A contact area of the biological tissue is cooled down at a rate of at least 180 K/min to -190 to -160 DEG C, after that it is rewarmed at a rate of 100 to 240 K/min to -70 to -20 DEG C with a subsequent rewarming at a rate of 10 to 25 K/min 15 to -5 to +5 DEG C and further rewarming up to the body temperature, the total time of controlled rewarming being shorter than 5 minutes. A device for carrying out this process consists of an operating apparatus with a built in container of cooling medium and operating instrument and control unit. The control unit is formed by a controlling microprocessor (1) coupled to electronic switches (4) of an electromagnetic valve (8) of the heat exchanger (17), heating (9) of the exchanger (17), further heating (11) of heater (13) of outlet gases and pressurized heating and the controlling microprocessor (1) is further connected to a measuring unit (5) coupled to a thermometer (10) of the heat exchanger (17), further thermometer (12) of heater of outlet gases, manometer (14) of the container, level indicators (15) and a further thermometer (16) of the pressurized heating. The controlling microprocessor (1) is coupled to an independent power supply (3) and external memory (2) and that is further connected to a display unit and keyboard (7). |
