INFUSION PUMP

摘要

An infusion pump includes a housing having a compartment structured to receive a syringe and a drive mechanism supported by the housing. The drive mechanism is structured and arranged to contact a syringe plunger of the syringe and move the syringe plunger within a syringe barrel of the syringe. The infusion pump further includes a syringe plunger position sensor and a syringe barrel size sensor. The sensors each include a magnet positioned on the drive mechanism and a magnetic sensor array supported by the housing.

1. An infusion pump comprising:
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, andsoftware installed on the pump and configured to use the output to determine a linear position of the syringe plunger within the syringe barrel.
