Assistive rehabilitation training robot for stroke hemiplegic patients

Abstract

The invention provides an assistive rehabilitation training robot for stroke hemiplegic patients. The assistive rehabilitation training robot comprises an upper-layer armrest frame, a middle-layer detection frame, a lower-layer support frame and a movable base plate which are parallelly arranged in the vertical direction. Each adjacent two of the upper-layer armrest frame, the middle-layer detection frame and the lower-layer support frame are fixedly connected with each other by three telescopic rods and an electric push rod, and the lower-layer support frame is fixedly connected with the movable base plate by lower-layer support rods; an emergency stop switch, a display screen and a control panel are respectively mounted on the outer surface of a U-shaped frame of the upper-layer armrest frame, four tension sensors are peripherally uniformly distributed at the upper edge of the middle-layer detection frame, and a detachable chair is mounted on the lower-layer support frame; two driving wheels and two driven wheels are peripherally symmetrically mounted at the upper edge of the movable base plate, a control box is mounted on the outer surface of a U-shaped frame of the movable base plate, and pedals are further arranged on the U-shaped frame of the movable base plate; the control box is respectively connected with the four tension sensors, motors, the emergency stop switch, the display screen and the control panel. The assistive rehabilitation training robot has the advantage that rehabilitation training requirements of the stroke hemiplegic patients can be met.

Description

technical field [0001] The invention relates to a rehabilitation training robot, in particular to an auxiliary rehabilitation training robot for stroke hemiplegia patients, belonging to the technical field of rehabilitation robots. Background technique [0002] Rehabilitation robot is an important branch of medical robot. Its research runs through many fields such as rehabilitation medicine, biomechanics, mechanics, mechanics, electronics, materials science, computer science and robotics. It has become an international robotics field. Research hotspots. At present, rehabilitation robots have been widely used in rehabilitation nursing, artificial limbs and rehabilitation treatment, which not only promotes the development of rehabilitation medicine, but also drives the development of new technologies and new theories in related fields. At present, research on rehabilitation robots is mainly focused on rehabilitation manipulators, hospital robot systems, intelligent wheelchair...

AI Technical Summary

Problems solved by technology

[0006] The force of upper limbs detected by existing rehabilitation robots cannot reflect the patient's movement state well. Due to the inherent morbid movement characteristics of hemiplegic patients, center of gravity deviation, weakness of lower limbs, excessive reliance on upper limbs to support body weight, etc., relative detection of patients The force of the upper limbs, and the detection of the force of the waist can more accurately reflect the movement state of the patient

[0007] High cost and no promotion: Most of the existing rehabilitation robots use six-dimensional force sensors to detect the force of the patient when walking, and the six-dimensional force sensors are quite expensive
