FIG. 1 is a schematic configuration diagram of a sleep diary creation device (1) according to the first embodiment. The sleep diary creation device (1) includes a biological information detection device (biological information detection unit) (10) and a controller (control device) (20). The biological information detection device (10) is a means for detecting physiological information of a person (living body), and can detect at least one of physiological information such as breathing, heartbeat, and body movement during sleep.

  The living body information detection device (10) is used so that a person sleeps under a sheet (not shown) covering a mattress or mattress (2), in other words, the mattress or mattress (2). It is configured in a thin mat shape so that it can be used directly. Specifically, the biological information detection device (10) includes a pressure sensitive part (11) configured by arranging a plurality of air passages (12), and an air passage (12) of the pressure sensitive part (11). ) Connected to the collecting pipe part (13) and a pressure detecting part (14) connected to the collecting pipe part (13), and the pressure sensitive part (11) is laid directly under the sheet. ing. The pressure detector (14) is configured to detect a pressure change in the air passage (12) via the collecting pipe (13).

T). The tube (T) is made of a flexible material such as silicon or polyethylene. These tubes (T) having a diameter of about 1 mm to 3 mm are selected. As an example, a silicon tube (T) having an outer diameter of 3 mm, an inner diameter of 1.5 mm, and a wall thickness of 0.75 mm, which is bent into a U-shaped tube, is connected to the collecting pipe section (13) with a tube interval of 10 mm. it can. Further, in order to maintain the approximate positional relationship between the tubes (T), each tube (T) is knitted with the warp (15).

  A joint portion (not shown) for each tube (T) is formed in the collecting pipe portion (13), and the tube (T) is connected to the collecting pipe portion (13) by press fitting. The length of the tube (T) is about 1 m when folded into a U-shaped tube (the width dimension on the left and right in the figure is 1 m), the length of the collecting tube (13) is about 50 cm, and people lie on the bedding. The approximate chest position can be covered as a detection area.

  The distal end (upper end in the figure) of the collecting pipe part (13) is sealed, and an acoustic microphone (pressure detection part) (14) is installed on the proximal end (lower end in the figure) side. As the pressure detection unit (14), a pressure sensor may be used instead of the acoustic microphone.

  In this configuration, the pressure-sensitive part (11) is composed of a plurality of relatively short tubes (T), on which a person goes to sleep, so that the tube associated with human breathing, heartbeat, body movement, etc. The pressure change in T) is transmitted to the pressure detector (14). In addition, since the pressure-sensitive part (11) is configured by arranging a plurality of flexible and thin tubes (T) at a relatively narrow pitch, it is configured so that a foreign object sensation is unlikely to occur when a person lies on it. ing.

  Furthermore, by arranging a plurality of flexible tubes (T) to form the pressure sensitive part (11), the weight load of the person lying on the top is distributed and applied to each tube (T). Therefore, the tube (T) is not crushed during use without pressurizing the air passage (12) in the tube (T). Note that the difficulty of crushing the tube (T) can be adjusted by the diameter and thickness of the tube (T) and the pitch of the array, but according to experiments, it is flexible and thin enough not to feel a foreign object feeling during use. Even when the tube (T) is used without applying pressure, it has been confirmed that it does not collapse with weight.

  The controller (20) is connected to the acoustic microphone (14) via a wire harness (16). As shown in FIG. 3 which is a block diagram of the sleep diary creation device (1), the controller (20) is a sleep information determination unit that determines sleep information based on physiological information detected by the biological information detection device (10). (21), a sleep diary generation unit (22) that creates a sleep diary from the determined sleep information, and a display unit (23) that displays the created sleep diary.

  The sleep diary generator (22) is configured to store sleep histories for a plurality of days. The display unit (23) can display the sleep history for the plurality of days as a sleep diary, and can switch between the sleep history for the plurality of days and the sleep history for the day. Is possible.

  As shown in FIGS. 4 and 5, the controller (20) includes a casing (24) provided with the display unit (23), and the sleep information determination unit (21) and the sleep unit are provided in the casing (24). A diary generator (22) is built in. An operation unit (25) is provided on the surface of the casing (24). The operation unit (25) includes a measurement / stop button (25a) for switching between measurement and stop, a diary button (25b) for performing "diary display" for displaying a sleep history for several days, A memory button (25c) for performing “memory display” that displays the sleep history for the day, a setting button (25d) for performing various settings of the controller (20), a diary display, and a memory display. A switching button (25e) for switching is provided.

  FIG. 4 shows a state where “diary display” is performed on the display unit (23). In the example of the figure, the sleep history for 5 days is displayed as a sleep diary, and the sleep time, wake-up time, mid-wake time, sleep level (approximate sleep depth), etc. can be understood. FIG. 5 shows a state in which “memory display” is performed on the display unit (23). In the example of the figure, the history of heart rate variability for one day is displayed, but instead of such a history of physiological information, the quality of sleep of the day obtained by analyzing physiological information is displayed, The total sleeping time of the day may be displayed.

-Driving action-
Next, the operation of the sleep diary creation device (1) will be described.

  The biological information detection device (10) is laid directly under the sheets as described above, and the pressure in the tube (T) changes due to the breathing, heartbeat, body movement, etc. of the person sleeping on it. To do. When the pressure in the tube (T) changes, the pressure change is picked up by the acoustic microphone and transmitted to the controller (20). In the controller (20), the sleep information determination unit (21) determines sleep information based on the pressure change. And by this sleep information, various information about sleep, such as whether a person fell asleep, awakened midway, or got up, is obtained, and sleep history for multiple days is stored in the sleep diary generation unit (22) A sleep diary is created. The sleep diary created in this way is displayed as shown in FIGS. 4 and 5 on the display unit (23).

-Effect of Embodiment 1-
According to the first embodiment, a sleep diary can be automatically created and displayed simply by laying a mat-like biological information detecting device (10) in the bedding and lying on the subject. Thus, in this embodiment, since a sleep diary can be created without restraining a test subject's body, a test subject can sleep comfortably.

  In particular, by detecting physiological information such as breathing, heartbeat, and body movement with the biological information detection device (10), it is possible to reliably determine sleep information such as sleep time and wake-up time from changes in these physiological information. It is possible to create an accurate and detailed sleep diary. In addition, breathing is used to detect the presence of snoring and sleep apnea syndrome, heartbeat is used to detect the degree of stress or relaxation, and body movement is used to detect sleep / wake or REM (REM) sleep / non-REM (NREM) sleep. Since it can be used, it is possible to record detailed information that could not be recorded by a conventional sleep diary.

  In addition, since the sleep history for multiple days stored in the sleep diary generator (22) is displayed as a sleep diary on the display unit (23), it is possible to easily grasp the sleep habits of the subject. In addition, since the sleep history for a plurality of days and the sleep history for one day are switched and displayed on the display unit (23), it is also possible to obtain detailed information for each day regarding sleep.

  Furthermore, the mat-like biological information detection device (10) is provided with a pressure-sensitive part (11) configured by arranging the air passages (12), and pressure changes in the air passages (12) are detected. (14) so that the pressure change in the air passage (12) based on changes in the heartbeat, breathing, body movement, etc. of the subject lying on the pressure sensitive part (11) is reliably detected. It is possible to detect and accurately determine sleep information. Therefore, a more accurate sleep diary can be created.

  In addition, the flexible and thin tubes (T) such as silicon and polyethylene are bent into a U-shaped tube and arranged in parallel to each other to form the pressure-sensitive part (11). A biological information detection device (10) that is highly flexible and flexible, and that does not give a sense of foreign matter as a bedding when laid directly under a sheet can be configured. In addition, by appropriately setting the arrangement pitch of the tubes (T), it is easy to obtain an opening ratio that does not impair the air permeability even when the tube (T) is placed directly under the sheets.

  Furthermore, the tube (T) constituting the air passage (12) can be made not to be completely crushed by weight load during use by appropriately selecting the material, diameter and thickness, If the tubes (T) are arranged at a fine pitch, the load is dispersed, and a high detection capability can be realized while having a flexible configuration with little foreign matter feeling.

  In addition, the end of the thin tube (T) is connected to the collecting pipe section (13) having higher conductance, and the pressure detecting section (14) such as a pressure sensor or an acoustic microphone is connected to the collecting pipe section (13). Since it is connected, it is possible to detect a pressure change with a small signal loss while ensuring a necessary pressure transmission area. For this reason, not only large body movements such as turning over, but also slight movements and minute vibrations such as breathing, heartbeats, and snoring can be reliably detected.

  In addition, even if the tube (T) is not crushed in normal use, the corners of a hard and heavy object may hit and crush may occur due to load concentration in one place, but multiple tubes (T) Are arranged in parallel, even if such crushing occurs in several places, it is possible to avoid a fatal influence on the measurement due to pressure / vibration transmission from the adjacent tube (T). Therefore, even in such a case, it is possible to prevent the detection accuracy from deteriorating.

-Modification of Embodiment 1-
In the first embodiment, the acoustic microphone (pressure detection unit) (14) is provided integrally with the biological information detection device (10). However, the pressure detection unit (14) may be built in the controller (20). . Even if it does in this way, there can exist an effect similar to the said Embodiment 1. FIG.

<< Embodiment 2 of the Invention >>

  FIG. 6 is a plan view of the biological information detecting device (10), and FIG. 7 is a perspective view showing a joint structure of the pressure sensitive part (11) and the collecting pipe part (13). In the second embodiment, a polyethylene tube (T) having an outer diameter of 1.0 mm and an inner diameter of 0.5 mm is used for the air passage (12) of the pressure-sensitive part (11). Further, as the collecting pipe portion (13), a polyethylene laminate film (sheet material) (17) formed into a cylindrical shape by heat sealing is used.

  Since the collecting pipe portion (13) must not be crushed, as shown in FIG. 7, a space securing structure member (18) (for example, a U-shaped or C-shaped extruded material) is incorporated therein. Since the collecting pipe part (13) can be taken out of the bedding, thinness and flexibility are not essential.

  In this configuration, the heat seal of the sheet material (17) can also be used to connect the tube (T) and the collecting pipe part (13), and the formation of the collecting pipe part (13) and the connection of the tube (T) are simultaneously performed. It can be carried out. That is, the sheet material (17) can be used as a joining member for joining the tube (T) of the pressure-sensitive part (11) and the collecting pipe part (13). If such a manufacturing method is adopted, it is slightly difficult to ensure perfect airtightness, but it is possible to improve the airtightness by taking a wider width of the sealing part, and it is not always perfect airtightness. Is not necessary, so it is easy to make the detection function not problematic.

<< Other Embodiments >>
The present invention may be configured as follows with respect to the above embodiment.

  For example, in the above embodiment, the tube (T) is U-shaped and has one collecting pipe part (13). However, two collecting pipe parts (13) are provided at both ends of the straight tube (T). May be.

  Further, the collecting pipe portion (13) may be provided as one, and a plurality of straight tubes (T) may be connected. In that case, it is desirable that the end of the tube (T) opposite to the collecting pipe portion (13) is closed from the viewpoint of preventing the signal from being lowered, but it can be used as an open end. For this reason, complete hermetic sealing is not necessary, and quality and manufacturing problems can be alleviated.

  Further, as shown in the schematic structure of FIG. 8, the pressure-sensitive part (11) of the biological information detection device (10) arranges tubes (T) bent into, for example, a U-shape in a lattice shape, and each tube ( You may make it connect the open end of T) to the collection pipe part (13) made into L shape.

  In addition, the pressure-sensitive part (11) of the biological information detection device (10) is configured by using a plurality of tubes (T), and is a plan view of FIG. As shown in FIG. 9B, a plurality of air passages (12) may be formed between the two sheets (19) that are overlapped and joined. That is, the pressure-sensitive portion (11) may be configured using a so-called air mat configuration.
