Objective:To determine whether there is any difference between the temperature reading measured by the dynamic distant thermometer and mercury thermometer.Method:The body temperatures in the 100 emergency patients were measured by the dynamic distant thermometer and mercury thermometer.The reading data were analyzed statistically.Results:The average body temperatures with the dynamic distant thermometer was 36.9±0.7°C,which was no significant difference with the results measured by mercury thermometer(36.8±0.7°C,P0.05).The body temperature measured by dynamic distant thermometer was correlated highly with the mercury thermometer(r=0.981,P0.001).Conclusion:The dynamic distant thermometer is an accurate method for measuring body temperature,and maybe safer and easy use than the mercury thermometer in the daily clinical practice.
