Embodiment 1

[0036] figure 1 Schematic appearance of the simulated smog poisoning experiment box provided for the implementation of an example of this application Figure 1 .

[0037] figure 2 Schematic appearance of the simulated smog poisoning experiment box provided for the implementation of an example of this application Figure II .

[0038] Such as figure 1 and figure 2 As shown, the simulated poisoning experiment box includes: a box body 1 and a sealing cover 2 , and the sealing cover 2 covers the top of the box body 1 .

[0039] The bottom side wall of the box body 1 is provided with a smoke inlet 4, and the top side wall is provided with a smoke outlet 3. During the poisoning experiment, the experimental animals are placed inside the box body 1, and the smoke enters the box body 1 through the smoke inlet 4. , and then go out from the smoke outlet 3 to complete the smoke poisoning experiment. The material of the box body 1 is a transparent material, so that in the experime...

Embodiment 2

[0046] Such as Figure 6 As shown, it is the same as Embodiment 1. In the embodiment of the present application, the top of the box body 1 is also provided with an annular groove 5, and the sealing cover 2 is also covered on the annular groove 5, and the annular vertical wall 21 on it is also embedded. In the annular groove 5, and the bottom is submerged below the water surface in the annular groove 5, the top of the box body 1 is sealed. However, in the embodiment of the present application, the annular vertical wall 21 on the sealing cover 2 is not movably embedded in the annular groove 5, but is detachably connected with the annular groove 5 by bolts 6, and the sealing cover 2 and the annular vertical wall There are gaps between 21 and the annular groove 5 .

[0047] When using this simulated poisoning experiment box to carry out the poisoning experiment, when the pressure in the box 1 exceeds the preset value, although the sealing cover 2 cannot move, the gas in the box w...

Embodiment 3

[0049] On the basis of Embodiment 1 and Embodiment 2, the simulated poisoning test chamber provided by the present application further includes: a porous partition 7 and a mixing fan 11 .

[0050] The porous partition 7 is arranged inside the box body 1 to isolate the box body 1 into a plurality of independent spaces for placing animals to be tested during experiments. Such as Figure 7 As shown, in the embodiment of the present application, there are six porous partitions 7, and the box body 1 is divided into upper, middle and lower layers, and each of the middle layer and the lower layer has three independent spaces. In the embodiment of this application, as Figure 8 As shown, in the embodiment of the present application, raised ribs 9 and fixing grooves 10 are also provided on the inner wall of the box body 1, and the raised ribs 9 are horizontally distributed on the inner wall of the box body 1 in a ring shape, and are used for fixing horizontally placed porous The part...

Abstract

The invention 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...
