Rehabilitation robot and fall detection and protection method thereof

Abstract

The invention discloses a rehabilitation robot and a fall detection and protection method thereof. The rehabilitation robot includes: a control unit, a motion following unit and a human body support mechanism; the control unit is used to set the initial position height of the human body center of mass, and sends a motion command to the motion following unit; the motion following unit is used to Control the human body support mechanism to move up and down following the up and down movement of the human body center of mass; the control unit is also used to obtain the real-time position height of the human body center of mass in real time, calculate the height difference between the real-time position height and the initial position height, and when the height difference meets the preset conditions Send a braking command to the motion following unit; the motion following unit is also used to control the human body support mechanism to stop moving up and down after receiving the braking command. The present invention can be applied to patient rehabilitation training, especially in the scene of lower limb exercise training, to detect whether the patient has a tendency to fall, while providing effective protection without interfering with the movement of the patient's trunk and upper limbs.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a rehabilitation robot and a fall detection and protection method thereof. Background technique [0002] In 2017, there were about 13 million new stroke patients in my country every year, with a growth rate of about 8%. The loss or impairment of motor function caused by stroke seriously affects the quality of life of patients and brings a great burden to patients' families and society. Evidence-based medicine shows that rehabilitation is the only effective means of reducing disability rates. Among them, the movement function has a great impact on the quality of life and health of patients, and it is the most basic motor function, the recovery of lower limb motor function. Traditional rehabilitation training has shortcomings such as insufficient doctors, single-function equipment and high cost, long rehabilitation cycle, tedious process, poor initiative, and inability t...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to overcome the defects that it is difficult to detect the patient's fall state in the prior art, and the fall protection is not conducive to the patient's trunk swing and upper limb swing during walking exercise, and to provide a device that can accurately detect whether the patient has fallen and Rehabilitation robot providing protection when falling down and fall detection and protection method thereof
