1. A device for administering drug to a patient by inhalation, comprising:
- (a) an inhaler comprising;
(i) an adapter for connecting to a drug reservoir and which channels the flow of medication from said drug reservoir into a flow chamber;
(ii) said flow chamber which receives medication from said adapter and which additionally has a fresh air inlet;
(iii) a mouthpiece connected to said flow chamber and which is capable of delivering drug outside said device;
(b) a use sensor connected to a microprocessor by an electrical circuit and which transmits an electrical signal to said microprocessor in response to drug administration;
(c) a microprocessor connected to said use sensor by said electrical circuit and which, in response to said electrical signal, records the time of said signal and which is electrically connected to a wireless transmission device;
(d) a wireless transmission device, connected to said microprocessor and which, in response to electrical signals from said microprocessor, transmits radio frequency waves; and
(e) a battery compartment which is electrically connected to one or more of said use sensor, microprocessor and wireless transmission device and which has contacts for receiving electrical input from one or more batteries.

Abstract
The present invention is directed to a device for monitoring the usage of inhaled drugs by a patient. The device includes an inhaler, a use sensor, a microprocessor, a wireless transmitter and a battery compartment. These components allow information concerning drug usage to be transmitted to health care personnel that can evaluate the data to determine whether there are changes in drug usage characteristics that are indicative of an impending acute attack. The invention includes not only the device, but also the systems and methods in which the device is employed.
