Adherence-tracking and monitoring device for metered-dose inhaler

An adherence-monitoring and tracking device for capturing usage of a metered dose inhaler (MDI), the device comprising:

• an enclosure for accommodating the MDI, wherein the enclosure comprises:
• a hollow cylindrical-portion configured to receive the MDI;
• a foldable-flap integral to the cylindrical-portion from a first end configured to cover a top portion of the MDI;
• and
• a plurality of magnetic-contacts configured to latch a second end of the flap to the cylindrical-portion;
• and
• an electro-mechanical system forming a part of the enclosure, and configured to capture an operation of the MDI and electronically render data thereof, the electro-mechanical system comprising:
• a microcontroller;
• at least one transducer configured to capture one or more parameters pertaining to the operation of the MDI by a user, wherein the microcontroller is configured to process said captured one or more parameters at a periodic sampling interval of less than 10 milliseconds, wherein the microcontroller is configured to process the captured one or more parameters received from said at least one transducer during the operation of the MDI to ascertain:
• a) a number of steps undertaken during an inhalation maneuver by the user;
• b) shaking of the MDI before usage;
• c) occurrence of exhalation before inhalation;
• d) inhalation for a certain duration before and after generation of spray;
• and
• e) restoration of an actuator of the MDI, wherein the microcontroller is further configured to process the captured one or more parameters received from said one or more transducers to derive an inhalation-profile of the user;
• and to identify a triggering flow-rate based on the inhalation-profile, and wherein the microcontroller is further configured to determine at least one error of the operation of the MDI due to execution of one or more parameters of parameters a) to f), and wherein the at least one error of the operation is triggered in response to referring said inhalation-profile.

An adherence-monitoring and tracking device for capturing usage of a metered dose inhaler (MDI), the device comprising:

• a housing configured to accommodate the MDI defined by an assembly of a canister and a mouth-piece, wherein the housing comprises:
• an elongated hollow-block open at a bottom of the housing configured to accommodate a canister of the MDI;
• and
• a cover hinged at the bottom of the hollow-block, wherein said hinged cover is rotatable to act as a removable-lid at the bottom of the hollow-block and thereby selectively cover a mouthpiece linked to the canister accommodated in the hollow-block;
• and
• an electro-mechanical system supported within the housing, and configured to capture an operation of the MDI and electronically-render data associated thereto, the electro-mechanical system comprising:
• a microcontroller;
• at least one transducer configured to capture one or more parameters pertaining to the operation of the MDI by the user, wherein the microcontroller is configured to process said captured one or more parameters at a periodic sampling interval of less than 10 milliseconds, wherein the microcontroller is configured to process the captured one or more parameters received from said at least one transducer during the operation of the MDI to ascertain:
• a) a number of steps undertaken during an inhalation maneuver by the user;
• b) shaking of the MDI before usage;
• c) dislodgement of an actuator cap from the MDI;
• d) occurrence of exhalation before inhalation;
• e) inhalation for a certain duration before and after generation of spray;
• and
• f) restoration of an actuator of the MDI, wherein the microcontroller is further configured to process the captured one or more parameters received from said one or more transducers to derive an inhalation-profile of the user;
• and to identify a triggering flow-rate based on the inhalation-profile, and wherein the microcontroller is further configured to determine at least one error of the operation of the MDI due to execution of one or more parameters of parameters a) to f), and wherein the at least one error of the operation is triggered in response to referring said inhalation-profile.
