Flexible finger rehabilitation wrist developer based on Hall pressure induction

Abstract

The invention belongs to the related technical field of finger rehabilitation, and discloses a flexible finger rehabilitation wrist developer based on Hall pressure induction, which comprises a plurality of guide mechanisms, a shell, a plurality of flexible Hall pressure sensors and acquisition modules respectively arranged in the shell, a microprocessor, flexible Hall pressure sensors and acquisition modules. The guide mechanisms are movably connected to the shell and are in contact with the flexible Hall pressure sensors; the acquisition module is connected with the flexible Hall pressure sensor and the microprocessor; the flexible Hall pressure sensor is used for detecting the numerical value of force applied by fingers of a user and transmitting the detected force data to the acquisition module; the acquisition module is used for converting the received force data and transmitting the converted force data to the microprocessor; and the microprocessor is used for controlling the action of the virtual character in the rehabilitation activity according to the received data and storing the received data in real time so as to carry out rehabilitation evaluation on the user. The wrist developer is compact in structure, small in size and high in applicability.

Description

technical field [0001] The invention belongs to the technical field related to finger rehabilitation, and more specifically relates to a flexible finger rehabilitation grip based on Hall pressure sensing. Background technique [0002] The hand is the part with the largest proportion of human activities, and it is also the most vulnerable part. Finger rehabilitation treatment occupies a large proportion in the field of rehabilitation medicine. The weakening and failure of hand function not only prevents patients from participating in social labor, but even loses self-care Ability to create a huge burden on society and families. [0003] Traditional finger rehabilitation mainly uses professional medical staff to perform hand movements on patients, and according to the different conditions of patients, acupuncture and moxibustion and other adjuvant treatments are given. However, the growth rate of professional medical staff is much lower than the demand; on the other hand, eac...

Problems solved by technology

[0005] Active rehabilitation is mainly used in the later stage of rehabilitation. At this time, the fingers have a certain degree of mobility, but there may be problems such as inability to use force and a small range of motion. Compared with the passive rehabilitation stage, it mainly provides exercise, and the active rehabilitation stage mainly provides " "Sensing" function, to sense the patient's recovery situation while finger training

However, most of the existing devices are too bulky to be suitable for rehabilitation training in daily life, and most of them do not have real deformation feedback. When the fingers act on hard objects, they are more likely to be injured.
