There is provided a liquid formulation ejection device which improves reliability of inhalation even in a case where a preejection is performed and resolves a concern about hygiene. The liquid formulation ejection device (1) ejects a liquid formulation in a form of liquid droplets into an inhalation flow path (20) and allows a user to inhale the formulation. The liquid formulation ejection device (1) includes an ejector (11) for performing normal liquid droplet ejection for inhalation and liquid droplet preejection not for inhalation, and a discharger (13, 14, 28) for removing liquid droplets ejected by the liquid droplet preejection out of an inside of the inhalation flow path (20).
L~invention concerne un dispositif d~éjection de formulation liquide permettant d~assurer une inhalation plus fiable et hygiénique même en cas d~éjection préalable. Le dispositif d~éjection de formulation liquide (1) éjecte une formulation liquide sous forme de gouttelettes liquides dans un passage d~inhalation (20) et permet à un utilisateur d~inhaler la formulation. Le dispositif d~éjection de formulation liquide (1) comporte un éjecteur (11) assurant une éjection normale de gouttelettes liquides à inhaler ainsi qu~une éjection préalable de gouttelettes liquides qui ne sont pas inhalées ; et un élément d~évacuation (13, 14, 28) servant à évacuer de l~intérieur du passage d~inhalation (20) les gouttelettes liquides éjectées lors de l~éjection préalable de gouttelettes liquides.
