Description

Technical Field

[0001] The utility model mainly relates to the technical field of biological experimental equipment, in particular to a carbon monoxide hypoxia experimental device for mice. Background Art

[0002] Currently, the equipment used in carbon monoxide anoxic experiments is relatively simple and lacks safety barriers. If concentrated sulfuric acid splashes, it will cause serious harm to experimenters and students. The equipment used in most laboratories is not sophisticated enough. Improper operation may cause the concentrated sulfuric acid and formic acid to continue to react, continuously producing carbon monoxide beyond the experimental requirements.

[0003] Currently, most devices lack carbon monoxide treatment equipment. Carbon monoxide can cause poisoning, so it is necessary to treat the waste gas generated by the experimental device. Utility Model Content

This structural design controls the amount of acid participating in the reaction, thereby controlling the amount of carbon monoxide produced.

[0023] A support rod 11 is fixedly provided on the inner wall of the box body 2, and a clamping jaw 12 is fixedly provided on the other end of the support rod 11. The inner wall of the clamping jaw 12 abuts against the outer ring of the flask 5. The open end of the clamping jaw 12 is fixed by a bolt, and the flask 5 is clamped and fixed by tightening the bolt.

[0024] A support plate 13 is fixedly arranged in an array on the inner wall of the box body 2, and the first peristaltic pump 3 and the second peristaltic pump 4 are fixedly arranged on the top of the support plate 13. The first peristaltic pump 3 and the second peristaltic pump 4 are fixed through this structural design.

[0025] The interior of the filter box 8 is divided into two parts, an upper part and an lower part, which are separated by a partition 17. Several exhaust pipes are fixedly set at the bottom of the partition 17. The upper part of the filter box 8 is provided with activated carbon and the lower part is provided with water. Through this structural design, carbon monoxide is adsorbed, and carbon monoxide leakage and poisoning are monitored and prevented. A one-way valve is fixedly set on the side of the filter box 8 near the bottom of the partition 17.

[0026] The formic acid bottle 6 , the concentrated sulfuric acid bottle 7 , and the observation bottle 9 are all abutted against the tops with sealing plugs 14 , and each connecting pipe passes through the corresponding sealing plug 14 . The formic acid bottle 6 is filled with formic acid, and the concentrated sulfuric acid bottle 7 is filled with concentrated sulfuric acid.
