Abstract

As animals under the effect of myorelaxants or deep anaesthesia lose most of their thermogenesis and cannot compensate heat losses, thermal homeostasis is no longer maintained and hypothermia ensues. In order to maintain a constant temperature the animals must receive their heat from an outer source. An electronic device is described which measures the animal's temperature by a thermistor and, according to the recordings, controls the heating circuit of an ultrathermostat that in turn pumps hot water through a heat exchanger (coils or plastic bag, etc.) and keeps the animal warm. The temperature of the curarized animal is thus maintained at a constant level, varying within the range of +/- 0.2 degrees C (possibly also +/- 0.1 degree C).

摘要

由于处于肌松药作用或深度麻醉状态下的动物失去了大部分产热能力,无法补偿热量损失,热稳态不再维持,体温过低随之而来。为了保持恒定体温,动物必须从外部热源获取热量。本文描述了一种电子设备,该设备通过热敏电阻测量动物体温,并根据记录控制超恒温器的加热电路,超恒温器进而将热水泵入热交换器(盘管或塑料袋等),使动物保持温暖。因此,箭毒化动物的体温得以维持在恒定水平,波动范围在±0.2摄氏度(也可能是±0.1摄氏度)内。
