What if the mask rope is too long? Just stick the long part with tape. Or tie the rope of the mask in a knot. There should be a size when you buy it.
Take ordinary medical masks as an example. Ordinary medical masks are usually made of rubber bands for convenience. The face of the mask has two sides, with several folds on the face and a hard strip on the side. When wearing, there is a hard strip on the face first, because the hard strip can be used to pinch the bridge of the nose to ensure the tightness of the mask. Then the mask folds must be downward, because if the folds are upward, bacteria, viruses or dust can easily stay in the folds.
How to wear a mask rope Ordinary masks usually wear masks on both sides of the ears. Some masks have four ropes, that is, band masks, which can be tied like this:
First: Tie the two straps on the same side of the mask together, and then tie them to the ears, paying attention to the tightness. Pay attention to stick your face, stick a mask on your face, nose and mouth, and hang the ropes at both ends on your ears with both hands; Pull the folds of the mask up and down with both hands at the same time, so that the mask completely covers the nose, mouth and chin; Finally, press both sides of the bridge of the nose with your forefinger, so that the upper end of the mask is close to the bridge of the nose. ?
Second: Tie the upper and lower straps around the head and neck respectively, with the upper strap tied around the ear and the next strap tied around the neck. Popular cartoon masks on the market are usually tied directly to the ears.
The correct way to wear a mask is to wash your hands before wearing a disposable mask, because disposable masks are generally disinfected. The main purpose of hand washing is to prevent unclean hands from polluting the inside of the mask, causing germs to be inhaled into the human body through the respiratory tract and causing diseases. ?
Hang a mask. Pick up both sides of the disposable mask with your index finger and thumb, stick the mask horizontally above the nose and mouth of your face, and then hang the ropes at both ends on your ears by hand. ?
Pull the mask up and down with both hands at the same time so that the mask completely covers the mouth, nose and chin.
Press the mask tightly. When wearing the mask, press the metal strips on both sides of the bridge of the nose tightly with the forefinger of both hands, so that the upper end of the mask is close to the bridge of the nose, maintaining a three-dimensional space, which can not only prevent dust from entering, but also ensure smooth breathing.
How to distinguish 1 on the front and back of a mask? Look at the connection of the mask. I think this method is unacceptable, because each manufacturer's is different. For example, some masks have an outgoing interface, but the outgoing interface in Figure 3 is also included.
2. Touch the metal strip, sometimes you can't see it just by looking at it, so touch it, and the metal strip protrudes very outward. This is what the pharmacy told me.
3. Look at these folds. Some masks have three folds, that is, when the metal strip is on it, the folds are downward and outward, and the folds are upward. If it's white, the same is true for a 30% discount.
However, some white masks have many wrinkles. How to distinguish them? What the drugstore told me was that the outward folds were outward and the inward folds were toward the face.
Of course, the best way is to read the instructions, but none of them are packed in the pharmacy, so you can also ask the people in the pharmacy, and everyone must wear masks correctly! ! !
