초록 ▼

A dispensing apparatus comprising a reservoir for providing a medication under pressure and a housing which has a centrally located chamber and a wave shaping chamber located in a front portion of the housing. Positioned between the wave shaping chamber and the centrally located chamber is a blast valve. The plunger of a reciprocating piston has a vertical extending support member attached its front end. A power supply provides a square wave signal at a predetermined frequency to a coil alternatively energize and de-energize the coil. When the coil is energized the piston moves rearward. De-energizing the coil results in forward movement of the piston. A plurality of inlet ports positioned around the housing between an inlet manifold coupled to the reservoir and the centrally located chamber allow the medication to enter the chamber as a medicated vapor when the piston is drawn rearward. An impact head attached to the piston unseats the blast valve when the piston moves forward allowing medicated vapor to enter the wave shaping chamber. An edged shaped orifice at the front end of the housing communicates with the wave shaping chamber allowing medicated vapor to exit the wave shaping chamber and pass through the edged shaped orifice to form a ring vortex of medicated vapor. The blast valve opens and closes at the predetermined frequency causing the aerosol dispensing apparatus to generate a train of the ring vortices of medicated vapor.
