Hydraulic rehabilitation training machine for bilateral upper limb associated movement

Abstract

The invention provides a hydraulic rehabilitation training machine for bilateral upper limb associated movement. The rehabilitation training machine comprises a lifting vertical column, a left upper limb mechanism and a right upper limb mechanism; the lifting vertical column fixes a liner guiding rail through a supporting frame, the left upper limb mechanism and the right upper limb mechanism, symmetric about the symmetric surfaces in the left and right directions of a base, are installed on the left and right sides of the linear guiding rail, a right sliding block in the right upper limb mechanism is installed on the linear guiding rail, the right sliding block fixes a right oscillation cylinder supporting frame through a right connecting board, a first right oscillation cylinder and a second right oscillation cylinder are fixed onto the right oscillation cylinder supporting frame, the two ends of a right rotating shaft are fixed by the output shafts of the first right oscillation cylinder and the second right oscillation cylinder, the right rotating shaft fixes a right upper limb oscillation rod, the first right oscillation cylinder is connected with the second right oscillationcylinder in parallel, a first left oscillation cylinder is connected with a second left oscillation cylinder in parallel, two parallel oil lines are connected through a three-position four-way valve,the oil line before the joint of the second right oscillation cylinder and the first right oscillation cylinder which are in parallel connection is provided with a right two-position four-way valve, and the oil line before the joint of the first left oscillation cylinder and the second left oscillation cylinder which is in parallel connection is provided with a left two-position four-way valve.

Description

technical field [0001] The invention relates to a hydraulic bilateral upper limb combined exercise rehabilitation trainer, which belongs to the field of rehabilitation medical equipment. Background technique [0002] The aging population in our country is increasing day by day, and the number of patients with geriatric diseases is also increasing. Upper limb training institutions usually cannot be adjusted in the left and right directions, which reduces the comfort of the patient during the rehabilitation process and affects the rehabilitation effect. speed, and the current rehabilitation training institutions cannot fully meet the needs of the above-mentioned patients in the rehabilitation training process. [0003] The rehabilitation trainer adopts an electric lifting column to meet the needs of different patients' upper limb heights and improve the comfort of patients' rehabilitation exercises. The guide rail slider and lead screw nut mechanism are adopted, and the reve...
