Abstract
A syringe pump comprises a housing with a syringe retainer. The syringe includes a barrel for liquid medication and a plunger movably positioned in the barrel for expelling the medication. A driver is movably mounted on the housing for engagement with the plunger. A control mechanism within the housing regulates the rate of movement of the driver and plunger during delivery of medication. A monitoring circuit connected to receive signals from a potentiometer and a movable contact associated with the driver indicates driver motion. A microprocessor with memory includes a preset standard to which the signal of motion from the driver is compared. An additional input signal, of motion from a rotary indicator associated with a part of the driver movement motor assembly, is provided to the memory and is compared to plunger travel into the barrel.
