摘　　要：玻璃体温计和电子体温计是目前最为常用的用来测量体温的计量器具,其稳定性较好,得到广泛使用。目前使用比较法检校体温计,系统组成复杂,不易携带,难以在体温计使用现场检校体温计。37℃为人体体温附近温度点,设计开发便携式37℃固定点装置,通过定点法复现37℃。复现37℃温坪并对温坪保持时间及温坪稳定性与复现性进行研究,从而提供稳定可靠的体温计现场检校用标准装置,并可作为小型次级固定装置与其他温度固定点装置配套使用。Currently, comparison method is used to calibrate clinic thermometers.The calibration system includes electrical measuring instruments, temperature sources, standard thermometers, etc.The equipment composition is complex, with poor portability and complex system operations.Thus, itis difficult to calibrate clinic thermometers on-site.37 ℃ is the temperature point near the human body temperature.Designing and developing the portable 37 ℃ fixed point Apparatus to reproduce 37 ℃ by using the fixed point method.Reproducing the 37 ℃ temperature plateau and research the temperature plateau retention time, stability, and reproducibility.This provides a stable and reliable standard device for on-site calibration of clinic thermometers, and can be used as a miniature secondary fixing device in conjunction with other temperature fixing point devices.
