摘要：
An infusion pump comprises a housing including a compartment structured to receive a syringe, the syringe including a syringe barrel and a syringe plunger moveable within the syringe barrel； a drive mechanism supported by the housing, the drive mechanism structured and arranged to contact the syringe plunger and move the syringe plunger within the syringe barrel； and a syringe plunger position sensor including: a magnet positioned on the drive mechanism； a magnetic sensor array supported by the housing and positioned adjacent to the magnet, the magnetic sensor array configured to generate an output indicative of a magnetic field associated with the magnet； and software installed on the pump and configured to use the output to determine a linear position of the syringe plunger within the syringe barrel.
