<p>A syringe pump (8) is disclosed, having a housing (10), a motor driven pusher (14) for pushing the plunger of a syringe and various transducers (35,36,38,40,42) 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 (16) for holding the syringe in place and a device (20) 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 (35) senses the position of the syringe plunger in the barrel. A display (26) graphically represents the syringe. Indicia (30,32,34) 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. <IMAGE></p> |
