Active and passive rehabilitation training aid for upper and lower limbs

Abstract

The invention discloses an active and passive rehabilitation training aid for upper and lower limbs. The training aid comprises an upper limb training part, a lower limb training part, a horizontal cross beam, a lifting stand column for adjusting the relative height of the upper limb training part and the lower limb training part and a base, wherein the horizontal cross beam is arranged at the upper end of the lifting stand column, and the lower end of the lifting stand column is fixed on the base; the upper limb training part is arranged on the horizontal cross beam and the lower limb training part is fixed on the base; the upper limb training part can rotate horizontally by 180 degrees around the vertical axis; the upper limb training part comprises a crank, a crank switching block, a knob and a speed reducer; an output shaft of the speed reducer is coaxially connected with the crank and the crank switching block, the crank switching block and the output shaft of the speed reducer are circumferentially fixed in a key fit manner, and a rolling bearing is mounted between the crank switching block and the crank; and the knob is fixedly connected with the crank and can be screwed inor out of the crank switching block. Linkage and separation of the crank and the output shaft of the speed reducer through two-section separation type arm crank.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to an active and passive rehabilitation training device for upper and lower limbs. Background technique [0002] For patients whose mobility is recovering, since they cannot get effective rehabilitation training, the upper and lower limb rehabilitation trainer can effectively exercise the upper and lower limb muscles of the patient through treadmill exercise to avoid muscle atrophy. [0003] Existing rehabilitation training devices for upper and lower limbs can realize the coordinated movement of the left and right arms of the upper limbs, but cannot realize single-arm rehabilitation exercises on the left and right sides; when the existing rehabilitation training devices perform horizontal disc-shaped rehabilitation exercises for the upper limbs, the driven side below the training part will still The rotation is easy to cause injury to the patien...

Problems solved by technology

[0003] Existing rehabilitation training devices for upper and lower limbs can realize the coordinated movement of the left and right arms of the upper limbs, but cannot realize single-arm rehabilitation exercises on the left and right sides; when the existing rehabilitation training devices perform horizontal disc-shaped rehabilitation exercises for the upper limbs, the driven side below the training part will still Rotation is easy to cause injury to the patient; the positioning of the existing upper and lower limb rehabilitation devices at the rotation position of the horizontal beam is fixed by knobs, and the positioning in the vertical direction is insufficient, which is prone to danger and is not conducive to transportation
