| description | Objective. The purpose of the article is to highlight the results of experimental studies, the measurement technique, as well as the design of a laboratory stand for carrying out field tests of a thermoelectric device (TEC) for stopping bleeding by the method of local freezing of the blood flow zone. Method. An experimental stand and a technique for carrying out measurements of a laboratory sample of a TEU for stopping bleeding by the method of local freezing of the blood flow zone are described. The experimental stand is made on the basis of the measuring equipment of the laboratory of semiconductor thermoelectric devices and devices of Daghestan State Technical University. Result. The graphs of the time dependence of the temperature change of the control points of the laboratory sample of TEC for stopping bleeding by the method of local freezing of the blood flow zone at various supply currents of the thermoelectric battery (TEB) were obtained. The control points were cold and hot junctions of TEB, a simulator of a biological object. Conclusion. The data obtained show that with an increase in the area of blood flow, it takes more time to stop it. An increase in the diameter of the hole with blood flow by an average of 1 mm increases the duration of thrombus formation, which stops bleeding by an average of 20 s. During the experiment, it was found that to ensure the efficient operation of the TEU, it is sufficient to use the commercially available TEB brand ICE- 71. |
