  • Patent number: 5341801
    Abstract: An inhaler for delivering metered doses of a particulate drug. The inhaler is formed of a housing, a drug reservoir attached to the housing to contain multiple doses of the particulate drug, a drug transporting slide in the housing that contains a metering chamber of volume corresponding to a desired dose of the drug, and a vacuum pump that creates a partial vacuum in the metering chamber. The drug transporting slide is movable from a load position, in which it communicates with the drug reservoir to receive in its metering chamber drug from the drug reservoir, to a release position in which it communicates with an air outlet passage to release drug from the metering chamber into the air outlet passage. The drug reservoir has an air permeable portion that permits air flow into the drug reservoir but prevents drug escape. In use, the vacuum pump draws a dose of drug into the metering chamber. The drug transporting slide then moves to deposit the drug in the outlet passage for inhalation.
