Description

Description

The present invention relates to an apparatus for packaging individual portions of medication.

Corresponding apparatuses are also referred to as blister machines and are known from the state of the art. For instance, WO 2013/034504 A1 describes a blister machine that can be used in pharmacies and hospitals or, with appropriate dimensioning, also in blister centres, which compiles combinations of medication from several medication portions in a patient-specific manner in accordance with the medically prescribed administration times.

The apparatus packs medication compositions (which may comprise only a single portion of medication or a plurality of individual portions of medication) in correspondence to order data in a pack formed of a packaging material sheet, the so-called blister packs, wherein these packs exit the packaging apparatus as strand of blister packs (also referred to as "blister tubing") for further use. A blister pack regularly corresponds to a time when a patient takes the medication, i.e. it contains all the portions of medication that a patient must take at a given time of day. The order data itself may be, for instance, data derived from recipes or the like.

Familiar apparatus for packaging individual portions of medication comprises a plurality of storage and dispensing stations for portions of medication, which interact with a plurality of circulating guide means, which feed the portions of medication also to circulating collection means which feed the medication compositions to a packaging station, in which the blister packs are formed and individual portions of medication are introduced during the process of forming the blister packs. Due to special design of the apparatus described above, a plurality of blister packs per hour is produced, and appropriate identification of the blister pack is therefore of crucial importance.

Labelling of the blister packs after introducing individual portions of medication is not practicable, since the attachment, inter alia, characterising data of the contents of the blister pack will damage the portions of medication. The corresponding data is therefore attached before the actual blistering, i.e. the formation of the blister pack and the introduction of the portions of medication during the forming process. For this purpose, a labelling or printing apparatus is disposed before the actual packaging point, which applies the data corresponding to the order data to the packaging material, wherein this data uniquely identify the subsequently produced blister pack and reflect the content of each blister pack. DE 10 2008 047 975 A1 describes a method and an apparatus for the individual composition of tablets, wherein the tablets are introduced into the blister packs. The apparatus comprises a printer with which individual sachets are printed on the underside of the pack strip with a print, such as the name of a patient, the intended time of ingestion, etc. After blistering, the number of tablets in the blister is determined with a camera and compared with a target amount.

If a (systematic) error occurs during the application of the data to the packaging material (print image blurred or unreadable, offset, partially applied), this cannot or can hardly be found by a user due to the working speed and the type of data applied (bar code or similar) so that, if necessary, a large number of flawed blister pack will be made before the error is noticed by a user.

It is therefore an object of the present invention to provide an apparatus for packaging individual portions of medication, with which the number of flawed produced blister packs is reduced. It is a further object of the present invention to provide a corresponding method.

The object is met by an apparatus for packaging individual medicament portions according to claim 1. The apparatus according to the invention comprises a plurality of storage and dispensing stations for dispensing individual portions of medication, at least a guiding and collecting arrangement for receiving the portions of medication dispensed from the storage and dispensing stations and forwarding these portions of medication to a packaging station coupled to a control device comprising a supply of provided packaging material, forming stranded blister pack shapes and introducing the dispensed portions of medication when forming the blister packs into the blister packs. Depending on the exact configuration of the apparatus, one or a plurality of guiding and collecting arrangements may be used. This can or may be made in one piece, but it is also envisaged that the guiding and collecting means comprise separate guide and collecting means.

The apparatus further comprises a labelling or printing station coupled to the control apparatus and arranged in front of the packaging station for applying data predetermined by the control device in a predetermined arrangement to the packaging material of each blister pack to be formed in the packaging station.

The data to be applied are in a predetermined order, i.e. applied to a predetermined portion of the packaging material (and thus the subsequent blister pack), and, inter alia, may comprise the date of manufacture of the blister pack, the exact contents and possibly information on the expiration date of the contents of the blister pack. The manner of application of the data is not essential in the present invention. Thus, the data can be printed on the packaging material, but it is also conceivable that previously printed labels are attached to the packaging material at the predetermined location. Furthermore, it is not essential what type of data is applied. Thus, it is possible for the data is "readable" for a user, i.e. that, for instance, the name of the patient and the contents of the blister pack, hence the type of individual portions, secondary or possibly other data, are printed or glued in place. However, it is also conceivable that only a bar code is applied, which later may be supplemented or replaced by further data. Depending on the respective embodiment, the labelling or printing station and the packaging station may be a group of components. Alternatively, the labelling or printing station may be a separate component, which may improve the accessibility in the event of a fault.

Independently of type of application of data and type of data itself, it is essential that the applied data is readable by a user or machine at a later stage.

The apparatus according to the invention further comprises an optical detection device coupled to the control device that optically detects the data of individual blister packs of the strand applied by the labelling or printing station, and an evaluation device coupled to the control device that compares the data acquired from a single blister pack with the desired features. The evaluation device can be integrated in the control device. It is also conceivable that the function of both devices is performed by a common component, for instance a computer.

For instance, the data collected may only be the position for the application of data to the blister pack. If it is determined in a comparison with desired features that the data is applied at a position that is unsuitable for a subsequent machine data acquisition, this may indicate a systematic error in the application of data (for instance, if five or more blister packs in a row have the same error), and the apparatus is possibly stopped, wherein the exact responses to the determination of a deviation between detected data and desired features is dependent upon the type and frequency of the deviations.

For storing the manufactured strand of connected blister packs, the apparatus according to the invention further comprises a storage station in which the strand is stored in an orderly manner. By an "orderly" storage, one means that the strand of linked blister packs is rolled up, for instance, or folded in a specific manner. In order that the occurrence of possible systematic error can be detected, it is essential for the invention that the optical detection device is disposed between the packaging station and the storage station.

As already stated, systematic errors (application of data in the case of the wrong location, "unreadable" application of data) can occur during the blistering process or during the production of the strand associated with the blisters. If a systematic error occurs, it may be appropriate to stop the apparatus to avoid producing a large number of flawed blister packs. Flowever, if there is only one pack-related error, it is usually not advisable to stop the apparatus. To make it easier for a user to recognize a faulty blister pack, it is provided in a preferred embodiment of the apparatus according to the invention that this comprises a marking device disposed between the optical detection device and the storage station and coupled to the control device, with which individual blister packs recognized as flawed can be marked. For instance, it is conceivable simply to provide a faulty blister pack with a striking colour marking.

The task is further solved by a method according to claim 3. In the method for operating the apparatus for packaging individual medicament portions, the control device is first provided with order data, wherein these order data relate to medicament compositions in each case with at least one medicament portion. From the storage and dispensing stations, based on the order data, portions of medication composition are dispensed and fed to the packaging station via at least one guiding and collecting arrangement. From the labelling or printing station, data are applied to the packaging material at predetermined application locations and subsequently a strand of connected blister packs is formed by the packaging station from the provided packaging material with the applied data, wherein data are assigned to each blister pack, i.e. the blister packs are formed such that each previously applied data are disposed. When forming the blister pack, the dispensed medication compositions are introduced into the blister pack.

The strand of blister packs produced in this way is fed to an optical detection device, and with this, the data applied to the blister packs are optically detected and the recorded data for a blister pack is compared with desired features. When a deviation between the acquired data and the desired features is determined, a response associated with the deviation is triggered.

Finally, the strand of blister packs leaving the optical detection device is stored, i.e. orderly stored (for instance, on a roll).

With the help of the method according to the invention, it is possible to detect (systematic) errors when applying the data to the packaging material. The optical detection device, which, for instance, may comprise a camera, detects predetermined features of the applied data. In the simplest case, for instance, this may merely be the point of application of the data. In case under correct operation of the labelling and printing station, the data are applied exactly centred on the blister packs (and thus on an appropriate location of the packaging material) and with the optical detection device it is determined that the data is disposed too far "outwards" on the blister packs, then in response to, for instance, five consecutive flawed blister packs, the apparatus may be stopped. In this manner, it is avoided that a large number of flawed blister packs is generated.

Which reaction is triggered depends on the type and frequency of the deviations determined. When, after a misprint of data, again, for instance, more than five blister packs are printed without errors, the operation of the apparatus can be maintained despite the misprint. With the method according to the invention in its above-described form, systematic errors in the application of the data can be detected and the apparatus can be stopped, if necessary, so that the production of a large number of flawed blister packs, which could possibly be produced anew, can be avoided.

In order to be able to respond to errors in the medication composition in a blister pack, the desired features can be derived from the order data, whereby the desired features additionally include information about, for instance, the number of individual portions of medication in a blister pack.

In the optical detection of the features of a blister pack, not only the application position of the data on the blister pack is determined, but also, for instance, the number of individual portions of medication is determined. If it is determined that although the application of the data on the blister pack is flawless, but a number of medication portions introduced in the blister pack does not match the desired features, the blister pack can be marked as flawed in such a pack-related deviation.

In a preferred embodiment, furthermore, the order data associated with the flawed blister pack are marked as flawed to facilitate, for instance, later finding of the flawed blister pack in the strand of blister packs. Alternatively, or additionally, the order data of a flawed blister pack are provided for reprocessing, so that it is possible without intervention of a user, despite a first erroneous compilation to produce a blister pack whose medication composition corresponds to the order data.

In the following, two preferred embodiments of the apparatus according to the invention and a preferred embodiment of the method according to the invention are described with reference to the accompanying drawing, in which

Figure 1 shows a schematic perspective view of a first embodiment of the apparatus according to the invention;

Figure 2 shows a schematic side view of a second embodiment of the method according to the invention; and

Figure 3 shows a detailed view of the section of the apparatus before the actual production of the blister packs.

Figure 1 shows a first embodiment of the apparatus 1 according to the invention, wherein in this illustration only the features that are essential for the invention are illustrated. Insignificant structural features such as the outer wall, display and input means, etc. have been omitted for the sake of simplicity.

The apparatus according to the invention comprises a support structure and/or frame 4 on which a plurality of storage and dispensing stations 2 are detachably fastened, wherein a specific type of medication portions can be arranged in each storage and dispensing station 2. Usually, 2 different portions of medication are disposed in each storage and dispensing station. In the case of such portions of medication, which are frequently requested, however, it is also possible for the same portions of medication to be stored in several storage and dispensing stations 2.

The storage and dispensing stations 2 in the embodiment shown are disposed in two opposite matrix structures 5 (of which only a matrix structure is shown), wherein the matrix structures 5 include two first horizontal conveyor belts 6a, 6b to which guide means 7 are attached. The guide means are detachably secured by fasteners 8, which are part of the two first conveyor belts 6a, and 6b.

In the embodiment shown, only a few guide means 7 are shown; in practice, a guide means 7 is fastened regularly to each fastening element 8, so that the two first conveyor belts 6a, 6b are completely provided with conveying devices.

In the embodiment shown, the guide means are movable over the first conveyor belts along the storage and dispensing stations 2. As a result, parallel processing of order data is made possible, since a guide means moves past every available portion of medication and thus with each guide means a medication composition can be processed. However, a corresponding embodiment of the guide means is not essential for the present invention. For instance, only a single guide means can be provided, which can receive portions of medication from all available storage and dispensing stations.

The conveyor belts 6a, 6b are driven by drive rollers 12, which are coupled via a vertical shaft 10 with a motor 11. In order to prevent slippage of the first conveyor belts 6a, 6b in the case of the drive rollers 12, they are advantageously provided with surface contouring.

To accommodate portions of medication of all storage and dispensing stations 2, the guide means 7 has a plurality of (not shown) openings. In order to reduce the drop height of individual portions of medication in the guide means 7, they have a plurality of undercuts 14 in the embodiment shown, which are each associated with a horizontal row of storage and dispensing stations.

The apparatus further comprises a second conveyor belt 15, which is disposed below the two first conveyor belts, and which likewise has a plurality of fastening elements 16. In each case, a collecting means 17 is fastened to the fastening elements in which medication compositions are temporarily stored before transferring them to a packaging station 3. The second conveyor belt 15 is also coupled via a gear wheel and the vertical shaft 10 to the motor 11, so that the guide means 7 and the collecting means 17 are moved at the same rotational speed. As can be seen in particular in Figure 1, however, the matrix of the storage and dispensing stations as well as the first two conveyor belts 6a, 6b do not extend over the entire length of the conveyor belt 15, but, in view of the "length" of the apparatus, it is kept shorter, so that at a certain point within the apparatus, a separation between the guide means and the collecting means takes place. The guide and collecting devices (which together form the guide and collecting arrangement) move synchronously in the area of the storage and dispensing stations in the depicted embodiment, separation takes place at the end of the matrix structure of the storage and dispensing stations. However, such an embodiment is not essential for the invention. In another, much simpler embodiment of the apparatus according to the invention, it is conceivable that the apparatus has several (or even only one) combined guide and collecting arrangement, by means of which medication compositions are guided to the packaging station 3.

In the embodiments shown in Figures 1 and 2, the collected medication compositions are fed to the packaging station 3 by means of the plurality of movable collecting means 17. With reference to Figure 3, the packaging station and components upstream of the packaging station of the two embodiments of the apparatus according to the invention are described below. A supply roll 32 with packaging material 34 is assigned to the packaging station 3. The supply roll 32 itself is moved by a drive 33. The packaging material 34 is guided to or through a labelling or printing station 20 (not visible in Figure 3) coupled to the control device 80 for applying data predetermined by the control device in a predetermined order onto the packaging material 34. How accurately the given data is applied to the packaging material depends on the particular embodiment. For instance, it is conceivable that the data is printed on the packaging material 34, or that a label with the predetermined data is glued to the packaging material.

The packaging material 34 leaves the labelling or printing station 20 with applied data 52, wherein the data is applied to the packaging material 34 in such a way that the data for each blister pack to be formed subsequently is likewise at a predetermined position. By means of two guide rollers 35, the packaging material provided with data is fed to a forming area of the packaging station 3, in which the packaging material is folded centrally to a V-shape into which the medication compositions can be introduced upon opening of collecting means 17.

The packaging material 34 is provided with one longitudinally and two transversely extending seals, wherein through these seals self-contained blister packs are produced. These are not separated from each other after completion, but they form a strand 50 with connected blister packs 51.

For producing the longitudinal seal, two heating means 37 are provided, of which only one is depicted in Figure 3. These two heating means press together the two upper ends of the V-shaped folded packaging material and weld them together. The transverse seals of the blister bag are made by two rotating heating means 39, the rotation of which is fine-tuned with each other. Based on the speed of movement of the packaging material 34 and the rotational speed of the heating means 39, the length, and thus the capacity, of the blister pack can be controlled precisely.

In a sealing or production of the blister pack with the heating means, a corresponding packaging material 34 is to be selected. In alternative embodiments, it is possible to produce the individual blister packs in other ways, in which case the packaging material is to be adapted accordingly. Thus, for instance, it is also possible to apply a sealing or adhesive material during the manufacture of the blister pack, by means such adhesive effect is the blister pack produced.

As can be seen in Figures 1 and 2, the strand 50 with connected blister packs 51 is guided out of the packaging station 3 to an optical detection device 40 disposed downstream of the packaging station 3 and coupled to the control device 80. This optical detection device comprises at least one detection means 41, which may be, for instance, a camera. By means of this detection means 41, data of the blister pack passing through the detection device is detected. In the simplest case, for instance, it is only detected at which point the data previously applied to the blister pack with the labelling or printing device are disposed, or whether any (readable) data are disposed on the blister packs.

These "data" of a blister pack passing through the optical detection device are compared with desired features of the respective blister pack by an evaluation device 90 coupled to the control device 80 (the two aforementioned devices are only shown in Figure 1 but are also present in the embodiment according to Figure 2). Referring to the simplest embodiment described above, for instance, it is compared or determined whether the applied data was applied to the blister packs at the right or at the prescribed point.

Since the data is usually applied in a machine-readable form (for instance in the form of a bar code), it is essential that these are applied in such a way that they can be read by a machine. For this purpose, it is necessary for the data to be arranged on the blister pack in a specific detection range of a machine reading out this data. If it is determined in the aforementioned comparison that this is not the case, then the first blister pack on which this error was determined initially has a pack-specific error. To make this also visually visible on the blister pack, the embodiment of the apparatus according to the invention shown in Figure 2 comprises a marking apparatus 70, by means of which the blister pack recognized as flawed is optically marked by at least one marking means 71, 72, for instance, by marking the pack with an optical highlighted colour.

If the same or similar errors are detected on the blister pack(s) following the first flawed blister pack, the operation of the apparatus is stopped in response to the detected deviations in order to minimise the number of flawed blister packs. After exactly how many and which deviations the apparatus is stopped depends on parameters that can be specified on the control device or on the evaluation device.

In the case that the desired features are derived from the data specified in the order, such also include "features" with regard to the medication composition contained in a blister pack. For instance, the desired features include information about how many portions of medication comprises a medication composition. In such a case, the optical detection device, optionally with an additional detection means 42, determines how many portions of medication are disposed in a blister pack, and this number is compared with the corresponding desired feature. If it is determined that there is a difference in the number of portions of medication, this blister pack is marked as flawed. As already stated, the blister pack can be optically marked for this, but it is also possible (additionally) to mark the order data as flawed or to designate this order data for rework, to ensure that after all the order data have been processed also the order data were processed by which error occurred in the first composition.

After the strand 50 has passed through the optical detection device, this is stored in the magazine on a roller 62 that is driven by a motor 61. In alternative embodiments, for instance, the strand may also be stored in an orderly folded manner.
