Abstract
The electronic circuit includes switch means responsive to the pressure within a first chamber of a dynamic pressure wave appliance for generating an enabling signal when a predetermined pressure level in the first chamber has been reached. A transducer is provided to generate a signal representative of the pressure within a second chamber of the appliance. The electronic circuit includes means for generating a signal representing a first predetermined pressure level and a second predetermined pressure level in the second chamber when the enabling signal is generated. A comparator is responsive to the predetermined pressure level signals and the transducer signal for generating control signals to a solenoid. The solenoid is connected to appropriate valves for regulating the pneumatic control circuit. The electronic control circuit will cause a dynamic pressure wave appliance to apply a pressure to a human or animal extremity which begins at the most distant end and travels up the extremity in the nature of a pressure wave.
