[0002] With medical and pharmaceutical progress, a wide variety of medicaments are available to treat an increasing number of diseases including chronic conditions. Chronic conditions may affect young and older people alike. As a result, a wider percentage of the population is subject to longterm treatment of chronic diseases. Elderly people are particularly affected by the constraints of taking multiple medicaments as on average the number of health problems increases with age. Many patients self-administer multiple medicaments in various forms (pills, tablets, lozenges, powder...) on a regular basis. A U.S study revealed that a third of older citizens regularly use at least five prescribed medications. It is cumbersome and challenging for an individual to adhere to several medical prescriptions especially when certain medicaments must be taken regularly or at specific times. It is particularly challenging for elderly people and / or the visually impaired to manage multiple medicaments. Managing multiple drugs increases the risk of underdosing or overdosing which can further complicate the health condition of a patient. As many patients have difficulty in adhering to their specific medication as scheduled, there is a need to help them improve adherence to their individual and often complex therapy regimens.

An access controller 44 may be implemented to ensure that the proximity sensor triggers the opening of the drawer in response to the detection of an authenticated / authorised user. For example, the use of an RFID or NFC enabled mobile phone brought into close proximity of the device could enable the device to open and prevent access by unauthorised persons. The user application 52 may be configured to provide such access to particular user only, whereby during set-up with the mobile phone user application the user’s phone is authenticated and provides a unique access key which the device recognises as it is brought into close proximity triggering the opening procedure or release of the device 21. The device may also be configured with a child lock arrangement operable both in the normal controlled mode of operation and the manual mode (used for example in the event of a power failure). Likewise a manual release mechanism could be incorporated that would allow access to the drawer in the event of a power failure or malfunction but prevent unnecessary access by a child.

[0036] FIG 2.1 and FIG. 5.3 exemplary illustrate a container (1) seated at its receiver or recess location 1a in the first row, which is the row nearest the front face of the drawer 27. The rows of containers 1 are arranged parallel to the x axis whereas the columns are parallel to the y axis (FIG. 2.1). The container (1) is in the form of a circular or substantially oval pod that has at least one opening to receive medicaments. The terms pod has also been used in the specification to refer to the containers.

[0037] The device 21 may comprise an information indicator based on lights that illuminates to identify one or more containers to be removed from the device (21). The light indicator may comprise a plurality of LEDs, each LED being associated with a respective container, wherein each light indicator illuminates to indicate that its associated container being a container that is to be removed from the device at the particular time that the user is accessing the device. When the patient engages with the device (21) and the drawer (27) is in the fully open position (second open configuration) the containers including the medication that is to be taken will be illuminated. The patient would typically remove the indicated container, open it, take a pill and then replace the container into its home location. The indicator light would then turn off at this container. The user would then be prompted to remove the next illuminated container and replace it repeating the previous steps for each illuminated container.

[0038] FIGs. 3.1 - 3.5 show several views of an exemplary pod 1 as an example of a container 1 according to the specification, including in an open configuration and in a closed configuration. Pod 1 has two openings defined by hinged lids 35 and 37. The first lid 35 of the pod 1 is hinged to side wall 39 of the pod 1 so that the first lid 35 opens to facilitate access to the entire interior surface of the pod. The second lid 37 is smaller than the first lid 35 and is formed as an integral part of the first lid 35. The second lid 37 is hinged to a central portion of the first lid 35 to facilitate insertion of a medicament. Compared to the second lid 37, the first lid 35 having a larger surface further facilitates removal of a medicament and cleaning the pod for instance. To improve safety, the pods may be provided with a locking mechanism such as a child-lock system.

[0039] Each pod 1 is at least partially transparent. The material and body of the pods is selected taking account also of the optical properties and to facilitate or to improve image capture of the medicaments inside the pod, and further to improve the quality or properties of the images I to allow counting and / or identification of the contents. In some implementations only the lids (35, 37) are transparent. The pod 1 of FIGs. 3 may for example have a diameter of the order of 60 millimetres and a suitable height for the device 21. The dimensions and form of the pod 1 are such that the medicaments especially pills can spread at the base of the pod 1 to facilitate counting based on an image capture. In the example arrangement of Figure 3.4 ab internal base surface 38 of the pod on which the pills rest is arranged to include an angled and / or stepped portion. Pills distributed along a slanted surface may be easier to count. In an implementation the pod may also have a staggered bottom surface like a staircase to facilitate the stacking of pills. The internal base surface 38 of the pod may further be patterned or roughened, incorporate raised or recessed features to spread the pills or to provide increased friction between the pills and surface to facilitate counting them. A graduation such as a scale may be provided on an internal wall of the containers (pods) to facilitate determination of the quantity and counting of the pills. The scale may be 14 arranged to extend partially or circumferentially around the interior to indicate levels within the container. Pod 1 may be provided with one or more markings to help the user identify the pod. For instance, a numeral may be embossed on the lid or a wall of the pod so that the patient can easily see the container number. Each container has an external base portion 38’, and the external base portion may include a coding member formed for mating with a corresponding coding member of a receiver provided within the housing for receiving a container

[0040] Ccontainers 1 in the device (21) of Figures 2 can only be accessed when the moveable support or the drawer 27 is moved to a position external to the housing. In this arrangement no top lid is provided. Referring to FIGs 2-5, the imaging device 11 is located inside the housing 130 preferably at a location proximate to the upper internal surface or ceiling of the device 21. The exemplary device of FIGs 2, 4, 5 an imaging device 41, which may be similar to device 11, located in an upper part of the device (e.g the ceiling) opposite the base of the device (21). The imaging device 41 may for example comprise a plurality of cameras or other imaging devices arrangement in a row. The imaging device 41 may also comprise an elongated imaging device that extends across the row of container. The imaging device is configured such that in use a camera / imaging device is provided located to capture images of each of the containers and their contents. The dotted line (41) in FIGs 2.1 and FIG 2.2 indicates the position of the row of imaging device which are located beneath the top surface (23’) of the device (21). The top views of FIGs 4.1 and 4.2 illustrate from above the device, the position (41) of the row of capture means. The imaging device 41 located proximal or adjacent the front face 135 of the device (21) through which the drawer (27) moves and out of the device (21).

[0041] Referring to the top views of FIG. 4.1 and FIG. 4.2, the device (21) comprises a number of imaging devices 11 corresponding to the number of columns of containers. As shown in FIGs 4.1 and 4.2, the device 21 has four imaging devices 11 and the drawer can receive four columns of pods 1. Referring to FIGs 2, 4, 5 the device 21 has three rows so that when the drawer (27) has received a pod 1 in each of the pod seat or receiver 1a-3d etc, the device (21) being loaded with twelve pods (1). Each row of pods 1 is configured to be moved into alignment with the imaging device 11 arranged transverse across the housing, as it moves in or out of the device (21). Hence each container in turn is located to directly face a respective imaging device.

[0042] Referring to FIGs 5 imaging device 11 (comprising a row of imaging devices / cameras) is located on the upper part of the device FIG. 5.1 pod 1 of the first row of containers is shown located directly facing the imaging device and located in the field of view. FIG. 5.3 shows a driver 53, being a component of a drive means 153 for moving the drawer 27 or movable support 123 in and out of the device 21. The drawer 27 may be operated by any suitable driving means such as a motor. Such driving means 153 is typically powered by a battery internal to the device and / or an electric power supply. The drawer or support may also be configured to allow manual operation in a manual operation mode of the device in the event of low battery or power failure. To improve safety, the device 21 may be provided with a locking mechanism such as a child-lock system that operates 15 also when the device is being operated in a manual mode. FIG. 5.4 shows that a lens or other optical component of a capture means 11 is arranged over the pod (1) Figure 5.4 shows a typical field of view of the imaging device 11. This relative position of the pod 1 relative to a capture means improves the image capture which further facilitates an improved processing to assess contents. The driver may also be configured as an agitator or shaker mechanism that causes the drawer to vibrate as it opens and / or closes and prior to image capture. Shaking the drawer may assist in evenly distributing / levelling the pills within the containers, this may assist in providing more improved images for the purposes of counting of contents.

[0043] As the drawer 27 moves out of the device (21) it first reaches a first intermediary or partially open position. In this position the recesses 1a-1d of the first row are aligned with the capture means 11. Effectively each pod 1 of the first row is vertically aligned with a corresponding image capture means 11. As the drawer reaches this position, it stops temporarily and the imaging device is triggered a capture of an image / images the pods aligned thereto and in the field of view. After the capture of images of the first row of containers, the drawer resumes its course of movement until it reaches a second intermediary or partially open position. In this position of the drawer, the recesses (seats) (2a, 2b, 2c, 2d) of the second row are aligned with the imaging device (11a, 11b, 11c, 11 d). Each pod 1 in the second row of receivers is aligned with a corresponding imaging (11 a, 11b, 11c, 11 d). The pods 1 of the second row are now in the field of view of the imaging device. As the drawer (27) reaches the second intermediary position, it stops temporarily and the imaging device is triggered to a capture of images of each of the pods. After the capture of images of the second row of containers (e.g pods), the drawer resumes its course until it reaches a third intermediary or partially open position of the support. The same steps as previously described occur so that after the drawer had stopped images are captured of each container and the respective contents. After the drawer has stopped in its third intermediary position, movement is resumed until it fully opens so that the device is opened in the second open configuration.

[0044] Similar steps as above occur as the drawer returns into the housing of the device 21 so that the capture means (11a, 11b, 11c, 11 d) captures images at the first, second and third intermediary / partially open positions as the drawer moves to return to the closed configuration. In the arrangement described the containers are provided in 3 rows and images are taken three times during opening and closing. If fewer or a greater number of rows were provided the number of imaging event would be adjusted accordingly.

[0045] The drive means 153 or motor position be used by the device 21 or controller 50 to trigger the capture images of a row of containers at a particular partially opened configuration. Other suitable means for example a sensor may be provided to indicate when images are to be captured. The images captured of the pods and contents during a use event are subject to the steps of the method of FIG. 11 of managing and monitoring the medication of a patient. In a particular implementation of the method of capturing images of the containers (i.e pods) and their contents, all capture means (11a, 11b, 11c, 11 d) take a picture simultaneously. Referring to the exemplary 16 device (21) of FIGs 2, 4, 5, four images are taken at the same time. In a particular implementation of the method of capturing images of the containers (i.e pods) and their contents, each capture means (11a, 11b, 11c, 11 d) is provided with a sensor to detect whether it is directly facing a container (also referred to as a pod). In the event that a capture means detects that it is not faced with a container, it may not take a picture to preserve resources powering the capture means. In this case, the system can derive that when a capture means does not capture an image, the corresponding recess opposite that capture means is not in use.

[0046] The drawer / support may be an insertable drawer / support or may comprise an insert that allows customisation to any configuration of receivers for containers 1 such as 4 by 4, 3 by 4, 3 by 3, 2 by 2 etc. The drawer could also allow different size containers to accommodate different size or quantity of medication depending on the size and frequency of the pills to be taken.

[0047] The device according to the present disclosure can be a stackable device which can be configured to include feet and indentations to allow a series of devices to be stacked one upon the other. Device 21 may be used or adapted for use in care homes and allow the management of medications for several patients on complex medication schedules. Likewise device 21 may be configured in home setting to manage two or more medication schedules for instance fora couple or as a family medication management system.

[0048] Referring to FIG.6, an exemplary device 21 in accordance with the present disclosure is represented in the form of a box having a lid 23. The device 21 of FIG. 6, is provided with an at least partially transparent upper face 25 to provide that the containers (1; 5) and their contents visible to a user when the device is closed. The lid 23 may be part of the upper face (25) of the device (21). A section of the lid may be clear or transparent to allow light penetration and to facilitate image capture of the at least one container.

[0049] Suitable imaging devices (11) include any device capable of capturing images in the form of photographs and / or video frames. The capture means is adapted to take pictures of the containers (1) and their contents at different times. The capture means may be arranged inside or outside the housing of the device to provide an appropriate image of the containers and their contents. In one example, the device may utilise a mobile phone camera to capture the images. The phone would sit into a docking cradle located on the upper section of the device. Such a system would position the mobile phone camera to accurately take an image of the pill container(s) and the contents. The application on the mobile phone would synchronise with the device hardware and software to trigger the image capture, timestamp, analyse and reconcile the container contents. Images could be captured as the drawer opens and closes through the various intermediary or fixed positions.

[0050] In examples illustrated in Figure 2, 5 and 6, the device (21) has a lid (23), which is hinged to the device. Such hinged lid is easy to operate, and it remains conveniently attached to the device (21) in either open or closed configuration. In the closed configuration (FIG 2, FIG 5.1), the lid is closed for protecting the containers (1-12). In the second open configuration (FIG 5.3), the lid is 17 fully opened for allowing user access to the containers (1-12). The capture means (11) is preferably located on the lid (23) to take a picture of the containers as the lid opens. Having the camera system housed in an enclosed environment, where light is controlled allows capture and processing of more consistent images for analysis and verification.

[0051] The device according to the present disclosure is configured to cause the capture means to take a picture of the container(s) after the device has opened and before it is in the second open configuration of FIG. 9.3. When the capture means has captured an image or series of images of the containers and their contents, it sends the image(s) to a controller (50) for assessing their contents. The controller (50) is associated with the device (21) as indicated above in relation to FIG. 1. The controller (50), which is communicatively coupled to the capture means (11) may be a processor such as a Central Processing Unit (CPU). Alternatively, the controller (50) may be part of the application (51) used to monitorand manage the medication. If the controller and the capture means are located on the same piece of electronic circuitry (on the same chip) (FIG. 1.2), they may communicate via a bus for example or any other local communication link. The controller and the capture means may be communicatively coupled by a short-range communication link such as Bluetooth or IEEE IPv6 Low PAN etc. When the controller (50) is remote from the device (21) as in FIG. 1.1, the capture means is equipped with a wireless technology such as WiFi, 4G, 5G etc. to send images to the controller (50). Data / images can be processed on a cloud.

[0052] In another example, an optical 3D laser scanning of the pills and container using a 64x64 scanning array (for example) could be used to determine medication volume. Such a scan could provide point cloud data to create a 3D model of the pills in the container. Combinations of image capture methods, 3D scanning, image / video capture would also improve counting capability.

[0053] Referring to FIG. 9, the device (21) includes various configurations including a closed configuration (FIG. 9.1), and a second open configuration (FIG. 9.3). An exemplary intermediary open configuration is illustrated in FIG. 9.2. Referring to the intermediary open configuration of FIG. 9.2 the device is not fully open for a user to retrieve or introduce a medicament. The intermediary open configuration of FIG. 9.2 is reached as the device (21) is being opened and before it reaches the second open configuration of FIG. 9.3. The skilled person would appreciate that an intermediary open configuration can be implemented in different ways depending on the type of opening allowing access to the device. Suitable openings include a door, a gap, a flap or a lid etc. These examples are not limiting, and a suitable opening may be integrated to the body of the device or it may be detachable therefrom. The device (21) is preferably configured to capture one or more images of the containers in the device when the device reaches the intermediary open configuration. The device (21) may be configured such that when it opens in the intermediary open configuration of FIG. 9.2, the capture means is triggered to take a picture of the containers. In the intermediary open configuration of FIG. 9.2, the lid (23) is partly opened. This position of the lid (23) advantageously deters a user from attempting to access the containers when the capture means (11) is about to take a picture. The device (21) can be configured such that in the intermediary open configuration a user is prevented from accessing the one or more containers.

[0054] In examples, the at least one container is transparent or semi-transparent so that the contents may be visible through the container wall. FIG. 9.2 shows that the capture means (11) may be at an angle in respect of the containers when the device (21) is in the intermediary open configuration. Depending on the optical angle of the capture means it may capture the contents of a container through the wall thereof. Thus, a container having a transparent or translucent wall is preferred to facilitate processing of the images captured.

[0055] In examples, a container is provided with a transparent cap or a translucent cap releasably secured to the container. Such a cap allows capture by the capture means of the contents of a container even when the cap covers it. The cap is preferably maintained attached to the container to protect the contents thereof and to prevent loss of the cap. The cap may be a press fit or screwcap to facilitate opening and closing the container. Other types of caps may be envisaged for releasably attaching a cap to a container.

[0056] In an example, the device (21) is configured to receive a given container at a dedicated location within the device. Several implementations are workable to allow different containers to be received at different locations. FIG. 7 is a perspective view of an exemplary device including two containers (1,10) intended to be seated at different dedicated locations within the device (21).

[0057] According to a particular implementation, each container has a different raised portion (31) at its base, and the device (21) has for each container a corresponding depressed portion (30). Thus, a depressed portion (30) for receiving a given container (1) serves as a socket into which the raised portion (31) of the container can be fitted. Accordingly, each medicament container (1) can be securely seated at its dedicated location by engaging it in the corresponding socket (30). Each container fits exclusively in its corresponding socket in the manner of a jigsaw. The container can also be removed by disengaging the raised portion from the socket. The socket (30) is preferably at the base of the device (21) so that the containers are seated horizontally as shown in FIG. 7.

[0058] In an example, the raised portion at the base of the container is a three-dimensional character and the socket is a corresponding three-dimensional character. The containers (1, 10) of FIG. 7 comprise at their base a 3D numeral (31) and the base of the device (21) comprises corresponding depressed 3D numerals (30). Referring to FIG. 7, the exemplary device (21) comprises twelve sockets (30) to receive twelve different medicament containers (1-12). A given container (1) can thus only be inserted at its dedicated location corresponding to its 3D numeral (30). The 3D character may also consist of a letter or other form of character. Each raised portion functions as key and the corresponding depressed portion functions as a key aperture. The sockets of device (21) of FIG. 7 are arranged in a grid pattern having 3 columns and 4 rows. The abovementioned features facilitate insertion of containers at their dedicated locations in the device. They facilitate organising various medicament containers. These features are advantageous for 19 elderly patients with trembling hands or neurological disorders as they assist them to place each medicament container at its dedicated location. These features provide an orderly way of storing medicaments which subsequently facilitate loading and retrieval of correct medicaments. It is critical to assist patients in storing medicaments in an ordered manner to prevent them from mistakenly taking incorrect medication or misidentifying or mixing up medication. The skilled person will appreciate that other structured arrangements are suitable to help a patient organize his / her medication in the device (21).

[0059] Referring to FIG. 8, there is provided an exemplary layout of containers within a device in which each socket has the form of a circular pad. Each socket may have a different colour and each container may have a corresponding different colour. This coloured layout helps organise different medicaments in different containers. It also aids the monitoring system in associating different medicaments with different coloured containers. This further facilitates the verification of whether a patient is using his / her medication as scheduled.

[0060] As indicated above, in an implementation, a container is provided with a mark to help the user identify the container. A numeral may be embossed on the cap of the container so that the patient can easily see the container number without turning it upside down avoiding any risk of spilling its contents. The skilled person would appreciate that examples of implementation include containers having a combination of raised portions and coloured walls. These features are desirable for elderly and / or visually impaired patients as they facilitate organising different medicament containers at different places within the device. Coloured containers are particularly more visible. Such organisation also facilitates the management and monitoring of the medication of a patient.

[0061] For this purpose, the at least one container is associated with a sensor to sense if the container is received at or removed from its dedicated location. Various types of sensors are suitable, and the sensor can be a magnetic or electrical contact for example. The sensor is communicatively coupled with the controller to signal when it detects that a given container is inserted at or removed from its dedicated location. The sensor can also help to detect if a container is misplaced within the device. Accordingly, the sensor allows monitoring of the times at which a given container is inserted or removed from its dedicated location in the device. This time could be the clock time of the processor for example. The skilled person will appreciate that such a sensor may be implemented in various ways. For instance, each container and / or each respective socket may be equipped with a sensor that signals to the controller if and when the container is not placed at its dedicated location. This information is made available to the system 51 via the device controller 50 to verify the arrangement of the medicament containers in the device. Referring to FIGs 1.1, and 1.2 the system (51) and related application 52 can be used to monitor the times at which a patient removes a medicament container accidentally or intentionally. Via the system 51, a remote operator can identify if one or more containers (1-12) are misplaced and are not sitting in their respective dedicated locations. In general, the sensorand the application (51) combined in the system can help monitor a patient medication adherence behaviour.

[0062] According to implementations, the device is prevented from closing when the sensor senses that at least one container is not positioned at its dedicated location. Advantageously, the sensor can be used to ensure that each container is correctly positioned within the container before the device is closed.

[0063] In various examples such as in FIGs 2, 3, 5 and 6, the part of the device that receives the containers is a drawer (27) that is pullable out of the device (21). Referring to FIG. 7, the arrow (33) shows a direction in which the drawer is to be extended or pulled out of the device (21). The drawer (27) has a base onto which the containers are positioned at their respective dedicated locations. Accordingly, as shown in FIG. 7 the base of the drawer comprises 3D sockets for receiving the 3D raised portions of the respective containers.

[0064] In various examples, the drawer (27) is prevented from closing unless each container is sitting at its dedicated location. This helps to ensure that the arrangement of the containers in the device matches a pre-configured arrangement.

[0065] In an implementation, the image capture is a video frame instead of a photographic image. Of course, the skilled person would appreciate that the invention works through the capture of a combination of video frames and photographic images.

[0066] FIG. 10 shows various configurations of the device at five different times to illustrate a sequence of positions as a patient opens the device and then closes it. Any one of the five positions of FIG. 10 corresponds to a configuration presented with reference to FIG. 9.

[0067] The device (21) of FIGs 5 and 6 comprises a lid (21) and a drawer (27) as well as a capture means exemplary located on an internal portion of the lid (23). The skilled person would appreciate that the capture means may advantageously be located on the drawer (27). The positions of FIG. 10 include a closed configuration (FIG. 10.1 and FIG. 10.5) and three open configurations (FIGs. 10.2, 10.3 and 10.4).

[0068] At a first-time in FIG. 10, the device (21) is shown in the closed configuration whereby the lid (23) is closed so that the containers are inaccessible by a user. In the closed configuration, the device is fully closed such that the drawer (27) is not removable from within the housing of the device (21).

[0069] In an exemplary implementation, the device may be in a hibernation mode when in the closed configuration. The device may transition from the hibernation mode to an “Active Mode” when the user manually interacts with the device (21). For example, pushing a button on the device would power the device up from hibernation activating the capture means and possibly illuminating internal LED lights. The “Active Mode” can also be entered when a prompt is received through the user application indicating a time to take the medication. In an example, the device may be powered on or may enter its “Active Mode” when a proximity sensor provided on the device detects the nearby presence of a user. For example, an LED light or other indicator may indicate that it is 21 time to take medication. The patient then approaches the device and waves his / her hand over the LED light or sensor for instance. This triggers opening of the drawer and an image capture sequence described earlier. Once the medication has been taken, and all the containers are returned to their dedicated positions, and the LEDs associated with the containers are extinguished, the patient may for instance hover his / her hand over the proximity sensor to initiate closing the device.

[0070] At a second time in FIG. 10, the device (21) is shown in an intermediary open configuration whereby the lid has reached an intermediary open position after it has opened. In an example, the device is prevented from opening in the second open configuration of FIG. 10.3 unless the capture means captures at least one image of the containers and their contents. In an implementation, the lid (23) may be made to stop or to lock into place when it has reached the intermediary open position of FIG. 10.2. The position of the lid depicted in FIG. 10.2 activates the capture means (e.g internal camera). This position triggers the capture means to take a picture (possibly with timestamp) of the contents of each of the containers. In an implementation, the lid is momentarily stopped / locked in the intermediary open position of FIG. 10.2 for a duration of time during which the capture means takes at least one picture. The picture taken at this time provides an image of the containers and of their contents during the opening process prior to the lid being fully opened. After the image capture, the lid is unlocked to reach the second open configuration of FIG. 10.3 in which the container is accessible to retrieve / load medicaments. In an implementation, the lid remains locked in the intermediary open position for image capture until further user action on the lid.

[0071] At a third time in FIG. 10.3, the device (21) is opened in a second open configuration when the lid is fully opened. In an example, the drawer (27) is enabled to extend out of the device (21) in the second open configuration, when the lid is fully opened. In a particular example, the drawer (27) extends out automatically when the lid is fully opened. At the third time the drawer is shown in FIG. 10.3 in the extended position when the lid is fully opened. In an example of second open configuration, the user is enabled to access the containers when the drawer is positioned within the housing of the device. This feature eliminates the need to pull the drawer from the device to access the containers.

[0072] At a Fourth time in FIG. 10.4, the device (21) is opened again in the intermediary open position where the lid has reached the position of FIG. 9.2. In this intermediary open position, the lid locks into place and triggers the capture means to capture the image of the containers. As described above, in this intermediary open position, the lid may be momentarily stopped / locked or it may remained locked until further user action on the lid. The stopping / locking of the lid prevents the lid from moving during image capture and provides a stable image of the containers and of their contents at the time of the capture. Referring to the configurations of FIGs 10.2, 10.4 (FIG 9.2), in second and fourth times on FIG. 10 the drawer (27) is returned to the housing. The drawer is preferably prevented from being pulled out of the device (21) unless the capture means captures 22 an image in the intermediary open configuration of FIG 10.4. This mechanism can be achieved by preventing the drawer (27) to be pulled out unless the device (21) has reached the second open configuration of FIG 10.3. In this example, the lid must be fully opened in the second open configuration for the drawer to be allowed to extend. In another implementation the drawer is allowed to extend when the device is in the intermediary configuration of FIGs. 9.2, 10.2 and the lid is not fully opened. The position at Fourth time of FIG. 10.4 illustrates for instance the configuration of the device (21) after an event of retrieval of medicament by the patient. The device preferably prevents movement of the lid when the drawer is at least partly pulled out of the housing. This ensures that the drawer is returned within the housing before the device reaches the intermediary open configuration (FIG. 10.4) so that an image captures all the containers.

[0073] The mechanism described in FIG. 10 provides an image of the containers and of their contents as the device opens before user access. The capture means advantageously takes an image before closure of the device. Accordingly, images taken during each opening and each subsequent closure can be correlated to derive a quantity of medicament retrieved by a user. This data can be used to monitor the use of medicaments by a patient over time and to assess compliance with a predefined prescription schedule. For instance, the controller (50) associated with the device (21) receives from the capture means (11) images captured at different times. Based on these images, the controller (50) assesses at least a quantity of medicament in the at least one container at the different times so as to manage and monitorthe medication of the patient. The capture means (11) may timestamp each image at the time of its capture to facilitate the processing by the controller (50) of different images taken at different times.

[0074] At a Fifth time of FIG. 10 (FIG. 10.5), the device (21) is in the closed configuration where the lid (23) is fully closed.

[0075] The capture means (11) may send an image captured to the controller (50) at any time after its capture. The capture means may send an image to the controller just after the image capture while the device is in the intermediary open configuration of FIGs. 10.2 and 10.4. Alternatively, images captured while the device is opened may be sent to the controller when the device is in the closed configuration (FIGs. 10.1, 10.5).

[0076] After a predetermined period of time in the closed configuration, the device may enter the hibernation mode to save power resources.

[0077] FIG. 11 illustrates steps of a method of managing and monitoring the medication of a patient according to an implementation of the present disclosure. FIG. 11 illustrates the controller (50) being communicatively coupled with the capture means (11) of the device (21). The application (51) is communicatively coupled with the controller (50). The application (51) may be user-friendly to conveniently monitor the patient behaviour and to ensure that the patient is taking his / her medication as prescribed. The application (51) would typically be made available to a carer or an hospital staff member and / or the patient or customer care team.

[0078] A patient prescription schedule can be provided to the controller (50) via the application (51) through a configuration step such as step (702).

[0079] At step 703, the controller may also receive a pre-defined arrangement indicating a predefined position for each container in the device (21). For instance, the controller (50) may receive a layout such as that of FIG. 8 comprising a position of each container together with the medicament(s) contained therein. The patient prescription schedule (7031) and the pre-defined arrangement (7032) may be provided at step 703 by filling a patient profile through the application (51).

[0080] In an example, a configuration of the device (21) comprises a “Load Mode”, in which the user is allowed to load the medication in different containers. The user application (51) can advantageously assist a user to assign the drugs to their corresponding containers. After the initial loading, the device (21) takes a picture of the loaded containers at time t0 and sends it to the controller at step 701. The controller (50) receives through the image sent at step (701) an “predefined arrangement” (7032) of the patient’s medicaments in the device (21). The pre-defined arrangement indicating a pre-defined position for each container, can be used against images taken overtime to monitor the current positions of the containers. The configuration of FIG. 11 is exemplary and other methods may be employed to provide the controller with the prescription schedule (7031) and pre-defined arrangement (7032).

[0081] The Table 1 below shows an exemplary pre-defined arrangement (7032) of containers as initially loaded with medicaments in the device. The first column represents an Identity (ID) of the container, which can be for instance a color, a number or a label that uniquely identifies the container in the device. The second column represents the position of each container in the device (21), which is the dedicated position described earlier. The third column describes the name or the type of medicament prescribed to the patient. The fourth column represents an initial quantity of medicament for each container. Referring to the layout of FIG. 8 a table of a pre-defined arrangement (7032) indicates that the Yellow, Green, and Red containers are located at respective positions 1,2, 3.

[0082] The ID, position, medicament and initial quantity of Table 1 may have been recognized by the controller (50) from an image sent through configuration step 701. Alternatively, or in combination with step 701, at least some of these items may have been entered manually through the application at configuration step 702. Container ID (e.g color Number / label) Initial position of container in Box medicament Initial Quantity Yellow 1 Pills for chronic condition Q1 Green 2 Pill for heart condition Q2 Red 3 Tablet for lungs Q3 Table 1: Pre-defined arrangement

[0083] As indicated above, the controller (50) may have received a pre-defined arrangement (7032), and a prescription schedule (7031) through configuration steps 701, 702. The following Table 2 illustrates an example of a prescription schedule (7031) gathering information of medical prescriptions for a patient. medicaments Time slots Quantity Pills for chronic condition Day 1 Morning qim Afternoon qia Evening qie Pill for heart condition Day 2 Morning C|2m Afternoon q2a Evening q2e Tablet for lungs Day 3 Morning C|3m Afternoon q3a Evening q3e Table 2: prescription schedu e

[0084] Referring to FIG. 11 at step 711, the capture means (11) sends the image taken at time to the controller (50) for the controller to process the image.

[0085] At a later time + At, when the patient closes the box device, the capture means takes a picture of the containers and their respective contents. This capture occurs for example when the device reaches again the intermediary open configuration (FIG. 9.2) before closure (FIG. 9.1).

[0086] At step 712, the capture means (11) sends the image taken at time + At, to the controller (50) for processing the image.

[0087] At step 713, the controller (50) processes the images taken earlier to assess the contents of the containers at the respective times and + At. At step 713, the controller associates each container with its identified contents at respective times and + At- The processing of step 713 is intended to verify that the contents of the containers at a given time is in line with the expected contents as recommended by a prescription schedule.

[0088] At step 713, when processing an image taken at or at + At, the controller (50) may identify a label of each container and associate its contents with the respective label. Labelling the containers such that the labels are captured on an image facilitates associating each container with its respective contents. This will facilitate assessing whether the contents of a device (21) at a given time is in accordance with a prescription schedule (7031). Alternatively, or in combination with the label, an exemplary method comprises identifying the color of each container in the image together with its respective contents. The controller (50) is then capable to easily associate at step 713 a color with the contents of the container having this color. This facilitates verifying at step 714 a captured arrangement against a pre-defined arrangement (7032) of coloured medicaments containers.

[0089] At step 713 the controller (50) can recognize in a given container at least a quantity of a medicament. At step 713 the controller may also determine based on the images captured a position of one or more containers in the device at each of times and + At. At step 713 the controller may determine a medicament type and the quantity thereof in each container as well as an identity (e.g colour / number / label) of each container.

[0090] The controller may use for instance Artificial Intelligence or Al techniques and machine learning algorithms to interpret images and recognize contents at step 713. [0091 ] The association of step 713 can be carried out for one or more containers after each image capture or after a number of image captures. The association results can be stored in a variety of data structures including but not limited to linked list and tables. The following table exemplary illustrates the association between a given container and its contents at different times and + At. Of course, the skilled person would understand that a table of association may include all the containers and their respective contents at different times. For simplicity this is not represented in Table 3. Time of image capture Container ID (e.g color Number / label) Current position of container in Box medicament Current Quantity ti Yellow 1 Pills for chronic condition QT + At Yellow 1 Pills for chronic condition Q1” Table 3: Container captured at differen times

[0092] At step 713, the controller may also determine based on the images obtained at times tr and + At, if a container received or dispensed a medicament as well as the quantity received or dispensed. For instance, referring to Table 3, the controller identified at step 713 that container “yellow” including “Pills for chronic condition" contains quantity Q1’ at time and quantity Q1” at time + At- The controller (50) computes the difference between Q1” and Q1’ to determine a quantity received at or retrieved from the container between the times and + At-

[0093] At step 714, the controller can verify the position of each container based on the association established at step 713. For instance, the controller verifies that each container is located at a position indicated by the received pre-defined arrangement (7032). The controller may verify that the position of container “yellow” at time in Table 3 is identical to its initial position as defined in the pre-defined arrangement of Table 1. Instead of the ID (e.g colour / number / label) or in combination with the ID, the controller may use the recognized medicament type to perform the verification. For instance, via Table 3, the controller can verify that the “Pills for chronic condition" are located at position “1" in the box device as provided in the pre-defined arrangement of Table 1. The controller (50) can thus verify that an arrangement of all medicaments in the device (21) corresponds to a predefined arrangement (7032). This verification advantageously allows monitoring the position of a container over time. In particular, it allows identifying if a current position of a container is different from its initial position as provided in the configuration steps (701, 702). This method can help inform a carer about whether a patient has inadvertently misplaced a container to a position different than its dedicated position in the device.

[0094] At step 714, the controller also verifies that the quantity recognized in each container at times t and t + At corresponds to a quantity expected by the prescription schedule. For instance, referring to Table 3, the controller identified at step 713 that container “yellow / ’ including “Pills for chronic condition" contains quantity Q1’ at time and quantity Q1” at time + At- The controller then checks this information against the prescription schedule information provided by Table 2. For instance, the controller checks if the time + At falls in any of the time slots of the prescription schedule such as “Day 1 morning”. If yes, the controller (50) checks if current quantity of medicament Q1” at + At less Q1’ at in container “yellow” corresponds to q1m as prescribed by Table 2. If it is, this information will provide a level of confidence to a monitoring person that the patient has taken his / her medicine as scheduled. Otherwise, the monitoring person would be informed of the discrepancy between the actual container contents and the expected ones. Through step 714 the controller assesses whether the utilization of the medicament containers is compliant with a prescription schedule received at step 703.

[0095] Referring to FIG. 11, in an implementation, the controller (50) reports to the application (51) the results of the processing (713) and verification steps (714). The controller (50) may send a notification (715) to alert that the controller has verified an arrangement of at least one medicament container in the device. The notification message (715) can be a SMS message, email, SIP Notification or other form of message destinated to a patient and / or a carer.

[0096] The application (51) and the controller (50) may communicate via a network if they are separate or via an interface such as an API if they are co-located. The information sent from the controller to the application is intended to be used to manage and monitor the medication of the patient. The results of the processing step (713) and / or verification step (714) are displayed via the application at step (716) to visualize a patient behavior. Accordingly, the information gathered from consecutive images captured can be displayed in various suitable forms through the application (51).

[0097] In various implementations, the controller (50) alerts the application (51) when it detects specific events. The controller (50) may send the application (51) a notification when the quantity of medicament dispensed at different times is non-compliant with the prescription schedule.

[0098] Referring to step (714) of Fig 7, the controller (50) may compute a difference between a quantity recognized in a container at time + At and a quantity in the same container at time Thus, the controller derives the quantity of the medicament dispensed by the container and compares this quantity to the quantity expected to be consumed as set by the prescription 27 schedule. If the quantity of medicament dispensed during interval [tx , + At] differs from the quantity prescribed to be consumed in a slot covering this time interval the controller alerts the application. The controller may alert the application through a message such as a notification (715) presented above.

[0099] The alert or the notification (715) may include an instruction to refill a given container, when the quantity of medicament in that container falls below a pre-determined threshold. The predetermined threshold is a parameter that is typically entered during a configuration step such as configuration step (702). Each medicament container may be associated with a different predetermined threshold. Pharmacy collection and / or appointment reminders may also be provided through an alert implemented by the notification (715).

[00100] The steps described earlier can be repeated so that at later times tn and tn+M when a user opens and closes the device (21) images are sent to the controller (steps 7n1 and 7n2). Subsequently, processing step (7n3) and verification step (7n4) similar to the earlier steps (713) and (714) are carried out. At step (7n5), the controller sends results to the application (51) for a user to monitor a patient medication adherence behaviour through a Graphical Interface (7n6). Advantageously, the results of the processing, assessment and verification steps are available visually in near real time as a patient opens and closes the device. Making results available in this manner can advantageously inform a carer in near real time about when different medicaments are retrieved as a patient accesses the device (21). According to alternatives and arrangements envisaged. One or more of Image processing and data processing and control may be performed locally or remotely. It will be appreciated that while processing and data management described may have been in the specification as local or remote for the purposes of illustrating an exemplary arrangement - such processing and data analysis and other control can be implemented locally or remotely.

[00101] In various implementations, the controller 50 is configured to record successive images received over time. In an implementation, instead of processing each image as it obtains it, as shown in Figure 7, the controller can differ this processing to process a series of recorded images. In this implementation, the controller (50) carries out image processing and verification steps after a period of time or after a number of times the device (21) opened and closed. The controller can perform processing and verification steps once fora batch of recorded images. Over a long period of time, this implementation reduces significantly the number of processing and verification steps. However, each processing step and each verification step is computationally more expensive because each requires the processing of a greater number of images and data. In such an implementation, the results of the processing and verification steps are not available in near real time as a patient opens and closes the device (21). However, when the processing and verification steps are carried out, the application (51) is informed about whether the contents over a period of time follows a prescription schedule.

[00102] Local / on unit controller processing where the unit verifies and interprets the images will cut down on processing time significantly. Since images will not have to be uploaded to the cloud, on chip counting of pills directly takes place.

[00103] In an implementation, the controller (50) is part of the application (51) so that results of the image processing and verification steps are directly available to the application. This implementation provides the benefit of a real time availability of the results on an application graphical interface as they are being obtained by the controller.

[00104] The skilled person would appreciate that features of the device (21) presented in FIGs 2, 4, 5 can be combined with features of the device (21) presented in FIGs 6, 7, 9 and 10. For instance the lid (23) of device (21) of FIGs 9, 10 may be provided with a line of capture means as described with reference to FIGs 2, 4, 5. The pods described in FIG 3 may be used in the device of FIGs 6, 7, 9 and 10. The method steps of managing and monitoring medication of a patient presented in FIG. 11 is applicable to any device (21) presented above.

[00105] The systems and methods of the described examples may be implemented in a computer program product such as a physical, non-transitory computer readable medium having computer readable instructions. The medium may be provided in various forms, including one or more diskettes, compact disks, tapes, chips, magnetic and electronic storage media, volatile memory, non-volatile memory and the like. Non-transitory computer-readable media may include all computer-readable media, with the exception being a transitory, propagating signal. The term non-transitory is not intended to exclude computer readable media such as primary memory, volatile memory, RAM and so on, where the data stored thereon may only be temporarily stored. The computer useable instructions may also be in various forms, including compiled and uncompiled code.

[00106] Although numerous details are provided through the above examples, other examples may be practiced without these details. The description is not to be considered as limiting the scope of the disclosure.
