Abstract
A patient cooling system comprises a patient enclosure or tent having a coaxial hose connection to a re-circulating air-cooling system. The hose comprises an inner tube to introduce air into the enclosure and an outer tube for the return air. The patient cooling system further comprises a patient-supporting mattress comprising a plurality of inflatable compartments extending transversely across the width of the mattress, which can also be supplied with cooled air. The compartments can be alternately pressurized for pressure relief therapy. Moreover, the compartments can be pressurized either with relatively low pressure cold air from the air cooling system, or with higher pressure air which acts to support the patient, but provides relatively less cooling effect. Radially collapsible, sleeved openings in the tent panel enable connection of conduits or patient care lines to the patient.
