Breath-controlled inhalation therapy device
First Claim
1. Breath-controlled inhalation therapy device for the provision of an aerosol for use by a patient as part of an inhalation therapy, said device comprisinga housing that defines a nebulisation area,a nozzle opening for the entry of a pressurised gas, preferably compressed air, into the nebulisation area,at least one outlet opening for the entry of a liquid to be nebulised, preferably a therapeutically effective liquid, into the nebulisation area,a closing means for closing the nozzle opening, which is arranged in the nebulisation areas relative to the nozzle opening such that the closing means can be moved into a position closing the nozzle opening and into a position exposing the nozzle opening, andan actuation device for actuating the closing means in response to the respiratory cycle of the patient so as to actuate the closing means during the exhalation phase of a respiratory cycle of the patient such that the closing means assumes the position closing the nozzle opening.

Abstract
A breath-controlled inhalation therapy device includes an obturation mechanism, obturating a nozzle opening through which a pressurized gas, preferably pressurized air, is issued when the device is in operation. An actuation mechanism actuates the obturation mechanism only in the exhalation phases of the respiration cycle of a patient. The fluid to be atomized is therefore substantially atomized only in the inhalation phases.
