Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a spinal mobility measuring device for ankylosing spondylitis. Background Art

[0002] Ankylosing spondylitis is a chronic progressive inflammatory disease that primarily affects the spine and may involve the sacroiliac joints and surrounding joints to varying degrees.

[0003] In terms of etiology, it is closely related to genetic factors (such as the HLA-B27 gene), and environmental factors may also induce it. In terms of symptoms, low back pain or stiffness is common in the early stage, especially in the morning after sitting or lying for a long time, and can be relieved after activity. As the disease progresses, the range of motion of the spine will gradually be limited, and in severe cases, spinal deformities may occur, such as "bamboo-like" changes. It may also affect peripheral joints such as the hip and knee joints, causing pain and swelling. This disease is more common in young men, and the age of onset is usually between 13 and 31 years old. Although it cannot be completely cured at present, comprehensive measures such as drug treatment (such as non-steroidal anti-inflammatory drugs, anti-rheumatic drugs, etc.), physical therapy (such as hot compresses, massage) and functional exercise can effectively control symptoms, delay disease progression, and help patients maintain a better quality of life.

[0004] When measuring the range of motion of the spine for ankylosing spondylitis, the cooperation of the patient is required, and the Schober test needs to be checked, that is, measuring the distance between the midpoint of the line connecting the bilateral posterior superior iliac spines and 10 cm upward when standing upright, as well as the distance when bending over to the maximum forward flexion of the spine, to evaluate the mobility of the spine. In addition, the scoliosis of the spine will also be checked. In the prior art, the measurement of spinal mobility is usually performed directly by medical staff using a protractor and a ruler. However, such an operation has the following technical problems: 1. Because manual measurement by medical staff takes time, patients need to cooperate in maintaining bending, lateral flexion, backward bending and rotation for a long time, which increases the burden on patients and prolongs the examination time; 2. Due to the patient's cooperation and the doctor's need to use tools to measure at the same time during the examination, the patient needs to perform the examination repeatedly;

[0005] Therefore, there is a need to provide a spinal mobility measurement device for ankylosing spondylitis that can be adapted to patients of different heights and body shapes and can quickly perform measurements and obtain accurate data. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a spinal mobility measuring device for ankylosing spondylitis. The measuring device is designed based on the convenience of use and the rapid measurement structure. The back sleeve mechanism and the support rod can quickly adapt to the backs of patients of different heights. The spinal movement drives the back sleeve mechanism to rotate in multiple directions, and records the angles in each direction when the spine rotates, so as to complete the measurement of spinal mobility.

[0007] In order to achieve the above technical objectives, the present invention is implemented by the following technical solutions:

[0013] Furthermore, a mounting tube is fixedly connected to the top of the support rod, and a notch is provided in the middle of the mounting tube; the rotating shaft is rotatably sleeved in the mounting tube, and the shaft hole is located above the middle of the mounting tube; angle scales B arranged in a circumferential direction are provided on both sides of the notch, and indicator marks B pointing to the angle scales B are provided on the outer surfaces of both sides of the connecting block, and after the connecting block is rotated relative to the support rod, the angle of rotation of the connecting block is obtained by reading the angle data of the indicator mark B pointing to the angle scale B;

[0014] Furthermore, a rotating shaft that overhangs outward and matches the shaft hole is fixedly connected to the bottom end surface of the telescopic plate; angle scales C are arranged on the end surfaces at both ends of the shaft hole; an indicator mark C pointing to the angle scale C is arranged on the end surface of the rotating shaft and the end surface of the connecting plate opposite to the rotating shaft. After the telescopic plate rotates relative to the connecting block, the angle data of the indicator mark C pointing to the angle scale C is read to obtain the rotation angle of the back sleeve mechanism;

[0015] Furthermore, the top of the telescopic plate is fixedly connected with a mounting seat, the mounting seat is a horizontal tubular structure, and forms a nearly T-shaped structure with the telescopic plate; the driving gear is rotatably mounted in the middle of the mounting seat; the two driving racks are both connected to the mounting seat, and the ends that are far away from each other pass through the mounting seat;

[0016] Furthermore, the restraint belt includes one or more of an elastic belt, a snap-on belt, and a Velcro belt;

[0017] Furthermore, the planes where the angle scale B and the angle scale C are located are both vertical planes and are perpendicular to each other, and are both perpendicular to the plane where the angle scale A is located;

[0020] The connecting block divides the overall lifting and lowering of the back sleeve mechanism of the device into the extension and retraction of the support rod and the extension and retraction of the retractable plate, so that it can adapt to patients with different bilateral iliac heights and patients with different upper body lengths;
