title: A portable insulin infusion system with a rotary solenoid-driven peristaltic pump.
abstract: A portable, external, preprogrammed insulin infusion system with a mass of 560 grams and a battery lifetime of 4 months is described. The system uses a rotary solenoid-driven peristaltic pump, with low-power CMOS timing circuitry and controls to provide bimodal insulin delivery with a timed high rate. Accurate and reproducible delivery of 2 microliter fluid pulses at programmed intervals from 0.6 seconds to 100 minutes can be achieved permitting the delivery of a wide range of insulin concentrations. This system is the precursor to a totally implantable insulin delivery system.
