Abstract:
A multi-function air flow generator generating air in a bladder, comprising:an air amplifier having a pressurized air inlet, an ambient air inlet, and an air outlet;a first valve having an inlet for receiving pressurized air and an outlet operably coupled with the air amplifier pressurized air inlet;means for selectively actuating the valve to produce a preselected flow of pressurized air into the air amplifier pressurized air inlet, wherein the preselected flow of pressurized air into the air amplifier pressurized air inlet generates a predetermined flow of air through the air amplifier outlet; andmeans for periodically sampling an air pressure in the bladder adapted to be positioned about a subject, the bladder operably connected with the air outlet, and the sampling means operably connected with the means for selectively actuating.
