Description

  The present invention relates to a protective sheet and a protective sheet storage case, and more particularly, to a protective sheet such as a PTP sheet that hermetically seals stored items such as pharmaceuticals, and a protective sheet storage case that electronically monitors the usage status of stored items. .

  Conventionally, barcodes and IC tags have been used to check the type and distribution channel of pharmaceutical products. Recently, a law on pharmaceutical traceability was enforced. One of them is the revised Pharmaceutical Affairs Law that came into effect on April 1, 2005. In addition, awareness of management efficiency improvement of medical institutions is increasing. In the pharmaceutical industry, there is a growing need for operational efficiency and cost reduction. In this way, from the viewpoint of preventing medical errors, there is an increasing expectation for a technique for automatically collecting drug data without human intervention and a technique for automatically recognizing a drug.

  As a means for automatic recognition, there is a barcode already widely used in article management. As the barcode, a JAN code (Japanese Article Number) as shown in FIG. Printing can be performed at the same time as printing the outer box of the product, and numerical information can be obtained by scanning the barcode itself with a laser scanner or the like. This JAN code is often used in pharmaceutical manufacturer part numbers printed on the outer packaging of pharmaceutical products. JAN codes are available in 13-digit standard types and 8-digit shortened types. The contents are divided into JAN manufacturer code, product item code, and check digit. Of these, the JAN manufacturer code must be registered with the Code Center in the Distribution System Development Center.

  In order to further increase the amount of information and ensure traceability, the two-dimensional bar code shown in FIG. 3B and the EAN128 code shown in FIG. 3C have been used at distribution sites. On the other hand, printing on a small ampule label of a pharmaceutical has a limit in EAN128 and the like, and an RSS (Reduced Space Symbol) code shown in FIG. 3D is about to be used for the purpose of reducing the printing surface.

  Bar codes such as JAN codes and RSS codes can be displayed relatively easily on the outer packaging and labels of pharmaceuticals by printing. However, in order to read the information, as shown in FIG. 3 (e), the barcode reader is brought close to the object one by one and directly irradiated with a laser beam or recognized as an image by a CCD image sensor. It takes time and labor to read. Also, if the barcode is hidden or dirty, reading is impossible. In the first place, new data cannot be written in the barcode itself. Separately, a database system is prepared, and information is written at a predetermined position in the database using a numerical sequence indicated by the barcode as an ID code.

  In recent years, attempts to use contactless electronic tags have been made to compensate for the weaknesses of barcodes. FIG. 4 shows a general contactless electronic tag and a reader / writer antenna that reads and writes information by communicating with the contactless electronic tag. The non-contact electronic tag includes a semiconductor chip, a communication antenna connected to the semiconductor chip, and a tag sheet that forms a tag by sealing the semiconductor chip and the communication antenna. The non-contact electronic tag receives electric power by receiving an electromagnetic wave from a reader / writer antenna with a communication antenna. Information is written and read by driving the semiconductor chip with the electric power.

  The communication antenna has a coil shape as shown in FIG. There is a method of forming an antenna by winding a copper wire in a loop shape. There is also a method of forming an antenna by evaporating or printing an aluminum material or the like in a coil shape. There is also a method of forming a coil-shaped copper wire by etching on a printed circuit board similar to that used for an electronic circuit board. About a tag sheet, the material can be made into a thin paper-like thing, and it can be set as a seal-type tag by apply | coating an adhesive agent to one side. Further, it can be sealed with PET resin and molded into a hanging type plate-like tag. As shown in FIG. 4B, such a non-contact electronic tag is attached to an outer box or an inner bag or hung around the neck of a medicine bottle. Write traceability information such as where you moved from where. By reading a plurality of pieces of tag information in a certain amount during inventory, the inventory time can be shortened and accuracy is improved.

  PTP (Press Through Pack) sheets are the mainstream packaging materials for pharmaceutical capsules and tablets. PTP sheets are generally made by bonding an aluminum film to the back of a vacuum-formed plastic sheet. High moisture-proof effect and easy quality control. Moreover, it can be packaged compactly. It has many advantages and is widely used from prescription drugs in hospitals to general over-the-counter drugs. FIG. 5A is a view showing a conventional general PTP sheet. As the sheet, PVC (polyvinyl chloride), PP (polypropylene), or the like is used. The lid sheet is made of aluminum foil. As shown in FIG. 5C, by pushing the storage portion of the sheet storing the medicine with a finger, the medicine tears the lid sheet and is pushed out.

  For individual drugs encapsulated in such PTP sheets, barcodes and non-contact electronic devices exist in large quantities, including not only in the pharmacy department of hospitals but also regular medicines such as wards and operating rooms. It is impossible to attach tags individually, and inventory management is very difficult. Similarly, confirmation of whether or not the medicine is actually taken in a hospital room can be confirmed only by a check by a nurse, and requires a lot of labor for the confirmation work. In order to prevent accidental ingestion, as shown in FIG. 5 (d), as shown in FIG. 5 (d), the medicines to be taken at a predetermined time are collected and encapsulated in a protective sheet similar to the PTP sheet. Jigs that take out and take only medicines to drink are also becoming popular. This can be determined only by visual inspection as to whether or not it was drunk. The following are some examples of prior art related to pharmaceutical traceability.

  The “tagged pharmaceutical package” disclosed in Patent Document 1 prevents erroneous administration of pharmaceutical products. As shown in FIG. 6 (a), a tag having a memory for reading and writing information is attached to a medicine package. The tag may be attached directly to the packaging of the medicine, or may be attached via something. Various information is read and written to the tag until the medicine is administered to the patient.

  The “blister wrapping machine” disclosed in Patent Document 2 has a tag attaching function, and can suppress damage to the tag during blister sheet manufacturing. As shown in FIG.6 (b), a pocket part is formed in a packaging film. Fill tablets into pockets. A packaging film and a cover film are heated and pressed together to form a PTP film. Print a printable tag on the packaging film side. Affix a protective sticker over the printable tag. Record information for each printable tag, punch out the PTP film, and make it into a PTP sheet.

The “medicine container” disclosed in Patent Document 3 enables tracing of information about a medicine even after it reaches the hand of a patient. As shown in FIG.6 (c), the chemical | medical agent of the minimum dosage unit is accommodated separately in the accommodating part of a main-body part. A unique drug ID is held in the IC tag for each drug in the minimum dose unit contained in the main body. By reading the information held in the IC tag, it is possible not only to identify the type of drug, but also to identify the drug in the minimum dose unit individually. As with out-of-hospital prescription drugs, patients take drugs from hospitals and pharmacies and use it outside the hospital to see what kind of drugs it is, who prescribes, and who dispenses it. You can trace when the deadline is.

  However, the conventional pharmaceutical package with an IC tag has the following problems. Since the IC tag can operate even after the patient has taken the medicine, it cannot be determined whether or not the patient has taken the medicine. Of course, the time of taking cannot be recognized. In addition, some unused drugs cannot be recognized and managed individually.

  An object of the present invention is to solve the above-mentioned conventional problems and to selectively read information on only unused medicines at a high speed and simultaneously by a non-contact electronic tag that is broken and does not operate when the medicine is taken out. It is also possible to use a non-contact electronic tag-attached pharmaceutical package so that the patient can recognize the time when the medicine was taken.

  In order to solve the above problems, in the present invention, a main body sheet, a concave storage portion formed on one side of the main body sheet, and a material attached to the main body sheet are hermetically sealed in the storage portion for protection. An IC part having a wireless communication function, and an antenna part that is cut when the cover sheet is broken, on the contactless electronic tag of the protective sheet comprising the cover sheet to be attached and the contactless electronic tag mounted on the cover sheet It was set as the structure provided with.

  Moreover, the antenna part was formed one by one on the cover sheet | seat of the range which seals and seals one accommodating part. Or the antenna part was formed one by one on the lid sheet of the range which seals and seals a some accommodating part. Moreover, the antenna part was formed on the lid sheet by vapor deposition or printing. Further, the non-contact electronic tag is provided with storage means for storing at least one of the item name, lot number, expiration date, quantity, and unique identification code of the stored items. In addition, the stored items were pharmaceuticals, and a PTP sheet was composed of a main body sheet and a lid sheet. In addition, the stored items were drugs in which a plurality of types or a plurality of internal drugs were preliminarily prescribed as a single dose.

  In addition, a protective sheet storage case, a storage unit that stores a protective sheet having a non-contact electronic tag, a lid that covers the storage unit, a reader that communicates with the non-contact electronic tag, and a protective sheet are stored in the storage unit And a control means for controlling the reader so as to communicate with the non-contact electronic tag only when the lid is closed. In addition, a time data generator and a memory that records information acquired by the reader communicating with the contactless electronic tag and communication time information output from the time data generator are provided.

  By configuring as described above, it is possible to recognize that the content has been taken out and also the time when the non-contact electronic tag is destroyed and communication is impossible. In addition, since a non-contact electronic tag is attached to each drug, it is possible to accurately manage inventory even for some unused drugs by simultaneously reading information from a plurality of electronic tags at high speed.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS. 1 and 2. FIG.

  An embodiment of the present invention is a protective sheet including a contactless electronic tag having an antenna that is cut when a lid sheet of a PTP sheet is broken.

  FIG. 1 is a conceptual diagram of a protective sheet in an embodiment of the present invention. In FIG. 1, a PTP sheet 1 is a packaging material such as pharmaceutical capsules and tablets. The non-contact electronic tag 2 receives radio waves from a reader as operating power, communicates with the reader wirelessly to transmit data, and stores the received data. It is also possible to transmit only the ID code without having a memory. The pharmaceutical capsule 3 is a pharmaceutical capsule stored in a PTP sheet. It may be a tablet or any other form of pharmaceutical product. The main body sheet 11 is a plastic plate serving as a base of the PTP sheet. The lid sheet 12 is a dielectric material that can protect the aluminum foil that seals the housing portion of the main body sheet or the internal medicine from moisture and outside air. The IC unit 21 is an IC part of the non-contact electronic tag. The antenna part 22 is an antenna part of the non-contact electronic tag.

  FIG. 2 is a conceptual diagram of the protective sheet storage case. FIG. 2A is a perspective view of the protective sheet storage case. FIG. 2B is a conceptual diagram showing a cross section of the protective sheet storage case. FIG. 2C is a functional block diagram of a reader and the like. In FIG. 2, the storage part 31 is a part which stores a protection sheet. The lid portion 32 is a lid that covers the storage portion. The reader 33 is means for communicating with the non-contact electronic tag and acquiring data. The time data generator 34 is a clock that outputs time data as digital data. The control unit 35 is a means for controlling the reader so that it can communicate only when the lid is closed, for example, a hinge switch. The memory 36 is a memory for recording data read from the non-contact electronic tag and the time.

  The function and manufacturing method of the protective sheet in the embodiment of the present invention configured as described above will be described. Initially, the outline | summary of a protection sheet is demonstrated, referring FIG. A medicine capsule 3 is hermetically sealed with a lid sheet 12 in a housing portion of the main body sheet 11. A non-contact electronic tag 2 is attached on the lid sheet 12. The antenna portion 22 of the non-contact electronic tag 2 is cut when the lid sheet 12 is broken. One antenna section 22 may be provided in each storage section, or one antenna section 22 may be provided in each of a plurality of storage sections.

  Next, the manufacturing method of a protection sheet is demonstrated, referring FIG. A concave storage portion is formed on one side of the main body sheet 11 of the PTP sheet. Place the pharmaceutical capsule 3 in the storage. It may be a pharmaceutical tablet, or a medicine in which a plurality of types or a plurality of internal medicines are prescribed in advance as a single dose. The lid sheet 12 is attached to the main body sheet 11, and the pharmaceutical capsule 3 is hermetically sealed and protected. When taking the pharmaceutical capsule 3, the lid capsule 12 can be broken to take out the pharmaceutical capsule 3. So far, it is the same as the conventional PTP sheet.

  A non-contact electronic tag 2 including an IC part 21 and an antenna part 22 is formed on the lid sheet 12. One antenna portion 22 is formed on the lid sheet 12 in a range where one storage portion is hermetically sealed. Alternatively, one antenna portion 22 may be formed on the lid sheet 12 in a range in which a plurality of storage portions are hermetically sealed. The antenna unit 22 is formed on the lid sheet 12 by vapor deposition or printing. The contactless electronic tag 2 stores at least one of the product name, lot number, expiration date, quantity, and unique identification code of the corresponding pharmaceutical capsule 3. When taking out the pharmaceutical capsule 3, the lid sheet 12 is broken, and at the same time, the antenna part 22 of the non-contact electronic tag 2 is surely cut so that the lid sheet 12 at the center of the antenna part 22 is easily broken. A part is provided. The lid sheet 12 uses a dielectric so as not to interfere with communication between the non-contact electronic tag 2 and the reader. Alternatively, an antenna part is provided on a cover sheet made of aluminum foil with a dielectric interposed therebetween so that the non-contact electronic tag 2 and the reader can communicate with each other. In this way, a non-contact electronic tag can be formed on the protective sheet at a low cost.

  Next, a case for storing the protective sheet will be described with reference to FIG. The protective sheet storage case includes a storage unit 31 for storing the protective sheet and a cover unit 32 that covers the storage unit 31. The storage unit 31 includes a reader 33 for communicating with the contactless electronic tag 2, a time data generator 34 that is a clock that outputs time data as digital data, and a reader 33 only when the lid 32 is closed. Are provided so as to be communicable, and a memory 36 for recording data read from the non-contact electronic tag 2 and its time is provided. Some or all of these may be provided in the lid portion 32.

  When the protective sheet is stored in the storage unit 31 and the lid unit 32 is closed, the reader 33 communicates with the non-contact electronic tag 2 under the control of the control unit 35. The information acquired by the reader 33 communicating with the non-contact electronic tag 2 and the time information output from the time data generator 34 at that time are recorded in the memory 36. The protective sheet storage case is collected at an appropriate time, and the data in the memory 36 is taken out and analyzed. Based on the time information, the non-contact electronic tag 2 that cannot be communicated can be obtained from the time-series communication record. Let the last communication time be the time of taking the pharmaceutical capsule corresponding to the lost contactless electronic tag 2.

  In the case of the last pharmaceutical capsule of the protective sheet, only the last communication time is known, but in other cases, the time when the protective sheet is returned is known, and it may be used as the time of taking. The protective sheet is taken out from the protective sheet storage case and the pharmaceutical capsule is taken out immediately, and it is considered that the pharmaceutical capsule is taken and immediately returned to the protective sheet storage case. The time error is about 1 minute. In this way, it is possible to recognize that the item (medicine) inside the protective sheet has been consumed by breaking the non-contact electronic tag formed for each individual pharmaceutical in the protective sheet.

  By reading a plurality of non-contact electronic tag information simultaneously at high speed with an ordinary reader / writer, inventory management operations such as inventory can be made more efficient as in the conventional case. Furthermore, since it is possible to recognize which medicines are unused even for partially unused protective sheets, inventory management can be accurately performed even during continuous medication in a hospital or the like. By using the protective sheet and the protective sheet storage case as a pair, the time when the medicine is used (taken) can be acquired correctly. This protective sheet can be applied to other than pharmaceutical capsules and tablets. For example, it can be used for medicines for animals and plants, food and fertilizer, and the time used can be specified.

  As described above, in the embodiment of the present invention, the protective sheet is configured to include a non-contact electronic tag having an antenna that is cut when the lid sheet of the PTP sheet is broken, so that a pharmaceutical capsule or the like is taken out. Can recognize the time.

  The protective sheet of the present invention is most suitable as a protective sheet for electronically monitoring the usage status of pharmaceuticals hermetically sealed in a PTP sheet or the like.
