, the conduit including a multiple lumen configuration having a fluid lumen and a shape memory lumen;
- a shape memory material disposed in the shape memory lumen;
- and
- a stop plug and end plug disposed in the shape memory lumen, wherein the stop plug and end plug are disposed at opposite ends of the shape memory material in the shape memory lumen to prevent longitudinal movement of the shape memory material within the shape memory lumen;
- a fluid storage container fluidly connected to the fluid collection assembly via a first conduit;
- and
- a vacuum source fluidly connected to the fluid storage container via a second conduit effective to provide suction from the vacuum source to the chamber of the fluid collection assembly.
A method of collecting bodily fluid using a fluid collection assembly, the method comprising:
- forming the fluid collection assembly into a selected shape by bending a shape memory material therein, the fluid collection assembly including:
- a fluid impermeable layer defining:
- a chamber therein;
- at least one opening therethrough;
- and
- a fluid outlet;
- at least one porous material disposed in the chamber;
- a conduit disposed in the at least one porous material, the conduit including a multiple lumen configuration having a fluid lumen and a shape memory lumen;
- the shape memory material disposed in the shape memory lumen;
- and
- a stop plug and end plug disposed in the shape memory lumen, wherein the stop plug and end plug are disposed at opposite ends of the shape memory material in the shape memory lumen to prevent longitudinal movement of the shape memory material within the shape memory lumen;
- positioning the opening of the fluid collection assembly adjacent to or on a urethra of a wearer;
- and
- receiving bodily fluid of the wearer in the fluid collection assembly.
