  FIG. 5 is a block diagram of the measurement system 10. The blood glucose meter 14 includes a display unit 74, an operation unit 76, a measurement unit 100, a storage unit 102, a control unit 104, and a communication unit (measuring device side communication unit) 106. Although not shown, the measuring unit 100 includes a light emitting unit that irradiates the test paper 56 of the mounted chip 16 with pulsed light, and a light receiving unit that receives the light reflected by the colored test paper 56, The light receiving signal received by the light receiving unit is converted into a digital value and output to the control unit 104.

  The storage unit 102 stores necessary data and programs. The control unit 104 includes a CPU and a memory, and the CPU functions as the control unit 104 by executing a program stored in the storage unit 102. The control unit 104 calculates a blood glucose level based on the light reception signal sent from the measurement unit 100. In addition, the control unit 104 transmits specific information (for example, the calculated measurement value, the operation information of the operation unit 76, or the guidance information indicating the operation procedure of the blood glucose meter 14) from the communication unit 106.

  The storage case 12 includes a directional speaker 28, a switch 30, a storage unit 110, a control unit 112, and a communication unit (storage case side communication unit) 114. The storage unit 110 stores necessary data such as sound data and a program. The control unit 112 includes a CPU and a memory, and the CPU functions as the control unit 112 by executing a program stored in the storage unit 110. When the storage case 12 is open, the control unit 112 acquires sound data corresponding to the information received by the communication unit 114 from the storage unit 110 and outputs sound based on the acquired sound data from the directional speaker 28. To do. The communication unit 106 and the communication unit 114 can perform wireless communication with each other using, for example, Bluetooth (registered trademark), IrDA (Infrared Data Association), or the like.

  Next, an example of operation | movement of the blood glucose meter 14 of the measurement system 10 is demonstrated according to the flowchart of FIG.

  The control unit 104 determines whether or not the power is turned on (step S1). When the power is supplied from a power source (not shown) by the operation of the power button 76a of the user 36 and the control unit 104 is activated, the control unit 104 determines that the power is turned on.

  If it is determined in step S1 that the power is turned on, the control unit 104 transmits operation information indicating that the power button 76a is operated from the communication unit 106 (step S2). At this time, the control unit 104 may display information indicating that the power is turned on on the display unit 74. For example, a sentence “Power is turned on” may be displayed on the display unit 74.

  Next, the control unit 104 transmits, from the communication unit 106, guidance information that prompts the user to attach the chip 16, which is one of the operation procedures of the blood glucose meter 14 (step S3). At this time, the control unit 104 may display information indicating that the chip 16 is urged to be mounted on the display unit 74. For example, a sentence “Please wear a chip” may be displayed on the display unit 74.

  Next, the control unit 104 determines whether or not the chip 16 is attached (step S4). Whether or not the chip 16 is mounted is determined by determining whether or not the chip 16 is mounted based on a digital value of a light reception signal received by the light receiving unit of the measuring unit 100. When the chip 16 is mounted, the light emitted from the light emitting unit of the measuring unit 100 is reflected by the test paper 56 and enters the light receiving unit, so that the digital value sent from the measuring unit 100 is the threshold value. In the above case, it is determined that the chip 16 is attached.

  If it is determined in step S4 that the chip 16 is not attached, it remains in step S3 until it is attached. At this time, if the chip 16 has not been mounted for a certain time or longer, the control unit 104 may transmit guidance information for prompting the mounting of the chip 16 from the communication unit 106, and information indicating a warning from the communication unit 106. You may send it. Further, the control unit 104 may display information or the like indicating that the chip 16 is to be mounted on the display unit 74.

  If it is determined in step S4 that the chip 16 has been attached, the control unit 104 transmits guidance information that prompts blood spotting, which is one of the operation procedures of the blood glucose meter 14, from the communication unit 106 (step S5). At this time, the control unit 104 may display information indicating that blood is to be spotted on the display unit 74. For example, a sentence “Please deposit blood on the chip” may be displayed on the display unit 74.

  Next, the control unit 104 calculates a blood glucose level based on the digital value sent from the measurement unit 100 after a predetermined time has elapsed (step S6). Here, when blood is spotted on the chip 16 and the test paper 56 absorbs blood, coloration is started by a reaction between glucose in the blood and a reagent impregnated in the test paper 56.

  If the digital value sent from the measuring unit 100 is not included in a predetermined range after a certain time has elapsed, information indicating a measurement error and guidance information for prompting the spotting are transmitted from the communication unit 106. May be. When the digital value sent from the measurement unit 100 is not included in the predetermined range, the test paper 56 is sufficient even if the spotting unit 58 is not spotted or spotted. This is because the blood does not penetrate and blood glucose level cannot be calculated accurately. Of course, the control unit 104 may display information or the like indicating that the display unit 74 prompts spotting.

  Next, when the blood glucose level is calculated, the control unit 104 transmits information indicating the calculated blood glucose level (blood glucose level information) from the communication unit 106 (step S7). At this time, the control unit 104 may display the calculated blood glucose level on the display unit 74.

  Next, an example of operation | movement of the storage case 12 of the measurement system 10 is demonstrated according to the flowchart of FIG.

  When measuring the blood glucose level, the user 36 places the storage case 12 and opens the lid 26 so that the storage case 12 is in the state shown in FIG. Remove from 12.

  Therefore, the control unit 112 first determines whether the storage case 12 is open based on the on / off state of the switch (closed detection unit) 30. Note that when the switch 30 is turned on, power may be supplied from a power source (not shown) and the control unit 112 may be activated. In this case, when activated, the control unit 112 determines that the storage case 12 is open.

  If it is determined in step S1 that the storage case 12 is open, the control unit 112 determines whether the communication unit 114 has received information transmitted from the blood glucose meter 14 (step S22), and step S22. If the communication unit 114 determines that the information from the blood glucose meter 14 is not received, the process returns to step S21.

  On the other hand, when it is determined in step S22 that the communication unit 114 has received information from the blood glucose meter 14, the control unit 112 outputs a sound from the directional speaker 28 based on the received information (step S23). Return to step S21.

  Specifically, the control unit 112 acquires sound data corresponding to the received information from the storage unit 110 and outputs sound based on the sound data from the directional speaker 28. For example, when the operation information of the power button 76a transmitted in step S2 of FIG. 6 is received, the sound data “Power is turned on” corresponding to the operation information is acquired from the storage unit 110. The sound is output from the directional speaker 28. Thereby, the user 36 can recognize that the power source of the blood glucose meter 14 is turned on.

  When the guidance information that prompts the user to attach the chip 16 transmitted in step S3 in FIG. 6 is received, the sound data “Please attach the chip” corresponding to the guidance information is acquired from the storage unit 110, Sound is output from the directional speaker 28. Thereby, the user 36 can recognize mounting | wearing with the chip | tip 16 as a next step.

  When the guidance information prompting the spotting of the blood transmitted in step S5 in FIG. 6 is received, the sound data corresponding to the guidance information “The tip has been attached. Is obtained from the storage unit 110 and the sound is output from the directional speaker 28. Thereby, the user 36 can recognize that blood is spotted on the chip as the next stage.

  When the blood glucose level information (for example, 123) transmitted in step S7 of FIG. 6 is received, sound data (for example, “hyaku”, “niju”, and the like corresponding to the blood glucose level information (measurement value information), and (San's sound data) is acquired from the storage unit 110, and sound is output from the directional speaker 28. Thereby, the user 36 can recognize the measured blood glucose level.

  In this way, since the blood glucose meter 14 is not provided with a speaker, the storage case 12 is provided with a directional speaker 28 and the blood glucose level measured by the blood glucose meter 14 is output from the directional speaker 28. The blood glucose meter 14 can be reduced in size while suppressing the power consumption of the meter 14, and the measured value or the like can be recognized by the user 36 by sound.

  Since the directional speaker 28 outputs a sound based on the operation information of the operation unit 76 and the guidance information indicating the operation procedure of the blood glucose meter 14, the user 36 can confirm what operation has been performed by the sound. At the same time, it is possible to recognize what operation should be performed, and the handling of the blood glucose meter 14 is simplified.

  Further, the directional speaker 28 is provided inside the lid portion 26 so that the directional speaker 28 is directed toward the user 36 (particularly the face of the user 36) when the storage case 12 is opened, and the storage case 12 is opened. When the measuring system 10 is used, the user 36 can be made to recognize the sound, and the surrounding people can hardly hear the sound.

  In the above embodiment, the blood glucose meter 14 that measures blood sugar in body fluid is described as one type of measuring device. However, any device that measures a predetermined component in body fluid other than blood glucose may be used. In this case, the measurement unit 100 has a function of measuring predetermined components in body fluids other than blood sugar. Moreover, although a sound is output according to the received information, a simple sound such as a warning sound or a confirmation sound may be output. In this case, the storage unit 110 stores sound data of sounds (warning sound, confirmation sound, etc.) according to each information.

  As described above, the present invention has been described using the preferred embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
