<p>The piezoelectric dual-syringe insulin pump (10) includes a single piezoelectric motor (15) configured to pump insulin. The pump is controlled by a single controller (302). The pump (10) uses two insulin reservoirs (16a, 16b) (in the form of two syringes), one of which is filled with a rapid-acting insulin, the other reservoir being filled with slow-acting insulin (providing the basal function). Both syringes (16a, 16b) are alternately actuated by a single PZT linear motor (15) (particularly, a squiggle motor), depending upon polarity of the voltage applied to the motor (15), and feed into a common infusion line to the patient. The device (10) includes an LCD display (308), audio alarm (310), controller, keypad (306), USB port (312), and a micro-energy harvesting circuit (316) for recharging an on-board battery (314).</p> |
