Publication number: 20060231096Abstract: A mouthpiece 15 is configured to be provided with a plurality of air nozzles 22 which are positioned around an admission port, and from which the air to enclose the surroundings of medicine powder flow discharged from the admission port 20 is blown off. Accordingly, when the breath is inhaled while an outer body 21 of the mouthpiece 15 is being held in the mouth, the air to be blown off from the air nozzles 22 forms an air curtain 24 to enclose the surroundings of the medicine powder flow 23 discharged from the admission port 20. Thereby, medicine powder included in the medicine powder flow 23 is prevented, by the air curtain 24, from adhering to the surface of the tongue, the internal surface of the oral cavity and the like. Thus, the medicine powder can be inhaled comfortably while unnecessary taste of the medicine powder such as sweetness, saltiness, sourness, bitterness and the like, is not being sensed.Type: ApplicationFiled: May 14, 2004Publication date: October 19, 2006Applicants: Hitachi, Ltd., Dott Limited CompanyInventors: Hisatomo Ohki, Shigemi Nakamura, Kazunori Ishizeki, Akira Yanagawa

Patent number: 5996577Abstract: 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.Type: GrantFiled: August 9, 1996Date of Patent: December 7, 1999Assignees: Unisia Jecs Corporation, Dott Limited CompanyInventors: Hisatomo Ohki, Shigemi Nakamura, Kazunori Ishizeki, Akira Yanagawa
