Abstract
Some embodiments comprise a pump assembly for reduced pressure wound therapy, comprising a housing, a flow pathway through the pump, one or more valves in communication with the flow pathway, a pump supported within or by the housing, and a one-way flow valve in fluid communication with the pump. The pump assembly can have a pressure sensor in communication with the flow pathway, and at least one switch or button supported by the housing in communication with a pump controller. The one-way flow valve can substantially prevent a flow of gas therethrough in a direction of flow away from the pump. The pump can be sterilized following the assembly of the pump such that an inside and an outside of the housing, the flow pathway, the one or more valves, the pump, the controller, the battery compartment, and the at least one switch or button have been sterilized.
