A device based on magnetorheological fluid for suppressing tremor of finger joints

Abstract

The invention discloses a finger joint tremor suppression device based on magnetorheological fluid, which comprises a signal collection unit, a signal processing device, a soft glove, a sealing port, a magnetic field generating device, a magnetorheological fluid, an outer layer of a soft glove, and an inner layer of a soft glove Floor. The beneficial effects of the present invention are: by measuring the tremor signals of each knuckle and phalanx of the hand, respectively controlling the magnetic field generating devices at the corresponding knuckles, and then generating different magnetic field strengths to realize the precise anti-tremor control of each knuckle, targeted Realize anti-shock of patient's fingers; use magnetorheological fluid control to replace traditional mechanical equipment control, simplify the overall structure and reduce energy consumption; use magnetically isolated skin-friendly soft materials to avoid magnetic field distribution between magnetorheological fluid areas In addition, the magnetic field intensity at the finger and phalanx is effectively improved, and the wearing comfort of the patient is also improved.

Description

technical field [0001] The invention relates to a finger joint tremor restraining device, in particular to a finger joint tremor restraining device based on magnetorheological fluid, and belongs to the technical field of medical aids. Background technique [0002] People usually refer to the shaking and tremor of the human body, especially referring to a certain part of the body, such as fingers, arms, head, etc., which is called "tremor" in medicine. Tremor is an involuntary, regular, near-sine reciprocating limb movement and is one of the most common neurological symptoms. According to the survey, about 10% of the general population have different degrees of tremor, and about 40% of the elderly have different degrees of tremor. Tremor brings a lot of inconvenience to the daily life of patients with tremor, such as the inability to write and grasp normally. It has a great impact on the patient's life and social life, and even loses confidence in life in severe cases. [...

AI Technical Summary

Problems solved by technology

[0004] However, most anti-tremor devices focus on the anti-tremor problem of the arm and wrist, ignoring the tremor of the fingers themselves

In addition, most anti-vibration devices have the problems of complex mechanism, large space occupation, and poor wearing comfort due to structural rigid connection.
