Abstract
A method and apparatus for providing negative pressure at a wound site. The apparatus includes a negative pressure reservoir and a reservoir valve for selectively connecting the reservoir to a wound chamber at a wound site. In particular, but not exclusively, the present invention relates to an apparatus including a source of negative pressure which acts as a negative pressure reservoir to continually or repeatedly 'top up' an applied negative pressure so that negative pressure applied at a wound site can be maintained within desired limits for a relatively long period of time.
