Abstract
A system and method for pressurizing bags of physiological fluids include a control valve for providing deflation of a bladder that compresses the bags. The toggle portion of the control valve is movable between a first and second position respectively for inflation and deflation of the bladder. When the toggle portion is in the first position, the control valve connects a source of pressurized air to the bladder, and when the toggle portion is in the second position, the control valve allows the bladder to exhaust directly to the atmosphere through an outlet port in the valve. The size of the outlet port is so large that it creates only very little resistance to the discharged air.
