Description

Technical Field

[0001] This utility model relates to the field of shoulder and neck rehabilitation technology, specifically to a shoulder and neck rehabilitation assistive device for elderly patients with cerebrovascular disease. Background Technology

[0002] In the rehabilitation training of elderly patients with hemiplegia due to cerebrovascular disease, the control ability of the core muscle groups such as the anterior and posterior deltoids and latissimus dorsi in the shoulder and neck area is crucial for the walking arm swing function. It not only requires the maintenance of single joint range of motion, but also depends on the symmetrical and coordinated contraction of bilateral muscle groups in alternating arm swing.

[0003] Existing rehabilitation equipment generally fails to adequately simulate the muscle force characteristics during natural arm swing when training the shoulder and neck muscles. Traditional training methods are unable to activate the alternating contraction rhythm of bilateral muscles, leading to disuse atrophy or abnormal spasms in the shoulder and neck muscles on the hemiplegic side due to lack of regular stimulation, while the muscles on the healthy side may suffer from overcompensation and strain. Utility Model Content

[0004] The purpose of this invention is to provide a shoulder and neck rehabilitation aid for elderly patients with cerebrovascular disease, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoulder and neck rehabilitation aid for elderly patients with cerebrovascular disease, comprising a base plate, two support rods fixedly connected to the upper end of the base plate, a joint swing assembly provided at the upper end of the two support rods, and a drive assembly provided on one side of the joint swing assembly; The joint swing assembly includes a support frame fixedly connected to the upper ends of the two support rods, a storage slot opened at the lower end of the support frame, two transmission rods rotatably connected in the storage slot, a traction plate fixedly connected to the opposite side of the two transmission rods, and a return spring fixedly connected to the side of the storage slot near the two transmission rods, with the other end of the return spring fixedly connected to the two transmission rods respectively. The drive assembly includes a dual-motor fixedly connected to one side of the support frame, and eccentric wheels are fixedly connected to both output ends of the dual-motor. The drive assembly also includes two limiting frames fixedly connected to the lower end of the support frame. Each of the two limiting frames has a pressing rod slidably connected to its lower end. Each pressing rod has a pressing block fixedly connected to one end and a wear-resistant plate fixedly connected to the other end.

[0006] Preferably, the support frame is a C-shaped aluminum alloy frame structure with the opening facing outwards from the patient's body, and the inner curvature of the frame matches the contour of the human shoulder.

[0007] Preferably, the return spring has an arc-shaped structure design, with its center coinciding with the rotation axis of the transmission rod. The arc deformation direction of the return spring is consistent with the physiological trajectory of shoulder joint flexion and extension. The elastic coefficient of the return spring is 2N / cm-6N / cm.

[0008] Preferably, the two eccentric wheels at the output end of the dual-path motor are staggered at 180°.

[0009] Preferably, the extrusion rod has a rectangular hollow structure design.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the asynchronous swing design of the eccentric wheel driven by dual motors, it can accurately simulate the alternating activation pattern of the shoulder and neck muscles on both sides during walking, so that the anterior deltoid and latissimus dorsi muscles can obtain symmetrical and regular contraction stimulation during the forward and backward arm swing, effectively improving the nerve recruitment ability and bilateral synergy of the muscles on the hemiplegic side.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: Example 1: A shoulder and neck rehabilitation aid for elderly patients with cerebrovascular disease, including a base plate 1, with two support rods 2 fixedly connected to the upper end of the base plate 1, and a joint swing assembly provided at the upper end of the two support rods 2, with a drive assembly provided on one side of the joint swing assembly; The joint swing assembly includes a support frame 3 fixedly connected to the upper end of two support rods 2, a storage groove 4 opened at the lower end of the support frame 3, two transmission rods 5 rotatably connected in the storage groove 4, a traction plate 6 fixedly connected to the opposite side of the two transmission rods 5, and a return spring 7 fixedly connected to the side of the storage groove 4 near the two transmission rods 5, and the other end of the return spring 7 fixedly connected to the two transmission rods 5 respectively. The drive assembly includes a dual-motor 8 fixedly connected to one side of the support frame 3, and eccentric wheels 9 are fixedly connected to both output ends of the dual-motor 8. The drive assembly also includes two limiting frames 10 fixedly connected to the lower end of the support frame 3. Each of the two limiting frames 10 has a pressing rod 11 slidably connected to its lower end. Each pressing rod 11 has a pressing block 12 fixedly connected to one end and a wear-resistant plate 13 fixedly connected to the other end.

[0015] During use, the patient stands in front of the device, aligning their shoulder with the center of the support frame 3, placing the arm on the training side inside the traction plate 6 with the hand hanging naturally. The dual-path motor 8 is activated, and its output drives the eccentric wheel 9 to rotate. The eccentric wheel 9 then compresses the wear-resistant plate 13, which in turn drives the compression rod 11 to reciprocate linearly within the limiting frame 10. The moving compression rod 11 then compresses the transmission rod 5 through the compression block 12. The compressed transmission rod 5 then swings around the axis at the connection point. When the transmission rod 5 swings, it stretches the return spring 7, which in turn extends the shoulder joint, simulating natural arm swing. Repeated training activates proprioception in the shoulder and neck muscles.

[0016] Example 2: This example differs from Example 1 in that the support frame 3 is a C-shaped aluminum alloy frame structure with the opening facing the outside of the patient's body. The inner curvature of the frame matches the contour of the human shoulder. The reset spring 7 has an arc-shaped structure design, with its center coinciding with the rotation axis of the transmission rod 5. The arc deformation direction of the reset spring 7 is consistent with the physiological trajectory of shoulder flexion and extension. The elastic coefficient of the reset spring 7 is 2N / cm-6N / cm. The two eccentric wheels 9 at the output end of the dual-channel motor 8 are staggered at 180°. The compression rod 11 has a rectangular hollow structure design.

[0017] During use, the ergonomic design of the C-shaped support frame 3 allows the open side to be aligned with the patient's outer shoulder, ensuring the inner curve of the support frame 3 conforms to the shoulder contour and improving stability during training. The dual-motor 8 drives two 180° staggered eccentric wheels 9 to rotate asynchronously, causing the transmission rods 5 on both sides to swing alternately. The patient can train both shoulders simultaneously. The rectangular hollow compression rod 11 reduces the weight of the components. When the transmission rod 5 flexes or extends to its limit, the arc deformation direction of the return spring 7 is consistent with the physiological trajectory of the shoulder joint. The patient follows the swing rhythm of the transmission rod 5, strengthening the symmetrical control of the anterior and posterior deltoids and latissimus dorsi muscles, and inhibiting compensatory movements such as shrugging. After training, the motor is turned off, and the return spring 7 drives the transmission rod 5 to return to its original position. The open design of the C-shaped support frame 3 allows the patient to quickly remove themselves from the device, making it suitable for home or rehabilitation institution use.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
