Measuring device for physiological state body length of experimental animal mouse

Abstract

The invention provides a measuring device for physiological state body length of an experimental animal mouse. The measuring device comprises a preparation bin, a body length measuring channel, a pedestal and an image recording unit. The pedestal is provided with an inclined plane, and the body length measuring channel is obliquely arranged on the inclined plane of the pedestal. The bottom end ofthe body length measuring channel is an inlet and the top end of the body length measuring channel is an outlet. The outlet of the preparation bin is connected with the inlet of the body length measuring channel. Scales are arranged on the bottom surface of the body length measuring channel. The both side channel walls of the body length measuring channel can move towards the two sides in the direction perpendicular to the body length measuring channel. The image recording unit is used for shooting and recording images of the experimental animal mouse in the body length measuring channel. Themeasuring device of the present invention can realize accurate and non-invasive measurement for body length of the experimental animal mouse.

Description

technical field [0001] The invention relates to the field of measuring device technology (biotechnology), in particular to a device for measuring the body length of experimental animals in the physiological state of rats. Background technique [0002] With the rapid development of modern medicine, experimental animals are more widely used in various fields, especially rats and mice among experimental animals, due to their advantages such as low price, small size, easy breeding, strong reproductive ability, and similar gene sequence to humans And is commonly used. [0003] Body length is one of the most basic physiological indicators of experimental animals. In the construction and evaluation of many commonly used animal models, body length is an indispensable indicator. For example, the Lee's index of experimental mice is a common indicator for judging the degree of obesity in rodents. , is calculated from two indicators of body weight and body length. [0004] At present,...

AI Technical Summary

Problems solved by technology

[0004] At present, there are mainly two ways to measure the body length of rodents. One is to measure the body length with a soft ruler in the awake state of experimental animals. However, due to the activity of experimental animals and the strong flexibility of the body, it is difficult to measure the actual body length of animals. , the data obtained have large errors; the second is to measure the body length of the animal after anesthesia. Although the body length measurement of the animal is accurate under anesthesia, the effect of anesthesia on the animal does not apply to all experimental projects, single or frequent animal Anesthesia may affect the nervous system, exercise state, water intake, food intake, etc., leading to deviations in some key measurement indicators, which in turn affect the experimental conclusions
