A portable insulin infusion system with a rotary solenoid-driven peristaltic pump. 1980

G A Carlson, and J T Love, and R S Urenda, and W J Spencer, and R P Eaton

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.

D007328	Insulin	A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
