Abstract

A component measurement device (10) provided with a volume-switching switch (40) for switching a sound volume, indicative of a measurement value for a predetermined component of a bodily fluid, outputted from a speaker (58). The volume-switching switch (40) switches the sound volume outputted from the speaker (58) between at least a quiet whisper volume and a normal volume. The whisper volume has a noise level within the range 36-53 dB as measured by a noise meter (70) when the distance between the component measurement device (10) and a microphone (72) of the noise meter (70) is 3 cm within an anechoic room, and the normal volume has a noise level of 50 dB or greater as measured by the noise meter (70) when the distance between the component measurement device (10) and the microphone (72) of the noise meter (70) is 50 cm within an anechoic room.

Description

Component measuring device and medical device

The present invention relates to a component measuring apparatus and a medical device that measure a predetermined component or vital sign in a body fluid and output the measured value from a speaker.

In the treatment of diabetes, daily management by measuring daily blood glucose levels is recommended, and patients themselves measure blood glucose levels using a blood glucose meter.

However, diabetics may have low vision or blindness due to complications, and even if they are not complications, vision may be diminished due to older age. It is difficult to read information such as measured values displayed on the screen.

JP-A-2003-58359, JP-A-2007-41920, and JP-A-4395146 are equipped with a function for notifying information by voice so that information such as measured values can be known without relying on vision. A blood glucose meter and a system using the blood glucose meter are described.

However, information such as measured values is personal information, and there are cases in which it is not desirable for a person other than the person (the surrounding person) to ask for the information in a crowded environment. When the information is output by voice, information related to surrounding people can be heard. In addition, when the ambient noise is large, information such as the measurement value output by voice is erased by the ambient noise, and the information such as the measurement value may not be heard. The same applies to medical devices that measure not only component measuring devices such as blood glucose meters but also other vital signs (body temperature, blood pressure, heart rate, blood flow, etc.).

The present invention has been made in view of the above-described conventional problems, and prevents the information from leaking to the people around it, and the volume by which the sound output information can be heard even when the surroundings are noisy An object of the present invention is to provide a component measuring apparatus and a medical device in which stages are set.

The component measuring apparatus according to the present invention has the following characteristics.

First feature: a measurement unit that measures a predetermined component of body fluid, a sound output control unit that outputs sound indicating a measurement value measured at least by the measurement unit from a speaker, and a volume that is output from the speaker A volume change switch, and a volume change unit that changes the volume of the sound that the sound output control unit outputs from the speaker by switching with the volume change switch, the volume change switch comprising: , A switch for switching the sound output from the speaker to at least a fine volume and a normal volume larger than the volume, and the sound output when the volume is selected by the volume selector switch. The volume of the sound output from the speaker by the control unit is the same as that of the component measuring device and the sound level meter in the anechoic chamber. When the distance between the microphone is 3 cm, the noise level measured by the noise meter is in the range of 36dB ~ 53 dB.

As a result, if the surrounding person does not want to know the measured value, the volume of the sound output from the speaker can be switched to the whispering volume by the volume switch. Is not heard, and the measured value does not leak to surrounding people. In addition, when switching to the whispering volume, the user can sufficiently listen to the measured value even when the surroundings are noisy by placing the component measuring device on the ear.

Second feature: When the normal volume is selected by the volume switch, the volume of the sound output from the speaker by the sound output control unit is determined in the anechoic sound chamber by the component measuring device and the noise. When the distance between the meter and the microphone is 50 cm, the noise level measured by the sound level meter is 50 dB or more.

As a result, when there is no person around, or when the measurement value may be known to the surrounding people, the sound volume output from the speaker is switched to the normal sound volume by the sound volume selector switch. Can be used.

Third feature: The normal volume includes a first volume and a second volume that is higher than the first volume, and the volume switch switches the sound output from the speaker to the first volume and the first volume. It is possible to switch between two volumes.

This allows the volume to be switched according to the ambient noise and the patient's hearing when listening to the sound with the component measuring device away from the ear.

Fourth feature: When the first volume is selected by the volume selector switch, the volume of the sound output from the speaker by the sound output control unit is determined in the anechoic chamber by the component measuring device and the When the sound level measured by the sound level meter is within a range of 55 dB ± 5 dB when the distance from the microphone of the sound level meter is 50 cm, and the second volume is selected by the volume switch, the sound level The volume of the sound output from the speaker by the output control unit is such that the noise level measured by the sound level meter is 60 dB when the distance between the component measuring device and the microphone of the sound level meter is 50 cm in an anechoic chamber. It is within the range of ± 5 dB.

Thereby, in the normal use in which the component measuring apparatus is used without approaching the ear, the measured value can be sufficiently heard even when the surroundings are noisy or the patient is far away.

Fifth feature; when the sound output control unit outputs a sound other than sound from the speaker, and the sound volume is selected by the volume switch, the sound other than sound output from the speaker When the distance between the component measuring device and the microphone of the sound level meter is 3 cm, the sound level measured by the sound level is within the range of 36 dB to 62 dB. This optimizes the volume of the sound other than the sound, such as a buzzer sound, and makes it easier to hear.

6th characteristic; The said speaker is provided in the inside of the housing | casing of the said component measuring apparatus, The sound from the said speaker is carried out outside in the said housing according to the sound from the said speaker. A vibration region to be transmitted is provided, and the vibration region and the volume changeover switch are provided at substantially the same position with respect to the longitudinal direction of the component measuring device on one surface and the other surface of the housing.

Thus, if the component measuring device is brought close to the ear while holding the component measuring device so that a finger can come into contact with the volume switching switch to switch the volume, it will naturally occur. Since the vibration region can be brought close to the ear, handling becomes easy.

Seventh feature: the sound output control unit includes an amplifier that amplifies audio data, and the volume changing unit changes an input level to the amplifier by switching with the volume changeover switch. Thereby, the volume of the sound output from the speaker can be changed by operating the volume switch.

A medical device according to the present invention includes a measurement unit that measures a vital sign of a human body, a sound output control unit that outputs sound indicating a measurement value measured at least by the measurement unit from a speaker, and a volume output from the speaker A volume change switch for switching between, and a volume change unit for changing the volume of sound output from the speaker by the sound output control unit according to the change by the volume change switch, the medical device, The volume switch is a switch for switching the sound output from the speaker to a small volume and a normal volume larger than the volume, and when the volume is selected by the volume switch, The volume of the sound output from the speaker by the sound output control unit is the same as that of the medical device and the sound level meter in the anechoic sound room. When the distance between the click is 3 cm, the noise level measured by the noise meter is characterized in that in the range of 36dB ~ 53 dB.

As a result, if the surrounding person does not want to know the measured value, the volume of the sound output from the speaker can be switched to the whispering volume by the volume switch. Is not heard, and the measured value does not leak to surrounding people. In addition, when switching to the whispering volume, the user can hear the measurement value sufficiently even when the surroundings are noisy by placing the medical device on the ear.

According to the present invention, if the surrounding person does not want to know the measured value, the volume of the sound output from the speaker can be switched to the volume by the volume switch, and the measured value is shown to the surrounding person. No sound can be heard and the measured values are not leaked to the surrounding people. In addition, when switching to the whispering volume, the user can sufficiently listen to the measured value even when the surroundings are noisy by placing the component measuring device or medical device on the ear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a component measuring apparatus and a medical device according to the present invention will be described in detail below with reference to the accompanying drawings.

1 is a perspective view of a blood glucose meter 10 which is an example of a component measuring apparatus and a medical device, FIG. 2 is a plan view of the blood glucose meter 10 shown in FIG. 1, and FIG. 3 is a proximal end side of the blood glucose meter 10 of FIG. It is the side view seen from.

The blood glucose meter 10 has a tip 12 as a test tool attached to the tip. The blood glucose meter 10 is mainly used as a personal use application in which the patient himself operates to measure blood glucose, but a medical worker or the like may be used for a patient in a medical facility. First, the chip 12 will be described. In the present embodiment, patients who use the blood glucose meter 10, medical staff, etc. may be collectively referred to as users.

FIG. 4 is a cross-sectional view of the chip 12. The tip 12 includes a bottomed cylindrical base tube 14, a flange 16 projecting radially from the bottom of the base tube 14, a weight-like nozzle 18 projecting from the bottom of the base tube 14, and a bottom of the base tube 14 And a test paper 20 installed on the 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. The blood introduction path 24 is set to have a sufficiently small diameter so that blood is sucked up by a capillary phenomenon, and introduces blood that has come into contact with the spotting portion 22 to the test paper 20.

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, N-ethyl N- (2-hydroxy-3-sulfopropyl), and the like. . The reagent may contain a predetermined buffer.

The chip 12 is a so-called disposable product, and is loosely fitted into the case 26 (see FIG. 1) as a single package. When blood glucose is measured, the film (not shown) attached to the base end side of the case 26 is peeled off, and the case 26 is put on the chip mounting portion 28 (see FIG. 1), so that the difference in fitting force is reached. Thus, the chip 12 can be mounted on the chip mounting portion 28 automatically and without touching by hand. After blood glucose measurement, by pushing the ejector 30 to the tip side, the internal lever engages and pushes the tip 12, and the tip 12 can be removed.

1 to 3, the blood glucose meter 10 includes a chip mounting portion 28 to which the chip 12 is mounted, an ejector 30 provided in the vicinity of the chip mounting portion 28 and on the upper surface of the housing 10 a of the blood glucose meter 10, The liquid crystal display 36 provided in the approximate center of the top surface of the housing 10a, the operation unit 38 provided on the base end side of the top surface of the housing 10a, and a plurality of steps provided near the base end portion of the side surface of the housing 10a. A volume selector switch 40 that can switch the volume, a time setting button 44 provided at the base end (see FIG. 3) on the side surface of the housing 10a, and a cap 46 that is connected by a string and protects the chip mounting portion 28. Have The blood glucose meter 10 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 so that blood can be spotted easily.

The upper surface of the blood glucose meter 10 is formed in a flat shape, and the visibility of the display 36 and the operability of the operation unit 38 are good. The display 36 displays information such as the measured blood glucose level and predetermined input operation confirmation.

The operation unit 38 includes a power button 50 for turning on / off the control unit 80 (see FIG. 7) to which power is supplied from the power source 82, a memory call button 52 for reading a measurement value stored in the past, and the latest voice notification. And a reproduction button 54 for informing the contents again. Small protrusions with different patterns may be provided on the surface of the time setting button 44, the power button 50, the memory call button 52, and the play button 54, and these buttons can be identified by the touch of the fingertip.

A vibration region 56 is provided on the upper surface of the housing 10a, and a speaker 58 (see FIG. 7) is built in the back of the vibration region 56 (inside the housing 10a). The vibration area 56 vibrates in accordance with the sound output from the speaker 58, so that the sound output from the speaker 58 can be efficiently transmitted to the outside of the blood glucose meter 10. The vibration area 56 is provided between the power button 50 and the memory call button 52 and the play button 54.

As shown in FIG. 5, the volume switching switch 40 is a switch that can switch the volume of the sound output from the speaker 58 in four stages, the tip side of the blood glucose meter 10 is the wrist side, and the blood glucose meter 10 It is provided at a position where it can be easily operated with the thumb when it is held with the right hand so as to cover the back surface (the surface opposite to the surface on which the display 36 is provided). The volume changeover switch 40 is a switch that can move (slide) in four steps in a straight line direction, and can select “ringing volume”, “mute”, “small volume”, and “large volume” in order from the left. . In order to facilitate the movement of the volume changeover switch 40 by a finger operation, the volume changeover switch 40 is provided with a plurality of vertical protrusions that engage with the finger.

The volume changeover switch 40 is provided with a triangular protrusion pointer 40a. Below the triangular protrusion pointer 40a,

protrusions

60, 62, 64, 66 are formed corresponding to the position of the triangular protrusion pointer 40a of the volume changeover switch 40 in each stage. The protrusion 60 indicates the “sound volume” position, the protrusion 62 indicates the “mute” position, the protrusion 64 indicates the “volume low” position, and the protrusion 66 indicates the “volume high” position. Further, below the triangular protrusion pointer 40a and below the

protrusions

60, 62, 64, 66, in order from the left, a “heart” mark corresponding to “sound volume” and “mute” corresponding to “mute”. “Wedge” and “trapezoid” marks corresponding to the numbers “0”, “low volume”, and “high volume” are respectively displayed.

When the volume changeover switch 40 is slid to the position (first stage) where the triangular protrusion pointer 40a coincides with the protrusion 60 in the sliding direction, the volume of the sound output from the speaker 58 becomes a loud volume. When the volume changeover switch 40 is slid to a position (second stage) where the triangular protrusion pointer 40a coincides with the protrusion 62 in the sliding direction, the sound volume output from the speaker 58 becomes zero (0). No sound is output. The whispering volume is a volume that is so small that the sound from the speaker 58 cannot be heard unless the ear is brought close to the blood glucose meter 10 (if the distance between the blood glucose meter 10 and the ear is at least 15 cm).

When the volume selector switch 40 is slid to a position (third stage) where the triangular protrusion pointer 40a coincides with the protrusion 64 in the sliding direction, the volume of the sound output from the speaker 58 is low (normal volume, first volume). When the volume switch 40 is slid to a position (fourth stage) where the triangular protrusion pointer 40a matches the protrusion 66 in the sliding direction, the volume of the sound output from the speaker 58 is increased (normal volume, 2nd volume). The normal volume (low volume and high volume) means that the earphone is not brought close to the blood glucose meter 10 (for example, even when the distance between the blood glucose meter 10 and the ear is at least 15 cm or more). The volume is such that the sound can be heard, and the volume level is higher than the volume level. The details of the volume level, the low volume level, and the high volume level will be described later.

As described above, the user of the blood glucose meter 10 moves the volume switch 40 to the leftmost first stage (the front end side of the blood glucose meter 10), thereby increasing the volume output from the speaker 58. It can be switched (selected), and switching to a whispering volume becomes easy. On the other hand, if the position of the loud volume is set to the second position (second stage) or the third position (third stage) from the left without being set to the end, that is, when the middle position is set, A delicate operation is required to set the volume changeover switch 40 to the position, and it is difficult for a diabetic patient who tends to be inconvenienced to switch to the whispering volume.

Also, since the muffling position (second stage) is set to the right of the whispering volume, it is more difficult to switch to the muting by operating the volume selector switch 40 than to switch to the whispering volume located at the end. However, when the volume changeover switch 40 is slid from the low volume or high volume position to switch to mute, even if the volume changeover switch 40 cannot be stopped at the mute position and goes too far to the volume level, Since the sound volume cannot be heard unless the ear is brought close to the blood glucose meter 10, it can be used as a substitute for mute without causing any problem. Therefore, the user-friendliness can be improved by the volume switching arrangement as described above.

In addition, the user moves the volume switch 40 to the rightmost fourth stage (the proximal end side of the blood glucose meter 10), so that the volume output from the speaker 58 is maximized (the volume is increased). Can be switched to the loudest volume. On the contrary, if the position of the loud volume is set to the second position from the right (the position of the protruding portion 62) or the third position (the position of the protruding portion 64) without setting the end, that is, the intermediate position, A delicate operation is required to set the volume changeover switch 40 to an intermediate position, and it is difficult for a diabetic patient who tends to be inconvenient to switch the volume up.

In addition, since the low volume position (third stage) is set between the mute position (second stage) and the high volume position (fourth stage), the volume switch 40 is operated to adjust the volume. Switching to a lower volume is more difficult than switching to a higher volume, but if switching to a lower volume is not possible, the volume can be switched to higher. Since it is better to hear the sound more reliably than you can not hear the sound, the higher priority volume level is located on the right and the lower priority volume level lower than the higher volume level is second from the right. . Further, the volume increases as it goes to the right with the mute position as a reference, so that the user can intuitively adjust the volume. In addition, with the mute position as a reference, the volume level is set to the left side, and the low volume level and the high volume level are set to the right side, so that the user can adjust the volume level and normal volume adjustment (low volume and high volume). Switching can be performed intuitively and easily.

Next, the loudness, loudness, and whispering volume will be described. The sound volume for setting the sound volume was measured in the anechoic sound chamber by placing the microphone 72 of the noise meter 70 on the side where the vibration region 56 of the blood glucose meter 10 is located, as shown in FIG. At this time, it is assumed that there is no obstacle between the vibration region 56 of the blood glucose meter 10 and the microphone 72. As the sound level meter 70, a sound level meter (model number TYPE 1015) manufactured by Sotec (formerly Electronic Instruments) was used. The weight switch of the sound level meter 70 is set to “A” (set to A characteristic), and the dynamic characteristic changeover switch is set to “S” (dynamic characteristic is set to Slow). This A characteristic is defined by the standard of the sound level meter 70 of IEC 61672 and JIS C1509.

When the volume is selected by the volume selector switch 40, the volume output from the speaker 58 is measured by the sound level meter 70 when the distance L between the vibration region 56 of the blood glucose meter 10 and the microphone 72 is 50 cm. The sound level is within the range of 60 dB ± 5 dB. Therefore, the high volume is a volume at which the sound from the speaker 58 can be sufficiently heard even if the user does not bring the ear close to the blood glucose meter 10, and can be sufficiently heard even by a patient who is far away.

The volume output from the speaker 58 when the low volume is selected by the volume switch 40 is measured by the sound level meter 70 when the distance L between the blood glucose meter 10 and the microphone 72 of the sound level meter 70 is 50 cm. The sound level at which the noise level is within the range of 55 dB ± 5 dB. Therefore, the low volume is a volume at which the sound from the speaker 58 can be sufficiently heard if the user has normal hearing ability even if the user does not bring his ear close to the blood glucose meter 10.

In addition, when the sound output from the speaker 58 is a voice when the volume selection switch 40 is selected, the volume is set such that the distance L between the blood glucose meter 10 and the microphone 72 of the noise meter 70 is 3 cm. Sometimes, the sound level measured by the sound level meter 70 is a volume that falls within the range of 36 dB to 53 dB. If the sound output from the speaker 58 is a sound (sound effect) other than a sound such as a buzzer sound when a whispering volume is selected by the volume selector switch 40, the sound volume is set to the blood glucose meter 10 and the sound level meter 70. When the distance L from the microphone 72 is 3 cm, the sound level measured by the sound level meter 70 is a volume that falls within the range of 36 dB to 62 dB. Even with the same volume level, the sound level differs slightly between sound and non-voice sound.

The whispering volume is a volume at which the sound from the speaker 58 cannot be heard unless the user puts his ear close to the blood glucose meter 10, and by touching the blood glucose meter 10 (by touching the vibration region 56 of the blood glucose meter 10). In this case, the sound volume is sufficient for the sound from the speaker 58 to be heard. Even when the surroundings are noisy (when surrounding noise is troublesome), the blood glucose meter 10 is in a state of closing the ear, so that the patient can sufficiently hear the sound from the speaker 58.

Note that the loudness level, the low volume level, and the loudness level measured by the sound level meter 70 described above are noise levels measured in an anechoic chamber, that is, in an environment where there is no extra noise around. The noise level of the sound level meter 70 during silence was 34 dB.

Here, the position where the vibration region 56 and the volume changeover switch 40 are provided is provided at substantially the same position with respect to the longitudinal direction of the blood glucose meter 10 on the upper surface and the side surface of the housing 10a. That is, after gripping the blood glucose meter 10 with the right hand so that the thumb hits the volume changeover switch 40, when the vibration area 56 is applied to the right ear, the vibration area 56 and the volume changeover switch are set so that the thumb of the right hand comes to the ear. 40 is provided. As a result, if the blood glucose meter 10 is brought to the right ear so that the thumb comes to the ear, the vibration region 56 naturally hits the right ear, so that the vibration region 56 can be easily applied to the right ear.

FIG. 7 is a block diagram showing an electrical configuration of the blood glucose meter 10. The blood glucose meter 10 controls the entire blood glucose meter 10 in an integrated manner, in addition to the display 36, the volume changeover switch 40, the time setting button 44, the power button 50, the memory call button 52, the playback button 54, and the speaker 58. A control unit 80, a power source 82, a clock 84, a storage unit 86, and a measurement unit 88 are provided.

For example, an alkaline battery is used as the power source 82, and power is supplied to the control unit 80 under the action of the power button 50. The clock 84 is adjusted by operating the time setting button 44 and notifies the control unit 80 of the current time. The clock 84 may be provided with a calendar function.

As shown in FIG. 8, the storage unit 86 includes a program memory 86a, a work memory 86b, an audio data memory 86c, and a set value memory 86d. The program memory 86a stores a program for the control unit 80 to read and execute. The work memory 86b is used for storing predetermined data when the program is executed. The voice data memory 86c stores voice data of voices to be announced when the blood glucose meter 10 is operated. For example, “Power is turned on”, “Replace the battery”, “Measurement”. Voice data such as “In the middle” and “Set the time” are stored. The sound data memory 86c also stores sound data of sound other than sound, for example, sound effects such as buzzer sound and warning sound. The set value memory 86d is a memory for storing and storing predetermined data when the power supply 82 is turned off. For example, blood glucose levels measured in the past are stored.

The measuring unit 88 is optical, and includes a light emitting unit 88a that irradiates the test paper 20 (see FIG. 4) with pulsed light, a light receiving unit 88b that receives the light reflected by the colored test paper 20, An A / D converter 88c that converts a light reception signal of the light receiving unit 88b into a digital value and outputs the digital value to the control unit 80; In the present embodiment, the blood glucose level is obtained by an optical method, but the blood glucose level may be obtained by an electrode method using amperometry or the like.

The control unit 80 includes a measurement control unit 90, a blood sugar level calculation unit 92, a display control unit 94, a sound output control unit 96, and a volume change unit 98, as shown in FIG. The measurement control unit 90 controls the measurement unit 88, and performs light emission control of the light emitting unit 88a, light reception control of the light receiving unit 88b, and the like. The blood glucose level calculation unit 92 calculates the blood glucose level based on the light reception signal supplied from the measurement unit 88 (specifically, the A / D converter 88c).

The display control unit 94 controls the display 36 to display a 3-digit number indicating the blood glucose level calculated by the blood glucose level calculation unit 92 on the display 36. For example, when the calculated blood glucose level is 123 mg / dL, as shown in FIG. 2, three digits of “1”, “2”, “3” in order from the left (in order from the front end side of the blood glucose meter 10) A number is displayed on the display 36. In addition to the blood glucose level calculated by the blood glucose level calculation unit 92, the display 36 displays, for example, a sentence such as “Please replace the battery” and “Now measuring”, an icon indicating the content of the sentence, and the like. Display may be possible.

The sound output control unit 96 uses the audio data stored in the audio data memory 86c of the storage unit 86 to reproduce the audio data indicating the blood glucose level calculated by the blood glucose level calculation unit 92, and the blood glucose level from the speaker 58. Outputs a voice indicating. For example, when the calculated blood glucose level is 123 mg / dL, the voice data of “Kettuchiha”, “Hyaku”, “Niju”, “San”, “Da” is reproduced in the order described above. As a result, the sound of “blood glucose level is 123” is output from the speaker 58. The sound output control unit 96 includes an amplifier 96a, and audio data is amplified by the amplifier 96a. The sound output control unit 96 reproduces sound data (for example, sound effect sound data) other than the sound data, and alerts the speaker 58 at the start of measurement, at the end of measurement, or when an error occurs. May be output. Of course, even in this case, the sound data is amplified and reproduced by the amplifier 96a.

The volume changing unit 98 changes the input level to the amplifier 96a of the sound output control unit 96 according to the operation of the volume changeover switch 40. The volume changing unit 98 sets the input level to the amplifier 96a so that the volume of the sound output from the speaker 58 becomes the volume when the “ring volume” is selected by the volume switch 40. The volume changing unit 98 sets the input level to the amplifier 96a so that the volume of the sound output from the speaker 58 is reduced when “Low volume” is selected by the volume switch 40. The volume changing unit 98 sets the input level to the amplifier 96a so that the volume of the sound output from the speaker 58 becomes high when “high volume” is selected by the volume changeover switch 40. When “mute” is selected by the volume switch 40, the input level to the amplifier 96a may be set so that the volume output from the speaker 58 becomes 0, or the sound output control unit 96 The audio data may not be reproduced.

Next, the operation of the blood glucose meter 10 configured as described above will be described with reference to the flowchart of FIG. When the user presses the power button 50, the control unit 80 is activated. Then, the sound output control unit 96 outputs the sound “Power has been turned on” from the speaker 58 at the volume selected by the volume switch 40 (step S1). For example, when “Sound volume” is selected, the sound is output at a volume level, when “Low volume” is selected, the sound is output at a low volume, and “High volume” is selected. Outputs sound at high volume. If “mute” is selected, no sound is output from the speaker 58. At this time, the display control unit 94 may display a sentence “Power is turned on” or an icon indicating that the power is turned on on the display 36. Further, the sound output control unit 96 may output a sound effect for calling attention at a volume selected by the volume switch 40.

Next, the sound output control unit 96 outputs a voice “Please insert a chip” from the speaker 58 at the volume selected by the volume selector switch 40 (step S2). Based on the voice announcement, the user removes the cap 46, peels off the film attached to the base end side of the case 26, and attaches the chip 12 to the chip attachment portion 28. At this time, the display control unit 94 may display on the display 36 a sentence “please insert a chip” and an icon that prompts the user to mount the chip 12. Further, the sound output control unit 96 may output the sound effect at the volume selected by the volume switch 40.

Next, the blood sugar level calculating unit 92 determines whether or not the chip 12 is attached. This determination is made based on the amount of light received by the light receiving unit 88b (step S3). That is, in step S3, the blood sugar level calculating unit 92 determines the mounting of the chip 12 based on the light reception signal sent from the light receiving unit 88b via the A / D converter 88c. When the chip 12 is mounted, the light emitted from the light emitting unit 88a is reflected by the test paper 20 and enters the light receiving unit 88b, so that the amount of light received by the light receiving unit 88b increases. Therefore, when the light quantity received by the light receiving unit 88b is equal to or larger than the threshold value, it is determined that the chip 12 is attached.

If it is determined in step S3 that the chip 12 is not mounted, it remains in step S3 until it is mounted. At this time, when the chip 12 is not mounted for a certain time or longer, the sound output control unit 96 may output a warning sound from the speaker 58, or the display control unit 94 may perform warning display. . When this warning sound is output, it may be output at the volume selected by the volume switch 40, or may be output at a predetermined volume regardless of the volume selected by the volume switch 40. .

If it is determined in step S3 that the chip 12 has been mounted, the sound output control unit 96 outputs a sound “The chip has been mounted. Is output at the volume selected by (step S4). Based on this voice announcement, the user drops blood on the spotting portion 22 (see FIG. 4) of the chip 12. At this time, the display control unit 94 may display on the display 36 a sentence “Please drop blood on the chip.” Or an icon that prompts the user to drop blood. Further, the sound output control unit 96 may output the sound effect at the volume selected by the volume switch 40.

When the blood is spotted on the chip 12, coloration is started by the reaction between glucose in the blood and the reagent impregnated in the test paper 20. The measurement control unit 90 controls the measurement unit 88 so that the reflected light from the test paper 20 is received by the light receiving unit 88b to obtain a light reception signal, and the obtained light reception signal is digitalized by the A / D converter 88c. Let it be converted to a value.

Next, the blood sugar level calculating unit 92 calculates a blood sugar level based on the received light signal sent from the measuring unit 88 after a predetermined time has elapsed since it was determined that the chip 12 was attached (step S5). The sound output control unit 96 outputs the sound “measuring” from the speaker 58 at the volume selected by the volume selector switch 40 during the blood glucose level measurement (until the blood glucose level is calculated). May be. At this time, the display controller 94 displays the remaining time (seconds) until the end of measurement in a countdown manner. Note that a sentence “measuring” or an icon indicating that measurement is in progress may be displayed on the display 36.

Next, the sound output control unit 96 outputs the voice indicating the blood sugar level calculated by the blood sugar level calculating unit 92 at the volume selected by the volume switching switch 40 (step S6). For example, when the obtained blood glucose level is 157 mg / dL, the sound output control unit 96 outputs a sound “blood glucose level is 157” from the speaker 58. At this time, the display control unit 94 displays the number “157” on the display 36. Further, the sound output control unit 96 may output the sound effect at the volume selected by the volume switch 40.

As described above, the blood glucose meter 10 includes a measurement unit 88 that measures the blood glucose level, a sound output control unit 96 that outputs sound indicating the measurement value calculated based on the light reception signal from the measurement unit 88 from the speaker 58, and A volume switching switch 40 for switching the volume output from the speaker 58, and a volume changing section 98 for changing the volume of the sound output from the speaker 58 by the sound output control section 96 by switching with the volume switching switch 40; The volume switching switch 40 is a switch for switching the volume of the sound output from the speaker 58 to a loud volume, a small volume, and a large volume. The loud volume is a case where there is no extra noise around the blood glucose meter 10. When the distance between the user and the user's ear is at least 15 cm or more, the sound cannot be heard from the speaker 58. Even if there is no extra noise and the distance between the blood glucose meter 10 and the user's ear is 15 cm or more, the volume is such that the sound from the speaker 58 can be heard. If the user does not want to know the sound, the sound volume output from the speaker 58 can be switched to the sound volume by the volume switch 40.

In addition, when the volume is switched to the whispering volume, the patient or the like can sufficiently hear the measured value even when the surroundings are noisy by putting the ear on the blood glucose meter 10. Further, when there is no person in the surroundings or when the measurement value may be known to the surrounding people, the volume of the sound output from the speaker 58 is switched to a low volume or a high volume by the volume switch 40. Thus, the measured value can be sufficiently heard without performing the operation of putting the ear on the blood glucose meter 10.

Further, by switching the volume of the sound output from the speaker 58 by the volume switch 40 from the low volume to the high volume, the blood glucose meter 10 is applied to the ear even when the surroundings are noisy or the patient is far away. The measured value can be heard sufficiently without any operation.

The above embodiment may be modified as follows.

(Modification 1) In the above embodiment, the blood glucose meter 10 that measures blood sugar in body fluid has been described. However, any device that measures a predetermined component in body fluid other than blood sugar may be used. In this case, the measurement unit 88 has a function of measuring a predetermined component in body fluid other than blood sugar. Moreover, it is applicable also to the medical device which measures vital signs other than a body fluid component. In this case, the measuring unit 88 has a function of measuring vital signs.

In addition, the component measuring device and the medical device here are not limited to so-called personal use products, but of course include, for example, devices or devices handled by medical personnel for patients.

(Modification 2) In the above embodiment, as the slide position of the volume changeover switch 40, the position of the loud volume (first stage) is the leftmost, the mute position (second stage) is the second from the left, The position where the volume is high (fourth stage) is the rightmost position, and the position where the volume is low (third stage) is the second position from the right. The position where the volume is high may be the leftmost position, and the position where the volume is low may be the second position from the left. That is, one end of the slidable range of the volume changeover switch 40 may be set as the volume level, and the mute position may be adjacent to the volume level.

(Modification 3) In the above-described embodiment, the normal volume can be adjusted in two stages of low volume and high volume, but the normal volume may be adjusted in three or more stages. May not be adjusted. Even when the normal sound volume can be adjusted in three or more stages, the sound volume decreases as it is closer to the mute position, and the sound volume increases as it is farther from the mute position. Of course, the position of the normal sound volume is provided on the opposite side of the position of the loud sound volume with reference to the mute position. When the volume cannot be adjusted, the normal volume is a predetermined volume.

(Modification 4) The modification 1 to 3 may be arbitrarily combined.
