A nasal medication delivery device

摘要

The invention relates to a delivery device for nasal medication. It addresses the need for delivering medication to the nose of a patient. In a preferred embodiment the device has: • A transducer 10 adapted to create an ultrasonic focal zone; • a feeder chamber 13 holding medication; • an energising chamber 14 smaller than the feeder chamber; • a mesh 15; and • an exit. The device is formed so that when it is activated the feeder chamber 13 continuously fills the energising chamber 14 with medication (until the feeder chamber has insufficient medication left to achieve this) so that there is a substantially constant supply of medication within the focal zone able to be energised and forced from the energising chamber so as to contact the mesh, become an aerosol, and leave the device by way of the exit.
