Abstract
A portable insulin delivery device that supplies insulin in a pre-pressurized chamber, passes the insulin through a pressure-dropping labyrinth to a flow control valve. The valve is activated by a piezoelectric actuator. This allows for precise insulin delivery. An electronic package provides for programming of basal rates and bolus. A pressure sensor relays data concerning normal operation and pressure changes that indicate problems. The processor, keypad, display, power source, fluid pressure sensor and fluid flow control actuator are housed in a base unit. A removable cartridge unit houses the pre-pressurized fluid reservoir, flow path labyrinth, and flow control valve.
