ABSTRACT:
An inhaler device having a pump unit (P) for producing a stream of compressed air, a drive (G) for the pump unit and a nebuliser unit (Z) which communicates with the pump unit and which is driven pneumatically. The inhaler device produces and releases an air stream which is charged in controlled manner with fine liquid active ingredient particles. The pump unit (P) is equipped with a short-stroke piston pump. The drive takes the form of a crank gear (G) having a gear transmission which can be driven by means of a hand crank (K), the output shaft of which is kinematically connected to the pump piston via an eccentric and drives the pump piston. The inhaler device need not use any elaborate energy supply and can be built in compact and handy fashion. It can be ready for use anytime and anywhere and is therefore particularly suitable for mobile use.
