Abstract
A medicator for a capsule filled with a powdered drug, comprising: a first member adapted to receive a capsule therein; a second member, having an air supply valve structure, arranged to communicate with the first member and arranged to operatively discharge air sucked from outside the medicator towards the first member in which a capsule is received; an air stream passage formed within the first member and the second member to direct air discharged from the air supply valve structure in a direction towards a capsule received by the first member; a third member removably attached to the first member to spray powdered drug in a capsule out of the medicator with air discharged from the air supply valve structure via the air stream passage; a drug trapping structure formed in the air stream passage to trap part of powdered drug contained in a capsule which falls down into the drug trapping structure; and a drug collecting structure formed in the air stream passage between the drug trapping structure and the air supply valve structure to collectively dam powdered drug from a capsule which falls in a direction opposite to the first member together with air when the air supply valve structure is in an intermediate state between a fully open state and a fully closed state, thereby preventing powdered drug from entering the air supply valve structure.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
