When in specific use, when epidemic diseases explode, a medical worker puts down the support legs 27 from the grooves 26 through the folding mechanism 28, places the inflatable airbag cushion 24 in the first groove 23, inflates the inflatable airbag cushion 24 through the inflation port 245, then lifts the upper sliding plate 21 of an infected person or a suspected infected person, then takes out the negative pressure hood 1, inserts the first side plate 101, the second side plate 102, the second sliding rod 107 and the fourth sliding rod 114 into the grooves 26, pulls the buckle 34 to buckle the buckle 34 with the buckle base 33, and through the magnetic sealing strips fixedly arranged on one side of the clamping groove 31 and the movable plate 32, the first side plate 101, the second side plate 102, the second sliding rod 107 and the fourth sliding rod 114 and the locking mechanism 3 are in a sealing state, pulls the first sliding rod 106 and the third sliding rod 113 to the locking mechanism 3 to be locked through the matching of the buckle 34 and the buckle base 33, so that a small negative pressure isolation chamber is formed between the first negative pressure hood film 108 and the second negative pressure hood film 115, the air tightness of the negative pressure hood 1 is increased through the magnetic sealing strip, then the exhaust fan is connected with the air inlet 111, the power interface of the exhaust fan is connected with the configuration power supply 211 to exhaust air in the negative pressure hood 1, so that an infected person or a suspected infected person is in an isolation cabin in a sealed negative pressure environment to avoid pathogen leakage and propagation, then the air filter and the biological sign monitor are respectively connected with the air filter interface 103 and the biological sign monitoring interface 104, the power interfaces of the air filter and the biological sign monitor are respectively connected with the configuration power supply 211, air in the negative pressure hood 1 is in a circulation state through the air filter, the biological sign monitor is used for monitoring the vital signs of the infected person or the suspected infected person, the oxygen bottle is fastened at the bottom of the fixing plate 22 through the oxygen bottle fixing device 210 arranged at the bottom of the fixing plate 22 to carry out continuous oxygen delivery in the negative pressure hood 1, medical personnel pulls the U-shaped handle 25 to slide through the universal wheels 29 fixedly connected with the bottoms of the supporting legs 27, infectious people or suspected infectious people can be transferred quickly, when the medical personnel pushes the infectious people or suspected infectious people into a CT room for X-ray detection through the sliding rails arranged between the sliding plate 21 and the fixed plate 22, the medical personnel can pull the sliding plate 21 to the CT bed only by adjusting the telescopic height of the supporting legs 27 to be consistent with the height of a CT bed and pulling the pull handle arranged on one side of the front surface of the sliding plate 21, so that the infectious people or suspected infectious people can carry out X-ray detection when lying in the negative pressure hood 1, the leakage of pathogens is avoided, after the medical personnel transfers the infectious people into a ward through the pull groove 212 arranged on one side of the front surface of the sliding plate 21, the object placing plate 213 arranged in the pull groove 212 in a sliding way is pulled, and the medicines to be treated can be placed on the object placing, the infectious patients can be treated more conveniently and effectively.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
