Abstract :
A miniature piezoelectric pump and valves with electronic controls for programmed release of insulin is described. The pumping volume and pressure as a function of voltage are calculated and experimentally verified. The volume pumped per stroke is 19 μcc/V and pump pressure is l mm-Hg/V. The pumping rate can be varied from one stroke per second to any slower rate and is controllebdy a quartz crystal oscillator. Pump and valve driver circuits are given.
