Description

Technical Field

[0001] This invention belongs to the technical field of shoulder periarthritis rehabilitation training equipment, specifically referring to a home rehabilitation exercise device for patients with shoulder periarthritis. Background Technology

[0002] Frozen shoulder, also known as adhesive capsulitis or shoulder pain syndrome, is a common shoulder condition. It is usually caused by inflammation or injury to the muscles, tendons, or bursae around the shoulder. Frozen shoulder can lead to limited range of motion in the shoulder joint, causing pain and discomfort.

[0003] Rehabilitation training for frozen shoulder is an important part of restoring shoulder function and reducing pain. Training methods include shoulder mobility exercises, muscle strengthening exercises, balance exercises, and stretching and flexibility exercises. Shoulder mobility exercises, in particular, aim to restore the normal range of motion of the shoulder through a series of movements. These may include rotational movements, elevation, abduction, and induction. However, these training methods require medical staff to provide rotational force to the patient's arm, which is labor-intensive, and the kinetic energy released during abduction movements is not fully utilized.

[0004] Existing rehabilitation training for patients with frozen shoulder is labor-intensive and results in high energy consumption for patients. At the same time, the muscles around the shoulder do not receive proper relaxation and massage during training. Therefore, it is necessary to design a rehabilitation training device that can convert kinetic energy and massage and relax the muscles. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a home rehabilitation exercise device for patients with frozen shoulder, which effectively improves the energy utilization efficiency of rehabilitation equipment, realizes automatic limitation of the arm's spatial range, and can selectively adjust the diameter range of rotation training, so as to fully ensure the design effect of patients exercising their shoulders at home.

[0020] This solution provides a home rehabilitation exercise device for patients with frozen shoulder, which has the following beneficial effects: (1) Through the gear combination structure, in conjunction with torsion springs and other equipment, the kinetic energy generated by the abduction of the left arm is converted into the kinetic energy of the reciprocating rotation of the massage ball, so as to realize the design effect of abduction of the left arm and rotational massage of the right shoulder, and make full use of the patient's energy; (2) By using the deflection kinetic energy generated during the contact between the arm contact plate and the external extension plate, the deflection arc plate can be automatically rotated during the process of the patient's arm being placed into the fixed arc plate, and the arm can be restricted in a closed space, thus avoiding the design problem that the patient still needs to fix their own arm. (3) Using the ball head structure for interlocking connection can better enable the arm to perform rehabilitation training in different rotation ranges. Attached Figure Description

[0037] like Figure 7 , Figure 12 As shown, the automatic arm limiting device 26 includes a fixed arc plate 34, a deflection arc plate 35, a deflection slot 36, an arm contact plate 37, a contact plate slide groove 38, a limiting block 39, an adjusting rod 40, a rod locking block 41, a rod slide groove 42, and an external extension plate 43. The fixed arc plate 34 is fixedly connected to the ball head bracket 33. The deflection slot 36 is disposed on the fixed arc plate 34, and the deflection arc plate 35 is engaged and rotatably disposed on the deflection slot 36. The contact plate slide groove 38 penetrates the fixed arc plate 34. The upper wall of the shaped plate 34 has an arm contact plate 37 that is engaged and slidably mounted on the contact plate groove 38. A limiting block 39 is fixedly mounted on the side wall of the arm contact plate 37. A pull rod groove 42 is connected to the contact plate groove 38.

[0038] like Figure 7 , Figure 12 As shown, the deflection arc plate 35 and the deflection slot 36 are connected by a torsion spring, the arm contact plate 37 and the upper wall of the fixed arc plate 34 are fixedly connected by a spring, the limiting block 39 and the pull rod block 41 are in contact and connected, the pull rod slide 42 and the adjusting pull rod 40 are connected by a spring, the limiting block 39 is set as a right-angled triangular prism structure, and the pull rod block 41 is set as a right-angled triangular prism structure.

[0039] like Figure 3 , Figure 4As shown, there are two sets of automatic arm limiting devices 26, and the two sets of automatic arm limiting devices 26 are respectively fixed at both ends of the arc-shaped bracket 28.

[0040] In practical use, the person stands on the support plate 1, facing away from the upper shoulder sleeve 9, and places their right shoulder into the upper shoulder sleeve 9. The strap 10 passes through the turning rod 12 on the turning groove 11 from the inside, so that the two sets of patches 13 fit together, thereby limiting the patient's right shoulder. When the patient raises their arm, it comes into contact with the arm contact plate 37 as it enters the two sets of fixed arc plates 34. During the compression of the arm contact plate 37, the arm contact plate 37 slides upward along the contact plate slide groove 38, and the limiting block 39 slides upward along the inclined surface of the pull rod block 41. During this process... The limiting block 39 presses and pushes the adjusting rod 40 to move laterally until the arm contact plate 37 collides with the outer extension plate 43, forcing the outer extension plate 43 to drive the deflection arc plate 35 to deflect, and forming a closed ring structure with the fixed arc plate 34 and the deflection arc plate 35 to fix the arm; after the arm is fixed, the rotating disk 44 is rotated. Since the arm is fixed on the automatic arm limiting device 26, and the lateral slide rod 46 is fixedly connected to the automatic arm limiting device 26 through the arc bracket 28, the patient's arm makes a circular motion as a whole; the right arm rotates... During the exercise, the left hand pulls the pull ring 14 to perform an abduction movement of the left shoulder. As the pull ring 14 is pulled, the rope 15 moves back and forth within the rope groove 16. The rope roller 17 rotates back and forth under the action of the torsion spring and the rope 15. The rotation of the rope roller 17 drives the main gear 19 to rotate, thereby transferring the rotational kinetic energy to the massage ball 24 through multiple gear structures. This achieves the design effect of simultaneously massaging the patient's right shoulder and performing abduction training on the left shoulder. Depending on the different stages of symptoms in patients with frozen shoulder, the radius of the arm rotation exercise needs to be adjusted. Pull the lifting plate 51 in the opposite direction to the lateral adjustment slide 45, so that the lateral slide rod 46 separates from the limiting plate 48. Then, move the lateral adjustment slide 45 laterally to adjust the spatial position of the lateral slide rod 46, and at the same time adjust the position of the single-sided telescopic bracket 53 on the telescopic bracket lateral sliding slide 54. During the arm rotation training, the small spring 30 is stretched and deformed in the ball head groove bushing 29. At the same time, the included angle between the ball head groove bushing 29, the ball head groove bracket 31, the ball head bracket one 32 and the ball head bracket two 33 and the horizontal plane also changes.
