Wearable finger joint angle displacement data synchronous acquisition system

Abstract

The invention discloses a wearable finger joint angle displacement data synchronous acquisition system, belonging to the field of wearable data acquisition equipment. The system comprises a wearing unit, a data acquisition unit and a data processing unit. According to the invention, an angle sensor and a displacement sensor synchronously collect angle data of all joints and displacement data of corresponding fingers in a finger movement process of a patient, convert collected analog signals into digital signals through an A / D converter and then transmit the digital signals to a STM32 single-chip microcomputer; then the STM32 single-chip microcomputer filters the transmitted data and then transmits the data to an upper computer through a wireless transmission module; and the upper computer is used for processing the data and establishing a data model about angle data and displacement data when all joints of the fingers act synergistically. Thus, a rehabilitation assistive device aiming at the condition of the hand of a specific patient can be developed, the targeted assistive device can help the hand of the patient to perform efficient rehabilitation, and secondary injury to the dyskinesia part of the hand of the patient is avoided.

Description

technical field [0001] The invention relates to the field of wearable data acquisition equipment, in particular to a system for synchronous acquisition of finger joint angular displacement data. Background technique [0002] With the development of science and technology and the urgent need in the field of medical rehabilitation, wearable rehabilitation aids have increasingly become a research hotspot. In recent years, there have been more and more cases of hand motor dysfunction caused by factors such as stroke and accidents. Studies have shown that the human hand is dominated by a large number of nerves and can perform many fine activities. Therefore, hand movement disorders have also become a major factor hindering the rehabilitation process of patients. How to use high-precision hand rehabilitation assistance based on multiple data references More and more people pay attention to the efficient rehabilitation work of the patient's hand by the appliance. [0003] Among t...

Problems solved by technology

Therefore, if you simply consider the control of a certain joint of the finger and the overall control of the flexion and extension of the hand, and ignore the angle and displacement of each finger joint under the synergistic effect, it is likely to cause secondary damage to the injured finger joint of the patient. harm
