<p>Atomizing dispenser for endonasal spray administration of drug solutions, comprising a main body or slider (1), a piston/pump (12) axially slidable into a drug container (5) and a housing/button (3), characterized in that as a specific feature of the invention, the piston/pump (12) is provided on its stem (4) with two grooves/seats (6) and (7) each retaining the resilient detent rings (8) and (9), which oppose and control the piston/pump (12) run. Said control being exerted by obliging to accumulate enough energy in the user's hand to force the resilient detent rings (8) and (9) to expand and to snap out from their grooves/seats (6) and (7), one after the other one, thus fractioning the piston (12) run and the consequent atomized delivery into two separate deliveries which can be administered one for each user's nostril, said snap allowing an instant release of the accumulated energy on the piston/pump (5) with the consequent servo-assisted perfect atomization of the drug solution.</p> |
