A huge number of animals are used in experiments worldwide each year, and rodents are the most commonly used experimental animals by medical researchers at home and abroad. In medical animal experiments, especially those involving Traditional Chinese Medicine (TCM), safe and effective fixation of experimental mice is often required. Procedures like orbital vein blood sampling, tail vein injection / blood sampling, acupuncture treatment, and respiratory rate monitoring all place high demands on the effective fixation of experimental mice.

DETAILED DESCRIPTION

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example

[0032] like Figures 1-8 As shown, an embodiment of the present invention provides a multifunctional laboratory mouse fixation device, comprising a fixing seat 1, a base 2 is provided on the lower end surface of the fixing seat 1, a movable seat 3 is provided above the fixing seat 1, an auxiliary adjustment component 6 is provided on the lower end surface of the movable seat 3, a bearing platform 9 is provided above the movable seat 3, a control panel 8 is installed on the outer side of the bearing platform 9, and an auxiliary fixing component 7 is provided on the upper end surface of the bearing platform 9;

[0033] The auxiliary adjustment assembly 6 includes a first drive motor 62, a threaded adjustment rod 63, a limiting sleeve 64, a limiting slide 65, an adjustment column 67, a second drive motor 68 and a rotating seat 611. The first drive motor 62 is provided on the upper end surface of the fixed seat 1, and the output end of the first drive motor 62 is clamped with a threaded adjustment rod 63 through the motor shaft. The upper end surface of the fixed seat 1 is provided with a limiting sleeve 64, the lower end surface of the movable seat 3 is provided with a limiting slide 65, the central position of the lower end surface of the movable seat 3 is provided with an adjustment column 67, the upper end surface of the movable seat 3 is provided with the second drive motor 68, and the rotating seat 611 is provided above the movable seat 3;

[0034] The auxiliary fixing assembly 7 includes a fixing plate 71, a tightening strap 72, a mounting seat 74, a winding roller 75 and a third drive motor 78. The fixing plate 71 is embedded in the upper end surface of the supporting platform 9, the tightening strap 72 is provided on the upper end surface of the fixing plate 71, the mounting seat 74 is provided on the lower end surface of the fixing plate 71, the winding roller 75 is rotatably provided on the lower end surface of the mounting seat 74, and the third drive motor 78 is fixedly installed on the lower end surface of the mounting seat 74.

[0035] In this embodiment, there are four groups of specifications of the limiting sleeve 64 and the limiting slide rod, and four groups of specifications of the limiting slide rod.

The limiting slide rod 65 slides tightly along the inner wall of the limiting groove 641. The limiting sleeve 64 is slidably connected to the limiting slide rod 65 through the limiting groove 641. The design of the limiting sleeve 64 and the limiting slide rod 65 can limit the moving trajectory of the movable seat 3 in the vertical direction, so that the movable seat 3 moves more stably relative to the fixed seat 1, which is beneficial to adjust the height of the supporting platform 9 in the experiment.

[0043] Working principle:

[0044] The user places the experimental mouse on the upper end surface of the supporting platform 9 and passes the limbs of the experimental mouse through the tightening restraint belt 72, and then operates the corresponding control panel 8 to control the corresponding third drive motor 78 to turn on. The third drive motor 78 is turned on and drives the winding roller 75 to rotate. The rotation of the winding roller 75 drives the tightening restraint belt 72 to tighten and firmly fix the limbs of the experimental mouse on the upper end surface of the supporting platform 9 to facilitate subsequent experimental operations. During the experiment, the user can control the first drive motor 62 to turn on through the control panel 8. The first drive motor 62 is turned on and drives the threaded adjustment rod 63 to rotate. Since the threaded adjustment rod 63 is engaged with the adjustment column 67 through the threaded groove 671, the rotation of the threaded adjustment rod 63 can drive the adjustment column 67 and the movable seat 3 to move in the vertical direction, thereby facilitating the adjustment of the height of the supporting platform 9. At the same time, the user can The second drive motor 68 is controlled to be turned on through the control panel 8, and the second drive motor 68 drives the active gear plate 69 to rotate. Since the active gear plate 69 and the driven gear plate 613 are engaged with each other, the rotation of the active gear plate 69 can drive the rotating seat 611 to rotate through the driven gear plate 613, thereby facilitating the adjustment of the direction of the supporting platform 9, so that the experimental operation is more convenient and smooth. The instruments and props in the experimental process can be placed on the upper end surface of the shelf. At the same time, the position and angle of the shadowless lamp 5 can be adjusted through the gooseneck tube 52 to provide good lighting conditions for the supporting platform 9. After the experiment is completed, the user can control the third drive motor 78 to be turned on again, and drive the winding roller 75 to rotate in the opposite direction, thereby releasing the tightening restraint belt 72 to the outside. The released tightening restraint belt 72 is released under the guidance of the guide block 73, thereby facilitating the release of the experimental mouse.
