Abstract

A cartridge for a negative pressure wound therapy pump unit, the cartridge being configured to releasably attach to a pump body of the negative pressure wound therapy pump unit. The cartridge provides an interface between the pump body and a collection canister which includes filters configured to capture compounds likely to cause odours in the pump system. The cartridge may include seals for sealing between the cartridge and the pump body, and between the cartridge and the collection canister. The cartridge may also provide ports to interface a pump exhaust to atmosphere, and for a negative pressure sensor.
