The invention relates to individualized compounds of medicines, in particular pills.The invention relates to individualized compounds or medicines, in particular pills.
For medicine users who use a plurality of different medicines, it is often difficult to ensure that at each intake moment, a prescribed combination of medicines is taken. In order to facilitate taking the prescribed combination at each intake moment, it has been proposed to prepare individualized compound doses of medicines, and to prepackage these doses according to subsequent intake moments for a particular patient.For medicine users who use a variety of different medicines, it is often difficult to ensure that each intake moment is a prescribed combination of medicines. In order to facilitate the prescribed combination at each intake moment, it has been proposed to prepare individualized compound doses of medicines, and to prepackage these doses according to subsequent intake moments for a particular patient.
In practice, for each of a series of subsequent intake moments, pills are collected from selected cassettes of a dispensing machine to form an individualized compound dose of medicine in accordance with a patient prescription record, and the doses are individually packaged in a string of sealed packages. In order to ensure the correctness of the compound doses, the composition of each sealed package in the string is assessed and checked in an automated process, e.g. in accordance to the International patent publication WO 2005/017814 in the name of the applicant.In practice, for each of a series or subsequent intake moments, pills are collected from selected cassettes or a dispensing machine to form an individualized compound dose of medicine in accordance with a patient prescription record, and the doses are individually packaged in a string or sealed packages. In order to ensure the correctness of the compound doses, the composition of each sealed package in the string is assessed and checked in an automated process, e.g. in accordance with the international patent publication WO 2005/017814 in the name of the applicant.
The International patent publication WO 2015/126254 also in the name of the applicant discloses a method and device for receiving and checking individualized doses of medicines, wherein a plurality of dispensed medicines forming an individualized compound dose of medicines are received for assessing the composition of the individualized compound dose of medicines through automated recognition of the received medicines, using an optical inspection technique. The individualized compound dose of medicines are discharged to be packaged or other than to be packaged depending on the outcome of a step of checking the assessed composition of medicines against a record for the composition of said medicines.The International patent publication WO 2015/126254 also in the name of the applicant discloses a method and device for receiving and checking individualized doses of medicines, a variety of dispensed medicines forming an individualized compound dose of medicines are received for assessing the composition of the individualized compound dose of medicines through automated recognition of the received medicines, using an optical inspection technique. The individualized compound dose of medicines are discharged to be packaged or other than to be packaged depending on the outcome of a step or checking the assessed composition of medicines against a record for the composition of said medicines.
It appears, in practice, that at some instants medicines can not be uniquely recognized via optical inspection, e.g. if medicines overlap or if look-alikes occur i.e. if the individualized compound dose of medicines includes one or more medicines that have the same or similar optical appearance, e.g. having the same shape and colour. Then, the checking process might be interrupted which is less desired from an economic point of view.It appears, in practice, that at some instants medicines can not be uniquely recognized via optical inspection, eg if medicines overlap or if look-alikes occur if the individualized compound dose of medicines includes one or more medicines that have the same or similar optical appearance, eg having the same shape and color.

For the purpose of optically inspecting an individualized compound dose of dispensed medicines 11, the packaging device 1 may comprise a camera 12 or other image recording device arranged for optically inspecting the dose of dispensed medicines 11. Preferably, as shown in Fig.For the purpose of optically inspecting an individualized compound dose of dispensed medicines 11, the packaging device 1 may include a camera 12 or other image recording device arranged for optically inspecting the dose of dispensed medicines 11. Preferably, as shown in Figs.
1, the packaging device 1 includes a wired communication line 8 interconnecting the camera 12 and the control device 5 so that the control device 5 may control operation of the camera 12 and may receive optical data that have been recorded by said camera 12. During operation, the communication line 8 may transmit command messages from the control device 5 to the camera 12, and optical data from the camera 12 to the control device 5. Alternatively, communication between the camera 12 and the control device 5 is arranged in another way, e.g. using wireless communication means. Further, the camera 12 may be controlled by another control device or may operate autonomously such that the control device 5 operates depending on a process performed by the camera 12 or by another unit of the packaging device 1.1, the packaging device 1 includes a wired communication line 8 interconnecting the camera 12 and the control device 5 so that the control device 5 may control operation of the camera 12 and may receive optical data that have been recorded by said camera 12. During operation , the communication line 8 may transmit command messages from the control device 5 to the camera 12, and optical data from the camera 12 to the control device 5. Alternatively, communication between the camera 12 and the control device 5 is arranged in another way, eg using wireless communication means. Further, the camera 12 may be controlled by another control device or may operate autonomously such that the control device 5 operates depending on a process performed by the camera 12 or by another unit of the packaging device 1.
During operation of the packaging device 1, the control device 5 periodically performs the inspecting step, the verifying step and the processing step mentioned above on a plurality of dispensed medicines that are subsequently provided at the receiving area 4. By performing these steps, the individualized compound dose of medicines can be evaluated so as to determine whether there is a one-to-one relationship between the medicines in the compound dose and the medicines listed in the record for the composition of the individualized compound dose of medicines reflecting a prescription of medicines for a patient to be taken at an intake moment.During operation of the packaging device 1, the control device 5 periodically performs the inspecting step, the verifying step and the processing step mentioned above on a various or dispensed medicines that are provided in the receiving area 4.

The inspecting step generally includes receiving optical data of the individualized compound dose of dispensed medicines 11 received at the receiving area 4. The optical data is generated by the camera 12 recording an image of the dose of dispensed medicines 11. The optical data can be rough image data or pre-processed image data, e.g. image data wherein noise has been suppressed.The inspecting step generally includes receiving optical data or the individualized compound dose or dispensed medicines 11 received at the receiving area 4. The optical data is generated by the camera 12 recording an image of the dose or dispensed medicines 11. The optical data can be rough image data or pre-processed image data, eg image data with noise has been suppressed.
The verifying step generally includes assessing a group of recognized medicines through automated recognition of the optically inspected medicines and comparing the record for the composition of the individualized compound dose of medicines with said group of recognized medicines, for defining a first subset of verified medicines in the record.The verifying step generally includes assessing a group of recognized medicines through automated recognition of the optically inspected medicines and comparing the record for the composition of the individualized compound dose of medicines with said group of recognized medicines, for defining a first subset of verified medicines in the record.
By automated recognition of the optically inspected medicines at least a group of the dispensed medicines in the individualized compound dose of medicines 11 can be recognized, e.g. based on size, shape, color, texture, markings and/or spectroscopy analysis of medicine ingredients. The recognition can be performed by pattern recognition or other vision control methods applied to said optical data received from the camera 12, and comparing pattern characteristics to image data stored in a database or library. The pattern recognition process may include analyzing the optical data to extract pill identifying characteristics of individual medicines in the compound dose of medicines. If the pattern characteristics of a medicine in the compound dose of medicines uniquely match to a certain degree with image data in the database or library associated with a known type of medicine, said medicine in the compound dose of medicines can be recognized as a medicine of said known type. In this manner at least a group of dispensed medicines in the compound dose of medicines might be identifiable. Remaining medicines that are not uniquely recognized by automated recognition will be verified in another way, as explained below using dispense data. Automated recognition may fail for several reasons, e.g. if medicines are not separate from each other in the image captured by the camera, e.g. due to overlap, or if the orientation of a medicine in the image does not correspond to image data of the medicine stored in the database or library. Further, different medicines can be indistinguishable from each other with respect to optical characteristics. As an example, pills may have a similar size, shape, color, texture, markings and/or spectroscopy characteristics.By automated recognition of optically inspected medicines at least a group of dispensed medicines in the individualized compound dose of medicines 11 can be recognized, e.g. based on size, shape, color, texture, markings and / or spectroscopy analysis of medicine ingredients. The recognition can be performed by pattern recognition or other vision control methods applied to said optical data received from the camera 12, and comparing pattern characteristics to image data stored in a database or library. The pattern recognition process may include analyzing the optical data to extract pill identifying characteristics or individual medicines in the compound dose of medicines. If the pattern characteristics of a medicine in the compound dose of medicines uniquely match to a certain degree with image data in the database or library associated with a known type of medicine, said medicine in the compound dose of medicines can be recognized as a medicine or said known type. In this way at least a group of dispensed medicines in the compound dose of medicines might be identifiable. Remaining medicines that are not uniquely recognized by automated recognition will be verified in another way, as explained below using dispense data. Automated recognition may fail for several reasons, eg if medicines are not separate from each other in the image captured by the camera, eg due to overlap, or if the orientation of a medicine does not correspond to image data of the medicine stored in the database or library. Further, different medicines can be individualized from each other with respect to optical characteristics. As an example, pills may have a similar size, shape, color, texture, markings and / or spectroscopy characteristics.
By comparing the record for the composition of the individualized compound dose of medicines with said group of recognized medicines, a first subset of verified medicines in the record can be defined, based on the outcome of the comparison process. The comparing step can be performed by subsequently comparing each medicine in the record with the group of recognized medicines. If a medicine in the record and a medicine from the group of recognized medicine are of the same type, i.e. if the comparing result is positive, said medicine in the record can be added to the first subset of positively verified medicines in the record, while the corresponding medicine from the group of recognized medicines can be virtually removed from the group of recognized medicines in order to avoid reduce a chance that a particular recognized medicine is matched twice with a medicine in the record, i.e. with two or more medicines in the record. If a medicine in the record can not be matched with a medicine in the group of recognized medicines, i.e. if the comparing result is negative, said medicine in the record can be added to a second subset of not yet identified medicines in the record. Then, the second subset of medicines includes all medicines in the record that failed in the step of comparing with the group of recognized medicines.By comparing the record for the composition of the individualized compound dose of medicines with said group of recognized medicines, a first subset of verified medicines in the record can be defined, based on the outcome of the comparison process. The comparing step can be performed by successively comparing each medicine in the record with the group of recognized medicines. If a medicine in the record and a medicine from the group of recognized medicine are of the same type, ie if the comparing result is positive, said medicine in the record can be added to the first subset of positively verified medicines in the record, while the corresponding medicine from the group of recognized medicines can be virtually removed from the group of recognized medicines in order to avoid a chance that a particular recognized medicine is matched twice with a medicine in the record, ie with two or more medicines in the record . If a medicine in the record cannot be matched with a medicine in the group of recognized medicines, i.e. if the comparing result is negative, said medicine in the record can be added to a second subset or not yet identified medicines in the record. Then, the second subset of medicines includes all medicines in the record that failed in the step of comparing with the group of recognized medicines.
After performing the comparing step, a first subset of verified medicines and a second subset of not yet verified medicines have been generated, the combination of the first and second subset composing the list of medicines in the record.After performing the comparing step, a first subset of verified medicines and a second subset of not yet verified medicines have been generated, the combination of the first and second subset composing the list of medicines in the record.
If the group of recognized medicines is not virtually empty, after performing the comparing step, at least one recognized medicine does not match with a medicine of the same type in the record. Then, it is concluded that the verifying step has a negative result because the individualized compound dose of dispensed medicines includes at least one medicine that is not listed in the record.If the group of recognized medicines is not virtually empty, after performing the comparing step, at least one recognized medicine does not match with a medicine of the same type in the record. Then, it is concluded that the verifying step has a negative result because the individualized compound dose or dispensed medicines includes at least one medicine that is not listed in the record.
Further, if the first subset of verified medicines includes all medicines in the record, the step of verifying step can be completed by concluding that all medicines of the record match with the optically inspected medicines and that the verifying step has a positive result. Then, the second subset is empty.Further, if the first subset of verified medicines includes all medicines in the record, the step of verifying step can be completed by concluding that all medicines or the record match with the optically inspected medicines and that the verifying step has a positive result.
