THERMOELECTRIC DEVICE FOR THERMAL IMPACT ON PERSON'S ARM Russian patent published in 2015 - IPC A61F7/00 H01L35/28 F25B21/02 

FIELD: medicine.

SUBSTANCE: thermoelectric device for the thermal impact on a person's arm contains a temperature irritant. Thermoelectric modules of the temperature irritant are built into a flexible elastic base with holes for their installation and are connected to a programmable power source by means of electric cables. The holes are located in one row along the base length. The base is provided with the Velcro fastener on edges and is made in the form of two cloths from a synthetic elastic fabric, sewn to each other with capron thread on the perimeter of the installed in them thermoelectric modules at a 2-3 mm distance from their edges. A part of the fabric overlaps surfaces of the thermoelectric modules, covering 2-3 mm of the latter on the perimeter. Internal thermocouple junctions of the thermoelectric modules face the person's arm and are brought into thermal contact with a flexible heat-equalising plate through heat-conductive paste. External thermocouple junctions of the thermoelectric modules through the heat-conductive paste contact with thin-walled flexible reservoirs, filled with a melting working substance with the melt point of 35-45°C. The reservoirs play the role of heat removal and are sewn to the base on their angles with the capron thread. The base from the side of location of the external thermocouple junctions of the thermoelectric modules on its entire area is brought into tight mechanical contact with a cuff, connected with a blower by means of a tube.

EFFECT: application of the invention will make it possible to simplify the device construction and reduce its overall dimensions and weight.
