During a study of the protective effects of cold on kidney cells under conditions of interrupted blood circulation, it was found that attention must be paid to the temperature of kidney tissue in order to prevent cell damage caused by an excessively reduced temperature. The authors correspondingly developed an instrument for the measurement of kidney tissue temperature where thermal sensors located in a needle are able to measure deep temperature in live tissue under conditions of external hypothermia. Thermal sensors were also placed in a hypothermal coil for contact measurement of surface temperature of a cooled kidney and in a duct for supply of cooling medium into a coil. Construction of these devices is described and basic the characteristics of the thermistor and thermocouple sensors for temperature measurement are presented. After evaluation of advantages of the tested sensors, indications regarding their application are given.
在一项关于在血液循环中断的情况下低温对肾细胞保护作用的研究中，发现必须关注肾组织的温度，以防止因温度过度降低而导致细胞损伤。相应地，作者开发了一种用于测量肾组织温度的仪器，其中位于针内的热传感器能够在外部低温条件下测量活体组织的深部温度。热传感器还被放置在一个低温线圈中，用于接触测量冷却肾脏的表面温度，并放置在一个将冷却介质供应到线圈的管道中。描述了这些装置的构造，并介绍了用于温度测量的热敏电阻和热电偶传感器的基本特性。在评估了测试传感器的优点之后，给出了关于它们应用的指征。
