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

摘要

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 pump cassette for use with a wound-treatment apparatus, comprising:
a pump body having a chamber with a variable volume, an inlet valve in fluid communication with the chamber and adapted to receive fluid disposed in a fluid container, and an outlet valve in fluid communication with the chamber and adapted to deliver the fluid to a wound; a diaphragm movably coupled to the pump body to vary the volume of the chamber in response to a mechanical force; and an identifier configured to store information relating to at least one property of the pump cassette, wherein the at least one property is related to at least one of the diaphragm, the pump chamber, and the fluid disposed in the fluid container, the identifier being readable by an automated reader to provide the information; wherein the pump cassette is configured to be removably coupled to the wound-treatment apparatus and adapted to receive a signal from the wound-treatment apparatus to provide the mechanical force to the diaphragm.
