1. An electronically controlled suction regulator, comprising:
- a source of vacuum;
a vacuum regulator connected to said source of vacuum;
a generator connected to be driven by said source of vacuum such that said generator produces an electrical current;
an electrically operated valve connected to said vacuum regulator; and
electronic circuitry powered by said electrical current for generating control signals for controlling said electrically operated valve so that said source of vacuum is supplied to a patient for predetermined periods of time.

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.
