OCCLUSION RECOGNITION IN AN ADMINISTERING APPARATUS

摘要

A device and a method for controlling a medical administering apparatus are disclosed. An electrical motor of the medical administering apparatus is activated during defined discharging events. The motor is controlled as per a predefined speed profile with a plurality of regions (Pi). A load sensor establishes load signals (Imot) that constitute a measure of the electrical load formed by the motor, e.g. load signals that represent the motor current. A monitoring arrangement compares a variable derived from the load signals with at least one predefined condition and emits an occlusion signal if the condition is satisfied. In order to compensate for acceleration effects, the load signals are corrected as a function of the current region by an associated correction value (I1; I2; I3). This allows reliable recognition of occlusions even in the case of short discharging events.
