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

Abstract
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.

18. A wound-treatment apparatus, comprising:
-
a housing configured to be coupled to a pump cassette having a diaphragm and an identifier configured to store information relating to the pump cassette, wherein the information is related to at least one of the diaphragm, the pump chamber, and the fluid disposed in the fluid container; a vacuum source disposed within the housing and operable to apply negative pressure to a wound through a wound dressing; an actuator adapted to be removably coupled to the diaphragm and operable to provide mechanical force to the diaphragm in response to a signal provided by the wound-treatment apparatus; and an automated reader configured to read the identifier when the cassette is coupled to the housing to read the information.

19. A wound-treatment apparatus comprising:
-
a housing configured to be coupled to one or more pump cassettes, each having a diaphragm and an identifier configured to store information relating to the one or more pump cassettes; a vacuum source disposed within the housing and operable to apply negative pressure to a wound through a wound dressing; a plurality of actuators adapted to be removably coupled to the diaphragms and operable to provide mechanical force to the diaphragms in response to a signal provided by the wound-treatment apparatus; and an automated reader configured to read the identifiers when the one or more pump cassettes are coupled to the housing to read the information; wherein the wound-treatment apparatus is configured such that if the one or more pump cassettes are coupled to the housing, the plurality of actuators can be activated to move the diaphragms. - View Dependent Claims (20, 21)
