Non-fixed-contact-type myoelectric acquisition system and myoelectric acquisition method thereof

Abstract

The invention discloses a non-fixed-contact-type myoelectric acquisition system and a myoelectric acquisition method of the non-fixed-contact-type myoelectric acquisition system. The system comprises a plurality of myoelectric acquisition units, an electrode-array fixing device and a radio-frequency receiving module, wherein the myoelectric acquisition units are detachably installed on the electrode-array fixing device in the form of an array, and each myoelectric acquisition unit is wirelessly connected with the radio-frequency receiving module; the electrode-array fixing device is used for placing the myoelectric acquisition units, the myoelectric acquisition units and the skin are closely contacted by adjusting the electrode-array fixing device, and a connecting passage of a reference potential is provided for each myoelectric acquisition unit; the radio-frequency receiving module is wirelessly connected with the myoelectric acquisition units and is used for receiving myoelectric-signal characteristic information sent by each myoelectric acquisition unit and transmitting the myoelectric-signal characteristic information to an information processing terminal. According to the non-fixed-contact-type myoelectric acquisition system and the myoelectric acquisition method, a previous complicated cumbersome myoelectric acquisition device is changed and replaced with a wireless myoelectric-signal acquisition device which has the advantages of small size, light weight, low price, flexibility in placement, reusability and greater application value.

Description

technical field [0001] The invention relates to a bioelectric signal collection, processing and transmission instrument in the technical field of electrophysiological diagnosis equipment, in particular to a non-fixed contact myoelectric collection system and a myoelectric collection method based on human physiological characteristics. Background technique [0002] With the continuous advancement of science and technology and the continuous increase of the number of patients in hospitals, portable medical equipment has emerged as the times require, and people can use safe and reliable medical equipment without leaving home. [0003] Myoelectric signal is the electrical signal accompanying muscle contraction, and it is an important method for non-invasive detection of muscle activity on the body surface. Neuromuscular bioelectrical signals are collected from the muscle surface through electrodes, and are recorded, amplified, transmitted, and fed back to perform quantitative as...

AI Technical Summary

Problems solved by technology

[0004] However, the usual EMG signal collection system is cumbersome to use, high in cost, and usually needs to wear an information recording device, and needs to smear a conductive medium on the skin, which is worth the poor patient experience.

Moreover, each electrode needs to be connected to the information recording device through a wire, so that the patient is often covered with wires during the measurement process, which not only affects the movement but also greatly interferes with the signal due to the displacement of the electrode during the movement.
