Abstract
Rescue apparatus and method. The apparatus includes a tear-resistant balloon bound to a frame that is securable to a person. To initiate rescue action, the ballon is inflated by pressurized gas to buoy the attached person at, for example, the surface of the avalanche. The apparatus is formed by a frame with a collar to which the balloon is attached. A filling mechanism for the balloon is positioned within the frame and includes a nozzle valve that operates in accordance with Venturi action.
