Aerosol generators with enhanced corrosion resistance
First Claim
1. An apparatus for generating an aerosol, comprising:
- a support member having a first face and a second face and defining an opening therethrough, wherein the support member comprises a first material having a first galvanic potential; and
an aerosolization element mounted on the support member and disposed substantially over the opening, wherein the aerosolization element defines at least one aperture therethrough, and wherein the aerosolization element comprises a second material having a second galvanic potential that is substantially equal to the first galvanic potential of the first material.

Abstract
An apparatus for generating an aerosol that includes a support member having a first face and a second face and defining an opening therethrough, where the support member includes a first material having a first galvanic potential, and an aerosolization element mounted on the support member and disposed substantially over the opening and defining at least one aperture therethrough. The aerosolization element may include a second material having a second galvanic potential that is substantially equal to the first galvanic potential of the first material. Also, a method of aerosolizing a liquid medicament by providing an aperture plate made of a first material and having a top surface and a bottom surface. The aperture plate is mounted on a support member that includes a second material that has an opening such that the aperture plate covers the opening, and where the first and second materials have similar galvanic potentials.

19. An apparatus for generating an aerosol, the apparatus comprising:
-
a support member having a first face and a second face and defining an opening therethrough, wherein the support member comprises a first material having a first galvanic potential;
an aerosolization element mounted on the support member and disposed substantially over the opening, wherein the aerosolization element defines at least one aperture therethrough, and wherein the aerosolization element comprises a second material having a second galvanic potential that is substantially equal to the first galvanic potential of the first material; and
a vibratory element in mechanical communication with the support member, wherein the vibratory element may be operated to vibrate to cause movement of the aerosolization element in such a manner that a liquid at a first face of the aerosolization element can be dispensed as an aerosol through the at least one aperture. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method of aerosolizing a liquid medicament, the method comprising:
-
providing an aperture plate made of a first material and having a top surface and a bottom surface, and also having a plurality of apertures, wherein the aperture plate is mounted on a support member comprising a second material that has an opening such that the aperture plate covers the opening, and wherein the first and second materials have similar galvanic potentials;
supplying the liquid medicament to the bottom surface of the aperture plate; and
vibrating the aperture plate to eject liquid droplets from the top surface of the aperture plate. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43)
