  Next, a medical handpiece which is an example of the medical instrument 4 will be described. FIG. 3 is a schematic diagram for explaining the configuration of the medical handpiece 30 according to the first embodiment. The medical handpiece 30 as the medical instrument 4 includes a main body portion 31 and a grip portion 32 to be gripped by an operator. Further, the medical hand piece 30 is located at a position that does not become the grip portion 32, for example, at a rear outer peripheral position of the main body portion 31. , An RFID tag 40 is attached. In addition, by providing the outer peripheral groove with which the band part of the RFID tag 40 abuts on the main body part 31, displacement of the RFID tag 40 is prevented and positioning becomes easy.

  The RFID (Radio Frequency IDentification) tag 40 is a rubber band type IC tag that can be attached to the medical instrument 4 such as the medical handpiece 30. The RFID tag 40 includes a band, a protection member, and an RFIC (Radio Frequency Integrated Circuits) chip. The band has a ring shape that has elasticity and can be attached to a medical instrument. For the band portion, for example, a fluorine rubber resistant to an autoclave is used.

  The RFIC chip is provided in a part of the band unit, and can store an identification number, which is identification information of a medical device. The RFIC chip can read and write information by short-range wireless communication (several cm to several meters depending on a frequency band) using an electromagnetic field, a radio wave, or the like. Note that the RFIC chip is a passive RFIC chip connected to an antenna (not shown). Therefore, the RFIC chip operates using radio waves from a reader (reader) as an energy source, and there is no need to incorporate a battery in the RFID tag 40. Note that the RFIC chip is not limited to a passive type RFIC chip, and may be an active type RFIC chip connected to a battery built in the RFID tag 40.

  The protection member seals the RFIC chip on the band portion by a rubber molding technique. The protection member has heat resistance, and seals the RFIC chip to improve processing such as washing and sterilization, for example, the resistance of the autoclave. Further, in the protection member, the shape of a portion covering the RFIC chip is a convex curved surface. As a result, the radio wave from the reader / writer can be easily received by an antenna (not shown), and since there is no portion to be caught by the RFID tag 40, it does not hinder the operator even when attached to a medical handpiece.

  Two types of frequency bands that can be used for the RFID tag 40 can be used in Japan: an HF band (13.56 MHz) and a UHF band (915 MHz to 930 MHz). The HF band is widely used in non-contact IC cards and the like, and the RFID tag 40 can be read at a very short distance. On the other hand, in the UHF band, it is possible to expect the re-entry of radio waves as compared with the HF band, and the RFID tag 40 can be read at a distance farther than the HF band. Note that the frequency band that can be used for the RFID tag 40 is not limited to the above-described frequency band, and may be changed depending on countries and regulations.

  In the medical handpiece 30 shown in FIG. 3, the identification number of the medical handpiece 30 is attached as a two-dimensional identification code 400 with a laser marker on the main body 31 near the RFID tag 40. In FIG. 3, the identification number of the medical handpiece 30 is given as the two-dimensional identification code 400, but may be a one-dimensional identification code such as a barcode. The position where the two-dimensional identification code 400 is provided may be any position on the medical handpiece 30, but in consideration of the wear of the identification code, a position other than the grip portion 32, preferably the outer periphery of the rear portion of the main body 31. It is desirable that Further, the two-dimensional identification code 400 may be attached to the medical handpiece 30 by printing or the like, instead of being attached to the medical handpiece 30 with a laser marker. In the medical handpiece 30, a tube for supplying a working medium such as water, air, or electricity connected from the medical care device 10 is connected to a connection portion provided at the rear.

  The RFID tag 40 stores a unique identification number corresponding to each medical handpiece 30, but can be detached from the medical handpiece 30. Therefore, there is a possibility that the RFID tag 40 is erroneously attached to the medical handpiece 30 having a different identification number. Therefore, the medical handpiece 30 is given a unique identification number as a two-dimensional identification code 400 in advance. Therefore, in the medical treatment device 10, it is possible to confirm whether or not the identification number of the RFID tag 40 attached to the medical handpiece 30 is correct. When the identification number of the two-dimensional identification code 400 is different from the identification number of the RFID tag 40, the reader / writer 10a may write the mismatch information to the RFID tag 40 or display it on the display monitor 6. Of course, it is not always necessary to provide both the RFID tag 40 and the two-dimensional identification code 400 in the medical handpiece 30 and the medical device 4, and a configuration in which either one is provided may be used.

  Next, the configuration of the RFID tag 40 will be described with reference to the drawings. FIG. 4 is a block diagram for explaining the internal configuration of the RFID tag 40 according to the first embodiment. The passive type RFID tag 40 includes an RFIC chip 45. The RFIC chip 45 includes a communication unit 41, a control unit 42, and a storage unit 44.

The reader / writer 80a (hereinafter, these are also collectively referred to as a “reader / writer”) can communicate with a communication unit 91 included in each of the reader / writers 80a. Specifically, when the RFID 40 approaches the communication range (readable range) of the reader / writer, the coil 41a included in the communication unit 41 on the RFID side and the coil 91a included in the communication unit 91 on the reader / writer side change. Electromagnetic coupling occurs. The reader / writer can read and write information stored in the RFID tag 40 using electromagnetic coupling generated between the reader / writer and the RFID tag 40. In addition, the passive RFID tag 40 is driven by using power supplied by electromagnetic coupling generated between the RFID tag 40 and a reader / writer. The reader / writer 10a is arranged so that the surface on which the coil 91a is provided is the surface of the tray table 3 on which the reader / writer 10a is provided.

  The control unit 42 updates the information stored in the storage unit 44 or stores new information in the storage unit 44 based on the information exchanged with the reader / writer via the communication unit 41.

  The RFIC chip 45 is connected to a warning unit 43 built in the RFID tag 40. The warning unit 43 may be an LED electrically connected to the RFIC chip 45, a lamp other than the LED, or a speaker electrically connected to the RFIC chip 45. You may. When the warning unit 43 is a lamp, the warning unit 43 lights or blinks in a lighting color indicating a warning based on control by the control unit 42 when a maintenance error occurs. When the warning unit 43 is a speaker, the warning unit 43 outputs a warning sound indicating a warning based on control by the control unit 42 when a maintenance error occurs.

  The warning unit 43 is driven by the power supplied from the RFIC chip 45. As described above, since the RFIC chip 45 is supplied with power by electromagnetic coupling generated in communication with the reader / writer, the warning unit 43 is provided by communication between the communication unit 41 and a reader / writer attached to the medical device 10 or the like. Power is supplied by electromagnetic coupling.

  The information stored in the storage unit 44 includes an identification number, an installation date, a management number, an operator number, a patient number, a warning flag, a management flag, a cleaning time, a refueling time, and a sterilization time. , The number of times of cleaning, the number of times of refueling, and the number of times of sterilization.

  The identification number is identification information for identifying the medical device 4 such as a unique serial number assigned to the medical device 4 to which the RFID tag 40 is attached. For example, in the example of FIG. 4, “L102G12345K−” is stored in the storage unit 44 as identification information capable of specifying “L102G12345K” which is an identification number such as a serial number. By storing the identification number in the RFID tag 40, the medical instruments 4 can be individually managed.

  The installation date is date information for specifying a date when the use of the medical device 4 is started or a date when the medical device 4 is manufactured. For example, in the example of FIG. 4, “180122-1” is stored in the storage unit 44 as date information capable of specifying the installation date “January 22, 2018”. By storing the installation date in the RFID tag 40, the use period of the medical device 4 and the remaining warranty period can be managed.

  The management number is identification information assigned to the medical device 4 in order to individually manage the medical device 4 in a hospital, a university, or the like separately from the identification number. For example, in the example of FIG. 4, “K010” is stored in the storage unit 44 as identification information capable of specifying the management number “K010”. By storing the management number in the RFID tag 40, the medical instruments 4 can be individually managed within a limited range.

  The operator number is identification information for identifying an operator using the medical instrument 4. For example, each operator is assigned an operator number from “A” to “Z”, and in the example of FIG. 4, identification information that can specify “C” as the operator number is provided. It is stored in the storage unit 44.

  The patient number is identification information for identifying a patient to be treated using the medical device 4. For example, one of patient numbers “001” to “999” is assigned to each patient, and in the example of FIG. 4, the storage unit 44 stores identification information that can specify “230” as the patient number. Is stored in

  The warning flag is a flag that can specify whether a maintenance error has occurred. For example, if there is no maintenance error, “0” is assigned as a warning flag, and if there is a maintenance error, “1” is assigned as a warning flag. In the example of FIG. 4, “0” indicating that there is no maintenance error is stored in the storage unit 44 as a warning flag. By storing a warning flag in the RFID tag 40, the presence or absence of a maintenance error can be managed.

  The management flag is a flag that can specify whether or not the process of each process in the maintenance has been performed, and can specify whether or not the process has been performed by each of the plurality of processing devices in a predetermined process order. It is stored in the storage unit 44 in a manner. For example, “0” is assigned to each of the washing process, the refueling process, and the sterilization process as flag information when not processed, and “1” is assigned as flag information when processed. . Further, the management flag is composed of three digits, the first digit contains flag information corresponding to the cleaning process, the second digit contains flag information corresponding to the refueling process, and the third digit contains flag information corresponding to the sterilization process. Are located.

  In the management flag, if all the processes are completed, “111” is stored in the storage unit 44, and if none of the processes is completed, “000” is stored in the storage unit 44. . In the example of FIG. 4, “110” is stored in the storage unit 44 as the management flag. That is, since the first digit is “1”, it can be specified that the cleaning process has been completed. Since the second digit is “1”, it can be specified that the refueling process has been completed. Since the third digit is “0”, it is possible to specify that the sterilization process has not been completed. By storing the management flag in the RFID tag 40, it is possible to determine whether or not each process in the maintenance has been performed, and whether or not each of the plurality of processing devices has performed the process in a predetermined process order. Can be managed.

  The cleaning time is time information for specifying the time at which cleaning was performed. For example, in the example of FIG. 4, “1250” is stored in the storage unit 44 as time information that can specify “12:50”, which is the time at which cleaning was performed. By storing the cleaning time in the RFID tag 40, the time at which cleaning is performed can be managed.

  The refueling time is time information for specifying the time at which refueling was performed. For example, in the example of FIG. 4, “1315” is stored in the storage unit 44 as time information that can specify “13:15” that is the time at which refueling was performed. By storing the refueling time in the RFID tag 40, the time at which refueling was performed can be managed.

  The sterilization time is time information for specifying the time at which the sterilization was performed. For example, in the example of FIG. 4, “1340” is stored in the storage unit 44 as time information that can specify “13:40”, which is the time at which sterilization was performed. The sterilization time can be managed by storing the sterilization time in the RFID tag 40.

  The processing times such as the cleaning time, the refueling time, and the sterilization time are, as with the management flag, whether or not the processing of each step in the maintenance has been performed, and each of the plurality of processing apparatuses in a predetermined process order. This is an embodiment of “specific information” because it is information that can manage whether or not the process has been performed.

  The number of times of cleaning is frequency information for specifying the total number of times the medical device 4 has been cleaned. For example, in the example of FIG. 4, “0105” is stored in the storage unit 44 as the number-of-times information that can specify “105 times” that is the number of times of cleaning. By storing the number of times of cleaning in the RFID tag 40, the total number of times of cleaning can be managed.

  The number of times of refueling is frequency information for specifying the total number of times that the medical device 4 has been refueled. For example, in the example of FIG. 4, “0105” is stored in the storage unit 44 as the number-of-times information that can specify “105 times” that is the number of times of refueling. By storing the number of times of refueling in the RFID tag 40, the total number of times of refueling can be managed.

  The sterilization frequency is frequency information for specifying the total number of times the medical instrument 4 has been sterilized. For example, in the example of FIG. 4, “0105” is stored in the storage unit 44 as “105 times”, which is the number of times sterilization has been performed, as identifiable number information. By storing the number of times of sterilization in the RFID tag 40, the total number of times of sterilization can be managed.

  Further, an extension area (empty area) is secured in the storage unit 44, and new information can be added to the extension area in the future and stored. The storage unit 44 can store various information in this extended area. For example, the extension area can additionally store information for the surgeon to individually manage. The information stored in the storage unit 44 including the information stored in the extension area can be read, for example, by the reader / writer 10a, and stored and managed in a server on the cloud connected to the computer 20. With this configuration, the information in the storage unit 44 of each medical device 4 can be stored in association with each medical device 4 by the server on the cloud having a large storage capacity. Even if is damaged, the information in the storage unit 44 of each medical instrument 4 can be inherited and managed by the server as a backup.

  The storage information in the storage unit 44 illustrated in FIG. 4 is an example, and other information may be stored, or may be stored in a mode different from that in FIG.

  In addition, FIGS. 5 and 6 have described the case where the dentists 700 and 700a perform the treatment while sitting directly above the patient 702. However, the dentists 700 and 700a change their positions with respect to the patient 702 according to the contents of the treatment. FIG. 7 is a schematic diagram for explaining a positional relationship between the medical care apparatus according to the first embodiment and an operator. When the position where the dentists 700 and 700a sit directly above the head of the patient 702 is the 12 o'clock position, and this is the home position, the position moved 90 degrees clockwise as shown in FIG. The position moved 90 degrees in the counterclockwise direction is the position at 9 o'clock.

  When the dentists 700, 700a move from the home position to the 3 o'clock position, the working ranges 710, 710a, 720, 720a also move 90 degrees clockwise according to the movement. When the dentists 700, 700a move from the home position to the 9 o'clock position, the working ranges 710, 710a, 720, 720a also move 90 degrees in the counterclockwise direction according to the movement.
