The non-woven fabric headgear 21 is bonded with the protection window 19 to form a headgear, the neck is fastened by the nylon snap fastener tape 25, the whole head is wrapped, so that the outside air can not directly enter the head, and the propagation path of diseases is effectively cut off.
The protective window 19 is made of PET material, has good transparency, is slightly arc-shaped, is a large window, and is convenient for observation and communication.
The oral cavity area of the protection window 19 and the auricle area of the non-woven fabric head cover 21 are processed into screen-shaped structures, and waterproof sound-transmitting films 24 are respectively stuck on the screen-shaped structures, so that voice communication is facilitated.
Two sponge fixing bands 23 are respectively arranged at two inner sides of the upper part of the non-woven fabric head cover 21 and are used for internally fixing the B-shaped protective head cover 20.
There are 1Y-shaped air pipes 22 along the sponge fixing belt 23, the air inlet end of which is connected with the air hose 8, the air outlet ends of the left and right lateral branch pipes extend forward to the forehead area, so that the air from the air-supply assisting fan 7 flows to the forehead, face and mandible area, and the protection window 19 is prevented from fogging.
Two sides of the lower part of the protection window 19 are respectively provided with a mask breather valve 18, and the mask breather valves 18 are one-way valves and are closed during inspiration and opened during expiration to form a breathing gas exhaust channel.
The drink straw channel 17 is positioned in the mandibular area and is a supplement channel for tea, milk and liquid diet, so as to solve the problem that the medical staff can not drink water and diet for a long time. The drink straw channel 17 is in a normally closed state, and when the drink straw cap needs to be used, the cap is opened, and the drink straw is stretched into the oral cavity through the drink straw channel 17.
The working process of the utility model is as follows:
the user bears the equipment on the shoulders, the waistband is fastened between the waists to prevent swinging, then the protective hood 20 is worn, the nylon snap fastener 25 is fastened, the worker assists to connect one end of the air supply hose 8 with the air outlet of the air supply assisting fan 7, and the other end of the air supply hose is connected with the air inlet end of the Y-shaped air supply pipe 22. After wearing, the air supply assisting fan 7 and the cold cathode ultraviolet lamp 27 are sequentially started by pressing a working key on the operation panel. At this time, with the help of the air supply assisting fan 7, the outside air enters the B-shaped protective face mask 20 through the germ filtering device 5, the air buffer chamber 4, the ultraviolet disinfection device 6, the air supply hose 8 and the Y-shaped air supply pipe 22 in sequence for breathing, and the exhaled air is discharged outside through the second mask breathing valve 18. And when a stop key is pressed, the air supply assisting fan 7 and the cold cathode ultraviolet lamp 27 stop working, and a disinfection and sterilization and air supply process is completed.
When water or nutrient substances need to be supplemented, the periphery of the drink straw channel 17 is disinfected, the sealing cover is opened, and the drink straw extends into the oral cavity through the drink straw channel 17.
In the use, filter element piece 2 needs to be changed in good time.
