· Mouse: any specified trackball or USB mouse may be used for navigation and data entry.

· Computer keyboard: an USB computer keyboard can be used for data entry instead of the on-screen pop-up keyboard.

[Remark: user has to restart the machine after plug and unplug the mouse / computer keyboard.]

 

· Knob (Standard)

Service Features

· The Support Tool helps technical personnel to

–  carry out configuration, upgrades and troubleshooting on an individual monitor.

– back up the monitor settings.

 

· The Service Mode is password-protected and ensures that only trained staff can access service tests and tasks. It includes Printer Setting, Skin Type, AFM Setting, Brightness Setting, Clear Data, NIBP Calibration, and Touch Screen Calibration.

· The Support Tool uses the USB interface of the fetal monitor for software upgrading.

· The monitor is compatible with Acoustic Fetal Stimulator, which use low frequency vibro-acoustic stimuli (VAS) to “wake” the fetus, increasing the efficiency of antepartum testing and improving retest consistency.

  

· The fetal monitors can be equipped with NST (Non Stress Test) Report function (option) based on Fischer evaluation method to give a score of fetal wellbeing after 20 minutes continuous monitoring, thus helping the doctors make judgment about fetal health condition.

 

· Base line, LTV Amplitude, Period, Acceleration, and Deceleration are 5 indexes of analyzing FHR wave, the software allows interpretation of fetal heart Rate and TOCO traces, and generates a printed report automatically for a reassuring NST
