specific Embodiment approach 1

[0032] Specific implementation mode one: refer to figure 1 and figure 2 Describe this embodiment in detail, the rodent respiratory system exposure poisoning device described in this embodiment, it comprises: smoke collection box 2, flue pipe 3 and smoke box 6;

[0033] The smoke outlet of the smoke collection box 2 is communicated with the smoke inlet of the smoke box 6 through the flue pipe 3 .

[0034] The poisoning device described in this embodiment is divided into three parts. The smoke collection box 2 and the smoke box 6 are connected through the flue pipe 3. In practical application, the cigarette 1 is lit and placed in the smoke collection box 2. The smog is transported to the fumigation box 6 after being transmitted through the flue pipe 3, and the smoke dissipates heat during the transmission process of the flue pipe 3, which can effectively reduce the temperature of the smog, thereby preventing the experimental animals from being scalded in the fumigation box 6, ...

specific Embodiment approach 2

[0035] Specific embodiment 2: This embodiment is a further description of the rodent respiratory system exposure poisoning device described in specific embodiment 1. In this embodiment, the flue pipe 3 is provided with n corners, and n is greater than A positive integer equal to 3.

[0036] The smoke is transmitted in the flue pipe 3 provided with n corners, which can allow the smoke to fully dissipate heat in the flue pipe 3 and ensure that the temperature of the smoke entering the smoke box 6 is the same as the room temperature.

specific Embodiment approach 3

[0037] Specific embodiment 3: This embodiment is to further illustrate the rodent respiratory system exposure poisoning device described in specific embodiment 1. In this embodiment, the smoke inlet of the fume box 6 is provided with an isolation net .

[0038] The isolation net can prevent the excrement of experimental animals from falling into the flue pipe 3, prevent the flue pipe 3 from being blocked, and ensure that the smoke quality is not polluted.

Abstract

The invention relates to a rodent respiratory system exposure contamination device and belongs to contamination devices. The rodent respiratory system exposure contamination device aims to solve the problem that an existing smog contamination device is complex in structure and large in size, a smog collecting part and a smudging part are integrated, and the scald to experimental animals is caused easily. The rodent respiratory system exposure contamination device comprises a smog collecting box, a flue pipe and a fumigation box. The smog collecting box is connected with the fumigation box through the flue pipe, heat generated in smog caused by cigarette burning is reduced, and the temperature in the fumigation box is constant. The rodent respiratory system exposure contamination device is small in size and large in capacity, can perform experimental molding on plenty of experimental animals simultaneously and reduce differences between groups and other environmental disturbance. Gregarious habits of the experimental animals is guaranteed, the normal life environment of the animals is simulated, the animals are subject to no constraint and are in a free movement state, and accordingly more accurate experiment receptors are obtained.

Description

technical field [0001] The invention belongs to a poisoning device, in particular to an animal respiratory system exposure type poisoning device. Background technique [0002] Experimental animal gas poisoning experiment is the basic method of gas toxicity evaluation. Experimental animal gas poisoning device is an important prop in this experiment, which can be used to simulate the toxic environment of poisoning through the respiratory tract, and is widely used in environmental protection, industrial hygiene, Drug research and toxicology research. However, the existing smoke poisoning device has a complex structure and a large volume, and the smoke collection part and the smoke part are integrated, which easily causes burns to experimental animals, uneven temperature, and inconsistent environment, resulting in differences in experimental receptors. Contents of the invention [0003] The present invention aims to solve the problem that the existing smoke poisoning device i...
