摘要

A piercing device for use in internally pierced blister delivery devices include a base, a piercer body and an internal fluid path. The internal fluid path includes one or more inlet channels into a central cavity which is connected to one or more delivery channels and exit ports. The cavity is defined by angular walls and top to create turbulence in the fluid flow and to produce a controllable spray, mist, drops, plume or stream delivery. The piercer body also provides a pointed lancet disposed in the center of the exit ports for piercing the lidstock of a formed blister.
