Pathogenic bacteria inhalation toxicology experimental equipment for respiratory system

Abstract

The invention provides pathogenic bacteria inhalation toxicology experimental equipment for a respiratory system. A closed cabin used for accommodating experimental animals is connected with a bacteria liquid aerosol atomization device capable of precisely controlling the bacteria carrying amount; the atomized aerosol is sent into the closed cabin to form a simulation environment with pathogenic bacteria; a transparent sealed door can be conveniently opened and closed to observe inside animals; the inside of the closed cabin can be sterilized and disinfected by an ultraviolet sterilizing lamp and an ozone sterilizer; after toxic exhaust gas is controlled by a solenoid-controlled valve and is disinfected by a high-temperature gas burning pipe, the toxic exhaust gas is pumped out via a negative-pressure pump; a gas environment monitoring and controlling device is arranged in the closed cabin; the closed cabin is connected with the negative-pressure pump, a compressed air source and the solenoid-controlled valve; a computer and a printer can observe and control according to a programmed program to finish an infection simulation experiment of the inhalation pathogenic bacteria; and an experiment process parameter is stored or printed. The pathogenic bacteria inhalation toxicology experimental equipment for the respiratory system has the effect that the safe and convenient simulation experiment equipment capable of precisely and quantitatively controlling the environment with the pathogenic bacteria is provided for the medical respiratory infection research.

Description

technical field [0001] The invention relates to a poison exposure experiment equipment, in particular to a respiratory system pathogenic bacteria inhalation poison exposure experiment equipment. Background technique [0002] It is a very common and serious problem that pathogenic bacteria infect respiratory diseases through gaseous transmission. In the current medical research, in view of the wide spread of airborne diseases and the research on the prevention, treatment and related pathology and pharmacology of respiratory diseases that are more harmful to humans, it is necessary to use bacterial liquid aerosols with specific pathogenic bacteria to expose and poison experimental animals. However, the accurate control of the number of specific pathogenic bacteria and air concentration, the purity of pathogenic bacteria, pollution interference, anti-virus diffusion, and experimental environment requirements have always been difficult problems in the scientific community. Previ...

In the current medical research, in view of the wide spread of airborne diseases and the research on the prevention, treatment and related pathology and pharmacology of respiratory diseases that are more harmful to humans, it is necessary to use bacterial liquid aerosols with specific pathogenic bacteria to expose and poison experimental animals. However, the accurate control of the number of specific pathogenic bacteria and air concentration, the purity of pathogenic bacteria, pollution interference, anti-virus diffusion, and experimental environment requirements have always been difficult problems in the scientific community. Previously, there was no special research on pathogenic bacteria spreading infection through gaseous state. Simulated experimental equipment for systemic diseases, similar experiments can only be performed on animals with nasal drops, and cannot provide accurate and rigorous experimental data. There is also a certain risk of infection, which will seriously threaten the life safety of experimenters, thus restricting related scientific research. research development
