Claim 0:
1. A method of providing reduced pressure treatment to a tissue site, the method comprising:
storing a negative pressure within a first reservoir with a pump;
delivering a desired negative pressure from a second reservoir fluidically connected to the tissue site, wherein the first reservoir and the second reservoir are connected in series by a single conduit adapted to provide fluid communication between the first reservoir and the second reservoir; and
responsive to a pressure difference between the second reservoir and the first reservoir, reducing pressure within the second reservoir by allowing fluid communication between the first reservoir and the second reservoir,
wherein reduced pressure is communicated from the pump through a first valve to the first reservoir and subsequently through a second valve to the second reservoir, and
wherein the pump, the first valve, the first reservoir, the second valve, and the second reservoir are arranged in series along the single conduit.
