Portable ultrasonic nebulizer

A portable nebulizer for administering medication, the portable nebulizer comprising:

• a replaceable cartridge;
• a reservoir within the replaceable cartridge;
• a piezoelectric oscillator within the replaceable cartridge;
• the piezoelectric oscillator causing nebulization of liquid medication from within the reservoir, resulting in a mist that is discharged;
• the piezoelectric oscillator integrated into the replaceable cartridge, such that when the replaceable cartridge is replaced, the piezoelectric oscillator is also replaced;
• whereby replacing the piezoelectric oscillator when the replaceable cartridge is switched avoids cross-contamination of different liquid medications.

A portable device for administering medication via nebulization, the portable device including:

• a controller section;
• a battery within the controller section;
• a cartridge;
• the cartridge affixed to the controller section;
• a reservoir within the cartridge;
• a piezoelectric oscillator permanently affixed to the cartridge, whereby the piezoelectric oscillator is disposed of with the cartridge and controller when the reservoir has been emptied of medication;
• whereby the controller and cartridge are replaced simultaneously, avoiding cross-contamination and thus ensuring accurate dosing.
