Methods and apparatus for storing chemical compounds in a portable inhaler
View Patent ↗The invention provides exemplary aerosolization apparatus and methods for aerosolizing a substance. According to one exemplary method, a liquid is transferred from a first chamber into a second chamber having a substance that is in a dry state to form a solution. The solution is then transferred from the second chamber and onto an atomization member. The atomization member is operated to aerosolize the solution.
1. A method of aerosolizing a liquid, comprising the steps of:
electroforming a vibratable aperture plate made of palladium or a palladium alloy, the aperture plate having a front surface and a rear surface, the palladium or palladium alloy aperture plate being electroformed to form a plurality of tapered conical-shaped apertures extending from the rear surface to the front surface, the plurality of apertures being tapered to narrow from the rear surface to the front surface, the aperture plate further being formed to have a dome shape, mounting the vibratable aperture plate upon a support member wherein substantially all of a vibratable portion of the aperture plate not directly mounted to the support member comprises the dome shape:
providing a fluid at the rear surface of the aperture plate; and
vibrating the aperture plate to eject the fluid through the plurality of tapered conical-shaped apertures.
2. The method of claim 1 , wherein:
the electroforming step is carried out with the aperture plate being palladium cobalt.
3. The method of claim 1 , wherein;
the electroforming step is carried out with the aperture plate being palladium nickel.
4. The method of claim 1 , wherein:
the electroforming step is carried out with the aperture plate being about 80% palladium and about 20% nickel.
