Upper limb rehabilitation trainer with energy accumulators

Abstract

The invention provides an upper limb rehabilitation trainer with energy accumulators. The upper limb rehabilitation trainer comprises a left upper limb mechanism and a right upper limb mechanism, theleft upper limb mechanism and the right upper limb mechanism are bilaterally and symmetrically mounted on the left side and the right side of a guide rail, a right vertical rotating shaft is rotatablyconnected with a right connecting frame of the right upper limb mechanism, a piston rod of a first right hydraulic cylinder is connected with a first right gear fixed onto the right vertical rotatingshaft through a first right rack engaged with the first right gear, the first right hydraulic cylinder is fixed on a connecting frame, a right swinging support is fixed at the upper end of the rightvertical rotating shaft, a right horizontal rotating shaft is rotatably connected on the right swinging support, a second right gear fixed on the right horizontal rotating shaft is engaged with a second right rack, one end of the right rack is connected with a right cylinder and a piston rod of a second right hydraulic cylinder, the right cylinder and the second right hydraulic cylinder are fixedon the right swinging support, the right cylinder is connected with a right energy accumulator through a three-position four-way valve, and the first right hydraulic cylinder and the second right hydraulic cylinder are connected with a first left hydraulic cylinder and a second left hydraulic cylinder through the three-position four-way valves.

Description

technical field [0001] The invention relates to an upper limb rehabilitation training device with an energy accumulator, which belongs to the field of rehabilitation medical equipment. Background technique [0002] With the continuous development of rehabilitation, the functions of rehabilitation training devices tend to be diversified. At present, one side of the upper limb of the patient can move independently to drive the other side of the upper limb rehabilitation training device. Most of the rehabilitation training devices cannot adjust the distance of the rehabilitation training device. The shoulder width of each patient Different, the rehabilitation trainer needs to be designed with multiple specifications. At the same time, due to the influence of the weight of the rehabilitation training mechanism during the lifting and lowering of the patient's upper limbs, the strength and speed change significantly. In addition, how the patient loads the adjustable damping during ...

[0002] With the continuous development of rehabilitation, the functions of rehabilitation training devices tend to be diversified. At present, one side of the upper limb of the patient can move independently to drive the other side of the upper limb rehabilitation training device. Most of the rehabilitation training devices cannot adjust the distance of the rehabilitation training device. The shoulder width of each patient Different, the rehabilitation trainer needs to be designed with multiple specifications. At the same time, due to the influence of the weight of the rehabilitation training mechanism during the lifting and lowering of the patient's upper limbs, the strength and speed change significantly. In addition, how the patient loads the adjustable damping during the rehabilitation training process is a lot of rehabilitation. What the trainer cannot achieve
