20140150179 | HEATED AIR CUSHION COVER - A heated air cushion cover, especially for heat regulation of patients during surgeries, having at least one first material layer connected to at least perforated second material layer so as to form at least one hollow chamber through which an air stream can flow to the outer, patient side of the second material layer is improved by a homogeneous warm air output being produced on the patient side. The homogeneous warm air output is attained by an air-permeable third material layer being at least partially connected to the outer side of the second material layer. The third material layer diffusely distributes the air stream penetrating the perforations of the second material layer upon passing through the third material layer. | 06-05-2014 |
