Exoskeleton-type upper limb rehabilitant robot

Abstract

The invention discloses an exoskeleton-type upper limb rehabilitant robot which relates to the field of medical devices and is used for assisting a cerebral apoplexy patient in completing two movements of bending and stretching of an elbow, inward rotating and outward rotating of a front arm and simulating exercise therapy for performing rehabilitation training. The exoskeleton-type upper limb rehabilitant robot is structurally characterized by mainly comprising a servo motor, a speed reducer, a shaft coupling, a pair of straight gears, a pair of conical gears, an electromagnetic clutch, a shaft, a sleeve, an upper arm support plate, an adjusting bolt, front arm support plates, coupling pins, limiting pins and a limiting baffle, wherein the shaft coupling is connected with the speed reducer and a first transmission shaft; the electromagnetic clutch is connected with a third transmission shaft and a fourth transmission shaft; the sleeve is connected with the first transmission shaft and a second transmission shaft through the coupling pins; a second cylindrical gear is connected with a gear support plate to form hinge connection; a first front arm support plate is connected with a second front arm support plate by the adjusting bolt; the second front arm support plate is fixedly connected with the third transmission shaft. The device is compact in structure, safe, low in cost, and can be worn and can be used in hospitals and families.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an upper limb rehabilitation training robot, which is especially suitable for the upper limb rehabilitation training of stroke patients. Background technique [0002] According to the estimates of the National Cerebrovascular Disease Prevention and Control Office, among the surviving stroke patients, about 75% are incapable of working in varying degrees, and 40% are severely disabled, which has caused a heavy burden to the family and society. Clinical medicine has proved that the earlier the training starts, the greater the plasticity of the brain and the greater the potential of motor function recovery. The upper limbs of the human body are engaged in various complex and delicate activities, and its motor function directly affects the daily life ability of human beings. In clinical rehabilitation, physicians usually conduct one-on-one continuous passive training of the affected l...
