Shanghai Yifu Packaging Co., Ltd. specializes in the production of various mask packaging bags and roll films: disposable mask packaging bags, N95 mask packaging bags, medical mask packaging bags, PM2.5 mask packaging bags and so on.
So, what are the principles of using masks?
Do not use blindly and do not over-protect.
· Open area, no need to wear a mask.
Cotton gauze masks have no protective effect against virus infection.
· Patients with basic respiratory diseases should use protective masks under the guidance of a doctor.
· Infants and young children who are very young can not wear masks, which can cause suffocation.
How to choose masks scientifically?
Experts said that in addition to providing effective protection, masks must also take into account the comfort of the wearer and not bring about negative effects such as biological hazards. In general, the higher the protective performance of a mask, the greater the impact on comfort performance. When people wear a mask, they have a certain resistance to air flow when inhaling. When the resistance to inhalation is too large, some people may feel dizzy, chest tightness and other discomforts.
Different people's industries are different and their physiques are different, so the requirements for the seal, protection, comfort, and adaptability of masks are also different. For some special groups, such as children, the elderly, people with respiratory diseases and cardiovascular diseases, it is necessary to carefully choose the type of masks, and to ensure safety and prevent accidents such as hypoxia and dizziness when worn for a long time.
How to wear a mask correctly?
Take ordinary medical masks as an example. For the convenience of wearing, ordinary medical masks are usually fitted with rubber ears. The face of the mask has front and back sides, there will be several layers of wrinkles on the face, and there is a hard strip on the side. When wearing, first have the side of the hard strip on top, because the hard strip can be used to pinch the bridge of the nose to ensure the tightness of the mask. Then the folds of the mask must be downward, because if the folds are upward, bacteria, viruses or dust are easily trapped inside the folds.
How often does the mask change?
Because of the different types of masks, different groups of users, and different environments, it is not possible to uniformly specify how long to use the masks. Under normal circumstances, disposable medical surgical masks are recommended to be replaced at least every 4 hours; if the mask is wet or soiled by secretions, or if it is damaged, or if it feels that respiratory resistance increases, it should be replaced immediately.
Can the mask be washed?
Which masks can be recycled safely? Look at the instructions from the mask manufacturer. Regarding N95 masks, the CDC document states that in special cases (when N95 masks cannot meet the needs), it is possible to "extend the use period" and "limited reuse" under strict specifications. Generally, regular cotton masks can be recycled. The manufacturer's instructions do not indicate that the masks can be recycled. In the case of forced use and no other masks are available, special attention should be paid to reuse: first, the scientific method of disinfection; second, dedicated personnel; third, reused masks It can be used at work, in general public places, shopping, shopping malls, etc. It is not recommended for citizens to go to the hospital.
How to clean the mask
The outer layer of the mask often accumulates a lot of dirt, bacteria and other dirt in the outside air, and the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will directly adhere When inhaled on the face, it becomes a source of infection. When not wearing the mask, it should be folded into a clean envelope, and the side that is close to the nose and mouth should be folded inward. Do not put it in your pocket or hang it around your neck.
If the mask gets wet with exhaled heat or saliva, its barrier effect will be greatly reduced. Therefore, it is best to prepare a few more masks in order to replace them, and they should be changed and washed once a day. When washing, first blanch with boiling water for 5 minutes.
Masks should be cleaned and disinfected daily. Both gauze masks and air filter masks can be disinfected by heating. The specific approach is:
1. Cleaning. Gently rub the gauze mask with warm water and soap first. The bowl-shaped mask can be gently cleaned with a soft brush dipped in detergent, and then washed with water. Please be careful not to rub hard, because if the warp and weft gap of the gauze is too large, it will lose the effect of preventing droplets.
2. Disinfection. Soak the cleaned face mask in a 2% peroxyacetic acid solution for 30 minutes or cook in boiling water for 20 minutes or put it in a steamer for 15 minutes, then dry it for later use. This method is suitable for gauze masks and bowl masks.
3. Check. Before using it again, you should carefully check whether the masks and masks are still intact. For gauze masks and masks, you can use the light transmission inspection method, that is, take care of them before the lamp to see if there are obvious light spots, and the middle and edge parts are transparent. Is the rate consistent? If in doubt, replace it with a new one.
Benefits and precautions of wearing a mask
At first, first of all, wearing a mask can prevent viruses and bacteria and protect our own health, especially in hospitals. Everyone must remember that during the SARS period in 2003, whether it was a medical worker or an ordinary person, almost everyone had a mask, which is actually the truth. Now when you come to the hospital, especially when you go to the clinics of the Respiratory, Infectious Diseases, Fever Clinic, and Intensive Care Units, it is recommended that you wear a mask regularly. And recent severe new pneumonia is constantly reminding us of the need to wear masks in a timely and correct manner.
Second, wearing a mask can keep warm and humidify. This can effectively prevent the occurrence of respiratory diseases, which refers to the cold winter. In winter, one of the purposes of wearing a mask is to keep warm. By wearing a mask, we not only protect most of our faces from cold air, but also protect our respiratory tract from cold air. At the same time, the exhaled gas contains a certain amount of water, and wearing a mask can retain a part of the humidity, which will help us to maintain the humidity of the mouth and nasopharynx. Therefore, wearing a mask is helpful for preventing colds and upper respiratory tract infections.
The third advantage of wearing a mask is that it can keep the face in a hidden state. This is because some of our facial diseases may be ashamed to show people, and wearing a mask can indeed protect our privacy.
Please wear your mask in the following situations: 1. In the cold and haze days, the mask does have a certain anti-fog effect; 2. When everyone is engaged in or enters the air-contaminated environment, such as changing water and electricity in decoration workers Friends, friends who need to contact asbestos, etc .; 3. Friends with chronic lung diseases, such as chronic obstructive pulmonary disease. 4. Go to a crowded place and try to wear a mask, which can effectively prevent respiratory diseases.
Twenty-two, wearing a mask in winter, the taboo to pay attention to is not always wearing a mask, some people will wear a mask as soon as they go out, it seems no problem. But this is actually wrong. If the weather is good, we don't have to worry too much about harmful particles outside.
With the mask, we can't breathe fresh air. In this environment, we don't need to wear a mask. Another aspect is that you often wear a mask when you go out. Although it prevents harmful substances from entering the body from the nose, to some extent, it also reduces the ability of the nose to resist the outside world.
即可 Wear a mask in a dusty, poor air environment instead of wearing it often. Wearing a face mask often in winter will actually cause illness? Wear a mask and be careful not to commit 2 taboos
Another taboo is that you don't pay attention to hygiene when wearing a mask. Some people don't pay attention to washing their hands when wearing a mask. You must know that there are many bacteria on your hands. It is also easy to contaminate the mask when it is not clean, which is bad for your health.
How to deal with masks after use?
Used masks, for ordinary people, because the risk is low, directly throw them into the trash. For people with fever, cough, sputum, sneezing and other symptoms, or those who have contacted such people, it is preferred to discard the masks in the yellow trash bin of the medical institution, which will be held by the special cleaning agency as medical waste Transfer and disposal. You can also throw the mask to the trash can, and then use 5% 84 disinfectant solution in a ratio of 1:99, then sprinkle it on the mask for treatment.
Medical mask life
Medical masks can only be used once by one person and should be discarded after being worn for a long time. N95 masks should also be replaced every day if worn for a long time. These masks cannot be used again. Once they are worn, they should also be replaced.
解除 When removing the mask, do not touch the contaminated surface in front of the mask, and hold the strap with your hand to discard the mask.
Throw away disposable masks directly. If it is a disposable mask that may come in contact with infectious germs or viruses, it is best to throw it into the yellow "medical waste" bin.
Is it good to have a breathing valve?
Because doctors and patients wearing masks cannot guarantee that they must be healthy and free of viruses (contagious during the incubation period), and mask airflow with exhalation valve is only one-way protection, and can not cut off the transmission route well. From the perspective of epidemic control, two-way protection is the most correct way, so this type of mask is not recommended.
Notes on the use of masks
1. Pay attention to the expiration date of medical masks
The production validity period of general medical surgical masks is three years, and the production validity period of medical protective masks is five years. Once the validity period of the masks is exceeded, the filtering efficiency and protective performance of the filter materials will be reduced. . Before using a medical mask, be sure to confirm the production date and expiration date.
2. Always wash your hands before and after wearing a medical mask
一定 Be sure to wash your hands before wearing the mask to avoid touching the inner surface of the mask, and try to avoid touching the mask during use to prevent the protection from being reduced. When removing the mask, try not to touch the outside of the mask to prevent bacteria from getting on your hands, and be sure to wash your hands after removing.
3. Masks should not be worn for a long time
In order to prevent infection, some people may wear medical masks all day long, but this will make the nasal mucosa fragile, lose the original physiological function of the nasal cavity, and reduce resistance. Wear a mask.
4.Fold medical masks in ziplock bags when not in use
It is not recommended to take off the mask and plug it directly into the pocket or bag. This will easily cause secondary pollution of the medical mask. Be sure to fold it into a clean ziplock bag and fold the side that touches the nose and mouth inward.
