Abstract: An endonasal drug delivery device, suitable for inhalation, includes a shaped body having a first portion located at a first end of the shaped body, configured to be inserted in a nasal cavity and having an air delivery duct, a second intermediate portion having at least one air supply duct for allowing air to flow from the outside to the inside of the endonasal delivery device, and a third portion located at the opposite end of the first portion and having a mixing chamber, which is in fluid communication with the supply duct, a drug reservoir, and the delivery duct.

Abstract: A ventilation assembly includes an air intake channel; a delivery channel; a generating device of an air stream between the intake channel and the delivery channel; a filtering section of the air stream to decrease, if not eliminate, the presence of particulate in the air stream. The filtering section includes a filter having a containment body provided with an intake opening and a delivery opening for the air stream passing therethrough, and air-tight bulkheads, arranged inside the containment body and shaped to force the air stream to collide therewith and with the inner walls of the containment body, the bulkheads and the containment body having a section portion suitable for being penetrated by the particulate in the air stream so as to retain it therein.

Abstract: A nasal cavity filter (2) having a substantially cylindrical supporting wall (4), which adheres to the walls of a nasal cavity, and an inner surface (5) of which defines a cavity (6) for the passage of air inhaled and exhaled by the user. The cavity (6) houses a number of fins (7), which generate turbulence in the air flowing through, and the surface of which impacted by the air retains particles present in the air.
