3.2.3 Checking the iInfusion rate (every 6 months)
Check the infusion flow once every 6 months by the graduate and timer.
Checking method: Use the preset brand IV set with a 60 mL /h rate, fill the infusion
bag with distilled water and access the graduate. Start, run 10 minutes at a 60mL /h rate
and observe the liquid volume in the graduate where 9.5-10.5mL is qualified.
3.2.4 Alarm (every 6 months)
1) Air bubble in tubing
Checking method: Simulate the infusion process and create a bubble by tilting the
drip chamber during the infusion. There should be a visible alarm [Air Bubble] on the
screen, red alarm light flashing, and audible alarm cycling every 15 seconds like
beep-beep-beep …beep-beep…beep-beep-beep …beep-beep….
2) Occlusion
Checking method: Use the preset brand IV set with a 25 mL /h rate, set the occlusion
检 level to be P2, and then close the roller clamp of the IV set. Start the infusion. Within 1
minute, there should be a visible alarm [Occlusion] on the screen, red alarm light flashing,
and audible alarm cycling every 15 seconds like
beep-beep-beep …beep-beep…beep-beep-beep …beep-beep….
3.2.5 Electric and mechanical safety (every 12 months)
To ensure safety, test the insulation voltage, leakage current and earthing resistance
according to the IEC 60601-1.
3.2.6 Checking the internal battery (every 6 months)
Perform the following inspections on the battery every 6 months:
Connect to the AC power supply to recharge the battery for over 10 hours.
Turn on the power.
Set the infusion rate to 25 mL/h and start the infusion. Record the start time.
Operate the system until it stops infusing due to low battery alarm. Record the finish
time.
（1）If the time from the start of the infusing to end of operation is 4 hours or more, the
battery condition is good.
（2）If the time from the start of the infusing to end of operation is 1 to 1.5 hours, the
battery condition is reaching its service life.
（3）If the time from the start of the infusing to end of operation is less than 1 hour, the
battery has reached its service life. Replace the battery. You are advised to contact
the distributor to replace the battery.
When the battery lever check is complete, recharge the battery for next use.
