How to use the mercury thermometer:
? Sterilize the thermometer with 75% alcohol or serum tablets before use and shake the mercury column below 35.5 degrees Celsius.
? The oral thermometer is placed under the tongue of the sick or injured person with the lips closed tightly, and the measurement is taken for three minutes and then removed for direct reading. Oral thermometer can also be used to measure the temperature under the armpit, but the measurement time is five minutes and the reading should be increased by 0.5 degree Celsius.
Note:
? Avoid any factors that may affect the actual body temperature (e.g. drinking boiled water or cold drinks) before taking the temperature.
? The maximum temperature of a glass thermometer is 42 degrees Celsius, so it should not be stored or sterilized above 42 degrees Celsius. Due to the thin glass of the bulb, excessive vibration should be avoided.
? Children should not be used alone for oral thermometry and should be supervised by an adult.
? The thermometer should not be used if it is damaged. The use of broken, should be treated as an emergency, the mercury can not be swallowed, and to be recycled to prevent poisoning and pollution of the environment.
The human body temperature may be below 37 degrees.
Body temperature is the internal temperature of the body. In a normal person, the temperature of the armpit is 30-37 degrees, the temperature of the mouth is 0.2-0.4 degrees higher than that of the armpit, and the temperature of the rectum is 0.3-0.5 degrees higher than that of the mouth.
The temperature of the human body is relatively constant normal human body temperature fluctuates slightly in 24 hours, generally the difference is not more than 1 degree. Under physiological conditions, the body temperature is slightly lower in the morning and slightly higher in the afternoon. Exercise, after eating, women before menstruation or pregnancy body temperature is slightly higher, while the elderly body temperature is low. A higher than normal body temperature is called fever, 37.5-38 degrees for low fever, 38-39 degrees for moderate fever, 39-40 degrees for high fever, and more than 40 degrees for ultra-high fever.
A relatively constant body temperature is one of the most important conditions for maintaining normal life activities, such as body temperature is higher than 41 degrees or lower than 25 degrees will seriously affect the functional activities of the various systems (especially the nervous system), and even jeopardize the life. The body's heat production
and heat dissipation, is regulated by the nerve center, many diseases can make the normal regulation of body temperature dysfunction and make the body temperature
change. Clinically, it is important to check the patient's body temperature and observe its changes in order to diagnose the disease or determine the prognosis of certain diseases.
3. Is there a time limit for using the thermometer?
First of all, we can be sure that the thermometer itself is not the problem, the correct way to use the armpit measurement method is: first of all, the thermometer degree dumped to 35 ℃ below, and then the mercury end of the thermometer placed in the armpit of the most top after the clamping to ensure that the mercury and the skin in close contact with the maintenance of the time of 5 to 10 minutes can be. Due to the physical nature of the mercury, even if it leaves the body, it will not come down, the same reason, continue to clamp it will not rise again.
Secondly, because the human body temperature will produce a gap with the time change, such as the early morning is lower, but in the evening will be slightly higher, or your armpit measurement method is not appropriate, but also may cause errors in your measurement of the data, and the readings of the difference of zero a few degrees is completely normal.
You can change to the oral measurement method again, the method is to first throw the thermometer degree below 35 ℃, sublingual a little hard pressure for 7 minutes. The method is to fling the thermometer below 35℃ and press it under the tongue for 7 minutes.
4. Which electronic thermometer is more accurate?
Agree with the upstairs, I've used two electronic thermometers, both inaccurate, not as good as the simplest kind of mercury. 5. What thermometer should I use to measure my basal body temperature?
How to measure:
It is recommended to use a special basal thermometer, basal thermometer is different from the general thermometer, its scale is more dense, generally 36.7 degrees Celsius (scale 24) for the high and low temperature boundary. (36 degrees - scale 10; 38 degrees - scale 50).
Put the basal thermometer on your pillow at bedtime, and when you wake up the next day, put it under your tongue for five minutes before you get up and move around, and record it on the basal thermometer.
If it is difficult to measure the temperature in the morning, you can do it at a fixed time every day, but remember not to exercise or drink hot or cold food for half an hour beforehand.
The method of measuring basal body temperature is simple but strict and requires long-term persistence. ...... >>
Question 2: How to use an ordinary thermometer under the armpit
Before using the thermometer, shake the mercury mercury column to below 35℃. Place the mercury end of the thermometer at the very top of the armpit (i.e., deep in the armpit), and clamp the thermometer with your upper arm to avoid dislocation or falling; measure for 5-10 minutes; take out the thermometer, read the temperature data, and then wipe the thermometer with a piece of tissue paper for the next time or for someone else to use.
Reading method: Hold the end of the thermometer with one hand, that is, away from the end of the mercury column, so that the eye and the thermometer to maintain the same level, and then slowly rotate the thermometer, from the front to see a very thick column of mercury when you can read out the corresponding temperature value. When reading, be careful not to touch the mercury end of the thermometer with your hand, which will affect the mercury column and cause inaccurate measurements.
Question 3: How to use the electronic thermometer In fact, electronic thermometers are the same way, I use this HRQ-F1 to introduce you to the method of use is very simple, press the ON/OFF button to turn off the thermometer. After power on the digital display detection, and will beep. LCD display as shown in Figure (188.8 indicates normal function, about 2 to 3 seconds after the last recorded temperature display, as shown in Figure (36.8 ° C) indicates that the last time to shut down the temperature value read, about 2 to 3 seconds after the display (L0) and flashing "° C (° F °)" indicates that the temperature can be measured at this point. Place the probe at the temperature to be measured and press it firmly against the skin of the place to be measured, the probe should not be exposed to the air. After about 60 seconds, "°C (°F°)" will stop flashing and the thermometer will emit a reminder sound "Tick-Tick-Tick-Tick" for ten times, and the reading window will show the body temperature detected at this time. temperature, do not turn off the automatic shutdown after ten minutes. The English meaning should be infrared ear thermometer it
Question 4: How to use the thermometer? The thermometer is a maximum thermometer, it can record the highest temperature measured by this thermometer. After using the thermometer should be "back to the table", that is, take the upper part of the thermometer down hard to shake, can make has risen into the tube of mercury, back to the bubble. Other thermometers should never be flung, which is a major difference between thermometers and other liquid thermometers. After the mercury flung back into the tube, you can put in the measurement of the place to start measuring, you are which kind of thermometer on which to measure, there are placed in the armpit under the tongue, etc., and then put a 5 to 10 minutes to take out to look at the glass tube in the mercury column rises to the position (pay attention to see the scale). It is best to disinfect the glass bubble with sterilized cotton before dumping the mercury back into the tube.
Question 5: How to use the thermometer of Tomson BeiJin Electronic thermometer is the use of temperature-sensitive yuan body (usually with thermistor) the size of the resistance value with the change of the ambient temperature of the principle of change made. Electronic thermometer readings intuitive, easy to carry, compact and novel, not easy to damage, easier to keep than ordinary mercury thermometer.
The general electronic thermometer consists of four parts, the head is the temperature-sensitive parts, the pole body is a digital temperature display, next to the power switch button, the end is the battery box and cover. When buying an electronic thermometer, pay attention to the following points:
1, appearance check.
The electronic thermometer is generally made small and beautiful, with a smooth surface and no blemishes.
2. Energized check.
Place the switch in the pass position, see whether the display mark is correct, such as temperature sensing part of the temperature is lower than 34.5 degrees, the LCD screen displays LOC; when the temperature sensing part of the temperature is higher than 42.5 degrees, the LCD screen should show quot;HIC. C mark should stop flashing, and display the number. Disconnect the power supply and then connect, observe whether the same display of the correct mark, if the power supply by a number of on and off test, the correct mark display are the same, and the display of the armpit temperature are consistent, indicating that the repeatability of the electronic body temperature meter is good. If the display is abnormal, it means that the electronic thermometer's battery power is exhausted, or a poor contact somewhere.
3, accuracy check.
Press the switch knob, the LOC mark appears on the LCD display. Put the thermometer under the tongue for 1 minute, when the C mark stops flashing, the displayed reading is the body temperature, which is the oral body temperature. Repeat the measurement a few more times, the oral temperature should be the same, if not the same, the table is not reproducible, can not be selected, and do not need to do the accuracy check, if the oral temperature is exactly the same, then you can carry out the axillary 2-3 minutes of temperature measurement, when the C mark stops blinking the readings that is the axillary * * * temperature. Again, take several more measurements with the same axillary *** temperature value. General oral temperature is about 1 degree higher than the axillary temperature, if the tested oral temperature is too much or too little higher than the axillary temperature, it can be considered that the accuracy of the electronic thermometer is not satisfactory.
4. If the thermometer is placed under the tongue for 1 minute, remove the C mark still continues to flash, it is necessary to disconnect the thermometer's power supply for 5 minutes and then turn on the power to re-measure. Normally, the display will not blink again after the temperature is removed from the mouth. If it still flashes intermittently, the meter must be faulty and cannot be used.
Problem six: axillary *** thermometer how to see the daily morning and evening, various parts of the body and between men and women there are differences in body temperature. Normal body temperature has a more stable range, but not constant. Normal human oral temperature (also known as oral temperature) is 36.2 ℃ ~ 37.2 ℃, the armpit temperature is lower than the oral temperature of 0.2 ℃ ~ 0.5 ℃, rectal temperature (also known as anal temperature) than the oral temperature is higher than the temperature of 0.2 ℃ ~ 0.6 ℃. During the day, 2 to 5 in the morning when the body temperature is the lowest, 5 to 7 in the afternoon when the highest, but the temperature difference within a day should be less than 0.8 ℃. In addition, women's body temperature is generally higher than men's about 0.35 ℃. Women's body temperature during menstruation also has a slight change.
In a healthy state, such as a normal diet, appropriate clothing, the body temperature is generally relatively constant, that is, to remain in the 37 ℃ up and down (roughly between 36.2 ℃ ~ 37.2 ℃), not due to changes in the external environmental temperature and change. The average normal body temperature of the human body is between 36 to 37 ℃ (armpit), beyond this range is fever, 38 ℃ below is low fever, 39 ℃ above is high fever.
Hand holding the thermometer principle mercury column at one end, line of sight to observe the center axis of the glass column, rotate the thermometer, when turned to a certain angle, (should be just at a corner of the triangle.) See the mercury in the glass column and sight perpendicular to the thermometer reading. Each cell of the thermometer represents 0.1 degree Celsius.
Question 7: How to use a thermometer Hello: Thermometers are commonly used medical devices, especially mercury thermometers are most commonly used. With this thermometer to measure body temperature, more than three parts of the human body, but the respective temperatures are also different, anal temperature - the measured body temperature is slightly higher; oral temperature - the middle value; axillary temperature - this belongs to the surface temperature, the temperature of the body. -This is the surface temperature, and the measured temperature reads slightly lower, or 0.2-0.3 handfuls of degrees. If you put the thermometer around your neck, it should also be clipped into a leather fold, with the mercury end not exposed, and in fact a time of 5 minutes or so is sufficient. There is no need to make up the difference in the reading, just say which part of the body temperature measured professionals will understand, you can determine whether there is fever.
Currently there are electronic thermometers that are much more convenient.
Question 8: How to use a thermometer correctly? Measuring body temperature is an important way to identify healthy people and "SARS" patients, suspected patients. At present, there are many types of thermometers on the market, and there are big differences in performance and usage. In this regard, the Beijing Municipal Institute of Metrology experts to remind consumers according to their own characteristics, the correct choice and use of thermometers.
According to measurement experts, the most common thermometer is a glass thermometer, which can be made with the body temperature of the mercury column to maintain the original position, so that the user to observe at any time. Due to the structure of the glass is relatively dense, the performance of the mercury is very stable, so the glass thermometer has the value of accurate, high stability features, there are inexpensive, without the advantages of external power supply, by the people, especially the trust of medical workers. But the defects of the glass thermometer is also relatively obvious, easy to break, there is the possibility of mercury contamination; measurement time is relatively long, the use of emergency patients, the elderly, infants and young children is inconvenient, reading is more laborious.
With the development of science and technology, there are many types of new thermometers. Electronic thermometers use the physical parameters of certain substances (such as resistance, voltage, current, etc.) and the ambient temperature of the relationship between the existence of the determination of the body temperature in the form of digital display, clear readings, easy to carry. Its shortcoming is that the accuracy of the display value is affected by the electronic components and battery power supply and other factors, not as good as the glass thermometer.
Thermometers are generally used in the armpits, mouth, rectum, etc. In practice, people generally feel inconvenient or uncomfortable. The ear thermometer is a non-contact measurement of the body temperature through the measurement of the radiant brightness of the tympanic membrane of the ear. Just point the probe to the inner ear canal, press the measurement button, only a few seconds to get the measurement data, very suitable for patients with acute and serious diseases, the elderly, infants and young children. However, at the initial stage of use, the user may get several different measurements due to unfamiliarity with this mode of operation, but generally speaking, the maximum value of the actual measurement is the desired data. Users will be more satisfied with this thermometer after familiarizing themselves with it.
The continuous development of new technologies has brought a very peculiar thermometer, can be called a piece of thermometer or dot matrix thermometer. This thermometer is only the size of a business card, 6-7 centimeters long, 0.5 centimeters wide or so, covered with a number of numbers with a neatly arranged dots. In the body temperature test, a certain value below the dots will all darken, while the rest of the dots color unchanged, the user can determine the body temperature according to the above changes. This thermometer is inexpensive, small in size, easy to carry and store, and very little pollution itself, especially for medical institutions, can be used once to avoid cross-infection.
Experts said that the glass thermometer belongs to the national mandatory verification of measuring instruments, and production and use of a long history, both in product quality or in supervision and management is basically more standardized. However, many digital thermometers, ear thermometers used to be the image of health care products and gifts in the market, has not been subject to the relevant state departments of supervision and management of strict and effective.
Experts reminded that if consumers want to choose digital, ear thermometers for temperature measurement, should pay attention to the following aspects: First, due to the temperature test requirements are more stringent, the general requirements of the thermometer's display error of ± 0.1 degrees Celsius, the accuracy of the consumer's purchase of thermometers must meet this requirement. Second, carefully read the instruction manual, pay attention to the operating points. In the beginning of the use of glass thermometer can be compared with the use to determine whether the use of the correct way. Third, when using underarm measurement, must be clamped to ensure that the thermometer and the body full contact. When using oral measurement, the thermometer must be placed under the tongue, slightly pressed, and must be cleaned and sterilized after measurement. Fourth, no matter which kind of thermometer is chosen, it is best to have one for each person to avoid cross-infection.
1, the use of underarm measurement
Before using the thermometer degree dumped below 35 ℃, and then the mercury end of the thermometer placed in the armpit at the top of the clamp, to ensure that the mercury and the skin in close contact with the maintenance of the time 5 ~ 10 minutes. Remove the thermometer, take a reading and wipe it clean with toilet paper for next use. It should be emphasized that the armpits, if there is sweat, should be wiped clean before measurement, while drinking a hot drink, after strenuous exercise or after bathing to be quiet for 30 minutes before measurement, in addition to the armpits measurement if the time is not up to the child to release, the need to re-measurement, the time should also be recalculated.
2, the use of oral measurement
More than the armpit can reflect the body's true temperature, but this method for children there is a risk of biting through the mercury, fever, breathing difficulties, unconscious patients should not use.
