An intranasal atomizer drug chamber housing comprises an atomizable liquid, an atomizer chamber; a slidable plunger; an atomizer in the atomizer chamber and a spring to drive the plunger upon release from a compressed position. The intranasal atomizer may additionally comprise: a drug chamber veil attached to outlet end of the atomizer, and shaped to fit in a user's nostril. A trigger housing comprising a trigger button and a trigger mechanism may be attached to the drug chamber housing. The trigger mechanism retains the spring in a compressed position, and releases the spring to drive the plunger upon activation of the trigger button. A safety cap fits over the outlet end of the drug chamber housing and has a flexible arm to insert within the trigger mechanism to prevent the release of the spring. A method of providing an atomisable drug or medicament using the intranasal atomizer is also disclosed. |
