Abstract
A deagglomerator apparatus and method are provided for deagglomerating material such as micron-sized, dry medicament powder (M). The deagglomerator apparatus includes a horn member (HM) having a tip portion (TP, TP1) wherein the tip portion defines a recess (R1) for holding the material. A vibrator mechanism is attached to the horn member and is operable for utilizing power from a generator (G) for vibrating the horn member, tip portion and recess wherein the recess vibrates at a frequency suitable for deagglomeration of agglomerated material held by within the recess. In a preferred embodiment, the material is held by a substrate which can be positioned at least partially into the recess. The deagglomerator apparatus and method can be used for deagglomerating material such that it includes particles of a respirable size, preferably less than approximately ten (10) microns (when referenced to unit density of 1 gram/cm.sub.3).
