Digital 4 Channel EMG Machine/EP System PC Based Evoked potential

 

Brief introduction

Introduction:

The equipment records bioelectricity activity of nerve muscle for determining its function state, which combines with nerve conduction speed, to give patient an auxiliary diagnosis.

Checking contents: EMG(electromygram), MCS(motor nerve conductor velocity), SCS(sensory nerve conductor velocity), F wave, Hreflex, RNS(repetitive nerve stimulation), Blink Reflex, VEP(visual evoked potential), BAEP(brainstem auditory evoked potential), SEP(somatosensory evoked potential), etc.


Features:


Professional EMG/EP operation platform and perfect test items, complete each test in the shortest time.

Neuro and muscle navigation system, convenient in selecting test part.

Powerful normal values system, contrast with normal data automatically.

Flexible software design, configure system parameters according to requirements.

High-speed data collection, electromagnetic interference suppression, Photoelectric isolation and low noise.

Integrative hardware system, compact in configuration and easy in moving.
