When using a thermometer to measure body temperature, ensure the accuracy and reliability of the thermometer and operate it correctly according to the instructions. At the same time, attention should be paid to safe use to avoid risks such as mercury poisoning caused by damage or misuse. If multiple people use the same thermometer, ensure thorough disinfection before each use.

After using the thermometer, it should be disinfected. For mercury thermometers, you can first rinse them with water, then soak them in 75% medical alcohol for 3-5 minutes, let them dry, and put them in a cleaning box for later use. For electronic thermometers, alcohol cotton balls can be used to wipe and disinfect.
