Abstract
An improved drug dispenser for the pulsatile or peristaltic delivery of drugs. The drug dispenser includes a fluid reservoir for storing the drug to be dispensed, an electrochemical pump for pumping the drug from the fluid reservoir, and a pump valve responsive to the pump pressure such that when the pump pressure reaches some predetermined value, the pump valve releases the pressure exerted upon the drug. The result is a low cost, low weight ad efficient drug dispenser for the pulsatile delivery of drugs.
