[0051] As Figures 1-6 shown, a measurement and evaluation device for children's high and low shoulder scoliosis includes a base 1, on which a linear movement module 3 for driving the footrest 2 to move horizontally is assembled;

[0052] A vertical movement module 4 is fixedly installed on the base 1, and a machine base 5 is fixedly installed on the vertical movement module 4;

[0053] A cross track frame 6 is fixedly installed on one side of the machine base 5 facing the footrest 2. The cross track frame 6 includes four track parts, and a high-definition camera 7 is slidably arranged on each track part.

And the training effect can be tracked in real time.

[0057] As an embodiment further provided by the present invention, Figure 2 As shown, the linear moving module 3 includes a second screw rod 31, a slide groove 21 is provided at the bottom of the footrest 2, and a roller seat 32 circumferentially arranged at the end of the second screw rod 31 is located in the slide groove 21 and slides;

[0058] The second screw rod 31 is threadedly connected to the sliding sleeve plate 22 fixedly arranged in the sliding groove 21;

[0059] The other end of the second screw rod 31 extends into the base 1. A first rotating shaft 33 is rotatably arranged in the base 1. The first rotating shaft 33 is transmission-connected to the second screw rod 31 via a fixedly installed first bevel gear 34.

[0060] It also includes a driving motor 9 which is drivingly connected to the first rotating shaft 33 .

[0061] Specifically, in the embodiment, the first rotating shaft 33 is driven to rotate by the driving motor 9, thereby controlling the second screw rod 31 to run synchronously with the output direction of the driving motor 9, and then controlling the foot platform 2 to move away from the base 1 or close to the base 1. The purpose of moving away is to ensure that the four high-definition cameras 7 are sufficient to obtain image data of the collection area for subsequent data analysis and processing.

[0062] As an embodiment further provided by the present invention, Figure 2 and Figure 3 As shown, the vertical moving module 4 includes a rectangular sleeve rod 41 fixedly welded on the base 1 and an extension rod 42 slidably disposed in the rectangular sleeve rod 41;

[0064] It also includes a drive motor 9 which is transmission-connected to the second screw rod 43 .

[0065] Specifically, the second screw rod 43, driven by the driving motor 9, can drive the extension rod 42 to extend or contract relative to the rectangular sleeve rod 41, so that the four high-definition cameras deployed in the device can adapt to the needs of different patient heights.

[0066] As a further embodiment provided by the present invention, in combination with Figure 4 As shown, a third trapezoidal gear 91 is fixedly installed at the output end of the drive motor 9, and a limiting plate 411 is welded inside the sleeve rod 41. An electric telescopic rod 100 is fixedly installed on the limiting plate 411. The electric telescopic rod 100 is used to drive the U-shaped frame 101 slidably arranged on the limiting plate 411 to slide vertically;

[0067] The U-shaped frame 101 includes a first crossbar and a second crossbar, and a third trapezoidal gear 102 is rotatably arranged on the first crossbar, and a fourth trapezoidal gear 103 is rotatably arranged on the second crossbar;

[0068] The third trapezoidal gear 102 is slidably assembled on the rectangular part at the end of the second lead screw 43;

[0069] The fourth trapezoidal gear 103 is slidably assembled on the rectangular part at the end of the first rotating shaft 33;

[0070] The fourth trapezoidal gear 103 and the third trapezoidal gear 102 can be meshed and driven with the third trapezoidal gear 91.

[0071] Specifically, the linear movement module 3 and the vertical movement module 4 share a drive motor 9. When it is necessary to control the movement of the linear movement module 3, the electric telescopic rod 100 can be driven to move upward at this time. Synchronously, the U-shaped frame 101 moves upward. At this time, the fourth trapezoidal gear 103 is meshed and driven with the third trapezoidal gear 91, and the driving method of the vertical movement module 4 is the same.

[0074] Furthermore, a drive shaft sleeve 201 is rotatably arranged in the machine base 5 along the horizontal direction and coaxially. A sixth trapezoidal gear 202 is fixedly installed on the drive shaft sleeve 201. The sixth trapezoidal gear 202 is meshed with the two fifth trapezoidal gears 81 of a group;

[0075] The output shaft of the drive motor 200 passes through the two drive shaft sleeves 201;

[0076] A ring seat 203 is fixedly installed on the drive shaft sleeve 201. Four windows are arranged on the ring seat 203 in a circumferential array. A frustum-shaped rubber column 204 is rotatably arranged in the window;

[0077] A winding motor 205 is fixedly installed on the annular seat 203. The winding on the winding motor 205 sequentially passes through the other end of the frustum rubber column 204, and rotates and fits against the output end of the driving motor 200 to maintain synchronization during the winding of the winding motor 205.

[0078] Specifically, in the embodiment, when it is necessary to drive the two high-definition cameras 7 in the horizontal direction to approach or move away from each other, then drive Figure 6 the winding motor 205 on the first transmission shaft sleeve 201 shown to operate, so as to wind the wire. During the process, the four frustum rubber columns 204 are driven to fit on the output shaft of the driving motor 200, so that the output shaft of the driving motor 200 is synchronized with the first transmission shaft sleeve 201. Similarly, when it is necessary to drive the two high-definition cameras 7 in the vertical direction to approach or move away from each other, then drive Figure 6 the winding motor 205 on the second transmission shaft sleeve 201 shown to operate, so as to wind the wire. During the process, the four frustum rubber columns 204 are driven to fit on the output shaft of the driving motor 200, so that the output shaft of the driving motor 200 is synchronized with the first transmission shaft sleeve 201.

[0079] Embodiment 2

[0080] Combined with Figure 7 and Figure 8 shown, a measurement and evaluation method is applied to the children's high and low shoulder and scoliosis measurement and evaluation device provided in Embodiment 1, and includes the following steps:

[0081] S01. Locate by collecting the marked points on the human back through four high-definition cameras 7, including:

[0082] Taking the spinous process of the seventh cervical vertebra as the first reference point and marking it as point d;

[0083] Taking the bilateral acromion positions as the second reference point and the third reference point respectively, and marking them as point a and point c respectively;

[0084] Taking the highest point of the head as the fourth reference point and marking it as point b;

[0085] S02. Start the light source lamp integrated on the high-definition camera 7 to assist in locating points a, b, c, and d, and sequentially collect the data of the four points. The data includes height data;

[0086] S03. Mark the four points a, b, c, and d on the grid, then connect the obtained points a and c, connect the obtained points d and b, and respectively calculate the shoulder slope angle θ. The formula is as follows:

[0087]

[0088] S04. Repeat the above steps regularly, record the bevel angle θ, and combine the height, age, and weight data of the subject to obtain a dynamically changing curve table and generate a postural assessment form.

[0089] Specifically, utilize the precise capture ability of four high-definition cameras (7) to accurately locate the key marked points on the human back. The specific operation is as follows: Select the position of the spinous process of the seventh cervical vertebra as the crucial first reference point and clearly mark it as point d; then, determine the acromion positions on both sides of the human body as the second and third reference points respectively, and give them clear marks, namely point a and point c; finally, regard the highest point of the head as the fourth reference point and mark it as point b. The accurate marking of these four points provides a solid foundation for the subsequent steps. Immediately afterwards, activate the advanced light source lamp integrated on the high-definition camera (7). This step is aimed at assisting in more accurately locating points a, b, c, and d. Through the illumination of the light source, collect the data of these four key points in sequence, especially their height data, which are crucial for subsequent evaluations. Subsequently, clearly mark the four points a, b, c, and d on the grid and perform connection operations based on these points. Specifically, connect point a and point c to form the reference line of the shoulder; at the same time, connect point d and point b as the reference line of the spine. On this basis, use professional mathematical formulas to accurately obtain the shoulder bevel angle θ. This angle is a key indicator for evaluating the symmetry of the shoulder and spine. To ensure the accuracy and dynamics of the evaluation, it is necessary to repeat the above steps regularly and record the bevel angle θ data obtained from each measurement. At the same time, combine the basic information such as the height, age, and weight of the subject to generate a detailed dynamically changing curve table. On this basis, further generate a postural assessment form to provide the subject with an intuitive postural assessment result.

[0090] It should be noted that the method in the above embodiments is implemented by the circuit on the circuit board arranged in the machine base 5 and the control program, and the corresponding operations can be controlled by an infrared sensor or manually.

[0091] It should be noted that the light source lamp in the above embodiments can be an infrared spotlight or an incandescent light beam.

[0092] Furthermore, in step S03, the postural assessment form is a wall chart with coordinate grids. After the light source is directly irradiated onto the wall chart, by comparing the offset of the light spot position from the standard coordinates, the symmetry deviation of the shoulder and spine is displayed in real time. In the embodiment, when the light source is directly irradiated onto the wall chart, by comparing the offset of the light spot position from the standard coordinates, the symmetry deviation of the shoulder and spine can be displayed in real time. This intuitive display method makes the evaluation result easier to understand and accept.

[0093] In addition, a speaker is integrated on the circuit board. The purpose is that the method provided in this embodiment also includes a real-time training correction step, the light source is reversed 180 degrees to directly face forward, and the subject adjusts the posture according to the standard points of the posture assessment table in front. When the deviation exceeds the threshold, a reminder is given through sound. The so-called reminder is to explain the difference between the value of the shoulder tilt and the preset threshold, specifically the data of the left and right shoulder tilt.

[0094] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
