Abstract: An inhalator including an inhalator body including a powder receiving chamber for receiving a powder, an air-powder mixture reservoir for temporarily storing an air-powder mixture flowing from the powder receiving chamber, and a diluent air passage for introducing a diluent air into the air-powder mixture reservoir. The air-powder mixture is formed within the powder receiving chamber when an air is introduced into the powder receiving chamber. The air-powder mixture within the air-powder mixture reservoir is admixed with a diluent air introduced thereinto through the diluent air passage. The diluted air-powder mixture is discharged from an air-powder mixture outlet into a user's oral or nasal cavity. A powder composition for inhalators includes at least two kinds of fine particles different in particle diameter.

Abstract: An inhalant medicator includes a medicator body 1 which is formed therein with a cylindrical fit hole 2, an inhalant port 3, an inflow air passageway 5, and an outflow air passageway 6, and a medical powder storage cylindrical member 8 which is installed or fitted into the cylindrical fit hole 2 in a manner so as to open or close the air passageways 5 and 6 with respect to a medical powder storage chamber 12. The inhalant medicator is constructed by two component parts, namely the medicator body 1 and the medical powder storage cylindrical member 8, thus ensuring simplified structure and reduced production costs. Additionally, powder-and-granular medicine or medical powder 16 is tightly encapsulated within the medical powder storage chamber 12 by means of the medical powder storage cylindrical member 8, thus preventing loss of flow of the medical powder 16.

Abstract: A medicine administering apparatus, suitable for administering granular medicine to a patient, comprises a main body which has a medicine passage and a medicine accommodating chamber. The apparatus further includes a location changing member formed with a medicine loading chamber. The location of the medicine loading chamber is changed between a first position, where the medicine loading chamber is separate from the medicine passage, and a second position, where the medicine loading chamber is in the medicine passage. Movement of the location changing member changes the position of the medicine loading chamber. A medicine loading member compresses a predetermined amount of the medicine into the medicine loading chamber at the first position, the predetermined amount corresponding to one dose. Medicine within the medicine loading chamber may be inhaled through the medicine passage by a patient when the patient breathes in.

Abstract: A medicine administering device for nasal cavities, comprising a capsule holding section formed with a capsule containing powder-state medicine. An air supply section is connected to the lower end of the capsule holding section and formed with an air supply passage which is in communication with the capsule accommodating chamber. A branched passage section is connected to the upper end of the capsule holding section and has an air flow passage in communication with the capsule accommodating chamber. The air flow passage is bifurcated to form first and second outlet passage portions which are arranged to form a generally Y-shape. First and second medicine passages are formed such that air from the branched passage section flows therethrough to carry the medicine in the capsule into right-side and left-side nasal cavities of a patient. The first and second passages are respectively in communication with the first and second outlet passages of the branched passage section.

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.
