Referring generally to the figures, various embodiments of a pharmaceutical filling system configured to facilitate filing (e.g., manual filing) of a multi-compartment pharmaceutical tray and related method are shown. Generally, the tray includes multiple compartments or wells each configured to hold one or more medication/pharmaceutical items and/or one or more medical items, and the tray typically is filled with more than one different type of pharmaceutical item at a time. The system includes a display device configured to display information representative of each type of pharmaceutical adjacent to the wells/channels of the tray in a manner that directs the filling of the well with the appropriate pharmaceutical.
In some embodiments, the system includes a filling workstation having a tray support device. The tray support device includes a display device surrounded by a support housing such that the display screen is positioned below the tray during filling. During the tray filling processing, the display device displays information (e.g., images, alphanumeric information, etc.) in various positions on the display device such that the information displayed is viewable through the bottom wall of the wells of the tray. The information displayed provides an indication of the type of pharmaceutical that is to be placed within the well through which the information is viewable. During filling of the tray, the user (e.g., health care personnel, pharmacist, pharmacy technician, etc.) is able to see the displayed information displayed below each well and places the pharmaceutical that corresponds with the displayed information into the well. Following filling of the tray with the appropriate pharmaceutical in each well, the filled tray may be used to load the pharmaceuticals into an automated packaging system which then packages each of the loaded pharmaceuticals into the desired packaging (e.g., unit dose packaging, packaging along with other pharmaceuticals for a particular patient, belt packages, etc.).
Referring to
With compartments 12 and drawer 16 filled, cabinet 10 is used to individually package pharmaceuticals based on prescription information received by the cabinet. In one particular embodiment, cabinet 10 is configured to dispense the appropriate type and quantity of the different pharmaceuticals that make up a prescription for a patient and to package the pharmaceuticals in a strip-type package. In one particular embodiment, cabinet 10 is a FastPak EXP available from AmerisourceBergen Technology Group.
Referring to
With tray 20 properly positioned on drawer 16, levers 28 are actuated causing the bottom walls/panels which close wells 22 to slide open allowing the pharmaceutical within each well 22 to fall into the corresponding well 18 of drawer 16. In one embodiment, tray 20 includes a single planar wall on each half of tray 20 that extends along the lower surface of tray 20, and the wall forms the bottom wall of all of the wells 22 on each half of tray 20. Levers 28 on each half of tray 20 are coupled to the walls such that as levers 28 are moved laterally within slot 32, the bottom walls are moved out from under wells 22 allowing the pharmaceutical within each well 22 to fall into the corresponding well 18 of drawer 16. Once drawer 16 is filled, tray 20 is removed from on top of drawer 16, and drawer 16 is retracted into the body of cabinet 10. Cabinet 10 is then ready to dispense the pharmaceuticals from drawer 16 as needed.

Referring to
In various embodiments, tray support 42 includes an alignment structure configured to engage tray 20 such that tray 20 is only permitted to seat tray support 42 in the proper positioning. In the embodiment shown in
Tray 20 also includes a identification tag, shown as tray barcode 58, that uniquely identifies tray 20. Barcode 58 will be read prior to filling tray 20 with pharmaceuticals at workstation 40. The tray identification information read from barcode 58 is then associated with data indicating which pharmaceuticals are to be loaded into tray 20 (e.g., a tray fill order as discussed below), and thus, during loading of cabinet 10 the identity of tray 20 is read and information indicating which pharmaceuticals are loaded in each cell of tray 20 (and consequentially in each corresponding well of drawer 16) is stored within database 45 associated with cabinet 10 to track which pharmaceuticals have been loaded into cabinet 10. Database 45 and the related control software utilize the information indicating which pharmaceuticals are located in each cell of drawer 16 to control cabinet 10 to properly dispense the desired pharmaceutical from drawer 16 during packaging.
In one embodiment, barcode 58 may be read using an external barcode reader 46. In another embodiment, tray support 42 may include a barcode reader directly coupled to support housing 50. In this embodiment, workstation 40 is configured to automatically read the barcode upon mounting of tray 20 onto tray support 42. In another embodiment, the identification tag is an RFID tag, and tray support 42 includes an RFID reader. In another embodiment, the identification tag is a label including a unique alphanumeric code that the user of workstation 40 enters (e.g., via keyboard) prior to filling tray 20.
After tray 20 is seated onto tray support 42 and the ID tag of tray 20 is read, workstation 40 (e.g., under the control of controller 48) is configured to assist the user of workstation 40 to properly place the correct pharmaceuticals into wells 22 of tray 20. As discussed in more detail below, various information and instructions are displayed to the user via display 44 to guide the user through the tray filling process. For example, instructions to fill certain wells 22 of tray 20 with a particular pharmaceutical may be displayed on display 44. In one embodiment, the user of workstation 40 retrieves a container 60 of the needed pharmaceutical and scans a barcode on container 60 with scanner 46. Controller 48 of workstation 40 confirms that the proper pharmaceutical container was retrieved, and the user is instructed to fill one or more wells 22 of tray 20 with the pharmaceutical from container 60. When all required wells 22 of tray 20 have been filled from container 60, the user returns container 60 to storage and continues filling the remaining wells of tray 20 with the proper pharmaceuticals.
Referring to
In addition to displaying pharmaceutical images, controller 48 of workstation 40 may be configured to cause the display of alphanumeric information 66 representative of a pharmaceutical (instead of or in addition to images 62) at distinct spatial positions on screen 52 such that the alphanumeric information 66 is located below each well 22 of tray 20 that is to receive the pharmaceutical currently being filled. As explained in more detail below, once a first set of wells 22 are filled, images 62 and/or alphanumeric information 66 may be displayed beneath another set of wells indicating that the user is to fill those cells with a second type of pharmaceutical. This process repeats until there are no other pharmaceuticals to be loaded into tray 20.
In one embodiment, image 62 displayed is an image of the particular pharmaceutical to be placed into the corresponding well 22 of tray 20. Thus, the user of workstation 40 is able to compare the appearance of the pharmaceutical actually being placed into tray 20 with the image 62 being displayed to confirm that the proper pharmaceutical is being loaded into tray 20. In another embodiment, image 62 may be a generic image or graphic displayed to highlight which well 22 of tray 20 is to be filled. In one embodiment, alphanumeric information 66 may be a drug code for the drug being filled or the name of the drug being filled. In another embodiment, alphanumeric information 66 may be show the number of individual pills or tablets that are to be placed in the associated well.
In various embodiments, controller 48 of workstation 40 is in communication with a database, shown as database 45, and database 45 includes various data that is used by controller 48 to provide the functionality discussed herein. Database 45 is also in communication with cabinet 10 and also may include control software for controlling cabinet 10. In various embodiments database 45 includes one or more of the following types of data: tray data representative of the tray identifier, data representative of pharmaceutical or medical items to be manually placed in the wells of the pharmaceutical tray, data representative of the respective wells within which the respective pharmaceutical or medical items are to be placed, data representative of the pharmaceutical or medical items, association data which associates the pharmaceutical or medical identifier with the pharmaceutical or medical items, alpha numeric data associated with the pharmaceutical or medical items, expiration dates associated with the pharmaceutical or medical items, manufacturer information associated with the pharmaceutical or medical items and any other information which may be required for a particular application. In various embodiments, the prescription data is representative of information for a plurality of pharmaceutical, medication or medical items where such information includes at least data useable by the workstation to generate images for the plurality of medication items on the first and second displays. In various specific embodiments, the data from database 45 may be used by workstation 40 to generate of images for a plurality of pharmaceutical items on displays 44 and/or 52.
In various embodiments, each well 22 of tray 20 may be equipped with a sensor configured to detect when the well has been filled. In one such embodiment, bottom wall 64 may be a touch sensitive sensor such that each pill impact within well 22 is detected and counted. In another embodiment, each well 22 may be equipped with an infrared reflectance sensor, a capacitance sensor or proximity sensor configured to detect entry of each pill into well 22.
In the embodiments discussed above, tray 20 and workstation 40 are described primarily relating to filling a tray with pharmaceuticals and/or medical items. However in other embodiments, a tray 20 and workstation 40 can generally be equipped and/or configured to facilitate placement of other items into a multi-welled tray. In such embodiments, the information (e.g., an image, alphanumeric-information, etc.) displayed adjacent or below each well of the tray is representative of the item to be placed in the well.
Referring to
At step 102, the user selects an empty tray 20, and places the selected tray 20 onto tray support 42 of filling workstation 40. At step 104, a reading device (e.g., bar code scanner 46) reads the unique identifier of the tray 20 loaded onto tray support 42, and compares the read tray ID to database 45. At step 106, controller 48 confirms via the database check that the read tray ID has not already been assigned to a tray fill order. At step 108, if the comparison indicates that the tray 20 selected by the user has already been assigned to a tray fill order, controller 48 triggers the display of an error message on display screen 44 instructing the user of filling workstation 40 to select another tray. In one embodiment, at step 108, controller 48 triggers the display of the error message on display screen 52 located below tray 20.
If the selected tray 20 has not already been assigned a tray fill order, an unfilled tray fill order (e.g., the next tray order in the queue to be filled) is assigned to the tray (e.g., by associating the tray fill order with the tray ID in the database), and the process moves to step 110. In the various embodiments discussed herein, the tray fill order includes a list of each pharmaceutical to be filled into a particular tray 20 along with the assigned well 22 of the tray 20 that will contain a particular pharmaceutical after filling. At step 110, controller 48 displays information identifying the first pharmaceutical to be filled into tray on display screen 44 and also displays a prompt directing the user to retrieve the container holding the first pharmaceutical from a storage location (e.g., a shelf, drawer, etc.). In one embodiment, at step 110 information identifying the location of the first pharmaceutical may also be displayed.
After retrieval of the first pharmaceutical, the user scans the bar code on the pharmaceutical container using bar code scanner 46 of workstation 40. At step 112, controller 48 compares the scanned bar code to the expected bar code for the first pharmaceutical. If the scanned bar code does not match the expected bar code, at step 114, controller 48 displays an error message on display screen 44 and/or on display screen 52, and the user is prompted to retrieve the proper pharmaceutical container. If the scanned bar code matches the expected bar code, controller 48 determines that the user has selected to the proper pharmaceutical container, and at step 116, controller 48 displays a prompt to the user via display screen 44 instructing the user to enter the lot number and expiration date of the pharmaceutical (e.g., input received via keyboard associated with workstation 40 or via a touch screen version of display screen 44). In one embodiment, the lot number and/or expiration date of the pharmaceutical entered at step 116 is stored in database 45 and is associated with each tray well that holds the pharmaceutical. In this embodiment, packaging cabinet 10 has access to and may utilize the lot number and/or expiration date data during packaging of pharmaceutical. In one such embodiment, cabinet 10 is configured to access database 45 during packing of pharmaceuticals from tray 16 and to print or otherwise adhere a label onto the pharmaceutical package or pouch that indicates the lot number and/or the expiration date.
At step 118, controller 48 controls display 52 to display information (e.g., image information, alphanumeric information, etc. as discussed above) indicative of the first pharmaceutical beneath each well 22 of tray 20 that is assigned to receive the first pharmaceutical by the tray fill order. Because the bottom walls of the wells 22 of tray 20 are transparent, the user is able to see which wells 22 are highlighted by the display of information, and the user fills each highlighted well with the first pharmaceutical.
At step 120, controller 48 and/or the user determines whether there is a sufficient quantity of the first pharmaceutical within the container retrieved by the user to fill each of the wells 22 of tray 20 that are to be filled with the first pharmaceutical. If it is determined that the container retrieved by the user does not contain enough of the first pharmaceutical to fill each of the wells, the process moves to the step 150, discussed below. If it is determined that the container retrieved by the user does contain enough of the first pharmaceutical to fill each of the wells that should be filled with the first pharmaceutical, the user fills all of the wells 22 highlighted by the display of information as discussed above.
At step 122, the user indicates that each well 22 has been filled, for example by selecting a “done filling” button displayed on screen 44 (e.g., via selection by a mouse, or selection of a button on a touch screen version of screen 44). In an embodiment in which tray 20 is configured to detect filling of wells 22 using a sensor, controller 48 may be configured to automatically determine when filling is complete based on the data received from the sensors. At step 124, controller 48 stops displaying the information highlighting each of the wells 22 to be filled after controller 48 has determined that all required wells have been filled with the first pharmaceutical.
At step 126, controller 48 determines whether there are additional pharmaceuticals in the tray fill order that need to be added to the tray 20 currently located at fill workstation 40. If there are unfilled items in the tray fill order, steps 110-124 are repeated until all of the pharmaceuticals of the tray fill order have been added to the tray.

In an embodiment, shown in
Referring back to step 120, controller 48 and/or the user determines whether there is a sufficient quantity of the first pharmaceutical within the container retrieved by the user to fill each of the wells 22 of tray 20 that are to be filled with the first pharmaceutical. If it is determined that the container retrieved by the user does not contain enough of the first pharmaceutical to fill each of the wells, the process moves to step 150. At step 150, controller 48 and/or the user checks information regarding the current inventory and if there are other containers of the needed pharmaceutical available in the inventory, controller 48 causes the display of a prompt on screen 44 instructing the user to retrieve another container of the first needed pharmaceutical from a storage location. In one embodiment, controller 48 causes the display of information indicative of the storage location of the additional container. At step 152, the user indicates that the new container of the pharmaceutical has been retrieved by selecting a start new bottle icon displayed on screen 44.
Referring to
If at step 162, controller 48 determines that the lot numbers and expiration dates are different, at step 164, controller 48 causes screen 44 to display a prompt instructing the user to identify which wells 22 of tray 20 where already filled with the pharmaceutical. In one embodiment, controller 48 cause the display of an image of tray 20 on screen 44, and the user selects (e.g., via touch screen display 44, or via selection of the wells on the screen via a mouse), which wells of the tray were already filled. At step 166, when the user has selected all of the wells that were filled from the original pharmaceutical container, the user indicates completion by selecting an ok or step completed icon. At step 168, controller 48 stops the display information (e.g., images 62, alphanumeric information 66, etc.) on screen 52 beneath the wells 22 that were already filled but continues to display information (e.g., images 62, alphanumeric information 66, etc.) on screen 52 beneath the wells 22 that still must be filled with the pharmaceutical from the new container. Thus, after step 168, controller 48 only causes the display of information (e.g., images 62, alphanumeric information 66, etc.) on screen 52 beneath the wells 22 that still need to be filled, and then at step 170, controller 48 causes display 44 to display a prompt for the user to continue filling the tray, and the process passes back to step 120, and the rest of the tray is filled as discussed above.
Following step 150, at step 172, if no additional containers of the needed pharmaceutical are available, the user selects an icon indicating that no additional containers of the needed pharmaceutical are available. In one embodiment, controller 48 accesses inventory information directly to determine whether additional containers of the needed pharmaceutical are available, and in this embodiment, step 172 is skipped. At step 174, controller 48 causes screen 44 to display a prompt instructing the user to identify which wells 22 of tray 20 where already filled with the pharmaceutical. In one embodiment, controller 48 causes the display of an image of tray 20 on screen 44, and the user selects (e.g., via touch screen display 44, or via selection of the wells on the screen via a mouse) which wells of the tray were already filled with the needed pharmaceutical. At step 176, when the user has selected all of the wells that were filled from the original pharmaceutical container, the user indicates completion by selecting an ok or step completed icon. However, in an embodiment in which the wells of tray 20 are equipped to sense filling of the wells (e.g., via a touch sensitive bottom wall, etc. as discussed above), controller 48 may be configured to automatically determine that the wells have been filled based upon the data from the sensors. The information captured at step 174 and 176 is used by controller 48 and/or the control system of cabinet 10 to track which wells of tray 20 and of drawer 16 were not able to be filled as requested by the fill tray order. At step 178, the pharmaceutical that is out of stock is removed from the fill tray order, and the process passes back to step 126, and filling of the tray continues as discussed above.
As an alternative to the use of separate display device 52 and non-opaque, moveble well closure panels, it is also contemplated that display device 52 could be modified to also function as the closure panel. For example, a moveable, LED display panels could be used as the closure panels to eliminate the separate display device 52 and the need to index the tray to the display device. In this embodiment, the tray would include a wired or wireless interface to the workstation so that LED closure panels of the trays 18 could be controlled by the workstation 40 to generate the images required below each well 22. Additionally, this configuration may permit the elimination of the use of a barcode as the tray identifier. Rather, the tray identifier would be a code stored in the tray and read by the workstation 40 through the interface.
Referring to
In various embodiments, controller 48 is configured to alter the display of graphics on display 44 to facilitate the filling of tray 20. For example, in one embodiment, controller 48 is configured to display images of pharmaceuticals to be filled, for example images 202, within one or more well graphics 206 of image 200 that correlate to the wells 22 of tray 20 that are to receive a particular pharmaceutical. In another embodiment, controller 48 is configured to display alphanumeric information of pharmaceuticals to be filled, for example images 204, within one or more well graphics 206 of image 200 that correlate to the wells 22 of tray 20 that are to receive a particular pharmaceutical. In another embodiment, controller 48 is configured to display other graphics (e.g., change color, highlight, display “fill”, etc.) within or around one or more well graphics 206 of image 200 that correlate to the wells 22 of tray 20 that are to receive a particular pharmaceutical.
In this embodiment, graphic 200 on display 44 acts as a map or graphical directions to the user of workstation 40 regarding how tray 20 should be filled. In this embodiment, the user views graphic 200 to determine which of well graphics 206 are indicated (e.g., via graphics 202, alphanumeric info 204, or other highlighting) to receive a pharmaceutical. The user correlates the indicated well graphics 206 with the physical wells 22 in tray 20, and fills wells 22 accordingly. In this manner, controller 48 and the user substantially execute the method shown in
