The technical field relates to systems and methods for filling pill and medicine packaging. In particular, the present application relates to a tray system for filling blistered pack-type pill packaging with pills.
Blister packaging, often referred as blistered packs or blister cards, are commonly used in the pharmaceutical field for protecting and distributing pills or any type of medicine provided in single units, such as tablets or capsules. A blister pack usually comprises containers or chambers, in which pills are deposited. The containers are then sealed with material such as paperboard, aluminum foil or plastic, to secure and protect the pills from external factors, such as humidity or dust.
Pharmaceutical practices often require a record of each patient's prescription and filled blister pack, to make sure an incorrectly filled blister pack can be detected and tracked-back in case of error. One quality assurance procedure consists in taking photographs of the blister packs after having been filled. When a blister pack comprises more than one prescription, it often becomes difficult to properly identify individual pills and assess that the prescription was correctly filled.
Hence, in light of the above, a need exists for a system and a method to overcome the aforementioned limitations of current filling systems.
According to an aspect, a tray system for filling pills into a blister pack is provided. The blister pack is provided with rows of pill-chambers. The system comprises a mounting tray, rows of lights, a depositing plate and a sliding tray.
The mounting tray is provided with rows of recesses and is shaped and configured to support the blister pack thereon. The pill-chambers are fitting in corresponding recesses of the mounting tray. The rows of lights are each facing one of the recesses of the mounting tray and are adapted to be turned on to illuminate the corresponding pill-chambers of the blister pack.
The depositing plate can be placed over the mounting tray and includes depositing-plate rows. The depositing-plate rows are facing the rows of the mounting tray and each row comprises side-by side pairs of pill-drop surface and a pill-hole. The pill-hole of each pair faces a corresponding pill-chamber of the blister pack. The sliding tray can be placed over the depositing plate and includes sliding-tray rows with opened cavities. The sliding tray can be slidable over the depositing plate from a pill-drop position to a chamber-filling position. In the pill-drop position, the opened cavities face the pill-drop surfaces, so that the pills can be dropped onto the pill-drop surfaces. In the chamber-filling position, the opened cavities face the pill-holes, so that the pills can be dropped into the pill-chambers of the blister-pack. In this way, when the sliding tray moves from the pill-drop position to the chamber-filling position, the pills are pushed from the pill-drop surfaces to the pill-chambers of the blister pack.
The depositing plate material can be selected to allow light emissions from the lights to pass through the pill-drop surfaces and hide the pills in the pill-chambers, when the sliding tray is in the pill-drop position. A user can, thus, see the diffused light from the corresponding pill-chambers into which the pills are dropped. Equally, a camera can detect the pills on the pill-drop surface of the depositing plate, while the pills already in the pill-chambers are hidden.
In some embodiments, the recesses of the mounting tray have a greater area or size than that of the pill-holes of the depositing plate.
In some embodiments of the tray system, the depositing plate material may include a blurring element. The blurring element may be adapted to allow the diffused light to pass through the depositing plate while dimming the view of the pills that are in the pill-chambers of the blister pack.
In some embodiments, the blurring element may be a textured surface composed of a plurality of prismatic shapes.
In other possible configurations, the blurring element may be a frosted surface treatment applied to the surface of the depositing plate.
In some embodiments, the frosted surface treatment is sanding the surface of the depositing plate.
In some embodiments, the frosted surface treatment is a translucent layer of paint applied on the surface of the depositing plate.
In some embodiments, the frosted surface treatment is a frosted film applied onto the surface of the depositing plate.
In some embodiments, the blurring element may be caused by the translucency of the depositing plate. The translucency of the depositing plate material may be between 25% and 75%, where 0% defines the material as completely opaque and 100% as completely transparent.
In some embodiments, the sliding tray material of the tray system may be the same material as the depositing plate.
In some embodiments, the sliding tray and the depositing plate may be linked together to form a sliding tray assembly. The link between the sliding tray and the tray assembly is made so that the sliding tray moves in parallel to the depositing plate when it transitions between the pill-drop position and the chamber-filling position.
In some embodiments, the tray system may further include a guiding element corresponding a receiving element. The guiding element can be provided on one of the sliding tray and the depositing plate. The corresponding receiving element can be provided on the other one of the sliding tray and the depositing plate. The guiding element can move along the corresponding receiving element, which can maintain the sliding tray parallel to the depositing plate during the transition between the pill-drop position and the chamber-filling position.
In some embodiments, the tray system may include a light board. The light board may be positioned underneath the mounting tray and is provided with the rows of lights.
In some embodiments, the tray system may further include a microcontroller and a wireless communication module. The microcontroller and wireless communication module can be provided to wirelessly control the lights of the lightboard. The communication module may also be a Bluetooth device.
In some embodiments, the tray system may also include a status device to indicate a status of the wireless communication module. The status device may be provided with status lights to indicate the status of the communication module.
According to another aspect, a method for filling pills into a blister pack is provided. The blister pack is as described above. The method includes general steps of supporting the blister pack on a mounting tray by fitting the pill-chambers in the corresponding recesses of the mounting tray. The method may include a step of placing a depositing plate and a sliding tray over the mounting tray. The depositing plate includes depositing-plate rows who are facing the rows of the mounting tray. Each depositing-plate row may include side-by side pairs of pill-drop surface and a pill-hole. The pill-hole of each pair faces a corresponding pill-chamber of the blister pack. The sliding tray may further include sliding-tray rows with open cavities. The sliding tray can be slidable over the depositing plate from a pill-drop position to a chamber-filling position. The method can include a step of illuminating the pill-chambers of the blister pack in which the pills must be dropped. Further, the method includes a step of dropping pills onto the pill-drop surfaces of the depositing plate. The opened cavities of the sliding tray are facing the pill-drop surfaces in the pill-drop position while dropping the pills.
When pills are dropped, a step of turning off rows of lights that are illuminating the pill-chambers. The lights are aligned with the recesses of the mounting tray corresponding to the pill-chambers. Once the rows of lights are turned off, the method may include a step of imaging the sliding tray with a camera to only detect pills on the pill-drop surface in the pill-drop position of the depositing plate, for verification purposes. When the sliding tray is in the pill-drop position, the depositing plate material allows the camera to detect the pills on the pill-drop surface while the pills already in the pill-chambers of the blister pack are hidden. After the event of imaging the sliding tray, the method includes a step of moving the sliding tray from the pill-drop position to the chamber-filling position. The pills are then pushed from the pill-drop surfaces into the pill-chambers of the blister pack.
In some embodiments, the method further includes a step of comparing images captured by the camera with information in a prescription and identify discrepancies between the images and the information in the prescription.

Each depositing-plate row comprises pairs 123 of pill-drop surfaces 124 and pill-holes 126, aligned side-by side with one another (i.e., also defined as transition sections). The pill-drop surface 124 may correspond to a substantially flat surface on which a pill can be dropped by a user. However, it should be noted that the pill-drop surface, may not be substantially flat and may be, for instance, bumpy or irregular. The pill-hole 126 may correspond to a hole adapted to allow the pill to fall inside the blister pack 80 pill-chamber 81. The pill-hole may be positioned underneath the depositing plate 120, and over the mounting tray 110. The pill-hole 126 of each pair 123 faces a corresponding pill-chamber 81 of the blister-pack. In some embodiments, the depositing plate 120 is placed over the mounting tray 110 and aligned so that each pair 123 faces a corresponding pill-chamber 81. In possible embodiments, the recesses of the mounting tray 110 have a greater area, or size, than the areas, or sizes, of the depositing plate pill-holes 126. In other possible embodiments, however, the recesses 112 (

In the illustrated embodiment, the material of the depositing plate is selected such as to allow light emissions or rays to pass through the pill-drop surfaces, allowing users to detect in which chambers the pills must be dropped, while hiding the pills already in the pill-chambers. As it can be appreciated, the material is selected such as to allow the camera to detect pills that have been dropped onto the pill-drop surfaces 124 by the user, while hiding the pills that are currently inside the pill chambers. A camera can therefore take a picture/image of the pills that have been dropped on the pill-drop surfaces 124 (such as the ones on the depositing plate 120) for verification purposes, allowing to keep track of the quantity and type of each individual pill contained within each individual pill-chamber of the blister pack, since they have been tracked/imaged at each step of the filling process. The material of the depositing plate 120 is selected to block from the pills from the view of the camera that have already been dropped in the blister pack. If needed, a professional or specialized application can later compare the images captured by the camera and identify any discrepancies between the pills on the pill-drop surfaces 124 and the information in the prescription file. In some embodiments, the images captured by the camera are stored on a computer, to be verified later on. For example, a pharmacist can use the images stored on the computer to verify that the technician has correctly filled pills in the blister pack, as indicated per prescription. Alternatively, a specialized software application can be provided with the computer to dynamically verify the content of the images and determine if the blister pack has been properly filled (i.e., assist or autonomously determine whether the content of the images contain the right prescription or amount and type of pills contained within the blister pack).
In some embodiments, the depositing plate 120 material is blurred or comprises a blurring element 106. As stated above, this blurring feature has the advantage of allowing diffused light from the light board to pass through the depositing plate 120 material, while dimming the view of the pills in the pill-chambers of the blister pack. In the present embodiment, as illustrated in
Once the images/pictures of the “sliding tray assembly” are taken in the pill-drop position 102, the sliding tray can be moved from the pill-drop position 102 to the chamber-filling position 104 (as illustrated in

Referring again to
It will be appreciated from the foregoing disclosure that the tray system provided herein allows the validation of pills throughout the filling process of the blister packaging. Among other things, the fact that some of the components of the tray system are provided with blurring elements that allow a camera to photograph individuals pills and assess whether the prescription was filled properly, while indicating to a professional how the pills should be filled in a blister pack.
While the tray system has been described in conjunction with the exemplary embodiment described above, many equivalent modifications and variations will be apparent to those skilled in the art when given this disclosure. Accordingly, the exemplary embodiment set forth above is considered to be illustrative and not limiting. The scope of the claims should not be limited by the preferred embodiment set forth in this disclosure but should be given the broadest interpretation consistent with the description as a whole.
