Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a spinal activity measuring device. Background Art

[0002] Ankylosing spondylitis is a common autoimmune disease in rheumatology and immunology, characterized by inflammatory low back pain. The spine may experience limited movement, stiffness and deformity from bottom to top, and eventually become "bamboo-like", leading to joint dysfunction and loss of function. About 2.4% of the population in China suffers from this disease, and ankylosing spondylitis has become one of the main causes of labor force loss and disability.

[0003] The current methods for measuring spinal mobility mainly include tape measure measurement, special tool measurement and Schober test. The existing methods are generally measured by using special tools. For example, the Chinese utility model with publication number CN216907970U discloses "A spinal mobility measuring device", which includes a scale belt, a measuring ruler and a connecting component. The scale belt and the measuring ruler are both flexible structures with scales; the connecting component is fixedly connected to the measuring ruler, and the scale belt is wrapped around the posterior superior iliac spine and fixed on the patient's trunk. The connecting line of the bilateral posterior superior iliac spines is determined by the scale. After the midpoint, the measuring ruler is detachably connected to the scale belt through the connecting component, and the spinal mobility is measured by the scale on the measuring ruler. The scale belt is wrapped around the posterior superior iliac spine and fixed, and then the scale on the scale belt is used to measure and adjust the scale starting point to the midpoint of the two posterior superior iliac spines, and then the measuring ruler is detachably connected to complete the spinal mobility inspection through the measuring ruler. This structure fixes the measuring ruler and other tools when in use, and adopts a soft structure that fits the human body better, increases the accuracy of measurement, and has a simple structure. All parts of the structure are made of bendable materials, which is easy to carry;

[0004] Although the above-mentioned spinal mobility measurement device has certain advantages in portability, it has a single effect on the measurement of spinal mobility, is not convenient for measuring the patient's left and right scoliosis data, and has many manual operation steps, making the measurement inconvenient.
