11.3.2 Check the alarm function of occlusion sensor (once every 2 months)
Check if the Occlusion alarm is given within 2-10 seconds.
(1)
The testing conditions: The Infusion Pump should be 20cm away from the flow clip of IV set and
30cm away from the filter, flow rate at 150 ml/h, volume to be infused as 200ml, and occlusion level as
middle.
(2)
Install IV set in the Infusion Pump. Close the door and open the flow clip of IV set.
(3)
Upon pressing START key, use a stopwatch to measure the time taken for occlusion alarm.
11.3.4 Inspect delivery accuracy (once every 2 months)
The Infusion Pump built in mechanism driving system which may suffer abrasion during usage.
Frequently use of the machine and variation on temperature may cause accuracy error. It requires
check infusion accuracy periodically.
(1)
Install IV set in the Infusion Pump. Close the door and open the flow clip of IV set.
(2)
Calibrate the accuracy as per instructions of 8.3.7.
(3)
After calibration, setting flow rate at 150ml/h and volume to be infused as 10ml to test delivery
accuracy. The delivery accuracy should be 3%.
11.3.5 Inspect internal battery
The battery shall reduce the performance due to prolonged usage, please check the battery capacity
every other month.
(1)
First recharge the battery fully 10 hours with power on, or 3 hours with power off).
(2)
Let Infusion Pump work on battery only and set flow rate at 25ml/h. Record the whole working time
when the battery is exhausted.
---If infusion time more than 90 minutes, the battery is in good condition.
---If Infusion time more than 45 minutes but less than 90 minutes, the battery starts low quality but still
can be used.
---If infusion time less than 45 minutes, the battery reaches the end of its life and needs to be replaced.
Replace internal battery
