Wearable intelligent lower limb rehabilitation device and control method

Abstract

The invention discloses a wearable intelligent lower limb rehabilitation device and a control method. One side of a left waist main supporting element and one side of a right waist main supporting element of the device are connected together through a waist adjusting mechanism, a left back support and a right back support are fixed to waist main supports on the corresponding sides respectively, and a main control box is fixed to the back supports through connecting pieces; hip joint driving mechanisms are connected with G-type structures of the waist supporting elements; the device further comprises hip joint execution mechanisms, knee joint execution mechanisms and foot mechanisms; a vital sign monitoring device is located on the right arm of a human body. The control method includes the steps that a sensor measures pressure signals, pulse signals and blood pressure signals, the signals are processed through a central processing unit, servo motor control parameters and patient vital sign parameters are generated and displayed through a display screen, and communication with peripheral large equipment is achieved through WIFI. The device is simple in circuit, easy to operate, safe and reliable, and rehabilitation speed is increased.

Description

technical field [0001] The invention belongs to the field of medical auxiliary treatment research, and in particular relates to a wearable intelligent lower limb rehabilitation device and a control method. Background technique [0002] With the continuous development of society, people's living standards and medical care levels have been greatly improved, so that the average life expectancy of the people has also increased from about 60 years in the 1960s and 1970s to about 75 years old today, approaching the world's developed countries. On average, with the increase of average life expectancy, the proportion of the elderly in the total population of the society is also increasing. As of 2010, the elderly population over 60 years old in my country has exceeded 178 million, reaching 13.26% of the total population. At the same time, the elderly population over the age of 65 is about 119 million, accounting for 8.87% of the total population, and the problem of social aging is be...

Problems solved by technology

The traditional way of rehabilitation training is that doctors train patients with bare hands, which is obviously inconvenient, so many medical institutions have introduced rehabilitation robots

[0004] However, the lower extremity rehabilitation robot exoskeleton currently on the market has many limitations: the exoskeleton drive system mostly uses hydraulic or pneumatic drive, the control accuracy is not high, and the noise is large, and the drive system shell adopts a fixed structure. In order to ensure the rotation angle of the joint, Many internal mechanisms are exposed, and it is easy to cause harm to the user; in addition, the existing exoskeleton can only ensure the normal operation of the mechanism, and cannot detect the physical condition of the patient during use, and the patient cannot intuitively understand the operation of the equipment
