[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as those in reality. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed descriptions thereof will be omitted as appropriate.

[0009] (First embodiment) FIG. 1 is a schematic perspective view illustrating an example of electrically powered furniture including a biological information collecting device according to the first embodiment. 1, the motorized furniture 310 is, for example, a bed. The motorized furniture 310 includes a bottom 71. A mattress is provided on the bottom 71. A user of the motorized furniture 310 lies on the mattress.

[0010] The electrically powered furniture 310 is used, for example, in a hospital or a nursing home. The electrically powered furniture 310 may also be used, for example, in a home.

[0011] In this example, the bottom 71 includes a movable section 70. The movable section 70 includes, for example, a back section 70a, a knee section 70b, a leg section 70c, and a height change section 70h. The height change section 70h is, for example, a bed lift. As in the example of FIG. 1, the movable section 70 may further include a head section 70d. The angles of the multiple sections included in the bottom 71 (the back section 70a, the knee section 70b, the leg section 70c, and the head section 70d) relative to each other can be changed.

[0012] For example, a bottom 71 is provided on a frame 75. In this example, casters 70g are provided under the frame 75. The casters 70g may be omitted and changed to "legs."

[0013] The electrically powered furniture 310 is provided with a control device 311. The control device 311 can control the movable part 70 of the electrically powered furniture 310. The control device 311 is, for example, a remote controller for the electrically powered furniture 310. The control device 311 is, for example, a hand switch.

[0014] The control device 311 is provided with an operation reception unit 20 (such as a button or a touch panel). The operation reception unit 20 receives operations from a user. When the user operates the operation reception unit 20, for example, the movable unit 70 and the like are controlled.

[0015] The control device 311 may have various functions such as a function for turning on and off lights, a function for calling a caregiver or caregiver, or a function for turning on and off the power.

[0016] In this example, a control circuit 43 is provided. The control device 311 is connected to the control circuit 43 by a cable 15. The operation of the control circuit 43 causes the above-mentioned movable part 70 to operate.

[0017] In this example, a bedside terminal 47 is provided. The bedside terminal 47 may display, for example, the state of the bed (for example, the angle and height of the bed bottom, etc.). The bedside terminal 47 may also display the state of the user, etc.

[0018] In the embodiment, a sensor 62 is provided. The sensor 62 detects a biosignal of the user. The biosignal includes a body movement of the user. The biosignal includes, for example, at least one of a respiration rate of the user and a heart rate of the user.

[0019] 1, the sensor 62 is provided on the bottom 71. The sensor 62 detects, for example, the force associated with the breathing and heartbeat of the user, thereby detecting the breathing rate, heart rate, and the like.

[0020] FIG. 2 is a schematic diagram illustrating the sensor 62. As shown in FIG. 2, the sensor 62 includes a communication unit 62c and a sensor unit 62d. A biological signal S62 is detected by the sensor unit 62d. The obtained biological signal S62 is supplied to the communication unit 62c. Thus, in this example, the sensor 62 outputs biological information BS0.

[0021] 3(a) to 3(d) are schematic diagrams illustrating a sensor 62 included in the biological information collection device according to the embodiment. Fig. 3(a) is a cross-sectional view of an example of the sensor 62. Fig. 3(b) is a plan view of an example of the sensor 62. Fig. 3(c) is a perspective view illustrating the arrangement of the sensor 62. Fig. 3(d) is a side view illustrating the arrangement of the sensor 62.

[0022] 3(a), in this example, the sensor 62 includes a first plate 62p and a second plate 62q. The second plate 62q faces the first plate 62p. These plates may be sheet-shaped.

[0023] The second plate 62q includes a support protrusion 62s. The support protrusion 62s faces the outer edge of the first plate 62p. The first plate 62p includes an inner part inside the outer edge. An air container 62r is provided between the inner part and the second plate 62q. In this example, a groove 62t is provided in the second plate 62q. The air container 62r is provided in a space (a divided space) formed by the groove 62t. One end of a signal line 62u is connected to the air container 62r. ​​The other end of the signal line 62u is connected to the detection circuit 62v.

[0024] 3(b), the support protrusions 62s face parts of the outer edge of the first plate 62p. In this example, the support protrusions 62s are provided at the four corners of the first plate 62p. The sensor 62 is sheet-shaped or plate-shaped.

[0025] As shown in FIG. 3( c ), the above-mentioned sensor 62 is placed on the bottom 71 .

[0026] 3(d), the sensor 62 is placed on the bottom 71, and a mattress 76 is placed on top of the sensor 62. A user 81 lies on the mattress 76.

[0027] For example, a force corresponding to the body movement of the user 81 is applied to the air container 62r. ​​This force includes, for example, vibration. The force (or a characteristic corresponding to the force) applied to the air container 62r is detected by the detection circuit 62v. For example, a pressure detector is provided in the air container 62r, and a signal (detection result) obtained by the pressure detector is supplied to the detection circuit 62v. For example, a microphone is provided in the air container 62r, and a signal (detection result) obtained by the microphone is supplied to the detection circuit 62v. For example, an output (signal) of the detection circuit 62v is supplied to the control circuit 43. In the control circuit 43, the state of the user 81 (getting out of bed, sleeping, awake, etc.) is estimated. Alternatively, in the detection circuit 62v, the state of the user 81 (getting out of bed, sleeping, awake, etc.) may be estimated based on at least one of the detected force and the temporal change of the force. The state of the user 81 may include getting up, sitting on the edge of the bed (for example, a state of preparing to get out of bed), getting out of bed, falling asleep, sleeping, or awake.

[0028] In the sensor 62, the first plate 62p is disposed, for example, on the body side of the user 81. The second plate 62q is provided, for example, on the support side. A deformable air container 62r for detecting air pressure is provided between the centers of the first plate 62p and the second plate 62q. A groove 62t for mounting the air container 62r is provided in the center of the second plate 62q. The support protrusions 62s protrude in a direction from the second plate 62q toward the first plate 62p. The support protrusions 62s support the four corners around the first plate 62p. For example, the support protrusions 62s constantly support the first plate 62p in a horizontal state (normal state).

[0029] In the embodiment, the sensor 62 may have various modifications.

[0030] Next, a description will be given of processing of biological information executed by the biological information counting device 100 according to the embodiment. FIG. 4 is a block diagram illustrating the biological information counting apparatus 100 according to the embodiment. 4, the biological information counting device 100 includes a sensor 62, a calculation processing unit 101, and a memory 140. The calculation processing unit 101 includes a biological data calculation unit 110, an activity amount output unit 120, a first data processing unit 130, and the memory 140.

[0031] The biometric data calculation unit 110 extracts vibration components of biometric data from the biometric information BS0 sent from the sensor 62 at predetermined intervals. According to the embodiment, the predetermined interval is one minute. One minute is an example. The biometric data calculation unit 110 outputs the average value of the vibration components of the extracted biometric information BS0 for one minute as biometric data to the first data processing unit 130. The biometric data is, for example, heart rate data indicating the heart rate. The biometric data is, for example, respiratory rate data indicating the respiratory rate.

[0032] The activity amount output section 120 includes an activity amount calculation section 121 , a sleep determination value calculation section 122 , and a sleep state determination section 123 .

[0033] The activity amount calculation unit 121 calculates the amount of activity of the sleeper for each sampling unit time based on, for example, the vibration of the biological information BS0 detected by the detection circuit 62v. As a specific example, the output of the sensor 62 is continuously measured at a sampling period of 16 times per second (960 times per minute). A predetermined measurement threshold (upper limit and lower limit) is set in advance for the measurement value of the sensor 62. The activity amount calculation unit 121 counts the number of times the measurement value exceeds the measurement threshold for each minute. The activity amount calculation unit 121 sequentially outputs the counted activity amount (0 to 960) to the sleep determination value calculation unit 122 and the first data processing unit 130. The activity amount is a numerical value (0 to 960) that indicates how much the user 81 on the bed moved his / her body. The activity amount is related to the frequency and intensity of the body movement of the user 81. If the activity amount is large, it means that the user 81 moved his / her body frequently and greatly on the bed.

[0034] The sleep determination value calculation unit 122 may calculate, for example, the sum of the activity amount at a first time (e.g., the current time) and the activity amount calculated at a second time (e.g., a time before the current time) multiplied by a correction coefficient weighted according to time as the sleep determination value.

[0035] For example, the sleep state determination unit 123 determines the state as awake when the sleep determination value exceeds a predetermined threshold value, or may determine the state as asleep when the sleep determination value does not exceed the predetermined threshold value.

[0036] The biological information collecting device 100 distinguishes between a sleeping state and an awake state based on the amount of activity as well as the time series change of the amount of activity. For example, the biological information collecting device 100 does not determine an awake state even if there is a temporary body movement. The biological information collecting device 100 determines an awake state when the body movement continues to a certain extent.

[0037] The first data processing unit 130 compares the amount of activity with a first threshold. The amount of activity is received from the activity amount calculation unit 121. The first threshold is, for example, set in advance. If the amount of activity exceeds the first threshold, the first data processing unit 130 determines that the corresponding biological data is "invalid". If the amount of activity does not exceed the first threshold, the first data processing unit 130 determines that the corresponding biological data is "valid". The biological data determined to be "invalid" is discarded. The first threshold is set appropriately. According to the embodiment, the first threshold is set to "zero". Since the first threshold is "zero", the first data processing unit 130 extracts only biological data at rest. The extracted biological data is output to the memory 140.

[0038] The memory 140 stores the biometric data that is output from the first data processing unit 130 as “valid”.

[0039] The display unit 150 displays the biometric data stored in the memory 140. The display unit 150 may be included in the biometric information collection device 100, for example. The display unit 150 may be a display unit of a server communicatively connected to the biometric information collection device 100, for example. The display unit 150 may be a display unit of a terminal device communicatively connected to the biometric information collection device 100, for example.

[0040] FIG. 5 is a diagram illustrating an example of biological data displayed on the display unit 150. Heart rate data and the amount of activity when the amount of activity is "zero" are displayed on the display unit 150. According to the embodiment, five hours of heart rate data are displayed. This is heart rate data when the amount of activity is "zero". Therefore, the amount of activity is not displayed on the display unit 150. In addition, the average heart rate value per minute falls within a range of approximately 70 to 85 beats per minute.

[0041] FIG. 6 is a display example of heart rate data when the first data processing unit 130 is not provided, shown as a reference example.

[0042] As shown in Fig. 6, the display unit 150 displays heart rate data when the amount of activity is not "zero". Unreliable data that is affected by the patient's body movements and data that cannot be used as resting data due to the patient's own body movements are also displayed. There is some data where the average for one minute is not within the range of approximately 70 to 85 beats per minute.

[0043] FIG. 7 is a diagram illustrating an example of biological data displayed on the display unit 150. Respiratory rate data when the amount of activity is "zero" is displayed on the display unit 150. According to the embodiment, respiratory rate data for five hours is displayed. This is respiratory rate data when the amount of activity is "zero". Therefore, the amount of activity is not displayed on the display unit 150. In addition, the average respiratory rate value per minute falls within a range of approximately 11 to 19 breaths.

[0044] FIG. 8 is a reference example showing a display example of respiratory rate data when the first data processing unit 130 is not provided.

[0045] As shown in Fig. 8, display unit 150 displays respiration rate data for which the amount of activity is not "zero." Unreliable data that is affected by the patient's body movements and data that cannot be used as resting data due to the patient's own body movements are also displayed. There is some data where the average per minute does not fall within the range of approximately 11 to 19 breaths.

[0046] According to the embodiment, the biological information collecting device 100 can use the amount of activity calculated by the activity amount calculation unit 121 to remove unreliable biological data from the biological information that has been affected by the patient's body movements and biological data that cannot be used as resting data due to the patient's body movements in the data processing unit. The biological information collecting device 100 can improve the detection accuracy of the patient's biological data at rest. With this configuration, it is possible to extract only biological data that should be taken into consideration in observing the biological data (for example, when the patient is at rest, a portion of the biological data of interest that is not affected by disturbances, etc.) and perform collection suited to the purpose of observation.

[0047] Second embodiment In the second embodiment, a first data processing unit filters a plurality of pieces of biometric data. In the second embodiment, the configuration described in relation to the first embodiment may be applied to the extent that it is technically possible.

[0048] According to the embodiment, the first data processing unit 130 discards the biometric data next to the biometric data determined to be "invalid" in the first embodiment. Discarding the next biometric data is an example. The first data processing unit 130 may discard a plurality of data succeeding the biometric data determined to be "invalid".

[0049] 9 and 10 are examples of display of biological data displayed on the display unit 150 by the biological information counting device according to the embodiment. In FIG. 9, heart rate data is displayed when the activity amount is "zero". According to the embodiment, the next heart rate data of the data of which the activity amount is not zero is also discarded. Compared to FIG. 5, more heart rate data is discarded. In FIG. 10, respiration rate data is displayed when the activity amount is "zero". According to the embodiment, the next respiration rate data of the data of which the activity amount is not zero is also discarded. Compared to FIG. 7, more respiration rate data is discarded.

[0050] Therefore, when the amount of activity exceeds the first threshold, the biological information collecting device 100 discards the biological data corresponding to the amount of activity and the next calculated biological data in succession. The biological information collecting device 100 can discard data that is estimated to be unable to be accurately measured due to the influence of disturbances, etc. With this configuration, it is possible to extract only biological data that should be taken into consideration in the observation of biological data (for example, when the patient is at rest, a portion of the biological data of interest that is estimated to be unaffected by disturbances, etc.) and perform collection suited to the purpose of observation.

[0051] Third embodiment In the third embodiment, a setting unit that sets the operation of the first data processing unit is provided. In the third embodiment, the configurations described in relation to the first embodiment may be applied to the extent that they are technically possible.

[0052] FIG. 11 is a block diagram illustrating the biological information counting apparatus 100 according to the embodiment. 11, in the biometric information counting device 100, a setting unit 131 is provided in a first data processing unit 130. The setting unit 131 sets which operation the first data processing unit 130 will perform. The setting unit 131 includes an operation stopping unit 132, a first processing unit 133, and a second processing unit 134.

[0053] When the operation stop unit 132 is set, the first data processing unit 130 stops operating. In this case, filtering of biological data is not performed. When the first processing unit 133 is set, when the amount of activity exceeds a first threshold, the first data processing unit 130 is caused to perform a process of discarding biological data corresponding to the amount of activity. When the second processing unit is set, when the biological data is discarded, the first data processing unit 130 is caused to perform a process of discarding multiple biological data succeeding the biological data.

[0054] The biological information counting device 100 is provided with an operation unit 160. The operation unit 160 sets which of the operation stop unit 132, the first processing unit 133, and the second processing unit 134 is to operate the first data processing unit 130. The operation unit 160 may be provided outside the biological information counting device 100.

[0055] By operating the operation unit 160 to select the operation of the first data processing unit 130, the biometric information collection device 100 can select the biometric data to be output with appropriate accuracy according to the purpose of using the biometric data and the environment in which the biometric data is measured. For example, the operator sets the operation stop unit 132 using the operation unit 160. This prevents the biometric data from being filtered. The biometric information collection device 100 can detect abnormalities in the breathing and heart rate of the non-observer in real time. For example, the operator sets the first processing unit 133 or the second processing unit 134 using the operation unit 160. This allows the biometric information collection device 100 to more accurately observe the biometric data of the user 81 at rest.

[0056] The memory 140 may also store setting information indicating which operation of the setting unit 131 was set to collect the biometric data, together with the biometric data.

[0057] When displaying biometric data, the display unit 150 may display the settings for tabulating the biometric data. FIG. 12 is an example of display of setting information. In the display area 150a at the upper right of FIG. 12, it is displayed that the biometric data displayed on the display unit 150 is set to "no data filtering (stopped operation)". As settings for tabulating the biometric data displayed in the display area 150a, other settings for tabulating the selected biometric data, such as "filtered display of data at rest (discarded data during activity)" (corresponding to the first embodiment described above) and "filtered display of data at rest (discarded two sample data after activity)" (corresponding to the second embodiment described above), may be displayed on the display unit 150. With this configuration, the observer of the data can select the tabulation setting of the biometric data that matches the purpose of the observation and intuitively grasp whether the selection is reflected in the display unit 150 during the observation, and the biometric information tabulating device 100 can further improve the convenience of the operator.

[0058] (Fourth embodiment) In the fourth embodiment, the biological information collecting apparatus has a second data processing unit. In the fourth embodiment, the configuration described in relation to the first embodiment may be applied to the extent that it is technically possible.

[0059] FIG. 13 is a block diagram illustrating the biological information counting apparatus 100 according to the embodiment. As shown in FIG. 13, a second data processing unit 135 is provided between the first data processing unit 130 and the memory 140.

[0060] The second data processing unit 135 executes a thinning process on the biometric data output from the first data processing unit 130. It is preferable that the second data processing unit 135 executes the thinning process on the heart rate data among the biometric data.

[0061] For example, when the amount of fluctuation Δ of the heart rate data between samplings measured at one-minute intervals exceeds a threshold Δth=−40 beats, the second data processing unit 135 detects the heart rate data before and after the fluctuation as an abnormal value. When an abnormal value is detected, if the detected heart rate data is isolated from the heart rate data before and after it by exceeding the threshold Δth (second threshold), the second data processing unit 135 invalidates the heart rate data.

[0062] In the processing of the first data processing unit 130, the biological data may contain an error within the measurement range of the sensor 62 due to slight body movements of the bed occupant other than breathing and heartbeat. The second data processing unit 135 can discard the biological data containing the error within the measurement range. The biological information collecting device 100 can further improve the observation accuracy of the biological data at rest.
