Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
134 words
A therapeutic device, comprising: a sleeve for covering a portion of a patient's body and having flexible walls defining an inner space to receive liquid; means for changing the temperature of said liquid; a conduit system connecting the sleeve space and the changing means in a pair of paths; pump means for circulating the liquid between the sleeve space and changing means through the conduit system; and means for pressurizing the liquid in said sleeve space comprising, a receptacle having a chamber, a container in the receptacle chamber and having flexible walls defining a cavity containing liquid and communicating with the conduit system and sleeve space, and means for pressurizing the receptacle chamber outside said container to inject a desired amount of liquid from the container cavity into the conduit system and sleeve space.
Claim 2
Dependent Claim
134 words
