Patent ID: 7497870

Claim:
System for providing a fluid to a patient temperature regulating blanket comprising: a temperature regulating blanket; an outlet for establishing a fluid path to said patient temperature regulating blanket; a fluid mover for directing the fluid to said outlet; a controller for controlling the flow rate of the fluid to said outlet; at least one sensor located relative to said outlet adapted to sense the pressure of the fluid at said outlet; and a circuit for utilizing the sensed pressure of the fluid from said sensor to instruct said controller to, if needed, vary the flow rate of the fluid to said outlet for maintaining the sensed pressure substantially at a preset pressure so that the blanket is property inflated with the fluid to effect an optimal clinical temperature environment for a patient using the blanket; wherein said fluid is air and wherein said sensor is positioned away from said outlet but in fluid communication with the air in said outlet for sensing the pressure of the air at said outlet, said sensor further being in communication with atmospheric pressure, said sensor comparing the sensed pressure at said outlet with the sensed atmospheric pressure for outputting a difference signal to said circuit.
