This application claims priority to U.S. Provisional Patent Application No. 61/439,321, filed Feb. 3, 2011, entitled “SYSTEM AND METHOD FOR PACKAGED MEDICAMENT INSPECTION,” which application is incorporated herein by reference in its entirety.
FIELD OF THE INVENTIONThe present invention relates to the inspection of receptacles, or packages, for unit-dose medicaments. The invention is particularly apt for automated inspection implementations.
BACKGROUND OF THE INVENTIONUnit-dose packaging approaches are being utilized in medical care facilities to provide predetermined unit-dose medicaments. By way of example, unit-dose packaging systems may be implemented within a medical dispensary (e.g., a pharmacy) located at a hospital or other patient care facility, wherein the medical dispensary packages a unit-dose medicament in a sealed package for distribution within the medical facility and administration to a patient located at the medical facility. In conjunction with such systems, the accuracy, integrity and reliability of packaged contents is a primary concern. Further, the efficiencies associated with such packaging is of particular interest.
Despite numerous advances made to date, the present inventors have recognized the desirability of providing an improved system and method for packaged unit-dose medicament inspection, wherein packaged contents may be inspected in conjunction with packaging operations to improve the accuracy, integrity and reliability of packaging and overall packaging efficiencies.
SUMMARY OF THE INVENTIONAn improved system and method for handling and inspecting receptacles containing corresponding predetermined unit-dose medicaments is provided. By way of example, such “predetermined unit-dose medicaments” may be in the form of pills, tablets, capsules, blister packs (e.g., hand-cut or automated, machine cut), vials, or any other configuration or packaging utilized for a single dose of a given medicament to be administered to a patient.
In one embodiment, a system for handling a given unit-dose receptacle may include at least a first imaging device for obtaining at least one image of the given receptacle and providing a first output signal corresponding therewith. The system embodiment may further include a processor (e.g., a digital signal computer processor) operable for processing the first output signal to extract corresponding first image data and for comparing the first image data with stored data. For a given receptacle, the stored data may correspond with at least one of a predetermined attribute of the corresponding, predetermined unit-dose medicament and/or a predetermined attribute of the given receptacle.
Inspection of a given receptacle after the intended filling of such receptacle with a corresponding predetermined unit-dose medicament may yield a number of advantages. For example, post-filling inspection allows for the identification of instances where a given receptacle fails to include the intended unit-dose medicament and/or the correct dosage of the medicament and/or where the packaged medicament is in a damaged condition. Further, such inspection allows receptacles having identified configuration discrepancies to be identified. For example, receptacles having edge seals and/or apertures (e.g., for hanging the receptacles) that vary from a predetermined standard may be readily identified. In turn, non-compliant receptacles may be handled accordingly and/or corresponding production equipment may be serviced.
In one approach, the first imaging device may include an imaging signal source for providing an imaging signal (e.g., an electromagnetic radiation signal such as a visible and/or infrared light signal), and an imaging signal detector for detecting at least a portion of the imaging signal and providing the first output signal. In one approach, the imaging signal source may be positioned on and illuminate a first side of the receptacle and the imaging signal detector may be positioned on a second side of the receptacle to receive portions of the imaging signal passing through the receptacle which are not otherwise blocked by the contents of the receptacle (e.g., a “back-light” approach). In another approach, the imaging signal source may be positioned on and illuminate a first side of the receptacle and the imaging signal detector may also be positioned on the first side of the receptacle (e.g., a “front-light” approach). In either approach, a digital camera may be employed as the imaging signal detector, wherein the digital camera may provide the output signal in a digital form to the processor.
As noted, the processor may be operable to extract first image data in relation to each given receptacle. In some embodiments, such first image data may comprise one or more of a contents-related group consisting of: data relating to a presence of an object within the given receptacle; data relating to a number of objects within the given receptacle; data relating to a shape, or pattern, of an object within the given receptacle; and data relating to a size (e.g., a measureable physical parameter) of an object within the given receptacle. In this regard, the processor may utilize stored software algorithms and/or other processing logic to extract the first image data, including for example edge-detection software algorithms, corner/interest point detection software algorithms; and/or blob detection software algorithms.
In various embodiments, the system may further include a database for storing data corresponding with at least one predetermined medicament attribute of the predetermined unit-dose medicament corresponding with a given receptacle, such attribute being one or more of a first predetermined group consisting of: a predetermined number of physically discrete units comprising the corresponding predetermined unit-dose medicament (e.g., typically one (1)); a predetermined shape, or pattern, of each physically discrete unit comprising the corresponding predetermined unit-dose medicament (e.g., circular, rectangular, oval, etc.); and a predetermined size of each physically discrete unit comprising the corresponding predetermined unit-dose medicament (e.g., as reflected by measured cross-dimensions, perimeter, area, etc.). Such stored data may be previously input into the system based upon measured, statistically-established parameters and/or otherwise pre-established, acceptable patterns, corresponding with each given predetermined unit-dose medicament. For each attribute, the stored data may comprise a predetermined range of acceptability, e.g., established based on appropriate input and/or empirical data.
As may be appreciated, comparison of extracted contents-related image data with corresponding stored medicament-related data allows the inspection system to identify instances in which a given package fails to include the intended predetermined medicament (e.g., as reflected by a size or shape that does not correspond to the intended unit does medicament) and/or the proper unit-dose of such medicament (e.g., to many separate pills) and/or in which the packaged medicament is in an unacceptable damaged condition (e.g., fractured pills, broken vials, etc.).
In some embodiments, for each given receptacle, the processor may be operable to extract first image data that may comprise at least one of a receptacle-related group consisting of: data relating to a shape of a predetermined sealed region of the given receptacle; data relating to a shape of a predetermined edge portion of the given receptacle; and data relating to a light transmissivity of a predetermined region of the given receptacle. In such embodiments, the processor may utilize corresponding stored software algorithms and/or other processing logic to extract the first image data, including for example edge-detection software algorithms, core-interest point detection software algorithms, interest point detection software algorithms, and/or blob-detection software algorithms.
In conjunction with such embodiments, the system may include a database for storing data corresponding with at least one predetermined attribute of the given receptacle, such attribute being one or more of a second predetermined group consisting of: a predetermined shape of the predetermined sealed region of the given receptacle; a predetermined shape of the predetermined edge portion of the given receptacle; and a predetermined light transmissivity of the predetermined region of the given receptacle. As may be appreciated, comparison of extracted receptacle-related image data with stored receptacle data allows the inspection system to identify instances in which a given receptacle has a configuration and/or seal condition of concern. For example, peripheral and aperture edges may be identified that indicate a potential receptacle condition of concern and/or which otherwise indicate that corresponding production equipment may be in need of maintenance, etc. For each attribute, the stored data may comprise a predetermined range of acceptability, e.g., established based on appropriate input and/or empirical data.
In some implementations, the system may include at least a second imaging device for obtaining at least another image of the receptacle and providing a second output signal corresponding therewith, wherein the processor is operable to process the second output signal to extract the second image data. In such arrangements, the processor may be operable for comparing the first image data with stored data corresponding with at least one predetermined attribute of the unit-dose medicament, and the same or another processor may be operable for comparing the second image data with stored data corresponding with at least one predetermined attribute of the receptacle. In this regard, the first image data may correspond with at least one of a contents-related group as noted above, and the second image data may correspond with at least one of a receptacle-related group as noted above.
In one approach, the processor may be operable to output an alert signal when comparison operations by the processor indicate that the presence of a predetermined condition. By way of example, such predetermined condition may be one corresponding with potential concern regarding whether the intended content (e.g., unit-dose medicament) is present and/or whether the content is in an appropriate condition. Additionally and/or alternatively, such predetermined condition may correspond with a potential concern regarding the size, configuration and/or condition of a given receptacle.
The alert signal may be in the form of an audible and/or visible output at a user interface. The system may be operable to allow a user to selectively view the image(s) corresponding with the given receptacle having the predetermined condition and/or one or more image(s) of an acceptable configuration corresponding with the intended unit dose medicament of the given receptacle.
In various implementations, the system may comprise automated componentry as will be further discussed. Further, the system may be networked with additional computer databases comprising stored medicament-related data.
As may be appreciated, an inventive method is also provided. The method is employable in handling one or a plurality of receptacles for separately containing a corresponding unit-dose medicament. For each given receptacle, the method may include obtaining at least one separate image of the receptacle, and processing the image to extract corresponding image data. In turn, for a given receptacle the method may further include the step of comparing the extracted image data with stored data. The extracted image data and stored data may correspond with a predetermined attribute of the corresponding unit-dose medicament and/or of the given receptacle. As may be appreciated, comparison of image data after intended filling of a given receptacle with a corresponding unit-dose medicament provides reliability and handling advantages.
The predetermined medicament attribute data corresponding with a given unit-dose medicament may comprise: a predetermined number of physically discrete units comprising the corresponding predetermined unit-dose medicament (e.g., typically one (1)); a predetermined shape, or pattern, of each physically discrete unit comprising the corresponding predetermined unit-dose medicament (e.g., circular, rectangular, oval, etc.); and/or a predetermined size of each physically discrete unit comprising the corresponding predetermined unit-dose medicament (e.g., as reflected by cross-dimensions, perimeter, area, etc).
In this regard, and in another aspect, an inventive method may be provided for generating predetermined attribute data corresponding with one or a plurality of unit-dose medicaments for use in an inspection system. For example, such method may be employed in conjunction with a method for inspecting a plurality of receptacles for separately contained different corresponding ones of a plurality of unit-dose medicaments.
In conjunction with the generation of predetermined attribute data for a given unit-dose medicament, the method may include the steps of obtaining at least a first image for each of a corresponding plurality of medicament test samples, and extracting test image data from the images. In turn, each of the plurality of test samples may be inspected to identify acceptable ones. For example, such inspection may be manually completed by an operator of the process and/or in an automated manner (e.g., utilizing one or more software algorithms). The method may further include using the test image data corresponding with acceptable ones of the plurality of test samples to generate the predetermined attribute data for the given unit-dose medicament.
In some embodiments, the predetermined attribute data for one or each of a plurality of unit-dose medicaments may comprise corresponding pattern data indicative of at least one acceptable shape. In certain implementations the predetermined attribute data for one or each of a plurality unit-dose medicaments may comprise corresponding pattern data indicative of a plurality of acceptable shapes.
In some embodiments, for one or each of a plurality of unit-dose medicaments the predetermined attribute data may comprise corresponding size, or physical attribute, data corresponding with an acceptable one or more physical parameters (e.g., as reflected by cross-dimensions (e.g., length, width and/or thickness), perimeter, area, etc). In certain implementations, for one or each of a plurality of unit-dose medicaments the predetermined attribute, data may comprise corresponding size, or physical attribute data corresponding with a plurality of acceptable physical parameters.
In some implementations, the method may include the step of sealably closing a given receptacle prior to the obtainment of the corresponding separate image(s) of such receptacle. In this regard, such closing step may be completed after intended filling of a given receptacle with the corresponding intended unit-dose medicament.
In conjunction with the method embodiment, the obtainment of an image(s) may include the steps of illuminating one side of a given receptacle (e.g., via an imaging signal provided by an electromagnetic radiation source). In turn, the image(s) may be captured on another side of the given receptacle during a portion of the illuminating step (e.g., a “back-light” approach) and/or on the same side during a portion of the illuminating step (e.g., a “front-light” approach). In either approach, the image(s) may be captured by an imaging signal detector (e.g., a digital camera), wherein features of the receptacle and/or contents of the receptacle may be extracted from the image(s).
The extracted image data may comprise one or more of a contents-related group consisting of: data relating to a presence of an object within the given receptacle; data relating to a number of objects within the given receptacle; data relating to a shape of an object within the given receptacle; and data relating to a size of an object within the given receptacle. In turn, the comparing step for a given receptacle may include a comparison of the corresponding image data to stored data corresponding with at least one predetermined attribute of the corresponding predetermined unit-dose medicament. As noted, the at least one predetermined medicament attribute may be one of a first predetermined group consisting of: a predetermined number of physically discrete units comprising the corresponding unit-dose medicament (e.g., typically one (1)); a predetermined shape of each physically discrete unit comprising the corresponding unit-dose medicament; and a predetermined size of each physically discrete unit comprising the corresponding predetermined one of said plurality of unit-dose medicament.
Additionally and/or alternatively, the extracted image data for a given receptacle may comprise at least one of a receptacle-related group consisting of: data relating to a shape of a predetermined sealed region the given receptacle; data relating to a shape of a predetermined edge portion of the given receptacle; and data relating to a light transmissivity of a predetermined region of the given receptacle. In turn, the comparing step for a given receptacle may include a comparison of the extracted image data to stored data corresponding with at least one predetermined attribute of the given receptacle. The at least one predetermined receptacle attribute may be one of a second predetermined group consisting of: a predetermined shape of the predetermined sealed region of the given receptacle; a predetermined shape of the predetermined edge portion of the given receptacle; and a predetermined light transmissivity of the predetermined region of the given receptacle.
In certain embodiments, for a given receptacle, image obtainment may entail obtainment of at least a first image (e.g., for processing to extract the image data corresponding with at least one predetermined medicament attribute), and obtainment of at least a second image (e.g., for processing to extract image data corresponding with at least one predetermined receptacle attribute). In various approaches, a first image and a second image may be obtained at the same location or at different locations.
In some embodiments, the method may include a comparison step that provides for the identification of a given receptacle as being non-compliant when a discrepancy between image data and corresponding stored data exceeds a predetermined range. For example, in relation to a given extracted medicament-related attribute or receptacle-related attribute a comparison to the corresponding stored attribute may be conducted in a manner such that a given receptacle is only identified as being non-compliant if the comparison identifies a difference that exceeds a predetermined amount, magnitude, or variance.
In instances when a given receptacle is identified as non-compliant, embodiments may provide an output signal that causes the given receptacle to be discarded. For example, in automated implementations the receptacle may be automatically removed from production processing and a new receptacle may be utilized for the corresponding predetermined medicament.
Additionally and/or alternatively, when a given receptacle is identified as non-compliant, certain embodiments may provide an alert signal to a user (e.g., an audible and/or visible signal). In turn, the user may selectively determine an appropriate remedial action.
In some applications, the method may be provided to allow a user to selectively access and view the image(s) obtained with respect to a given receptacle identified as non-compliant. In turn, a user may take remedial action.
In various applications, a method embodiment may provide for locating a given receptacle at a predetermined fill location for intended receipt of the corresponding predetermined unit-dose medicament. In turn, a fill operation may initiate for the given receptacle. In some approaches, the method embodiment may further include closing a given receptacle after the receptacle has been located and the fill operation initiated. The closing step may be completed prior to or after the obtainment of one or more inspection images of the receptacle.
In various applications, one or more of the noted method embodiment steps may be completed in an automated fashion. Further, certain embodiments may provide for automated movement of a given receptacle between a plurality of different work stations, e.g., for filling, inspection imaging, etc. In this regard, the method is particularly apt for automated implementations in which a plurality of receptacles are automatically filled with corresponding predetermined unit-dose medicaments, that may be the same or different, and inspected for contents verification and receptacle integrity. Numerous additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the embodiment descriptions provided hereinbelow.
Increasingly, such dispensaries are at least partially automated and the illustrated embodiment is particularly apt for automated implementation.
The embodiment of
In primary implementations, a given receptacle may be provided in a closed condition (e.g., sealably closed). In other implementations, the receptacle may be provided with an open port.
As shown in
Following image acquisition, the embodiment includes processing the image(s) to extract image data (step 3). In this regard, image processing may entail processing a digital image signal to detect features and extract image data regarding such features, e.g., utilizing a computer processor and software algorithms. In particular, image data may be extracted that is indicative of the presence of and/or one or more physical attributes of contents (e.g., objects) located within the receptacle and/or indicative of one or more physical attributes of the receptacle. For such purposes, one or more of the following types of software algorithms may be employed: edge-detection software algorithms; corner/interest point detection software algorithms; and/or blob detection software algorithms.
Extracted image data that may be indicative of a physical attribute of the content of a receptacle may include: data relating to a presence of an object within the given receptacle; data relating to a number of objects within the given receptacle; data relating to a shape, or pattern, of an object within the given receptacle; and, data relating to a size of an object within the given receptacle (e.g., a measureable physical parameter such as a length, width, thickness, perimeter, area, etc.). Extracted image data that may be indicative of one or more physical attributes of a receptacle may include: data relating to a shape of a predetermined sealed region of the given receptacle; data relating to a shape of a predetermined edge portion of the given receptacle; and data relating to a light transmissivity of a predetermined region of the given receptacle.
The method embodiment may further provide for a comparison of the extracted image data to stored data (step 4). Again, such comparison may be carried out by a computer processor and associated software.
The stored data may be indicative of one or more predetermined physical attributes of the corresponding unit-dose medicament that was located within or intended for location within the given receptacle. By way of example, such predetermined medicament attribute may correspond with one or more of the following: a predetermined shape, or pattern, of the given unit-dose medicament; a predetermined physical parameter, or size, of the given unit-dose medicament (e.g., a measureable physical parameter such as a length, width, thickness, perimeter, area, etc.); a predetermined number of physically discrete units corresponding with the given unit-dose medicament (e.g., typically one).
In turn, a comparison may be completed to determine whether extracted image data corresponding with a physical attribute(s) of any detected object within the receptacle is within a predetermined range of, or variance relative to, a corresponding acceptable predetermined physical attribute of the corresponding unit-dose medicament (step 4a). Such predetermined range may be established to provide a high degree of unit-dose medicament inspection reliability, while reducing instances of false failed inspections (e.g., instances in which an acceptable packaged unit-dose medicament fails inspection).
Stored data may also be indicative of one or more predetermined physical attributes of an acceptably configured, and preferably sealably-closed, receptacle corresponding with a given unit-dose medicament. By way of example, such predetermined receptacle attribute may correspond with one or more of the following: a predetermined shape of said predetermined sealed region of said given one of said plurality of receptacles; a predetermined shape of said predetermined edge portion of said given one of said plurality of receptacles (e.g., a peripheral edge or aperture edge); and, a predetermined light transmissivity of said predetermined region of said given one of said plurality of receptacles.
In turn, a comparison may also be completed to determine whether extracted image data corresponding with a physical attribute of the corresponding receptacle is within a predetermined range corresponding with such physical attribute (step 4b). Again, a predetermined range may be established to provide a high degree of receptacle inspection reliability, while reducing instances of false failed inspections (e.g., instances in which an acceptable receptacle fails inspection).
In instances where a given inspection comparison is outside of a corresponding predetermined range (e.g., pursuant to step 4a and/or step 4b above), the corresponding receptacle may be discarded (step 5). By way of example, the corresponding receptacle may be automatically diverted from an automated material handling system. Additionally and/or alternatively, an alert signal may be provided to a user.
When a given receptacle passes all corresponding inspection comparisons, the receptacle may be provided for further handling (step 6). By way of example, such receptacle may be automatically transported to a predetermined location for storage and/or dispensation to medical personnel for administration to a patient.
The embodiment of
Next, an open port receptacle may be produced for receipt of the specified unit-dose medicament (step 11). In this regard, a computer database may be accessed that comprises data corresponding with an appropriate predetermined receptacle for receiving the specified unit-dose medicament. By way of example, the computer database may comprise information regarding the size, configuration and/or other attributes of an appropriate predetermined receptacle for receiving the specified unit-dose medicament. As shown in
By way of example, in arrangements adapted for packaging utilizing flexible polymer-based receptacles, cylindrical sleeves of plastic may be utilized to define disposable plastic bag-like receptacles of a predetermined configuration (step 11a). By way of example, one or more reels of plastic sleeves having corresponding predetermined diameters may be cut to one or more predetermined lengths to define cylindrical sleeve sections of predetermined volume. In turn, a bottom edge of each cut sleeve section may be sealed (e.g., by welding) (step 11b). Upon such bottom edge sealing, an open port receptacle may be defined.
After or prior to such open port receptacle production, a machine-readable marking may be provided that comprises data that identities a given unit-dose medicament to be located within a given receptacle (step 12), e.g., a machine-readable marking that identifies a unit-dose medicament by pharmaceutical description, source, dosage, etc. By way of example, a machine-readable marking (e.g., a barcode) may be located (e.g., printed) on a predetermined portion of a cylindrical sleeve to be cut or previously cut (e.g., either before or after bottom edge sealing).
The presence and accuracy of the machine-readable marking may be verified for each given receptacle. By way of example, a wireless reader may be positioned relative to the corresponding cylindrical sleeve portion for a given receptacle and utilized to provide an output signal indicative of any machine-readable data provided on the predetermined portion of such cylindrical sleeve. In turn, the data read from the predetermined portion may be compared with stored data indicative of the intended, given unit-dose medicament to be located within the receptacle. Further, a signal may be provided to reinitiate the provision, filling and inspection of another receptacle for the corresponding predetermined unit-dose medicament.
In the event that such comparison fails to indicate a match, the corresponding receptacle may be discarded. In the event a match is indicated, the corresponding receptacle may be located for filling with the intended unit-dose medicament. In turn, and by way of example, the filling of the given receptacle may be completed in an automated fashion. In an automated filling approach, the open port of a given receptacle may be disposed for receipt of the corresponding unit-dose medicament therewithin. In turn, an insertion device may be utilized to automatically insert the corresponding unit-dose medicament into the receptacle.
Upon filling a given receptacle, the receptacle may be closed. By way of example, after location at a filling station and initiation of a filling operation a given receptacle may be automatically sealed at its open port (e.g., via welding). In turn, upon closure of a given receptacle, the receptacle may be provided for inspection, such as that described hereinabove in relation to

The automated filler device 138 may also include a second portion for staging the various unit-dose medicaments to be inserted. Optionally, the second portion may interface with a manually operated or automated input port 200.
Upon completion of an automated fill operation, controller 102 may provide a control signal so that the rotatable support platform 120 rotates to position the receptacle at a fourth work station location 124. An automated receptacle sealing device 140 may be located at the fourth work station location 124.
