To play a real protective role

This is all exquisite

When should I wear a mask

※ When going to the hospital to see a doctor or visiting a patient, especially when going to the fever clinic or respiratory department of the hospital;
※ When going to crowded places such as supermarkets, shopping malls, and cinemas;
※ In order to prevent the spread of the disease to others, you should wear a mask in time when you have symptoms of respiratory diseases such as fever, cough, and runny nose;
※ It is recommended to wear a mask during outdoor activities in haze weather.

How to choose a mask

Ordinary cotton masks, various net red masks
The material may be cotton, gauze, wool, canvas and velvet, etc., which are mainly used to keep warm. Because the material itself is not dense enough to prevent infection, it is not recommended to wear it.

Ordinary protective mask with breathing valve
There is an exhalation valve, which is used to prevent dust and haze, but it cannot be used to prevent respiratory infections.

Disposable medical mask

Under normal circumstances, disposable medical masks can be used in places where people are going out.

Medical surgical masks
It can prevent respiratory infections to a certain extent. Please note that it is a medical surgical mask, not an ordinary protective cleaning mask. To go to the fever clinic or respiratory department of the hospital, or to contact patients with respiratory diseases, medical surgical masks are recommended.

Medical protective masks
Compared with medical surgical masks, medical protective masks have a higher level of protection. They are "fighters" in masks, but at the same time they are more expensive. Applies to the following situations:

Contact with patients with airborne infectious diseases, such as tuberculosis patients;
Contact with patients with diseases for which medical protective masks are clearly recommended for protection, such as plague, highly pathogenic avian flu, SARS, etc.

01
Distinguish the pros and cons

Masks are divided into front and back, top and bottom. The front (outward) is mostly light blue or dark, the reverse (inward) is mostly white or light, and the metal strip with the nose clip inside is the top.

02
Handwashing

You need to wash your hands before wearing a mask, because the mask is relatively sterile. If your hands are dirty, touch the mask and rub the dirt on your hands against the mask, and the mask will be worn for nothing.

03
Put on
Make sure that the reverse side of the mask is facing inward, the end with the metal strip is facing up, and the ropes at both ends are hung on the ears.

04
Squeeze and stretch
Use both hands to press the metal strips on both sides of the bridge of the nose to make the upper end of the mask close to the bridge of the nose, and then stretch the mask downwards so that the mask does not leave wrinkles and better covers the nose and mouth.

How to take off the mask

Do not touch the front of the mask (contaminated surface);

* Untie the lower strap first, and then untie the upper strap;

※Pinch the strap of the mask with your fingers and throw it into the medical waste container. Wash your hands after removing the mask.

There are "3 points" in the use process

1. It is necessary to shape the nose clip, carefully cover the mouth and nose with a mask and fasten it tightly to minimize the gap between the face and the mask;

2. You must avoid touching the outside of the mask (contaminated surface) during use, and wash your hands before wearing, before and after removing, and after touching the outside (contaminated surface);

3. Must be used once! Throw it away after use. Avoid re-wearing. After the mask becomes damp or contaminated with moisture, put on a new clean and dry mask, preferably every 2 to 4 hours.

Special groups of people must be careful when choosing protective masks:

Pregnant women who wear protective masks should pay attention to their own conditions and choose products with better comfort. Before wearing them, they should consult a professional physician to confirm that their physical condition is suitable;

The elderly and patients with chronic diseases have different physical conditions. For example, patients with cardiopulmonary diseases may cause discomfort after wearing them, and they should seek professional guidance from a doctor;

Children are in the stage of growth and development, and their faces are small. It is difficult for general masks to achieve a close-fitting effect. It is recommended to choose child protective masks produced by regular manufacturers.
