Description

The present invention relates to a blood glucose level measurement equipment used to measure the blood glucose level.

  Conventionally, a portable blood glucose level measuring device has been used to perform diagnosis, treatment, and medical guidance for diabetic patients. This blood glucose level measuring device is a device for measuring the glucose concentration in blood by a diabetic patient (user) himself / herself under the guidance of a doctor or a diabetes medical instructor.

  By the way, a diabetic patient may have a visual impairment due to the characteristics of the disease. Therefore, it is difficult for a diabetic patient to check characters or the like displayed on the display unit of the blood sugar level measuring device, and there is a possibility that the blood sugar level measuring device cannot be operated accurately.

  Therefore, a blood glucose level measuring device (Patent Document 1) for notifying an event such as an operation for measuring a blood glucose level, a measurement result, and an error that has occurred in order to make it usable even for a user with impaired vision is conceivable. It was. When detecting an event to be notified by voice (hereinafter referred to as “voice notification event”), the blood glucose level measuring apparatus reproduces an audio file corresponding to the detected voice notification event. Thereby, the sound according to the reproduced sound file is output from the sound output unit.

JP 2003-58359 A

  However, in the blood sugar level measuring apparatus described in Patent Document 1, when a plurality of sound notification events occur simultaneously or substantially simultaneously, all sound files corresponding to the sound notification events that have occurred are sequentially reproduced. For this reason, there has been a problem that a user who is unfamiliar with the operation of the apparatus or a user with impaired visual acuity is confused as to which voice notification should be dealt with from among a plurality of reproduced audio files.

  The present invention has been made in view of such a situation, and provides a blood glucose level measuring apparatus, a voice notification method, and a program capable of clearly showing a user voice notification that needs to be handled with the highest priority. Objective.

In order to solve the above-mentioned problems and achieve the object of the present invention, the present invention shows the priority of a voice notification event, the designated address of a voice file corresponding to the voice notification event, and whether or not a voice notification event has occurred. With reference to the data storage unit associated with the flag and stored, the number of sound notification events that are occurring is calculated, and each piece of information related to the sound notification event that is occurring is acquired. Then, when the calculated number of generated voice notification events is plural, the priorities of the generated voice notification events are compared. Then, the audio file corresponding to the audio notification event determined to have the highest priority is reproduced. Furthermore, when the playback button is operated, the audio file played back by the playback control unit is played back again. Then, when a new voice notification event occurs and the priority determination unit determines that the priority of the newly generated voice notification event is the highest, the playback control unit stops playback of the currently played audio file. The audio file corresponding to the newly generated audio notification event is reproduced.

According to the present invention, when a plurality of audio notification events are generated, only the audio file corresponding to the audio notification event having the highest priority among the audio notification events that are occurring can be reproduced. Then, when a new voice notification event occurs and the priority determination unit determines that the priority of the newly generated voice notification event is the highest, the playback control unit stops playback of the currently played audio file. The audio file corresponding to the newly generated audio notification event is reproduced. Thereby, there exists an effect that the audio | voice alert | report which needs to cope with top priority can be shown clearly to a user. In addition, by operating the playback button, it is possible to reproduce again the voice that the user missed, so that the user can be surely notified of the content of the reproduced voice.

The blood glucose level measuring apparatus 101 includes a light emitting unit 303 that emits light of a predetermined wavelength to the test paper 202, and a light receiving unit 304 that receives the light and generates a light reception signal.
The chip 110 includes a capillary tube 302 that sucks blood adhering to the tip by capillary action, and a test paper 202 into which the blood sucked through the capillary tube 302 soaks.

  For the light emitting unit 303, for example, a light emitting diode that emits light having a wavelength of 630 nm is used. For the light receiving unit 304, for example, a photodiode or a phototransistor is used.

  In a state where the chip 110 is attached to the holder 107, the light receiving unit 304 receives the light reflected from the test paper 202 and generates a light reception signal.

  The thin tube 302 of the chip 110 is made of a rigid material having a predetermined rigidity. Examples of such a rigid material include various resin materials. In particular, as a material suitable for rapid introduction and development of a specimen, a highly hydrophilic material such as an acrylic resin or a material subjected to a hydrophilic treatment is preferable.

  The test paper 202 is obtained by carrying (impregnating) a reagent (coloring reagent) on a carrier capable of absorbing blood (specimen). This carrier is preferably composed of a porous membrane (sheet-like porous substrate). In this case, the porous membrane preferably has a pore size that can filter out red blood cells in blood.

Examples of the carrier of the test paper 202 include, in addition to the porous film, a sheet-like porous substrate such as a nonwoven fabric, a woven fabric, and a stretched sheet.
Examples of the constituent material of the carrier such as the porous membrane include polyesters, polyamides, polyolefins, polysulfones, and celluloses, but it is impregnated with an aqueous solution in which a reagent is dissolved. In order to perform rapid development, a hydrophilic material or a material that has been subjected to a hydrophilic treatment is preferable.

  Examples of the reagent (coloring reagent) impregnated in the carrier (porous membrane) include glucose oxidase (GOD), peroxidase (POD), 4-aminoantipyrine (4-AA), N-ethyl-N- (2 And a color former such as -hydroxy-3-sulfopropyl) -m-toluidine (TOOS). Furthermore, a buffering agent such as a phosphate buffer may be included. Needless to say, the types and components of the reagents are not limited to these.

1-2. Internal Configuration Example of Blood Glucose Level Measuring Device Next, an internal configuration example of the blood glucose level measuring device 101 will be described with reference to FIG.

FIG. 5 is a block diagram showing an internal configuration of the blood sugar level measuring apparatus 101 according to the embodiment of the present invention.
In addition to the display unit 102, the audio output unit 112, the light emitting unit 303, and the light receiving unit 304, the blood glucose level measuring apparatus 101 includes an A / D conversion unit 409 that converts a light reception signal generated by the light receiving unit 304 into digital data, and each unit. A control unit 402, a control oscillation unit 403, a clock oscillation unit 404, a data storage unit 405, an external output unit 406, a power supply 407, a power supply voltage detection unit 408, and an operation unit 410.

  A printed circuit board provided in the housing 105 is equipped with a control unit 402 configured by a microcomputer (MPU: MicroProcessing Unit), and controls various operations of the blood glucose level measuring apparatus 101. The control unit 402 includes a calculation unit (not shown) that calculates a target blood component (glucose) based on a signal from the light receiving unit 304. This computing unit also performs, for example, hematocrit value correction calculation as necessary.

  The light emitting unit 303 and the light receiving unit 304 are housed and held in a holder 107 (see FIG. 3). The light emitting unit 303 is electrically connected to the control unit 402, and the light receiving unit 304 is electrically connected to the control unit 402 via an amplifier (not shown) and an A / D conversion unit 409.

  The light emitting unit 303 operates in response to a signal from the control unit 402, and emits pulsed light at a predetermined time interval. For example, the period of the pulsed light is about 0.5 to 3.0 msec, and the emission time of one pulse is about 0.05 to 0.3 msec. The wavelength of the pulsed light is preferably about 500 to 720 nm, more preferably about 580 to 650 nm.

  The tip 110 is detachably attached to the tip of the holder 107. When the chip 110 is mounted on the holder 107, the front end surface of the holder 107 faces the test paper 202 provided in the chip 110. In this state, the light emitted from the light emitting unit 303 is applied to the test paper 202, and the reflected light reflected by the test paper 202 is received by the light receiving unit 304 and subjected to photoelectric conversion. The light receiving unit 304 outputs an analog signal corresponding to the amount of received light and amplifies it to a desired value. Thereafter, the analog signal is converted into a digital signal by the A / D conversion unit 409 and input to the control unit 402.

  The control unit 402 measures the amount of received light based on the light reception signal supplied from the light receiving unit 304 via the A / D conversion unit 409. And the control part 402 measures the blood glucose level of the blood adhering to the test paper 202 based on the measured received light quantity. The measured blood glucose level is stored in a third memory (described later) of the data storage unit 405 in association with the measurement date and time of the blood glucose level.

  In addition, the control unit 402 detects whether or not a voice notification event has occurred. And the flag regarding the audio | voice alerting | reporting event which has generate | occur | produced is raised, and the flag regarding an audio | voice alerting | reporting event will be lowered, if an audio | voice alerting | reporting event is eliminated. This flag is written in the event information basic table 502 described later with reference to FIG.

  In addition, the control unit 402 confirms whether or not a flag relating to the voice notification event is set, and reproduces an audio file corresponding to the voice notification event in which the flag is set. Audio corresponding to the reproduced audio file is output from the audio output unit 112. However, when a plurality of audio notification events have occurred, only the audio file corresponding to the audio notification event having the highest priority is reproduced. Note that the function of the control unit 402 relating to audio reproduction control will be described later with reference to FIG.

  The control oscillating unit 403 constitutes a timer, oscillates clock pulses at regular time intervals, and supplies a reference signal for operation of the microcomputer of the control unit 402.

  The clock oscillation unit 404 constitutes a clock that specifies absolute time (date and time), oscillates clock pulses at regular time intervals, and supplies a reference signal for operation of the clock control circuit built in the control unit 402.

  The external output unit 406 outputs the obtained blood glucose level data to an external device such as a personal computer. For this reason, the external output unit 406 incorporates a communication port such as RS-232C, for example. When performing infrared communication, the external output unit 406 incorporates an infrared light emitting element and its drive circuit.

  As the power source 407, a battery (not shown) is loaded in the housing 105. The power source 407 supplies power to each block included in the blood sugar level measuring apparatus 101. The power supply voltage detection unit 408 detects the voltage of the battery and outputs the detected voltage value (detection value) to the control unit 402. Thereby, the remaining amount of the battery can be checked.

  The operation unit 410 is a general term for the power button 103, the history call button 104, and the like described above. The operation unit 410 detects input of various switches as described below, and inputs the signals to the control unit 402. Examples of the switch include a power switch, a history call switch, a time setting / change switch, a reset switch, a buzzer operation / non-operation selection switch, and a 50 Hz / 60 Hz commercial power frequency selection switch. The power switch switches on or off the power from the power source 407 when the power button 103 is pressed.

  The data storage unit 405 includes a first memory (RAM) (not shown), a second memory (ROM), and a third memory (nonvolatile RAM) that is a rewritable nonvolatile memory.

  In the first memory, digital data of the amount of received light input from the light receiving unit 304 is stored according to a predetermined format.

  In the second memory, a program for controlling the blood sugar level measuring apparatus 1 is stored. The second memory stores an audio file that is played back when an audio notification event occurs.

  In the third memory, a relationship (calibration curve) between the absorbance obtained from the photometric value and the target blood glucose level, and a calibration value unique to each individual blood glucose level measuring device 1 are stored in advance. Specific calibration values referred to here include, for example, a prescribed value of the amount of received light, a correction coefficient for absorbance calculation, and the like. In the third memory, blood glucose levels for several days measured in the past are stored in association with the measurement date and time.

The third memory stores an event information basic table 502 shown in FIG.
In the event information basic table 502, information for the control unit 402 to perform reproduction control of the audio file related to the audio notification event that is occurring is written.

  In the “event ID” field of the event information basic table 502, an ID for identifying a voice notification event is written.

  The “audio file storage destination address” in the event information basic table 502 includes an audio file to be reproduced when an audio notification event indicated by the event ID stored in the “event ID” field in the same record occurs. The address is written.

  In the “event flag” field of the event information basic table 502, a flag indicating whether or not an audio notification event indicated by the ID stored in the “event ID” field in the same record is written. That is, the voice notification event indicated by the ID stored in the “event ID” of the same record as the “event flag” in which “true” is stored corresponds to the voice notification event that is occurring. On the other hand, the voice notification event indicated by the ID stored in the “event ID” of the same record as the “event flag” in which “false” is stored is a voice notification event that is not occurring.

  In the “priority” field of the event information basic table 502, the priority of the voice notification event indicated by the ID stored in the “event ID” field in the same record is written. The priority stored in the “priority” field is, for example, three types of values “1”, “2”, or “3”, and the lower the value, the higher the priority.

  The audio notification event with the priority “1” corresponds to the audio notification event with the highest risk for the user, and is an audio notification event that occurs when the blood glucose level measurement result is abnormally high (or abnormally low).

  The audio notification event with the priority “2” corresponds to the audio notification event with the second highest risk for the user, and the surrounding temperature and brightness are not within the normal range or the chip 110 is contaminated. This is a voice notification event that occurs in

  The voice notification event of priority '3' corresponds to a voice notification event that is not very risky for the user, and is a voice notification event that occurs when the blood glucose level measurement result is normal or when the remaining battery level is insufficient. is there. It should be noted that audio notification events having the same priority are not generated at the same time.

1-3. Functional Configuration Example of Control Unit Next, a functional configuration of the control unit 402 related to audio file reproduction control will be described with reference to FIG.

FIG. 7 is a block diagram illustrating a functional configuration of the control unit 402 according to an embodiment of the present invention.
The control unit 402 includes a voice notification event detection unit 602, a priority determination unit 603, and a playback control unit 604.

  The voice notification event detection unit 602 checks the “event flag” field of the event information basic table 502 to calculate the number of voice notification events that are occurring. Specifically, the number of records in which the “event flag” field is “true” is calculated as the number of voice notification events that are occurring.

  Also, the voice notification event detection unit 602 acquires each piece of information (ID, priority, address, etc.) related to the voice notification event that is occurring from the event information basic table 502.

  Also, the voice notification event detection unit 602 constantly monitors the “event flag” field of the event information basic table 502, and confirms the new occurrence and cancellation of the voice notification event.

  The priority determination unit 603 responds to a newly generated voice notification event (its event ID) when the occurrence of a new voice notification event is detected and the number of generated voice notification events is detected to be plural. The priority to be compared is compared with the priority corresponding to the voice notification event that is occurring. Specifically, it is confirmed whether or not the priority of the newly generated voice notification event is the highest among all the generated voice notification events.

  Moreover, the priority determination part 603 respond | corresponds to the canceled audio | voice alert | reporting event (its event ID), when an audio alert event is canceled after it detects that the number of the audio alert | reporting events currently occurring is plurality. A comparison is made between the priority and the priority corresponding to the sound notification event that is occurring to determine its level. More specifically, it is confirmed whether or not the priority of the voice notification event that has been eliminated in comparison with the voice notification event that is occurring is the highest.

  The playback control unit 604 performs playback control of the audio file according to the number of audio notification events that are being detected 602 detected by the audio notification event detection unit.

  When the number of voice notification events that are occurring is one, the playback control unit 604 searches for and plays a voice file stored at an address corresponding to the voice notification event that is occurring.

  The reproduction control unit 604 performs reproduction control based on the comparison result by the priority determination unit 603 when there are a plurality of audio notification events that are occurring.

  When the priority determination unit 603 confirms that the priority corresponding to the newly generated voice notification event is the highest, the playback control unit 604 generates a voice notification event that is occurring other than the newly generated voice notification event. Check whether the audio file corresponding to is being played. If it is being reproduced, the reproduction is stopped, and the audio file stored at the address corresponding to the newly generated audio notification event is retrieved and reproduced. If not being played back, the audio file stored at the address corresponding to the newly generated voice notification event is searched for and played back. Thereby, the audio file corresponding to the audio notification event having the highest priority can be reliably reproduced.

  When the priority determination unit 603 confirms that the priority corresponding to the canceled audio notification event is the highest, the reproduction control unit 604 is reproducing the audio file corresponding to the canceled audio notification event. Check if it exists. If it is being reproduced, the reproduction is stopped, and the audio file stored at the address corresponding to the audio notification event having the highest priority among the audio notification events that are occurring is searched and reproduced. If it is not being reproduced, the audio file stored at the address corresponding to the audio notification event having the highest priority among the audio notification events that are occurring is searched for and reproduced. Thereby, when the voice notification event having the highest priority is canceled, an unreproduced audio file corresponding to the voice notification event that has not been canceled can be reliably played back.

1-4. Example of Operation of Blood Glucose Level Measuring Device Next, the operation of the blood glucose level measuring device 101 relating to audio file reproduction control when a voice notification event occurs will be described with reference to FIG.

  FIG. 8 is a flowchart showing the operation of the blood sugar level measuring apparatus 101 according to one embodiment of the present invention.

  When the control unit 402 detects that a new voice notification event has occurred, the control unit 402 causes the voice notification event detection unit 602 to check whether there are a plurality of voice notification events that are being generated (step S701). If there is one audio notification event that is occurring (NO in step S701), the control unit 402 causes the reproduction control unit 604 to reproduce the audio file corresponding to the newly generated audio notification event. As a result, a sound corresponding to the reproduced sound file is output from the sound output unit 112 (step S702). Then, the process ends.

  On the other hand, if there are a plurality of voice notification events that are occurring (here, two cases are illustrated) (YES in step S701), the control unit 402 notifies the priority determination unit 603 of the voice notification events that are occurring. In step S703, it is checked whether the priority of the voice notification event newly generated is the highest. If the priority of the newly generated voice notification event is the highest (YES in step S703), the control unit 402 causes the playback control unit 604 to respond to a voice notification event that is occurring other than the newly generated voice notification event. It is confirmed whether the audio file to be played is being reproduced (step S704).

  If there is an audio file being reproduced (YES in step S704), the control unit 402 causes the reproduction control unit 604 to stop reproducing the audio file (step S705). Then, the control unit 402 causes the reproduction control unit 604 to reproduce the audio file corresponding to the newly generated audio notification event, and the audio corresponding to the reproduced audio file is output from the audio output unit 112 (step S706). ). On the other hand, if there is no audio file being played back (NO in step S704), the process proceeds to step S706.

  After the above processing is completed, the control unit 402 causes the audio notification event detection unit 602 to confirm whether or not the audio notification event has been canceled (step 707). While the voice notification event is not canceled (NO in step S707), the process in step S707 is repeated. On the other hand, if the voice notification event is canceled (YES in step S707), the control unit 402 causes the priority determination unit 603 to set the priority of the voice notification event that has been canceled compared to the voice notification event that is occurring. It is confirmed whether it is the highest (step S708).

  If the priority of the canceled voice notification event is the highest (YES in step S708), the control unit 402 causes the playback control unit 604 to check whether the voice file corresponding to the canceled voice notification event is being played back. (Step S709). If playback is in progress (YES in step S709), the control unit 402 causes the playback control unit 604 to stop playback of the audio file being played back (step S710). Then, the control unit 402 causes the reproduction control unit 604 to reproduce the audio file corresponding to the sound notification event that is occurring, and the audio corresponding to the reproduced audio file is output from the audio output unit 112 (step S711). The process ends. On the other hand, if the audio file corresponding to the canceled audio notification event is not being reproduced (NO in step S709), the process proceeds to step S711.

  If the priority of the newly generated voice notification event is not the highest in the process of step S703 described above (NO in step S703), the process proceeds to the process of step S707 without reproducing the voice file.

  If the priority of the canceled audio notification event is not the highest among the audio notification events that are occurring in the process of step S708 described above (NO in step S708), the process ends without reproducing the audio file. To do. In the operation example of the present embodiment, the case where the number of sound notification events that are occurring is 2 is exemplified, but the processing flow can be appropriately changed corresponding to the case of 3 or more.

  As described above, in the embodiment of the present invention, when a voice notification event is newly generated or when the voice notification event is canceled, the highest priority voice among the voice notification events that are being generated. Only the audio file corresponding to the notification event can be reproduced. Thereby, it is possible to clearly indicate to the user a voice notification event that needs to be dealt with with the highest priority.

  In addition, only the audio file corresponding to the audio notification event having the highest priority among the audio notification events that are occurring is played back, and the audio files corresponding to the other audio notification events that are occurring are not played back. Can also be prevented.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various other configurations can be taken without departing from the gist of the present invention.
