Masks are now our necessities, but there are many kinds of masks. What is the difference between surgical masks and medical protective masks? Masks are now our necessities, but there are many kinds of masks, so what is the difference between surgical masks and medical protective masks?
1、 Difference between surgical mask and medical protective mask
1. Different functions
The surgical mask is mainly used in medical clinics, laboratories, operating rooms and other highly demanding medical environments, with high safety factor. It can block particles larger than 4 microns in diameter, and can block about 70% of bacteria and viruses, but it does not fit the face, and it breathes smoothly when worn; The medical protective mask is mainly used when there is serious environmental pollution or sudden medical infectious disease (such as respiratory infectious disease). The safety factor is much higher than the surgical mask, and the diameter that can prevent transmission through the air is ≤ 5 μ Mg infection factor or close contact (≤ 1m) with diseases transmitted by droplets can protect 95% of bacteria, viruses, etc., and precisely fit the face.
2. Different materials
Surgical masks are made of mask, shaped parts, straps and other components, and are generally made of nonwoven materials; The medical protective mask face is divided into three layers: the inner layer is ordinary sanitary gauze or non-woven fabric, the middle layer is ultra-fine polypropylene fiber melt-blown material layer, and the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer.
2、 Which is better, surgical mask or medical protective mask
Medical protective mask. From the comparison of product functions, it can be concluded that the medical protective mask will be better. Whether in terms of the degree of protection against viruses or in terms of material, the medical protective mask will be better than the surgical mask in general, with better safety factor and can play a better protective role.
Although the medical protective mask is very good, it is not that the surgical mask is bad. The shell mask is also a good medical product, and can also play a good protective role. It is also cheap, and has strong breathability when used. If the virus environment is not serious, it is completely OK to wear the surgical mask. The medical protective mask is still recommended to be used in a place with strong professionalism.
3、 What do surgical masks refer to in three layers
The standard surgical mask is also divided into three layers, including the inner layer, the middle layer and the outer layer. The inner layer is made of materials with hygroscopic effect, the outer middle layer is made of materials with filtering effect, and the outer layer is made of materials with waterproof effect, thus forming a surgical mask. The main raw material of the surgical mask is polypropylene. The fiber diameter of this material can reach 0.5-1 microns, which is very good in filtration, shielding, thermal insulation and oil absorption, Therefore, these three layers of fabric can also be used as the basis for judging the authenticity of surgical masks.
4、 Classification standard of respirator protection grade
It is more common in our life to divide them into two categories: medical masks and industrial masks. The protection level of masks is generally divided into four levels, namely A, B, C, and D. The corresponding protection effect of each level is 90%, 85%, 75%, and 65%, which are respectively applied to serious pollution, serious and below pollution, serious and below pollution, moderate and below pollution.
