Multi-functional smoke injury experiment equipment for medical research

Abstract

The invention relates to multi-functional smoke injury experiment equipment for a medical research. The multi-functional smoke injury experiment equipment comprises an injury chamber and a transmission device, wherein the injury chamber is a closed cavity; the transmission device is used for inputting or outputting white mice in an iron cage to the injury chamber; a smoke pot for generating white smoke and injuring the white mice in the iron cage in the injury chamber is arranged in the injury chamber; a monitoring device for monitoring whether fuel combustion of the smoke pot is complete or not, monitoring internal temperature and humidity of the injury chamber and the injury time of the white mice and detecting the ingredients of the white smoke is arranged in the injury chamber; and an adjusting device for adjusting the internal temperature and humidity of the injury chamber is arranged in the injury chamber. The multi-functional smoke injury experiment equipment has the beneficial effects that a military exercise site can be simulated through the equipment, the smoke pot combusts to generate the white smoke to cause inhalation injuries of the white mice, and the white mice reach the expected injuries and survival time, so that an economical, simple and stable small-animal model is provided for research on different degrees of inhalation injuries caused by the white smoke coming from the smoke pot.

Description

technical field [0001] The invention relates to the field of medical research, in particular to a multifunctional smoke-induced injury experimental device used for medical research. Background technique [0002] As a smoke screen shelter, the smoke pot is widely used in fire drills or cover retreats. After the smoke pot is ignited, sparks radiate, and white smoke is produced in a few seconds, and the entire smoking time can last for 6-7 minutes. The study found that the average particle size of the white smoke is 0.1 μm, and the water swelling of the particles is 2-3 μm. Under normal circumstances, particles of this size can be filtered out by a high-efficiency filter mask, but when the filter fails or is not completely filtered, the tiny particles in the white smoke will enter the lungs through the respiratory tract, and even reach as deep as the alveoli , causing acute lung injury (acute lung injury, ALI). Accidental exposure to high concentrations of white smoke, espec...

Problems solved by technology

In previous studies, people paid more attention to the main components of white smoke (zinc chloride, hexachloroethane), ignoring that white smoke is greatly affected by factors such as component ratio, space size, and airflow. Even the in vitro model cannot accurately predict the toxicological behavior of white smoke inhalation injury due to the influence of medium dispersion and solubility factors
