Description

Technical Field

[0001] The invention belongs to the field of medical auxiliary equipment, and in particular relates to a muscle stretching device for assisting Parkinson's disease in neurology. Background Art

[0002] Parkinson's disease, also often referred to as "Parkinson's paralysis," is a neurodegenerative disease. The main cause of this disease is the degeneration and death of dopaminergic neurons in the substantia nigra, which may be related to multiple factors such as genetics, environmental factors, and aging of the nervous system. The symptoms of Parkinson's disease vary from person to person, and the most significant symptoms are resting tremor, bradykinesia, and muscle rigidity. Patients in the middle and late stages develop postural balance disorders.

[0003] Parkinson's disease cannot be cured, but doctors can help patients relieve symptoms through active medical treatment. Comprehensive treatment is adopted for Parkinson's patients, with drug treatment as the first choice and surgical treatment as a supplement. In addition to drug treatment and surgical treatment, rehabilitation treatment is also required. Appropriate rehabilitation training can be carried out according to the patient's existing movement disorders (such as gait disorders, posture balance disorders, language and / or swallowing disorders, etc.).

[0004] At present, there are various rehabilitation training auxiliary equipment to help Parkinson's patients with motor rehabilitation training. However, most patients with movement disorders cannot exercise by themselves when using rehabilitation training equipment. The use of equipment requires personnel to assist patients in various movements. Most devices only train a single part and are not suitable for patients who need muscle stretching in different parts. In addition, it is difficult for patients with severe gait disorders to use general training devices, and there is a risk of muscle strain. Summary of the invention

[0031] Example 1

[0032] See also Figures 1 to 6 As shown, a muscle stretching device for assisting Parkinson's disease in neurology is proposed, comprising a base 1:

[0033] The base 1 is in the shape of a rectangular parallelepiped, with a hinge seat 2 installed in the front middle part of the upper surface of the base 1, a swing support rod 3 is hinged on the hinge seat 2, an L-shaped limit frame 10 is installed on the rear lower side of the swing support rod 3, a hole is opened on the limit frame 10 and a fixing bolt 11 is installed in the hole, a threaded hole 2301 is opened on the base 1 corresponding to the hole of the limit frame 10, the swing support rod 3 can be fixed to the base 1 by the fixing bolt 11, when the swing support rod 3 needs to be swung forward, the fixing bolt 11 can be screwed out to adjust it. A rotating shaft 4 that passes through the swing support rod 3 is laterally installed at the upper end of the swing support rod 3 through a bearing, and two centrally symmetrical connecting rods 5 are installed at the left and right ends of the rotating shaft 4. A rotating pedal 6 is installed on the other end of the connecting rod 5 through a transverse bearing. A rotating fixing belt 7 is installed at the front end of the rotating pedal 6 to fix the user's forefoot, and a heel pad 601 is installed on the rear end of the rotating pedal 6 to prevent the user's foot from slipping during exercise. A hole is opened in the middle of the swing support rod 3 and an auxiliary motor 8 is installed in the hole. The speed of the auxiliary motor 8 can be freely adjusted. The output end of the auxiliary motor 8 is connected to the rotating shaft 4 through a belt 9. The auxiliary motor 8 assists the rotating pedal 6 to rotate, thereby providing exercise assistance to patients with severe gait disorders.

[0034] The upper surface of the base 1 is symmetrically installed with fixed protruding rails 12 on the left and right sides of the hinged seat 2, and the fixed protruding rails 12 are installed with sliding brackets 13 that cooperate with the fixed protruding rails 12, and the sliding brackets 13 are installed with translation pedals 14. An anti-falling block 15 is installed at the front end of the fixed protruding rail 12. The anti-falling block 15 is circular and has a diameter larger than the fixed protruding rail 12, which can prevent the sliding bracket 13 from falling off when sliding forward; a track circular hole seat 16 is installed at the rear end of the fixed protruding rail 12, and a hole parallel to the fixed protruding rail 12 is opened on the track circular hole seat 16.

[0035] A hand support frame 17 is vertically installed on the left and right sides of the upper surface of the front end of the base 1, and a slide groove 1701 is opened on the outer side of the hand support frame 17. A top circular hole seat 18 is installed on the top of the hand support frame 17, and a hole in the front-back direction is opened on the top circular hole seat 18. A pulling rope 19 is connected to the rear side of the sliding bracket 13. The other end of the pulling rope 19 first passes through the circular hole of the track circular hole seat 16, and then passes through the slide groove 1701 of the hand support frame 17 from bottom to top and passes through the top of the hand support frame 17 and then passes through the hole opened in the top circular hole seat 18. Finally, a pull ring 20 is installed at the end of the pulling rope 19, and the translation pedal 14 on the sliding bracket 13 is connected to the pull ring 20 through the pulling rope 19;

[0036] A top pulley 1703 is installed at the slide groove 1701 above the hand support frame 17 that contacts the pulling rope 19. The axis of the top pulley 1703 is perpendicular to the pulling rope 19, which can assist the pulling rope 19 to slide on the top of the hand support frame 17; a bottom pulley 1702 is installed at the slide groove 1701 below the hand support frame 17 that contacts the pulling rope 19. The axis of the bottom pulley 1702 is perpendicular to the pulling rope 19, which can assist the pulling rope 19 to slide on the bottom of the hand support frame 17.

[0037] A support 21 is installed on the upper surface of the base 1 just behind the hinge seat 2, a telescopic rod 23 is sleeved inside the support 21, a seat 22 is installed on the upper end of the telescopic rod 23, a hole is provided on the support 21 where the telescopic rod 23 is sleeved, and an adjusting bolt 2101 is installed in the hole, and a plurality of threaded holes 2301 with the same inner diameter as the diameter of the adjusting bolt 2101 are provided on the telescopic rod 23. The height of the seat 22 can be adjusted by changing the adjustment bolt 2101 and cooperating with different threaded holes 2301 of the telescopic rod 23.

[0038] When Parkinson's patients use this device for training, they can choose to perform gait training with both feet. First, the seat 22 is adjusted to a height suitable for walking training, and the soles of both feet are inserted into the translation pedal 14 and fixed with the rotating fixing belt 7, and then training can begin. If the patient's gait disorder is serious, the auxiliary motor 8 can be turned on as needed and a suitable speed can be selected to assist the patient in exercise.

[0039] When it is necessary to perform muscle stretching training with both hands and feet at the same time, first unscrew the fixing bolt 11 out of the base 1, then adjust the swing support rod 3 forward, then lower the height of the seat 22 to lower the patient's sitting posture, so that the legs can be flexed and extended, and then fix the soles of the feet on the translation pedal 14 through the translation fixing belt 1401, and then pull the pull ring 20 with both hands. When the patient's legs move forward, the sliding bracket 13 pulls the traction rope 19 forward, and the traction rope 19 at the other end drives the pull ring 20 to move upward until the legs are straightened and the hands are also straightened. When the hands pull the pull ring 20 downward, the traction rope 19 pulls the sliding bracket 13 to drive the translation pedal 14 to move backward, so that the patient's hands and feet are bent at the same time, and the muscle stretching training can be performed continuously in this way. The embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiment does not describe all the details in detail, nor does it limit the invention to only the specific implementation method described. Obviously, many modifications and changes can be made according to the content of this specification.
