Abstract
A combination electric motor driven vacuum pump and air compressor unit, particularly adapted to use in medical procedures, is mounted in an insulated cabinet arranged to provide for drawing cooling air into the cabinet through an inlet duct, cause cooling air to flow over an aftercooler part of a compressed air discharge conduit to aftercool compressed air, and cause cooling air to flow through the pump/compressor unit and be discharged from the cabinet. A pressure air receiver tank is mounted in the cabinet and is operably connected to a condensate receiver and a control valve for discharging condensate to an evaporator container connected to the aftercooler conduit part to evaporate condensate. A control circuit includes solenoid actuated valves for controlling vacuum produced by the pump/compressor unit and actuation of a flexible tube clamp mechanism for cutting off vacuum from a vacuum device, such as a cannula, during certain phases of a liposuction medical procedure, for example. A manual vacuum release valve is also connected to the pump/compressor unit for manually releasing vacuum to allow replacement or emptying of a debris collection canister disposed between the flexible tube clamp and the pump/compressor unit suction port. Vacuum pressure may be selectively controlled by controls including a vacuum sensor, a potentiometer controller and a comparator circuit.
