Vertical Lift Intermittent Hypoxia Rat and Mouse Breeding Cabin

Abstract

The invention relates to an experimental animal feeding cabin, in particular to a vertical lifting intermittent hypoxia rat and mouse feeding cabin, which comprises feeding cages, hypoxia feeding cabins formed by closed cabin bodies and buffer cabins formed by closed cabin bodies. An isolating cabin door is arranged between each buffer cabin and each hypoxia feeding cabin. The buffer cabins are overlaid on the hypoxia feeding cabins. A buffer cabin door is arranged at the top of each buffer cabin. The feeding cages are respectively arranged above the hypoxia feeding cabins and the buffer cabins. A feeding cage lifting driving device drives the feeding cages to periodically pass through the buffer cabins to get in and out of the hypoxia feeding cabins. Since the feeding cages, the buffer cabins and the hypoxia feeding cabins are vertically arranged and the feeding cages are driven to be lifted up and lowered down by using the feeding cage lifting driving device, the vertical lifting intermittent hypoxia rat and mouse feeding cabin has the advantages that the occupied area is smaller, the field utilization ratio is higher, the noise is low, the manufacturing of linear tracks is not needed, the structure is compact, the working reliability is higher, the feeding cabin is convenient to control and the manufacturing cost is lower.

Description

technical field [0001] The invention relates to an experimental animal breeding cabin, in particular to a vertical lifting intermittent hypoxia rat breeding cabin. Background technique [0002] Sleep apnea syndrome (SAS), especially obstructive sleep apnea-hyponea syndrome (OSAHS), is a chronic sleep-respiratory disorder with a high incidence, which seriously affects people's physical and mental health. At present, the etiology and pathogenesis of the disease are still unclear, and there are certain limitations in the research on the human body, so the relevant animal research is particularly important. [0003] Because rats have spontaneous apnea during sleep, their brain electrical activity is similar to that of humans, and they sleep for a long time, are well tolerated, and are easy to raise. Therefore, rats are a good animal model for studying sleep apnea syndrome. Generally, the maintenance time of the gas concentration in the sealed cabin can be controlled, so that t...

AI Technical Summary

Problems solved by technology

Although the animal breeding cabin has been greatly improved in terms of saving nitrogen, it was also found in the process of production and use that the animal breeding cabin occupies a large area, and a set of linear track intermittent hypoxic animal breeding cabins has only one feeding cabin. The requirements for the site are high, and the efficiency is not high. Now the animal experiment group usually needs 6-8 groups at a time, which occupies a lot of the experimental site; in addition, the processing of the linear track is more troublesome and costly

The power source needs compressed air, and the noise is loud, so it is not suitable for schools and scientific research places that need to be quiet.
