  • Patent number: 6488648
    Abstract: A powdered medicine multi-dose administering device has a medicine container unit (5b) for containing a unit-dose of medicine under the lower surface of the medicine storage chamber (5a) storing the medicine in a multi-dose amount. A medicine guiding unit (2) moves between a filling position and an administering position while maintaining a contact with the bottom surface. At the filling position, the medicine container unit is opened to the medicine storage chamber and is filled with the medicine. As the medicine container unit moves from the filling position to the administering position, the powdered medicine in the medicine container unit is swept and metered. At the administering position, the medicine in the medicine container unit is injected by the action of the pump unit (3) through a filter (6) and a pipe (2g, 2d, 2c).
