摘要：
A bladder arrangement is provided for a microneedle-based drug delivery device. The bladder arrangement includes a flexible membrane having an inner surface, an outer surface and an outer periphery. A bladder member, having a rigidity greater than the flexible membrane, includes an inner surface, an outer surface and an outer periphery. The inner surface of the flexible membrane and the inner surface of the bladder member define a chamber for receiving a drug therein. At least one microneedle is operatively connected to the bladder member. The at least one microneedle has an input and an output receivable within the individual. A valve operatively connects the input of the at least one microneedle and the chamber.
