An improved inhaler and medicated packet which uses a patient's breath to send powdered medication into the oral cavity of the patient. The inhaler is reusable and controls both the rate of airflow inside the chamber and prevents the patient from blowing into the inhaler. Disposable medicated packets are inserted into the inhaler. These medicated packets have preformed holes which pass air through the packet and entrain the medication. One inhaler can be used numerous times for numerous different types of medication. These medicated packets have a removable, protective layer to maintain the sterility and dryness of the measured dose of medication. In operation, the medication is transported from the packet, through the inhaler, and into the patient. The medicated packets are transparent on one side to allow the patient to observe if the medication has been completely delivered.
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.
