Handling of Over-Infusion or
Under-Infusion The method of delivery isolates the insulin chamber from the patient and the software performs frequent
monitoring of Pump status. Multiple software monitors provide redundant protection against unsafe conditions.
Over-infusion is mitigated by continuous self-tests, layering of redundancies and confirmations, and numerous
other safeguard alarms. Users are required to review and confirm the details of all bolus deliveries, basal rates,
and temp rates to ensure certainty before initiating a delivery. In addition, once bolus deliveries are confirmed,
the user is given 5 seconds to cancel the delivery before it is started. An optional Auto-Off alarm triggers when
the user has not interacted with the pump’s user interface for a pre-defined period of time.
Under-infusion is mitigated by occlusion detection and blood glucose monitoring as blood glucose entries are
recorded. Users are prompted to treat high blood glucose conditions with a correction bolus.
