ABSTRACT:
A processor driven syringe pump for one or more, typically two syringes, which are held vertically in corresponding pumping stations of a housing unit which itself is typically suspended from an IV pole. The pump features a central display having portions corresponding to each of the syringes operated by the pump. A data entry knob cooperative with a display processor, causes a cursor issue on the display to step through and choose the menu selections. A function knob is operative to select five operating states including: Purge, Setup, Stop, Run and Bolus in a virtual or software driven manner. The syringe holding station includes a pusher assembly having plunger clamp assembly and a load cell to measure force exerted on the plunger flange. An actuation pad and associated linkage provides for easy syringe flange capturing, while a syringe barrel clamp provides for easy syringe loading and secure syringe barrel positioning for many sizes of syringe. The pump operates in a rate, volume per time, or pharmacokinetic mode. The software provides a number of feedback warnings and alarms. The pump may be provided with a drug library. The syringe plunger is driven into the syringe barrel by a motor operated by a charge pump which provides a failsafe feature. The pusher assembly for the syringe includes a split nut that on actuation pad rotation releases to allow proper positioning of the syringe.
