How long does the mercury temperature measure and how long does the mercury thermometer take

There are three ways to measure body temperature with a mercury thermometer, which can be taken by oral, anal, and axillary measurements, each of which is different and has a different normal temperature value. The normal value of the oral test is that the mouth test should not drink hot water, boiled water or ice water for 10 minutes before the measurement, and it should not be used for infants and people who are delirious. The normal value of anal measurement is that anal measurement is generally higher than oral measurement, and is mostly used in children, delirium, and some special conditions.

The normal value of axillary measurement is 36-37, and the axillary measurement should be paid attention to wipe the armpit clean before measurement, so as not to affect the examination results. In addition, be sure to leave it for 10 minutes, and then read the value, the temperature of the armpit is lower than the mouth temperature, and the axillary temperature is a common way to measure.

Measure 5-10 min. The measurement time is the same.

1. Armpit temperature:

The mercury column and mercury column of the thermometer should be lowered below 35 before use. Place the mercury end of the thermometer on top of the armpit (i.e., axillary depth) and clamp the thermometer with your upper arm to avoid misalignment or falling; Measure 5-10 min. Take out the thermometer, read the temperature data, and wipe the thermometer with toilet paper for next use or other use.

2. Oral temperature measurement:

Oral temperature collection is based on the patient's ability to properly and safely place the thermometer into the mouth. That is, children or people who are not resistant to coughing, weakness or vomiting are excluded (this is not a problem with fast-acting electronic thermometers, but it is an important subject in mercury thermometers, since the reaction to temperature takes a long time).

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 is to hold the tail end of the thermometer in one hand, that is, the end of the mercury column away from the seller, so that the eyes and the thermometer are kept at the same level, and then slowly turn the thermometer, and 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.

Details:Mercury thermometer measures the body surface temperature mostly to measure the armpit temperature, the method is to put the mercury thermometer with mercury into the armpit auspicious code clamping, generally the mercury thermometer time to 5 10 minutes, if the clamp time is too short, the mercury is not fully heated, 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.

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.
