Objective To study the effect of designing and application of portable thermometer transceiver and its application. Methods A portable thermometer transceiver was designed and used to measure the temperature of 31,386 patients. Meanwhile, the traditional temperature measurement method was used among 31,378 patients. The two groups were compared in view of time for assigning and collecting the meter. Results The time for assigning the portable thermometer transceiver and receiver was (0.08 ±0.03) min, while that for the traditional measurement method was (1.06 ±0.03) min. There was statistically significant difference between the groups (t=29.231, P<0.001). Conclusion The portable thermometers for temperature measurement can save time and improve the efficiency of nursing staff.
