Title: Medicament inhaler and method
Inventor: VILLAX PETER
IPC: A61M16/00
Filed: 1995-02-01
Abstract: A new inhalation device, which during operation causes an aerosol to be formed inside a chamber such as a capsule (4) which occludes one end (3) of the inhalation tube (1), the capsule having holes at its extremities (7,8) which admit airflow. The airflow causes the powder contained inside the capsule to be surprisingly transported to the capsule extremity contrary to the direction of inhalation, that is towards the air entry holes in the capsule, and then to form an aerosol until all powder has been removed from the capsule or chamber through the tube (1), the duration of inhalation being chiefly regulated by the size and proportion of the capsule holes. The tube (1) has air inlets downstream of the capsule to permit a balanced airflow that will transport the finely suspended powder into the lungs, maximising the fraction of medicament deposited therein.
