Abstract
A device for the transnasal or oral administration of drugs or similar media, comprising a finger-like applicator (3) which has a spray nozzle (6) disposed at its free end and includes a cylinder unit (1) for accommodating the medium to be administered. The medium is applied by moving a piston (7) into the cylinder unit (1). A membrane-like seal (4) is located between the cylinder unit and spray nozzle and is slotted to open and form a fluid passage under pressure. The cylinder unit may be built into the applicator or may include a separate cartridge releasably mounted in the applicator. The piston may be activated in steps or in a continuous motion. A second applicator may be attached to the side of the first applicator with the spray nozzles located generally in accordance with spacing of human nose nostrils.
