High-grade biosafety protection type air propagation experimental device for pathogens of medium and small animals

Abstract

The invention discloses a high-grade biosafety protection type air propagation experimental device for pathogens of medium and small animals. The high-grade biosafety protection type air propagation experimental device can be used for carrying out a droplet propagation experiment on the medium and small animals such as rats, mice, martens and rabbits. The high-grade biosafety protection type air propagation experimental device comprises a biosafety cabinet, wherein the biosafety cabinet comprises an exposure cavity for accommodating healthy animals and bacteria-carrying animals; a sealed experimental box is arranged in the exposure cavity; the healthy animals and the bacteria-carrying animals are placed in the experimental box; the biosafety cabinet is provided with an air supply filteringdevice and an air exhaust filtering device; the air supply filtering device is used for supplying air into the exposure cavity; the air exhaust filtering device is used for purifying air in the exposure cavity and exhausting the air; the experimental box comprises an air inlet and an air outlet; the air inlet communicates with the air supply filtering device; and the air outlet communicates withthe air exhaust filtering device. According to the technical key points, the experimental animals are placed in the experimental box and the propagation experiment is not directly carried out in the biosafety cabinet, so that the pollutant diffusion range is reduced and the experiment is safer; and the section of the droplet propagation experimental box is small and an accurate experimental resultis easy to obtain.

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 small and medium-sized 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 importan...

AI Technical Summary

Problems solved by technology

[0003] In conventional experimental ideas, the carrier animals and healthy animals are often placed in the same biological safety cabinet or in different biological safety cabinets for droplet transmission experiments, and the exposure chamber of the biological safety cabinet is relatively large, increasing The diffusion range of pollutants is reduced, which reduces the accuracy of the experiment
