Software function

1.System self-checking function

System will check each part of hardware can work normally when it is powered on to ensure patient safe.

 

2.Case database management system

The function in this module include: add, delete, modify query, import and export cases information. In addition, the system also provides advanced and intelligent search function for case

 

3.Projects select

The module is the bridge connection case database and checking project. It provides information with graph and characters, which is convenient for user to select test part and project.

 

4.Impedance test

To achieve optimal test effect, firstly open impedance test function to record that the impedance of body surface complies with condition which is less than SK.

 

  1. Perfect EP/NCS/EMG test system.

The detailed test projects are showed as below:

5.1 EP system: including SEP, VEP (which contains EP-mode switch and flash) and BAEP.

5.2 NCS

5.2.1 MCS

The system can analyses the collection waveform and adjust baseline automatically, and nerve conduction velocity in two nerve segments and latency can be calculated.

5.2.2 H Reflex

H-wave latency ,H-wave amplitude and H/M rate can be calculated.

5.2.3 SCS

Get bigger signal noise ration (SNR) and strong anti-interference capability by lesser superimposed waveform. And nerve conduction velocity in tow nerve segments and latency can be calculated.

5.2.4 F Wave

This Window displays two waveform (M wave in left and F wave in right),It can calculate F-wave latency , F-wave Amplitude, F-Wave occurrence, F/M amplitude rate and F-wave conduction velocity.

5.2.5 RNS

Many Repetitive stimulation checks can be done in one test, and stimulation waveform amplitude, amplitude decremental percentage, waveform area decremental percentage  can be calculated.

5.2.6 Blink Reflex

Dual-channel collection can record trigeminal signal from two sides.

5.3 Standard EMG system

This system reduces baseline drift by superimposing eight EMG waveforms, real time analyse motor unit potential and interference phases.
