Abstract

The invention concerns a reduced pressure wound treatment apparatus (10). The apparatus has a disposable and replaceable vacuum pump (28) which includes a suction chamber (44) and a suction line (24) which is connected between the suction chamber of the vacuum pump and a porous wound contact means (16) placed in contact with a wound (12) from which wound exudate is to be drawn. The apparatus also includes a re-usable pump actuator (42) arranged externally of the vacuum pump, out of fluid communication with the suction chamber. The actuator is operated to actuate the vacuum pump in order to generate a reduced pressure in the suction chamber. This draws wound exudate from the wound through the wound contact means and suction line into the suction chamber. At the end of a treatment or when the suction chamber is full, the suction chamber can be disposed of and replaced, while the actuator can be re-used.
