USPTO Abstract

DRUG DELIVERY DEVICE WITH ELECTRONICS ABSTRACT An inhaler for delivering medication to a user. The inhaler may comprise a mouthpiece (106) comprising a flow pathway through which a dose medication is configured to be delivered to the user. The inhaler may comprise a mouthpiece cover (108) configured to prepare a dose of the medication such that the dose is available to the flow pathway for user inhalation as the mouthpiece cover (108) is moved to expose the mouthpiece (106). The inhaler may comprise an air vent coupled to the flow pathway, wherein the air vent is configured to provide a flow of air from the exterior of the inhaler to the flow pathway. The inhaler may comprise an electronics module (120) comprising a controller, a sensor, and a communication circuit. The sensor may be configured to generate a signal in response to an inhalation through the mouthpiece (106). The controller may be configured to generate a mouthpiece cover opening event in response to movement of a mouthpiece cover (108) of the inhaler from a closed position to an open position to make a dose of the medication available to the flow pathway and expose the mouthpiece (106), receive the signal from the sensor, generate an inhalation event in response to the signal indicating that a flow rate in the flow pathway exceeds a threshold, and cause the communication circuit to transmit the inhalation event and the mouthpiece cover opening event to an external device.
