Background technique

Neurology is an independent secondary discipline that does not belong to the concept of internal medicine. The nervous system consists of the brain, spinal cord and peripheral nerves. Neurology is a clinical medicine that studies nervous system diseases and skeletal muscle diseases, mainly through internal medicine. The types of diseases include spinal cord, cerebrovascular diseases, central nervous system infections, demyelinating diseases, movement disorders, epilepsy, headaches, degenerative diseases, and genetic diseases of the nervous system. Cerebrovascular disease refers to a group of diseases with cerebral hemorrhage or ischemic injury symptoms as the main clinical manifestation caused by cerebral blood vessel rupture or thrombosis.

After treatment, patients with cerebrovascular disease will often leave sequelae. The recovery process of cerebrovascular disease is long, such as muscle atrophy and inconvenience in the legs.

By placing the patient's heel on the support seat 233, the sole surface of the foot is attached to the fixed slider 231, and the patient's sole is fixed with the fixing belt 234 to avoid the sole of the foot from shaking; In order to adapt to the inclination of the legs when the height of the support base 233 is raised.

In this embodiment, in order to make the knees of the patient's feet be pushed up first, so that the legs can be bent later, the number of teeth of the first sprocket 331 is greater than the number of teeth of the second sprocket 332, so that the rotation speed of the crank screw 214 is faster than that of the moving leg. The rotation speed of the screw causes the knee to be pushed up first, and then the moving vertical plate 221 starts to slide. In the initial position, the horizontal distance between the curved leg slider 215 and the driving motor 31 is greater than the horizontal distance between the moving slider 222 and the driving motor 31, so that the curved leg sliding block 215 can move to the curved leg polished rod 216 in a short time, thereby limiting the The curved leg hinge seat 213 continues to rise.

When the main shaft 32 rotates, the crank screw 214 drives the crank slider 215 to move, and then squeezes the first crank rod 211, so that the crank hinge seat 213 is pressed against the inner side of the knee, and the knee is lifted, so that the leg is lifted. Bend slightly; at the same time, move the vertical plate 221 to move, push the feet, and the legs continue to bend; when the curved leg slider 215 moves to the connection between the curved leg polished rod 216 and the curved leg screw 214, the curved leg slider 215 stops moving, and The curved leg hinge seat 213 stays at the height at this time, and the moving riser 221 continues to push the patient's leg to bend.

When the patient's legs are stretched, the moving vertical plate 221 moves toward the foot end of the bottom plate 10. When the inner side of the knee is pressed against the hinged seat 213 of the curved leg, the first curved leg rod 211 presses the curved leg slider 215 to the curved leg screw rod. 214 slide up, at this time, the curved leg screw 214 rotates in the opposite direction, so that the curved leg screw 214 drives the slider to move to the foot end of the bottom plate 10, and the curved leg hinge seat 213 moves downward; Repetitive exercise for legs and leg extensions.

As shown in FIG. 2 , in this embodiment, a binding band 40 is provided on the bottom plate 10 , a binding ring 41 is provided on the side of the bottom plate 10 , one end of the binding band 40 is fixed on one side of the bottom plate 10 , and the other end is connected from the bottom plate The top of 10 goes around, and then passes through the binding ring 41 and then sticks back to the top surface of the binding tape through Velcro. When the patient's legs are bent, the patient's waist is fixed with a binding belt to prevent the waist from being separated from the bottom plate 10, and also to prevent the patient's waist from moving.

In this embodiment, there are two leg movement mechanisms 20 and two driving mechanisms 30 , and the two leg movement mechanisms 20 are arranged on the bottom plate 10 side by side, respectively driving the patient's legs to do bending and stretching movements.

The working principle of the present invention: when using, first place the patient's leg at the position of the first chute 11, bind the foot to the fixed slider 231, and use the binding strap 40 to fix the patient's waist; then start The forward rotation of the driving motor 31 makes the main shaft 32 rotate, and the first transmission group 33 drives the crank-leg screw 214 to rotate, so that the crank-leg screw 214 drives the crank-leg slider 215 to move toward the waist end of the bottom plate 10 , thereby making the crank-leg slider 215 Push the first curved leg rod 211, so that the curved leg hinge seat 213 is lifted against the inside of the knee, so that the patient's leg is bent; when the knee is lifted inward, the main shaft 32 drives the moving solenoid 224 to rotate, so that the moving screw The tube 224 drives the moving slider 222 to slide toward the waist end of the bottom plate 10, so that the moving vertical plate 221 pushes the patient's feet to bend the legs; while the moving solenoid 224 rotates, the moving solenoid 224 drives the first gear 341 to rotate , so that the transmission shaft 343 drives the storage wheel 344 to rotate, so that the transmission cable 345 is continuously rolled on the storage wheel 344, so that the transmission cable 345 pulls the fixed slider 231 to move upward on the moving vertical plate 221, so that the legs are bent When the legs move, the height of the feet rises, so that the legs are bent and pressed toward the waist;

When the patient's leg is bent, the driving motor 31 is reversed, and the moving vertical plate 221 moves the foot to the foot end of the bottom plate 10, so that the leg begins to stretch; The slider 215 moves to the curved leg screw 214, so that the curved leg slider 215 moves to the foot end of the bottom plate 10, and the height of the curved leg hinge seat 213 decreases. When the moving vertical plate 221 slides back, the fixed slider 231 moves downward. Move until the legs are extended; repeat the above leg bending and extension to work the leg muscles.
