Living creature breeding device for judging breathing by using change of purple litmus reagent

Abstract

The invention relates to the technical field of bioengineering, and provides a living creature breeding device for judging breathing by using the change of a purple litmus reagent. The living creaturebreeding device comprises a machine body, wherein the inner wall of the machine body is fixedly connected with a breeding box; and the top of the breeding box is fixedly connected with a photoresistor. According to the living creature breeding device for judging breathing by using the change of the purple litmus reagent, a mouse breathes to generate carbon dioxide, the color of the purple litmusreagent continuously changes, and light rays in contact with the photoresistor continuously change; when a resistance value of the photoresistor reaches a critical value, a threaded sleeve controls anair bag positioned at the left end of a machine to be compressed; a threaded sleeve controls an air bag positioned at the right end of the machine to expand; a threaded sleeve enables a valve close to the center of the machine to be opened to introduce fresh air and suck out unclean air; the threaded sleeves drive sliding blocks to move; the sliding blocks and push plates jointly act to spray chemicals in a chemical box into the air bags; the air is exhausted after being treated in a unified way; and the harm caused by pathogenic bacteria carried by the mouse on the life and health of peopleis avoided.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a biological breeding device which utilizes the change of purple litmus reagent to judge respiration. Background technique [0002] Bioengineering is an emerging technology based on biological theory and technology combined with modern engineering technology. Bioengineering has a wide range of applications and has a huge impact on the life and medical care of human society. With the development of the times, People have continuously researched various drugs through bioengineering, among which the experimental mice have contributed a lot. [0003] In the existing technology, the breeding of mice is continuously ventilated, and the gas inside the breeding device is directly discharged without treatment. The internal air may contain viruses, and the direct discharge endangers people's life safety, and the physical condition of the mice begins to change. Judging with the nake...

Problems solved by technology

[0003] In the existing technology, the breeding of mice is continuously ventilated, and the gas inside the breeding device is directly discharged without treatment. The internal air may contain viruses, and the direct discharge endangers people's life safety, and the physical condition of the mice begins to change. Judging with the naked eye, you can only study when the mice are dying, and miss the research time. Therefore, a biological breeding device that uses the change of purple litmus reagent to judge breathing came into being.
