Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an upper limb strength rehabilitation training and correction device. Background Art

[0002] With the continuous advancement of medical technology, rehabilitation therapy has gradually developed into an independent clinical discipline and an important technical means to promote the recovery of patients' physical and mental functions. Its core goal is to help patients maximize their ability to resume daily life, study, work, and social interaction, thereby enabling them to reintegrate into society and improve their quality of life.

[0003] Among the rehabilitation population, a significant proportion suffer from upper limb motor dysfunction caused by cerebrovascular disease, brain trauma, or other neurological diseases. These patients often experience weakened muscle strength, joint stiffness, muscle spasms, decreased coordination, and other problems, which seriously affect their ability to live daily lives. Scientific and effective upper limb rehabilitation training for this population can not only improve muscle spasticity and delay or prevent muscle and joint atrophy, but also enhance upper limb strength, promote neuromuscular function reconstruction, and help alleviate shoulder and back pain caused by insufficient exercise.

[0004] However, existing upper limb rehabilitation training devices generally focus on passive movement, using external forces to drive the patient's upper limbs to complete the exercise process. This results in low patient participation and fails to effectively stimulate their willingness to exercise independently and their neuromuscular ability to actively participate. Furthermore, traditional devices are relatively simple in function and lack diverse training modes, making it difficult to provide personalized training plans based on different rehabilitation stages or individual circumstances. Furthermore, current rehabilitation devices generally suffer from complex structures, bulky sizes, and inconvenient operation. Furthermore, the high manufacturing and maintenance costs increase the overall cost of use, further hindering the popularization and application of rehabilitation training devices in primary healthcare institutions or home rehabilitation.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figure 1-Figure 7 The present invention provides an upper limb strength rehabilitation training correction device, comprising: A rehabilitation table 1, wherein the bottom of the rehabilitation table 1 is provided with a lifting and adjusting component; A rehabilitation exercise platform 2 is slidably mounted on the top surface of the rehabilitation table 1. A mounting bracket 3 is provided on the top surface of the rehabilitation exercise platform 2. A rotating shaft 4 is rotatably mounted on the mounting bracket 3. The upper limb training mechanism includes a first connecting rod 5, a second connecting rod 6 and two U-shaped gripping arms 7. The first connecting rod 5 is arranged on the rotating shaft 4. A fixing groove 8 is opened on the top surface of the middle part of the first connecting rod 5. A fixing bolt 9 that is threaded and matched with the fixing groove 8 is passed through the top surface of the rotating shaft 4. Both ends of the first connecting rod 5 are threadedly connected with stud bolts 10. The second connecting rod 6 is located above the first connecting rod 5. One end of the two U-shaped gripping arms 7 can be rotatably arranged on the two ends of the second connecting rod 6, and the other end is sleeved with a first connecting nut 11 that is threadedly matched with the stud bolt 10. The driving module includes an L-shaped flip seat 12 and a servo motor 13 installed on the L-shaped flip seat 12. The L-shaped flip seat 12 can be rotatably installed on the rehabilitation table 1. The rehabilitation table 1 is provided with fixing components for fixing the position of the L-shaped flip seat 12 on both sides of the rotation position of the L-shaped flip seat 12. A driving gear 14 is sleeved on the output shaft of the servo motor 13, and a rack 15 that cooperates with the driving gear 14 is provided on the rehabilitation motion platform 2.

[0023] The upper limb strength rehabilitation training and correction device mainly consists of a rehabilitation table 1, a rehabilitation exercise platform 2, an upper limb training mechanism and a drive module. Its specific working process is as follows: First, the rehabilitation table 1 serves as the supporting base of the overall structure, and its bottom is equipped with a lifting and adjusting component, which can be used to adjust the overall height of the device, so as to adapt to patients of different heights or postures, and improve the comfort and convenience of training. Before use, the first connecting rod 5 is passed through the rotating shaft 4 installed on the mounting bracket 3, and the fixing bolt 9 is tightened and screwed into the fixing groove 8 on the top surface of the first connecting rod 5, so as to achieve the locking and fixing of the first connecting rod 5 to prevent it from displacement or rotation during training. Subsequently, the stud bolts 10 at both ends of the first connecting rod 5 are threadedly connected to the first connecting nuts 11 on the two U-shaped holding arms 7 at both ends of the second connecting rod 6, thereby completing the assembly and fixation of the upper limb training mechanism. During the rehabilitation training process, different training methods can be selected according to the patient's rehabilitation goals and upper limb functional status at different stages, including: 1. Passive Swing Training: The patient holds the two U-shaped gripping arms 7 in each hand and rotates the L-shaped flip seat 12, causing the drive gear 14 on the output shaft of the servo motor 13 to engage with the rack 15 on the rehabilitation exercise platform 2. The L-shaped flip seat 12 is then fixed in position using a fixing assembly. At this point, the servo motor 13 is activated, causing the drive gear 14 to rotate and move the rack 15, thereby driving the rehabilitation exercise platform 2 to slide on the rehabilitation table 1. The built-in program then enables the rehabilitation exercise platform 2 to reciprocate, thereby driving the patient's upper limbs to complete passive swing training in the left and right directions. This is suitable for patients in early postoperative rehabilitation or those with weak muscle strength. 2. Active Swing Training: The patient grasps the two U-shaped gripping arms 7 with both hands and rotates the L-shaped flip seat 12, disengaging the drive gear 14 on the output shaft of the servo motor 13 from the rack 15 on the rehabilitation platform 2. The L-shaped flip seat 12 is then fixed in place using a fixing assembly. In this position, the rehabilitation platform 2 can slide freely, and the patient can use their own strength to push the rehabilitation platform 2 back and forth on the rehabilitation table 1, thereby achieving active swing training for the upper limbs and helping to improve active muscle control and coordination. 3. Extension and Retraction Coordination Training: The patient grasps the two U-shaped gripping arms 7 with both hands and rotates the L-shaped flip seat 12, causing the drive gear 14 on the output shaft of the servo motor 13 to engage with the rack 15 on the rehabilitation platform 2. The L-shaped flip seat 12 is fixed in position using a fixing assembly, but the servo motor 13 is not activated. The self-locking mechanism of the servo motor 13 maintains the position of the rehabilitation platform 2. At this point, the patient can extend and retract their upper limbs forward and backward, performing exercises such as extension and retraction, thereby improving shoulder and elbow joint motion and joint range of motion. 4. Upper limb rotation coordination training: By adjusting the use form of the upper limb training mechanism, one of the U-shaped gripping arms 7 is no longer connected to the first connecting rod 5, and is rotated to the top of the second connecting rod 6. For specific forms, please refer to Figure 3 At the same time, the rehabilitation exercise platform 2 maintains a stable position through the self-locking mechanism of the servo motor 13. In this state, the patient holds the two U-shaped gripping arms 7 with both hands and relies on his own strength to drive the upper limb training mechanism to rotate clockwise or counterclockwise around the rotating shaft 4, thereby achieving comprehensive coordination training of the upper limbs. It is suitable for the middle and late stages of rehabilitation or for functional improvement needs for joint flexibility disorders.

[0024] Compared with traditional upper limb rehabilitation training devices, this upper limb strength rehabilitation training and correction device has the advantages of simple structure, rich functions and low cost. Through flexible switching of multiple training modes, it can fully adapt to the patients' diverse needs for passive training, active training and coordination training at different stages of rehabilitation, and effectively realize the upper limb strength recovery plan that combines personalization and targeting. Through active training, it effectively enhances the patients' sense of participation and initiative, stimulates their willingness to exercise autonomously and the active participation ability of the neuromuscular system, thereby providing strong support for achieving higher quality functional reconstruction and rehabilitation goals.
