What are the correct ways to use the thermometer?Cold fever is an unavoidable experience in life. In family life, ordinary cold fever rarely goes to the hospital. Basically, the family will prepare a thermometer.The thermometer can measure the highest temperature of the body, indicating the health of the human body.So what is the correct way to eat body thermometer?How many types of thermometers are?What are the structural characteristics of the thermometer?How long is the heating of the thermometer?
Thermometer of the thermometer
What is the barrier of the thermometer?The thermometer uses the working principle of heat -up and contraction. Its structure is composed of a scaling vacuum capsule, and the end of the ball is full of mercury.When measuring the body temperature, the bottom of the bottom of the mercury is heating and expanding, rising along the capillary tube, the height is directly proportional to the heating level. The higher the surface temperature, the higher the mercury column rises.There is a narrow part where the balls of the body thermometer are connected to the capillary tube to prevent mercury from falling on its own to view the temperature. The mercury column must be reduced to the original value after shocking.
The range of the thermometer is generally 35 ° -42 ° Celsius, and the points value is 0.1 °.
The thermometer looks like a small glass stick, but there are still a lot of attention when using it. If you dont pay attention to it, it will cause the results to be inaccurate.
Mercury thermometers are more stable compared to other types of thermometers, and do not need to be connected to the power supply, and the price is low. Each family can buy a convenient daily life, but the mercury thermometer is easy to break, and it needs to wait for a while to measure. NoLike the general electronic thermometer, the temperature of the measurement object is displayed directly with numbers, which is clear at a glance.
When using a mercury body thermometer, hold the tail of the thermometer of the mercury in one hand, that is, far from the end of the mercury column, keep the eyes and the thermometer of the same level, and then slowly turn the thermometer, and see the thick mercury column from the front (the red red in the middle)You can read the corresponding temperature value.When reading, pay attention not to use the mercury end of the temperature meter with your hands, which will affect the measurement of the water column and cause the measurement.
Structural characteristics of the thermometer
What are the structural characteristics of the thermometer?The thermometer is a tool to measure the temperature of the human body, and it is also the most common thermometer.It is one of the very useful medical tools by measuring the temperature of the human body and reading the value to read the value of the human body.What are the structural characteristics of the thermometer?How much do you know about the thermometer of mercury?
The common thermometer in the family is mercury thermometer, which uses the principle of heat -up and contraction to work.The structural characteristics of mercury thermometer are mainly manifested in five aspects:
1. Can be separated from the number of tested objects
2. More mercury containing
3. There are shrinkage
4. The points value is 0.1 ℃
5. The inner and thin and long pipe diameter
6. Fragile items
According to metering experts, the most common thermometer is vitrus thermometer. It can keep the original location of the mercury pillar with the height of the body, which is convenient for users to observe at any time.Because the structure of the glass is relatively dense and the performance of mercury is very stable, the vitrus thermometer has the characteristics of accurate display value and high stability, as well as the advantages of low price and no external power supply, which is deeply trusted by people, especially medical workers.However, the shortcomings of the vitrus thermometer are also relatively obvious, crushed, and the possibility of mercury pollution; the measurement time is relatively long, which is inconvenient to use it for patients with severe diseases, elderly people, infants and young children, and the reading is more troublesome.
Types of thermometer
How many types of thermometers are?The thermometer is a type of thermometer. It is a medical appliance used to measure the highest body temperature of the human body.In addition to the use of hospital clinics, a body thermometer is often prepared in the family.The initial thermometer was mercury thermometer. Later, with the progress of the times and the development of technology, more and more families began to use electronic thermometers.The type of thermometer has increased, and the general use of thermometers also shows that the improvement of peoples medical awareness.How many types of thermometers are there?Lets take a look together.
The more common thermometers on the market are glass mercury thermometers, electronic thermometers, and multi -functional infrared thermometers.
1. Glass mercury thermometer
The thermometer of the mercury is a traditional thermometer, which is made of glass, and there is a mercury column that continues to rise with the body temperature.Mercury thermometer has the characteristics of accurate measurement results, high stability, and low price.Mercury thermometer contains mercury, and mercury has a greater harm to human body. Once mercury vapor is inhaled, it will enter the human organ tissue through blood circulation. It can also damage the central nervous system of the people through the blood -brain barrier.After entering the water body into the water body, it is converted into methyl mercury, especially for the harm to developing fetuses and infants.And methyl mercury is also enriched with the food chain in animals and human body, threatening our health.Considering mercury hazards of mercury body thermometers, many countries have taken prohibition measures.
2. Electronic thermometer
The thermometer of the electronic body uses the physical parameters of certain substances, such as resistance, voltage, current, etc., and the determined relationship with the environmental temperature is displayed in the form of numbers.Electronic thermometers are convenient, short -measurement, and no mercury, which is harmless to the human body and the surrounding environment.The deficiencies are that the accuracy of the value is affected by factors such as electronic components and battery power supply.
3. Multifunctional infrared thermometer
Infrared thermometers are measured by infrared body temperature. Compared with electronic thermometers, the measurement speed is faster and shorter than the electronic thermometer. It can be divided into two types: contact and non -contact.In contact -type infrared thermometers, there are ear thermometers, forehead thermometers, and multi -functional thermometers. As long as one second, you can measure accurate body temperature from the ear.Non -contact infrared thermometer is the most common temperature gun, which can measure the temperature of the human body.Just aim at the forehead and press the measurement button. The measurement data can be obtained in just a few seconds. It is very suitable for patients with acute diseases, elderly people, infants, etc.However, in the early days of use, because users are not familiar with this operation, they may get several different measurement data. Generally speaking, the maximum value is the data.When users are familiar with, they will be more satisfied with this thermometer.Considering the harm of mercury, more and more families begin to use faster and safe thermometers.
How to use the thermometer
What are the correct ways to use the thermometer?The thermometer is a necessary medical tool for family life.From the traditional mercury body thermometer to the increasingly common electronic thermometer and infrared thermometer, the thermometer can be described as more and more technological and high -end.For different types of body thermometers, the method of use is different.Do you know the correct way to use the thermometer?What problems should we pay special attention to in the process of using the thermometer?
The most thermometer type we use in daily life is the thermometer.There are three main methods for measuring body temperature with mercury thermometers, namely mouth temperature, armpit temperature and anal temperature.The measurement method of each part has its own suitable crowd, limitations, and precautions for use. The following is a specific way to see the correct use method of the thermometer measurement.
1. The correct method of use of thermometer -Use mercury thermometer to measure the mouth temperature:
(1) Throw the thermometer to below 35 ° C before use.
(2) Place the thermometer under the tongue (just hold it, do not bite and speak hard).
(3) At least 3-5 minutes, the best 7 minutes.
(4) Take out the thermometer, read the temperature data, wipe it clean with toilet paper, and then disinfect it with alcohol cotton slices (wiped from the tail end to the mercury end).
Kind tips:
(1) Infants and young children, dyspnea, unclear consciousness, history of spasm, and those who cannot collaborate, please do not measure your mouth temperature.
(2) Do not eat and exercise strenuous exercise within 30 minutes.
2. The correct method of use of thermometer -Use mercury thermometer to measure the armpit temperature:
(1) Put the temperature meter below 35 ° C before use.
(2) Do not take a bath before measuring. Wipe off the sweat of the armpit first, and clamp the mercury end of the body temperature meter in the middle of the armpit. Be careful not to extend the head to the outside. If it is a child, pay attention to support his arm to prevent movement.
(4) Take out the thermometer and read the temperature data, wipe the thermometer with a toilet paper.
Kind tips:
(1) If the time is left or if you accidentally move it, you need to be re -measured, and the time needs to be re -calculated.
(2) Drinking hot drinks, strenuous exercise, emotional excitement, and bathing need to be measured after 30 minutes.
3. The correct method of use of thermometer — Use mercury thermometer to measure anal temperature:
(1) Baby adopt a lie on the legs or lying posture, and children and adults are lying on the side.
(2) Put the temperature meter below 35 ° C before use.Lubricate the mercury end of the anal table with lubricant (Vaselin or Paraffin Oil).
(3) Open the anus in the hand, rotate the anus surface and slowly insert it. The hands of the anal watch are fixed at the same time to prevent slipping or inserting too deep.
(4) Inserting depth: baby 1.25 cm; child 2.5 cm; adult 3.5 cm
(6) Take out the anal table, read the temperature number, wipe it clean with toilet paper, and then disinfect it with alcohol cotton slices (wipe from the tail end to the mercury end).
Kind tips:
(1) Diarrhea and rectal diseases, and surgery prohibit anal temperature.
(2) Drinking hot drinks, strenuous exercise, emotional excitement, and bathing need to be measured after 30 minutes.
(3) The anal temperature is closest to the temperature of the human body, and it is minimized due to the ambient temperature, but it is not convenient to measure and is not suitable for screening.Therefore, this method can only be used on the basis of confirmation of other measurement methods.
(4) Wipe the thermometer of the body with a toilet paper, and then read the temperature data.
In fact, the mouth temperature and anal temperature are closer to the temperature of the human body, but these have certain restrictions on these. For example, babies and children who are growing teeth are not suitable for measuring mouth temperature with body temperature.Suitable for anal temperature.
