Patent abstract
A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug deliver pump.
