Infusion pump including syringe sensing
First Claim
1. An infusion pump operable with a syringe having a syringe barrel and a syringe plunger moveable within the syringe barrel, the infusion pump comprising:
- a housing structured to receive the syringe, the housing including a syringe clamp for contacting the syringe barrel;
a drive mechanism supported by the housing, the drive mechanism structured and arranged to contact and end of the syringe plunger so as to be able to move the syringe plunger within the syringe barrel;
a syringe barrel size sensor includinga magnet moveable with the syringe clamp when clamping the syringe barrel, anda sensing member supported by the housing and configured to generate an output indicative of a magnetic field associated with the magnet; and
software installed on the pump and programmed to use the output to determine a size of the syringe barrel received by the compartment.

Abstract
An infusion pump operable with a syringe having a syringe barrel and a syringe plunger includes a housing having a compartment to receive the syringe and defining a wall, and a syringe clamp moveable towards and away from the wall, the syringe clamp contacting the syringe barrel; a drive mechanism supported and structured and arranged to contact and end of the syringe plunger so as to be able to move the syringe plunger within the syringe barrel; a syringe barrel size sensor including a magnet operably coupled to the syringe clamp, and a sensing member supported by the housing and configured to generate an output indicative of a magnetic field associated with the magnet; and software installed on the pump and programmed to use the output to determine a size of the syringe barrel received by the compartment.
