Those skilled in the art will understand the specific meanings of these terms in this application.

[0038] This application provides an embodiment of a device for testing the lower limb muscle strength of non-human primates. Figures 1 to 5 .

[0039] The device for testing the lower limb muscle strength of non-human primates in this embodiment includes: a device body, which includes an animal fixing box 1, an animal entry and exit door 9 is provided on the back of the animal fixing box 1, an animal head fixing device is provided on the top of the animal fixing box 1, and through holes 11 for allowing the animal's arms to be extended are symmetrically provided on both sides of the animal fixing box 1. A muscle strength testing device and a fixing ring 5 for fixing to the ankle of the animal are provided in the animal fixing box 1. The muscle strength testing device is connected to the fixing ring 5 and is used to detect the lower limb muscle strength data of the non-human primate.

[0040] It should be noted that this device is simple to operate, low-cost, can achieve non-invasive detection, and can accurately record the lower limb muscle strength data of non-human primates, thereby scientifically and objectively observing the degree of recovery of their lower limb muscle strength. It fills the gap in the field of behavioral test data of non-human primates (mainly macaques and crab-eating macaques) where there is no dedicated equipment for lower limb muscle strength testing, which is conducive to the objectivity, scientificity and accuracy of animal medical experimental data.

[0041] The above is the first embodiment of a device for testing the lower limb muscle strength of non-human primates provided in the embodiments of the present application. The following is the second embodiment of a device for testing the lower limb muscle strength of non-human primates provided in the embodiments of the present application. For details, please refer to Figures 1 to 5 .

[0042] The apparatus for testing the lower limb muscle strength of a non-human primate in this embodiment comprises a device body, which includes an animal holding box 1, an animal entry and exit door 9 on the back of the box, an animal head securing device on the top of the box, and symmetrical through-holes 11 on both sides of the box for extending the animal's arms. Inside the box 1, a muscle strength testing device and a fixing ring 5 for fixing to the animal's ankle are installed. The muscle strength testing device is connected to the fixing ring 5 and is used to detect the lower limb muscle strength data of the non-human primate. Specifically, the animal entry and exit door 9 is provided with a bolt.

[0043] It is understandable that, because non-human primates are different from humans and cannot cooperate with human commands, they need to be restrained to prevent them from moving around and affecting the test results. During use, the non-human primate is placed through the animal entrance door 9 into the animal restraint box 1. The head of the non-human primate is secured using the animal head restraint device. The animal's arms are then extended and secured through the through-holes 11 on both sides of the animal restraint box 1. The fixing ring 5 is then secured to the animal's ankles to perform the non-human primate's lower limb muscle strength test.

[0044] The device body also includes a balance frame 2, an animal fixing box 1 is arranged in the middle of the balance frame 2, and an animal arm fixing device 4 is arranged on the top of the balance frame 2. By setting the balance frame 2, the device as a whole is more stable and the shaking of the device body can be further avoided.

[0045] The animal arm fixing device 4 can be a handcuff fixed on the top of the balance frame 2. When in use, the arms of the non-human primate can be extended from the through holes 11 on both sides of the animal fixing box 1 and then fixed on the handcuffs on the top of the balance frame 2.

[0046] The animal fixing box 1 is provided with a touch screen control device 7 and an electric stimulator 8. The touch screen control device 7 is electrically connected to the electric stimulator 8 and the muscle strength testing device respectively. The touch screen control device 7 is used to control switches and read data.

[0047] It is understandable that the electrical stimulator 8 can perform artificial stimulation through its own electric needle, or the electrical stimulator 8 can be connected to the fixing ring 5 through the wire 12 to achieve electrical stimulation of the animal's ankle.

[0048] The muscle strength testing device includes a single chip microcomputer 6 and a bridge sensor. The bridge sensor is detachably mounted on the fixing ring 5 and is connected to the single chip microcomputer 6 via a signal line 13 for transmitting measured data back to the single chip microcomputer 6 for calculation.

[0049] The animal head fixing device includes a collar slot 3 provided on the top plate of the animal fixing box 1. Preferably, a fixing screw for fixing the animal collar inserted into the collar slot 3 is vertically threaded on the top plate of the animal fixing box 1.

[0050] A support plate 14 is provided in the animal fixing box 1 , and the interior of the animal fixing box 1 is divided into an upper space and a lower space by the support plate 14 ; the upper space is used to accommodate non-human primates, and the lower space is used to place a muscle strength testing device.

[0051] An openable and closable acrylic plate observation window 10 is provided on the front of the animal fixing box 1. The thickness of the acrylic plate observation window 10 can be 10 mm, which is strong enough and can be used to observe the animal's behavior to avoid accidents.

[0052] The animal fixing box 1 is made of medium-density fiberboard, which has moderate strength and can effectively resist attacks from animals without causing any injuries.

[0053] During the specific implementation, the animal is placed into the animal fixing box 1 through the animal entry and exit door 9, the animal's collar is inserted into the collar slot 3 on the top plate of the animal fixing box 1, and the fixing screws are tightened to fix the animal's collar; then, from the back of the animal fixing box 1, the animal's arms are passed through the through holes 11 outside the animal fixing box 1 and fixed to the handcuffs on the top of the balance frame 2; then, the two fixing rings 5 ​​are respectively fixed to the ankles of the animal's lower limbs, and the electric stimulator 8 is controlled to start by the touch screen control device 7. Since the electric stimulator 8 is connected to the two fixing rings 5 ​​respectively through the wires 12, the left and right lower limbs can be stimulated according to the experimental needs, or they can be stimulated at the same time (the experimenter can also use the electric needle provided by the electric stimulator 8 for artificial stimulation). At this time, the animal's lower limbs will be lifted up after being stimulated, and the bridge sensor installed on the fixing ring 5 will transmit the data to the single-chip microcomputer 6 for calculation, and then the single-chip microcomputer 6 transmits the data to the touch screen control device 7 to display the real-time data, so that the experimenter can record it conveniently.

[0054] This device for testing the lower limb muscle strength of non-human primates fills the gap in the field of behavioral test data of non-human primates (crab-eating macaques) in the lack of dedicated equipment for lower limb muscle strength testing. It has the advantages of visualization, simple operation, non-invasive detection, low cost, and clear data display.

[0055] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
