Abstract: A gas mixing apparatus comprising an oxygen input-source, the oxygen input-source further comprising an oxygen sensor, a gas input-source, the gas input further comprises a first gas flow sensor and a combined gas output-source. The gas output source further comprises a second gas flow sensor. The gas mixing apparatus further comprise an electronic mixing-valve, the electronic mixing valve adapted to be controlled by an input-knob or by a CPU. Wherein, the electronic mixing valve, responds to a CPU, the CPU adapted to receive signals from an accelerometer, an oxygen sensor, a gas flow sensor, an input-knob, a digital input source, and a wireless transceiver; wherein said CPU controls said electronic mixing valve by comparing stored preset values and adjusting said electronic mixing valve through a feedback loop. The method of precisely mixing gas and oxygen comprising the steps of using an electronic mixing valve; said electronic mixing valve adapted to receive processed signals from a CPU.

Abstract: The invention herein applies generally to General-purpose, Surgical and Tracheal suction regulators. In one embodiment of the invention, at least one micro-latching valve is opened and closed by at least one solenoid electromechanical actuator. The micro-latching solenoid valve in turns opens and closes at least one main valve that is connected the hospital vacuum or gas intake conduit. The latching nature of the solenoid, along with its low power activation allows for a battery powered, long-life device. Timing and control of the electromechanical actuator is performed by a low power micro-controller. This provides opportunity for highly accurate timing cycles, user adjustable timing intervals and feedback loop control operations. The invention also features a wireless suction control system of many suction regulators comprising a network.
