An airflow cover for controlling the body temperature of a patient covers a portion of the patient\s body and provides a generalized thermal bathing of the covered portion through the delivery of a temperature controlled gas mixture to the covered portion. The cover is formed from a series of inflatable tubes which are joined together in a parallel array having an upper surface facing away from the patient\s body and an oppositely directed lower surface which faces the covered portion of the patient\s body. An entry port is provided through the upper surface and into one tube, transverse ports open between the tubes, and exit ports are formed in the lower surface. A thermally controlled gas mixture is introduced through the entry port, circulates in the tubes by means of the transverse ports and inflates the tubes, and exits through the exit ports in the direction of the covered body portion to provide the desired thermal bathing.

A cover for delivering a diffuse medium flow to a human body, comprising: an inflatable cover housing including a plurality of inflatable hollow tubes, each tube having a rounded upper portion and a flattened lower portion, joined in a substantially parallel array to form a substantially smooth lower cover surface including said lower tube portions for facing a body to be covered and a quilted upper cover surface including said upper tube portions for facing away from said body; an entry port in said upper surface for admitting an inflating medium into said housing; transverse openings connecting the interior of each tube with the interior of at least one other adjacent tube in said array for conducting an inflating medium into all of said tubes to inflate said housing; and exit ports formed in the flattened portion of each of said tubes for, when said housing is inflated, permitting said medium to flow out of said housing through said smooth lower surface. A cap for controlling the temperature of the head of a reclining person, comprising: an inflatable annular tube forming a central opening for encirclingly fitting to the head of a person reclining on a support surface and for being inflated to lift said head from said surface; a sheet of material attached to one side of said annular tube over said central opening to form a recess for receiving substantially the top of a head when said head extends into said recess through said central opening; an outer surface on said tube; an entry port on said tube outer surface for admitting a temperature-controlled, inflating medium into said tube; an inner surface in said tube\s central opening; exit ports in said inner surface for, when said tube is inflated with an inflating medium, conducting said inflating medium from said tube into said recess; and an exit port, substantially smaller than said central opening, in said material sheet for venting an inflating medium from said recess to an external environment.
