  The computer 2 of the portable terminal 1 and the computer 5 of the control device 4 are general-purpose computers that include at least a CPU, a memory, a storage device, a communication control device, and a bus that connects these devices. The system can be used. In this computer system, the functions of the computers 2 and 5 are realized by the CPU executing a predetermined program loaded on the memory.

  Next, the processing of this embodiment will be described.

  FIG. 5 is a sequence diagram of a process for administering an infusion to a patient. As pre-processing, an instillation is set in the flow meter 10 (S11), and information (medicine ID, medication conditions) on the medicine and a patient ID to be administered are registered in the storage unit 54 of the control device 4 (S12). Note that information related to the patient such as a patient ID, medicine information prescribed for the patient, and medication conditions is registered in advance in the portable terminal 1 carried by the patient (S13).

  When the nurse finishes preparation for infusion, such as inserting a needle for infusion into the patient, the patient holding the portable terminal 1 and the control device 4 (electrode 903) simultaneously contact each other as shown in FIG. Thereby, between the computer 2 of the mobile terminal 1 and the computer 5 of the control device 4, the transceiver 3 of the mobile terminal 1, the human body of the patient as the electric field transmission medium, the human body of the nurse, and the transceiver 6 of the control device 4. The communication path is established (S20).

  And the transmission part 51 of the control apparatus 4 transmits the chemical | medical agent information (ID12) memorize | stored in the memory | storage part 54 and medication conditions (ID13) to the portable terminal 1 via the said communication channel (S21). The collation unit 22 of the portable terminal 1 collates the information received from the control device 4 with the information registered in the storage unit 23 (S22). Specifically, the collation unit 22 determines that the collation is successful when the received drug information (ID12) and the medication condition (ID13) are present in the storage unit 23, and receives the received drug information (ID12) and the medication condition. When (ID13) does not exist in the storage unit 23, it is determined that the verification has failed.

  When the verification is successful, the transmission unit 21 transmits the patient ID (ID01) registered in the storage unit 23 to the control device 4 via the communication path (S23). In addition, when collation fails, the transmission part 21 transmits the error information which shows that collation failed to the control apparatus 4 via the said communication path. Moreover, the transmission part 21 is good also as transmitting doctor ID registered into the memory | storage part 23 to the control apparatus 4 with error information.

  The collation unit 52 of the control device 4 collates the information received from the mobile terminal 1 with the information registered in the storage unit 54 (S24). Specifically, the collation unit 52 determines whether or not the received patient ID (ID01) matches the patient ID registered in the storage unit 54. If the patient IDs match, the control unit 53 outputs an infusion start instruction including the medication conditions (flow rate measurement etc.) registered in the storage unit 54 to the flow meter 10 (S25).

  When receiving an infusion start instruction, the flow meter 10 sets the designated dosing condition and starts infusion (S26). Note that the flow meter 10 transmits an infusion start message and an infusion end message to the control device 4 at the start of infusion and at the end of infusion, respectively (S27, S30).

  When receiving the drip start message, the transmission unit 51 of the control device 4 transmits the message to the portable terminal 1 via the communication path (S28). The log registration unit 24 of the portable terminal 1 stores log start information including the current date and time in a log information storage unit (not shown) (S29). Moreover, the transmission part 51 of the control apparatus 4 will transmit the said message to the portable terminal 1 via the said communication path, if an infusion end message is received (S31). The log registration unit 24 of the portable terminal 1 stores log end information including the current date and time in the log information storage unit (S32).

  In addition, when the collation process of S22 and S24 fails, the control part 53 stops subsequent processes and performs an error process. As error processing, for example, it is conceivable to stop the flow meter 10 and output an alarm or an error message. In addition, as an error process, the control unit 53 may send an inquiry alert to the doctor stored in the storage unit 54 of the control device 4 (or the storage unit 23 of the portable terminal 1). It is possible to send an alert to a doctor's mail address or make a phone call as an alert to the doctor.

  In the medication control system of the first embodiment described above, the patient has the portable terminal 1, the control device 4 is attached to the infusion flow meter (medical device) 10, and the nurse simultaneously controls the patient and the control device 4. By touching, the communication path is established between the portable terminal 1 and the control device 4 via the human body of the patient and the nurse, and information is transmitted and received. And the portable terminal 1 and the control apparatus 4 each collate a patient and infusion medicine using the received information.

  As a result, in the present embodiment, it is possible to prevent erroneous authentication by using electric field communication that transmits and receives information via an electric field transmission medium, and to realize a collation system that is easier and more convenient. That is, in this embodiment, the portable terminal 1 and the control device 4 (first transmitter / receiver and second transmitter / receiver) are connected to the user and the flowmeter chemicals (first object and second object) attached to each of them. ), It is possible to prevent a medical error (erroneous medication) that administers the wrong medicine to the patient.

  In the present embodiment, since the nurse simply contacts the patient and the control device 4 at the same time, information is transmitted and received between the mobile terminal 1 and the control device 4, so that the bar code reader or RFID reader is operated. Compared with the case where it carries out, the time which collation requires, and the effort of operation can be reduced, and collation can be performed easily.

  In the present embodiment, the collation is performed by both the mobile terminal 1 and the control device 4 (FIG. 5: S22 and S24), but only the control device 4 may perform the collation. In this case, the processing of S21 and S22 shown in FIG. 5 is not performed, and after establishing the communication path (S20), the mobile terminal 1 stores information (patient ID, drug information, medication conditions) stored in the storage unit 23. Is transmitted to the control device 4.

Moreover, in this embodiment, the management server 7 which collates a patient and a chemical | medical agent is further provided.

  The management server 7 includes a computer 8 and a transceiver 9 similar to the transceiver 3 described in FIG. It is assumed that the electrode 903 and the insulating film 904 (hereinafter referred to as “electrodes 903”) of the transceiver 9 are connected to the transceiver body by a cable or the like and are installed at predetermined positions on the floor. The computer 8 includes a transmission unit 81, a collation unit 82, and a database 83 (third storage unit). The transmission unit 81 transmits the verification result to the control device 4 using the transceiver 9. The collation unit 82 refers to the database 83 and collates information received from the mobile terminal 1 and the control device 4. The database 83 stores a patient ID (ID01), drug information (ID12), medication conditions (ID13), doctor ID (ID05), and the like for each patient carrying the portable terminal 1. .

  The portable terminal 1 of this embodiment has the computer 2 and the transceiver 3 similarly to the portable terminal 1 (refer FIG. 2) of 1st Embodiment, and the computer of this embodiment does not have the collation part 22. FIG. The storage unit 23 is different from the portable terminal 1 of the first embodiment in that only the patient ID is stored.

  Further, the control device 4 of the present embodiment has a computer 5 and a transceiver 6 as in the case of the control device 4 (see FIG. 4) of the first embodiment, and the computer of the present embodiment has a matching unit 52. Instead, the storage unit 23 is different from the control device 4 of the first embodiment in that only information related to medicines (medicine information, medication conditions) is stored.

Contact the management server 7 at the same time). Thereby, the 1st communication path between the portable terminal 1 and the management server 7 is established via the nurse's human body which is an electric field transmission medium, and the transmission part of the portable terminal 1 is the first communication path. The patient ID (ID01) memorize | stored in the memory | storage part 23 is transmitted to the management server 7 via (S41).

  Further, when the nurse stands on the electrode 903 and the like and contacts the control device 4 (that is, the control device 4 and the management server 7 are simultaneously contacted), the human body of the nurse as an electric field transmission medium is obtained. The second communication path between the control device 4 and the management server 7 is established via When this second communication path is established, the transmission unit of the control device 4 transmits drug information and administration conditions (ID12, ID13) of the instilled drug to be administered to the patient to the management server 7 (S42).

  The collation unit 82 of the management server 7 collates the information received from the mobile terminal 1 and the control device 4 with reference to the database 83 and sends the collation result (OK / NG) to the control device 4 via the second communication path. (S43). In other words, the collation unit 82 outputs an OK message to the control device 4 that the collation is successful if the combination of the received information exists in the database 83, and fails in collation if the received combination of information does not exist. As a result, an NG message is output to the control device 4. In addition, when collation fails, the collation part 82 is good also as transmitting the alert of an inquiry with respect to the doctor memorize | stored in the database 83. FIG.

  When the OK message is received, the control unit 53 of the control device 4 outputs an infusion start instruction including a medication condition (flow rate measurement or the like) registered in the storage unit 54 to the flow meter 10. When receiving a drip start instruction, the flow meter 10 sets the specified medication conditions and starts the drip. On the other hand, when the NG message is received, the control unit 53 stops the subsequent processing and performs error processing (output of an alarm, an error message, etc.).

  In the medication control system of the second embodiment described above, similarly to the first embodiment, using the electric field communication that transmits and receives information via the electric field transmission medium, misidentification is prevented, and more easily, In addition, a more convenient collation system can be realized. That is, in this embodiment, the mobile terminal 1 and the control device 4 transmit information related to the patient and information related to the medicine of the flow meter to the management server 7, and the management server 7 refers to the database and receives them. Since the verification of the information is performed, it is possible to prevent a medical error (erroneous medication) that administers the wrong medicine to the patient.

  In the present embodiment, information is transmitted and received between the portable terminal 1 and the management server 7 only when the nurse contacts the patient and the electrode 903 of the management server 7 at the same time. Information is transmitted and received between the control device 4 and the management server 7 only by contacting the device 4 and the electrodes 903 of the management server 7 simultaneously.

  In such a driving posture detection system, when the user holds the handle and is in a safe driving posture while sitting on the saddle, the user's human body that is an electric field transmission medium is interposed between the transmitter 61 and the receiver 63. Thus, the receiver 63 can receive a signal transmitted from the transmitter 61. On the other hand, when the user takes a dangerous posture such as releasing his hand from the steering wheel or standing up from the saddle during driving, the communication path is disconnected, and the receiver 63 cannot receive the signal transmitted by the transmitter. The detector of the receiver 63 monitors the signal from the transmitter 61, detects that the signal has been interrupted, and outputs a warning (alarm).

  In the driving posture detection system of the present embodiment, a warning is issued when driving in a dangerous posture such as releasing the handle or standing up from the saddle during driving. The user can be prompted.

<Fifth Embodiment>
The fifth embodiment of the present invention will be described below with reference to the drawings.

  FIG. 9 is an explanatory diagram for explaining an immobilizer system according to a fifth embodiment of the present invention. The immobilizer prevents the vehicle from being stolen by electronic key verification. The immobilizer system according to the present embodiment enables the vehicle to start when a legitimate user (driving permitter) having the portable transmitter 64 sits in the driver's seat, and does not have the portable transmitter 64 (unauthorized driving). When the vehicle is seated in the driver's seat, the vehicle is started and stopped and a warning is output.

  FIG. 9 shows an example in which the immobilizer system is applied to a motorcycle. FIG. 9A shows the case of a driving authorized person who has the portable transmitter 64, and FIG. 9B shows the case of a driving non-permitted person who does not have the portable transmitter 64.

  As shown in the figure, the transmitter 61 is attached to the handle portion, and the receiver 63 is attached to the saddle portion. The authorized person has a portable transmitter 64. The transmitter 61 and the portable transmitter 64 use the electric field signal detection technology (transmission part) of the transceivers 3 and 3B of FIG. 2 or FIG. 3, and apply an electric field based on information to be transmitted to a living body that is an electric field transmission medium. Information is transmitted using the induced electric field. The transmitter 61 includes a transmitter that constantly transmits the first key information (ID1) at a predetermined timing. The portable transmitter 64 has a transmitter that constantly transmits the second key information (ID2) at a predetermined timing.

  The receiver 63 uses the electric field signal detection technology (reception part) of the transceivers 3 and 3B of FIG. 2 or FIG. 3, and receives information using an electric field induced in a living body as an electric field transmission medium. is there. It is assumed that an electrode (including an insulating film) 62 of the receiver 63 is embedded in a saddle (seat). In addition, the receiver 63 of the present embodiment collates the key information received from the transmitter 61 and the portable transmitter 64 with the key information (ID1, ID2) stored in the storage unit of the receiver 63. The motorcycle can be started only when they match, and when the two do not match, start / stop and warning output are performed.

  In FIG. 9A, the driving authorized person who has the portable transmitter 64 sits on the saddle, so that the second key information (ID2) is transmitted to the receiver 63 via the driver's human body. Further, when the driver permitter sits on the saddle and further grips the steering wheel, the first key information (ID1) is transmitted to the receiver 63. The receiver 63 collates the received first and second key information with the key information stored in the receiver 63, and sets the motorcycle in a state where it can be activated because they match.

  In FIG. 9B, when a non-driving person who does not have the portable transmitter 64 sits on the saddle and further grips the handle, the first key information (ID1) is transmitted to the receiver 63. However, since the non-driving person does not have the portable transmitter 64, the second key information (ID2) is not transmitted to the receiver 63. The receiver 63 collates the received first key information with the key information stored in the receiver 63. However, since there is no second key information, the start and stop of the motorcycle and warning output are performed. Do.

  In this embodiment, since the operation permitter who has the portable transmitter 64 sits on the saddle and the electronic key is collated only by grasping the handle, the trouble and time of the operation of the driver are eliminated, and the convenience is improved. can do.

  Note that the immobilizer system of the present embodiment can also be applied to a four-wheeled vehicle. Further, the immobilizer system of the present embodiment may be combined with the driving posture detection system of the third embodiment.

  While the embodiments of the present invention have been described above, various modifications and changes can be made to the embodiments of the present invention without departing from the spirit of the present invention.
