Multi-dose powdered medicine administering device and method thereof

An inhalation type feed method for feeding multi-dose powdered medicine to be administered, comprising the steps of:

• attaching a storage chamber (3) for storing powdered medicine, the amount of which corresponds to a plurality of times of administering operations, to a device body (1);
• moving a quantitative medicine dispensing means (6) having an accommodation chamber (10), the capacity of which corresponds to a single administering operation, to a charging position at which said accommodation chamber is communicated with said storage chamber;
• stirring the powdered medicine in said storage chamber by injecting air into said storage chamber through said accommodation chamber at the charging position;
• charging the powdered medicine, the amount of which corresponds to a single administering operation, from said storage chamber into said accommodation chamber by the action of gravity and/or suction force;
• and moving said dispensing means (6) so that the accommodation chamber (10) charged with the powdered medicine can be conveyed to the administering position.

A spraying type feed method for feeding multi-dose powdered medicine to be administered, comprising the steps of:

• attaching a storage chamber (3) for storing powdered medicine, the amount of which corresponds to a plurality of times of administering operations, to a device body (1);
• moving a quantitative medicine dispensing means (6) having an accommodation chamber (10), the capacity of which corresponds to a single administering operation, to a charging position at which said accommodation chamber is communicated with said storage chamber;
• stirring the powdered medicine in said storage chamber by injecting air into said storage chamber through said accommodation chamber at the charging position;
• charging the powdered medicine, the amount of which corresponds to a single administering operation, from said storage chamber into said accommodation chamber by the action of gravity and/or suction force;
• moving said dispensing means (6) so that the accommodation chamber (10) charged with the powdered medicine can be conveyed to the administering position;
• and injecting air into said accommodation chamber at the administering position so that the powdered medicine, the amount of which corresponds to a single administering operation, is sprayed outside the device body.

A quantitative feed device for quantitatively feeding powder comprising:

• a device body (1);
• a storage chamber (3) detachably provided to said device body, the capacity of which corresponds to a plurality of times of feeding operations;
• an accommodation chamber (10), the capacity of which corresponds to a single time of feeding operation;
• a quantitative dispensing means (6) movably attached to said device body for movement to a charging portion and a feeding position so that the powdered medicine can be supplied to the accommodation chamber when the accommodation chamber is communicated with the storage chamber at the charging position (3a) and the accommodation chamber is communicated outwardly of the device body (1) at the feeding position (5a);
• means (20, 21) for moving said dispensing means between the charging and feeding positions;
• and a pump means (8) for stirring the powder in the storage chamber by injecting air into said storage chamber through said accommodation chamber, wherein a predetermined amount of stirred powder is charged from said storage chamber to said accommodation chamber by the action of suction force generated by said pump means and/or the action of gravity.
