Abstract
A medical inhaler generates an aerosol of pharmaceutically effective medication to be absorbed by the respiratory tract of a patient includes a reservoir (1) of liquid medication, a conveyor (2) to expel the liquid from the reservoir, an atomizing vibrator (3) and a feed line (4) to conduct the liquid between the reservoir and the vibrator. The conveyor and the vibrator can be controlled by a process controller (15) which can include a microprocessor. Discharge of liquid medicine is both coordinated with the vibrator and accurately dosable and achieves optimal atomization of the medicine.
Claims15
A medical inhaler to generate an aerosol of a pharmaceutically effective medication to be absorbed in the respiratory tract of a patient comprising the combination of
- a reservoir (1) containing a liquid medication;
- a dosing unit including means movable within said reservoir;
- a conveyor (2) to activate said dosing unit for expelling said liquid medication out of said reservoir (1),
- an atomizing vibrator (3);
- a feed line (4) for conducting said liquid medication from said reservoir (1) to said vibrator (3);
- and
- process control means (15) for controlling and coordinating operation of said conveyor (2) and said atomizing vibrator (3).
