The mercury thermometer can t understand how many degrees, how to see how many degrees the mercury t

Pinch the thermometer in one hand and spin it to look.

Armpit temperature, normal.

It has a marker that is easy to see. That's 37 degrees.

When looking at the mercury thermometer, the back of the mercury column is best to be white, so that it is easy to see the height of the mercury. If it is a thermometer, then you can only slowly adjust the angle of the thermometer to maximize the scale magnification.

The degree of the thermometer is from 35 degrees to 42 degrees, and there are 14 large grids on the scale, one large grid represents the degree, and one large grid is divided into five small grids, each small grid represents the degree.

Before measuring the body temperature, it is necessary to forcefully throw the mercury back into the ball of the thermometer to avoid errors after the measurement. The oral or anal temperature is measured for 3-5 minutes, and the axillary temperature takes about 10 minutes before the reading is taken.

Mercury thermometer is mainly composed of mercury head and glass tube, mostly in the form of a prism, when the patient sees the mercury line, there should be a ridge facing the line of sight, which can be used as a standard to find the mercury line. When reading, you should pinch the tail of the thermometer, place the thermometer parallel to the line of sight, or slightly higher than the level of the eye line, and rotate slowly in a bright place, you can see a red or silver mercury column, when observing the thermometer power, you should pay attention to the mercury head to the left, the glass tube to the right, the scale to face up, and the value to face down, and the value is the accurate body temperature.

When measuring body temperature with mercury temperature, it is necessary to throw the mercury column below 35 before continuing to measure the body temperature, otherwise the measured value may not be accurate, because the mercury thermometer mainly achieves the purpose of temperature measurement through the principle of thermal expansion and cold contraction, and the mercury column inside will rise with the increase of body temperature, but will not drop with the body temperature, so it will be accurate to measure accurately when thrown to a low temperature before measurement. The specific steps are as follows:

1. After the mercury thermometer is measured, it is necessary to take a reading, and hold the tail end of the thermometer with the hand of the world stove when reading, and be careful not to touch the mercury end with your hand to avoid errors.

2. When reading, the eye and the thermometer measure are level up, pay attention to the mercury head to the left, the glass tube to the right, the scale to face up, and the value to face down, so that the reading value is accurate.

3. When reading, the eye and the thermometer measure are level up, pay attention to the mercury head to the left, the glass tube to the right, the scale to face up, and the value to face down, so that the read value is accurate.

4. The value read out is between 36 and 37 for normal body temperature, and the value indicates fever, and between it is low-grade fever, which is high and cracked fever, and fever is needed.

Mercury thermometer (mercury tube is columnar), it is best to disinfect with 75 alcohol before use, and then pinch the upper end of the thermometer with your fingers and shake it down (to the side of the mercury ball) after disinfection, so that the mercury column is thrown below 35, and then put the thermometer under the patient's tongue, and the lips are closed for about 3 minutes before taking it out. After taking out, tilt one end of the mercury ball slightly downward to avoid vibration, and the triangular prism is in line of sight, and turn it slightly forward and backward, the mercury column is clearly visible, and the reading can be done.

In daily life, when people are sick and have a fever, they will use a thermometer to measure their body temperature, and a mercury thermometer is a commonly used thermometer.

01 Disinfect the thermometer with 75 alcohol, and then pinch the upper end of the thermometer with your fingers and shake it down (to the side of the mercury ball) to throw the mercury column below 35.

02 Put the thermometer in your mouth or armpit, close your mouth or armpit tightly for about 5 minutes, and then take it out.

03 According to the scale of the actual display of mercury, read the data, there are ten cells between every two numbers, each small cell represents degrees, ** is displayed as degrees.

04 After the mercury thermometer is used, wipe it with alcohol, on the one hand, it can be disinfected, on the other hand, alcohol is volatile, and the problem of mercury column can be lowered, and then it is stored in plastic packaging.

Kiss, I'm sorry to keep you waiting, I'll help you with this question. The opinion of the mercury thermometer is as follows: 1. The thermometer reading is exceeded:

It indicates that the body temperature has increased, and it is necessary to actively find the cause of the increase in body temperature, and treat the corresponding cause accordingly to improve the patient's symptoms. 2. The thermometer reads the imitation liter number under the bright light: it means that the body temperature of the hidden width is too low or the measurement is inaccurate, and it needs to be confirmed by repeated measurements.

Before measuring the temperature with a mercury thermometer, the scale of the mercury thermometer should be shaken below 35, and the armpit should be dried before measuring, and the measurement should be held for 5-10 minutes.

The mercury thermometer is divided into the mercury head and the whole thermometer measurement part, you can put the top of the mercury head under the armpit or the bottom of the mouth during the test, take out the thermometer after 5-10 minutes of testing, do not hold the mercury end, touch it by observing the scale and read out the size of the front and the sun, starting from 35, 42 as the end.

Generally speaking, the temperature of the mercury is where it goes, and if it is, you can see that there are 7 small cells after 36. The method of reading the mercury thermometer can be mastered after two checks or two readings, which is a relatively simple method.

Mercury thermometer is a kind of expansion thermometer, the freezing point of mercury is -39, the boiling point is silver chain, and the measurement temperature range is -39 °C - 357 °C, it can only be used as a gauge for local supervision. It is not only simple and intuitive to measure temperature, but also avoids errors with external remote thermometers.

If you hold the triangular shape of the thermometer horizontally and move it horizontally to the eye and slowly rotate it to see if there is a small thin line inside, it will show how many degrees.

When you look at it, put the thermometer that has been measured for 5 minutes flat in front of your eyes, and see that the scale of the mercury column points to several large scales, 35-39, and there are 10 units with millimeters as the dividing line in the middle, for example, it belongs to low fever, which belongs to normal body temperature, and higher than 39-40 belongs to high fever and ultra-high fever.

There are three ways to use a mercury thermometer, the most commonly used is to measure the temperature under the armpits, but also to measure the temperature in the mouth and in the rectum. Rectal temperature measurement is mainly used for uncooperative infants and young children, who sweat a lot under their armpits, are not clamped tightly, and do not cooperate, which can easily lead to body temperature distortion. The temperature measurement in the oral cavity is worried about poisoning after the mercury breaks, so the most commonly used is the intraanal temperature measurement.

When reading the value, load it in the direction of the maximum tangent of the convex meniscus with your eyes fixed.

Hold the tail end of the electronic thermometer in one hand, that is, avoid the end of the mercury column, so that the eye and the electronic thermometer are maintained at the same level, and then gradually rotate the electronic thermometer, and when you see the mercury column that is too thick from the face, you can read the corresponding degree value, and look at the three-edged area in the middle of the ruler and the data; The triangular area has a bigger effect. Two fingers pinched the top of the electronic thermometer and shook it gently, and a wire was seen.

When reading the value, pay attention not to touch the liquid mercury end of the electronic thermometer, otherwise it will be dangerous to bend the mercury column and cause accurate measurement to be prohibited, and the mercury thermometer should be vertical or skewed with the fluidity orientation of the measured steam parameters.

Mercury thermometer to see the temperature method: clamp the mercury end of the thermometer under the armpit to measure, wait for 10 minutes and then take it out, turn the thermometer until you see the red line in the middle of the thermometer, the top of the red line corresponds to the temperature on the right side of what degrees, then the measured temperature is how many degrees. Compared with mercury thermometers, mercury thermometers have higher accuracy and a wider measurement rangeBut the disadvantage is that it is very harmful to break it.

Red water thermometer is mainly divided into alcohol thermometer and kerosene thermometer, alcohol thermometer is a thermometer made by using the properties of thermal expansion and contraction, the boiling point of alcohol is 78, and the highest temperature that can be measured is 78. As for the working substance of the kerosene thermometer is kerosene, its boiling point is higher than 150, and the measurement temperature range is -30 -150, so the alcohol thermometer is better than the kerosene thermometer to test the high and low temperature, but the alcohol thermometer is higher than 78 can not continue to measure, and the kerosene thermometer can, but it cannot be used as an accurate measurement.

The measurement range of mercury thermometer is -39 °C - 357 °C, which is higher than the measurement range of alcohol thermometer and kerosene thermometer, and the accuracy is also Mercury temperature is higher than that of red water thermometer, and the mercury thermometer is also relatively cheap. However, the disadvantage of mercury thermometer is also relatively obvious, that is, it will be harmful to heavy metals if broken. However, as long as you master the correct use of the mercury, it will not have any effect on the shipment to avoid the mercury breakage.

Moreover, when measuring body temperature, no matter what kind of thermometer is used incorrectly, the test results will be inaccurate.

How to see the mercury thermometer degree:

1. The thermometer is a Mitsubishi structure, with contents on three sides, one side is marked with the production date and brand of the thermometer, one side is marked with the temperature degree, and the other side is marked with a scale.

2. The degree of the thermometer is from 35 degrees to 42 degrees, and the scale is divided into 14 large grids, each large grid represents the degree, and each small grid represents the degree.

3. After holding the thermometer in your hand, pinch the tail of the thermometer with your hand and turn the thermometer to the middle of the degree and scale.

4. Turn the thermometer to the middle of the degree and the scale, you will see a silver line, if you don't see it, turn it up and down and look for a while to see it.

5. When you want to test the body temperature of a person, hold the tail of the thermometer, gently shake the thermometer, let the silver line of the thermometer scale drop below 35 degrees, and then clamp the thermometer (silver place) to the armpit, and take it out after 10 15 minutes.

6. When the time is up, take out the thermometer from under the armpit, and follow the gap between the two sides of the scale and the degree to see the position of the silver line rising. Read the number next to the silver line is the degree, and you can see that the current thermometer is the degree.
