Abstract
Syringe pump apparatus and methods for detecting proper or improper engagement of a syringe pump drive system with a syringe in the syringe pump are disclosed. The apparatus and methods can determine proper or improper engagement between a drive system and the plunger of a syringe in a syringe pump by detecting the force required to move a plunger clip in reverse while restricting flow into the syringe. The apparatus and methods may also be used to determine that a syringe in the syringe pump apparatus is properly connected to a delivery line.
