Active-and-passive rehabilitation training instrument for multiple joints of upper limb

Abstract

Provided is an active-and-passive rehabilitation training instrument for multiple joints of an upper limb. The active-and-passive rehabilitation training instrument comprises a rack, wherein a main machine is connected with the rack, and a rotation driving device is arranged in the main machine; an output shaft is driven by the rotation driving device to rotate, and a rotating arm is connected with the output shaft; the rotating arm is fixedly connected with a positioning piece and an eccentric shaft sleeve, and the eccentric shaft sleeve is sleeved with an inner eccentric sleeve through an eccentric hole; a spring piece is arranged on the bottom of the inner eccentric sleeve radially and outwards, and a clamping piece is arranged on the spring piece and toward the positioning piece; the outer wall of the inner eccentric sleeve is sleeved with an inner ring of a first bearing, and the outer ring of the first bearing is sleeved with an outer sleeve base; a hinge shaft is arranged on the radial outer side of the outer sleeve base, and an arm fixation connecting frame is rotatably connected with the hinge shaft, and both sides of the vertical edge of an L-shaped handle are provided with a first side shaft and a second side shaft; the arm fixation connecting frame is rotatably connected to the first side shaft, and a second bearing is arranged in an eccentric shaft hole; the second side shaft is arranged in an inner ring hole of the second bearing. The training instrument is adjustable in amplitude and good in training effect.

Description

technical field [0001] The invention relates to a multi-joint active and passive upper limb rehabilitation training instrument, which belongs to the technical field of medical equipment. Background technique [0002] Rehabilitation training for patients with upper limb dysfunction caused by cerebrovascular, brain injury, and nervous system diseases can effectively solve the spasm problem of patients with upper limb dysfunction, slow down the atrophy of upper limb muscles or joints, enhance upper limb muscle strength and reduce shoulder and back pain At present, the equipment for upper limb joint training has problems such as single function, unadjustable training range and training intensity, or inconvenient adjustment, especially for wrist training equipment. Patients with upper limb dysfunction need a Rehabilitation training equipment with scientific design and convenient training. Contents of the invention [0003] The object of the present invention is to overcome the...
