  • the processor 21 of the smartphone 20 Upon acquiring the broadcast signal transmitted from the blood pressure monitor 10 in the process of step S9, the processor 21 of the smartphone 20 issues a connection request to the blood pressure monitor 10 via the communication unit 22.
  • the processor 11 of the blood pressure monitor 10 responds to this connection request via the communication unit 12, a communication connection is established between the blood pressure monitor 10 and the smartphone 20 by short-range wireless communication (step S30).
  • the method by which the smartphone 20 identifies a partner to which a connection request is to be made is not particularly limited.
  • the processor 21 of the smartphone 20 may identify the device with the highest radio wave strength of the broadcast signal as the connection partner, or may display a list of connection candidate destinations and identify a device selected by the user from the list as the connection partner.
  • Encrypted information for example, an encryption key, etc.
  • Sharing of encrypted information means that the processor 11 of the blood pressure monitor 10 generates encrypted information, stores the encrypted information in the storage unit 13 and transmits it to the smartphone 20, and the smartphone 20 stores the encrypted information in the storage unit. 23.
  • the processor 21 of the smartphone 20 generates encrypted information, stores the encrypted information in the storage unit 23 and transmits it to the blood pressure monitor 10, and the blood pressure monitor 10 stores the encrypted information in the storage unit 13.
  • Encrypted information may also be shared.
  • the processor 21 of the smartphone 20 causes the display unit 25 to display a message indicating that pairing has been completed, such as "Sphygmomanometer registration has been completed.”
  • the processor 21 of the smartphone 20 then disconnects the communication connection with the blood pressure monitor 10. From then on, secure communication using encrypted information is possible between the smartphone 20 and the blood pressure monitor 10. For example, when the measurement start button 14A is pressed with the cuff wrapped around the arm or wrist, blood pressure information is derived and stored in the storage unit 13.
  • the processor 11 of the blood pressure monitor 10 then activates the communication unit 12, establishes a connection with the smartphone 20 with which the encrypted information has been shared, and encrypts the blood pressure information and transmits it to the smartphone 20.
  • the user can pair the blood pressure monitor 10 by simply sequentially performing the first and second operations on the blood pressure monitor 10 according to the information displayed on the smartphone 20. mode. After shifting to the pairing mode, encrypted information is shared between the blood pressure monitor 10 and the smartphone 20 through the same process as before.
  • the management system 100 The blood pressure monitor 10 can be shifted to the pairing mode by a first operation and a second operation, which are simple operations. Therefore, it becomes possible to easily pair the blood pressure monitor 10 and the smartphone 20.
  • the processor 11 of the blood pressure monitor 10 since the processor 11 of the blood pressure monitor 10 does not shift to pairing mode just by performing the first operation, it is possible to prevent shifting to pairing mode due to an erroneous operation. Furthermore, the processor 11 of the blood pressure monitor 10 does not unconditionally shift to standby mode when the first operation is performed, but shifts to standby mode when it is determined that blood pressure information cannot be measured. Therefore, during normal blood pressure measurement, the processor 11 does not shift to the standby mode and pairing mode, and the processor 11 can be operated in the standby mode and pairing mode only when necessary. Note that if the processor 11 of the blood pressure monitor 10 has already executed the process of sharing the encrypted information, the processor 11 may not shift to the standby mode even if the first operation is performed.
  • the blood pressure measurement process may be started without executing the control for transitioning to standby mode and pairing mode. By doing so, it is possible to prevent transition to standby mode and pairing mode even if the first operation is performed by mistake, and to save power.
  • the management system 100 by making the first operation and the second operation the same, even if there is a limit to the number of operators (buttons, etc.) included in the operation unit 14 installed in the blood pressure monitor 10, Pairing can be performed easily and safely.
  • many existing blood pressure monitors 10 can execute the process shown in FIG. This makes it possible to eliminate the need to modify the hardware of the blood pressure monitor 10 and reduce the construction cost of the management system 100.
  • the first operation is a press of the measurement start button 14A, but the first operation may also be a press (short press) of the communication button 14B, or a power button (not shown) (to turn on the power of the blood pressure monitor 10).
  • the first operation may be a press of a button for That is, in step S11, an instruction is given to operate the communication button 14B (or power button) instead of the measurement start button 14A, and in step S1, if pressing of the communication button 14B (or power button) is detected, step S4
