Technical Features
Bolus Delivery Accuracy:
Bolus delivery accuracy data were generated based upon IEC 60601-2-
24:2012. Testing was performed with distilled water at room temperature
with a 9-mm cannula, 60-cm long Neria Guard infusion set.

Delivery Accuracy Under High Backpressure:
Delivery accuracy data were generated under simulated high
back-pressure conditions (such as from partial occlusions) and using the
time to detect as the test window. This effectively characterizes the mean
ow rate error that could occur under these conditions both including the
initial 30-60 min start-up period, and within the steady-state period to
which the system subsequently converges.
