Publication number: 20070017511Abstract: Medicine powder is prevented from adhering to the tongue and the like when the medicine powder is being inhaled, discomfort due to the sense of taste is relieved, and a prescribed amount of medicine powder is enabled to be administered efficiently. With regard to a long mouthpiece 16, the length L of its held-in-the-mouth area 16C to be held in the mouth 19 is set at approximately 80 mm. This enables one end of the held-in-the-mouth area 16C to be inserted deep into the oral cavity 22 when the held-in-the-mouth 16C is held in the mouth 19. Accordingly, the medicine powder can be discharged in a position beyond sweetness sensing parts 24A, saltiness sensing parts 24B, sourness sensing parts 24C and bitterness sensing parts 24D of the tongue 24. Thereby, a patient can inhale the medicine powder comfortably without sensing bitterness, sourness, sweetness and the like of the medicine powder.Type: ApplicationFiled: May 14, 2004Publication date: January 25, 2007Inventors: Hisatomo Ohki, Shigemi Nakamura, Kazunori Ishizeki, Akira Yanagawa
