Description

Technical Field

[0001] The invention relates to a limb rehabilitation exercise device, in particular to a limb rehabilitation exercise device for patients with severe neurological hemiplegia. Background Art

[0002] Neurosurgery is a branch of surgery. It studies the human nervous system, such as the brain, spinal cord and peripheral nervous system, and their related subsidiary organs, using unique neurosurgery research methods on the basis of surgery as the main treatment method. Hemiplegia, also known as hemiplegia, refers to the movement disorder of the upper and lower limbs, facial muscles and lower part of the tongue muscle on the same side. It is a common symptom of acute cerebrovascular disease. The factors causing hemiplegia in neurosurgery include cerebrovascular disease and tumor compression. After surgery, patients are often unable to actively move autonomously or have poor autonomous movement ability due to factors such as mental weakness, hemiplegia, and various drainage tubes. In severe cases, they are often bedridden and lose their ability to live. During the treatment and rehabilitation process of hemiplegic patients, patients need to insist on self-limb rehabilitation exercises to maintain the recovery of body functions.

[0003] Existing rehabilitation devices for hemiplegic patients generally have simple structures and single exercise methods, which are not conducive to patients' rehabilitation exercises for hemiplegic limbs. For example, some patients cannot exert force with their hands at the beginning of exercise, but can exert force after exercising for a period of time. However, the exercise methods of patients who cannot exert force with their hands and those who can exert force are different. Patients cannot adjust and use them according to their exercise needs. The lack of applicability is not conducive to patients' exercise rehabilitation. Summary of the invention

The first drive motor works to rotate back and forth, and the rotation of the first drive motor drives the drive gear to rotate. The rotation of the drive gear drives the arc-shaped gear block meshed with it to rotate. The rotation of the arc-shaped gear block drives the pedal to move. The movement of the pedal drives the lower limbs of the exerciser to flex and extend, which can assist the exerciser in exercising and is beneficial to the patient's rehabilitation. The L-shaped frame is rotated to the front end of the exercise seat through the first damping bearing, and the position of the first box is adjusted through the second damping bearing. When exercising the upper limbs, the pull ring is held and pulled downward, and the pull ring pulls the U-shaped frame. The U-shaped frame pushes the vertical rod and the balloon to move in the filling liquid. After the pull ring is released, it is reset under the welfare action of the balloon. When it is necessary to adjust downward When the force for pulling exercise is applied, the balloon is inflated by an air pump to make the balloon swell larger and increase the buoyancy of the balloon, so as to adjust the force for pulling downward during exercise. When adjusting the force to be smaller, it is only necessary to deflate the balloon. The L-shaped frame is rotated to the front end of the exercise seat through the first damping bearing, and the position of the second box is adjusted through the second damping bearing. When the user who cannot use the upper limbs is exercising, the upper limbs to be exercised are placed on the lifting plate. After the placement is completed, the second drive motor works, and the second drive motor drives the screw rod to rotate. The rotation of the screw rod cooperates with the wire hole opened on the lifting block, so that the lifting block moves up and down on the screw rod. The movement of the lifting block drives the connecting block and the lifting plate installed thereon to move up and down. The lifting and lowering movement of the lifting plate drives the upper limbs to be exercised to swing to a certain extent, so that the upper limbs can be exercised.

[0015] The present invention has a novel structure and an ingenious conception, and is convenient for exercising and rehabilitating the lower and upper limbs of patients with severe neurological hemiplegia. At the same time, it can be used for exercising and rehabilitating users whose upper limbs can exert force autonomously or users who cannot exert force autonomously, and has strong applicability.
