Abstract
Hypothermia therapy apparatus comprises an inflatable blanket having a cavity therein, and a neck extending outwardly of the perimeter of the blanket body, the interior of the neck being in communication with the cavity. A nozzle is also provided, the forward portion of the nozzle being receivable in the outer end of the neck, and the rearward portion of the nozzle is connectable with a source of air. The nozzle includes an engagement mechanism for engaging at least a portion of the exterior surface of the neck. The engagement mechanism comprises a spring clip normally biased in the closed position and selectively openable to receive a portion of the neck thereunder. The forward portion of the nozzle is frusto-conical to facilitate insertion into the open end of the neck, and the neck is dimensioned to loosely engage the intermediate portion of the nozzle. A connector is provided for removably connecting an air hose to the rearward portion of the nozzle. The nozzle and the connector are rotatable relative to each other about their longitudinal axes, to prevent twisting of the blanket when the nozzle is attached to the neck.
