High-grade biological safety protection type pathogen airborne transmission experiment device for medium-sized and large animals

Abstract

The invention discloses a high-grade biological safety protection type pathogen airborne transmission experiment device for medium-sized and large animals, and can perform droplet transmission experiment on animals large in volume, such as monkeys. The high-grade biological safety protection type pathogen airborne transmission experiment device comprises a first exposing cavity and a second exposing cavity, wherein the first exposing cavity is used for accommodating germy animals, and the second exposing cavity is used for accommodating healthy animals; connecting openings are formed in the first exposing cavity and the second exposing cavity, and the first exposing cavity communicates with the second exposing cavity through the connecting openings; a wind transporting and filtering deviceis mounted on the first exposing cavity; and a wind exhausting and filtering device is mounted on the second exposing cavity. The high-grade biological safety protection type pathogen airborne transmission experiment device disclosed by the invention has the technical essentials that during the experiment, wind is transported to the inner part of the first exposing cavity by the wind transportingand filtering device to allow the germy animals to respire, waste gas exhaled by the germy animals enters the second exposing cavity to allow the healthy animals to respire, and then the wind exhausting and filtering device is used for exhausting the gas exhaled by the healthy animals, so that droplet transmission and infection experiment of the medium-sized and large animals is performed; and the whole system is simple in structure, and the patent blank in the respect of droplet transmission and infection of domestic medium-sized and large animals is filled.

Description

technical field [0001] The invention relates to an experimental device for carrying out droplet-transmitted infection on animals, in particular to a high-level biological safety protection type medium and large animal pathogen airborne experimental device. Background technique [0002] At present, in order to quickly and accurately diagnose infectious diseases, it is often necessary to conduct comprehensive inspection and analysis of pathogenic microorganisms. Inhalation toxicology is a science that studies the various conditions, laws and mechanisms of the occurrence, development and elimination of the toxic effects of inhalable substances on the body, as well as the risk assessment of inhalable substances. His professional research contents mainly include: the physical and chemical properties of various substances in the air; the basic biology of the respiratory tract; the deposition and retention of inhaled substances in the body and their interactions with important syst...

AI Technical Summary

Problems solved by technology

[0003] Some animals, such as mice, take up little space due to their small size. Multiple mice can be placed in one experimental device space at the same time, but for some larger animals such as monkeys, they take up a lot of space. It is difficult for devices such as three-level cabinets to accommodate two or more monkeys and monkey cages at the same time. Therefore, it is necessary to provide an infection system for medium and large animals for droplet transmission
