Detailed Description

Wear at first through conduction pipe 3 port and gauze mask field traditional chinese medical science with surgical gauze mask filter or N95 filter or non-medical gauze mask filter or non-woven fabrics filter and fixed lid and be connected with the external world, let a breach 4 buckle the bridge of the nose again with the bridge of the nose, reciprocate and make bridge of the nose let a breach 4 buckle the bridge of the nose completely and airtight, the maxilla lets a breach 5 thereupon, the mandible compensates protruding 6, the mandible lets a breach 7 buckle in the cheek, wear to hang area (8) in ear or head.

Wearing the nose bridge protection device is firstly connected with the outside through a conduction pipe 3 port and a gas mask field via non-woven fabrics, melt-blown fabrics, activated carbon filter paper, chemical protection filter cloth, a chemical protection filter bag and a fixed cover, then buckling the nose bridge abdicating notch 4 on the nose bridge, moving up and down to enable the nose bridge abdicating notch 4 to completely buckle the nose bridge and be airtight, then buckling the maxilla abdicating notch 5, the mandible compensation protrusion 6, the mandible abdicating notch 7 on the cheek, and wearing a hanging belt (8) on the ear or the head.

Wearing the nose bridge abdicating device, firstly connecting the conduction tube 3 port with a respirator or a sputum suction machine or a respirator or first-aid equipment replacing artificial respiration, then buckling the nose bridge with the nose bridge abdicating notch 4, moving up and down to make the nose bridge abdicating notch 4 completely buckle the nose bridge and be closed, then buckling the maxilla abdicating notch 5, the mandible compensation protrusion 6 and the mandible abdicating notch 7 on the cheek, and wearing the hanging belt (8) on the ear or the head.

The invention relates to a body and mouth and nose edge sealing detection of a closed facing model of a buckle cover, which comprises the steps of firstly buckling a nose bridge abdicating notch 4 on a nose bridge, moving up and down to enable the nose bridge abdicating notch 4 to completely buckle the nose bridge and to be closed, then buckling an upper jaw abdicating notch 5, a lower jaw compensation bulge 6 and a lower jaw abdicating notch 7 on a cheek, wearing a belt on ears or heads, lightly covering a conduction pipe 3 by using a palm of a user to ensure that air does not flow in the suction process through the conduction pipe 3, enabling the wearer to have no air flow in the facing shell in suction, namely completely sealing, and if air flow flows in from the mouth and nose edge, indicating that the closed facing model of the buckle cover is not suitable.

The invention relates to a body of a buckle closure veneer modeling, which solves the problem that hardware materials can not be directly attached to the edge of a mouth and a nose to realize sealing until the past, unless customized by individuals or sealed by a silica gel pad.

Due to the large difference in cheek contours between the yellow and caucasian or black individuals and the limited sampling of the numerous caucasians or black individuals required by the inventors, the high suitability of the present invention is limited to the yellow population.
