Abstract
An ultrasonic nebulizer is of the type having a piezoelectric transducer communicating with a fluid reservoir and is characterized by having a protective cover of a predetermined wavelength which is superimposed on the transducer, an elastomeric boot in surrounding relation to the cover to prevent fluid loss from the interface between the cover and transducer, and an oil coupling medium is disposed in the interface for coupling the ultrasonic energy from the transducer to the cover.
Claims10
In an apparatus for the nebulization of fluids in which a piezoelectric transducer is disposed in communication with a fluid reservoir for nebulizing liquid medication in the fluid reservoir, the improvement comprising:
- a protective cover member of a predetermined wavelength superimposed on said piezoelectric transducer, adjacent said reservoir said cover member and transducer having generally planar confronting surfaces and a common interface therebetween;
- annular sealing means in outer surrounding relation to said cover member for preventing the loss of fluid from said interface;
- and
- oil coupling means in said interface for coupling the energy from said transducer to said cover member.
