Abstract
A negative pressure wound therapy (NPWT) device includes a canister, a pump, a filter, and a control unit. The canister is configured to collect wound exudate from a wound site. The pump is fluidly coupled to the canister and configured to draw a vacuum within the canister by pumping air out of the canister. The filter is positioned between the canister and the pump such that the air pumped out of the canister passes through the filter in a first direction. The control unit is configured to operate the pump and to purge the filter by causing airflow through the filter in a second direction, opposite the first direction.
