Correctly Identify the Front and Back of Disposable Masks

The front and back of a nonwoven sterile surgical medical face mask can be distinguished by metal strips, creases, thread ends, color and fabric.

1. Classification of metal bars

Distinguished by metal strips, usually the color of disposable face mask china is mostly the same, which makes it difficult for people to distinguish. Generally, the metal strip is above and the side that protrudes outward is the outside, and the opposite side is Is inside.

2. Classification of creases

It is distinguished by the crease, the side with the crease upward is the inner surface, and the opposite is the outer surface.

3. Thread distinction

The side with the thread is the outside, on the contrary, the side without the thread is the opposite.

4. Color distinction

The colors of the front and back of the mask are mostly different, the outer surface is mostly light blue or dark; the inner layer is mostly white or light.

5. Fabric differentiation

According to the degree of smoothness, the outer part of the mask is mostly smooth because it has a water blocking function; while the inner part is mostly made of a material with good air permeability, which is close to the skin and facilitates breathing.

Precautions for use:

1. Use time

From the perspective of human physiological structure, since the blood circulation of the nasal mucosa is very strong, the passage in the nasal cavity is very tortuous, and the nasal hair forms a filtering "barrier". When air is sucked into the nostril, the airflow forms a vortex in the tortuous passage, which warms the airflow sucked into the nasal cavity.

Some tests have shown that when cold air at minus 7°C is sucked into the lungs through the nose, the airflow has been heated to 28.8°C, which is very close to the temperature of the human body. If you wear a mask for a long time, the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity, so you cannot wear a mask for a long time.

2. Cleaning and maintenance

The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt on the outer layer will be directly attached to it. It becomes a source of infection by inhaling the body when it is face. When you are not wearing the mask, you should fold it into a clean envelope and fold the side close to your nose and mouth. Don't just put it in your pocket or hang it around your neck.

3. Properly handle

Daily use of masks should be handled properly. Masks that have been used by patients or used during care should be placed in a lined container in the patient room before processing.
