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.

  Since patients who have undergone surgery such as gastrointestinal surgery are often unable to take orally, their nutritional management is generally performed by high-calorie infusion (IVH) for central intravenous administration. In IVH, carbohydrates, amino acids, and electrolytes, which are nutrient sources, are usually administered. For example, when glucose and amino acids are stored in the same container and stored, these solutions turn brown due to the so-called Maillard reaction. Need to be stored separately. For this reason, infusion bags that individually store these drugs have recently become widespread (see Patent Document 1).

  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 barcode reader 11, a patient information reader 12, and an RFID reader / writer 13 are connected to the terminal 10.

  The barcode reading unit 11 includes a known barcode reader, and is printed on a label attached to the container 1, 2, 3 (may be directly printed on each container). The barcodes 1a, 2a, and 3a are read and temporarily stored in the HDD 10c of 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, the patient information database included in the terminal 10, the host computer 20 or other information processing apparatus is searched, and the search result is included in the patient information. Also good. With 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) can be obtained from the host computer 20 and included in the patient information. it can. 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 for performing data communication with the IC tag 40 attached to the medicine container 4, and is a well-known RFID communication unit (transmission unit / reception unit) (not shown), which controls the whole. And a communication I / F (interface) for exchanging data with the terminal 10.

(S12, corresponding to the drug information acquisition step of the present invention). A configuration may be used in which only the barcode number is acquired as drug information without constructing the drug database. The acquired medicine information is temporarily stored in the HDD 10c. You may display medicine information on the display part 10a.

  When the patient information and all the drug information are acquired (S13: Yes), a screen as shown in FIG. 4 is displayed on the display unit 10a of the terminal 10. Here, when the “Register” button is clicked, the patient information and all drug information are written by the RFID reader / writer 13 into the storage unit 41b included in the IC chip 41 of the IC tag 40 attached to the drug container 40 ( S14, corresponding to the drug information writing step of the present invention).

  FIG. 4 shows an example of a display screen on the display unit 10a of the terminal 10 when the medicine information reading / writing process is executed. The patient number (when the patient information can be acquired) and the breakdown of the mixed drugs are 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 a storage example of drug information in the drug database included in the DB 21 of the host computer 20. In association with the barcode number of the barcode 1a printed on the label affixed to the container 1, the drug product number, product name, content, date of manufacture, and expiration date are stored. (The same applies to the drugs corresponding to the barcodes 2a and 3a).

  FIG. 6 shows a storage example of drug information in the storage unit 41b of the IC chip 41. The drug information acquired from the DB 21 of the host computer 20 is stored together with the read barcode number. Only a barcode number may be stored as medicine information. The unique code is the only code in the world stored in each IC chip. You may memorize | store the mixed injection date of a chemical | medical agent.

  FIG. 7 shows an example of storing patient information in the storage unit 41 b of the IC chip 41. In addition to the medical record number, the patient name, disease name, prescription history (prescription date, prescription content) are stored. Only the medical record number or only the patient name may be stored.

  The drug information matching 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, drug information and patient information (referred to as IC tag information) are read by the RFID reader / writer 13 from the storage unit 41b included in the IC chip 41 of the IC tag 40 attached to the drug container 4 (S31, of the present invention). Equivalent to drug information reading process). 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. 3 (S32). At this time, dispensing instruction information is also acquired. The acquired patient information and dispensing instruction information are temporarily stored in the HDD 10c.

  Next, the medicine information and patient information read from the storage unit 41b of the IC chip 41 is collated with the dispensing instruction information and patient information acquired from the patient information reading unit 12 (S33, corresponding to the collation process of the present invention).

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

  In the above example, patient information is stored in the IC tag, but patient information may not be stored in the IC tag. In this case, the step of acquiring patient information in FIGS. 3 and 8 is not executed. If the medicine information and the dispensing instruction information match, it can be determined that the medicine is correctly prescribed.

  In the above example, the barcodes 1a, 2a, 3a are printed on the labels attached to the containers 1, 2, 3, but the IC tag storing the drug information is attached to the containers 1, 2, 3. It is good also as a structure to stick. This eliminates the need to store drug information in the DB 21 of the host computer 20. Of course, drug names, barcodes, etc. may be printed on the surface of these IC tags.

  In the example of FIG. 5, only the barcode number may be stored in the IC tag 40. In this case, in the medicine information collation process of FIG. 8, the barcode number read from the IC tag 40 is collated with the barcode number included in the dispensing instruction information described or stored in the medical record or prescription.

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