How can I tell the difference between a medical-surgical and a medical-nursing mask?

The difference between medical nursing mask and medical surgical mask is different in protective role, processing method, composition and structure. 1. The protective role is different: medical surgical masks are resistant to protective bacteria and viruses. Medical care masks are resistant to liquids, filtering fine particles and bacteria. 2. Different processing methods: medical surgical masks are usually processed from masks, shaping parts, harnesses and other components, and play a role in isolation through filtration. Medical care masks are mostly made of one or more layers of nonwoven composite fabrics, and the main production processes include meltblown, spunbond, hot air and so on. 3. Composition structure is different: the standard medical surgical mask has 3 layers, the outer layer has the role of water insulation, and can prevent droplets into the mask inside; the middle layer has the role of filtration, can block some small particles; close to the mouth and nose of the inner layer to play the role of moisture absorption. The medical care mask consists of mask body and tensioning belt, in which the mask body is divided into inner, middle and outer layers, the inner layer is ordinary sanitary gauze, the middle layer is the filtration layer, and the outer layer is the bacteriostatic layer. Different occasions and purposes of use, the type of mask chosen is also different, it is recommended that according to their own needs to choose the appropriate type of mask.
