Aerosol inhalation device

Claim 1

Aerosol inhalation device having one storage position and one dosage dispensing position for use at inhalation of uniform doses of a finely divided drug in the form of an aerosol, comprising a socket (1) for an exchangeable aerosol container and an elongated deceleration chamber (2, 3) connected to the socket, said chamber having a mouthpiece (4) in its opposite end and intended to be connected to the mouth of a patient; the chamber comprises two chamber parts, each having a substantially rectangular cross section, of which an outer chamber part (3) comprises the mouthpiece (4) and is telescopically displaceable over an inner chamber part (2) which is provided with a flexible tongue (5) at the end being adjacent the mouthpiece, which tongue on telescoping the device together will close the mouthpiece, characterized by that the socket (1) for the aerosol container a) has a substantially rectangular cross section and can be telescopically inserted into said inner chamber part (2) to a storage position, b) is tapered by a sectional arch in the end being adjacent the chamber and is provided with grooves (16; 16', 16", 16"') alongside its four longitudinal edges, which grooves are each terminated with a stop lug (17, 17', 17", 17'") which in the dosage dispensing position catch with stop lugs (18, 18', 18", 18"') in the inner chamber part (2) so that the socket (1) can be extracted from said chamber part (2) and be pivoted in a fixed angle relative the longitudinal axis of the chamber part (2) to assume the dosage dispensing position, and c) is provided with means for locking the socket (1) in said fixed angle.
