Liquid medicine ejection device

Abstract

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.
