Abstract
A drug delivery system for automatically dispensing a pre-set dosage of a drug agent or medication. The drug delivery system generally includes a housing including one or more reservoirs; each having a medical agent hermetically sealed therein. A membrane extends across each of the one or more reservoirs which is adapted to allow the medical agents to pass therethrough in response to external stimuli, such as physical puncturing, melting the membranes through use of heating elements or electrowetting in response to a voltage pulse. A wicking material extends across the membranes through which the medical agents are dispensed to a patient. Because the housing can be made flat, the overall dispensing device can be reduced in size, allowing the drug delivery device to be located and attached to broader areas of the patient's body for expanded medical applications and treatment.
