药典规定的热原检查,每只家兔须用肛温计手工测温5次或6次,操作烦琐费时。为提高工作效率,国内已有自制自动测温装置的报道[药检工作通讯9(2):108,1979],我们参考有关资料,制成了一台家兔自动测温装置,用于热原检查工作。该装置具有感温灵敏、结果准确,操作方便等优点。通过一年多的测温使用,性能良好,深受操作者的欢迎。这台装置是通过电桥平衡原理,利用热敏电阻与温度变化之间的关系来自动测量家兔体温的。温度变化在电流表上显示。代替了手工测温。并可根据需要,装配若干探头(本装置
Pharmacopoeia provisions of the pyrogen test, each rabbit shall be manually measured with anus temperature meter 5 or 6 times, cumbersome and time-consuming operation. In order to improve work efficiency, there are reports of self-made automatic temperature measurement devices in our country [Drug Testing Newsletter 9 (2): 108, 1979]. With reference to relevant information, we made a rabbit automatic temperature measurement device for pyrogen checking work. The device is sensitive to temperature, the results are accurate, easy to operate and so on. Through more than a year of temperature measurement, good performance, by the operator’s welcome. This device is based on the bridge balance principle, the use of thermistor and temperature changes in the relationship between the automatic measurement of body temperature in rabbits. The temperature change is shown on the ammeter. Instead of manual temperature measurement. And according to the need to assemble a number of probes (the device
