[0014] Problems to be solved by the invention

[0015] In order to perform secure short-range wireless communication between the measuring device and the information terminal, it is necessary to pair the measuring device with the information terminal. Pairing refers to the process of sharing the encrypted information used in short-range wireless communication between the measuring device and the information terminal. If the measuring device is allowed to pair with the information terminal for a long time, it may be paired with an unexpected information terminal, causing concerns in terms of security.

[0016] An object of the present invention is to provide a measurement device, an information terminal, and an operation program of the information terminal that can easily and safely perform pairing.

[0017] Solutions for solving problems

[0018] The above-mentioned problems can be solved by the following configurations. It should be noted that, although corresponding components and the like in the following embodiments are shown in brackets, the present invention is not limited thereto. (1)

[0020] A measuring device (sphygmomanometer 10) includes a short-range wireless communication unit (communication unit 12), a display unit (display unit 15), and a processor (processor 11), wherein:

[0021] The processor performs the following processing:

[0022] When the first operation (short press of the measurement start button 14A) is detected, first control is performed to transmit first information including a first time (20 seconds or 0 seconds) from the short-distance wireless communication unit (step S5);

[0023] performing a second control to display the first time on the display unit and to change the first time displayed on the display unit as time passes (step S6); and

[0024] When a second operation (a short press of the measurement start button 14A) is detected during the period from when the first time is displayed on the display unit to when the time displayed on the display unit reaches a specified value (0 seconds or 20 seconds), a transition is made to a pairing mode, which is a mode that can perform processing of sharing encrypted information for encrypted communication via short-range wireless communication with an information terminal.

[0025] If it is configured as (1), the user can switch the measuring device to the pairing mode only by performing the first operation and the second operation, so that the encrypted information can be easily shared with the information terminal. In addition, by performing the second operation during the period until the time displayed on the display reaches a predetermined value, the measuring device can be switched to the pairing mode, so that the measuring device will not always be in the pairing mode, and the sharing of encrypted information with unintended information terminals can be prevented, thereby improving security. In addition, the pairing mode will not be switched only by the first operation, so the pairing mode can be prevented from being switched to the pairing mode due to an erroneous operation. (2)

[0027] The measuring device according to (1), wherein:

[0028] The measuring device comprises a measuring sensor,

[0029] The first operation is an operation to start the operation of the measurement sensor.

[0031] If it is configured as (2), when the first operation is performed and the measurement result is obtained normally, the first control and the second control are not performed, so the first control and the second control can be appropriately performed, and power saving can be achieved. In addition, the operation for switching to the pairing mode can be made the same as the operation performed during normal measurement, so it is possible to switch to the pairing mode without hesitation. (3)

[0034] The second operation is the same as the first operation.

[0035] If it is configured as (3), it is possible to switch to pairing mode by performing the same operation twice, and it is easier to share encrypted information with the information terminal. By setting the first operation and the second operation as operations required by the measuring device, it is also easy to change to the first control and the second control in the existing measuring device, and it is easy to seek functional improvement through firmware update, etc. (4)

[0037] The measuring device according to any one of (1) to (3), wherein:

[0040] The measuring device according to any one of (1) to (4), wherein:

[0041] The processor broadcasts the first information.

[0042] According to (5), even when communication with the information terminal is not established, the first information can be sent to the information terminal, and for example, the first time included in the first information can be displayed on the information terminal. The user can identify the pair for sharing encrypted information by the relationship between the time displayed on the measuring device and the time displayed on the information terminal, thereby preventing the establishment of a communication connection or the sharing of encrypted information with an unintended information terminal. (6)

[0044] An information terminal (smartphone 20) includes a short-range wireless communication unit (communication unit 22), a display unit (display unit 25) and a processor (processor 21), wherein:

[0045] The processor performs the following processing:

[0046] A third control is performed to display information indicating that a first operation (short press of the measurement start button 14A) is performed on the measurement device (the sphygmomanometer 10 ) on the display unit (step S11 );

[0047] In the state where the third control is performed, a fourth control is performed (step S12), wherein the first information including the first time (20 seconds or 0 seconds) transmitted from the measurement device is acquired, the first time is displayed on the display unit, the first time displayed on the display unit is changed as time passes, and information indicating that a second operation (short press of the measurement start button 14A) is performed on the measurement device is displayed on the display unit; and

[0048] A process is performed (step S31) of sharing encryption information for encrypted communication by short-range wireless communication with a measuring device that transmits a broadcast signal during a period from when the display unit displays the first time until the time displayed on the display unit reaches a specified value (0 seconds or 20 seconds).

[0049] According to (6), the user can share the encrypted information between the measuring device and the information terminal only by performing the first operation and the second operation on the measuring device according to the information displayed on the display unit. In addition, the encrypted information is shared with the measuring device that transmits the broadcast signal during the period until the time displayed on the display unit reaches the specified value, thereby preventing the encrypted information from being shared with unintended measuring devices, thereby improving security. (7)

[0051] The information terminal according to (6), wherein:

[0052] The first operation is an operation for starting the operation of the measurement sensor of the measurement device.

[0053] According to the configuration of (7), encrypted information can be shared with the measuring device by operating the measuring device in the normal measurement according to the information displayed on the display unit. Therefore, encrypted information can be easily shared between the measuring device and the information terminal. (8)

[0055] The information terminal according to (6) or (7), wherein:

[0056] The second operation is the same as the first operation.

[0057] According to (8), encrypted information can be shared with the measuring device by performing the same operation as that performed during normal measurement on the measuring device twice according to the information displayed on the display unit.

[0065] Figure 1 It is a schematic diagram showing a schematic configuration of the management system 100 .

[0066] Figure 2 This is a sequence diagram showing the processing procedure when the blood pressure monitor 10 and the smartphone 20 are paired. DETAILED DESCRIPTION

[0067] (Overview of management system including measurement device and information terminal of this method)

[0068] The processor of the information terminal performs a third control to display information indicating that a first operation is performed on the measuring device. When the user performs a first operation on the measuring device according to the information displayed by the third control, the processor of the measuring device performs a first control to send first information including a first time, and performs a second control to display the first time and change the first time as time passes. When the first information sent from the measuring device is acquired, the processor of the information terminal performs a fourth control, which is a control to display the first time included in the first information, change the first time as time passes, and display information indicating that a second operation is performed on the measuring device. When the user performs a second operation on the measuring device according to the information displayed by the fourth control, the processor of the measuring device switches to a pairing mode, which is a mode in which a process of sharing encrypted information for encrypted communication with the information terminal can be performed. When switching to the pairing mode, the measuring device sends a broadcast signal, and the information terminal that receives the broadcast signal establishes a communication connection with the measuring device, and shares encrypted information with the measuring device.

[0069] The above method enables easy and secure pairing between the measurement device and the information terminal.

[0070] Hereinafter, a configuration example of a management system 100 including a measurement device and an information terminal according to this embodiment will be described.

[0071] (System Configuration)

[0072] Figure 1 It is a schematic diagram showing the general structure of the management system 100. The management system 100 is a system that includes a sphygmomanometer 10 as an example of a measuring device and a smartphone 20 as an example of an information terminal, and is used to manage the measurement data, programs, etc. of the sphygmomanometer 10 through the smartphone 20. The sphygmomanometer 10 and the smartphone 20 are configured to communicate through short-range wireless communication. The method of short-range wireless communication is not particularly limited, and for example, methods such as Wi-Fi, ANT (Adaptive Network Topology), Bluetooth (registered trademark), or infrared communication can be used. In the following, the method of short-range wireless communication is described as Bluetooth (registered trademark). In the following, the owner of both the sphygmomanometer 10 and the smartphone 20 is recorded as a user.

[0073] (Measurement device)

[0074] The sphygmomanometer 10 includes a processor 11 , a communication unit 12 , a storage unit 13 , an operation unit 14 , a display unit 15 , and a sensor unit 16 .

[0075] The sensor unit 16 includes a pressure sensor disposed on the cuff portion of the sphygmomanometer 10 as a measurement sensor, and the pressure sensor detects a pulse wave from the user's blood vessels at an appropriate cuff pressure. In the sphygmomanometer 10, blood pressure information including the highest blood pressure, the lowest blood pressure, and the pulse can be calculated based on the pulse wave detected by the sensor unit 16.

[0076] The communication unit 12 is a communication interface for performing short-range wireless communication, and includes a communication antenna and various circuits.

[0077] The storage unit 13 is configured to include a non-transitory storage medium such as a flash memory in addition to a working memory such as a RAM (Random Access Memory). Various information such as measured blood pressure information is stored in the storage medium.

[0078] The operation unit 14 is an input unit such as a button or a touch panel that receives input from the user, and receives various operations such as turning on / off the power, starting the measurement of blood pressure information, and selecting items performed by the user. The operation unit 14 includes a measurement start button 14A for instructing the start of the measurement of blood pressure information and a communication button 14B for operating the communication unit 12 (enabling short-range wireless communication). The measurement start button 14A and the communication button 14B may be hardware buttons or software buttons displayed on the display unit 15 equipped with a touch panel.

[0079] The display unit 15 is constituted by a display such as an organic EL (electro-luminescence) display or a liquid crystal display, and displays measured blood pressure information and the like.

[0080] The processor 11 controls all parts of the sphygmomanometer 10. The processor 11 is a CPU (Central Processing Unit) which is a general-purpose processor that executes software (programs) to perform various functions, a programmable logic device (PLD) such as an FPGA (Field Programmable Gate Array) which is a processor whose circuit structure can be changed after manufacturing, or a dedicated electrical circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit structure specially designed for performing specific processing. The processor 11 can be composed of one processor or a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, CPUs and FPGAs). For example, the processor 11 can also be configured to include a processor that controls communication using the communication unit 12 and a processor that performs various controls other than the communication. More specifically, the hardware structure of the processor 11 is an electrical circuit (circuitry) that combines circuit elements such as semiconductor elements.

[0081] When the pressing of the measurement start button 14A included in the operation unit 14 is detected, the processor 11 receives the instruction to start the measurement, supplies air to the cuff, and calculates the blood pressure information based on the pulse wave detected by the sensor unit 16 at an appropriate cuff pressure. Then, the processor 11 displays the calculated blood pressure information on the display unit 15. The processor 11 controls each component of the sphygmomanometer 10 in a manner that performs processing corresponding to the user's operation performed via the operation unit 14. The act of pressing the measurement start button 14A constitutes an operation to start the operation of the sensor unit 16. The measurement start button 14A is not pressed continuously for a specified time (performing a so-called long press operation), but can be input to the processor 11 by pressing it only once for a short period of time (performing a so-called short press operation).

[0082] When detecting the pressing of the communication button 14B included in the operation unit 14, the processor 11 activates the communication unit 12. The pressing operation of the communication button 14B required for activating the communication unit 12 is, for example, a long pressing operation.

[0083] exist Figure 1In the embodiment of the present invention, the sphygmomanometer 10 is shown as an example of a measuring device, but the sphygmomanometer 10 may be replaced by a weight scale, a body composition analyzer, a pulse meter, a heart rate meter, a thermometer, a blood glucose meter, a pulse oximeter, or an activity meter. In any of these measuring devices, the sensor unit 16 also includes various measuring sensors (pressure sensor, pulse wave sensor, blood glucose sensor, photoelectric sensor, temperature sensor, or acceleration sensor, etc.) for measuring the physical quantity of the measuring object. In the case where the measuring device is a biological information measuring device, when the pressing of the measurement start button 14A included in the operation unit 14 is detected, the processor 11 operates the measuring sensor (pressure sensor, pulse wave sensor, blood glucose sensor, photoelectric sensor, or temperature sensor, etc.) included in the sensor unit 16 to measure the biological information. In the case where the measuring device is an activity measurement device, when the power button for turning on the power of the device is pressed instead of pressing the measurement start button 14A, the processor 11 operates the measuring sensor (acceleration sensor, angular velocity sensor, etc.) included in the sensor unit 16 to measure the activity.

[0084] (Information Terminal)

[0085] The smartphone 20 includes a processor 21 , a communication unit 22 , a storage unit 23 , an operation unit 24 , and a display unit 25 .

[0086] The communication unit 22 is a communication interface for performing short-distance wireless communication, and includes a communication antenna and various circuits.

[0087] The storage unit 23 is configured to include a non-transitory storage medium such as a flash memory in addition to a working memory such as a RAM. Various information including application programs (operating programs of the information terminal, management applications described later) are stored in the storage medium.

[0088] The operation unit 24 is an input unit such as buttons or a touch panel for receiving input from the user, and receives various operations from the user.

[0089] The display unit 25 is constituted by a display such as an organic EL display or a liquid crystal display.

[0090] The processor 21 centrally controls each unit of the smartphone 20. The processor 21 is composed of one or more processors, similarly to the processor 11. The processor 21 executes various programs stored in the storage unit 23 to perform processing corresponding to the programs.

[0091] (How to pair the blood pressure monitor with a smartphone)

[0092] Next, a method for pairing the blood pressure monitor 10 and the smartphone 20 will be described. Figure 22 is a timing chart showing the processing procedure when the blood pressure monitor 10 is paired with the smartphone 20. Figure 2 The right end of shows an example of a message displayed on the display unit 25 of the smartphone 20. It is assumed that a management application for managing blood pressure information is installed and stored in advance in the storage unit 23 of the smartphone 20.

[0093] The user operates the smartphone 20 to start the management application. When the management application is started, the processor 21 of the smartphone 20 displays the device registration screen on the display unit 25 (step S11). In addition, the processor 21 starts scanning by the communication unit 22. Scanning means that the communication unit 22 enters a receiving state to obtain information about surrounding devices. In step S11, the processor 21 of the smartphone 20 includes information indicating that a first operation is to be performed on the sphygmomanometer 10 in the device registration screen and displays it on the display unit 25. The first operation is, for example, an operation to start the operation of the sensor unit 16 included in the sphygmomanometer 10, specifically, "pressing the measurement start button 14A".

[0094] like Figure 2 As shown, the device registration screen displayed in step S11 includes a message such as "Please press the measurement start button of the blood pressure monitor". When confirming the message, the user prepares the blood pressure monitor 10 to be paired with the smartphone 20, turns on the power of the blood pressure monitor 10, and presses the measurement start button 14A included in the operation unit 14 of the blood pressure monitor 10. It should be noted that here, the user does not perform the usual blood pressure information measurement operation such as wrapping the cuff around the arm or wrist and then pressing the measurement start button 14A, but presses the measurement start button 14A without wrapping the cuff around the arm or wrist.

[0095] When the pressing of the measurement start button 14A is detected (step S1), the processor 11 of the sphygmomanometer 10 performs measurement control of the blood pressure information (step S2). The measurement control includes: air supply and exhaust control of the cuff, detection of the cuff pressure by the pressure sensor, and processing of deriving the blood pressure information based on the pressure information detected by the pressure sensor. When the measurement start button 14A is pressed in a state where the cuff is not wrapped around the arm or wrist, the output of the pressure sensor becomes a value that is far different from the state where the cuff is wrapped around the arm or wrist. Therefore, when the output of the pressure sensor indicates an abnormal value during the execution of the measurement control, the processor 21 of the smartphone 20 determines that the blood pressure information cannot be measured (step S3), and displays information indicating a measurement error on the display unit 25.

[0096] When it is determined in step S3 that the blood pressure information cannot be measured, the processor 11 of the sphygmomanometer 10 switches to a waiting mode for switching to a pairing mode (step S4). The pairing mode is a mode in which processing for sharing encrypted information for encrypted communication via short-range wireless communication with an information terminal can be performed. It should be noted that, when it is determined that the blood pressure information can be measured, the processor 11 of the sphygmomanometer 10 stores the derived blood pressure information in the storage unit 13 and displays it on the display unit 15, and ends the processing. That is, after the processor 11 of the sphygmomanometer 10 detects the pressing of the measurement start button 14A, it switches to the waiting mode only when it is determined that the blood pressure information cannot be measured.

[0097] The processor 11 of the sphygmomanometer 10 starts the communication unit 12 in the waiting mode, and starts the notification by the communication unit 12 (step S5). The notification refers to the broadcast of a packet including various information. Hereinafter, the signal sent by the notification is also recorded as a broadcast signal. In step S5, a packet including the first information is broadcasted periodically, and the first information includes mode information indicating that the operation is being performed in the waiting mode and a first time as the time of continuing the waiting mode. In addition, the processor 11 of the sphygmomanometer 10 performs the following control (step S6): the above-mentioned first time and mode information are displayed on the display unit 15, and the above-mentioned first time displayed on the display unit 15 is reduced as time passes. The first time is an arbitrarily determined time, and as an example, it is 20 seconds. Therefore, in step S6, an image indicating the waiting mode and the text "20 seconds" are displayed on the display unit 15 of the sphygmomanometer 10, and the text of the number of seconds in the display is reduced by 1 second every time 1 second passes to update the time display, and the time countdown is performed.

[0098] When the first information broadcasted from the sphygmomanometer 10 by the process of step S5 is acquired via the communication unit 22, the processor 21 of the smartphone 20 performs the following control (step S12): the first time and mode information included in the first information is displayed on the display unit 25, the first time displayed on the display unit 25 is decreased as time passes, and information indicating that the second operation is to be performed on the sphygmomanometer 10 is displayed on the display unit 25. At this time, it is preferable that, when the first information is broadcasted from a plurality of devices, the processor 21 of the smartphone 20 selects the device with the largest radio wave strength of the broadcast signal, acquires the first information from the selected device, and displays the first time and mode information on the display unit 25. The second operation is preferably the same operation as the first operation (pressing the measurement start button 14A), but may be an operation different from the first operation (for example, a short press of the communication button 14B, etc.).

[0099] Through the processing of step S12, Figure 2As shown, a message such as "Please press the measurement start button of the blood pressure monitor within the displayed time [20 seconds]" is displayed on the display unit 25. Every time 1 second passes, the text of the seconds displayed is reduced by 1 second to update the time display and count down the time.

[0100] The processing of step S6 in the sphygmomanometer 10 and the processing of step S12 in the smartphone 20 are performed with almost no time difference. Therefore, the time displayed on the display unit 15 of the sphygmomanometer 10 and the time displayed on the display unit 25 of the smartphone 20 are updated and decreased at the same timing starting from "20 seconds" as the initial value. By synchronizing the time displayed on the display unit 15 of the sphygmomanometer 10 and the time displayed on the display unit 25 of the smartphone 20, the user can clearly identify the sphygmomanometer 10 to be operated.

[0101] After confirming the message displayed on the smartphone 20 in the process of step S12, the user performs a second operation on the sphygmomanometer 10 (here, pressing the measurement start button 14A) until the displayed number of seconds reaches 0 seconds. When the pressing of the measurement start button 14A is detected (step S7), the processor 11 of the sphygmomanometer 10, which is operating in the waiting mode, does not perform the measurement control of the blood pressure information and switches to the pairing mode (step S8). When switching to the pairing mode, the processor 11 of the sphygmomanometer 10 starts the notification by the communication unit 12 (step S9). In step S9, a packet including information required to establish a communication connection realized by short-range wireless communication (such as individual identification information of the sphygmomanometer 10) is broadcasted periodically.

[0102] When the broadcast signal transmitted from the sphygmomanometer 10 in the process of step S9 is acquired, the processor 21 of the smartphone 20 makes a connection request to the sphygmomanometer 10 via the communication unit 22. When the processor 11 of the sphygmomanometer 10 responds to the connection request via the communication unit 12, a communication connection is established between the sphygmomanometer 10 and the smartphone 20 by short-range wireless communication (step S30).

[0103] The method by which the smartphone 20 identifies the other party making the connection request is not particularly limited. For example, the processor 21 of the smartphone 20 may identify the device with the strongest broadcast signal as the other party, or may display a list of connection destination candidates and identify the device selected by the user as the other party.

[0104] When the communication connection between the smartphone 20 and the sphygmomanometer 10 is established, mutual authentication between the smartphone 20 and the sphygmomanometer 10 is performed by a prescribed method. When mutual authentication is completed, encryption information (such as encryption keys, etc.) used for encrypted communication through short-range wireless communication is shared between the smartphone 20 and the sphygmomanometer 10 (step S31). Sharing of encryption information means that the processor 11 of the sphygmomanometer 10 generates encryption information, stores the encryption information in the storage unit 13 and sends it to the smartphone 20, and the smartphone 20 stores the encryption information in the storage unit 23. It should be noted that sharing of encryption information can also be performed in the following manner: the processor 21 of the smartphone 20 generates encryption information, stores the encryption information in the storage unit 23 and sends it to the sphygmomanometer 10, and the sphygmomanometer 10 stores the encryption information in the storage unit 13.

[0105] After step S31, the processor 21 of the smartphone 20 causes the display unit 25 to display a message indicating that pairing has been completed, such as "Registration of the blood pressure monitor has been completed." Then, the processor 21 of the smartphone 20 cuts off the communication connection with the blood pressure monitor 10. After that, secure communication using encrypted information can be performed between the smartphone 20 and the blood pressure monitor 10. For example, when the measurement start button 14A is pressed while the cuff is wrapped around the arm or wrist, the blood pressure information is exported and stored in the storage unit 13. Then, the processor 11 of the blood pressure monitor 10 starts the communication unit 12, establishes a connection with the smartphone 20 that has shared the encrypted information, encrypts the blood pressure information, and sends it to the smartphone 20.

[0106] As described above, according to the management system 100, the user can switch the blood pressure meter 10 to the pairing mode only by sequentially performing the first operation and the second operation on the blood pressure meter 10 according to the information displayed on the smartphone 20. After switching to the pairing mode, the blood pressure meter 10 and the smartphone 20 share encrypted information through the same process as before. Compared with the configuration in which the blood pressure meter 10 can be switched to the pairing mode by long pressing of a specific button, operation of a button provided at a difficult-to-operate position such as the bottom surface of the device, etc., in the management system 100, the blood pressure meter 10 can be switched to the pairing mode by the first operation and the second operation which are simple operations. Therefore, the blood pressure meter 10 and the smartphone 20 can be easily paired. In addition, by performing the second operation during the period until the time displayed on the display unit 15 and the display unit 25 reaches a predetermined value (in the above example, "0 seconds") (that is, during the duration of the waiting mode), the blood pressure meter 10 can be switched to the pairing mode, so that the blood pressure meter 10 will not always be in the pairing mode, and sharing of encrypted information with unintended information terminals can be prevented, thereby improving security.

[0107] Furthermore, the processor 11 of the sphygmomanometer 10 does not switch to the pairing mode when only the first operation is performed, thereby preventing the switch to the pairing mode due to an erroneous operation. Furthermore, the processor 11 of the sphygmomanometer 10 does not switch to the waiting mode unconditionally when the first operation is performed, but switches to the waiting mode when it is determined that the blood pressure information cannot be measured. Therefore, during normal blood pressure measurement, the processor 11 does not switch to the waiting mode and the pairing mode, and the processor 11 can be operated in the waiting mode and the pairing mode only when necessary. It should be noted that it may be possible to set the processor 11 of the sphygmomanometer 10 not to switch to the waiting mode even when the first operation is performed, when the processing for sharing the encrypted information has been completed. That is, it may also be possible that the processor 11 switches to the waiting mode when the processing for sharing the encrypted information has been completed and the first operation is detected (when Figure 2 In the case where the first operation is detected after the processing of step S31), the blood pressure measurement process is started without executing the control of transferring to the waiting mode and the pairing mode. By setting it in this way, it is possible to prevent the transition to the waiting mode and the pairing mode when the first operation is performed by mistake, and to save power, etc.

[0108] In the management system 100, by making the first operation and the second operation the same, pairing can be easily and safely performed even when the number of operating elements (buttons, etc.) included in the operating unit 14 mounted on the blood pressure meter 10 is limited. In particular, by making the first operation and the second operation respectively the operations required by the blood pressure meter 10 (operation to start the measurement of blood pressure information), it is possible to perform pairing in a plurality of existing blood pressure meters 10. Figure 2 The processing shown does not require modification of the hardware of the sphygmomanometer 10 , and can reduce the construction cost of the management system 100 .

[0109] In the above description, the first operation is the pressing of the measurement start button 14A, but the pressing (short press) of the communication button 14B may be set as the first operation, or the pressing of the power button (a button for turning on the power of the sphygmomanometer 10) not shown in the figure may be set as the first operation. That is, in step S11, the operation of indicating the communication button 14B (or the power button) may be replaced by the operation of indicating the measurement start button 14A, and in step S1, when the pressing of the communication button 14B (or the power button) is detected, the processing from step S4 to step S6 is performed. In this case, the processing of step S2 and step S3 is omitted, and the following action may be changed: in step S12, the information indicating the operation of the communication button 14B (or the measurement start button 14A) is displayed on the display unit 25, and in step S7, when the pressing of the communication button 14B (or the measurement start button 14A) is detected, the pairing mode is changed.

[0110] In the above description, in step S6 and step S12, it is set to reduce the first time after the first time is displayed, but it can also be configured to increase the first time after the first time is displayed. For example, the first time can also be set to "0 seconds", and in step S6 and step S12, control is performed to increase the displayed number of seconds by "1" every time 1 second passes. In this case, for example, a message such as "Please press the measurement start button of the sphygmomanometer 10 until the displayed number of seconds reaches 20 seconds. [0 seconds]" is displayed on the display unit 15 and the display unit 25.

It is obvious that those skilled in the art can think of various variations or modifications within the scope described in the claims, and understand that these variations or modifications also belong to the technical scope of the present invention. In addition, the various constituent elements in the above embodiments can also be arbitrarily combined within the scope of the gist of the invention.
