Abstract: An inhaler includes an inhaler body having an ejection head and an airflow duct forming member for forming an airflow duct on the inhaler body. In an inhalation standby status, the airflow duct forming member is driven to slide so as to be placed at rest on the inhaler body to partly cover the top part of the latter by means of a slide mechanism and make the airflow duct disappear. At this time, the top wall of the airflow duct forming member covers the ejection head to shield it from external air. In an inhalation status, the airflow duct forming member is driven to slide up and produce an airflow duct on the inhaler body. Thus, a compact inhaler that can be switched from an inhalation status to an inhalation standby status and vice versa with ease is realized.

Abstract: In a medicine ejection device for administering a medicine to the throat, bronchi or lungs, the air flow path to which the medicine has stuck is to be kept in clean state in a simple configuration. The medicine ejection device which ejects a medicine to be inhaled by a user via a suction port, including a flow path member linked to the suction port and capable of forming an air flow path in which the medicine is guided by the inhalation by the user to the suction port, and an internal wall face constituting member which is intended for formation of the internal wall of the air flow path and allows detachable fitting in the flow path member.
