Abstract
Description
- The present invention concerns an electronic drug packaging for improved compliance.
- Electronic drug packagings for improving an adherence to a prescribed dosage pattern of a medication are known per se. These packagings often suffer from being complicated to use. This makes the packaging less suitable for certain groups of people. Other packagings suffer from being too fragile, unable to withstand daily use.
- In general it is desirable to improve adherence to a prescribed dosage pattern of a medication. It is also desirable to provide a system that can be used at low costs. It is also desirable to provide a system that is rugged.
- According to the invention is provided a packaging system for medicaments. The system includes an exchangeable blister pack including a plurality of pockets for each housing a unit of medicament. The system further includes a processing unit. The blister pack includes a first electric circuit that is wiredly connected to the processing unit. The blister pack includes a second electric circuit that is wirelessly connected to the processing unit. The processing unit is arranged for wirelessly retrieving information representative of a prescribed dosage pattern of the units from the second electric circuit. The processing unit is arranged for wiredly retrieving information representative of actual taking of a unit from the blister pack from the first electric circuit.
- The exchangeable blister pack can contain a plurality of units of a medicament, such as pills, tablets capsules or the like. The exchangeable blister pack can be a single use packaging that is to be discarded after taking all of the units initially included in the blister pack. It will be appreciated that the exchangeable blister pack of the system can be replaced by another, e.g. full, blister pack e.g. after depletion of the former blister pack. The exchangeable blister pack can include a first sheet, e.g. a plastic sheet, including the plurality of pockets for holding the units. The exchangeable blister pack can include a second sheet, e.g. an aluminum sheet or laminate sheet, closing the pockets. The second sheet is breakable so as to allow removal of the units from the pockets.
- Optionally, the second sheet includes the first electric circuit. The first electric circuit can include a plurality of switches, each pocket of the first sheet having a switch of the plurality of switches associated therewith, such that removal of a unit from its pocket opens the associated switch. The processing unit then can be wiredly connected to the switches, the processing unit being arranged for determining opening of a switch. A switch may include a frangible electric conductor. Opening of the switch may include breaking of the frangible electric conductor. The opening of a switch is representative of an actual taking of a unit from the blister pack.
- The second electric circuit can include a memory storing the information representative of the prescribed dosage pattern of the units. The prescribed dosage pattern can e.g. include prescribed intervals between the taking of a unit of the medicament. Alternatively, or additionally, the prescribed dosage pattern can include prescribed moments, such as prescribed clock times, for the prescribed taking of a unit of the medicament. The information representative of the prescribed dosage pattern can include timing data, such as intervals or moments. Alternatively, or additionally, the information representative of the prescribed dosage pattern can include a code, the code being representative of the dosage pattern. The code can be recognized by the processing unit and linked to an actual dosage pattern. A plurality of codes and associated dosage patterns may be stored in a memory associated with the processing unit. The second electric circuit can include a communication section, such as an antenna for communicating the information to the processing unit. The second electric circuit can e.g. be arranged to communicate through radio frequency identification (RFID), e.g. according to ISO/IEC 18000-3, and/or near field communication (NFC), e.g. according to ISO/IEC 18092, ECMA-340, ISO/IEC 21481 and/or ECMA-352. The second electric circuit can include an, unpowered, NFC chip, sometimes also referred to as a tag.
- The processing unit being arranged for both wiredly and wirelessly retrieving information from the blister pack provides several advantages. The wiredly retrieving of information representative of actual taking of a unit from the blister pack allows for cheap and robust retrieval of information. Also, as this retrieval of information is performed wiredly it ensures physical connection between the blister pack and the processing unit. This may prevent tampering or misreading of information. The wirelessly retrieving of information representative of a prescribed dosage pattern of the units allows for retrieval of complex information without the need for a complex physical interface between the blister pack and the processing unit. This too may prevent misreading of the information and/or reduce the risk of malfunction. Also current wireless information retrieval technologies, such as for example NFC, allow for cheap storage and retrieval of information, which is of great importance if the blister pack is to be a disposable.
- Optionally, each pocket of the plurality of pockets has a switch of the plurality of switches associated therewith, such that removal of a unit from its pocket opens the associated switch, wherein each switch has an electrical resistance. Optionally the switches are electrically connected in parallel and the blister pack includes a first contact electrically conductively connected to a first sides of the switches and a second contact electrically conductively connected to a second side of the switches. This allows for a very simple wired interface between the processing unit and the first and second contacts of the blister pack. The opening of a switch results in a change of the resistance of the first electric circuit between the first and second contacts. The processing unit can be arranged to detect a change in resistance between the first and second contacts.
- It is also possible that the first sheet includes more than one pluralities of pockets. The first electric circuit can then include a first plurality of switches electrically connected in parallel, and a second plurality of switches electrically connected in parallel, each plurality of parallel switches being arranged for wired connection to the processing unit. The blister pack can include a plurality of pluralities of pockets, the first electric circuit including a plurality of pluralities of switches, wherein the switches within each plurality of switches are electrically connected in parallel.
- Optionally, each switch has a different resistance. Optionally within each plurality of switches each switch has a different resistance. Then the opening of an individual switch has a different effect on the effective resistance of the first electric circuit between the first and second contacts than the opening of an other switch. The processing unit can be arranged for determining which switches of the plurality of switches are open on the basis of the determined electric resistance.
- Optionally, the processing unit includes a memory arranged for storing the information representative of actual taking of a unit from the blister pack.
- Optionally the processing unit includes a clock, such as a real time clock. The processing unit can be arranged for storing an indication of time, such as a timestamp, at which a unit was taken from the blister pack.
- Optionally, the processing unit includes an alarm unit arranged for, according to the prescribed dosage pattern, indicating to a user that a unit of medicament has to be taken. The alarm unit can for instance be a buzzer, a loudspeaker or a light source.
- Optionally, the processing unit is arranged to determine an alternative dosage pattern on the basis of the prescribed dosage pattern and on the basis of a time of an actual taking of a unit of medication. For instance, if a unit of medication has been taken too late, it may be desirable that the processing unit can calculate a suitable delay time for the next unit. It is possible that information relating to allowability of an alternative dosage pattern and/or relating to the alternative dosage pattern is stored in the memory of the second electric circuit.
- Optionally, the processing unit includes a communications unit arranged for communicating with an external data processor. The communications unit can include a physical connector, such as a USB connector, for wiredly connecting the processing unit to the external data processor, such as a personal computer. Alternatively, or additionally, the communications unit can be arranged for wirelessly communicating with the external data processor, such as via Bluetooth, Wifi, Zigbee or the like. The processing unit can e.g. communicate the information representative of the actual taking of a unit of medicament from the blister pack to the external data processor. Then a reviewer, such as a medical professional, can review adherence to the prescribed dosage pattern.
- Optionally, the packaging system further includes a housing arranged for housing the blister pack when wiredly and wirelessly connected to the processing unit. The housing can e.g. be substantially rigid. The housing can be dimensioned such that the blister pack is housed entirely within the housing. The housing can protect the blister pack from damage.
- Optionally, the housing includes a cover movable between an opened state allowing taking of a unit and a closed state preventing taking of a unit. Thus, easy access to the blister pack can be provided. Optionally, the housing is provided with a lock, such as a child-safe and/or senior-friendly lock. Optionally, the system further includes a switch arranged for switching the processing unit in a power save mode when the cover is in the closed state.
- The invention also relates to a blister pack including a first sheet including a plurality of pockets for each housing a unit of medicament and a second sheet closing the pockets, the second sheet being breakable for removing the units from the pockets. The second sheet includes a first electric circuit including a plurality of switches. Each pocket of the first sheet has a switch of the plurality of switches associated therewith, such that removal of a unit from its pocket opens the associated switch. The switches are electrically conductively connected to one or more contacts. The contacts can be wiredly connected to a processing unit. Optionally the switches are electrically connected in parallel. The blister pack may include a first contact electrically conductively connected to a first sides of the switches and a second contact electrically conductively connected to a second side of the switches. Optionally, each switch has a different resistance.
- Optionally, the blister pack includes a second electric circuit including a wireless communication circuit including a memory storing information associated with the units. Optionally the wireless communication circuit is a passive wireless communication circuit, such as a near field communication circuit.
- The invention also relates to a method for improving medicament intake. The method includes providing an exchangeable blister pack including a plurality of pockets each housing a unit of medicament, and a processing unit. The blister pack includes a first electric circuit that is wiredly connected to the processing unit. The blister pack includes a second electric circuit that is wirelessly connected to the processing unit. The processing unit is arranged for wirelessly retrieving information representative of a prescribed dosage pattern of the units from the second electric circuit, and for wiredly retrieving information representative of actual taking of a unit from the blister pack from the first electric circuit. The method further includes providing an indication that a unit of medication needs to be taken, on the basis of the information representative of the prescribed dosage pattern and the information representative of the actual taking of a unit of medication.
- Optionally, the method further includes determining an alternative dosage pattern on the basis of the prescribed dosage pattern and on the basis of a time of an actual taking of a unit of medication.

Figure 1 shows a schematic representation of an example of apackaging system 1 according to the invention. Thesystem 1 includes anexchangeable blister pack 2. Thesystem 1 further includes aprocessing unit 4. Thesystem 1 further includes ahousing 5. - The
exchangeable blister pack 2 includes afirst sheet 6 and asecond sheet 8. Thefirst sheet 6 includes plurality ofpockets 10 each holding apill 12, also seeFigures 2 and3 . In this example the first sheet is a plastic sheet. Thesecond sheet 8 closes thepockets 10. Thesecond sheet 8 is arranged to easily break when apill 12 is pushed from the side of thepocket 10, so as to allow easy removal of apill 12 from itspocket 10. - In this example the
exchangeable blister pack 2 is a single use packaging that is to be discarded after allpills 12 have been taken from theirpockets 10. It will be appreciated that theexchangeable blister pack 2 of thesystem 1 can be replaced by anotherexchangeable blister pack 2. Theprocessing unit 4 and thehousing 5 in this example is re-usable by refilling with anotherblister pack 2. - In this example the
second sheet 8 includes an electrically non-conducting sheet 8a, such as a paper sheet. The electrically non-conducting sheet 8a may be laminated to an electrically conducting sheet 8b, such as an aluminium foil. - The
second sheet 8 further includes a firstelectric circuit 14, seeFigures 4 and10 . The firstelectric circuit 14 may be included in or on the nonconducting sheet 8a, or onfurther sheet 8c. The firstelectric circuit 14 includes a plurality of switches 16. In this example the first electric circuit includes three groups 17.i (i=1, 2, 3) of switches 16. In this example the switch 16 includes a frangible electric conductor 18 overlying thepocket 10 holding thepill 12. It will be appreciated that expelling thepill 12 from itspocket 10 results in opening of the switch 16 by breaking of the frangible electric conductor 18. It is noted that eachpocket 10 of theblister pack 2 has its own switch 16. In this example each switch 16 has a predeterminedelectrical resistance 19. In the examples ofFigures 4, 5 and7 the resistance of each switch 16 is 5.1 kOhms. - It will be appreciated that, alternatively, within each group 17.i the
electrical resistance 19 of each switch 16 differs from the electrical resistances of the other switches of the group. For example, the resistors of a group can have values close to or equal to, 5100, 2550, 1700, 1275, 1020, 850, 728.57, and 637.5 Ohms, respectively. When each switch of a group has a different resistance, The effective resistance of the group can be made to be unique for each combination of opened switches. Then, it can be determined from the measured voltage (or measured resistance) which switches are opened and which switches are closed, i.e. which pockets contain a pill, and which pockets are empty. - In each group 17.i the switches 16 are connected in parallel by first and second tracks 20.i, 22.i. The first track 20.i electrically conductively connects first sides of the switches 16 to a first contact 24.i. The second track 22.i electrically conductively connects second sides of the switches 16 to a second contact 26.i. The first and second contacts 24.i, 26.i form part of a
blister pack connector 27. In this example the first and second tracks 20.i, 22.i are optimized to have minimum track length. It will be appreciated that the second contact 26.i of the all groups 17.i in this example is a common contact. - In this example the first
electric circuit 14 is printed on anon-conducting sheet 8c using conductive ink. Silver ink is used to print the tracks 20.i, 22.i and conductors 18 in this example. Carbon ink is used to printresistors 19 in this example. A coat oflamination 21 is used to block UV rays and moisture from coming into contact with the firstelectric circuit 14. Thenon-conducting sheet 8c may be attached to the first sheet to close 6 the pockets. Alternatively thenon-conducting sheet 8c may be attached to a sheet 8a or 8b already closing the pockets. The firstelectric circuit 14 may be printed on thenon-conducting sheet 8c prior to attaching the non-conducting sheet. - The
blister pack 2 further includes a secondelectric circuit 28. The secondelectric circuit 28 includes amemory 30. In this example thememory 30 stores information representative of a prescribed dosage pattern of thepills 12. In this example information representative of the prescribed dosage pattern includes information representative of prescribed intervals between the taking of a pill, such as eight hours between pills. Alternatively the information representative of prescribed dosage pattern can include information representative of prescribed moments, such as prescribed clock times, for the prescribed taking of a pill, such as 7:00 AM. - The second
electric circuit 28 includes acommunication section 32. In this example the communication section is anantenna 34 for communicating with an interrogating electric field, e.g. at a frequency of 13.56 MHz. In this example the secondelectric circuit 28 is arranged to communicate over near field communication, NFC, e.g. according to ISO/IEC 18092, ECMA-340, ISO/IEC 21481 and/or ECMA-352. In this example the secondelectric circuit 28 is included in a tag 29, e.g. a sticker, attached to theblister pack 2. - In this example both the first
electric circuit 14 and the secondelectric circuit 28 are passive circuits. Therefore, there is no need for a power source in theblister pack 2. - The
processing unit 4 includes aprocessing unit connector 31, seeFigures 5 ,6 and7 . Theprocessing unit connector 31 is arranged to mate with theblister pack connector 27. In this example theprocessing unit connector 31 includes aslot 32 for insertion of a side area of the blister pack. The processing unit connector includes third contacts 34.i and fourth contacts 36.i. The third contacts 34.i form a wired connection to the first contacts 24.i of the firstelectric circuit 14. The fourth contacts 36.i form a wired connection to the second contacts 26.i of the firstelectric circuit 14. - The
processing unit 4 includes aprocessor 38. Theprocessor 38 is arranged for determining a resistance of the firstelectric circuit 14. Thereto theprocessor 38 is arranged for measuring the electrical resistance between the third and fourth contacts 34.i, 36.i. Ameasurement unit 39 of theprocessor 38, here an analog-to-digital converter, ADC, may thereto be arranged to determine a voltage difference between the third and fourth contacts 34.i, 36.i when a current is known. In this example theprocessing unit 4 includes resistors 40.i connected between the third and fourth contacts 34.i, 36.i. Therefore, when all switches 16 of theblister pack 2 are opened, theprocessor 38 measures a resistance between the third and fourth contacts equal to the resistance of the resistor 40. When one or more switches are closed theprocessor 38 can determine whether one or more switches are opened and which one or more switches are opened, based on the measured resistance and based on the predetermined different electrical resistances of the switches 16. - The
processing unit 4 includes aclock 42, such as a real time clock. Theprocessing unit 4 includes amemory 44. In this example the processing unit is arranged for storing in thememory 44 an indication of time, such as a timestamp, at which apill 12 was taken from itspocket 10. - The
processing unit 4 includes a wirelessinformation retrieval unit 46. In this example the wirelessinformation retrieval unit 46 is a near field communication unit arranged for arranged near field communication, NFC, e.g. according to ISO/IEC 18092, ECMA-340, ISO/IEC 21481 and/or ECMA-352. The wirelessinformation retrieval unit 46 is arranged for interrogating the secondelectric circuit 28. The wireless information retrieval unit is arranged for retrieving information stored in thememory 30 of the secondelectric circuit 28. In this example the wirelessinformation retrieval unit 42 is arranged for retrieving information representative of the prescribed dosage pattern of thepills 12. It will be appreciated that thememory 30 can also store other information such as the predetermined different electrical resistances of the switches 16, information relating to the manufacturer of the blister pack and/or of the medication, an expiry date, etc. All such information can also be retrieved by the wirelessinformation retrieval unit 46. The information retrieved by the wireless information retrieval unit can be stored in thememory 44 of theprocessing unit 4. - In this example the
processing unit 4 includes an alarm unit 48. Theprocessing unit 4 is arranged for activating the alarm unit 48 for indicating to a user that apill 12 has to be taken from theblister pack 2. Theprocessing unit 4 can activate the alarm unit 48 according to the prescribed dosage pattern as retrieved from the secondelectric circuit 28. In this example the alarm unit 48 includes aloudspeaker 50 and alight source 52. Theprocessing unit 4 can also be arranged to activate the alarm unit when theblister pack 2 included in thehousing 5 is depleted. Optionally the alarm unit 48 thereto includes a separate, secondlight source 53. - In this example the
housing 5 houses both theblister pack 2 and theprocessing unit 4. As can be seen fromFigure 1 , theblister pack 2 is housed entirely within thehousing 5. In this example the housing is rigid, e.g. manufactured from plastic. - In this example the
housing 5 includes a tray 5a in which theblister pack 2 is mainly housed. The tray 5a can includefirst grooves 56 into which theblister pack 2 can be slidingly inserted. Thehousing 5 includes ahead 5b, 5c in which theprocessing unit 4 is housed. The shells of thehead 5b, 5c may be interconnected, e.g. through fasteners 5e Thehead 5b, 5c connects to the tray 5a. In this example thehead 5b, 5c snap-fits to the tray 5a. Here thehousing 5 further includes ablister lock 5d which locks theblister pack 2 to thehead 5b, 5c, so that theblister pack connector 27 remains connected to theprocessing unit connector 31. - The
housing 5 also includes acover 58. Thecover 58 is slidingly held insecond grooves 60, seeFigure 3 . Thecover 58 can be slid from an opened state allowing taking of apill 12 to a closed state preventing taking of apill 12, and vice versa. In this example, thecover 58 includes anupper cover part 58a and a lower cover part 58b. Hence, the cover can be slid from an closed state to a partially opened state to a fully opened state, seefigure 2 . - The
housing 5 is provided with alock 62, seeFigures 8A and 8B . In this example thelock 62 includes alip 64 that can be hooked in arecess 66. The cover further includes ahook 65 arranged for preventing thecover 58 to be detached from the body of thehousing 5. In this example, therecess 66 is positioned in a movable stopper 66a. The movable stopper 66a is biased towards a position in which therecess 66 grips thelip 64, seeFigure 8A . If the movable stopper 66a is pressed against the biasing force of abiasing element 66b at atip 66b projecting through thehead part 5b, therecess 66 is moved to release the lip, seefigure 8B . Then thecover 58a, 58b can be slid aside to access thepockets 10. - The
cover 58 further includes a grippingarea 67 having a surface structure enabling easy sliding of the cover by the use of a finger or thumb. - In this example the
cover 58 is transparent to allow visual inspection of theblister pack 2 without necessitating to open the cover. In this example thehousing 5 includes a support structure 69 underneath theblister pack 2. The support structure 69 includes a plurality of opening 71 for allowing the taking of thepills 12. - In another example, see
Figure 12 , theprocessing unit 4 includes fourbuttons 54. It will be appreciated that in general one ormore buttons 54 can be included. The buttons are connected to theprocessor 38. In this example each button is associated with a predetermined symptom, such as drowsy, nauseous, headache, neutral, feeling cold, feeling hot, feeling better, or the like. When abutton 54 is pressed, theprocessing unit 4 stores information representative of the associated symptom, preferably together with a timestamp representative of the moment of pressing thebutton 54. - In this example the
housing 5 houses both theblister pack 2 and theprocessing unit 4. As can be seen fromFigure 12 , theblister pack 2 is housed entirely within thehousing 5. In this example the housing is rigid, e.g. manufactured from plastic. In this example the housing includesfirst grooves 56 into which theblister pack 2 can be slidingly inserted. The housing also includes aretainer 57 for preventing theblister pack 2 from unintentionally being expelled from thehousing 5. In this example, the retainer includesgrips 59 for allowing to exert enough force to remove theretainer 57 by hand. - The
housing 5 also includes acover 58. Thecover 58 is slidingly held insecond grooves 60. Thecover 58 can be slid from an opened state allowing taking of apill 12 to a closed state preventing taking of apill 12, and vice versa. Thehousing 5 is provided with alock 62. In this example thelock 62 includes alip 64 that can be hooked in arecess 66. The cover further includes ahook 65 arranged for preventing thecover 58 to be detached from the body of thehousing 5. Thecover 58 further includes a grippingarea 67 having a surface structure enabling easy sliding of the cover by the use of a finger or thumb. - The
system 1 further includes aswitch 68 arranged for switching theprocessing unit 4 in a power save mode when thecover 58 is in the closed state. In this example thecover 58 is transparent to allow visual inspection of theblister pack 2 without necessitating to open the cover. In this example thehousing 5 includes a support structure 69 underneath theblister pack 2. The support structure 69 includes a plurality of opening 71 for allowing the taking of thepills 12. - In the examples the
processing unit 4 further includes aconnector 70, such as a USB connector, miniUSB connector, or microUSB connector. Theconnector 70 allows for wiredly connecting theprocessing unit 4 to an external data processor, such as a personal computer. Alternatively, or additionally, the processing unit can include awireless communications unit 72 arranged for wirelessly communicating with the external data processor, such as via Bluetooth, Wifi, Zigbee or the like. Theprocessing unit 4 can e.g. communicate the information representative of the actual taking of apill 12 from theblister pack 2 to the external data processor. The processing unit can also communicate additional data to the external data processor, such as data related to events of pressing abutton 54. Then a reviewer, such as a medical professional, can review adherence to the prescribed dosage pattern and other data. The processing unit also includes abattery 55, such as a 3.3V battery. In this example, the battery is rechargeable through theconnector 70. - The
packaging system 1 according to the invention can be used as follows. - A patient visits his or her doctor in event of illness. The doctor prescribes a medication. In order for the medication to have maximum effect, proper adherence to a prescribed dosage pattern is important. The patient goes to the pharmacist to obtain the medication. The pharmacist provides the medication, wherein units of the medication (such as pills, tablets or capsules) are included in a
blister pack 2 as described above. Theblister pack 2 has the near field communication, NFC,circuit 28. Thecircuit 28 can be included in theblister pack 2 during packaging of the medication in the blister pack, e.g. at a factory. Alternatively, the pharmacist can apply the tag 29 including thecircuit 28 to theblister pack 2. The tag 29 can e.g. be a self-adhesive tag. TheNFC circuit 28 has inbuilt memory to store information related to the prescribed dosage pattern. For NFC circuit programming with dosage details, a computer based application can be used, this application can be used to transmit data to the NFC circuit through an NFC transceiver device connected to the computer. - The patient obtains, or already possesses, a
processing unit 4 as described above. The patient may e.g. obtain or possess an assembly including theprocessing unit 4 and thehousing 5 as described above. Theblister pack 2 is inserted into thehousing 5. Theblister pack 2 can e.g. be slid into thefirst grooves 56 of thehousing 5. Theblister pack connector 27 mates with theprocessing unit connector 31. Thereby the first contacts 24.i are brought in electrically conductive connection with the third contacts 34.i and the second contacts 26.i are brought in electrically conductive connection with the fourth contacts 36.i. Theblister pack 2 now is wiredly connected to theprocessing unit 4. Thehead 5b, 5c is connected to the tray 5a, or theretainer 57 is positioned to prevent inadvertent expulsion of theblister pack 2 from thehousing 5. - When the
blister pack 2 is inserted into thehousing 5 the wirelessinformation retrieval unit 46 reads information stored in thememory 30 of the secondelectric circuit 28. In this example theprocessor 38 retrieves the information representative of a prescribed dosage pattern of thepills 12 and stores it in thememory 44. Theprocessing unit 4 determines moments when apill 12 has to be taken on the basis of the prescribed dosage pattern. For example, the processing unit determines moments when apill 12 has to be taken on the basis of a timestamp of a taking of a first pill from the blister pack, and on the basis of a prescribed time interval in between two takings of a pill. For example the processing unit determines moments when a pill has to be taken on the basis of predetermined times defined in the prescribed dosage pattern, e.g. at 7:00 AM and at 5:00 PM. - After inserting the
blister pack 2 in thehousing 5 thecover 58 is closed. Putting thecover 58 in the closed state can bring thesystem 1 in sleep mode. In sleep mode circuitry of theprocessing unit 4 for retrieving information from the first and/or second electric circuit is disabled. In this example the system is re-activated only when the cover is opened. Nevertheless, in this example the alarm unit 48 and theoptional input buttons 54 are also functional in sleep mode. Thecover 58 also prevents false trigger and recording of medication administration. - When the
processing unit 4 determines that the time indicated by itsclock 42 corresponds to a moment when a pill has to be taken, theprocessing unit 4 activates the alarm unit 48. In this example, the alarm unit 48 includes anLED light source 52 and aloudspeaker 50. When activated the LED will flash green and the loudspeaker will generate a sound. Reminders through multiple modes, here both auditory and visual, ensures that the compliance adherence is maximized. - When reminded by the alarm unit 48 the patient opens the
cover 58. This may end the sleep mode and render thesystem 1 fully operational. The patient takes onepill 12 from itspocket 10 and administers thepill 12 as required. Taking the pill from itspocket 10 opens the associated switch 16. This is detected as a change in electrical resistance between the third and fourth contacts 34.i, 36.i by the processing unit. In this example theprocessing unit 4 polls an analog-to-digital converter, ADC, at predetermined time intervals, of e.g. 10 ms, to determine a change in voltage between the third and fourth contacts 34.i, 36.i. The processing unit stores the event of taking the pill and the time associated with it. In this example, from the electrical resistance measured between the third and fourth contacts 34.i, 36.i theprocessing unit 4 determines which switch 16 has been opened, viz. which pill has been taken. The processing unit also stores which pill has been taken with the event. - After the patient has taken the
pill 12, he or she closes thecover 58 again and the system goes into sleep mode again. When the next moment for taking a pill arises theprocessing unit 4 activates the alarm unit 48 again and the process is repeated. - After taking of the last pill of the blister pack, the processing unit may determine that the
blister pack 2 is depleted. The processing unit may then activate the alarm unit to indicate depletion, and required replenishment, of the blister pack to the patient. In this example the alarm unit 48 thereto activates the secondlight source 53. Alternatively, thefirst light source 52 may be activate to flash, e.g. red, to indicate depletion of the blister pack. - During the course of taking the medication, the patient may experience symptoms associated with the use of the medication. When the patient experiences such symptom, he or she can press the associated
button 54 on theprocessing unit 4. Theprocessing unit 4 then stores an event indicating the time and the symptom experienced. - After, or during, the medication, the patient carries the
system 1 to the physician in his or her next visit. The physician can inspect the medication history of patient by connecting thesystem 1 to his computer with theconnector 70 orwireless communications unit 72. The data stored in thememory 44 can be displayed, e.g. in the form of graphs or tables, on a graphical user interface. - The blister pack can be manufactured as follows.
- The
first sheet 6 including a plurality ofpockets 10 is provided. In each pocket 10 a unit of medication is placed. The pockets are closed with a sheet of aluminium foil 8b. The firstelectric circuit 14 is printed on a first side of an electricallynon-conductive sheet 8c, such as a paper sheet. Optionally, branding and labeling information is printed on the other side of the non-conducting sheet. The first side of thenon-conductive sheet 8c is provided with an adhesive layer. Thenon-conductive sheet 8c is adhered to the aluminium foil sheet 8b. Optionally a further non-conductive sheet 8a is interposed between thesheets 8b and 8c.

Thereto the second electric circuit may store additional data such as minimum time between takings of a unit of the medication, allowability of taking forgotten units of the medication, earliest allowable taking times, latest allowable taking times, etc.. The processing unit can retrieve such additional data from the second electric circuit. For example if a pill has to be taken daily at 8:00 AM, but the previous pill was not taken until 4:00 PM it might be advisable to postpone activating the alarm for the taking of the next pill until after 8:00 AM, e.g. until 11:30 AM.
