[0002] In medical research and clinical practice, neuroelectrophysiological reflex testing is a commonly used examination method to evaluate the functional status of the nervous system and diagnose related diseases. This test usually requires the subject's limbs to be stably fixed on the test bench to ensure the accuracy and reliability of the test results.

[0003] However, traditional neuroelectrophysiological reflex test benches have some limitations in design and use. First, the support table structure may not be suitable for all subjects' body shapes, resulting in unstable limb fixation or discomfort for the subjects during the test. Second, traditional test benches often lack flexibility and adjustability and cannot be adjusted according to the specific needs of the subjects and test requirements. In addition, the support table may shake or tilt during the lifting and moving process, which will have an adverse effect on the test results. Utility Model Content

Figure 4 A schematic diagram of a fixing mechanism in a neuroelectrophysiological reflex test bench provided in one embodiment of the utility model.

[0048] like Figures 1 to 4 As shown, a neuro-electrophysiological reflex test platform of an embodiment of the utility model includes: a base 1, a lifting mechanism 2, a limiting mechanism 3, a support platform 4 and a fixing mechanism; the support platform 4 is arranged above the base 1 and is parallel to the base 1; the lifting mechanism 2 is arranged between the support platform 4 and the base 1, and is used to connect the support platform 4 and the base 1; the extension and retraction of the lifting mechanism 2 controls the lifting and lowering of the support platform 4; the limiting mechanism 3 is arranged between the support platform 4 and the base 1, and is used to limit the support platform 4 to maintain vertical movement during lifting and lowering; the fixing mechanism is arranged on the upper surface of the support platform 4, and is used to fix the limbs.

[0049] The base 1 is a flat plate structure with a relatively large weight, which can ensure that the neuroelectrophysiological reflex test bench will not fall over due to an experimenter on the support platform 4 during use.

[0050] In this embodiment, the base 1 is a circular or square flat plate structure.

[0051] The support platform 4 is a flat plate structure and is used to support the experimenter.

[0052] In this embodiment, the support platform 4 is circular, and its area is larger than that of the base 1. This design can ensure that when the medical staff's body is close to the support platform 4, there is enough space around the base 1 for standing.

[0053] The lifting mechanism 2 can be a gas cylinder or a hydraulic cylinder. When a hydraulic cylinder is used as the lifting mechanism 2, a corresponding hydraulic oil tank, pipeline and pump body are also required. The hydraulic cylinder can be selected and designed by technicians in this field according to the existing technology, which will not be described here.

[0054] The bottom of the lifting mechanism 2 is fixedly mounted at the center of the base 1. The top of the lifting mechanism 2 (the top of the cylinder rod or the top of the piston rod of the hydraulic cylinder) is fixedly connected to the bottom center of the support platform 4.

[0055] There are multiple limiting mechanisms 3, and they are evenly distributed. Specifically, there are four limiting mechanisms 3. When the base 1 is a square, the four limiting mechanisms 3 are respectively arranged near the four corners of the square.

[0056] In a preferred embodiment, the limiting mechanism 3 includes a lower limiting rod 31 and an upper limiting rod 32; the lower limiting rod 31 is a hollow structure, and the bottom of the lower limiting rod 31 is fixedly connected to the base 1; the top of the upper limiting rod 32 is fixedly connected to the support platform 4, and the lower end of the upper limiting rod 32 is inserted into the lower limiting rod 31.

[0057] The upper surface of the support platform 4 is provided with four groups of adjustment grooves.

[0058] Each group of adjustment grooves is used to connect one end of a limiting mechanism 3, and the other end of the limiting mechanism 3 is used to fix the limb. Each group of adjustment grooves includes a plurality of clamping grooves 5 and a connecting groove 6; the plurality of clamping grooves 5 are arranged in sequence at intervals; the connecting groove 6 is used to connect the plurality of clamping grooves 5. A fixing groove 7 is provided at the bottom of the clamping groove 5 and close to the center of the support platform 4.

[0059] The length direction of the clamping groove 5 is perpendicular to the diameter of the circle where the support platform 4 is located, and the length direction of the connecting groove 6 coincides with the diameter of the circle where the support platform 4 is located.

[0060] There are four groups of adjustment grooves; one adjustment groove is set on each of the four radii of the two mutually perpendicular diameters of the circle where the support platform 4 is located.

[0061] The beneficial effects of the above scheme are mainly reflected in the following aspects:

[0062] Enhanced flexibility and adaptability: The design of multiple snap-in slots 5 means that the fixing mechanism can flexibly select and quickly position between different snap-in slots 5 according to actual needs, so as to adapt to the fixation of limbs of different sizes and positions, thereby improving the adaptability of the device to different subjects and different detection parts.

[0063] Precise positioning and fixation: multiple snap-in slots 5 are connected via the connecting slot 6, and the fixing mechanism can select the most suitable snap-in slot 5 for fixation, thereby achieving precise placement and firm clamping of the subject's limbs, and ensuring the accuracy and effectiveness of the neuroelectrophysiological reflex test.

[0064] Easy and quick operation: The snap-on design simplifies the connection and disassembly process between the fixing mechanism and the support table 4, making it convenient for medical staff to quickly adjust the fixing position, reducing unnecessary operation time and improving work efficiency.

[0065] The fixing mechanism includes a clamping rod 8 and a fixing belt 9 connected to each other; the clamping rod 8 is clamped with the adjustment slot to clamp the fixing mechanism in the adjustment slot; the fixing belt 9 is used to fix the limb. As needed, the clamping rod 8 can be inserted from the clamping slot 5 and then placed in the fixing slot 7 to fix the clamping rod 8.

[0066] The connection method of the clamping rod 8 and the fixing belt 9 is not limited, as long as the two can be connected and the clamping rod 8 is not affected in being placed in the clamping groove 5 and the fixing groove 7 .

[0067] The specific selection of the fixing belt 9 is prior art and can be purchased in the market. No further description is given here.
