Rat tail suspension device based on weightless state simulation

Abstract

The invention discloses a rat tail suspension device based on weightless state simulation. The rat tail suspension device comprises a fixing mechanism and a loading mechanism which are arranged in a cage body, the fixing mechanism comprises a tail fixing shaft, a first soft silica gel sleeve and a metal sleeve which are sequentially sleeved from inside to outside, a spiral through groove is formedin the outer side wall face of the tail fixing shaft in the circumferential direction of the tail fixing shaft, and the loading mechanism comprises a swing type connecting rod shaft, a telescopic bearing shaft and a tail end fixing ring. The swing type connecting rod shaft is movably fixed to the top of the metal sleeve, the telescopic bearing shaft is horizontally arranged under the swing type connecting rod shaft, the tail end fixing ring is a ring body fixed to the top of a supporting block of the telescopic bearing shaft, and the axis of the ring body is perpendicular to the side wall ofthe metal sleeve. The device is simple in structure, reasonable in design and high in practicability, and effectively avoids damage or necrosis of the tail of the rat due to mechanical extrusion forceor airtight reasons.

Description

technical field [0001] The invention relates to the technical field of a weightless state simulation experiment device, in particular to a rat tail suspension device based on the weightless state simulation. Background technique [0002] The development of science and technology promotes the world's exploration of space. Astronauts who have been in the microgravity environment of space for a long time will suffer from severe osteoporosis due to the aggravated bone loss and the inability to generate bone calcium normally. For a long time after arriving on Earth, he could not walk normally, or even stand on his own. Therefore, in order to better solve this problem, it is an effective method to use an animal model that simulates weightlessness on the ground to simulate the skeletal growth state of astronauts in a weightless state in space. Strong practical application significance. [0003] The rat tail suspension experimental device is a means of using rats to simulate weigh...

AI Technical Summary

Problems solved by technology

[0003] The rat tail suspension experimental device is a means of using rats to simulate weightlessness experiments. However, most of the existing experimental devices rely on the stickiness of adhesive tape to seal and paste the rat tail. With the extension of the suspension time, the large The secretion of rat body fluid and the weakening of the adhesive tape, the tail of the rat is easy to fall off, resulting in the failure of the experiment, and even the necrosis of the tail of the rat may be caused by the tight seal

From the previous experimental models, we can find that the smoothness of the tail of the rat and the uncontrollable force during the struggle will cause the tail to fall off or even necrosis due to the seal entrainment or mechanical hard impact during the experiment. This situation undoubtedly occurs declaring the experiment a failure
