A liquid medicine ejection device for ejecting a liquid medicine as liquid droplets to be inhaled by a user includes means for providing information on the ejection to the user without providing means for determining a state of the ejection when a preliminary ejection operation is carried out, the preliminary ejection operation ejecting an amount of the liquid medicine smaller than an amount ordinarily ejected. The liquid medicine ejection device enables improved reliability of ejection and comfort of a user by carrying out preliminary ejection before inhalation and by making it possible for the user to visually or auditorily check an ejection state of minute liquid droplets with a relatively simple structure to see whether or not the preliminary ejection is carried out correctly.
L~invention concerne un appareil permettant l~éjection d~un médicament liquide sous forme de gouttelettes liquides à inhaler par un utilisateur et contenant un moyen de fournir à l'utilisateur des renseignements sur l'éjection sans offrir de moyen de déterminer un état d'éjection lors d~une opération préliminaire d'éjection, l~opération préliminaire d'éjection projetant une quantité de médicament liquide plus petite qu'une quantité ordinairement projetée. L'appareil d~éjection de médicament liquide améliore la fiabilité de l'éjection et le confort d'un utilisateur en effectuant une éjection préliminaire avant l~inhalation et en permettant à l'utilisateur de vérifier visuellement ou auditivement un état d'éjection de toutes petites gouttelettes de liquide au moyen d~une structure relativement simple permettant de vérifier si l'éjection préliminaire s~est effectuée correctement ou pas.
