Abstract
A support surface for patient comfort, maintaining a cool skin temperature, or reducing the incidence and promoting the healing of bedsores, includes: (a) a central portion including a hollow, enclosed bladder containing a pre-determined amount of liquid refrigerant with a boiling point between about 23 and about 35 degrees Centigrade; (b) a flexible spacer mechanism contained in the bladder, the spacer mechanism separating an upper bladder wall from a lower bladder wall; and (c) conductive end portions attached to opposite ends of the bladder, the conductive end portions including a flexible heat conductive material layer.
