    摘要： 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 through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The one-way flow valve can be configured to substantially prevent a flow of gas through the one-way flow valve in a direction of flow away from the pump. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump has been 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.

    摘要： Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

    摘要： Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.
