Solid state fluid delivery system

摘要

An apparatus and method are disclosed that utilize piezoelectric materials as part of a delivery system capable of the rapidly repetitive dispensing of a fluid to an intended target site. In a particular embodiment, the apparatus contemplates a needleless injection system which comprises a second housing structure, a plurality of piezoelectric elements which are stacked in a layered fashion within the second housing structure, electronic circuitry disposed proximate the second housing structure and hence the layered stack of piezoelectric elements, and a first housing structure containing a fluid reservoir operatively connected to the second housing structure so as to allow fluid contained with the fluid reservoir to communicate with the layered stack of piezoelectric elements. The layered stack of piezoelectric elements has at least one common aperture formed therein which extends therethrough.
