Wound treatment apparatuses and methods for controlled delivery of fluids to a wound

Wound-treatment apparatus for treating a wound, comprising:

• a pump cassette having a pump body and a plurality of diaphragms movably coupled to the pump body to form a plurality of chambers, each chamber having a variable volume in response to the stroke of a corresponding diaphragm, wherein the pump body includes an inlet valve for each chamber adapted to receive fluid from a fluid source into the chamber and an outlet valve for each chamber adapted to discharge fluid from the chamber to a wound in response to a motivating force that reduces the volume of the chamber;
• an identifier configurable to store pump information relating to at least one property of at least one of the plurality of diaphragms, the identifier adapted to be readable by an automated reader to provide the pump information;
• and
• a plurality of actuating mechanism, each one adapted to be removably coupled to a corresponding one of the plurality of diaphragms and operable to provide the motivating force to the plurality of diaphragms for moving each one of the plurality of diaphragms by a desired stroke length in response to the pump information.
