摘要:
A method and apparatus are disclosed for providing negative pressure at a wound site. The apparatus includes a suction pump for generating negative pressure, a negative pressure reservoir, a valve element arranged to selectively provide a fluid communication path between the reservoir and the wound site while a negative pressure in the negative pressure reservoir is greater than a threshold negative pressure, to thereby provide a desired negative pressure at the wound site, and wherein in response to a pressure in the negative pressure reservoir decreasing to the threshold negative pressure, the suction pump is operable to re-establish an initial negative pressure in the negative pressure reservoir.
