Abstract
A capsule holder 2 of a medicine administering device 1 for nasal cavities comprises a movable member 8 which is axially movable, and a fixed member 3, in which the movable member 8 is formed at its outer periphery with an external thread 8D which is to be threadedly engaged with an internal thread 19C of a medicine spraying section 19. An air inflow hole H is formed by a perforating end 27A of a pin 27 when a capsule K is thrust into a one-side capsule hole 11, while the movable member 8 is raised so that the perforating end 27A is extracted from the air inflow hole H1 when the capsule holder 2 and the medicine spraying section 19 are incorporated with each other. An air outflow hole H2 is formed by a pin 28. A perforating tool is housed in the medicine administering device 1, in which a hole formation action for the air inflow hole H1 is also made during installation of the capsule K. The whole body can be made compact since the longitudinal dimension of the pin 27, 28 is decreased while the outer peripheral surface of the capsule holder 2 is covered with a pump section 15.
