  • Fluid drive mechanism for a therapeutic treatment system
    Patent number: 6176869
    Abstract: A system for therapeutically treating a desired region of a patient's body by circulating a nonambient temperature treatment fluid through a pad positioned on the treatment region. The system is provided with a fluid drive mechanism including a flow control assembly and a pump for delivering a drive fluid to the flow control assembly. The flow control assembly houses a pressurizing chamber having a drive fluid inlet and outlet and a treatment fluid inlet and outlet. A drive fluid outlet valve and treatment fluid inlet valve are provided to selectively restrict flow through the drive fluid outlet and treatment fluid inlet, respectively. Operation of the flow control assembly initiates with both the drive fluid outlet valve and treatment fluid inlet valve in an open position, enabling the pressurizing chamber to receive fresh treatment fluid in a receiving mode.
