1. A system for delivering fluid to a wound dressing, the system comprising:
a negative pressure source coupled to the wound dressing; a fluid flow device in fluid communication with the wound dressing; a reservoir coupled to the negative pressure source and in fluid communication with the wound dressing; a vent on the reservoir; a valve between the wound dressing and the reservoir; a control device configured to control a fluid flow from the fluid flow device; and a pressure sensor coupled to the wound dressing and to the control device, the pressure sensor configured to send a control signal to the control device when the pressure sensor detects a predetermined pressure at the wound dressing; and wherein the negative-pressure source is configured to evacuate the wound dressing; the vent is configured to open the reservoir to atmosphere; the valve is configured to restrict fluid flow to the reservoir when the reservoir is not at a negative pressure; and the control device is configured to deliver fluid from the fluid flow device to the wound dressing until the pressure sensor sends the control signal.
