Embodiment Construction

[0014] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0015] The surface muscle signal collector of the present invention comprises a central processing unit and a signal conditioning circuit connected with the central processing unit, a voltage detection circuit, a signal conversion circuit and a memory, the signal conditioning circuit is connected with an EMG collecting electrode, and the signal conversion The circuit is also connected with the USB interface.

[0016] According to neurophysiological knowledge, the muscle action potential will generate a potential difference of -90mV to 30mV. Since the human body is a poor conductor of electricity (internal resistance on the order of 1MΩ), only a peak value of about 1mV can be obtained from the patch electrode on the body surface. SEMG is often mixed with very low frequency (clo...

Abstract

The invention discloses a surface electromyogram signal acquiring device, which comprises a central processor as well as a signal conditioning circuit, a voltage detection circuit, a signal conversion circuit and a memory which are connected to the central processor, wherein the signal conditioning circuit is connected to an EMG (electromyogram) acquisition electrode; and the signal conversion circuit is additionally connected to a USB interface. The surface electromyogram signal acquiring device disclosed by the invention can greatly reduce the interface source of an electromyogram signal and improve using convenience thereof, and the acquiring device is convenient and flexible to use and low in interference on the acquired electromyogram signal.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a surface muscle signal collector. Background technique [0002] Electromyography (EMG) is the temporal and spatial superposition of motor unit action potentials (MUAPs) in numerous muscle fibers. Surface electromyography (SEMG) is the combined effect of superficial muscle EMG and electrical activity on the nerve trunk on the skin surface, which can reflect neuromuscular activity to a certain extent; compared with needle electrode EMG, SEMG is non-invasive in measurement , non-invasive, simple operation and other advantages. Therefore, SEMG has important practical value in clinical medicine, ergonomics, rehabilitation medicine and sports science. [0003] With the development of detection technology and signal processing means, using SEMG instead of needle electrode EMG for comprehensive clinical non-destructive diagnosis has become one of the hot issues in biomedicine and me...
