Negative pressure isolator-type device for experiments of pathogen airborne infection

The invention discloses a negative pressure isolator-type device for experiments of pathogen airborne infection. The device can be applied to experiments of droplet transmission of rats, mice, marten,rabbits and other small-and-medium animals. The device includes a negative pressure glove box, wherein the negative pressure glove box includes an exposure chamber, the exposure chamber is internallyprovided with a first animal cage and a second animal cage, and the first animal cage is used for accommodating bacteria-carrying animals; the second animal cage is only used for accommodating healthy animals, the first animal cage and the second animal cage are capable of moving in the exposure chamber, and the exposure chamber communicates with an air inlet filter device and an air exhaust filter device; and the air inlet filter device is used for sending air for inhalation of the bacteria-carrying experimental animals into the first animal cage, and the air exhaust filter device is used for discharging exhaust gas
