DETAILED DESCRIPTION
[0031] The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention.
[0032] The monitoring device comprises a main module 10.
[0033] The main module 10 can be attached to the inhaler directly (e.g. by snap fitting), via simple attachment means (e.g. via double-sided adhesive tape), or via a holder module 30, 40, 50, 60 that is attachable to the main module 10 and dedicated for the particular type of inhaler.
[0034] The main module 10, as shown in FIG. 1, has a body 11 for accommodating operating modules 21-24 therein, as will be explained further below. The body 11 preferably has a flat cylindrical shape, as this is optimal for accommodating necessary modules and can be easily attached to most types of inhalers, though other shapes of the body are possible, such as cubical, ball-shaped etc.
[0035] The body 11 has attachment means 12 for attaching a holder module 30-60 to the body 11. For example, the main module attachment means 12 may have a form of a plurality of cylindrical holes 13 and a plurality of slots 14, wherein the holes 13 are arranged along a circumference of a top flat surface of the cylindrical body 11 and the slots 14 are arranged in the middle of that surface, arranged in perpendicular to each other, as shown in the embodiment of FIG. 1. However, other types of attachment means 12 are possible as well, such as a plurality of protrusions, or magnets or hooks. The holder module 30-60, as will be explained further below, comprises holder module attachment means 32-62 compatible with the main module attachment means 12, so that the modules can be coupled by a form fit connection, magnetic connection, snap fit connection etc. or a combination of different types of connections.
[0036] The body 11 further comprises a pivotable arm 15 which can pivot along a hinge 16, for example by 90 degrees (as shown in FIG. 1) or another angle such as 180 degrees. The pivotable arm 15 comprises a sensor 17 mounted therein.
[0037] The sensor 17 can be of a variety of types. For example, the sensor 17 can be a microphone, a pressure sensor, a pressing force sensor (such as a mechanic or electronic button, such as a press-button or a switch), magnetic field sensor (such as a Hall sensor), a light sensor, a temperature sensor, an image registering module, a humidity sensor, an accelerometer, a gyroscope, a magnetometer, a volatile particles (VOC) sensor, an alcohol sensor, a capacitive sensor (such as a touch sensor), a proximity ultrasound or infrared sensor, a resistive pressing force sensor, a tensometer, a piezoelectric sensor, or a proximity sensor, or a set of two or more of the aforementioned sensors.
[0038] At least one of the sensors 17, 22 is configured to detect use and/or non-use of the inhaler.
[0039] Preferably, the sensor 17 is a proximity sensor 17 configured to detect whether there is an object proximal thereto, i.e., within a specific detection distance, such as 1 mm, 5 mm or 10 mm. The detection distance of the proximity sensor 17 can be adjustable.
[0040] The operating modules accommodated within the main module 10 may include, as shown in FIG. 2, a microcontroller 21 to which at least one sensor 17, 22 is connected. The microcontroller 21 is configured to receive measurements made by the at least one sensor 17, 22, optionally process these measurements (for example, by collecting measurements over a specific time period, pre-processing measurements to filter out noise etc.) and provide an output to a data interface 23. The data interface 23 can be a wireless communication module using a common standard to connect to a user device, such as a computer, a smartphone, or to a cloud server. For example, the wireless data interface 23 can operate according to one of known standards such as WiFi, Bluetooth etc. Alternatively, a wired data interface 23 can be used. The data interface 23 can be a separate module or a module integrated into the microcontroller 21. A signaling module 24, such as a sound generator, a buzzer, a light (such as a LED diode), a display is configured to provide information to the user. The modules 21-24 are powered from a battery 25. The battery 25 can be replaceable or can be charged via a dedicated charging port.
[0041] FIGS. 3A-3C present the monitoring device with a first embodiment of the holder module 30, wherein FIG. 3A shows the modules 10, 30 before assembly, FIG. 3B shows the modules 10, 30 assembled to form the device and FIG. 3C shows the device coupled to an inhaler. The holder module 30 has a body 31 comprising holder module attachment means 32 in a form of protrusions 33, 34 compatible with the holes 13 and slots 14 of the main module attachment means 12. The body 31 has formed therein an inhaler coupler 35 in a form of a protruded ring of an internal diameter corresponding to an external diameter of a canister 3A of a pMDI inhaler 3. Thereby, the device can be coupled to the pMDI inhaler 3 by mounting it on the canister 3A, with the pivotable arm 15 set to a position such that the proximity sensor 17 can detect two states: a first non-use state, wherein the proximity sensor 17 faces the canister 3A (as shown in FIG. 3C), and a second use state wherein the canister 3A is pressed downwards within the body 3B of the inhaler, such that the proximity sensor 17 faces the inhaler body 3B, which can be detected as a closer distance by the proximity sensor 17. In such a case, the proximity sensor 17 can have its detection distance set to a value shorter than a distance d1 between the proximity sensor 17 and the canister 3A, so that when the canister 3A is pressed, the proximity sensor 17 can detect the presence of the inhaler body 3B which will appear within the detection distance d1. Therefore, use of the inhaler is detected by detecting presence of inhaler body 3B within the detection distance d1.
[0042] FIGS. 4A-4C present the monitoring device with a second embodiment of the holder module 40. The holder module 40 has a body 41 comprising holder module attachment means 42 in a form of protrusions 43, 44 compatible with the holes 13 and slots 14 of the main module attachment means 12. The body 41 has formed therein an inhaler coupler 45 in a form of a protruded ring having internal diameter equal to an external diameter of a cap 4A of a Turbohaler inhaler 4. Thereby, the device can be coupled to the Turbohaler inhaler 4 by mounting it on the cap 4A, with the pivotable arm 15 set to a position such that the proximity sensor 17 can detect two states: a first non-use state, wherein the proximity sensor 17 faces the body 4B (as shown in FIG. 4C) of the inhaler, and a second use state wherein the cap 4A is removed and the proximity sensor 17 does not detect the proximity of the inhaler body 4B. In such a case, the proximity sensor 17 can have its detection distance set to a value approximate to a distance d2 between the proximity sensor 17 and the inhaler body 4B, so that when the device is removed from the inhaler 4 along with the cap 4A, the proximity sensor 17 can stop detecting the presence of the inhaler body 4B which no longer appears within the detection distance d2. Therefore, use of the inhaler is detected by detecting non-presence of inhaler body 4B within the detection distance d2.
[0043] FIGS. 5A-5C present the monitoring device with a third embodiment of the holder module 50. The holder module 50 has a body 51 comprising holder module attachment means 52 in a form of protrusions 53, 54 compatible with the holes 13 and slots 14 of the main module attachment means 12. The body 51 has formed therein an inhaler coupler 55 in a form of a clamp with elastic arms configured to attach the holder module 50 to a body of a Ellipta inhaler 5. Thereby, the device can be coupled to the Ellipta inhaler 5 by mounting it on the inhaler body 5B, with the pivotable arm 15 set to a position such that the proximity sensor 17 is present in an area to which a pivotable cap 5A of the inhaler 5 is moved during use of the inhaler. Therefore, the proximity sensor 17 can detect two states: a first non-use state, wherein the proximity sensor 17 faces the body 5B (as shown in FIG. 5C) of the inhaler, and a second use state wherein the cap 5A is folded away towards the area within the line of detection of the proximity sensor 17. In such a case, the proximity sensor 17 can have its detection distance set to a value closer than a distance between the proximity sensor 17 and the inhaler body 5B, so that when the cap 5A is folded away, the proximity sensor can detect its presence. Therefore, use of the inhaler is detected by detecting presence of the cap 5A within the detection distance.
[0044] FIGS. 6A-6C present the monitoring device with a third embodiment of the holder module 60. The holder module 60 has a body 61 comprising holder module attachment means 62 in a form of protrusions 63, 64 compatible with the holes 13 and slots 14 of the main module attachment means 12. The body 61 has formed therein an inhaler coupler 65 in a form of a clamp with elastic arms configured to attach the holder module 60 to a body of a Diskus inhaler 6. Thereby, the device can be coupled to the Diskus inhaler 6 by mounting it on the inhaler body 6B, with the pivotable arm 15 set to a position such that the proximity sensor 17 is present in an area within which a rotatable portion 6A of the inhaler 6 operates. Therefore, the proximity sensor 17 can detect two states: a first non-use state, wherein the proximity sensor 17 faces one fragment of the rotatable portion 6A (as shown in FIG. 6C) of the inhaler, and a second use state wherein the rotatable portion 6A is rotated to a position wherein it has a different shape and the proximity sensor 17 can detect a change of distance that it perceives.
[0045] As shown in FIGS. 3A-3C to 6A-6C, all the holder module attachment means 32, 42, 52, 62 are compatible with the main module attachment means 12 in so far as they can be coupled together, but the configuration of protrusions 33-34 to 63-64 is different. Thereby, the main module attachment means 12 may comprise sensors for detecting which portion of the main module attachment means 12 is coupled with the holder module attachment means 62, thereby detecting the type of the holder module 30-60 to which the main module 10 is attached, and thereby the type of inhaler to be monitored. This information can be next used to configure the microcontroller 21 operation, for example to determine which type of sensors 22 shall be used to monitor the inhaler and to configure the detection distance of the proximity sensor 17.
[0046] The microcontroller 21 allows to monitor the inhalation process based on data from measurement sensors 17, 22. In a simple embodiment, the device may be configured to simply measure when the device was used by means of one of the sensors 17, 22, such as by means of detecting change of state of the proximity sensor 17. For example, it can register a date and time of use (in particular, the start and end of use). However, if more sensors 22 are installed, various other parameters can be measured, depending on the type of sensor 22 used. For example, the sensors 22 may include a microphone, a pressure sensor, a light sensor, a temperature sensor, a camera, a gas sensor, a volatile components (VOC) sensor, an alcohol sensor, a magnetic force sensor such as a Hall sensor, a humidity sensor, an accelerometer, a gyroscope, a magnetometer, a capacitive sensor such as a touch sensor, an ultrasound proximity sensor, an infrared proximity sensor, a resistive pressure sensor, a tensometer, a piezoelectric sensor.
[0047] Moreover, the main module may comprise further components, such as a video recorder, an NFC module, an RFID module, a press sensor such as a mechanical and/or electric button or a switch.
[0048] While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made. Therefore, the claimed invention as recited in the claims that follow is not limited to the embodiments described herein.
