Abstract
A canister for use in a negative pressure wound therapy system. The canister includes a first fluid chamber, a second fluid chamber, and a filter disposed between the first fluid chamber and the second fluid chamber. The first fluid chamber is configured to receive fluids from a tissue site. The filter is configured to filter the fluids from the tissue site as the fluids move from the first fluid chamber to the second fluid chamber.

A system for treating a tissue site, the system comprising:
- a dressing configured to be disposed at the tissue site;
- a negative-pressure source configured to be fluidly coupled to the dressing and further configured to generate a negative pressure at the tissue site;
- and
- a canister configured to be fluidly coupled between the dressing and the negative-pressure source, the canister comprising:
- a first fluid chamber configured to receive fluids from the tissue site;
- a second fluid chamber configured to store fluids;
- and
- a filter disposed between the first fluid chamber and the second fluid chamber, the filter configured to filter the fluids from the tissue site as the fluids move through the filter from the first fluid chamber to the second fluid chamber.

A method of treating a tissue site, the method comprising:
- disposing a dressing at the tissue site;
- fluidly coupling a negative-pressure source to the dressing;
- fluidly coupling a canister between the negative-pressure source and the dressing, the canister comprising, a first fluid chamber configured to collect fluids from the tissue site;
- a second fluid chamber;
- and
- a filter disposed between the first fluid chamber and the second fluid chamber, the filter configured to filter the fluids from the tissue site as the fluids move through the filter from the first fluid chamber to the second fluid chamber;
- operating the negative-pressure source to generate a negative pressure at the dressing;
- drawing fluids from the tissue site into the first fluid chamber of the canister in
- response to the negative pressure;
- and
- filtering, with the filter, the fluids from the tissue site as the fluids move from the first fluid chamber to the second fluid chamber.
