Abstract
In a method for performing an inhalation a reservoir is filed with a medication fluid or a medication container is connected to a designated connecting piece, a nebulizer unit is connected to a control unit and a mouthpiece, the nebulizer unit is activated, the medication fluid is atomized into a fine particulate aerosol which is emitted into an aerosol chamber formed by the nebulizer unit and the mouthpiece, and an inhalation is performed by a user. A pressure within the aerosol chamber and/or a flow rate through the aerosol chamber is measured using the control unit. The nebulizer is activated with each breath on occurrence of at least one activation criterion detected using the control unit. The nebulizer unit is deactivated with fulfillment of at least one stop criterion.
Claims14
A method for performing an inhalation using a nebulizer, comprising:
- filling a reservoir with a medication fluid or connecting a medication container to a designated connecting piece,
- connecting a nebulizer unit to a control unit and a mouthpiece,
- at least temporarily activating the nebulizer unit,
- atomizing the medication fluid into a fine particulate aerosol which is emitted into an aerosol chamber formed by the nebulizer unit and the mouthpiece during activation of the nebulizer unit,
- performing the inhalation, with a user enclosing the mouthpiece with the lips and during inhalation, drawing air from outside into the aerosol chamber, where the air mixes with the aerosol, and then passes further through the mouthpiece as an air stream and into the respiratory tract and, possibly into the user's lung,
- measuring a pressure within the aerosol chamber and/or a flow rate through the aerosol chamber or the mouthpiece using the control unit,
- activating the nebulizer unit with each breath on occurrence of at least one activation criterion detected using the control unit, and
- deactivating the nebulizer unit with fulfillment of at least one stop criterion.
