Abstract
An apparatus is disclosed for convectively and evaporatively cooling a patient's head. The apparatus includes an upper sheet and a base sheet that are attached at a plurality of locations to form a convective device adaptable to the patient's head. The base sheet includes a plurality of apertures that direct an inflating medium from the convective device toward the patient's head. The base sheet also supports an evaporative cooling element that distributes and delivers a cooling fluid to the patient's head. The fluid is evaporated from the patient's head by the inflating medium exhausted from the convective device. The evaporative cooling element may be constructed in a variety of configurations and may circulate a variety of fluids, which may be pressurized or unpressurized. In operation, an air blower, that may also include a compressor for selectively delivering room temperature or cooled air to the apparatus, is connected to the convective device. The blower delivers air, under pressure, to an inlet opening in the convective device. The pressurized air is distributed throughout the convective device and flows to the patient's head through the apertures in the base sheet.
