Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a myasthenia gravis rehabilitation exercise device. Background Art

[0002] Myasthenia gravis (MG) is an autoimmune disease caused by dysfunction of neuromuscular junction transmission. The main clinical manifestations are partial or systemic skeletal muscle weakness and fatigue. Symptoms worsen after activity and improve after rest. Myasthenia gravis patients often feel soreness and discomfort in the eyes or limbs, or blurred vision, and fatigue in the early stages of the disease. Fatigue worsens in hot weather or during menstruation. As the disease progresses, skeletal muscles become obviously tired and weak. The notable feature is that muscle weakness worsens after fatigue in the afternoon or evening, and improves in the morning or after rest. This phenomenon is called "lighter in the morning and heavier in the evening". Myasthenia gravis requires the use of auxiliary exercise devices during the rehabilitation process. Therefore, it is necessary to design a myasthenia gravis rehabilitation exercise device.

[0003] During the rehabilitation process of myasthenia gravis, most patients are treated with medication, followed by auxiliary training with rehabilitation equipment. However, the internal structure of existing rehabilitation training devices is relatively simple, and they can only provide protective operations for patients during standing and walking exercises, but the auxiliary rehabilitation training effect on the patients themselves is poor. Moreover, they are only suitable for some patients who can walk, and are not convenient for patients with more serious conditions who are not suitable for walking, which reduces the scope of application of the training device in the later stage.

[0024] The resistance exercise function includes a guide rail 2, a rack 3, a spring 17, and a hook 18. The guide rail 2 is located in the middle of the top of the base plate 1. The rack 3 is slidably provided inside the guide rail 2 and engages with the rack block 4. The back end of the rack 3 and the front end of the guide rail 2 are both provided with hooks 18. The spring 17 is hung inside the two sets of hooks 18.

[0025] The adjustment drive assembly includes a motor 7, a fixing bolt 8, a sleeve 9, an internal thread fixing groove 10 and a gear 13. There are two groups of internal thread fixing grooves 10. The two groups of internal thread fixing grooves 10 are located at the top of one group of support plates 16 away from the other group of support plates 16. The sleeve 9 is sleeved on the top of the outer side of one group of support plates 16. A fixing bolt 8 is threaded through the middle position of the sleeve 9 away from the other group of support plates 16, and the fixing bolt 8 extends to the inside of the internal thread fixing groove 10 and cooperates with it. A motor 7 is provided on the side of the sleeve 9 away from the fixing bolt 8, and a gear 13 meshing with gear 2 14 is provided at the output end of the motor 7.

[0026] An upward and a downward limiting rod are respectively provided on both sides of the rotating rod 15, and the inner top and the inner bottom of the two sets of limiting rods are hinged with the pedal sleeve 6.

[0027] A protective sleeve is provided at the middle position of the outer side of the handle 11, and the protective sleeve is made of rubber material.

[0028] Limiting sliders and limiting sliding grooves are respectively provided on both sides of the guide rail 2 and both sides of the rack 3, and the limiting sliders and limiting sliding grooves match each other.

[0029] Working principle: When using, the device can be carried to the designated location and connected to the power supply. Then the patient can sit on the top of the seat cushion 12 and hold the handle 11 with both hands to achieve the stability of the body sitting. Then the patient can step on the inner side of the two sets of pedal plates 6 with both feet respectively. At the same time, the motor 7 can realize the rotation of gear 13. The engagement of gear 13 and gear 2 14 can drive the rotating rod 15 and the rotating disk 5 to rotate at the same time, thereby realizing the rotation of the two sets of pedal plates 6 to simulate the pedaling state of bicycle riding. The motor 7 drives the operation, and the operator does not need to exert leg force to realize the pedaling drive work. This rehabilitation exercise mode is convenient for patients with more serious illnesses to carry out rehabilitation training, so as to start the external force driven exercise mode operation;

[0030] Later, by rotating the fixing bolt 8 to disengage it from the inside of a group of internal thread fixing grooves 10, the fixing of the sleeve plate 9 and the above components can be released, and then the sleeve plate 9, motor 7 and gear 1 13 can be driven to move upward on the outside of a group of support plates 16, so that gear 2 14 is disengaged from the meshing with gear 2 14, and then the fixing bolt 8 is rotated in the opposite direction to fix the upward movement of the sleeve plate 9 and the above components. Finally, the patient can use the leg force to pedal the foot pedal sleeve 6 to rotate the rotating rod 15 and the rotating disk 5 at the same time. Through this rehabilitation mode, rehabilitation exercises can be carried out for patients whose legs can exert force independently, so as to facilitate the use of functions for different types of patients and improve the flexibility and practicality of the device.

[0031] At the same time, the rack 3 is pushed to move inside the guide rail 2 so that the rack 3 can be engaged with the tooth block 4. Finally, the motor 7 is placed at one end of the back side of the guide rail 2 to perform a hook limit operation with the hook 18, so as to facilitate the limit adjustment of the movement of the rack 3. Through the installation adjustment of the spring 17 and the spring resistance of the spring 17 itself, when the patient rotates the rotating disk 5 by pedaling, the rack 3 can be moved during the rotation of the rotating disk 5 through the cooperation of the tooth block 4 and the rack 3, and then the rack 3 can stretch the spring 17. At this time, the spring 17 can increase the rotation resistance of the rotating disk 5 in the later stage, further enhance the patient's rehabilitation exercise effect, and thus improve the quality of the later exercise of the device.

[0032] At the same time, through the incomplete design of the tooth block 4 and the meshing with the rack 3, when the tooth block 4 is disengaged from the meshing with the rack 3 in the later stage, the rack 3 can be restored by the spring 17, and then the intermittent resistance rotation exercise operation can be easily realized in the later stage.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
