SU446015A1 - Hypothermic device - Google Patents

Description

The invention of Otoshito to Medah is not. A hypothermic device is known, which contains a vortex tube and a distributor of heat transfer medium over the old covers of the cooled part 1 ate, and a receiver of the spent heat transfer medium. However, this device provides a low hypothermic effect of treatment. In order to increase the hypothermic effect of treatment, the proposed device is equipped with a heat exchanger formed by pipe finning and a receiver of spent heat carrier, made in the form of a confuser, passing into the diffuser on the NI TK70Y fins. FIG. I schematically shows a hypothermic device; Fig, 2 - vortex tube, section. The device contains a vortex tube I, equipped with fins 2, the spri separates spruce 3 heat carrier | on the outer covers of the body part to be cooled, the core 4 of the used heat carrier and the heat exchanger. The heat exchanger is formed by the finning of the tube I and the receiver 4, made in the form of a confuser, passing into the diffuser at the section of the finned tube. When cooling the head, the device works as follows. Compressed air: with the ambient temperature when the shut-off valve 5 is opened through pipe 6, it shines into pipe I. A cold stream of air from this pipe through valve 3 is distributed evenly distributed by the stream of the head. After contacting about the cooled surface of the head, a cold stream of air falls into the confused part of the receiver 4. To prevent leakage of the cold stream, a seal 7 is put on the patient's head. From the confuser, the cold flow 1 has passed.
