Description

Technical Field

[0001] The invention relates to the technical field of medical detection equipment, in particular to a child growth and development detection device. Background Art

[0002] Scoliosis, also known as scoliosis, is a three-dimensional deformity of the spine, including abnormal sequences in the coronal, sagittal and axial positions. The normal spine is arranged in a relatively straight vertical line, and the two sides of the trunk are symmetrical. If there are abnormal postures such as uneven shoulders, positive flexion test, trunk rotation, asymmetric back, high and low pelvis, it should be suspected whether there is a "scoliosis" disease. Early detection, early intervention and early treatment are the key to preventing adolescent scoliosis. The scoliosis measuring ruler commonly used in clinical practice collects data on the cone rotation angle of scoliosis patients by applying gravity to the ball.

[0003] Existing equipment has the following disadvantages: the traditional scoliosis ruler requires the user to take off clothes when operating it, and the person being measured needs to stand upright with feet hip-width apart and hands hanging naturally. The ruler is placed on the spine and then the ruler is slid down as the child bends over to measure the scoliosis of the spine. However, the traditional scoliosis ruler is difficult to balance and fix with the spine, and is prone to swing left and right during measurement, resulting in inaccurate measurement results. It is still necessary to take anteroposterior and lateral spinal radiographs to make a clear diagnosis.

[0004] Therefore, the present application now proposes a child growth and development detection device to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a child growth and development detection device to solve the above-mentioned problem that the measurement is prone to fluctuations, resulting in inaccurate measurement results.

[0006] To achieve the above object, the present invention provides the following technical solution: a child growth and development detection device, comprising a measuring ruler body and a placement slot provided in the middle of the lower end of the measuring ruler body, and further comprising:

[0007] A support unit, symmetrically arranged inside the placement slot, for supporting the spine of the user;

[0008] A detection unit, disposed at the lower part of the measuring ruler body and connected to the support unit, for detecting the accuracy of the displacement of the support unit;

[0009] The limiting unit is arranged inside the measuring ruler body and connected to the supporting unit, and is used for limiting the left-right deviation of the measuring ruler body.

[0010] The lower end of the measuring ruler body is provided with a mounting groove for placing the limiting unit, and the lower end of the measuring ruler body is provided with a base frame, and the base frame is provided with a moving groove for the limiting unit to move at a position corresponding to the limiting unit.

[0011] Wherein, the support unit includes a support column inserted through the base frame, a top block arranged on the side of the support column located inside the installation groove, and a bottom plate arranged on the side of the support column located inside the placement groove, and the support column is located between the bottom plate and the base frame and is sleeved with a first elastic member.

[0012] Wherein, the detection unit includes a guide rail fixed on the upper end of the base frame, a slider slidably arranged on the guide rail and a detection plate rotatably arranged on the slider, and arc plates expanding downward are arranged on both sides of the detection plate, and the lower end of the arc plate abuts against the base plate.

[0013] Wherein, a sliding groove is provided at a position of the sliding block corresponding to the guide rail, a fixing column is fixed on a side of the sliding block away from the guide rail, and the detection plate is rotatably sleeved on the fixing column.

[0014] A positioning pin is fixed on a side of the fixing column away from the sliding block, and a detection pin is arranged on the detection plate at a position corresponding to the positioning pin.

[0015] Wherein, the limiting unit includes a fixed shaft fixed inside the installation groove, a guide box sleeved on the fixed shaft, and a connecting plate arranged on the guide box and inclined at one side close to the placement groove, and the connecting plate abuts against the top block.

[0016] Wherein, a second elastic member is arranged on a side of the guide box away from the connecting plate, and the second elastic member is arranged obliquely and an upper end of the second elastic member is fixed on the mounting groove.

[0017] Wherein, a ball is arranged inside the guide box, a rolling groove for placing the ball is opened inside the guide box, a sealing plate is detachably fixed to the lower end of the guide box, and the ball protrudes outward from the sealing plate.

[0018] The front end of the measuring ruler body is provided with an arc-shaped detection groove, the detection groove is symmetrically arranged about the center of the measuring ruler body, and detection beads are arranged inside the detection groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The measured person of the present invention needs to stand upright with his feet as wide as the hips and his hands hanging naturally. The measuring ruler body is placed on the measured person's spine. The support unit supports both sides of the measured person's spine. When the measuring ruler body is in contact with the measured person's skin, the support unit and the measured person's spine are squeezed, driving the limiting unit to rotate on the measuring ruler body, so that the limiting unit limits the moving position of the measuring ruler body, and then the measuring ruler body is slid down with the child bending over to measure the scoliosis of the spine. The detection unit can detect whether the measuring ruler body is lateralized during the movement of the measuring ruler body, and can timely detect whether the measuring ruler body is tilted left and right at the measured person's spine. The limiting unit can better fit the measured person's skin, reduce the amplitude of the left and right tilt of the measuring ruler body when the measured person is measuring, thereby improving the accuracy of the spinal curvature measurement results, and can accurately detect the support condition of the child's spine and the accuracy of the displacement, so as to more accurately evaluate the child's growth and development status, especially spinal health.

[0021] 2. The fixed column of the present invention is fixed at the center position of the slider, and the detection plate can rotate along the fixed column, so that the offset position of the measuring ruler body can be adjusted according to the deflection angle of the detection plate on the fixed column. When the bottom plate on the left side tilts to the right side, the bottom plate on the left side has more contact with the spine. Since the position in the middle of the spine gradually increases, the position of the bottom plate on the left side will be higher than that of the bottom plate on the right side. At this time, the detection plate rotates counterclockwise on the fixed column, so the measuring ruler body needs to be moved to the left side. When the bottom plate on the right side tilts to the left side, the bottom plate on the right side has more contact with the spine. Since the position in the middle of the spine gradually increases, the position of the bottom plate on the right side will be higher than that of the bottom plate on the left side. At this time, the detection plate rotates clockwise on the fixed column, and the measuring ruler body needs to be moved to the right side. The offset state of the measuring ruler body can be detected in time, and timely correction can be made to ensure the accuracy of the measurement result. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The present invention provides a technical solution: a child growth and development detection device, comprising a measuring ruler body 1 and a placement slot 14 provided in the middle of the lower end of the measuring ruler body 1, and further comprising:

[0030] The support unit 2 is symmetrically arranged inside the placement slot 14 and is used to support the spine of the user;

[0031] The detection unit 3 is arranged at the lower part of the measuring ruler body 1 and connected to the support unit 2, and is used to detect the accuracy of the displacement of the support unit 2;

[0032] The limiting unit 4 is arranged inside the measuring ruler body 1 and connected to the supporting unit 2 , and is used for limiting the left-right deviation of the measuring ruler body 1 .

[0033] It should be noted that, when working, the person being measured needs to stand upright with his feet as wide as the hips and his hands hanging naturally. The measuring ruler body 1 is placed on the spine of the person being measured, and the support unit 2 supports both sides of the spine of the person being measured. When the measuring ruler body 1 is in contact with the skin of the person being measured, the support unit 2 and the spine of the person being measured are squeezed, driving the limiting unit 4 to rotate on the measuring ruler body 1, so that the limiting unit 4 limits the moving position of the measuring ruler body 1, and then the measuring ruler body 1 is slid down with the child bending over to measure the scoliosis of the spine. The detection unit 3 can detect whether the measuring ruler body 1 is lateralized during the movement of the measuring ruler body 1, and can timely detect whether the measuring ruler body 1 is tilted left and right at the spine of the person being measured, and the limiting unit 4 can better fit the skin of the person being measured, reducing the amplitude of the left and right tilt of the measuring ruler body 1 when the person being measured is measuring, thereby improving the accuracy of the spinal curvature measurement results, and can accurately detect the support condition of the child's spine and the accuracy of the displacement, so as to more accurately evaluate the child's growth and development status, especially spinal health.

[0034] In one embodiment, a mounting groove 13 for placing the limiting unit 4 is provided at the lower end of the measuring ruler body 1 , a base frame 15 is provided at the lower end of the measuring ruler body 1 , and a moving groove 151 for the limiting unit 4 to move is provided at the position of the base frame 15 corresponding to the limiting unit 4 .

[0035] This design, see Figure 3 ,as well as Figure 6 When the support unit 2 squeezes the limiting unit 4, the limiting unit 4 rotates inside the moving groove 151, and then rotates out from the inside of the base 15, contacts the skin of the person being measured, and squeezes the skin of the person being measured inward, thereby reducing the amplitude of the left and right movement of the measuring ruler body 1 when sliding on the spine, which can more accurately reflect the scoliosis of the spine and provide a reliable diagnosis basis for medical personnel.

[0036] In one embodiment, the support unit 2 includes a support column 22 that is inserted through the base frame 15 and is obliquely arranged, a top block 24 that is arranged on the side of the support column 22 located inside the mounting groove 13, and a bottom plate 21 that is arranged on the side of the support column 22 located inside the placement groove 14. The support column 22 is located between the bottom plate 21 and the base frame 15 and is sleeved with a first elastic member 23. The first elastic member 23 is made of a damped spring or elastic pad, which can drive the bottom plate 21 to perform a reset movement. The support column 22 is symmetrical about the center of the measuring ruler body 1 and is arranged to expand upward.

[0037] This design, see Figure 1-6When the measuring ruler body 1 is placed on the spine of the person being measured, the bottom plate 21 first contacts the two sides of the spine of the person being measured, and then when the measuring ruler body 1 is pressed down to contact the skin of the person being measured, the bottom plate 21 moves up, driving the support column 22 to move up, and then the top block 24 moves up inside the installation groove 13, and the top block 24 pushes the limiting unit 4 to extend out from the inside of the moving groove 151.

[0038] In one embodiment, the detection unit 3 includes a guide rail 31 fixed to the upper end of the base frame 15, a slider 32 slidably arranged on the guide rail 31, and a detection plate 34 rotatably arranged on the slider 32. The detection plate 34 is provided with arc plates 35 that expand downward on both sides, and the lower end of the arc plate 35 abuts against the bottom plate 21.

[0039] This design, see Figure 4-6 In the process of moving on the bottom plate 21, the slider 32 will be pushed to move up on the guide rail 31. When one of the bottom plates 21 tilts to the left or right sides of the spine, the bottom plate 21 will drive the detection plate 34 to rotate along the center of the slider 32, so that the measuring ruler body 1 can be offset in time and corrected in time to ensure the accuracy of the measurement result.

[0040] In one embodiment, a slide groove 321 is provided at a position of the slider 32 corresponding to the guide rail 31 , a fixing column 33 is fixed to a side of the slider 32 away from the guide rail 31 , and the detection plate 34 is rotatably sleeved on the fixing column 33 .

[0041] This design, see Figure 4-6 The fixed column 33 is fixed at the center position of the slider 32, and the detection plate 34 can rotate along the fixed column 33, so that the offset position of the measuring ruler body 1 can be adjusted according to the deflection angle of the detection plate 34 on the fixed column 33. When the bottom plate 21 on the left side tilts to the right side, the bottom plate 21 on the left side contacts more with the spine. Since the position in the middle of the spine gradually increases, the position of the bottom plate 21 on the left side will be higher than that of the bottom plate 21 on the right side. At this time, the detection plate 34 rotates counterclockwise on the fixed column 33, so it is necessary to move the measuring ruler body 1 to the left side. When the bottom plate 21 on the right side tilts to the left side, the bottom plate 21 on the right side contacts more with the spine. Since the position in the middle of the spine gradually increases, the position of the bottom plate 21 on the right side will be higher than that of the bottom plate 21 on the left side. At this time, the detection plate 34 rotates clockwise on the fixed column 33, and it is necessary to move the measuring ruler body 1 to the right side, so that the offset state of the measuring ruler body 1 can be detected in time and adjusted.

[0042] In one embodiment, a positioning pin 331 is fixed to a side of the fixing column 33 away from the sliding block 32 , and a detection pin 341 is disposed at a position of the detection plate 34 corresponding to the positioning pin 331 .

[0043] This design, see Figure 4When the detection pin 341 is aligned with the positioning pin 331 under normal circumstances, when the detection plate 34 deflects, the detection pin 341 and the positioning pin 331 are misaligned, which can facilitate observation of the offset of the detection plate 34 and then make timely adjustments.

[0044] In one embodiment, the limiting unit 4 includes a fixed shaft 42 fixed inside the installation groove 13, a guide box 41 sleeved on the fixed shaft 42, and a connecting plate 43 arranged obliquely on the side of the guide box 41 close to the placement groove 14, and the connecting plate 43 abuts against the top block 24.

[0045] This design, see Figure 3-6 The top block 24 moves upward to push the connecting plate 43 to rotate along the fixed axis 42, and then the guide box 41 extends from the inside of the measuring ruler body 1 and squeezes toward the middle of the placement groove 14. When the measuring ruler body 1 moves slightly left and right at the patient's spine during the detection process, the degree of deviation can be limited to maintain the stability of the device, thereby improving the accuracy of the measurement result.

[0046] In one embodiment, a second elastic member 44 is provided on one side of the guide box 41 away from the connecting plate 43. The second elastic member 44 is tilted and the upper end is fixed on the mounting groove 13. The second elastic member 44 is made of a damped spring or elastic pad.

[0047] This design, see Figure 5 ,as well as Figure 6 When the guide box 41 extends from the inside of the installation groove 13, the second elastic member 44 is stretched. When the device is used, the second elastic member 44 drives the guide box 41 to return to its original position, so that the entire device can be easily stored in place.

[0048] In one embodiment, a ball 45 is disposed inside the guide box 41 , a rolling groove 46 for accommodating the ball 45 is opened inside the guide box 41 , a sealing plate 47 is detachably fixed to the lower end of the guide box 41 , and the ball 45 protrudes outward from the sealing plate 47 .

[0049] This design, see Figure 3 ,as well as Figure 5-6 When the guide box 41 contacts the skin of the person being measured, the ball 45 contacts the patient's skin. When the guide box 41 slides on the spine, the ball 45 rolls on the patient's skin, which can reduce the friction between the guide box 41 and the patient's skin, making the person being measured feel more comfortable during the detection process and improving the overall user experience.

[0050] In one embodiment, an arc-shaped detection groove 11 is provided at the front end of the measuring ruler body 1 . The detection groove 11 is symmetrically arranged about the center of the measuring ruler body 1 . A detection bead 12 is arranged inside the detection groove 11 .

[0051] This design, see Figure 1 ,as well as Figure 2 When the measuring ruler body 1 detects that the person's spine has scoliosis, the measuring ruler body 1 tilts, and the detection bead 12 moves inside the detection groove 11 toward the side of the spinal curvature. Then, the alignment of the scale lines on the outside of the detection groove 11 of the detection bead 12 can be observed to detect the scoliosis of the person's spine.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying the importance of the relative description or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
