ABSTRACT:
A wound evacuator is disclosed which is adapted for use with an external negative pressure source to provide continuous fluid evacuation and which includes its own negative pressure source to provide limited time duration evacuation. The evacuator includes a substantially rigid container and an air inflatable member within the container, the container and inflatable member having a combined configuration which avoids unnatural deformation of the inflatable member by the container in at least one direction of expansion of the inflatable member. Means are provided for inflating the inflatable member and controlling the deflation thereof and for controlling the sequence of sealing of the inlet and outlet ports by the inflatable member.
