Abstract
A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.
Claims15
A canister for collecting bodily fluids from a fluid collection system for delivering reduced pressure to a tissue site from a source of reduced pressure, the canister comprising:
- a container having a chamber being expandable to receive and collect bodily fluids from the tissue site in response to an application of the reduced pressure;
- an inlet fluidly coupled to the chamber of the container and configured to be in fluid communication with the fluid collection system for delivering the bodily fluids into the chamber of the container;
- an outlet fluidly coupled to the chamber of the container and configured to be in fluid communication with the source of reduced pressure for providing reduced pressure through the chamber of the container to the fluid collection system;
- an absorptive member comprising absorptive layers and wicking layers positioned on opposing sides of each of the absorptive layers, wherein the wicking layers have flow channels for supporting fluid flow across a surface of the absorptive layers;
- and
- at least one spacer between the wicking layers of the absorptive member to maintain a space between adjacent wicking layers under reduced pressure.
