Abstract
An electronic vacuum suction regulator for regulating the vacuum applied to a patient is disclosed in which the vacuum source generally present in patient rooms in a hospital is utilized to drive an air motor which is connected to an AC generator to produce an alternating current which is then converted to a regulated DC current and used to operate a microprocessor and associated circuitry. The programmed microprocessor operates an electrical valve which turns the suction vacuum to the patient on and off and also provides a display of desired parameters by means of a lighted LCD display. The microprocessor may be programmed by means of an on-board keyboard.
