A flexible sheet 1 contains flexible fluid-carrying conduits 2 which connect to a temperature regulation device 7 and a pump. Preferably the conduits are surrounded by a gel 4 containing glycol or glycerine which conducts heat to or from the conduits and cushions them. A watertight outer casing 5 holds the gel in place. The conduits may be plastic tubing which extends through the interior of the casing arranged in a series of loops 3 and is connected by inflow and outflow tubes 6 to a regulation device containing two thermoelectric Peltier devices having their faces in opposition. A water-based heat transfer fluid is cooled or heated by the devices and pumped through the tubing. The sheet may be used as a cooling (or warming) blanket for a bed (figure 4), to cool a car seat (figure 5), to cool a pet animal's bed (figure 6) and to wrap round all or part of a patient requiring local or general control of body temperature. |
