Simulation smoke exposure experimental box

Abstract

The application discloses a simulation smoke exposure experimental box which comprises a box body and a sealing cover, wherein a smoke inlet is arranged at the bottom part of the box body, a smoke outlet is arranged on the side wall of the top part, an annular groove is arranged at the top part, and liquid is contained in the annular groove; and the sealing cover is covered on the annular groove, an annular vertical wall is arranged thereon, the annular vertical wall is embedded in the annular groove, and the bottom part of the annular vertical wall is immersed in the liquid, thereby not only sealing the box body, but also forming a gas channel between the sealing cover and the annular groove for leading gas in the box body to escape when the pressure in the box body is larger, and further keeping the pressure in the box body constant. Therefore, the simulation smoke exposure experimental box provided by the embodiment of the application can control the gas pressure in the exposure experimental box when carrying out an exposure experiment, avoid an experimental animal in the box from producing barotraumas, lead the smoke inhalation to become the sole wound-causing factor, avoid the bias of the barotraumas and improve the accuracy and the scientificity of exposure experimental data.

Description

technical field

[0001] The present application relates to the field of biomedical poisoning equipment, in particular to a simulated smoke poisoning experiment box. Background technique

[0002] In recent years, with the rapid development of social economy, the living environment and life style of human beings have also undergone tremendous changes. At the same time, the incidence of fires is also rising, seriously threatening people's survival and health.

[0003] According to the statistics of the global fire survey by the International Fire Protection Technical Committee, in recent years, 6 to 7 million fires have occurred in the world every year, and about 60,000 to 70,000 people have died in fires; The fourth place in the world. A large number of studies have shown that 85% of the victims in the fire died from the inhalation of toxic fumes rather than direct burns. The research on fire burns has been paid attention to early, and remarkable research results have been o...
