Portion is fixed on arc panel.
The beneficial effects of the utility model：1, arc panel can make the flexes of experimental mouse at certain radian, compare
In the prior art, need manually the back hogback by experimental mouse it is time saving and energy saving to certain radian.2, preceding fixed column is in the first sliding groove
Interior sliding, telescopic rod can extend or shorten, and can meet the fixation on different size experimental mouse head.3, the first spring is utilized
The head of experimental mouse is fixed with the elastic force of second spring, preceding fixed column, rear fixed column, telescopic rod and arc panel are to experiment
Mouse carries out the fixation of four direction, and good fixing effect is beneficial to touch vertebra gap, is conducive to carry out intrathecal injection to experimental mouse.
The curvature of scheme two, the optimization to base case, the arc panel is 0.28.In order to make arc panel crooked experiment mouse
Back to suitable radian, design this prioritization scheme, when the curvature of arc panel is 0.28, the crooked radian of arc panel is big, real
The gap tested between mouse vertebra is big, is conducive to find gap, convenient for carrying out intrathecal injection to experimental mouse.
The inner concave of scheme three, the optimization to scheme two, the arc panel is equipped with multiple annulus.Experimental mouse is during injection
It can be tampered after awake, cause intrathecal injection to fail, therefore design this prioritization scheme, by being inserted in rope in annulus by experimental mouse
Body and tail be fixed.
The surface of scheme four, the optimization to scheme three, the arc panel is equipped with skid resistant course.Experimental mouse is lain prone on arc panel
When, arcuate structure can be such that experimental mouse is slid from arc panel, and the frictional force between skid resistant course and experimental mouse body is big, prevent from testing
Mouse slides from arc panel.
