Abstract
Abstract The invention relates to a medical dosing device for discharge of medicament for inhalation. The device comprise a handheld holder (2) for a medicine container (28;40) from which medicine is discharged via a valve (18;50;82) into an air channel (6) for inhalation air by means of initiation of an activation device (12;94). The valve is operationally connected with a control unit (14;90) arranged, on initiation of the activation device (12;94), to control the discharge valve (18;50;82) for intermittent opening and closing repeatedly within an inhalation period. The control unit is preferably an electronically controlled unit (14) which activates an electrically controlled discharge valve (18;50).
