Description

  The present invention relates to a method for using an IC tag.

  A wireless IC tag (also referred to as an RFID tag) can be written to and read from a bar code and can handle a large amount of information.

  For example, non-contact such as an IC tag / IC card including a non-contact communication unit and a data storage memory storing at least drug-specific data including a drug name and a remaining amount in a container containing a drug stored in a storage. A non-contact type read / write device including a non-contact communication unit and a control unit capable of reading and writing data storage memory was installed at the dispensing site while a type IC medium was attached, and a medicine was picked from the storage together with the container. Later, before dispensing, the container containing the medicine is brought close to the non-contact type read / write device, and the medicine specific data stored in the data storage memory of the non-contact type IC media is communicated with each other without contact. A dispensing error prevention support system has been devised that is configured to be read by the control unit of the non-contact type read / write device via the unit (see Patent Document 1).

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing a concept of a method for using an IC tag according to the present invention. The IC tag utilization method has the following configuration. The drug container 1 is composed of a drug container 1 containing a drug solution such as an anticancer drug, and syringes (also referred to as syringes and syringes) 2, 3 which are subdivided containers for dividing the drug solution stored in the drug container 1. Are attached with IC tags 40 and 50 (in this case, two) corresponding to the number of subdivided containers. When the drug solution in the drug container 1 is subdivided into syringes 2 (administered to patient A) and 3 (administered to patient B), the amount of drug solution subdivided into IC tags 40 and 50 (ie, dose information) is recorded. . Details will be described below.

  Although the chemical | medical agent accommodated in the chemical | medical agent container 1 is mainly a chemical | medical solution, not only a chemical | medical solution but a tablet and a granular chemical | medical agent may be used, and several chemical | medical agents may be mixed. Moreover, there is no restriction | limiting in the shape of a container, An ampule type container may be sufficient. Of course, in addition to the syringe, a container of another shape such as a cylindrical container may be used as the subdivided container.

  FIG. 2 shows a configuration example of a device used for inputting and collating various information. In the example of FIG. 2, the terminal 10 and the host computer 20 that are network-connected so as to be communicable are configured as main elements.

  The terminal 10 is configured as a personal computer, for example, and includes a display unit 10a such as an LCD display, an input unit 10b such as a keyboard, a storage medium such as a hard disk device (HDD) 10c, and a control unit 10d that controls these. Another information communication terminal such as a PDA (Personal Digital Assistant: portable information terminal) may be used. In addition, a patient information reading unit 12 and an RFID reader / writer 13 are connected to the terminal 10.

  The patient information reading unit 12 includes, for example, one or more of a magnetic card reader, an IC card reader, or a barcode reader that reads the content of a barcode attached to a medical chart. In recent years, digitization of medical examination tickets and medical charts has progressed, and patient names and the like are stored in magnetic cards and IC cards. The bar code is printed on a medical examination ticket or medical record so that the patient can be identified. The magnetic card, IC card, and bar code information (that is, patient information) is read and temporarily stored in the HDD 10c of the terminal 10. In addition, patient information may be input from the input unit 10 b of the terminal 10.

  By performing a predetermined operation on the terminal 10 based on the read patient information, a patient information database included in the terminal 10, the host computer 20, or another information processing apparatus is searched, and the search result is used as additional information for patient information. May be included. By this method, even if only the patient's name is stored in the magnetic card, IC card, and barcode, information necessary for treatment (additional information) is obtained from the host computer 20 and included in the patient information. Can do. In addition to the patient's name, information such as height, weight, blood type, medical history, etc. is being stored in the electronic examination ticket. Such information may be read as additional information and included in patient information.

  In addition, although patient information is enough to specify a patient only with a medical chart number or a medical examination ticket number, it is possible to specify a patient more accurately when the above-mentioned additional information is included.

  The RFID reader / writer 13 is used to perform data communication with the IC tags 40 and 50 attached to the medicine container 1, and a well-known RFID communication unit (transmitting unit / receiving unit) (not shown) A control unit for controlling and a communication I / F (interface) for exchanging data with the terminal 10 are included.

  The IC tag 40 (same for 50) includes a known IC chip 41 and peripheral circuits (not shown) such as an antenna. The IC chip 41 includes a control unit 41a that controls the operation, and a storage unit 41b that stores a unique code assigned to the IC chip 41, IC tag information described later, and the like.

  Further, when the IC tag 40 is irradiated with radio waves from the RFID reader / writer 13, the energy of the radio waves is converted into electric energy and the control unit 41 a operates to be included in the radio waves from the RFID reader / writer 13. Based on the control command, predetermined information such as IC tag information is read from the storage unit 41 b and transmitted to the RFID reader / writer 13. Further, based on the control command included in the radio wave from the RFID reader / writer 13, the control unit 41a writes the data transmitted from the RFID reader / writer 13 to the storage unit 41b.

  The host computer 20 is configured as a well-known personal computer or workstation, and a database (DB) 21 is constructed on a storage medium such as an HDD.

  As long as the host computer 20 and the terminal 10 are connected via a network, the installation position is not limited. For example, the host computer 20 is installed in a facility such as a computer room, and the terminal 10 is installed in a facility for subdividing medicine and a facility (such as a hospital room) that uses the subdivided medicine. Further, a database equivalent to the DB 21 may be constructed in the HDD 10 c of the terminal 10.

  In the configuration of the present invention, the drug solution stored in the drug container 1 is subdivided into syringes 2 and 3 based on drug administration information described or stored in a medical chart or prescription.

  With reference to FIG. 3, an IC tag information registration process for registering information in an IC tag of a subdivided container when the chemical solution in the medicine container 1 is subdivided will be described. This process is included in the application program stored in the HDD 10c of the terminal 10, and is executed by the control unit 10d.

  Prior to the execution of this process, based on the drug administration information, the drug solution in the drug container 1 is subdivided into syringes 2 (corresponding to the drug subdivision process of the present invention), and the IC tag 40 attached to the drug container 1 is labeled as a drug. It peels from the container 1 and sticks to the syringe 2 (equivalent to the re-sticking process of this invention). In addition, you may perform these processes after execution of this process. The drug administration information is described in, for example, a medical record or a prescription. When the medical record or prescription is digitized, dosage information is acquired using a reading device such as an IC card reader or a barcode reader. Moreover, you may acquire dosage information from the input part 10b of the terminal 10. FIG.

  In this process, first, patient information is acquired from the patient information reading unit 12 by the method as described above (S11, corresponding to the patient information acquisition step of the present invention). The acquired patient information is temporarily stored in the HDD 10c. Patient information may be displayed on the display unit 10a.

  Next, based on the drug administration information, information (dose information) regarding the dose of the drug solution to be administered to the patient is acquired (S12). The acquired dose information is temporarily stored in the HDD 10c. The dose information may be displayed on the display unit 10a.

  If patient information and dosage information are acquired (S13: Yes), a screen like FIG. 4 will be displayed on the display part 10a of the terminal 10. FIG. Here, when the “register” button is clicked, the patient information and the dose information are written as IC tag information into the storage unit 41b included in the IC tag 40 attached to the syringe 2 by the RFID reader / writer 13 (S14, "Registered", corresponding to the IC tag information writing process of the present invention).

  When there is a remaining amount of the chemical in the drug container 1 (S15: Yes), the RFID reader / writer 13 writes the information on the remaining amount of the drug in the IC tag 50 attached to the drug container 1 (S16).

  The remaining drug solution (3 ml) can be administered to another patient (patient B). In this case, the patient information and the dose information (same as the liquid amount information in the example of FIG. 1) regarding the patient B are written in the storage unit of the IC tag 50, and the IC tag 50 is reattached to the syringe 3. .

  In the above example, it is assumed that the chemical solution is subdivided into two syringes. However, when subdividing into three or more syringes, a new IC tag is attached to the drug container 1. At this time, the medicine information stored in advance is read from the IC tag 50 attached to the medicine container 1 by the RFID reader / writer 13 and written into a new IC tag.

  The above-described drug information, drug administration information, patient information, dose information, and drug remaining amount information may be associated with each other and registered in the DB 21 of the host computer 20 as drug administration history information. Thereby, it becomes possible to grasp the administration history of medicines even outside the site.

  FIG. 4 shows an example of a display screen on the display unit 10a of the terminal 10 when the IC tag information registration process is executed. The breakdown of the medicine divided by patient number is displayed. On this screen, when the “correction” button is clicked and either patient information or drug information is selected (clicked), the corresponding portion can be read again (corrected).

  FIG. 5 shows an example of drug information stored in advance in the IC tags 40 and 50. In the example of FIG. 5, a unique code, a drug product number, a product name, a content, a manufacturing number (also referred to as a lot number), an expiration date, and a serial number are stored. Since the serial number is different for each medicine container even in the same product, it can be specified from which serial number the medicine container is subdivided. These pieces of information are information at the time of shipment from the pharmaceutical company that manufactured the drug solution. The unique code is the only code in the world stored in each IC chip.

  FIG. 6 shows an example of patient information and dose information additionally stored in the IC tags 40 and 50. In the example of FIG. 6, the patient information includes a medical record number (may be a prescription number), a patient name (patient A), and a disease name, and the dosage information includes the prescribed drug name and the dose of the drug. (7 ml) is included.

  FIG. 7 shows an example of chemical solution remaining amount information additionally stored in a storage unit (not shown) of the IC tag 50. The chemical solution remaining amount information includes the subdivided date and time and the remaining amount of the drug. Information (name, etc.) about the patient to be prescribed may be included.

  The drug administration information collation process will be described with reference to FIG. This process is included in the application program stored in the HDD 10c of the terminal 10, and is executed by the control unit 10d. First, dose information and patient information (referred to as IC tag information) are read by the RFID reader / writer 13 from the storage unit 41b of the IC chip 41 included in the IC tag 40 attached to the syringe 2 (S31, of the present invention). Equivalent to the IC tag information reading step). The read IC tag information is temporarily stored in the HDD 10c.

  Next, patient information is acquired from the patient information reading unit 12 by the same method as in step S11 of FIG. At this time, drug administration information is also acquired by the method described above (S32). The acquired patient information and drug administration information are temporarily stored in the HDD 10c.

Next, both the IC tag information (dose information and patient information) read from the storage unit 41b of the IC chip 41, the patient information acquired from the patient information reading unit 12, and the drug administration information are collated (S33). , Equivalent to the verification process of the present invention). For example, when any of the following matches, it is determined that the two match.
-The serial number of the drug solution included in the IC tag information and the drug administration information matches.
-The manufacturing number of the chemical solution included in the IC tag information and the drug administration information matches.
-IC tag information and patient information included in patient information match.

  As a result of the verification, if both match (S34: Yes), both match, such as "This drug solution matches the prescription", "This drug solution is prescribed to the patient XX" Is displayed on the display unit 10a (S35), and if there is no match (S34: No), "This drug solution does not match the prescription" A message to the effect that the two do not match is displayed on the display unit 10a (S36).

  The IC tag information registration process in the case where it is desired to administer the same serial number chemical solution to the same patient or the same serial number (production lot) to the same patient will be described with reference to FIG. Since this process is a modification of the IC tag information registration process in FIG. 3, the same steps as those in FIG. 3 are given the same reference numerals, and detailed description thereof is omitted here.

If patient information and dosage information are acquired (S13: Yes), a screen like FIG. 4 will be displayed on the display part 10a of the terminal 10. FIG. Here, when the “registration” button is clicked, the drug administration history information included in the DB 21 of the host computer 20 as described above is referred to, and the administration history of the drug solution is retrieved using, for example, the serial number, manufacturing number, and patient information as search keywords. Existence is checked (S131). And it is determined whether the administration conditions of the said chemical | medical solution were satisfied using either of the following.
-If there is no history of administration of the drug solution, it is determined that the administration conditions have been met.
・ If the patient has a history of administration of the drug solution (serial numbers match), it is determined that the administration condition has been established.
-If the serial numbers do not match, but the patient has a history of administering the drug solution with the same serial number of the drug solution, it is determined that the administration condition has been established.

  When the administration condition is satisfied (S132: Yes), the patient information and the dose information (that is, IC tag information) are stored in the IC tag 40 attached to the syringe 2 by the RFID reader / writer 13, and the storage unit 41b. (S14).

  When there is a remaining amount of the chemical in the drug container 1 (S15: Yes), the RFID reader / writer 13 writes the information on the remaining amount of the drug in the IC tag 50 attached to the drug container 1 (S16). Finally, the current drug information, patient information, dose information, and drug remaining amount information are associated with each other and registered in the DB 21 of the host computer 20 (S17).

  On the other hand, when the administration condition is not satisfied (S132: No), a warning message such as “This drug solution cannot be prescribed to the patient XX” is displayed on the display unit 10a (S18). Then, this process is complete | finished. After the warning is displayed, it is possible to select whether or not to continue the process, and when continuation is selected, the process may proceed to step S14.

  In the above-described embodiment, the patient information is stored in the IC tag, but the patient information may not be stored in the IC tag. In this case, the step of acquiring patient information in FIGS. 3 and 9 is not executed. 6 and 7 do not include patient information. By collating the serial number of the drug solution, the same drug solution can be administered to the same patient, and wasteful disposal of the drug can be reduced.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
