Infusion Precision

At 1U/h delivery rate, the error was measured at 0,4%.

Occlusion Detection (Maximum Infusion Pressure)

When the pressure inside of the reservoir reaches a maximum of 100kPa±30kPa, the occlusion alarm will occur and the motor system will rewind automatically.

Occlusion Alarm Time

When a fluid obstruction is detected, an occlusion alarm occurs. An average of 2,5U of insulin will be delivered before this alarm appears.

Overdose/Underdose

The pump contains sensors whose sole purpose is to verify the infusion accuracy.

If the actual amount of delivery is more or less than the requested amount, this is called an overdose or underdose. The sensors in the pump can detect overdose or underdose situations and compensate automatically, or issue an alarm.

The maximum amount of bolus that can be delivered in a single fault is 0,25U.
