What is a medical protective mask?
The medical protective mask has the protective performance of surgical mask and particle protective mask at the same time. It is used in hospitals to filter particles in the air and block droplets, blood, body fluids and secretions. It is also a Class II medical device product and must comply with the mandatory standard GB19083-2010.
The first version of GB19083 was formulated urgently during the SARS outbreak in 2003, and the old version of the standard was revised in 2010. GB19083 has clear requirements for the filtering efficiency and tightness of respirators, which is similar to GB2626-2006; The medical protective mask is also a surgical mask, so it is not allowed to set an exhalation valve to prevent the droplets generated by the wearer from polluting the surgical wound through the exhalation valve; The blue-green color shown on the surface of many medical protective masks is just a habit of the medical industry, and the materials on the outer surface of the masks can block the body fluid splashing. In this regard, non medical particle protective masks are usually not considered.
On the surface, it is difficult to distinguish disposable masks from medical surgical masks. The disposable masks specially used in the hospital belong to Class I medical devices, and the products have medical product registration certificates. The pharmaceutical industry has no standards for such products, and the manufacturers only produce them according to the enterprise standards. The disposable medical mask has no protection function to prevent body fluid from splashing, and its filtering efficiency for droplets is uncertain, so it cannot be used for surgical operation.
Disposable masks are made of non-woven materials, which are very thin and light. They do not need to fit tightly with the face when wearing. They have low resistance to airflow, high wearing comfort, and are also very cheap. They are usually discarded after use. They are widely used in food processing and the production of some electronic devices, which can prevent operators from polluting food or workpieces; In hospitals, medical staff will provide disposable medical masks for patients with respiratory infectious diseases to use when entering and leaving public areas, which can help reduce the risk of disease transmission.
With the strengthening of the public's awareness of influenza prevention, more and more people have realized that wearing disposable masks can reduce the risk of transmitting the disease to their families and colleagues when they have a cold or flu, which is worth advocating.
