Abstract
A mechanical vacuum dressing comprising: a first valve layer comprising a first one-way valve; a second valve layer comprising a second one-way valve; the first valve layer being joined to the second valve layer so as to define a chamber therebetween; the first one-way valve being configured to admit fluid into the chamber through the first one-way valve but prevent fluid from exiting the chamber through the first one-way valve; the second one-way valve being configured to exhaust fluid from the chamber through the second one-way valve but prevent fluid from entering the chamber through the second one-way valve; and the second valve layer comprising an elastomeric material such that (i) when the second valve layer is moved away from the first valve layer, the volume of the chamber is increased, and (ii) when the second valve layer is thereafter released, the second valve layer moves back towards the first valve layer and the volume of the chamber is decreased.
