Abstract

Some embodiments are directed to a system for monitoring an inhaler that includes a volume of medicament for dispensation to an individual. The system includes a transmitter, disposed at the inhaler, for wirelessly transmitting data relating to the aspect of the inhaler. A monitor, which is remote from the transmitter and the inhaler, includes a receiver for receiving the data wirelessly transmitted from the transmitter, the data relating to the aspect of the inhaler including positional data relating to a relative position of the inhaler relative to the monitor and in particular a distance separating the inhaler and the monitor. The monitor also includes a processor for determining whether the distance separating the inhaler and the monitor exceeds a predetermined distance, the processor causing actuation of a notification device upon determining that the distance separating the inhaler and the monitor exceeds the predetermined distance.

Claims

1. A system for monitoring an inhaler that includes a volume of medicament for dispensation to an individual, the system comprising:

an inhaler comprising a housing for receiving a medicament storage canister and comprising a trigger, and a transmitter for wirelessly transmitting data comprising a location of the inhaler;

a wearable monitor which is configured to be worn on the individual'"'"'s wrist and which comprises;

a receiver for receiving the data wirelessly transmitted from the transmitter,

an inertia sensor comprising a gyroscope and an accelerometer configured to track orientation of the inhaler during actuation of the trigger,

a surface electromyogram (sEMG) sensor configured to collect muscle data from the individual'"'"'s wrist corresponding to the force and duration of actuation of the trigger,

a microprocessor configured to

compare an orientation of the inhaler while dispensing the volume of medicament with a predefined dispensing orientation,

compare an applied trigger pressure and duration with a pre-defined motor unit action potential data range, including a predefined trigger pressure and trigger duration, wherein the predefined trigger pressure and trigger duration are obtained from the muscle data, and

determine whether a distance separating the inhaler and the wearable monitor exceeds a predetermined distance, and

a vibration motor and light which are configured to notify the individual of (i) an erroneous inhaler orientation, (ii) an erroneous actuation of the trigger, and (iii) excessive separation distance between the inhaler and the monitor, thereby permitting the individual to adjust use or location of the inhaler.

2. A system for tracking inhaler usage techniques comprising:

an inhaler comprising a housing for receiving a medicament storage canister and comprising a trigger, a positioning mechanism providing locational data, and a transmitter for wirelessly transmitting data comprising a location of the inhaler; and

a wearable monitor configured to be worn on an individual'"'"'s wrist and which comprises;

a receiver for receiving the data wirelessly transmitted from the transmitter,

an inertia sensor comprising a gyroscope and an accelerometer configured to track orientation of the inhaler during actuation of the trigger,

a surface electromyogram (sEMG) sensor configured to collect muscle data from the individual'"'"'s wrist corresponding to the force and duration of actuation of the trigger, and

a microprocessor configured to

compare an orientation of the inhaler while dispensing medicament with a predefined dispensing orientation,

compare an applied trigger pressure and duration obtained from the muscle data with a predefined trigger pressure and trigger duration,

determine whether a distance separating the inhaler and the wearable monitor exceeds a predetermined distance, and

notify the individual of (i) an erroneous inhaler orientation, (ii) an erroneous actuation of the trigger, and (iii) excessive separation distance between the inhaler and the monitor, thereby permitting the individual to adjust use or location of the inhaler.

3. The system of claim 2, wherein the monitor further comprises a light and a vibration motor configured to provide said notifying.
