Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Of course, the contents of the present invention are not limited to the contents of the following embodiments.

[1. First Embodiment]
[1.1 System appearance]
FIG. 1 is a diagram for explaining a method of using a sleep evaluation system when the biological information output apparatus of the present invention is applied. As shown in FIG. 1, the sleep evaluation system 1 includes a detection device 3 placed between the floor of the bed 10 and the mattress 20, and a processing device 5 for processing a value output from the detection device 3. It is prepared for.

When the user P who is the user is present on the mattress 20, the detection device 3 detects the body movement (vibration) of the user P via the mattress 20. Based on the detected vibration, the respiration (respiration rate within a predetermined time) of the measurement subject P is detected (output) as biological information.

In the present embodiment, the detected respiration (number) is transmitted wirelessly to the processing device 5 (for example, a computer). For example, the detection device 3 is integrally formed by providing a display unit or the like. Also good. Moreover, since the processing apparatus 5 may be a general-purpose apparatus, it is not limited to an information processing apparatus such as a computer, and may be configured by an apparatus such as a tablet or a smartphone.

Here, the detection device 3 is configured in a sheet shape so as to be thin. Thereby, even if it is placed between the bed 10 and the mattress 20, it can be used without making the person to be measured P feel uncomfortable.

In addition, the detection apparatus 3 should just detect respiration as a to-be-measured person's P biological information. In the present embodiment, respiration is detected based on body movement. However, for example, a breathing sound is detected using an audio sensor, a body movement of the measurement subject P is detected using an infrared sensor, or the like. An actuator with a gauge may be used.

[1.2 Functional configuration]
Then, the mechanism structure of the sleep evaluation system 1 is demonstrated using FIG. The sleep evaluation system 1 in the present embodiment has a configuration including the detection device 3 and the processing device 5, and each functional unit (processing) may be realized by any means other than the respiratory detection unit 200.

In the sleep evaluation system 1, a respiration detection unit 200, a storage unit 300, an input unit 400, and an output unit 500 are connected to the control unit 100 via a bus.

The control unit 100 is a functional unit for controlling the operation of the sleep evaluation system 1, and includes a control circuit necessary for the sleep evaluation system 1, such as a CPU. The control unit 100 implements various processes by reading and executing various programs stored in the storage unit 300. In the present embodiment, the control unit 100 operates as a whole, but is provided in each of the detection device 3 and the processing device 5.

The respiration detection unit 200 is a functional unit for detecting the measurement subject's respiration. In the present embodiment, it is a sensor unit for detecting vibration. The respiration of the measurement subject is detected from the vibration (body motion) detected by the sensor unit. Further, by using the sensor unit, it is possible to detect body movements other than breathing of the measurement subject P such as turning over and heartbeat.

The respiration detection unit 200 according to the present embodiment detects, for example, the vibration (body movement) of the person to be measured using a pressure sensor and detects respiration from the vibration, but the gravity center position (body movement) of the person to be measured using a load sensor. It is good also as detecting respiration by the change of, and you may detect based on the sound which a microphone picks up by providing a microphone. It suffices if the respiration of the person to be measured can be detected using any sensor.

The storage unit 300 is a functional unit that stores various data and programs for the sleep evaluation system 1 to operate. The control unit 100 implements various functions by reading and executing a program stored in the storage unit 300. The storage unit 300 is configured by, for example, a semiconductor memory, a magnetic disk device, or the like. Here, the respiration rate table 302 and the color bar table 304 are stored in the storage unit 300.

The respiration rate table 302 is a table in which the respiration rate output based on the respiration detected by the respiration detection unit 200 is stored. As shown in FIG. 3, the respiration rate table 302 stores the respiration rate in a predetermined time (hereinafter referred to as “respiration rate calculation time”) in time series. As an example, the respiration rate calculation time in this embodiment is “1 minute”.

Further, a plurality of respiratory rate tables 302 may be stored for each piece of identification information. By using the identification information, for example, it can be stored for each person to be measured, or even the same person to be measured can be stored separately for each measurement date.

The color bar table 304 is a table for determining a color, the number of divisions, and the like when creating and outputting a vital diary (sleep graph). As shown in FIG. 4, the color bar table 304 stores parameters.

Specifically, the color bar upper limit (for example, “28”) and the color bar lower limit (for example, “4”) are stored as the respiratory rate. Further, the number of divisions (for example, “7”) of the color bar is stored, and the color information (color) of each section is stored as color 1, color 2,. Here, the upper limit value and the lower limit value indicate the boundary between the abnormal value, and the same color is used when the upper limit value is equal to or higher than the lower limit value or lower.

Here, in this embodiment, color information is stored as a display pattern. The content of the color information may be stored as, for example, an RGB value (for example, “# 0000FF”) or may be stored as a color name such as “Blue”. Further, instead of color information, it may be halftone, or information specifying a color such as wavelength, density, color temperature, or the like.

In particular, there are various expression methods, but it is preferable that the colors are set so that periodic fluctuations and fluctuations with time are easy for the user. For example, the lower limit value is a color with a short wavelength (for example, blue), and the upper limit value is a color with a long wavelength (for example, red). Then, as the wavelength changes from the lower limit value to the upper limit value, transition is made from purple, blue, green, yellow, red, and the like.

In the case of monochrome, it may be expressed in shades. In this case, the darkness is gradually changed. In the case of monochrome, the upper limit value (lower limit value) color may be darkened and the reference value lightened so that the abnormal value can be clearly understood. Further, even if the color is not monochrome, it may be expressed by shading or color density (white → pink → red, etc.) when it is expressed by the same color system (for example, when expressed by a red color). .

The input unit 400 is a functional unit for a user to input an operation instruction or the like to the sleep evaluation system 1. An operation button (hardware switch) incorporated in the detection device 3 may be used, or a connected processing device 5 may be used.

The output unit 500 is a functional unit for outputting various information from the sleep evaluation system 1. The output unit 500 may be a liquid crystal display capable of color display or a color printer (printing apparatus) capable of color printing. Further, it may be a monochrome printer capable of printing in gray scale.

[1.3 Process flow]
Next, the flow of processing in this embodiment will be described with reference to FIG. This process is a process that is selected when outputting a vital diary (a graph showing the trend of respiratory rate as biological information).

The respiratory rate is detected in advance, the respiratory rate is stored in the respiratory rate table 302, and the color bar table 304 is also stored. And it is a process performed after inputting the schedule (range) output as a vital diary.

First, “1” is assigned to the variable n as an initial value (step S102). Next, the respiration rate (per unit section) is read from the respiration rate table 302 (step SS104). A color is determined according to the read respiratory rate (step S106).

Subsequently, the graph is displayed in the determined color (step S108). Specifically, it is displayed in a horizontally stacked state on the band of the date area. The band graph at this time is displayed according to the respiration rate for the display time.

Specifically, when the display time is “24 hours”, a vital diary based on the daily respiratory rate is displayed. By setting it to 24 hours, it is almost the same as the circadian rhythm of a person, and the fluctuation of circadian rhythm can be grasped. In addition, for example, visually confirm whether there is a rhythmic property according to the time taken as one line, such as a half-day rhythm when 12 hours are in one line, and a three-hour rhythm when 1 hour is in one line. It becomes possible to do. In the present embodiment, 24 hours is described as the display time.

The process is repeatedly executed from step S104 until reading of all the respiratory rates on the nth day is completed (step S110; No → step S104).

In addition, about reading here, you may read only within the set time, for example, and may read only the memorize | stored time. For example, when the time is not stored, it may be output that it is not a target.

When reading of the respiratory rate on the nth day is completed (step S110; Yes), 1 is added to n (step S112). Then, the drawing area is moved to the next area (step S114). Thereby, it is possible to display (print) a graph indicating a plurality of trends of biological information in one screen (one sheet).

Then, the process is repeatedly executed until all the schedules to be output as the pre-input vital diary are completed (Step S116; No → Step S104).

[1.4 Examples]
Next, specific examples will be described. First, FIG. 6 is an example of a display screen W100 for storing parameters in the color bar table 304. FIG. 6A illustrates a case where the set color is a gray scale, and FIG. 6B illustrates a case where the set color is a color.

The color bar upper limit value can be input to the region R100, and the color bar lower limit value can be input to the region R102. In the area R106, the number of color divisions can be input.

In the area R108, a color bar is displayed. At this time, the color of the normal value of the normal range is set to C102, and as it approaches the abnormal value, it is set to C104, C106, and C108.

Here, the normal range median is a value automatically determined from the set low value reference value and high value reference value in the present embodiment, but for example, a standard value is initially set as the normal range median. The low value reference value and the high value reference value may be automatically set from the value. In addition, about a color, you may set arbitrary colors and you may set the color of the same system | strain.

Here, as the color pattern to be set (color setting pattern), the following patterns can be considered.

(1) Color color setting pattern This is a pattern in which a user sets an arbitrary color pattern or sets a color that is easy to view. For example, as shown in FIG. 6B, the wavelength of the color changes from the low value reference value to the high value reference value, with purple (C164) being lower than the low reference value and red (C152) being higher than the high reference value. Set to. For example, an abnormal value can be easily identified visually by transitioning to blue (C162), light blue (C160), green (C158), yellow (C156), and orange (C154). This color setting pattern is effective for display devices such as computer displays capable of color display, tablets, and portable terminal devices, and printing devices capable of color output.

(2) Gray scale color setting pattern This is a color setting pattern that is easy to see when outputting to a monochrome printer capable of gray scale. For example, the median value of the normal range is set to a color system close to “white”, and the abnormal value (below the low reference value and above the high reference value) is set as “black”. Then, as the normal value approaches the abnormal value from the normal value of the normal range, the color is printed darker.

By using such a color pattern, it is possible to output a vital diary that is easy to view even when output by a monochrome printer (monochrome laser printer, monochrome multifunction peripheral, etc.).

These multiple color patterns need not be stored. However, by storing a plurality of color patterns, for example, an appropriate color is determined in step S106 of FIG.

The color pattern may be selected in advance, or the color pattern may be selected in advance after the output destination is determined. Further, by changing the number of divisions according to the output destination, for example, a color image is displayed in 10 levels, but a monochrome image may be displayed in 6 levels.

FIG. 7 is an enlarged view for explaining a vital diary output as an example in order to show a tendency of biological information. Here, the mark M102 is a wake-up mark. Displayed when the user gets up and wakes up. It should be noted that the user may enter the bed and wake up, or may be automatically determined.

After this, the color bars are displayed in chronological order. There are various methods for displaying the color bar. For example, a color may be determined and displayed for each time interval (for example, “22:33 to 22:37”) as in C202.

Also, for example, the color is determined and output for each unit section such that the section from t1 to t2 is “C206” and the section from t2 to t3 is “C206”. Here, if the respiration rate is the same (for example, “t3 to t4, t4 to t5, t5 to t6”), the same color (C204) is output.

FIG. 8 is a diagram showing an example of a vital diary. A graph showing the state for each date is drawn. On each date, a bed / wake-up mark is displayed, and a state based on the respiration rate is displayed as a color (pattern) of the graph.

Furthermore, in the case of the diagram of the present embodiment, the average value of the respiration rate is also displayed. As the average value of the respiration rate, for example, the average respiration rate in the set section is displayed. The set section may be a predetermined bedtime and a wake-up time (for example, “22:00 to 5:00”), or may use a time obtained from a bed / wake-up mark.

FIG. 9 is a specific display example of a vital diary. FIG. 9A is an example of a display screen W100 that displays a vital diary (respiration diary) showing the state of the measurement subject as a sample. This person to be measured is a person whose condition deteriorated and died at around 11/15 (Friday) 21 o'clock, and is the data in which the respiratory rate in this case is displayed by the method of the present invention. FIG. 9B is an example of a display screen W150 that displays a vital diary of a healthy person.

FIG. 9 shows a vital diary with a low reference value of 8 and a high reference value of 28. FIG. 10 shows a time-series scatter diagram corresponding to FIG.

Also, icons for switching various display states are displayed on the display screen. For example, taking FIG. 9A as an example, the icons in the region R102 are icons for displaying a list of data for one week, two weeks, and four weeks, respectively. Further, the icon of the region R104 is an icon for enlarging or reducing the target portion.

In addition, the icon in the region R106 is used to select whether the center of the screen is set to 12:00 or 0:00. If the center of the screen is midnight, the nighttime data, which is the sleeping time zone, is contained in one line and is easy to see.

In addition, the icon of the region R110 is an icon for changing the high price reference value. Further, the icon of the region R112 is an icon for changing the low value reference value. Further, the icon of the region R114 is an icon for switching whether to display a bedtime, a wake-up time, and a bedtime between the bedtime and the wake-up time.

In addition, the display screen W100 can be switched between a plurality of screens using tabs. Currently, the sleep diary (respiration diary) is displayed by selecting the tab T102.

The following explains how to use the vital diary (breathing diary). In FIG. 9 (a), green is the median normal range (the light portion of FIG. 9 (a)), red is the high value abnormal value (the dark portion of FIG. 9 (a)), and blue is the low value abnormal value (FIG. 9 ( a) is a dark portion), which increases as the color approaches from green to red, and decreases as it approaches blue.

In normal sleep, as shown in FIG. 9B, the respiratory rate tends to decrease toward the morning (yellow or green to light blue or blue increase, for example, the region of G152). In FIG. 9 (a), it can be seen that from 11/6 (Wed) to 9 (Sat), the respiratory rate tends to decrease toward the morning.

However, in 11/10, 11 there are more sections where the respiratory rate cannot be calculated due to an increase in body movement (white, light state in FIG. 9A, G102), and in 11/12, the respiratory rate is conversely in the morning. Increasing (G104 region).

The respiratory rate suddenly decreased from around 5 o'clock in the morning of 11/13 (region of G106), and after 11/14 continued to have a high respiratory rate (dark color state in FIG. 9 (a)), 11 / 15 shows that the fluctuation of the respiratory rate became severe, and it was found that he died after the respiratory rate decreased from around 19:00.

According to the present embodiment, such long-term fluctuation can be grasped at a glance, but it is difficult to grasp at a glance with a normal time series graph. Further, FIG. 9A shows an example of 10 days, but it is impossible to confirm a long-term fluctuation such as one month in a normal time series graph.

Thus, since the display area is limited in the time-series scatter diagram, it is difficult to know when the abnormal value occurs, and it is also difficult to check the fluctuation of the 24-hour period. On the other hand, these points can be understood visually in the vital diary in FIG.

Note that a plurality of color bars displayed in the vital diary can be switched. For example, as shown in FIG. 11, “for color” and “for gray scale” can be set on the color bar setting screen.

At this time, it is possible to switch arbitrarily according to the device that the output unit 500 outputs. For example, if a monochrome printer is used, if a gray scale color bar is used, a highly visible vital diary can be output.

Thus, according to the present embodiment, the measurer can grasp the biological information with the band graph for the display time. For example, when the display time is 24 hours, the lines are output as one line every 24 hours, so that it is possible to grasp the state (circadian rhythm) of the measurement subject that changes in a 24-hour cycle.

In addition, since a plurality of the band graphs are displayed in parallel, the measurer can make a judgment by comparing a plurality of states of the person to be measured. At this time, since the color and shading represent the level of the measured value, data can be displayed three-dimensionally in a two-dimensional display area, and long-term data can be listed in a small display area. Therefore, it is possible to confirm global changes and trends at a glance.

[2. Second Embodiment]
Next, the second embodiment will be described. The second embodiment is an embodiment in which the vital diary displayed in the first embodiment is displayed together with the sleep diary indicating the sleep state. That is, as the measurement subject's sleep state, bed leaving, awakening (in bed), and sleep (in bed) are determined and displayed as a sleep diary.

Here, as a method of determining the sleep state of the person to be measured, the sleep state may be determined by vibration detected by the respiration detection unit 200, or other sleep state determination means (for example, other vibration sensor or infrared sensor). It may be determined by providing a means for determining the sleep state by sound detection or the like.

The color log of the vital diary displayed in the first embodiment and the sleep diary are displayed in parallel. Here, FIG. 12 schematically shows an enlarged view for explaining a state in which the vital diary and the sleep diary are displayed in parallel.

As shown in FIG. 12, information for one day is displayed in the region R300. In this area, the color bar of the vital diary is displayed in R302 and the sleep diary is displayed in R304. In the sleep diary, a bed mark M302 and a wakeup mark M304 are displayed. Also, a bed leaving mark M306 indicating that the user has left the bed during sleep is displayed.

The sleep diary has color bars such as C302 and C308 indicating awakening (for example, displayed in yellow), C304 indicating sleep (for example, displayed in blue), and C306 indicating leaving the bed (for example, displayed in white). R304 is displayed.

Thus, in this embodiment, the vital diary and the sleep diary are displayed in parallel. That is, the following effects can be expected by displaying the vital diary based on the detected biological information and the sleep diary in parallel.

First, when the biological information is not acquired, it can be determined that there is no problem if the user is in bed, and it can be determined that there is a body movement if the user is in bed. In addition, when the biological information is not detected even though the measurement subject is sleeping, it is determined that the measurement conditions are not good (for example, the mattress is too wide or too thick). be able to.

Even if it is determined that the biological information is abnormal, if it is immediately after getting out of bed or just before getting out of the bed, fluctuation of biological information due to body movement (for example, increase in respiratory rate, heart rate) Increase). In addition, when the biological information is abnormal in spite of stable sleep (for example, long sleep duration), there is a risk of a disease such as an increase in respiratory rate and heart rate due to sleep apnea.

In addition, by displaying in parallel with the vital diary and sleep diary, it is easy to catch the tendency of the respiratory rate and heart rate to rise before awakening, and whether the respiratory rate and heart rate are falling during sleep There is also an effect that it is easy to compare the difference in biological information during awakening. Further, during sleep and REM sleep, the respiratory rate and heart rate vary greatly, and it is easy to obtain a high value compared to the previous and subsequent values. Therefore, there is an effect that REM sleep and non-REM sleep can be roughly grasped.

In addition, as the display of the sleep diary, by switching the size of the display area, it may be possible to confirm both the sleep state of the measurement subject and the fluctuation of the biological information. By making it smaller, fluctuations in biological information may be mainly confirmed. Moreover, it is good also as switching these displays.

For example, as shown in FIG. 13, the sleep diary may be displayed as a region R402 in a superimposed manner on a part of the color bar of the vital diary of R400. That is, the display area of the sleep diary may be reduced or displayed on a part of the color bar of the vital diary. In this case, since the vital diary is conspicuously displayed as compared to FIG. 12, it is possible to easily grasp the daily tendency of the biological information.

Moreover, it is good also as a structure which switches the display / non-display of a sleep diary. If the sleep diary is not displayed, the same content as described in the first embodiment can be realized.

Example screens in this embodiment will be described with reference to FIG. FIG. 14A shows an example screen W200 in which a vital diary and a sleep diary are displayed in parallel. A band graph is displayed in the region R500 as a vital diary, and a band graph is displayed in R502 as a sleep diary. In addition, the sleep diary displays a bed mark M500 and a bed mark M502 indicating the bed and the bed of the measurement subject. The person to be measured (measurement person) may arbitrarily display the bed and wake-up, or may automatically display from the sleeping state. In addition, when there is a get-off between getting up and getting up, a get-off mark M504 is displayed. The bed leaving mark M504 may also be automatically displayed, and the person to be measured (measuring person) may be arbitrarily displayed.

In addition, the display such as the bed mark M500, the wake-up mark M502, and the bed leaving mark M504 are displayed in the band graph of the sleep diary in the present embodiment, but may be displayed in the band graph of the vital diary. Further, display / non-display of each mark may be arbitrarily switched.

FIG. 14B is a diagram showing a screen example W210 when priority is given to the list of vital diaries. A band graph of the vital diary is displayed in the region R510, and the sleep diary is displayed as a region R512 in a superimposed manner on the band graph. In the present embodiment, the sleep diary is only required to be visible to the height of the band graph of the vital diary.

Also, the height of the sleep diary may be changed by the measurer. For example, when priority is given to a sleep diary, the sleep diary may be displayed in a wide range (that is, the appearance is a state where a vital diary is superimposed on the sleep diary).

Thus, according to this embodiment, since the measurer can confirm the vital diary and the sleep diary together, it is possible to grasp the trend of the biological information of the measurement subject in association with the sleep state. Become.

[3. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also included in the present invention. It is.

In the above-described embodiment, “respiration rate” is used as one type of biological information of the person to be measured, but other biological information such as heart rate and body movement may be used.

In the embodiment described above, the sheet-type detection device 3 has been described as a method for detecting the biological information (respiration) of the measurement subject. However, the biological information of the patient is detected by other methods. Also good. For example, a radio wave type detection device may be provided on the bedside, the movement of the patient may be detected by the radio wave, and the respiratory rate may be obtained therefrom.

Moreover, in this embodiment, a vital diary (report) should just be output, and not only processing is performed by the detection device 3 and the processing device 5, but also, for example, the respiratory rate is managed on the cloud and processed by the server. It can also be realized as a service for displaying vital diaries.

In this case, the output unit 500 may be directly output by a color printer or the like, or may be displayed on a smartphone screen or the like.

In the above-described embodiment, the detection device 3 and the processing device 5 may be configured as separate devices or may be the same device. Moreover, the processing apparatus 5 may acquire in real time as a timing which acquires a respiration rate, and may acquire it collectively. For example, at the stage of acquiring a vital diary, it may be acquired by the detection device 3 or may be acquired at regular intervals.
