Objective To determine the mode of temperature changes in the electronic bio-temperature-controlled incubators under different external temperature.Methods The physiological saline bags pre-warmed in 20— 24℃ were placed in different electronic bio-temperature-controlled incubators,which kept in a plugged state. Meanwhile,the temperature recorders that had passed the calibration by the metrology department were put in incubators. The electronic bio-temperature-controlled incubators were placed in an external environment with temperatures of up to 43℃,2—8℃,and 20—24℃,respectively,and the temperature recorder values were read. Results Within 6 h,the electronic bio-temperature-controlled incubators,the model of LX-18 X andLX-18 Z,had the similar temperature change trend under extreme temperature,and all could meet the requirements of cold chain transportation. When the temperature was normal,the external environment temperature had the least influence on the thermal insulation effect of the electronic bio-temperature-controlled incubators,the temperature inside the incubators could be maintained smoothly,and the fluctuation was small; when encountering the extreme temperature of high temperature or low temperature,the thermal insulation effect of the electronic bio-temperature-controlled incubators was affected to a certain extent within the controllable range,and the degree of influence becomes larger with time accumulation.Conclusion At extreme ambient temperatures,the electronic bio-temperature-controlled incubators could meet the requirements for blood cold chain transport.
