MONITORING A DISPENSING PROCESS WITH A DRUG DELIVERY DEVICE

A method for monitoring a dispensing process of a liquid drug with a drug delivery device involves gradually increasing a motor drive current for a motor of the drug delivery device; measuring, by a sensor, a position or movement of an output member movable by the motor; determining a minimal motor...

Zusammenfassung:	A method for monitoring a dispensing process of a liquid drug with a drug delivery device involves gradually increasing a motor drive current for a motor of the drug delivery device; measuring, by a sensor, a position or movement of an output member movable by the motor; determining a minimal motor drive current required to initially move the output member from standstill; and determining, from an evolution of successively determined minimal motor drive current values, a delivery device operation status.
