Do you know the correct way to use medical masks?
How to use the medical mask:
1, whether it is a disposable mask, or a medical mask, in fact, there are positive and negative, oh, take a disposable mask, the color is deep, the front should be facing outwards, and the medical mask also has a nose clip metal strip .
2, the face should be the opposite side of the medical mask, that is, the lighter side, in addition, it should be noted that the part with the metal strip should be above the mask, do not wear the reverse.
3. After clearing the front, back, upper and lower ends of the mask, wash your hands first and make sure that the mask is correct. Then hang the ropes at both ends on your ears.
4, the last step, which is the most important step, is also the metal strip problem mentioned above. After the mask is worn, it is necessary to press the metal strips on both sides of the bridge of the nose with both hands so that the upper end of the mask is close to the bridge of the nose and then down. Stretch the mask so that the mask does not leave wrinkles, it is best to cover the nose and mouth, so the effect of the medical mask will be better.
Misunderstanding of medical masks:
1. Ordinary disposable masks are not necessarily sterilized or disinfected, and are only suitable for general use.
2, ordinary medical masks or disinfected and sterilized, suitable for medical institutions, but did not have the requirements of bacterial filtration rate.
3, disposable surgical mask (medical surgical mask) must meet industry standards, PFE> 30%, BFE> 95%, sterile level, suitable for medical staff's diagnosis and treatment activities and surgery.
We often say that disposable masks and masks that can be reused are not effective dust-proof. Their production standards do not require dust-proof sputum. They are mainly used to filter materials in the air and cannot form around the nose and mouth. Effective enclosed area.
