Title:	Compliance monitoring module for a breath-actuated inhaler
Abstract:	A compliance monitoring module for a breath-actuated inhaler comprising: a miniature pressure sensor, a sensor port of said sensor being pneumatically coupled to a flow channel through which a user can inhale; a processor configured to: receive a signal originating from a dosing mechanism of the inhaler indicating that medication has been released; receive data from a sensing element of the sensor; and based on said signal from said dosing mechanism and said data from said sensing element, make a determination that inhalation of a breath containing medication through said flow channel complies with one or more predetermined requirements for successful dosing; and a transmitter configured to, responsive to said determination, issue a dosing report.

Patent Claims:	1. An inhaler comprising: a hopper comprising medicament; a dosing chamber; a mouthpiece; a cover; a monitoring module comprising a sensor, a wireless transmitter, and a processor; and a bellows, wherein the bellows is configured to compress upon movement of the cover to expose the mouthpiece, and wherein the compression of the bellows causes: a dose of the medicament to be metered from the hopper into the dosing chamber; and the monitoring module to change from a first power state to a second power state. 2. The inhaler of claim 1, wherein the sensor comprises a pressure sensor. 3. The inhaler of claim 2, wherein the pressure sensor comprises a microelectromechanical system (MEMS) pressure sensor or a nanoelectromechanical system (NEMS) pressure sensor. 4. The inhaler of claim 1, wherein the first power state is associated with a first power consumption and the second power state is associated with a second power consumption; wherein the first power consumption is different than the second power consumption. 5. The inhaler of claim 1, wherein the first power state is an off state or a sleep state, and the second power state is an on state. 6. The inhaler of claim 1, further comprising a yoke connected to the cover, wherein the yoke is configured to activate the sensor when the cover is moved to expose the mouthpiece, and wherein the activation of the sensor changes the monitoring module from the first power state to the second power state. 7. The inhaler of claim 1, further comprising a spring, wherein, when the cover is moved to expose the mouthpiece, the bellows and the spring are configured to move in a direction away from the sensor, wherein movement of the spring and bellows actuates the sensor to change the monitoring module from the first power state to the second power state. 8. The inhaler of claim 1, wherein, when the cover is moved to expose the mouthpiece, the processor is configured to provide an indication to a user that the inhaler is primed. 9. The inhaler of claim 1, wherein the wireless transmitter comprises at least one of a Bluetooth Low Energy (BLE) integrated circuit or a BLE system on chip (SoC). 10. The inhaler of claim 1, further comprising a light emitting diode (LED), wherein the processor is configured to activate the LED upon the monitoring module changing from the first power state to the second power state. 11. The inhaler of claim 1, wherein the sensor is positioned distal to the mouthpiece. 12. The inhaler of claim 1, wherein the sensor is configured to measure a pressure within the monitoring module during an inhalation through a flow channel of the mouthpiece, and wherein the processor is configured to determine a flow rate associated with the inhalation through the flow channel based on the measured pressure. 13. The inhaler of claim 1, wherein the mouthpiece defines at least a portion of a flow channel. 14. The inhaler of claim 13, wherein movement of the cover further causes the dose of the medicament to be made available to the flow channel. 15. The inhaler of claim 4, wherein the second power consumption is greater than the first power consumption. 16. The inhaler of claim 1, wherein the sensor comprises a switch. 17. The inhaler of claim 1, wherein the sensor is configured to generate a plurality of pressure measurements during an inhalation through a flow channel of the mouthpiece. 18. The inhaler of claim 17, wherein the processor is configured to determine a peak flow rate associated with the inhalation from one or more of the plurality of pressure measurements. 19. The inhaler of claim 17, wherein the processor is configured to determine a duration associated with the inhalation based on the plurality of pressure measurements. 20. The inhaler of claim 17, wherein the processor is configured to determine a volume associated with the inhalation by integrating a plurality of flow rates associated with the plurality of pressure measurements. 21. The inhaler of claim 1, wherein the monitoring module is configured to generate dosing information, the dosing information comprising at least one of: a time associated with an actuation of the sensor; a time associated with a successful administering of the dose of the medicament; a pressure measurement; an inhalation flow rate; a peak inhalation flow rate; an inhalation duration; or an inhaled volume. 22. The inhaler of claim 21, wherein the wireless transmitter is configured to transmit the dosing information to a user device, the user device comprising a smartphone, a tablet, a laptop, or a desktop computer. 23. A method of administering a dose of medicament from an inhaler having a bellows, a mouthpiece cover, a hopper, and a monitoring monitor comprising a sensor, a wireless transmitter, and a processor, the method comprising: compressing the bellows based on a movement of the mouthpiece cover; changing the monitoring module from a first power state to a second power state based on the compression of the bellows; and metering the dose of medicament from the hopper based on the compression of the bellows. 24. The method of claim 23, wherein the first power state is an off state or a sleep state, and the second power state is an on state. 25. The method of claim 23, wherein the first power state is associated with a first power consumption and the second power state is associated with a second power consumption that is different than the first power consumption. 26. The method of claim 23, further comprising activating a sensor within the monitoring module during the second power state. 27. The method of claim 23, further comprising moving a yoke connected to the mouthpiece cover to activate a sensor within the monitoring module, wherein the activation of the sensor causes the monitoring module to change from the first power state to the second power state. 28. The method of claim 23, further comprising sensing a pressure within a housing of the inhaler as the dose of medicament is inhaled from a mouthpiece. 29. The method of claim 23, further comprising generating a plurality of pressure measurements during an inhalation through a flow channel of a mouthpiece of the inhaler. 30. The method of claim 29, further comprising determining a peak flow rate associated with the inhalation from one or more of the plurality of pressure measurements. 31. The method of claim 29, further comprising determining a duration associated with the inhalation based on the plurality of pressure measurements. 32. The method of claim 29, further comprising determining a volume associated with the inhalation by integrating a plurality of flow rates associated with the plurality of pressure measurements. 33. The method of claim 23, further comprising generating dosing information via the monitoring module, the dosing information comprising at least one of: a time associated with an actuation of the sensor; a time associated with a successful administering of the dose of medicament; a pressure measurement; an inhalation flow rate; a peak inhalation flow rate; an inhalation duration; or an inhaled volume. 34. The method of claim 33, further comprising transmitting the dosing information to a user device, the user device comprising a smartphone, a tablet, a laptop, or a desktop computer. 35. The method of claim 23, further comprising illuminating an indicator when the mouthpiece cover is moved to expose a mouthpiece of the inhaler. 36. The method of claim 35, wherein the indicator signals that the dose of medicament is available to a flow channel of a mouthpiece.
