  As shown in FIGS. 1 and 2, a tip 12 is mounted as a test tool at the tip of the blood glucose meter (component measurement device, medical device) 10a according to the first embodiment. The blood glucose meter 10a is mainly used as a personal use application in which the patient himself operates to measure blood glucose, but of course, the blood glucose meter 10a can also be used as a medical facility application used by a medical worker without special modification. . First, the chip 12 will be described.

  As shown in FIG. 3, the tip 12 includes a bottomed cylindrical base tube 14, a flange 16 protruding radially outward from the base tube 14, a nozzle 18 protruding from the bottom of the base tube 14, and the base tube 14. And a test paper 20 installed on the bottom inner surface. The base tube 14 is provided with a plurality of slits 14a. In the center of the nozzle 18, a straight blood introduction path 24 that communicates from the spotted portion 22 at the tip to the test paper 20 is provided. Examples of the material of the test paper 20 include polyethersulfone. Examples of the reagent impregnated in the test paper 20 include color formers such as glucose oxidase (GOD), peroxidase (POD), 4-aminoantipyrine, and N-ethyl N- (2-hydroxy-3-sulfopropyl). It is done. The reagent may contain a predetermined buffer.

  The blood introduction path 24 is set to have a sufficiently small diameter so that blood is sucked up by capillary action, and introduces the blood in contact with the spotting portion 22 to the test paper 20.

  The chip 12 is a so-called disposable product and is housed in a case 26 (see FIG. 1) as an individual package, and the base end opening of the case 26 is sealed with a film.

  1 and 2, the blood glucose meter 10a according to the first embodiment includes a chip mounting portion 28 to which the chip 12 is mounted, an ejector 30 provided on the upper surface in the vicinity of the chip mounting portion 28, and a central portion on the upper surface.

The blood glucose meter 10a has a slightly elongated shape that can be easily grasped with one hand, and the distal end portion becomes narrower toward the distal end and is bent slightly downward to facilitate the spotting operation.

  The upper surface portion of the blood glucose meter 10a is formed in a flat shape. In addition to displaying the measured blood glucose level, the display 36 can confirm a predetermined input operation and display a maintenance code.

  The operation unit 38 includes a power button 50 for turning on / off the power, a memory call button 52 for calling a measurement value stored in the past, a speaker 54, a playback button 56, and a microphone 58. The speaker 54 outputs information such as a measurement value, which is a blood glucose level measurement result, and medical guidance, operation guidance, and error notification based on the measurement value, and outputs a sound such as a beep sound according to the operation. The output of the speaker 54 will be described later. The play button 56 is a button for re-notifying the content that was most recently voice-reported.

  The microphone 58 is for inputting ambient sounds and adjusting the output volume of the speaker 54 in accordance with the ambient volume. The microphone 58 may be used as a recording input unit for a doctor or the like to record medical guidance for each patient as voice. When measuring the ambient sound volume (unit: [dB] in this embodiment) corresponding to the ambient sound input from the microphone 58, it is within a set time (for example, 1 to 5 seconds) that can be varied by the control unit 60. What is necessary is just to perform averaging processing of ambient sound input, filtering processing for ambient sound input, and the like. The speaker 54 and the microphone 58 are not limited to the type built in the blood glucose meter 10a, and may be, for example, an attachable / detachable type or an external type.

  A small protrusion having a different pattern is provided on the surface of the time setting button 44, the power button 50, the memory call button 52, the reproduction button 56, and the automatic adjustment button 100 described later, and can be identified by the tactile sense of the fingertip.

  As shown in FIG. 4, the volume switch 40a is a switch that moves the slider 59 in five steps on the left and right, and can select automatic volume adjustment, sound output off, volume low, volume low, and volume high sequentially from the right. Right below the volume switch 40a on the side surface, "automatic", "off", "small", "medium", and "large" are displayed in order from the right corresponding to the triangular protrusion pointer of the slider 59. .

  For example, when the slider 59 is moved to a position indicated by a virtual line, “automatic”, that is, automatic volume adjustment is selected. The slider 59 is provided with a plurality of vertical protrusions and can be easily moved in the horizontal direction using a fingertip.

  The volume switch 40a also functions as a function switching unit that switches on / off of the function of automatic volume adjustment. The volume switch 40a is on when the internal “automatic” terminal 69a is selected, and the “off” terminal 69b, “small”. When the terminal 69c, the “medium” terminal 69d, or the “large” terminal 69e is selected, it is turned off. The “off” terminal 69b, the “small” terminal 69c, the “medium” terminal 69d, and the “large” terminal 69e serve as a volume manual adjustment unit for manually adjusting the volume of the audio output when the automatic volume adjustment function is not used. Works.

  The contents output by voice here are information related to blood glucose measurement and treatment, and include measured measurement result values, operation procedure guidance, error notification, countermeasures, treatment guidance, and the like.

  When the volume switch 40a is moved to the right end, the volume switch 40a becomes “automatic” and adjusts the volume of the audio output according to the environment, so that the output contents can be easily heard. The volume switch 40a is located at a position where it can be easily operated with the thumb while holding the blood glucose meter 10a with the right hand. When the thumb is bent to the proximal side, the slider 59 moves to the right end in FIG. Easy to set and easy to operate even for users with low vision.

  Furthermore, if the slider 59 is moved to the left end in FIG. 4, it becomes “large”, and if it is moved to either the left or right end, it becomes easier to hear the sound in either case, and the patient whose visual acuity is reduced. But you can operate with confidence.

  Hereinafter, when the “automatic” terminal 69a is selected by the slider 59, “automatic volume adjustment” is selected, and when the “off” terminal 69b is selected, “sound output off” and “small” terminal 69c are selected. "Low volume", "Medium" terminal 69d is selected as "Volume", and "High" terminal 69e is selected as "Volume high". In the case of “Automatic volume adjustment”, when the volume is set to the same volume as “Low volume” by the volume automatic adjustment function, “Automatically low” is set to the same volume as “Low volume”. "When the volume is set to the same volume as" High volume ", it is expressed as" Automatic high ".

  The output sound volume is set to approximately 62 dB for “high volume”, 56 dB for “medium volume”, and 45 dB for “low volume” at a distance of about 10 cm.

  As shown in FIG. 5, the whole blood glucose meter 10a is controlled by the control unit 60 in an integrated manner. The blood glucose meter 10a includes a power source 62, a clock 64, a storage unit 66, and a measurement unit 68 therein. For example, a button battery is used as the power source 62, and power is supplied to the control unit 60 under the action of the power button 50. The clock 64 is adjusted by operating the time setting button 44 and notifies the control unit 60 of the current time. The clock 64 may be provided with a calendar function. Detailed description regarding the time setting operation of the clock 64 is omitted.

  The measuring unit 68 is optical, and includes a light emitting unit 68a that irradiates the test paper 20 (see FIG. 3) with light in pulses, a light receiving unit 68b that receives the light reflected by the colored test paper 20, and the light receiving unit 68b. An A / D converter 68c that converts a light reception signal of the light receiving unit 68b into a digital value and supplies the digital value to the control unit 60; Note that the test paper 20 and the measurement unit 68 are not limited to the optical type, and may be an electrode type using amperometry, for example.

  In the volume switch 40a, any one of an “automatic” terminal 69a, a “off” terminal 69b, a “small” terminal 69c, a “medium” terminal 69d, or a “large” terminal 69e is selected according to the position of the slider 59, and is sent to the control unit 60. Entered.

  The display 36, the time setting button 44, the memory call button 52, the speaker 54, the playback button 56, the microphone 58, the power source 62, the clock 64, the storage unit 66, and the measurement unit 68 are connected to the control unit 60. As the control unit 60, for example, a microcomputer is used, and a predetermined program is read and software processing is executed in cooperation with each functional unit.

  As shown in FIG. 6, the storage unit 66 includes a program 70, a work memory 72, an audio data memory 74, and a set value memory 76. The program 70 is software that is read and executed by the control unit 60. The work memory 72 is used for storing predetermined data each time the program 70 is executed. The voice data memory 74 is an area for storing several announcements in the operation of the blood glucose meter 10a as voice data. For example, “Power is turned on”, “Battery is running low”, “Measurement is performed” . ”,“ Set time ”, etc. The set value memory 76 is a memory for storing and storing predetermined data of the blood glucose meter 10a when the power is turned off. For example, a set volume level by a volume automatic adjusting unit 90 described later and a plurality of past blood glucose measurement values are stored. Is done.

  In FIG. 6, in order to avoid complication, the storage unit 66 is shown as one, but the program 70 and the audio data memory 74 are ROM (Read Only Memory), and the work memory 72 is RAM (Random Access Memory). The set value memory 76 may be a writable nonvolatile memory (for example, a flash memory).

  As shown in FIG. 7, the control unit 60 includes a mode management unit 80, a calculation unit 82, a measurement value output unit 84, a voice output instruction unit 86, and a speaker control unit 88. In FIG. 7, functional units having a small relationship with the gist of the present invention are omitted.

  The mode management unit 80 performs overall mode management and timing management of the blood glucose meter 10a, and gives operation instructions to other functional units. Further, regarding the output of the speaker 54, the mode management unit 80 distinguishes “automatic volume adjustment mode” when the automatic volume adjustment function is on, and “volume manual adjustment mode” when it is off. To do. Further, regarding the timing of blood glucose measurement, a preparation mode until the mounting of the chip 12 is confirmed, a measurement mode from the mounting of the chip 12 until the blood glucose level is calculated, and a display mode for displaying the result are distinguished (see FIG. 8). .

  The calculation unit 82 calculates the blood glucose level based on the signal supplied from the measurement unit 68. The measurement value output unit 84 displays and outputs the blood glucose level obtained by the calculation unit 82 on the display 36 and gives an audio output instruction to the audio output instruction unit 86. The voice output instruction unit 86 converts the blood glucose measurement value and predetermined voice data supplied from the measurement value output unit 84 into voice output format data. The reading of the measurement result value and the voice data of the operation guide are selected from the voice data memory 74 of the storage unit 66 under the instruction of the mode management unit 80 and used in combination in some cases.

  The speaker control unit 88 includes a volume automatic adjustment unit 90, a volume setting unit 92, and an amplifier 94. The volume automatic adjustment unit 90 is turned on (that is, “volume automatic adjustment mode”) when “automatic volume adjustment” is selected when the “automatic” terminal 69a of the volume switch 40a is selected, and is input from the microphone 58. The ambient volume is determined, and the output volume of various information output from the speaker 54 is adjusted / set to, for example, one of three levels according to the ambient volume. That is, when the ambient volume input from the microphone 58 is 20 dB or less, “automatically low” (the same volume as “low volume”) is set, and when it exceeds 20 dB and is 70 dB or less, “automatically” (same as “medium volume”). When the volume exceeds 70 dB, “automatically large” (same volume as “large volume”) is set. The information on the set volume level is supplied to the amplifier 94 via the volume setting unit 92 and is subsequently reflected in the volume of the audio output information output from the speaker 54. A parameter indicating the set volume is stored in the set value memory 76.

  The sound volume automatic adjustment unit 90 maintains the sound volume set before the sound is output from the speaker 54 and in the measurement mode in which the predetermined component of the body fluid is measured by the measurement unit 68. As a result, it is possible to prevent unnatural changes in the volume of voice notification during a series of periods, that is, during voice output or blood glucose measurement.

  Further, when detecting the ambient volume from the microphone 58, the volume automatic adjustment unit 90 pauses the sound level detection process while the sound is output from the speaker 54. Thereby, the surrounding sound volume can be detected without being influenced by the sound generated by the blood glucose meter 10a itself.

  Furthermore, the volume automatic adjustment unit 90 adjusts the volume of the audio output to one of a plurality of fixed levels. The multi-level volume is the same as the “small volume”, “medium volume”, and “large volume” when the “small” terminal 69c, “medium” terminal 69d, and “large” terminal 69e are selected by the volume switch 40a. You may set so that it may become volume. This makes it easier for the user to recognize the change in volume and the current volume. The form of the automatic volume controller 90 shown in FIGS. 7, 13, and 16 is, of course, one form for explaining the present invention, and the range defined as the automatic volume controller 90 is not limited thereto. For example, the speaker control unit 88 may be regarded as a “volume automatic adjustment unit”.

  The volume setting unit 92 is a part for setting the volume of the speaker 54. Specifically, when the “automatic” terminal 69a of the volume switch 40a is “automatic volume adjustment”, the volume set by the volume setting unit 92 is set. When the “low” terminal 69c is selected, “low volume” is selected, when “medium” terminal 69d is selected “medium volume”, and when “high” terminal 69e is selected, “high volume” is selected. The amplifier 94 is adjusted as follows. Further, when the “OFF” terminal 69b is selected, the amplifier 94 is adjusted so that the volume is zero, or the output line is shut off. The amplifier 94 amplifies the audio format signal supplied from the audio output instruction unit 86 so as to reach the volume level specified by the volume setting unit 92 and drives the speaker 54.

  Next, the operation and action of the blood glucose meter 10a configured as described above will be described with reference to FIGS. Initially, the 1st example of operation of the blood glucose meter 10a is demonstrated based on FIG.

  In FIG. 8, the timing at which the user turns on the blood glucose meter 10a by pressing the power button 50 is defined as time T0. At this time, it is assumed that the volume switch 40a has selected “automatic” (“automatic volume adjustment”). That is, in FIG. 4, the slider 59 is at the virtual line position and the “automatic” terminal 69a is selected. 8 to 10, this state is referred to as “automatic adjustment button on” for convenience.

  The preparation mode is from time T0 to time T1 when the mounting of the chip 12 is confirmed.

  At time T0, the control unit 60 confirms the state of the volume switch 40a. When the control unit 60 recognizes that the “automatic” terminal 69a is selected, the automatic volume adjustment unit 90 starts the automatic volume adjustment process. That is, the ambient volume input from the microphone 58 is determined, and the volume of the speaker 54 is set according to the ambient volume. It is assumed that it takes until time T01 to determine the surrounding volume. Time T01 is before time T1.

  Note that, as described above, the volume automatic adjustment unit 90 temporarily stops the detection of the surrounding volume from the microphone 58 while the sound is output from the speaker 54. For example, when the amount of power stored in the power source 62 decreases to a predetermined threshold between time T0 and time T01 and a voice announcement “Battery is running low” is output, ambient volume detection from the microphone 58 is detected. Pause. If the information does not need to be output immediately, the output may be suspended until the detection of the surrounding volume from the microphone 58 is completed (time T01). Thereby, it is possible to detect the ambient sound volume without being affected by the sound generated by itself.

  At time T01, the volume automatic adjusting unit 90 sets the volume of the speaker 54 to one of three levels of “automatically low”, “automatically”, and “automatically high” based on the ambient volume input from the microphone. Thereafter, it is reflected in the voice announcement output from the speaker 54. A parameter indicating the set volume is stored in the set value memory 76.

  As described above, every time the blood glucose meter 10a is turned on by the power button 50, the volume automatic adjustment unit 90 determines the ambient volume input from the microphone 58 and adjusts the output volume of the voice announcement. Therefore, even if the usage environment is different every time, the sound volume is appropriate for the usage environment.

  At time T0, a voice announcement such as “Power is turned on” or “Please insert a chip” is output from the speaker 54. This output is generally before the time T01, and the volume by the volume automatic adjustment unit 90 is Adjustment is not finished. However, since the parameter indicating the volume when the volume was adjusted last time is stored in the set value memory 76, the volume setting unit 92 may set the volume temporarily based on this parameter.

  During the preparation mode, the user removes the cap 46 (see FIG. 1) and attaches the chip 12 to the chip mounting portion 28. Then, the measurement unit 68 detects that the chip 12 is mounted, ends the preparation mode under the management of the mode management unit 80, and enters the measurement mode. The measurement mode is from time T1 at this time to time T2 at which the measurement ends.

  At time T1, a voice announcement such as “A correct chip has been attached” or “Please puncture and apply blood to the chip” is output from the speaker 54. Since the sound volume is set appropriately, the user can hear clearly.

  The user drops blood on the spotting portion 22 (see FIG. 3) of the chip 12 according to the voice guidance. The blood spotted on the spotting section 22 is guided to the test paper 20 through the blood introduction path 24.

  The light emitting section 68a emits light in a predetermined pattern after the power is turned on, and the amount of reflected light from the test paper 20 changes when the test paper 20 is impregnated with blood. Further, glucose in the blood reacts with the coloring reagent to cause color development, and the amount of reflected light received by the light receiving portion 68b decreases. Time measurement is started from the time when the previous blood impregnation is detected, and the blood glucose level is calculated based on the light reception signal at the light receiving unit 68b after a predetermined time has elapsed (for example, after 9 seconds). At this time, a voice announcement “measuring” or an intermittent beep sound indicating that measurement is in progress may be output from the speaker 54. The volume by automatic volume adjustment is also reflected in intermittent beeps.

  The calculation unit 82 performs hematocrit correction and temperature correction when obtaining the blood glucose level based on the received light signal.

  The calculated measurement value is displayed on the display 36 via the measurement value output unit 84, and is output from the speaker 54 via the audio output instruction unit 86 and the amplifier 94. This ends the measurement mode (time T2).

  The measured value is not only displayed on the display 36, but is also output from the speaker 54 with an appropriate sound volume according to the use environment, so that even a user with low vision can accurately grasp it.

  Thereafter, the user operates the ejector 30 to remove the chip 12 and presses the power button 50 to turn off the blood glucose meter 10a when the measurement is finished. The chip mounting portion 28 is covered with a cap 46. As described above, since the parameter indicating the volume set by the volume automatic adjustment unit 90 is stored in the set value memory 76 even when the power is turned off, the volume based on the parameter is first reflected at the next operation. become.

  On the other hand, when the measurement is performed again, the measurement unit 68 optically detects that the chip 12 has been removed (time T3). Return. Even when returning to the preparation mode, the sound volume set at the time T01 is maintained by the sound volume automatic adjustment unit 90, and the sound announcement is output at an appropriate sound volume, so that the measurement can be continued again according to the sound announcement.

  FIG. 9 shows a second operation example of the blood glucose meter 10a. In this second operation example, at the time T0 when the power is turned on, the volume is “low volume”, “medium volume”, “high volume”, or “sound output off”, and the time in the measurement mode. This is a case where the automatic adjustment button is turned on at T11.

  In this case, since the time T11 is in the measurement mode, the automatic volume adjustment is not performed immediately, and the sound volume at that time (“volume low”, “medium volume”, “volume high” or “sound output off”) Is maintained. The automatic sound volume adjustment function is turned on from time T2 when the measurement mode ends and the “automatic sound volume adjustment mode” is set, the surrounding sound volume input from the microphone 58 is determined, the sound volume is determined at time T21, and the subsequent voice announcements It is reflected in.

  As described above, during the measurement mode in which the blood glucose level is being measured by the measurement unit 68, the sound volume is maintained, so that the voice announcement “measurement in progress” output in this series of periods is being performed. Therefore, it is possible to prevent a volume such as an intermittent beep sound indicating that the sound volume is unnaturally changed in the middle of the operation, and the user is not uncomfortable. Depending on the design conditions, the sound volume may be maintained during a series of periods in which sound is output from the speaker 54, not only in the measurement mode.

  FIG. 10 shows a third operation example of the blood glucose meter 10a. This third operation example is opposite to the second operation example in FIG. 9, and the slider 59 of the volume switch 40a (see FIG. 4) is changed from “automatic” to “small”, “at” at time T12 in the middle of the measurement mode. This is a case of changing to either “medium” or “large”. In FIG. 10, this state is represented as “automatic adjustment button off” for convenience.

  In the third operation example, after time T12, the automatic volume adjustment is turned off, and the volume of the speaker 54 is set corresponding to any one of “small”, “medium”, and “large” selected by the volume switch 40a. To do.

  In the third operation example, the volume automatic adjustment is initially performed, but the user feels that the sound heard is too low or too high, and the volume switch 40a is operated to change the volume. In such a special case, the user's request is given priority, and the volume may be changed based on the operation of the volume switch 40a even during the measurement mode.

  Next, a blood glucose meter 10b according to a second embodiment will be described with reference to FIGS. In the blood glucose meter 10b and a blood glucose meter 10c described later, the same parts as those in the blood glucose meter 10a according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 11 and 12, the blood glucose meter 10b according to the second embodiment is provided with a volume switch 40b (volume manual adjustment unit) instead of the volume switch 40a, and is independent of the volume switch 40b. The automatic adjustment button (function switching unit) 100 is provided.

  The volume switch 40b does not have an “automatic” terminal 69a corresponding to “automatic” in the volume switch 40a, and can select “off”, “small”, “medium”, and “large”. As shown in FIG. 13, the automatic adjustment button 100 is connected to the volume automatic adjustment unit 90 of the control unit 60 and is a button for instructing the volume automatic adjustment unit 90 to switch on / off the volume automatic adjustment. .

  In the blood glucose meter 10b, as is apparent from FIG. 12, the volume switch 40b can be selected and set independently of the operation of the automatic adjustment button 100 in terms of operation. In the blood glucose meter 10b, every time the automatic adjustment button 100 is pressed, the automatic volume adjustment function by the automatic volume adjustment unit 90 is switched on / off. In the “manual adjustment mode” which is off, the selection of the volume switch 40b has priority. The state is any one of “low volume”, “medium volume”, “high volume”, and “sound output off”.

  Whether the automatic volume adjustment function is on or off may be displayed, for example, on the display 36, or may be guided by voice every time switching is performed, or the automatic adjustment button 100 itself is turned on / off. May be displayed. Moreover, if the automatic adjustment button 100 is an alternate type changeover switch, it can be determined to which state it has been switched visually or tactilely.

  Next, the operation and action of the blood glucose meter 10b configured as described above will be described with reference to FIGS. Initially, the 1st example of operation of the blood glucose meter 10b is demonstrated based on FIG. The time display and mode in FIGS. 14 and 15 are the same as those in FIGS.

  In FIG. 14, at time T0 when the blood glucose meter 10b is turned on, the automatic volume adjustment function is turned off, and an audio announcement is initially output at the volume selected by the volume switch 40b.

  When the automatic adjustment button 100 is pressed at time T02 in the preparation mode, the automatic volume adjustment processing is started under the action of the automatic volume adjustment unit 90. That is, the ambient volume input from the microphone 58 is determined, and the volume of the speaker 54 is set according to the ambient volume. It is assumed that it takes until time T03 to determine the ambient volume.

  At time T03, the volume automatic adjustment unit 90 sets the volume of the speaker 54 to one of three levels (“automatically low”, “automatically”, and “automatically high”) based on the ambient volume input from the microphone. To do. The set volume is supplied to the amplifier 94 via the volume setting unit 92 and is subsequently reflected in the voice announcement output from the speaker 54. If the time T03 is after the time T1 (that is, the measurement mode), the volume before automatic adjustment may be maintained.

  The blood glucose meter 10b has no means for holding the power off when the power is turned off. When the power is turned off, the volume automatic adjustment is turned off and the power is turned on again (time T0). The setting takes precedence. Depending on the design conditions, when the power is turned on, the automatic volume adjustment may be set to the “automatic volume adjustment mode”. Further, whether the “volume automatic adjustment mode” or the “volume manual adjustment mode” is set when the power is turned on may follow the state when the power is turned off. In this case, at the time T0 when the power is turned on, it is preferable to output whether it is “volume automatic adjustment mode”, “volume manual adjustment mode” or sound output off by voice or a display screen.

  FIG. 15 shows a second operation example of the blood glucose meter 10b. In this second operation example, the volume is “low volume”, “medium volume”, “high volume” or “sound output off” between time T0 when the power is turned on and time T11 in the measurement mode. In this case, the automatic adjustment button is turned on at time T11 in the measurement mode.

  This case is the same as the example shown in FIG. 9, and since the time T11 is in the measurement mode, the automatic volume adjustment is not performed immediately, and the volume at that time (“volume low”, “medium volume”, “Volume up” or “sound output off”) is maintained. The automatic volume adjustment function is turned on from time T2 when the measurement mode ends, the surrounding volume input from the microphone 58 is determined, the volume is determined at time T21, and is reflected in the subsequent audio output.

  As described above, the blood glucose meter 10b includes an automatic adjustment button 100 for switching on / off the function of the volume automatic adjustment unit 90, and a volume switch for adjusting the output volume of the voice announcement when the volume automatic adjustment function is off. 40b, and can be manually set to a predetermined volume as needed or at the discretion of the user.

  Next, a blood glucose meter 10c according to a third embodiment will be described. The appearance of the blood glucose meter 10c is the same as that of the blood glucose meter 10b (see FIGS. 11 and 12).

  As shown in FIG. 16, the control unit 60 in the blood glucose meter 10 c includes an addition correction unit 102. The addition correction unit 102 adds the volume set by the volume automatic adjustment unit 90 to the basic volume selected by the volume switch 40 b and set by the volume setting unit 92, and supplies the corrected volume to the amplifier 94. As a result, the amplification factor of the amplifier 94 is set at the volume level obtained by the addition correction unit 102. When “OFF” is selected with the volume switch 40b, the sound output from the speaker 54 is stopped.

  The automatic volume control unit 90 of the blood glucose meter 10c is switched on / off each time the automatic adjustment button 100 is pressed, and outputs “0” as an addition amount to the addition correction unit 102 when the manual adjustment mode is off. .

  An example of the operation of the blood glucose meter 10c is similar to that of the above-described example of the operation of the blood glucose meter 10b, and is not shown.

  According to such a blood glucose meter 10c, with the basic volume set by the volume switch 40b as a reference, the volume is compensated by the volume automatic adjustment unit 90 and the addition correction unit 102 according to the ambient volume, and the output volume of the voice announcement is increased. adjust. Thereby, it can set to a suitable volume according to the hearing ability for every user. That is, there is a difference in hearing between individuals when used by a hearing-impaired user, but according to the blood glucose meter 10c, the volume can be appropriately changed in accordance with such individual differences in hearing and the surrounding sound volume. .

  As described above, according to the blood glucose meters 10a, 10b, and 10c according to the first to third embodiments, the microphone 58 is provided to determine the surrounding volume, and the volume of the voice announcement is automatically set according to the surrounding volume. As a result of the adjustment, the volume does not need to be operated each time, and an appropriate volume according to the surrounding volume is obtained. It may be a burden to adjust the volume for patients with low vision or blindness due to complications or aging, and even if there is no abnormality in visual acuity, the volume is adjusted appropriately according to the surrounding volume. Although it may be cumbersome to do, the blood glucose meters 10a, 10b, and 10c provide operability simply.
