Nasal medication delivery device

A delivery device for nasal medication, the device comprising:

• a mouthpiece to contact a mouth of a user;
• a breath sensor;
• an ultrasonic energy generator comprising a concave transducer;
• a feeder chamber holding medication;
• an energizing chamber smaller than the feeder chamber;
• a mesh;
• and
• a nasal prong;
• wherein when the device is activated:
• the concave transducer causes ultrasonic energy to travel toward the mesh and create a tapered focal zone of concentrated ultrasonic energy within the energizing chamber such that a charge of the medication in the energizing chamber is energized and forced from the energizing chamber so as to contact the mesh to become an aerosol and leave the device by way of the nasal prong;
• the feeder chamber replenishes the energizing chamber with the medication so that the energizing chamber has a substantially constant charge of the medication therewithin, but wherein when the feeder chamber is empty and the energizing chamber has an insufficient amount of medicine from the feeder chamber to be energized and delivered via the nasal prong this insufficient amount is wastage, and wherein the smaller size of the energizing chamber relative to the feeder chamber serves to substantially limit the wastage;
• and
• the breath sensor detects a user blowing into the mouthpiece and in response thereto causes the medication in the energizing chamber to be energized while the mesh oscillates to produce a micro-pumping action to assist in creating the aerosol.

A delivery device for nasal medication, the device comprising:

• an ultrasonic energy generator that creates a tapered ultrasonic focal zone of concentrated ultrasonic energy;
• an ultrasonic energy transmission medium;
• an energizing chamber holding medication at the tapered ultrasonic focal zone, wherein the energizing chamber is remote from the ultrasonic energy generator;
• a feeder chamber larger than the energizing chamber and capable of holding more of the medication, wherein the feeder chamber continuously fills the energizing chamber with medication so that there is a substantially constant supply of the medication within the tapered ultrasonic focal zone;
• a mesh;
• and
• a nasal prong;
• wherein the feeder chamber detachably cantilevers outwardly from one side of the device at a location between the nasal prong and the ultrasonic energy generator;
• and
• wherein when the device is activated:
• ultrasonic energy travels through the ultrasonic energy transmission medium towards the tapered ultrasonic focal zone;
• and
• the medicine within the tapered ultrasonic focal zone is energized and forced from the energizing chamber so as to contact the mesh, become an aerosol, and leave the device by way of the nasal prong.
