What is the difference between ordinary medical masks and medical surgical masks?

The appearance of ordinary medical masks and medical surgical masks is almost the same, the only difference is the middle interlayer.

The number of layers of ordinary medical masks is 2 layers, the number of medical surgical masks is 3 layers, the middle layer is the core of medical surgical masks, the outermost layer is a waterproof layer, and the inner layer is a moisture-proof and water-absorbing layer, which is made of meltblown cloth. The material with the function of filtering particles, which is the fundamental difference from ordinary medical masks.

Therefore, ordinary medical masks cannot prevent the new crown virus, while medical surgical masks can prevent the new crown virus.

The difference between ordinary medical masks and medical surgical masks
1. Medical surgical mask: It can filter most viruses and bacteria. The quality and clinical application of medical surgical masks will be more extensive and suitable for surgical operations. For medical personnel without N95 masks, medical surgical masks can be used instead for disinfection and isolation. Work.

Medical surgical masks can protect against most pathogens, such as bacteria and viruses, so WHO recommends that medical staff wear protective masks against particulate matter during outbreaks to prevent viral infections in hospital air. Mainly divided into medical protective masks and medical surgical masks.

2. Ordinary medical masks: The range of bacteria and viruses that can be filtered is relatively narrow.

A general medical mask is a tool used to filter the air entering the nose and mouth to prevent harmful gases, odors and droplets from entering the wearer’s mouth and nose. Mainly divided into cotton masks, non-woven masks, polymer masks, activated carbon powder filter masks, activated carbon fiber felt masks.

In the fight against the new crown pneumonia epidemic, wearing masks correctly plays an important role in prevention. We must choose medical surgical masks and above for self-protection. If conditions permit, we can choose N95 masks, which can also avoid virus-containing aerosols from causing harm to us, and can achieve effective virus isolation standards. Do not touch the outside of the mask while wearing it. When taking off the mask, be scientific and standardized, do not touch the outside of the mask, and keep a safe distance of 1m-2m from others.
