Abstract: A modular system (10) is disclosed for use, e.g. in infusion systems. The system includes a base unit (20) and one or more modules (30). A mechanical/electrical connecting system (21 to 24) is disclosed enabling safe connection of the various units in the system while enabling easy disconnection of any of the modules (30). A signal processing arrangement is also disclosed enabling the number of modules (30) in the system to be sensed by the base unit (20).

Abstract: A syringe pump is disclosed, having a housing, a motor driven pusher for pushing the plunger of a syringe and various transducers to determine error conditions in the placement of the syringe in the syringe pump, the pushing force of the pusher on the syringe and the engagement of the pusher drive mechanism. The syringe pump is provided with a clamp for holding the syringe in place and a device for preventing fluid from being siphoned out of the syringe. There is also a device for engaging and disengaging the motor drive mechanism. A position sensor senses the position of the syringe plunger in the barrel. A display graphically represents the syringe. Indicia are provided on the display to alert the user of conditions in the mechanism for holding the syringe in place, antisiphon device, the syringe drive engagement mechanism and the position of the plunger in the barrel.
