The present invention relates to an automatic packager for medications. More particularly, the present invention relates to an automatic packager for pharmaceutical blister card packages.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
Pharmacies use several types of packaging to provide pharmaceutical products or medications to consumers. The types of packaging may include strip packages, blister cards, pill vials, and the like. Pill vials and strip packages are most appropriate for individual customers of retail pharmacies. However, institutional customers, for example, nursing homes, palliative or hospice facilities, hospitals, and the like use blister cards extensively.
In the example illustrated in
Automatic strip packages are now used in retail pharmacies to quickly and accurately package medications into strip packages. Automatic strip packagers have allowed pharmacies to fulfill more customer orders in a relatively short time and with more accuracy than hand-filling vials. Accordingly, more and more pharmacies are now using automatic strip packagers to serve individual customers. On the other hand, a majority of blister cards are still filled by hand. Hand filling is performed by placing the blister sheet 110 on a table or on a hand-filling machine. A technician or pharmacist then hand fills each blister compartment 120 before sealing the blister card 100. Hand-filling machines help verify accurate filling of the blister card 100 but do not themselves speed up the blister card 100 filling process.
Current blister card packagers available in the market are expensive, inefficient, and are generally not a good replacement for filling blister cards 100 by hand. Existing machines generally take up a large area and do not provide a cost benefit over hand filling the blister cards 100.

The reservoir cover 255 covers a portion (e.g., a spout portion 270) of the reservoir 250. The reservoir cover 255 is pivotably attached to the spout portion 270 to pivot between an open position and a closed position. When a pharmacist is emptying the contents of the cartridge 240, the reservoir cover 255 pivots to the open position to allow the medications 180 to flow out of the reservoir 250 into the bulk containers. During the dispensing process, the cartridge mechanism 245 includes a stopper 246 to inhibit the reservoir cover 255 from opening. As such, the medications 180 within the reservoir 250 are not accessible outside the machine during the dispending process.
Teeth 275 are provided on the outer circumferential surface of the wheel 260. During the dispensing process, the teeth 275 interlock with teeth of a shaft driven by a motor assembly of the cartridge mechanism 245. The wheel 260 is provided with three scooping members 265 to scoop individual medications 180 from the reservoir 250. The scooping members 265 include an inward projection 266 extending into the wheel 260. The curved surface of the reservoir 250 guides the medications 180 into the inward projections of the scooping members 265. The scooping members 265 include a stopper 268 along a circumferential end of the inward projections that hold the medications 180 when the wheel 260 is being rotated. Scooping members 265 may be made in different sizes to accommodate the different sizes of medications 180. The scooping members 265 can be swapped to configure the cartridges 240 to dispense medications 180 of different sizes. The scooping members 265 may also be removed for cleaning. In some embodiments, rather than being separate from the wheel 260, the scooping members 265 may be formed integrally with the wheel 260. In these embodiments, the wheels 260 or cartridges 240 may be swapped to dispense medications 180 of different sizes.
The wheel 260 includes holding pins 280 (see

Typically, a single LED device may be used below the platform 320 to illuminate the translucent platform 320. However, the single LED device may not provide uniform lighting through all of the surface area of the platform 320. Particularly, each LED device includes a light signature such that the center of the platform 320 is brighter than the edges of the platform. This irregularity in brightness may result in misidentifying medications 180 during the image recognition process. In order to provide uniform brightness across the surface are of the platform, several LED devices may be placed around the bottom surface of the platform. In some embodiments, the light signature of the LED device is detected and a backing (not shown) may be applied to the platform to correct the light signature of the LED device. The backing, when applied to the platforms 320, distributes the light from the LED device of the LED lighting system 322 such that every portion of the platform 320 is illuminated with similar brightness.
The shuttle 325 may be moved laterally between the platform 320, over the reservoir 250, and over a conduit 335. The shuttle 325 transfers the medications from the platform 320 either to the reservoir 250 or to the conduit 335. The shuttle 325 is driven by the shuttle drive 330. The shuttle drive 330 may be a motor assembly, an actuator, or the like that moves the shuttle 325 between the platform 320, over the reservoir 250, and over the conduit 335. In the example illustrated, the shuttle drive 330 includes a rotating screw 332 that moves the shuttle 325 laterally between the platform 320, the reservoir 250, and the conduit 335.
The camera system 305 includes a camera 340 and a mirror 345. The camera 340 is positioned at the back of the cartridge mechanism 245. The camera 340 may be a still camera or a video camera that captures an image of the contents of the platform. The mirror 345 is placed directly above the platform 320 and is tilted at a 45-degree angle such that the camera 340 positioned at the back of the cartridge mechanism 245 can capture an image of the platform 320.
The motor assembly 310 includes a motor 350 that drives a shaft 355 positioned in the middle of the cartridge mechanism 245. The shaft 355 includes teeth 356 that interlock with the teeth 275 of the wheel 260 (see
The PCB 315 includes the electrical components of the cartridge mechanism 245. The PCB 315 is positioned on the side opposite that of the wheel 260. In some embodiments, the PCB 315 includes an antenna 360 (see
The lockout mechanism 316 is, for example, a lockout solenoid that prevents a cartridge 240 from being loaded onto the cartridge mechanism 245 when the lockout mechanism 316 is activated. During a dispensing process, not all cartridge mechanisms 245 are used to fill a prescription. In these situations, the lockout mechanism 316 is used to prevent cartridges 240 from being placed on inactive cartridge mechanism 245. In addition, the lockout mechanism 316 may be used to prevent an incompatible or wrong cartridge 240 from being loaded to the cartridge mechanism 245. For example, the cartridge mechanism 245 may read the RFID tag 365 to determine whether the correct and compatible cartridge 240 is being loaded to the cartridge mechanism 245. The cartridge mechanism 245 may only deactivate the lockout mechanism 316 when the correct cartridge 240 is being loaded to the cartridge mechanism 245. The lockout mechanism 316 may also be used to prevent the cartridge 240 from being removed from the cartridge mechanism 245. Particularly, the lockout mechanism 316 locks the cartridge 240 in place when loaded on to the cartridge mechanism 245. During the dispensing process, the lockout mechanism 316 is activated to prevent removal of the cartridge 240. The lockout mechanism 316 may be deactivated when the dispensing process is complete and the cartridge 240 can be removed from the cartridge mechanism 245.
In some embodiments, the electronic processor 370 is implemented as a microprocessor with separate memory, such as the memory 375. In other embodiments, the electronic processor 370 may be implemented as a microcontroller (with memory 375 on the same chip). In other embodiments, the electronic processor 370 may be implemented using multiple processors. In addition, the electronic processor 370 may be implemented partially or entirely as, for example, a field-programmable gate array (FPGA), an applications specific integrated circuit (ASIC), and the like, and the memory 375 may not be needed or be modified accordingly. In the example illustrated, the memory 375 includes non-transitory, computer-readable memory that stores instructions that are received and executed by the electronic processor 370 to carry out the functionality of the cartridge 240 described herein. The memory 375 may include, for example, a program storage area and a data storage area. The program storage area and the data storage area may include combinations of different types of memory, such as read-only memory and random-access memory.
The transceiver 380 enables wired or wireless communication between the electronic processor 370 and a control system of the automatic blister card packager 200 and/or a control system of the packaging unit 210. In some embodiments, the transceiver 380 may include separate transmitting and receiving components, for example, a transmitter and a receiver.
The other components of the universal feed cassette 205 are described singularly with respect to a single cartridge mechanism 245. However, it should be noted that the descriptions and functionality are equally applicable for each cartridge mechanism 245 of the universal feed cassette 205. The camera system 305 receives control signals from the electronic processor 370. Based on the control signals received from the electronic processor 370, the camera system 305 controls the camera 340 and the lighting system that illuminates the platform 320. The motor assembly 310 may send position sensor signals to the electronic processor 370 and receive control signals to operate a motor of the motor assembly 310 based on the position sensor signals. As described above, the shuttle drive 330 may be a motor assembly or an actuator. The shuttle drive 330 may also include a position sensor to determine the position of the shuttle 325. The shuttle drive 330 may send the position sensor signals to the electronic processor 370, which sends control signals to the shuttle drive 330 to move the shuttle 325 based on the position sensor signals. In some embodiments, the shuttle system 300 may also include a shuttle home sensor, which indicates whether the shuttle 325 is at a home position. Signals from the shuttle home sensor are provided to the electronic processor 370 to control the movement of the shuttle 325.
The pill sensor 362 communicates with the electronic processor 370 to provide an indication of whether or not a pill is dispensed through the conduit 335. The electronic processor 370 also controls the indicator system 364 to provide an indication of the status of each cartridge 240. The indicator system 384 may include one or more LEDs provided behind a translucent plastic material. The electronic processor 370 may use the indicator system 384 to provide indications, for example, whether a cartridge 240 is correctly placed in the cartridge slot 220. The electronic processor 370 may activate, for example, a blue LED to indicate that a next cartridge 240 should be placed in the corresponding cartridge slot 220 (that is, the cartridge slot 220 corresponding to the cartridge mechanism 245 with the blue LED activated). The electronic processor 370 may activate, for example, a green LED to indicate that the cartridge 240 was correctly placed in the cartridge slot 220. The electronic processor 370 may activate, for example, a red LED to indicate that the cartridge 240 was not correctly placed in the cartridge slot 220. Additionally, the electronic processor 370 may use the indicator system 384 to provide indications on where to place a cartridge 240 and when to remove a cartridge 240. For example, the electronic processor 370 may activate a blue LED to indicate that a pharmacist can place a cartridge 240 in the cartridge slot 220 corresponding to the activated LED. The electronic processor 370 may activate a blue LED again to indicate that the dispensing process is complete and the cartridge 240 can be removed from the cartridge slot 220.
The method 385 also includes advancing, using the cam and follower mechanism 285, the holding pin 280 into the scooping member 265 (at block 395). Referring to
The method 385 further includes holding the medication between the holding pin 280 and the stopper 268 (at block 400). When the holding pin 280 is advanced, a medication 180 is held between the holding pin 280, the circumferential end of the scooping member 265, and the stopper 268. The medication 180 is held in such a way until the scooping member 265 moves past the top portion of the wheel 260.
The method 385 also includes rotating, using the motor assembly 310, the scooping member 265 past the top portion of the wheel 260 (at block 405). As discussed above, the motor assembly 310 rotates the wheel 260 to rotate the scooping members 265. The motor assembly 310 may also include a position sensor (not shown) to detect a position of the wheel 260. For example, the motor assembly 310 may include a hall sensor to detect magnets placed at certain locations on the wheel 260 to determine the position of the wheel 260. In other embodiments, the position sensor may be an optical sensor or the like.
The method 385 further includes retracting, using the cam and follower mechanism 285, the holding pin 280 to drop the medication 180 on to the platform 320 (or for example, a verification system that verifies that an expected medication 180 (e.g., correct, single, and unbroken medication 180) is delivered) (at block 410). Referring to
The automatic blister card packager 200 may pack only a single medication of a kind in any one blister compartment 120. Accordingly, the cartridge 240 may need to verify that an expected medication 180 (for example, a single unbroken medication 180) is dispensed to the packaging unit 210. The method 415 further includes determining whether only a single unbroken medication 180 is delivered to the shuttle system 300 (at block 425). This may also be referred to as singulation verification. The electronic processor 370 controls the camera system 305 to acquire an image of contents of the platform 320. The mirror 345 reflects the contents of platform 320 to the camera 340, which captures the image. The camera 340 provides the captured image to the electronic processor 370 for verification. The electronic processor 370 may use image recognition techniques on the captured image to ensure that only a single unbroken medication 180 is delivered to the shuttle system. Example image recognition techniques are described in U.S. Patent Application Publication No. 2018/0091745, the entire contents of which are hereby incorporated by reference.
When the electronic processor 370 determines that more than one medication 180 has been delivered to the shuttle system 300 or that a broken medication 180 has been delivered to the shuttle system 300, the method 415 includes returning the contents of the shuttle system 300 to the reservoir 125 (at block 430). The electronic processor 370 controls the shuttle drive 330 to move the shuttle 325 from the platform 320 to a first opening (e.g., the first position). The shuttle 325 returns the contents from the platform 320 to the reservoir 250 through the first opening. The method 415 returns to block 420 to deliver the next medication 180 to the shuttle system 300.
When the electronic processor 370 determines that only one unbroken medication 180 has been delivered to the shuttle system 300, the method 415 includes determining whether the correct medication 180 is delivered to the shuttle system 300 (at block 435). As described above, the electronic processor 370 may use the above incorporated image recognition techniques to determine whether the correct type of medication 180 has been delivered to the shuttle system 300.
When the electronic processor 370 determines that the incorrect type of medication 180 is delivered to the shuttle system 300, the method 415 moves to block 430 to return the contents of the shuttle system 300 to the reservoir 250, as described above. Accordingly, in blocks 410 and 420, the method 415 is determining whether an expected medication 180 is delivered to the shuttle system 300. In some embodiments, determining whether an expected medication 180 is delivered may include only one of the blocks 425 or 435 or the blocks 425 and 435 may be performed in a different order. In other embodiments, rather than checking for whether a single unbroken medication 180 is delivered to the shuttle system 300, determining whether an expected medication 180 may include determining whether a correct type of medication is delivered to the shuttle system 300 regardless of the number of medications delivered to the shuttle system 300. In yet other embodiments, determining whether an expected medication 180 may include determining whether a correct number of medications is delivered to the shuttle system 300.
When the electronic processor 370 determines that the correct type of medication 180 is delivered to the shuttle system 300, the method 415 includes delivering the medication 180 to the packaging unit 210 (at block 440). The electronic processor 370 controls the shuttle drive 330 to move the shuttle 325 from the platform 320 to a second opening (e.g., the second position). The shuttle 325 delivers the medication 180 from the platform 320 to the packaging unit 210 through the second opening, the conduit 335, and the dispensing opening.
The method 415 also includes verifying the delivery of the medication 180 to the packaging unit 210 (at block 445). The pill sensor 362 detects whether or not a pill was dispensed through the conduit 335 and provides indicating signals to the electronic processor 370. When the electronic processor 370 determines that a medication 180 was delivered to the packaging unit 210, the method returns to block 420 to deliver the next medication. When the electronic processor 370 determines that a medication 180 was not delivered to the packaging unit 210, the electronic processor 370 sends an interrupt to the control system of the automatic blister card packager 200 and returns to block 420 to re-deliver the medication 180.
An example cartridge 240 and cartridge mechanism 245 are described in U.S. Pat. No. 10,583,941, filed on Oct. 15, 2018, entitled “UNIVERSAL FEED MECHANISM FOR AUTOMATIC PACKAGER,” the entire contents of which are hereby incorporated by reference

Cameras are mounted at or near the junction of the conduits and the chute 230. Each camera is associated with one of the cartridge 240 supported in the universal feed cassette 205. The cameras are operable to determine whether the correct number and/or type of pharmaceuticals are being dispensed from the cartridges 240. In some embodiments, the cameras only look for the presence or absence of an object in the conduit. The cameras capture images of pharmaceuticals exiting the universal feed cassette 205 and compare features (e.g., color, contour, size, shape, inscription, etc.) of the pharmaceuticals to stored images of known pharmaceuticals. In some embodiments, recognition software may be employed to automatically compare the images captured by the cameras to stored images. In other embodiments, the captured images may be transmitted to a remotely-located pharmacist or technician who analyzes the images and verifies that the correct number and type of pharmaceuticals were dispensed. In further embodiments, the cameras may be infrared sensors that only detect whether an object (e.g., a pill) drops through the universal feed cassette 205, rather than identifying the particular type of pharmaceutical.

The rail drive 525 may be a motor assembly, an actuator, or the like that moves the packaging equipment 510 between the rear of the rail base 515 and the front of the rail base 515 along the length of the rail base 515. In the example illustrated, the rail drive 525 includes a rotating screw 545 that moves the packaging equipment 510 laterally between the rear of the rail base 515 and the front of the rail base 515 along the length of the rail base 515. The rotating screw 545 includes a magnetic end 550 at the end of the rotating screw 545. The magnetic end 550 attaches to a corresponding end 555 of the packaging equipment 510. The magnetic end 550 may include a magnet that attaches to magnetic material of the corresponding end 555. In some embodiments, the magnetic end 550 includes magnetic material that attaches to magnets 556 on or in the corresponding end 555. The rotating screw 545 moves the packaging equipment 510 between a first position (as shown in

The packaging plate 565 is attached to the base portion 575 of the packaging base 560 such that the packaging plate 565 is above the packaging base 560. Referring to
The packaging plate 565 also includes pickup portions 610 that extend from the blister card receiving portion 605, for example, on opposite sides of the blister card receiving portion 605. When a blister card 100 is filled, a user may pick the blister card 100 from the packaging plate 565 by placing the user's fingers in the pickup portion 610. In some embodiments, only a single pickup portion 610 may be provided or the pickup portions 610 may be provided on the same side or adjacent sides of the blister card receiving portion 605. The pickup portions 610 may be depressed to similar depth or different depth than the blister card receiving portion 605 to facilitate picking up of a filled blister card 100.
Referring to
In some embodiments, the packaging plate 565 and the packaging lid 570 are detachably attached to the packaging base 560. The packaging plates 565 and the packaging lids 570 may be provided in different sizes to accommodate blister cards 100 of different kinds, for example, from different manufacturers and/or having different sizes. In some embodiments, the packaging plates 565 and the packaging lids 570 may be provided in different sizes to accommodate manifolds or chutes having different sizes of medication dispensing openings. The packaging plate 565 and the packaging lid 570 can be detached from the base portion 560 to exchange with a packaging plate 565 and a packaging lid 570 of a different size.
The rail drive 525 moves the packaging equipment 510 to align the medication receiving openings 630 with the medication dispensing openings of the chute 230. When a new blister sheet 110 is placed in the packaging equipment 510, the rail drive 525 retracts the packaging equipment such that a first row of the medication receiving openings 630 (e.g., a front-most row of medication receiving openings 630) is aligned with the medication dispensing openings of the chute 230. When medication is dispensed from the chute to the blister compartments 120 of the first row, the rail drive 525 is actuated to move the packaging equipment 510 such that a second row of the medication receiving openings 630 is aligned with the medication dispensing openings of the chute 230. The rail drive 525 moves the packaging equipment 510 to successively align the rows of the medication receiving openings 630 with the medication dispensing openings of the chute 230. When the blister card 100 is filled, the rail drive 525 moves the packaging equipment 510 to the second position such that a user may replace the filled blister card 100 with an unfilled blister card 100.
In some embodiments, the blister card 100 may receive multiple medications in a single blister compartment 120. In these embodiments, a universal feed cassette 205 having multiple rows of cartridges 240 may be used. The universal feed cassette 205 may be stocked such that cartridges 240 including all the medications that are to be packaged in a single blister compartment 120 are provided in the same column. Cartridges 240 provided in the same column share the same track of the chute 230. Accordingly, when the universal feed cassette 205 is operated, the multiple medications that are to be received in the same blister compartment 120 are dropped together into the blister compartment 120 through the shared column. In some embodiments, the cartridges 240 including all the medications that are to be packaged in a single blister compartment 120 may be provided in different columns. In these embodiments, the rail drive 525 is operated to move the packaging equipment 510 around such that the blister compartments 120 are placed under different columns to receive the multiple medications.
As discussed above, when the packaging equipment 510 is in the second position, the user may pull the packaging equipment 510 to the third position to replace the blister card 100. When in the third position, the user may perform a first check or verification and observes the medication receiving openings 630 to ensure that no medications are stuck in the medication receiving openings 630 and that all the medications have transferred from the medication receiving openings 630 to the blister compartments 120 of the blister card 100 currently being filled. After the first check or verification, the user may open the packaging lid 570. When the packaging lid 570 is opened, the user may perform a second check or verification and observe the blister compartments 120 to ensure that the desired number of blister compartments 120 are correctly filled. The user may then place the label sheet 130 on the blister sheet 110 and press down to stick the label sheet 130 to the blister sheet 110. The label sheet 130 includes an adhesive to stick the label sheet 130 to the blister sheet 110. The user may then pick up the blister card 100 from the packaging plate 565 using the pickup portions 610. A new blister sheet 110 is then placed in the packaging plate 565 to fill the next blister card 100.
In some embodiments, a heating element 572 (shown in
In the example illustrated, the automatic blister card packager 200 includes a packager electronic processor 650, a packager memory 655, a packager transceiver 660, a packager input/output interface 665, and the rail drive 525. The packager electronic processor 650, the packager memory 655, the packager transceiver 660, the packager input/output interface 665, and the rail drive 525 communicate over one or more control and/or data buses (e.g., a communication bus 670).
The packager electronic processor 650 and the packager memory 655 may be implemented similar to the electronic processor 370 and the memory 375 respectively, as described above. The packager transceiver 660 enables communication from the automatic blister card packager 200 to the communication network 675. In other embodiments, the packager transceiver 660 may include separate transmitting and receiving components, for example, a transmitter and a receiver. The automatic blister card packager 200, through the communication network 675, may communicate with the cartridge mechanism 245.
As noted above, the automatic blister card packager 200 may include the packager input/output interface 665 (or more commonly referred to as a user interface). The packager input/output interface 665 may include one or more input mechanisms (e.g., a touch screen, a keypad, a button, a knob, and the like), one or more output mechanisms (e.g., a display, a printer, a speaker, and the like), or a combination thereof. The packager input/output interface 665 receives input from the input devices actuated by a user, and provides output to the output devices with which a user interacts. In some embodiments, as an alternative or in addition to managing inputs and outputs through the packager input/output interface 665, the automatic blister card packager 200 may receive user inputs, provide user outputs, or both by communicating with an external device, such as a console computer, over a wired or wireless connection.
The method 700 also includes aligning, using the rail drive 525, a first row of the medication receiving openings 630 with the medication dispensing openings of the chute 230 (at block 710). The packager electronic processor 650 controls the rail drive 525 to align the first row, for example, the front-most row of the medication receiving openings 630 with the medication dispensing openings of the chute 230. The method 700 further includes instructing the universal feed cassette 205 to dispense medications (at block 715). The universal feed cassette 205 controls the individual cartridge mechanism 245 to dispense medications to the packaging equipment 510 through the chute 230.
The method 700 also includes determining, using the packager electronic processor 650, that medications are dispensed (at block 720). The packager electronic processor 650 may determine that the medications are dispensed based on receiving an acknowledgement from the universal feed cassette 205. In some embodiments, the packager electronic processor 650 may implement a timer and determine that the medications are dispensed when the timer expires. In some embodiments, the packager electronic processor 650 uses the cameras or sensors placed near the conduits of the chute 230 to determine that a medication passed through the chute 230. The method 700 further includes determining, using the packager electronic processor 650, whether a blister card 100 in the packaging equipment 510 is filled (at block 725). The packager electronic processor 650 may determine that the blister card 100 is filled when the medications are dispensed to the last row of the medication receiving openings 630.
When the packager electronic processor 650 determines that the blister card 100 has not yet been filled, the method 700 includes aligning, using the rail drive 525, a next row of the medication receiving openings 630 with the medication dispensing openings of the chute 230 (at block 730). The packager electronic processor 650 controls the rail drive 525 to align the next row, for example, the second, the third, or the fourth row of the medication receiving openings 630 with the medication dispensing openings of the chute 230. In some embodiments, the electronic processor 650 implements a delay before aligning the next row. The delay may be selected to account for settling of the medication (e.g., after bouncing) in the blaster card 100. The method repeats blocks 715, 720, 725, and 730 until the blister card 100 is filled. When the packager electronic processor 650 determines that the blister card 100 has not yet been filled, the method 700 includes moving, using the rail drive 525, the packaging equipment 510 from the first position to the second position (at block 735). The packager electronic processor 650 controls the rail drive 525 to move the packaging equipment 510 from the first position to the second position as set forth above. The user then replaces filled blister card 100 with the next blister card 100 to be filled.
In some embodiments, the chute 230 may include two or more rows of medication dispensing openings such that more than one row of the blister compartments 120 can be simultaneously filled. In one embodiment having two rows of medication dispensing openings, a first row of medication dispensing openings draws medications from a first row of cartridges 240, and a second row of medication dispensing openings draws medications from a second row of cartridges 240. In this embodiments, the first row of medications dispensing openings may be used to fill the blister cards 100 while the second row of cartridges 240 is being refilled, and the second row of medications dispending openings may be used to fill the blister cards 100 while the first row of cartridges 240 are being refilled. Additionally, the first row of cartridges 240 may be used for a first medication and the second row of cartridges 240 may be used for a second medication, and so on, when the blister card 100 is being packaged with multiple medications. In one embodiment having four rows of medication dispensing openings drawing medications from four rows of cartridges 240, all four rows of medication dispensing openings may be used to quickly fill the blister card 100 in one go.
Although the illustrated packaging equipment 510 is moved linearly between positions by the rail drive 525, in other embodiments, the packaging equipment 510 may be moved in other manners and/or by other suitable means. For example, the packaging equipment 510 may be mounted on a plate (e.g., a turn-style plate) that is rotatable between positions. Alternatively, the packaging equipment 510 may be connected to a conveyor- or chain-style system that moves the packaging equipment 510 in a loop (e.g., forward and backward, and up and down). In such embodiments, the automatic blister card packager 200 may include more than one packaging equipment. For example, the automatic blister card packager 200 may include two packaging equipments, such that as one packaging equipment on one side of the turn-style plate or the conveyor-style system is being filled by the automatic blister card packager 200, the other packaging equipment on an opposite side of the turn-style plate or the conveyor-style system can be manipulated (e.g., inspected, opened/closed, refilled, etc.) by a user.
The illustrated automatic blister card packager 800 includes a universal feed cassette 805, a blister card packaging unit 810 (
In the illustrated embodiment, the universal feed cassette 805 includes sixteen cartridge slots 840. The cartridge slots 840 are configured to receive cartridges, such as the cartridges 240 shown in

In operation, the different manifolds 815, 815A and side-to-side movement of the blister card packaging unit 810 provide additional benefits for filling a blister card (e.g., the blister card 100 shown in
Using the first manifold 815, the cartridges may simultaneously (or relatively simultaneously) release pills to fill a row of compartments 120, the packaging unit 810 may index to the next row of compartments 120 along the first axis (i.e., the z-axis), and the process may repeat until all of the rows of compartments 120 are filled. In some embodiments, the cartridges may release a single pill into each compartment. In other embodiments, the cartridges may release multiple pills into each compartment (e.g., between two and eight pills, depending on the size of the compartment). While one row of cartridges (e.g., the bottom row) is being used to fill the blister card 100, the other row of cartridges (e.g., the top row) may be refilled by a user with the next desired type of pills, or vice versa. Such an arrangement may be particularly useful when the same type of pill is being filled in each compartment 120 of the blister card 100.
Alternatively, only some of the channels 870 may be used to fill the blister card 100. For example, only two of the cartridge slots 840 may include cartridges that contain the desired pills for a particular blister card. In such embodiments, only the channels 870 and outlets associated with those cartridges may be used to direct pills into the blister card 100. After particular compartments 120 in a row are filled, the packaging unit 810 may then move along the second axis (i.e., the x-axis) to fill additional compartments in the row. Once a complete row of compartments 120 is full, the packaging unit 810 may index to the next row of compartments 120 along the first axis (i.e., the z-axis), and the process may repeat. In some embodiments, a complete row of compartments 120 may not be filled before the packaging unit 810 moves on to the next row. Rather, the packaging unit 810 may “zig-zag” along the first and second axes to fill the compartments 120. During this time, the cartridges associated with the other cartridge slots 840 may be refilled, filled with pills for another order, or go unused. This process may be carried out using any number of cartridges and associated channels 870 of the manifold 815, such as one, two, three, four, five, six, or seven.
Using the second manifold 815A, only two of the cartridges (e.g., one of the cartridges associated with each shared channel 870A) may release pills. The pills are then delivered by the shared outlets into the associated compartments 120 of the blister card 100. After particular compartments 120 in a row are filled, the packaging unit 810 may then move along the second axis (i.e., the x-axis) to fill additional compartments 120 in the row. Once a complete row of compartments 120 is full, the packaging unit 810 may index to the next row of compartments 120 along the first axis (i.e., the z-axis), and the process may repeat. Such a process may be used to deliver a single pill to each compartment 120 of the blister card 100. Alternatively, multiple pills may be delivered to each compartment 120 of the blister card 100. For example, more than one cartridge associated with each shared channel 870A may simultaneously (or relatively simultaneously) release a pill into the shared channel 870A to deliver multiple pills to a single compartment 120. Alternatively, each cartridge may release more than one pill into the shared channel 870A. In some embodiments, a complete row of compartments 120 may not be filled before the packaging unit 810 moves on to the next row. Rather, the packaging unit 810 may “zig-zag” along the first and second axes to fill the compartments 120. While the desired cartridges are being used, the other cartridges may be refilled, filled with pills for another order, or go unused.
The cartridges in the cartridge slots 840 of the universal feed cassette 805 may be filled with the same type of pills or may be filled with different types of pills, as needed. As such, the compartments 120 of the blister card 100 may be filled with different pills and/or combinations of pills. For example, a first compartment 120 may be filled one pill of a first type, while a second compartment 120 may be filled one pill of the first type and one pill of a second type. Additionally, another compartment may include two pills of the second type, a pill of a third type, and a pill of a fourth type. As should be readily understood, any combination of number and types of pills per compartment 120 is possible, depending on the size of the compartment 120.
Since the blister card packaging unit 810 is movable side-to-side along the second axis (i.e., the x-axis), the processor of the automatic blister card packager 800 can identify which pills are located within which cartridge and generate an optimal path of travel for the blister card packaging unit 810. The processor can determine which type(s) of pills and how many pills are needed for each compartment, based on the prescription order. The processor can also optimize the path using a cost function based on, for example, how many pills are able to be dropped at a time, and the shortest travel distance to the next set of compartments 120. The processor can then send instructions to the rail drives 860, 875 to move the packaging unit 810. The processor can also send instructions to the universal feed cassette 805 to release pills from the cassettes at particular times. Using either manifold 815, 815A, different pills may be dropped into adjacent or non-adjacent compartments 120 of the blister card 100 at the same time to decrease the fill time of the blister card 100.
Thus, the invention provides, among other things, an automatic blister card packager. Various features and advantages of the invention are set forth in the following claims.
