[0028] See also Figure 1-Figure 4 As shown, the utility model provides an infection prevention nursing respirator, comprising a gas storage tank 1, a mask assembly 3 and a sealing member 4; a gas delivery assembly 2 is arranged at the upper end of the gas storage tank 1, and specifically, the gas delivery assembly 2 comprises a gas delivery hose 201, a valve 202 is arranged at one end of the gas delivery hose 201 close to the gas storage tank 1, a connecting pipe 203 is arranged at one end of the gas delivery hose 201 far from the gas storage tank 1, and a connecting thread 204 is arranged on the connecting pipe 203. The above design can ensure the storage and supply of breathing gas for the respirator;

[0029] See also Figure 2-Figure 4As shown, the mask assembly 3 is connected to the gas storage tank 1 through the gas delivery assembly 2. Specifically, the mask assembly 3 includes a replaceable mask 301, and the replaceable mask 301 is provided with an elastic band 302. A connecting seat 303 is provided on the left side of the replaceable mask 301, and a threaded hole 304 is provided on the left end of the connecting seat 303. Further, the threaded hole 304 corresponds to the connecting pipe 203, and the threaded hole 304 and the connecting thread 204 are installed in coordination. The above design can lay a foundation for the connection and installation of the mask assembly 3. A bacteria-proof chamber 305 is provided on the right end of the connecting seat 303. Further, the left end of the bacteria-proof chamber 305 is connected to the threaded hole 304, and the right end of the bacteria-proof chamber 305 is connected to the right side of the replaceable mask 301. The above design can ensure the normal circulation of breathing gas. The adsorption bacteria-blocking layer 306 and the filtering bacteria-blocking layer 307 are arranged at both ends of the adsorption bacteria-blocking layer 306. By adopting the above design, the connection and installation of the mask assembly 3 can be realized, and the normal use of the mask assembly 3 is ensured, which lays the foundation for the normal use of the respirator. Furthermore, the adsorption bacteria-blocking layer 306 is paved with activated carbon, and the filtering bacteria-blocking layer 307 is made of sponge material. By adopting the above design, the filtering and sterilization of the respiratory gas can be realized; the seal 4 is located at the connection between the gas transmission assembly 2 and the mask assembly 3.
