Fall prevention device

Abstract

The invention discloses a fall prevention device which comprises a sole plate, a pressure sensor, a bolt, a signal transmission line, a first gear, a motor, a second gear, a cable, a data processing device, an acceleration sensor and a myoelectricity sensor. The pressure sensor is installed at one end of the bolt and connected with the data processing device through the signal transmission line; the first gear is connected with the other end of the bolt; the motor is connected with the data processing device through the cable; the second gear is in transmission connection with the motor and the first gear; the data processing device is used for processing signals, real-time status of human body poses is obtained, the motor is controlled according to the human body poses, and height of the bolt is adjusted. The fall prevention device can comprehensively and accurately reflect whether a human body is about to fall, the signals are classified by adopting artificial intelligence technology, current human body pose status is obtained, and the motor is controlled further to adjust the height of the sole bolt so as to prevent patients from falling.

Description

technical field [0001] The invention relates to the field of medical rehabilitation, in particular to a device for preventing falls. Background technique [0002] The instability of plantar pressure often causes damage to the patient's joints, and even causes the patient to fall and be injured. With the development of science and technology, there have been rehabilitation shoes in the field of medical rehabilitation that can quickly adjust the sole posture to prevent patients from falling. [0003] The anti-fall rehabilitation shoes in the prior art mainly adjust the position and posture of the sole according to the change of the human body's foot pressure and the center of gravity, thereby preventing the patient from falling. The control mode of this kind of rehabilitation shoes is relatively simple, and artificial intelligence is rarely used to control the change of the sole position and posture, so it is not direct and sufficient enough to reflect the tendency of the hum...

AI Technical Summary

Problems solved by technology

The control mode of this kind of rehabilitation shoes is relatively simple, and artificial intelligence is rarely used to control the change of the sole position and posture, so it is not direct and sufficient enough to reflect the tendency of the human body to fall, and sometimes only by the patient's foot pressure and the change of the center of gravity It will cause misjudgment, such as judging that the patient's squatting action is about to fall, thus affecting the efficacy of the device
