Eksperimental'noe issledovanie termoelektricheskogo ustroystva dlya vnutripolostnoy gipotermii

One of the effective methods of treatment of diseases in otorhinolaryngology, gynecology, proctology, urology and dentistry is intracavitary hypothermia. The implementation of this technique can be carried out through the use of thermoelectric device as a source of cold. This devices are characterized by high efficiency, reliability, environmental friendliness, quietness, accuracy of the dosage of thermal effects, unlimited service life. The design of the thermoelectric device for intracavitary hypothermia, consisting of two thermoelectric batteries (TEB), interconnected by means of an allmetal heat pipe, equipped with an acting applicator and a liquid heat exchanger. Fullscale tests of the device on the experimental stand were carried out. As a result of experimental studies it was found that without load the temperature of the applicator is stabilized after about 4-4,5 min. At the same time, the increase in the current of the additional TEB from 5 to 12 A when the main TEB current is 23 A, reduces the temperature from 237 to 224 K. In the process of carrying out the necessary procedures reducing the temperature of the biological object can be achieved at the supply current of the main and additional TEB, respectively, 23 and 12 A after 2,5 min.
