Force-multiplying percussor and self-applicator system for airway clearance
First Claim
1. A system for airway clearance, comprising:
- a self-applicator assembly including a first strap overlaying and substantially co-extensive with a second strap, wherein the first and second straps are joined at their respective ends, and a pouch disposed between the first and second straps; and
a force multiplying percussor secured within the pouch of the self-applicator assembly, the force multiplying percussor comprising an anvil having a force-receiving surface and a force-delivering surface configured for contact with a patient'"'"'s body, a hammer having a force-receiving surface and a force-delivering surface, a housing and a thermal shell surrounding the hammer and not the anvil, wherein the housing and the thermal shell define an air gap therebetween, the hammer being attached to the anvil such that the force-delivering surface of the hammer and the force-receiving surface of the anvil are mechanically free to come together or move apart, a coil within the housing that causes the force-delivering surface of the hammer and the force-receiving surface of the anvil to separate when the coil is energized with an electrical current, a pulse generator that supplies repeated electrical current pulses to the coil, and a cooling fan for drawing air through the housing.

Abstract
An airway clearance combines a force multiplying percussor and a self-applicator assembly. The percussor has an anvil, a hammer, a coil, and a pulse generator. The anvil has a force receiving surface and a force delivering surface. The hammer also has a force-receiving surface and a force-delivering surface, and is attached to the anvil such that the hammer'"'"'s force delivering surface and the anvil'"'"'s force receiving surface are mechanically free to come together or move apart. When energized with an electrical current, the coil forces the hammer'"'"'s force delivering surface and the anvil'"'"'s force receiving surface to separate. The pulse generator supplies pulses of electrical current to the coil.
