How to use a mask correctly?
1、Pay attention to the front and back of the mask
First of all, when we wear a mask, we need to pay attention to the front and back of the mask. When we wear it, don't wear it upside down, otherwise it won't be able to filter viruses.
2、Do not touch the outside of the mask with your hand
After you wear the mask, be careful not to touch the outside of the mask with your hand, otherwise your hands will touch the external filtered virus.
3、Do not recycle disposable masks
If the mask we buy is a disposable mask, please do not recycle it, because after using it once, the mask can no longer be used for filtering viruses.
4、Pay attention to discarding masks
When we are finished using the masks, we must pay attention during the process of discarding, do not discard randomly, and must be discarded to the designated trash can, so as not to increase the risk of virus infection.
5.Purchase of masks

6.Hold the metal bar of the bridge of the nose
When you wear a mask, you must use both hands to hold the metal strip of the bridge of the nose, so that the mask is close to the nose and mouth, so that it can work.
How to distinguish between genuine and fake 3M masks
Since most of the 3M masks we buy are in bulk, it is difficult to check the authenticity of the mask through the box, so we need to observe carefully at this time.
1.Smell the smell, 3M masks do not have any odor, only activated carbon masks have a faint smell of activated carbon, and the rubber bands have no taste.
2.Looking at the logo, the 3M logo is quite different. The real 3M mask font is closer, but the fake looks looser, and you can pull it out by hand.
3.Looking at printing, 3M masks are all printed by laser, and the print marks are at a 45-degree oblique angle, while fakes are printed with ink, and often have uneven ink marks, and the ink dots are round.
4.Identifying the LA mark and QS certification, as long as it is imported formally, it must have QS and LA certification.
How to distinguish between genuine and fake disposable medical masks?
1.Mask appearance
Regular medical masks are composed of inner, middle and outer layers. The inner layer is skin-friendly, the middle layer is an isolation filter layer, and the outer layer is a special material antibacterial layer. When you get a mask, you can tell the first few layers. If it is two or one layer, don't buy it. Especially in the special period now, when you buy fake masks, you can't isolate them.
2.Online Enquiry
According to the product registration number or record number on the outer packaging of the medical mask, select the corresponding medical device product (registration or record), and then enter the registration number or record number according to the selected registration or record, because some manufacturers produce products that are Some registration numbers are record numbers.
Which masks cannot be reused
1.It is not necessary to change one at a time without directly contacting the suspected patient. Normal masks can be reused 5 times within 2 days as long as they are kept.
2.After wearing the mask and taking it off, check whether the mask is deformed and damaged. If it is deformed, it cannot be used again. It can be stored in a dry and ventilated place without deformation.
3.Inspect yourself for colds, fever, and other symptoms. If such a mask is not reusable, you need to wear a new one.
4If it is some more dangerous public area, such as local hospitals, pharmacies, etc., then the used masks should not be reused.

Types of thermometers and buying guide
1.glass-stem thermometer
The most accurate thermometer at present. It has the advantages of accurate indication, high stability and low price. However, it is easy to break, and there is a possibility of mercury pollution; the measurement time is relatively long and the reading is inconvenient, and it is not convenient for groups such as patients with severe illness, the elderly, infants and young children.
2.Electronic thermometer
It has the advantages of clear reading, convenient carrying, high accuracy and small error. However, its accuracy is affected by factors such as the power supply of electronic components and batteries, and is not as stable as a glass thermometer.
3.Infrared thermometer
The body temperature is measured by infrared rays, which can be divided into two types: contact type and non-contact type. It has the advantages of safety, accuracy, and short measurement time, but repeated measurements may have some errors.
Buying points and recommendations for thermometer
1.Glass thermometers are relatively inexpensive. However, it is not convenient to use, especially the possibility of mercury pollution, so it is not recommended for families with small children. However, it is recommended to use a glass thermometer for adult fever measurement.
According to different measurement locations, vitreous thermometers can be divided into three types: mouth thermometer (round body with thin head), anal thermometer (round body with thick head), and axillary thermometer (flat body with thin head). The average mouth temperature was 37 ° C. The measurement time is usually about 3-5 minutes. The normal mouth temperature is 36.2 ℃ -37.3 ℃. The body temperature measured by the anal temperature is more reliable. The average value is 36.3 ℃ -37.5 ℃. It only takes 3 minutes. The normal value of the axillary temperature is 36 ℃ -37 ℃, the measurement time generally takes 7-10 minutes.
2.Electronic thermometers are more expensive than glass thermometers, typically ranging from tens to hundreds of yuan. Infants and young children are advised to use electronic thermometers.
Electronic thermometers can be divided into hard rod type, soft rod type, and pacifier type. Rigid rod type is generally suitable for families, using axillary and oral measurement methods. The soft rod type is a soft-head electronic thermometer. The front end can be arbitrarily bent, multi-directional, and has no dead angles. It is suitable for measurement of various parts. Generally, three measurement methods of oral cavity, underarm and anus can be used. The pacifier type is mostly a baby pacifier, which is carefully designed according to the physiological characteristics of infants and young children.
The measurement time and temperature vary depending on the measurement location. Oral fever temperature is above 37.5 ℃, measurement time is 3-5 minutes; rectal (anal) fever temperature is above 38 ℃, measurement time is 1-3 minutes; axillary fever temperature is above 37 ℃, measurement time is 5-10 minutes .
3.Infrared thermometers generally have prices ranging from tens to hundreds of yuan. Common contact infrared thermometers include ear thermometers, whose normal readings are 35.5 ° C-37.8 ° C. As long as 1 second, accurate body temperature can be measured from the ear, which is especially suitable for re-examination of patients with continuous fever. The most common non-contact infrared thermometer is a forehead gun. Its normal reading is about 36.0 ℃ -37.0 ℃, and the measurement data can be obtained in just a few seconds. It is very suitable for patients with severe illness, the elderly, infants and young children.
Types of hand sanitizer and buying guide
1. Hand Sanitizer
It mainly plays the role of cleaning and decontamination, but does not claim to have bactericidal or bacteriostatic effects. The current product standards are: GB / T 34855-2017 "Hand Sanitizer" and QB / T 2654-2013 "Hand Sanitizer".
2. Special Hand Sanitizer
In other words, in addition to surfactants, antibacterial or bacteriostatic ingredients are added to the formula in addition to the surfactant, which can decontaminate and clean, and can also kill bacteria or inhibit the growth of bacteria. The current product standards are: GB 19877.1-2005 "Special Hand Wash".
3.General Disposable Hand Sanitizer
There is no need to wash after use. Disposable hand sanitizers generally follow corporate standards.
4. Disposable hand sanitizer
It means that the active ingredients and skin care ingredients are added to the product. After using the product to kill the pathogenic bacteria on the hands, do not wash it with water. As it is a hand disinfection product, the product should meet GB27950-2011 "Hand Sanitizer Hygiene Requirements".
Precautions for use
1. Remember to wash your hands before meals, after urinating, going home, touching garbage, and touching animals. When washing your hands, pay attention to washing with running water and hand sanitizer, rubbing for at least 20 seconds.
2. In general, ordinary hand sanitizers and antibacterial antibacterial hand sanitizers have been able to meet the daily cleaning needs of ordinary citizens' hands.
3. It is not recommended to use a disposable hand sanitizer as a regular hand cleaning method, and try to use it only when there is no water.
4. In some public places, the hand sanitizer is diluted after being used in order to save costs. In this way, both the sterilization ability and the cleaning ability are greatly reduced.
Can goggles resist virus invasion?
In the past, it was thought that the disease could only be infected by droplets. In fact, the mouth, nose and eyes may come into contact with the virus. Generally, doctors will wear goggles themselves when they are performing high-risk diagnosis and treatment.
Including N95 masks, goggles, and protective clothing are all ways for medical personnel to protect themselves against new pneumonia. However, the general public does not need to prepare special goggles. They only need to wash their hands frequently, do not touch the east and the west, do not rub the eyes, nose and nose, and avoid the chance of the virus entering the human body through the mucosa.
I would like to remind everyone that try not to wear contact lenses and use ordinary glasses or light-colored sunglasses to reduce the chance of the virus entering the conjunctiva of the eye. This is because contact lenses are not easy to flow out of the mouth and contact lenses do not protect the conjunctiva effect. Although the effect of glasses or sunglasses is not as comprehensive as that of goggles, it can still receive basic protective effects.
Should I wear a mask and wash my hands frequently at home?
In fact, wearing a mask at home is not much of a necessity. We just need to do disinfection at home. Of course, if there is a sick person at home, then you must bring a mask, do a good job of disinfection before removing the mask. This is also just in case.
Pay attention to the following points when washing your hands:
1. Rub the hands carefully for more than 15 seconds during the whole process of hand washing;
2. Pay special attention to thoroughly washing the parts wearing rings, watches and other decorations. Remove the accessories from your hands and clean them thoroughly. Wearing a ring on your hand will cause a local "special zone" to hide dirt and dirt. If you don't pay attention, it will cause bacteria to leak out of the net.
3. Jewelry such as rings or watches should also be cleaned if possible.
In the face of an epidemic, in addition to the necessary prevention and control measures, the most important thing is to maintain a good optimistic attitude. Don't panic, as long as you take protective measures, you will be able to prevent the disease.
