Problems solved by technology

[0005] The above training devices are all used for passive exercise training of rat hindlimbs, but still have the following defects: (1) not suitable for mice
The size of the mouse is small and the limbs are short. The above training device is difficult to fix the mouse, which will affect the accuracy of the results of the passive movement training of the limbs.
(2) The hindlimb immobilization method causes discomfort in the hindlimbs of small animals, which may affect the accuracy of the results of passive movement training of the limbs
(3) Unable to complete the circular trajectory of the small animal's hind limbs in the natural position of the bent legs
(4) Cannot control and display the passive movement speed of limbs in real time

Embodiment 1

[0054] See figure 1 , figure 1 It is a structural schematic diagram of the passive movement training machine for small animal limbs of the present invention. The passive movement training machine for small animal limbs is provided with:

[0055] A fixator 1 is used to fix the small animal and expose the hind legs of the small animal. Go to see figure 2 , figure 2 It is a schematic diagram of the structure of the fixer, wherein, the upper picture is the side view of the fixer, the middle picture is the bottom view of the fixer, and the lower picture is the top view of the fixer. The fixer 1 is composed of a cylinder 101 , a head restricting device 102 , a tail restricting device 103 and a fixing seat 104 . Both ends of the cylinder 101 are open, and the walls at both ends are respectively provided with a first axial slot 106 and a second slot 107; Animal head accommodation groove 108, the two ends of described animal head accommodation groove 108 all communicate with th...

Embodiment 2

[0073] The passive movement training machine for small animal limbs in this embodiment is basically the same in structure as the passive movement training machine for small animal limbs described in Embodiment 1, except that the upright column of the support frame in this embodiment has a height adjustment function. See Figure 7 , Figure 7 It is a schematic diagram of the structure of the column. The column 143 includes a first adjustment column 1431 and a second adjustment column 1432. The lower end of the second adjustment column 432 is inserted into the first adjustment column 1431 and can slide along the up and down direction. An outer wall of an adjusting post 1431 is provided with a fixing hole, and a screw cooperates with the fixing hole so that the first adjusting post 1431 and the second adjusting post 432 are relatively fixed.

[0074] In this embodiment, the upright column has the function of height adjustment, so the contact between the palm surface of the small...

Abstract

The invention relates to a passive sport training machine for small animal limbs. The machine comprises: a fixator which consists of a cylinder, a head limiting device and a tail limiting device, where the wall of the cylinder is provided with two leg openings; a power adapter; a switch; a single-chip microcomputer (with a display) which is used for controlling and displaying the running speed ofa motor in real time; an actuator; a motor; a driving wheel; a driven wheel; a synchronous belt; an optical axis; an optical axis support; two connecting rods; two pedals; and a support frame. The invention takes into account various details of the passive sport training of the small animal limbs, and the designed passive sport training machine for small animal limbs can effectively fix animals with small size and short limbs and reduce the discomfort of the small animals in the experiment, is conducive to the development of passive sport training experiments for small animal limbs, obtains more objective and accurate experimental results, and is convenient for experimental operation.

Description

technical field [0001] The invention relates to the technical field of passive movement training of limbs, in particular to a passive movement training machine for limbs of small animals. Background technique [0002] Passive movement training of the limbs plays an important role in the rehabilitation training after the limbs lose their motor function. It can prevent muscle atrophy, relieve muscle stiffness, and promote functional recovery. Passive movement training of small animal limbs plays an important role in the research of rehabilitation-related scientific issues. Therefore, some scholars have invented a rat lower limb passive movement training machine, and use a jacket-like coat to fix rats for lower limb passive movement training. Mice are widely used in scientific research, and there are more mouse models to choose from, such as transgenic mice. Due to the small size and short limbs of mice, it is difficult to be fixed, and the precision of the training machine is...
