DUAL CHAMBER INJECTOR INTERGRATED WITH MICRO-NEEDLES

摘要

This invention relates to a medical injection system for the intradermal injection of two or more fluid substances via micro-needles, and most preferably via a linear array of micro-needles, although the array need not be linear. Injecting two fluid substances contained in two separate chambers of the delivery device can be done by various methods. These methods may be generally categorized as, a) sequential injection, b) simultaneous injection, c) parallel injection and d) closed-loop injection processes. The present invention includes devices configured to perform all three of these methods.
