Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.

1. A wound-treatment apparatus, comprising: a pump cassette having a pump body and a diaphragm movably coupled to the pump body to form a chamber having a variable volume in response to the stroke of the diaphragm, wherein the pump body includes an inlet valve adapted to receive fluid from a fluid source into the chamber and an outlet valve 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 the diaphragm, the identifier adapted to be readable by an automated reader to provide the pump information; andan actuating mechanism adapted to be removably coupled to the diaphragm and operable to provide the motivating force to the diaphragm for moving the diaphragm by a desired stroke length in response to the pump information. 2. The wound-treatment apparatus of claim 1, wherein the identifier comprises at least one of a radio-frequency identification (RFD) tag, a barcode, or a magnetic stripe. 3. The wound-treatment apparatus of claim 1, wherein the identifier is a label. 4. The wound-treatment apparatus of claim 1, wherein the identifier is disposed proximate the pump body. 5. The wound-treatment apparatus of claim 1, further comprising an automated reader configured to read the identifier when the actuating mechanism is coupled to the diaphragm to read the pump information. 6. The wound-treatment apparatus of claim 1, wherein the pump information comprises a code adapted to be read by a controller programmed to activate the actuating mechanism. 7. The wound-treatment apparatus of claim 1, wherein the actuating mechanism comprises an actuator activated by a solenoid. 8. The wound-treatment apparatus of claim 1, wherein the actuating mechanism comprises mechanical device adapted to motivate the diaphragm. 9. The wound-treatment apparatus of claim 1, wherein the at least one property related to diaphragm includes one or more of the diameter of the diaphragm, the area of the diaphragm, the stroke of the diaphragm, and the change in volume in the chamber caused by a stroke of the diaphragm. 10. The wound-treatment apparatus of claim 1, wherein the inlet valve and outlet valve each comprises at least one of a ball valve, a duckbill valve, or an umbrella valve. 11. The wound-treatment apparatus of claim 1, wherein the diaphragm is operable to alternately increase and decrease the volume of the chamber. 12. The wound-treatment apparatus of claim 11, wherein the inlet valve is open and the outlet valve is closed when the diaphragm increases the volume of the chamber. 13. The wound-treatment apparatus of claim 11, wherein the outlet valve is open and the inlet valve is closed when the diaphragm decreases the volume of the chamber. 14. The wound-treatment apparatus of claim 11, wherein the actuator is operable to provide motivating force to the diaphragm to alternately increase and decrease the volume of the chamber. 15. The wound-treatment apparatus of claim 1, wherein the fluid source is a fluid container adapted to be seated in the pump cassette. 16. The wound-treatment apparatus of claim 1, further comprising a conduit having a first end coupled to the inlet valve of the pump body and a second end configured to be coupled to the fluid source. 17. The wound-treatment apparatus of claim 16, wherein the fluid source is a fluid container adapted to be seated in the pump cassette. 18. The wound-treatment apparatus of claim 17, further comprising the fluid container and a fluid disposed in the fluid container. 19. The wound-treatment apparatus of claim 1, further comprising a conduit having a first end coupled to the outlet valve and a second end configured to be coupled to a wound dressing disposed adjacent the wound. 20. The wound-treatment apparatus of claim 1, further comprising a support device coupled to the pump body and a receptacle configured to receive the fluid source. 21. The wound-treatment apparatus of claim 1, further comprising a vacuum source operable to apply negative pressure to a wound. 22. 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; anda 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. 23. The wound-treatment apparatus of claim 22, further comprising a controller coupled to the plurality of actuating mechanism and configured to activate the actuating mechanism. 24. The wound-treatment apparatus of claim 23, wherein the controller is configured to activate the plurality of actuating mechanism at least simultaneously or sequentially.
