Abstract
A hyper-hypothermia disposable blanket for use by medical personnel warms or cools a patient by a stratum of temperature controlled and filtered air. The blanket comprises a bottom layer of air pervious non-woven material and a top layer of air impervious material. The top layer is sealed at its edges to the bottom layer to form a chamber therebetween. A set of longitudinal seals within the chamber is used to create air flow channels and a manifold. A receptacle opening is also provided in the top layer near a foot end to detachably receive an air hose such that temperature controlled air passes into the manifold and is then directed to flow primarily through outermost air flow channels and eventually into an innermost air flow channel. The air flow creates a build up of pressurized air in the chamber which ultimately causes a stratum of air having a substantially uniform temperature to flow through the bottom layer of the blanket and onto the patient. The air which contacts the patient is filtered and is substantially uniform temperatured air because of the air flow channels and nature of the air pervious material.
