[Case Study] The Registration of Medical Isolation Mask

Medical isolation masks, as important medical protective materials for epidemic prevention and control, played an important role during the epidemic. According to Chinese medical device regulations, medical isolation masks are managed as the Class I medical device. The CIRS Group has compiled the technical requirements for the filing and recording of medical isolation masks in accordance with relevant laws and standards and requirements.

③ Appearance: The medical isolation mask should be clean and free of stains and dirt; it should be complete without damage or separation; the lens should be smooth, free of burrs and scratches; the color of the lens should be transparent and the sight should be clearly visible when worn.

④Structure: The medical isolation mask should be able to completely cover the wearer's face. It should be kept upright in the longitudinal direction without sagging, and there should be no creases when it is bent horizontally.

⑤ Elongation rate of rubber band (for rubber band fixing band): The elastic band should be flexible and the elastic band elongation rate should be less than a certain value.

⑥Installation and fixing requirements: The breaking strength at the connection between the fixing device and the mask should not be less than a certain value; the joint of the medical isolation mask should be firm. The horizontal plane is subjected to a certain gravitational pull, and the vertical direction is subjected to a certain gravitational pull, which lasts for 30s, and should not fall off.
