Title:
INHALATOR AND PERTAINING ATOMIZER
Document Type and Number:
WIPO Patent Application WO2002024262
Kind Code:
A3
Abstract:
The invention relates to an inhalator comprising a pump unit (P) that generates a pressurized airflow, a drive (G) for said pump unit and an atomizer (Z) that is operated with pressurized air and that communicates with the pump unit. Said atomizer generates and releases in a dosed manner an airflow that is charged with fine liquid particles of an active substance. The pump unit (P) is provided with a short-stroke piston pump. The drive is configured as a crank mechanism (G) that comprises a reduction gear that is driven by means of a crank (K). The output shaft of said gear is kinematically linked with the pump piston via an eccentric, thereby driving the pump piston. The inhalator has a compact design and is easy to handle and requires no complex energy supply. It is operational at any time and anywhere and is therefore especially useful for mobile applications.
