Mercury thermometers are measured for a few minutes, and mercury thermometers are measured for sever

A mercury thermometer is generally fine for five minutes.

Before using the mercury thermometer, you need to throw the mercury mercury below 35, and then put the mercury end of the thermometer on the top of the armpit, which is deep in the armpit, and clamp the thermometer with the upper arm to avoid dislocation and falling. After five minutes of measurement, take out the thermometer, read the temperature data, and wipe it with toilet paper for next use or someone else.

The method of reading, hold the tail end of the thermometer with one hand, that is, the end away from the mercury column, so that the eyes and the thermometer are kept at the same level, and then slowly turn the thermometer, when you see a very thick mercury column from the front, you can read the corresponding temperature value. When reading, do not touch the water temperature end of the thermometer with your hands, as this will affect the mercury column and cause inaccurate measurement.

Measuring body temperature with a mercury thermometer generally takes 5-10 minutes.

Mercury thermometer measures body surface temperature mostly to measure armpit temperature, the method is to put the mercury thermometer with mercury into the armpit clamping, generally the mercury thermometer time to 5 10 minutes, if the clamp time is too short, the mercury is not fully heated, and the measured temperature is biased. Mercury thermometers measure body temperature more accurately than forehead thermometers because their measurements are less disturbed.

Measure the mercury under the armpit thermometer: generally 5 to 10 minutes, preferably full 10 minutes.

Measure oral mercury thermometer: generally 3 to 5 minutes, preferably full 5 minutes.

Measure rectal mercury thermometer: generally 1 to 3 minutes, preferably full 3 minutes.

The measurement of mercury thermometer must be thrown to 35 before the measurement, and before the measurement, do not drink hot water or exercise vigorously, so as not to affect the final measurement result.

For the regular use of mercury thermometers, be sure to remember to wipe and disinfect with alcohol to avoid bacterial infection. In addition, the mercury thermometer must be used carefully, the mercury is toxic, broken, must be dealt with in time, immediately open the window for ventilation, can not be directly touched by hand, can not be dragged with a mop, to be collected with cardboard and sealed for special treatment.

It usually takes 3-10 minutes to measure body temperature with a mercury thermometer.

A mercury thermometer is a type of thermometer in which it is made of glass and contains a column of mercury that rises as the body temperature rises.

The measurement time of the mercury thermometer needs to be judged according to the measurement site, if the patient is measuring the armpit area, it is generally measured for 5-10 minutes. If the measurement is done in the oral cavity, it is usually measured for 3-5 minutes. In some patients, the rectum can also be measured, usually for about 3 minutes.

Normally, the normal value of armpit temperature is, the oral temperature is, and the rectocerebral intestinal temperature is. If the measured value is beyond the normal range, it is usually considered to be a fever.

If the patient has a fever, he or she needs to go to a regular hospital for relevant examinations based on his own condition, so as to be clear. Once diagnosed, it is necessary to actively cooperate with the doctor to take relevant measures.

How the mercury thermometer works:

The working substance of the thermometer is mercury. Its glass bubble volume is much larger than that of the thin tube above. Due to the influence of body temperature, the mercury in the bubble produces slight changes, and the expansion of the mercury volume causes a significant change in the length of the mercury column in the tube.

The temperature of the human body varies between 35 and 42, so the scale of the thermometer is 35 to 42, and the range of each degree is divided into 10 parts, so the thermometer can be accurate to 1 10 degrees. When reading, take it out of the armpit or mouth, at which point the temperature of the glass bubble beneath it will decrease.

In order for his readings to still be representative of body temperature, a special design had to be made, which was a very thin tube between the glass bubble and the straight glass tube, the neck.

The lower part of the thermometer is close to the neck of the vacuole is a very narrow curved neck, when the body temperature is measured, the mercury in the glass bubble expands with the increase of temperature, squeezes through the thin tube to the straight tube, rises from the neck part to a certain position in the tube, and when the thermal equilibrium with the body temperature is reached, the mercury column is constant.

When the outside temperature is low, the volume of mercury shrinks when it is cold, and it is partially disconnected in the narrow curved neck cavity, so that the mercury in the thin tube cannot be returned to the glass bubble, and the height reached by the mercury column when it is in contact with the human body is still maintained, so it still represents the temperature of the human body when it leaves the body.

After use, the thermometer should be "returned to the table", that is, the upper part of the thermometer should be thrown down forcefully, so that the mercury that has risen into the tube can be returned to the glass bubble. Other thermometers should never be shaken, which is a major difference between thermometers and other liquid thermometers.

5 minutes is close to the actual temperature of body temperature, and 10 minutes, the energy of the body's pulsation will be superimposed, which will increase the error of measurement, resulting in the difference between the reading of 5 minutes and 10 minutes, so the body temperature will be measured for 5 minutes. The body temperature of the human body can be dialed within 1 day, and the body temperature will be different at different times, as long as the body does not feel abnormal, it is fine.

A mercury thermometer, a type of thermometer, is made of glass with a column of mercury that rises with body temperature. Mercury thermometers are widely used in the medical field and in ordinary households, and mercury thermometers are available in some pharmacies.

Mercury thermometers are also known as "medical thermometers". The working substance of the thermometer is mercury, and its vacuole volume is much larger than the volume of the thin tube above, and the mercury in the vacuole expands due to the influence of body temperature, which will make the length of the mercury column in the tube change significantly.

The change in human body temperature is generally between 35 and 42, so the scale of the thermometer is usually 35 to 42, and the range of each degree is divided into 10 parts, so the thermometer can be accurate to 1 10 degrees.

After use, the thermometer should be "returned to the table", that is, the upper part of the thermometer should be thrown down violently, so that the mercury that has risen into the tube will return to the vacuole; Other thermometers cannot be shaken, which is a major difference between thermometers and other liquid thermometers.
