ABSTRACT:
A valve for a pressure infusion system. The valve includes a body having a first port for being coupled to a source of pressurized fluid, a second port for being coupled to a bladder of the pressure infusion system, a third port for being vented to the atmosphere, and an open interior for connecting the second and third ports to one another and for allowing pressurized fluid to pass therebetween. Each of the second and third ports has a cross sectional area greater than the cross sectional area of the first port to allow pressurized fluid to quickly escape from the interior of the bladder through the second and third ports. A plug is positioned within the body for movement between an inflate position and a deflate position. The first and second ports are open and the third port is blocked when the plug is in the inflate position for allowing inflation of the bladder. The first port is blocked and the second and third ports are opened when the plug is in the deflate position for allowing rapid deflation of the bladder.
