Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical testing equipment, and particularly to an upper limb proprioception testing device. Background Art
[0002] With the continuous deepening of people's understanding of upper limb proprioception and its importance in clinical diagnosis and treatment, how to effectively evaluate upper limb proprioceptive function has become a research hotspot in clinical medicine. Especially in the fields of scoliosis, neurological diseases, and sports injuries, doctors and therapists usually need to use equipment to quantitatively evaluate the proprioception of patients, so as to formulate personalized treatment plans. However, there are still certain deficiencies in the existing testing methods for upper limb proprioception.
[0003] Currently, most common testing methods for upper limb proprioception rely on simple clinical observations or traditional visual and tactile evaluations. Although these methods can provide preliminary judgments to a certain extent, they lack scientific quantification tools, and the test results are greatly affected by subjective factors, and there are significant limitations in the repeatability and accuracy of the tests. In addition, most existing equipment fails to fully consider individual differences, especially in cases where there are large physical differences or special physical conditions of patients, and cannot provide highly adaptable and precisely adjustable evaluation means.
[0004] On the one hand, traditional upper limb proprioception testing equipment is often relatively simple in design and difficult to precisely adjust test angles, distances, etc., thus affecting the accuracy of test results. On the other hand, these equipment usually cannot effectively adjust and fix patients of different body types or heights, resulting in limited use in certain specific groups. Therefore, there are still certain deficiencies in the existing technology in meeting clinical needs, improving test accuracy and adaptability.
[0005] More importantly, existing testing methods often lack sufficient dynamic adjustment functions. For example, for a comprehensive evaluation of a patient's upper limb proprioception, factors such as the participant's physique, posture, and test environment must be considered. However, existing devices usually cannot flexibly adjust parameters such as height and angle, resulting in easy generation of errors or patient discomfort during the test. In addition, traditional equipment also has problems of insufficient space in structural design and cannot take into account multiple test conditions, thus affecting the diversity and reliability of the test.

[0041] Specifically, by pulling the rotating handle 302 out of the first fixing block 301 and driving the limit rod 305 to slide inside the rotating rod 303, then rotating the rotating handle 302 to drive the limit rod 305 to rotate, the limit rod 305 drives the rotating rod 303 to rotate, thereby driving the gear 304 to rotate. By the rotation of the gear 304, the rack 306 is driven to move, and the rack 306 drives the first sliding rod 307 to move. The first sliding rod 307 slides on the first fixing block 301 and the first limit block 308. The movement of the first sliding rod 307 is limited by the first limit block 308. By the movement of the first sliding rod 307, the third limit block 701 is driven to move, thereby achieving the effect of height adjustment. By pushing the rotating handle 302 to drive the limit rod 305 to slide inside the rotating rod 303, and then the rotating handle 302 slides inside the first fixing block 301, and then the rotating handle 302 is fixed.
[0042] The lower surface of the first fixing block 301 is fixedly connected to a first connecting block 8. The interior of the first connecting block 8 is slidably connected to the outer wall of a first sliding rod 307. A support rod 4 is rotatably connected inside the first connecting block 8.

[0043] Specifically, by pulling the support rod 4 to rotate on the first connecting block 8 and driving the second fixing block 11 to move, the second fixing block 11 pulls the second connecting rod 10 to move, and the second connecting rod 10 rotates on the second fixing block 11, so that the other end of the second connecting rod 10 rotates on the second connecting block 9 and pulls the second connecting block 9 to move. Furthermore, the unfolding angle of the support rod 4 is limited by the second connecting block 9 and the second connecting rod 10. By pulling the extension rod 12 to slide inside the support rod 4, the effect of overall height adjustment is achieved.
[0044] Working principle: By pulling the support rod 4 to rotate on the first connection block 8 and driving the second fixed block 11 to move, the second fixed block 11 pulls the second connecting rod 10 to move, and the second connecting rod 10 rotates on the second fixed block 11, so that the other end of the second connecting rod 10 rotates on the second connection block 9 and pulls the second connection block 9 to move. Furthermore, the unfolding angle of the support rod 4 is limited by the second connection block 9 and the second connecting rod 10. By pulling the extension rod 12 to slide inside the support rod 4 and pulling the first connecting rod 702 to drive the limit pin 704 to move, the limit pin 704 drives the limit plate 705 to slide inside the third limit block 701, and the limit plate 705 squeezes the second spring 703. When pushing the second limit block 602 to slide inside the third limit block 701, the second spring 703 pushes the limit plate 705 to move, and the limit plate 705 drives the limit pin 704 to slide inside the third limit block 701 and insert into the second limit block 602, thus achieving the effect of fixing the second limit block 602. By pulling the rotating handle 302 out of the first fixed block 301 and driving the limit rod 305 to slide inside the rotating rod 303, and then rotating the rotating handle 302 to drive the limit rod 305 to rotate, the limit rod 305 drives the rotating rod 303 to rotate, thereby driving the gear 304 to rotate. The rotation of the gear 304 drives the rack 306 to move, and the rack 306 drives the first sliding rod 307 to move. The first sliding rod 307 slides on the first fixed block 301 and the first limit block 308. The movement of the first sliding rod 307 is limited by the first limit block 308. The movement of the first sliding rod 307 drives the third limit block 701 to move, thus achieving the effect of height adjustment, so that the upper panel 1 and the lower panel 2 are at the shoulder height of the participant. By pushing the rotating handle 302 to drive the limit rod 305 to slide inside the rotating rod 303, and then the rotating handle 302 slides inside the first fixed block 301, thereby fixing the rotating handle 302. By pulling the lower panel 2 to drive the rotating ring 603 to rotate, the rotating ring 603 rotates on the outer wall of the connecting disc 601, and then the rotating ring 603 squeezes the limit ball head 605, and the limit ball head 605 pushes the second sliding rod 604 to move. The second sliding rod 604 slides inside the connecting disc 601 and squeezes the first spring 606. When the limit groove 607 is aligned with the limit ball head 605, the first spring 606 pushes the second sliding rod 604 to drive the second sliding rod 604 to move, and the second sliding rod 604 inserts into the limit groove 607, thus achieving the effect of limiting the rotating ring 603 and adjusting the angle of the lower panel 2. The participant inserts the index finger into the hole of the lower panel but cannot touch the surface of the upper panel.The effect of testing and evaluating the upper limb proprioception is achieved by observing the postures of the participants.
