Mercury thermometer: generally divided into axillary temperature, oral temperature and anal temperature measurement, in which the mercury end of the thermometer needs to be clamped in the middle of the armpit for about 10 minutes, but it is forbidden for patients with underarm hyperhidrosis and underarm injury. The mercury end of the thermometer should be placed under the tongue and armpit for 3~5 minutes for oral temperature measurement, but it is forbidden for infants, mental disorders and other patients. Anal temperature measurement: insert the mercury end of the thermometer into the anus for 3~4cm, and the measurement time is 3~5 minutes, but it is forbidden for patients with diarrhea and myocardial infarction.
Electronic thermometer: It is more convenient to measure body temperature with electronic probe than traditional mercury thermometer. The thermometer can be directly pointed to the wrist, forehead and other positions for measurement.
Other thermometers: such as infrared thermometers, patients can measure when standing in front of the instrument, which is suitable for crowded occasions. There is also a forehead thermometer, which is generally suitable for children.
Generally speaking, different types of thermometers use different methods and times, so you should read the instructions carefully before using them to understand the usage and precautions.
