Description

Technical Field

[0001] The present invention relates to a toilet system capable of providing health indicators of users. Background Art

[0002] Japanese Patent Application Laid-Open No. 2021-68396 (Patent Document 1) discloses a system that measures blood flow information of a toilet user sitting on a toilet seat, calculates and outputs health indicators based on the measurement results (for example, displays them on a display terminal).

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2021-68396 Summary of the Invention

[0004] As described above, a plurality of health indicators of a toilet user sitting on a toilet seat can be calculated (determined, diagnosed) based on the blood flow state of the user.

[0005] Specifically, a laser sensor that can measure the blood flow status in the skin on the back of the user's thigh based on the dynamic light scattering method is installed on the toilet seat, and the output signal of the laser sensor is subjected to Fourier transform, thereby calculating multiple health indicators such as pulse wave, blood flow, and heart rate.

[0006] Figure 6 This is an example of a laser sensor output signal. This signal is obtained by laser Doppler flowmetry and shows the oscillation of skin blood perfusion (peripheral blood flow).

[0007] Figure 7 It will Figure 6 The following is an example of a wavelet-transformed signal. Frequency region A (0.0095-0.021 Hz) shows neurogenic activity in the vascular endothelium, frequency region B (0.021-0.052 Hz) shows neurogenic activity in the vascular wall, frequency region C (0.052-0.145 Hz) shows neurogenic activity in vascular smooth muscle, frequency region D (0.145-0.6 Hz) shows respiratory activity, and frequency region E (0.6-2 Hz) shows cardiac activity.

[0008] Here, the blood flow measurement conditions required to calculate a health indicator with a certain degree of accuracy (reliability) vary for each health indicator. Specifically, there are health indicators that use the blood flow state after the user moves to the bathroom and sits on the toilet seat and stabilizes in a "resting state" as the appropriate measurement condition, or health indicators that use the blood flow state from the end of exercise to the state of rest before the user moves to the bathroom and sits on the toilet seat and stabilizes in a resting state as the appropriate measurement condition.

[0009] That is, if the health index is not calculated based on the blood flow state under appropriate measurement conditions, there is a possibility that a result that more accurately reflects the user's actual health index cannot be provided.

[0010] The present invention has been made based on the above findings and has an object to provide a toilet system that can provide evaluation results of a user's health index and can provide evaluation results that more accurately reflect the user's actual health index.

[0011] The present invention is a toilet system, characterized in that it comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures physical quantities reflecting blood flow information of the user; a health index evaluation unit that evaluates the health index of the user based on the measurement results of the sensor; and a health index output unit that outputs the health index of the user evaluated by the health index evaluation unit, wherein the health index evaluation unit evaluates the health index of the user based on the measurement results of the sensor for a time period that meets a specified stability judgment condition.

[0012] According to the present invention, by setting appropriate "stability judgment conditions" for the evaluation of stable reflection type health indicators (health indicators that are well reflected in the measurement signals in a stable state), it is possible to judge that the user sitting on the toilet seat has reached a stable state, and to provide an evaluation result that more accurately reflects the user's actual stable reflection type health indicators.

[0013] Preferably, the time period is a portion of a continuous sitting time of the user on the toilet seat.

[0014] By continuing to sit on the toilet seat, the user will stabilize in a "quiet state", so it is appropriate to effectively use a portion of such a period of time.

[0015] However, temporary (within a specified time) separation from the toilet seat due to the user's physical movement (e.g., resitting) may be permitted. In this case, the time period preferably excludes the time the user temporarily separated from the toilet seat, and includes the portion of the time period that combines the user's seated time before and after the separation time (i.e., the measurement data before and after the separation time are preferably combined).

[0016] Furthermore, for example, the stability determination condition is a condition related to the degree of fluctuation of the stability determination signal based on the sensor's measurement signal. This condition setting is effective because it is believed that the degree of fluctuation of the stability determination signal decreases when the user's "resting state" is high.

[0017] Specifically, the stability determination signal is, for example, a blood flow signal or a pulse wave signal. The inventors have verified that by using these signals as stability determination signals, an evaluation result that more accurately reflects a stability-reflecting health index can be provided.

[0018] Furthermore, in the present invention, the health index evaluation unit preferably evaluates the user's health index based on the sensor measurement results collected for a time period that satisfies the predetermined stability determination condition until a predetermined total time has been reached, wherein the predetermined stability determination condition is a condition based on a stability determination signal of the sensor's measurement signal temporarily becoming stable. In this case, measurement data for a continuous time period from the moment a stable state is temporarily reached (i.e., for example, after the user's pulse wave temporarily becomes stable) until the predetermined total time has been reached can be effectively used.

[0019] This allows the measurement data for the time period until the stability determination signal reaches a stable state to be excluded from the evaluation target, thereby providing an evaluation result that more accurately reflects the user's actual stability-reflecting health index.

[0020] Alternatively, in the present invention, the health index evaluation unit preferably evaluates the user's health index based on the sensor measurement results collected for a time period that satisfies the predetermined stability determination condition until a predetermined total time is reached, wherein the predetermined stability determination condition is a condition that a stability determination signal based on the sensor measurement signal maintains a stable state. In this case, the measurement data for the time period that maintains a stable state is collected (and combined if discontinuous) until the predetermined total time is reached, and is effectively used.

[0021] In this way, the measurement data of the time period from the initial entry of the stability determination signal into the stable state can be excluded from the evaluation object. On this basis, the measurement data of the time period in which the stability determination signal again leaves the stable state due to the "exertion" or other "body movements" of the user while using the toilet can also be excluded from the evaluation object. Therefore, an evaluation result that more accurately reflects the user's actual stability-reflecting health indicator can be provided.

[0022] Furthermore, it is preferable that the health index evaluation unit evaluates the health index of the user based on the measurement result of the sensor for a time period that further satisfies a second predetermined stability determination condition among the time periods that satisfy the predetermined stability determination condition.

[0023] This allows the second predetermined stability determination condition to selectively and effectively utilize a more advanced state of the user's "resting state," thereby providing an evaluation result of a stability-reflecting health index that more accurately reflects the user's actual state.

[0024] Alternatively, the present invention is a toilet system, characterized in that it comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures physical quantities reflecting blood flow information of the user; a health index evaluation unit that evaluates the health index of the user based on the measurement results of the sensor; and a health index output unit that outputs the health index of the user evaluated by the health index evaluation unit, the health index evaluation unit evaluating the health index of the user based on the measurement results of the sensor after the user has sat on the toilet seat for more than a specified time.

[0025] According to the present invention, by utilizing the fact that it can be inferred that the user has reached a "resting state" by sitting for more than a prescribed time, a "prescribed time" appropriate for the evaluation of stable-reflection health indicators (health indicators that are well reflected in the measurement signals in a stable state) is set, thereby providing an evaluation result that more accurately reflects the user's actual stable-reflection health indicators.

[0026] Alternatively, the present invention is a toilet system, characterized in that it comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures physical quantities reflecting blood flow information of the user; a health index evaluation unit that evaluates the health index of the user based on the measurement results of the sensor; and a health index output unit that outputs the health index of the user evaluated by the health index evaluation unit, the health index evaluation unit evaluating the health index of the user based on the measurement results of the sensor related to a time period after the user has sat on the toilet seat for more than a specified time and meets a specified stability judgment condition.

[0027] According to the present invention, by setting appropriate "specified time" and "stable judgment conditions" for the evaluation of stable reflection type health indicators (health indicators that are well reflected in the measurement signals in a stable state), it is possible to provide evaluation results that more accurately reflect the user's actual stable reflection type health indicators.

[0028] For example, instead of determining the initial stable state, determination that the seating time exceeds a predetermined time can be used, and then measurement data of the time period in which the stable state is maintained can be collected (joined if discontinuous) until the predetermined total time is reached for effective use.

[0029] In addition, in the present invention, the methods in the patent protection category are also the protection objects of this application.

[0030] That is, one embodiment of the present invention involves a method for providing an evaluation result of a health index using a toilet system, the toilet system comprising: a toilet seat having a seating surface for a user to sit on; a sensor for measuring a physical quantity reflecting blood flow information of the user; a health index evaluation unit for evaluating the health index of the user based on the measurement result of the sensor; and a health index output unit for outputting the health index of the user evaluated by the health index evaluation unit. The method is characterized in that it comprises the following step, namely, evaluating the health index of the user based on the measurement result of the sensor for a time period that satisfies a specified stability judgment condition.

[0031] In addition, in the present invention, the programs in the patent protection category are also the protection objects of this application.

[0032] That is, one embodiment of the present invention involves a program that provides evaluation results of health indicators using a toilet system, wherein the toilet system comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures physical quantities reflecting blood flow information of the user; a health indicator evaluation unit that evaluates the health indicator of the user based on the measurement results of the sensor; and a health indicator output unit that outputs the health indicator of the user evaluated by the health indicator evaluation unit. The program is characterized in that, by executing the program by a computer, the following process can be implemented, namely, evaluating the health indicator of the user based on the measurement results of the sensor for a time period that satisfies a specified stability judgment condition.

[0033] In addition, another embodiment of the present invention is a toilet system, characterized in that it comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures a physical quantity reflecting blood flow information of the user; a health index evaluation unit that evaluates the health index of the user based on the measurement result of the sensor; and a health index output unit that outputs the health index of the user evaluated by the health index evaluation unit, the health index evaluation unit evaluating the health index of the user based on the measurement result of the sensor related to a specified time obtained by going back from the time when the user finishes using the toilet seat and leaves the toilet seat.

[0034] According to the present invention, by utilizing measurement data at the end of toilet seat use (latter half) when the user is likely to be in a quiet state, it is possible to provide evaluation results of stable health indicators that more accurately reflect the user's actual condition.

[0035] In this case, the health index evaluation unit preferably evaluates the health index of the user based on the measurement results of the sensor related to the time period that meets the specified stability judgment conditions within the specified time obtained by going back from the time when the user finishes using the toilet seat and gets off the toilet seat.

[0036] Therefore, by utilizing the measurement data of the time period at the end of toilet seat use when the user is likely to be in a quiet state, and on this basis, setting appropriate "stability judgment conditions" for the evaluation of stable reflection-type health indicators (health indicators that are well reflected in the measurement signals in a stable state), the measurement data of the time period that does not meet the stability judgment conditions can be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual stable reflection-type health indicators.

[0037] Alternatively, in this case, the health index evaluation unit preferably evaluates the health index of the user based on the measurement results of the sensor collected for a time period starting from the time when the user finishes using the toilet seat and gets off the toilet seat and satisfies the prescribed stability judgment condition until a prescribed total time is reached, and the prescribed stability judgment condition is a condition that a stability judgment signal of the measurement signal of the sensor maintains a stable state.

[0038] Therefore, by utilizing the measurement data of the time period at the end of toilet seat use when the user is likely to be in a quiet state, and by excluding the measurement data of the time period that does not meet the stability judgment conditions from the evaluation object, and on this basis, using a sufficient amount of measurement data corresponding to the specified total time, it is possible to provide an evaluation result that more accurately reflects the user's actual stability-reflecting health indicators.

[0039] In addition, another embodiment of the present invention is a toilet system, characterized in that it comprises: a toilet seat having a seating surface for a user to sit on; a sensor that measures a physical quantity reflecting the blood flow information of the user; a health index evaluation unit that evaluates the health index of the user based on the measurement results of the sensor; and a health index output unit that outputs the health index of the user evaluated by the health index evaluation unit, the health index evaluation unit evaluating the health index of the user based on the measurement results of the sensor related to a specified time obtained by looking back from the end of the set measurement time of the sensor.

[0040] According to the present invention, by utilizing the measurement data of the end phase (second half) of the set measurement time of the sensor when the user is likely to be in a resting state, it is possible to provide an evaluation result that more accurately reflects the user's actual stable reflection type health indicator.

[0041] In this case, the health index evaluation unit preferably evaluates the health index of the user based on the measurement results of the sensor related to the time period that meets the specified stability judgment conditions within the specified time obtained by looking back from the end of the set measurement time of the sensor.

[0042] Therefore, by utilizing the measurement data of the time period at the end stage of the measurement time of the sensor in which the user is likely to be in a resting state, and on this basis, setting appropriate "stable judgment conditions" for the evaluation of stable reflection type health indicators (health indicators that are well reflected in the measurement signals in a stable state), the measurement data of the time period that does not meet the stable judgment conditions can be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual stable reflection type health indicators.

[0043] Alternatively, in this case, the health index evaluation unit preferably evaluates the health index of the user based on the measurement results of the sensor collected for a time period starting from the end of the set measurement time of the sensor and looking back in time to a specified total time that satisfies a specified stability judgment condition, and the specified stability judgment condition is a condition that a stability judgment signal of the measurement signal of the sensor maintains a stable state.

[0044] Therefore, since the measurement data of the time period at the end of the set measurement time of the sensor in which the user is likely to be in a resting state is utilized, and the measurement data of the time period that does not meet the stability judgment conditions can be excluded from the evaluation object, and on this basis, a sufficient amount of measurement data corresponding to the specified total time is used, it is possible to provide an evaluation result that more accurately reflects the user's actual stability-reflecting health indicators.

[0067] This embodiment targets the following health indicators, among various health indicators, by using measurement data of the blood flow state of a user who has moved to the bathroom and sat on the toilet seat, after stabilizing in a "resting state," thereby obtaining calculation results with higher accuracy (reliability). Specifically, these health indicators include "body water balance," "relaxation level," and "blood flow."

[0068] It can be considered that whether the user is stable in a "resting state" corresponds to whether the measurement signal of the sensor itself, as described later, or the stability judgment signal obtained by processing the measurement signal of the sensor (such as a blood flow signal or a pulse wave signal) meets the specified stability judgment conditions.

[0069] "Body water balance" is a state (indicator) related to the water content in the blood and / or the electrolyte concentration in the blood. These are respectively related to blood information signals related to breathing or heartbeat and their changes (the signal intensities and changes of multiple target frequency components). Therefore, based on these signal intensities and changes, the body's water balance (water and / or electrolyte concentrations in the blood) can be estimated and evaluated.

[0070] The “relaxation level” is related to the blood information signal and its changes (for example, in a state of relaxation without stress, the frequency components in the low-frequency region ( Figure 7 The frequency region A to E) increases, and when one is under pressure and cannot relax, the frequency components in the low-frequency region ( Figure 7 Therefore, the relaxation level can be estimated and evaluated based on the signal intensity and its changes.

[0071] "Blood flow" is related to health conditions such as "edema" or "coldness" in the lower limbs, physical and mental discomfort, and blood circulation disorders.

[0072] Moreover, the inventors have discovered that when evaluating this type of health indicator (which is referred to as a "stable-reflection health indicator" in this specification because it is a health indicator that is well reflected in the measurement signal in a stable state), the measurement signal of the sensor itself, or the measurement results of the time period in which the stable judgment signal obtained by processing the measurement signal of the sensor meets the specified stable judgment conditions, can be effectively used, thereby providing results that more accurately reflect the user's actual health indicators.

[0073] More specifically, the specified stability judgment condition may be a condition in which the measurement signal of the sensor itself, or a stability judgment signal obtained by processing the measurement signal of the sensor temporarily becomes a stable state (in this case, measurement data of a continuous time period from temporarily becoming a stable state to reaching a specified total time is effectively used).

[0074] Alternatively, the predetermined stability determination condition may be a condition that the measurement signal of the sensor itself, or a stability determination signal obtained by processing the measurement signal of the sensor, maintains a stable state. (In this case, the measurement data of the time period in which the stable state is maintained can be collected (or combined if discontinuous) until a predetermined total time is reached and effectively used.)

[0075] Alternatively, the prescribed stability determination condition may be a condition in which the user's seating time on the toilet seat exceeds a prescribed seating time, and the measurement signal of the sensor itself, or a stability determination signal obtained by processing the measurement signal of the sensor, maintains a stable state (in this case, for example, after using the determination of the prescribed seating time instead of the initial stable state, the measurement data of the time period in which the stable state is maintained can be collected (and joined if discontinuous) until the prescribed total time is reached, and effectively used).

[0076] (structure)

[0077] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a schematic perspective view of a toilet system 10 according to one embodiment of the present invention. Figure 2 yes Figure 1 An exploded oblique view of the toilet seat 20 of the toilet system 10, Figure 3 Yes Figure 1 A schematic block diagram of the main parts of the toilet system 10.

[0078] like Figures 1 to 3 As shown, the toilet system 10 of this embodiment includes a toilet seat 20, a main body 12, and a toilet lid 14. The toilet seat 20 and the toilet lid 14 are axially supported relative to the main body 12 so as to be rotatable.

[0079] The toilet seat 20 is equipped with a laser sensor 40 as a sensor that measures physical quantities reflecting the user's blood flow information, and an electrostatic sensor 50 as a seating sensor. Furthermore, the toilet seat 20 is equipped with a health index calculation unit 60 (specifically, a microprocessor, for example) that calculates the user's health index based on the measurement results of the laser sensor 40.

[0080] The toilet seat 20 has an opening 20a. In this embodiment, an O-shaped opening 20a is formed in the center of the toilet seat 20. The opening of the toilet seat 20 is not limited to an O-shape and may also be a U-shape, etc. The outer edge of the toilet seat 20 is formed by curving along the outer shape of the toilet bowl 4. The toilet seat 20 is generally formed of an opaque resin material (e.g., polypropylene) and has a seating surface 21 for the user to sit on and a bottom surface 25 opposite the seating surface 21.

[0081] The seating surface 21 is the surface that faces upward when the toilet seat 20 is placed on the upper surface 4b of the toilet bowl 4 and is the surface on which the user sits. The bottom surface 25 is the surface that faces the upper surface 4b of the toilet bowl 4 when the toilet seat 20 is lowered. The toilet seat 20 is composed of a thick-walled portion 22 that is formed generally thick throughout. A thin-walled portion 23 that is thinner than the thick-walled portion 22 is partially formed at a position corresponding to the laser sensor 40.

[0082] like Figure 2 As shown, a heating wire 30 (an example of a heater) and a heat insulating material 32 are provided inside the toilet seat 20 to heat and maintain the seat surface 21. The heating wire 30 is controlled by a toilet seat heating unit 12b provided within the main body 12 and extends throughout the interior of the toilet seat 20 so as not to interfere with the laser sensor 40, the electrostatic sensor 50, and the health index calculation unit 60. The heat insulating material 32 is positioned below the heating wire 30, the laser sensor 40, the electrostatic sensor 50, and the health index calculation unit 60.

[0083] Thin-walled portion 23 is thick enough to transmit light emitted from laser sensor 40 and light reflected from a user sitting on seat surface 21. The thickness of thin-walled portion 23 is set based on the intensity of the light emitted and reflected from laser sensor 40, the durability of toilet seat 20, and other factors, and is, for example, approximately 0.5 mm to 1.0 mm.

[0084] In this specification, “above,” “below,” “front,” “rear,” “left,” and “right” respectively refer to directions viewed from the back by a user sitting on the toilet seat 20 with the toilet lid 14 opened.

[0085] like Figure 2 As shown, the thin-walled portion 23 is formed on the front left side relative to the center of the length of the opening 20a of the toilet seat 20 in the front-to-back direction, and is located on the front left side relative to the center of gravity of a user sitting on the toilet seat 20. Thus, the thin-walled portion 23 faces (contacts) the back side of the left thigh of a user sitting on the toilet seat 20.

[0086] The thin portion 23 is formed as small as possible within a range where the laser sensor 40 can detect blood flow information of a user sitting on the toilet seat 20 , for example, into a circle with a diameter of 12 mm or less (preferably 8 mm or less).

[0087] Laser sensor 40 is located inside toilet seat 20, on the back side of thin-walled portion 23. Laser sensor 40 is a reflective sensor that irradiates infrared light toward the back side of the user's left thigh and detects reflected light (scattered light that has undergone a Doppler shift due to red blood cells) that reflects light according to the blood flow in blood vessels beneath the skin. Figure 4 It is a diagram schematically showing the structure of the laser sensor 40 .

[0088] On the other hand, Figure 1 and Figure 2 As shown, the electrostatic sensor 50 is formed on the front right side relative to the center of the length of the opening 20a of the toilet seat 20 in the front-to-back direction, and is located on the front right side relative to the center of gravity of a user sitting on the toilet seat 20. Thus, the electrostatic sensor 50, as an example of a seating sensor, can detect a sitting state when it faces (contacts) the back side of the right thigh of a user sitting on the toilet seat 20.

[0089] In this embodiment, the health index calculation unit 60 is located near the front end of the toilet seat 20 (relatively close to the laser sensor 40) and processes the output signal of the laser sensor 40 to convert it into a signal that is relatively resistant to noise. Specifically, the health index calculation unit 60 calculates the health index of the user sitting on the toilet seat 20 (specifically, pulse rate, pulse variability, blood flow, etc.) based on the measurement results of the laser sensor 40, and transmits a signal corresponding to the calculation result to the communication unit 75 via the control unit 70. Figure 5 is a schematic diagram showing the calculation process of various health indicators based on the measurement results of the laser sensor 40. Figure 6 is an example of a graph showing a measurement signal of the laser sensor 40. Figure 7 This is an example of a graph obtained by performing wavelet transformation on the measurement signal of the laser sensor 40 .

[0090] The control unit 70 and the communication unit 75 are disposed within the main body 12. The health index calculation unit 60 may be disposed within the main body 12 instead of within the toilet seat 20. When the health index calculation unit 60 is disposed within the main body 12, it may be disposed separately from the control unit 70 or may be integrally disposed as part of the control unit 70.

[0091] Furthermore, the health index calculation unit 60 and the control unit 70 may not be located in the main body 12 but may be provided (built) in an external device or an external network (eg, a cloud) that communicates via the communication unit 75 .

[0092] return Figure 1 The main body 12 is located behind the toilet bowl 4 and is attached to the upper surface 4b of the toilet bowl 4. The main body 12 houses an opening and closing unit 12a that controls the opening and closing of the toilet seat 20 and lid 14; a toilet seat heating unit 12b that controls the temperature of the toilet seat 20; a cleaning unit 12c that cleans the body's surroundings; and a deodorizing unit 12d that reduces odors. Each unit 12a-12d is centrally controlled by a control unit 70. The control unit 70 of this embodiment is also connected to the electrostatic sensor 50.

[0093] Furthermore, the control unit 70 of this embodiment is connected to a communication unit 75 (an example of a health index output unit) for outputting the user's health index calculated by the health index calculation unit 60. The communication unit 75 transmits the calculated user health index to, for example, a toilet remote control 80 or a user's portable terminal 85. Furthermore, a user sitting on the toilet seat 20 can check various health indicators (vital signs such as pulse rate) via the display unit 80a of the remote control 80 or the display unit 85a of the portable terminal 85.

[0094] Furthermore, the control unit 70 of the present embodiment functions as a seating determination unit and determines whether or not the user is seated on the seating surface 21 based on the measurement result of the electrostatic sensor 50 .

[0095] In addition, the control unit 70 of this embodiment functions as a signal stability determination unit to determine the pulse wave signal (an example of a stability determination signal, see Figure 8 ) whether it temporarily becomes a stable state (i.e., whether the user's pulse wave temporarily becomes a stable state).

[0096] Specifically, for a period of time equivalent to one cycle from a certain minimum value to a maximum value and then to the next minimum value of the pulse wave signal, if its variation is within ±10% (the first variation range), the control unit 70 of this embodiment determines that it has temporarily reached a stable state.

[0097] Here, the fluctuation in the time equivalent to one cycle of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value from the time the person sits down on the seating surface until the stable state is reached decreases. Specifically, the first fluctuation range (within ±10%) of the time equivalent to one cycle of the pulse wave signal in the stable state is smaller than the time equivalent to one cycle of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value from the time the person sits down until the stable state is reached. In other words, the first fluctuation range (within ±100%) of the time equivalent to one cycle of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value from the time the person sits down until the stable state is reached is smaller than the second fluctuation range (within ±100%) of the time equivalent to one cycle of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value (corresponding to the stable fluctuation state). Therefore, it can be said that the control unit 70 determines that the stable state has been reached if the fluctuation in the time equivalent to one cycle of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value falls within the first fluctuation range, which is smaller than the second fluctuation range.

[0098] Furthermore, after determining that the pulse wave signal has temporarily reached a stable state, the control unit 70 of the present embodiment functions as a signal stability maintenance determination unit to determine whether the pulse wave signal maintains such a stable state.

[0099] Specifically, if the pulse wave signal fluctuates by more than ±10% again during a period corresponding to one cycle from a certain minimum value to a maximum value and then to the next minimum value, the control unit 70 of this embodiment determines that the maintenance of the stable state is interrupted.

[0100] The toilet system 10 of this embodiment includes a timer 95 that works in conjunction with the control unit 70 to measure the time (or, if discontinuous, the duration of each time period) during which the pulse wave signal maintains a stable state.

[0101] The amount of the output signal of the laser sensor 40 required to calculate a health index with a certain degree of accuracy (reliability), that is, the measurement time taken by the laser sensor 40 , differs for each health index.

[0102] The toilet system 10 of this embodiment is based on the following design concept, that is, for each "stable reflection type health indicator" for which process monitoring (surveillance) is desired, for example, when a stable output waveform signal equivalent to a measurement time of 20 seconds (or more) is obtained, a calculated value with a certain degree of accuracy (reliability) can be obtained.

[0103] That is, the control unit 70 of this embodiment determines whether the duration (the cumulative time when there is an interruption time in the middle) during which the pulse wave signal maintains a stable state is, for example, more than 30 seconds (an example of a "prescribed total time": a time between 30 seconds and 120 seconds, preferably a time between 30 seconds and 60 seconds, and more preferably 45 seconds) based on the measurement results of the electrostatic sensor 50 and the measurement results of the timer 95.

[0104] Furthermore, the control unit 70 of this embodiment determines (determines processing 1) the measurement results (measurement data) of the laser sensor 40 related to a specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the time when the user finishes using the toilet seat and leaves the toilet seat based on the measurement results of the electrostatic sensor 50 and the measurement results of the timer 95.

[0105] Alternatively, the control unit 70 of this embodiment determines the measurement results (measurement data) of the laser sensor 40 related to the time during which the pulse wave signal maintains a stable state within a specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the time when the user finishes using the toilet seat and gets off the toilet seat (determination processing 2).

[0106] Alternatively, the control unit 70 of this embodiment determines the measurement result (measurement data) of the laser sensor 40 related to the specified total time (the cumulative time, for example, 20 seconds if there is an interruption time in the middle) during which the pulse wave signal maintains a stable state within a specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the time when the user finishes using the toilet seat and gets off the toilet seat (determination processing 3).

[0107] In addition, the control unit 70 of this embodiment determines (determines processing 4) the measurement results (measurement data) of the laser sensor 40 related to the specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the end of the set measurement time (for example, 90 seconds) of the laser sensor 40 based on the measurement results of the electrostatic sensor 50 and the measurement results of the timer 95.

[0108] Alternatively, the control unit 70 of this embodiment determines the measurement results (measurement data) of the laser sensor 40 related to the time during which the pulse wave signal maintains a stable state within a specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the end of the set measurement time of the laser sensor 40 (for example, 90 seconds) based on the measurement results of the electrostatic sensor 50 and the measurement results of the timer 95 (determination processing 5).

[0109] Alternatively, the control unit 70 of this embodiment determines (determines processing 6) the measurement results (measurement data) of the laser sensor 40 related to the specified total time (the cumulative time, for example, 20 seconds if there is an interruption time in the middle) during which the pulse wave signal maintains a stable state within a specified time (an example of a "specified time": a time between 10 seconds and 90 seconds, preferably a time between 10 seconds and 60 seconds, and more preferably 30 seconds) obtained by looking back from the end of the set measurement time of the laser sensor 40 (for example, 90 seconds) based on the measurement results of the electrostatic sensor 50 and the measurement results of the timer 95.

[0110] Furthermore, the timer 95 of this embodiment can be linked to the electrostatic sensor 50 to measure the duration of the unseated state when the person sits down once and then leaves the seat.

[0111] Furthermore, in the first operation example described later, the control unit 70 controls the

[0112] (0) If the user leaves his seat before the user's pulse wave signal reaches a stable state, the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index".

[0113] (1) After the user's pulse wave signal temporarily reaches a stable state, if the pulse wave signal maintains the stable state for a duration of, for example, 30 seconds (an example of the "predetermined total time") or longer, the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0114] (2) After the user's pulse wave signal temporarily reaches a stable state, if the user leaves his seat before the pulse wave signal maintains the stable state for a duration of, for example, 30 seconds (an example of the "prescribed total time"), the communication unit 75 (health indicator output unit) stops outputting the "stable reflection type health indicator".

[0115] Furthermore, in a second operation example described later, the control unit 70, based on the above-mentioned determination result,

[0116] (3) After the pulse wave signal of the user temporarily reaches a stable state, if the user temporarily (for example, less than 15 seconds) leaves the seat and sits down again before the pulse wave signal maintains the stable state for, for example, 30 seconds (an example of the "prescribed total time"), the measurement data of the time period during which the user temporarily left the seat are excluded. If the cumulative sitting time since the pulse wave signal became stable exceeds, for example, 30 seconds (an example of the "prescribed total time"), the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0117] Furthermore, in a third operation example described later, the control unit 70, based on the above-mentioned determination result,

[0118] (4) After the pulse wave signal of the user temporarily reaches a stable state, if the pulse wave signal temporarily becomes unstable before the duration of the pulse wave signal maintaining the stable state reaches, for example, 30 seconds (an example of the "prescribed total time"), the measurement data of the time period during which the pulse wave signal temporarily becomes unstable are excluded. If the cumulative time for the pulse wave signal to become stable exceeds, for example, 30 seconds (an example of the "prescribed total time"), the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0119] Furthermore, for the fourth to sixth action examples described later, the control unit 70 of this embodiment acts as a signal stability estimation unit, and determines, based on the measurement results of the timer 95, whether a stable estimation time (for example, set to 45 seconds after the person is seated) has passed, during which the pulse wave signal is estimated to have temporarily become stable.

[0120] Furthermore, in the fourth operation example described later, the control unit 70 controls the

[0121] (0') When it is determined that the user has left the seat before the stable estimated time has passed after the user sat down, the communication unit 75 (health index output unit) stops outputting the "stability-reflecting health index",

[0122] (1') When it is determined that the user has sat down and the estimated stable time has passed, and the pulse wave signal has maintained a stable state for a duration of, for example, 30 seconds (an example of the "predetermined total time") or longer, the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0123] (2') When it is determined that the user has sat down and the stable estimated time has passed, if the pulse wave signal maintains a stable state for a duration of, for example, 30 seconds (an example of the "prescribed total time") before the user leaves the seat, the communication unit 75 (health indicator output unit) stops outputting the "stable reflection type health indicator".

[0124] Furthermore, in a fifth operation example described later, the control unit 70 performs the following operation based on the above-mentioned determination result:

[0125] (3') After the pulse wave signal of the user temporarily reaches a stable state, if the user temporarily leaves his seat (for example, for less than 15 seconds) and sits down again before the pulse wave signal maintains the stable state for, for example, 30 seconds (an example of the "prescribed total time"), the measurement data of the time period during which he temporarily left his seat are excluded. If the cumulative sitting time since the pulse wave signal became stable exceeds, for example, 30 seconds (an example of the "prescribed total time"), the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0126] Furthermore, in a sixth operation example described later, the control unit 70 performs the following operation based on the above-mentioned determination result:

[0127] (4') When it is determined that the user has sat down and the estimated stable time has passed, if the pulse wave signal becomes temporarily unstable before the duration for which the pulse wave signal maintains a stable state reaches, for example, 30 seconds (an example of the "prescribed total time"), the measurement data for the time period during which the pulse wave signal becomes temporarily unstable are excluded. When the cumulative time for which the pulse wave signal becomes stable exceeds, for example, 30 seconds (an example of the "prescribed total time"), the communication unit 75 (health index output unit) outputs a "stability-reflecting health index" calculated based on the measurement data for the 30 seconds.

[0128] Alternatively, in a seventh operation example described later, the control unit 70 performs the following operation based on the discrimination result and the determination processing 1:

[0129] (10) If the user leaves the seat before the user's sitting time reaches the specified time (e.g., 30 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index";

[0130] (11) When it is detected that a user has left his seat after the user's sitting time exceeds the prescribed time (for example, 30 seconds), the measurement results (measurement data) of the laser sensor 40 related to the prescribed time (for example, 30 seconds) obtained by looking back from the user's leaving the seat are determined, and a "stable reflection type health index" calculated based on the measurement data of each prescribed time amount is output.

[0131] Alternatively, in an eighth operation example described later, the control unit 70 performs the following operation based on the determination result and the determination process 2.

[0132] (10) If the user leaves the seat before the user's sitting time reaches the specified time (e.g., 30 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index";

[0133] (11') When it is detected that a user has left his seat after the user has been seated for a period exceeding the prescribed time (e.g., 30 seconds), the measurement result (measurement data) of the laser sensor 40 related to the time during which the pulse wave signal maintains a stable state within the prescribed time (e.g., 30 seconds) obtained by looking back from the user leaving the seat is determined, and a "stable reflection type health index" calculated based on the measurement data of the prescribed time is output.

[0134] Alternatively, in a ninth operation example described later, the control unit 70 performs the following operation based on the determination result and the determination process 3.

[0135] (10) If the user leaves the seat before the user's sitting time reaches the specified time (e.g., 30 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index";

[0136] (11") When it is detected that a user has left his seat after the user has been seated for a period exceeding the prescribed time (e.g., 30 seconds), the measurement result (measurement data) of the laser sensor 40 related to the prescribed total time (in the case of an interruption time in the middle, the cumulative time, e.g., 20 seconds) during which the pulse wave signal maintains a stable state within the prescribed time (e.g., 30 seconds) obtained by looking back from the user's leaving the seat is determined, and a "stability-reflecting health index" calculated based on the measurement data of each prescribed time amount is output.

[0137] Alternatively, in a tenth operation example described later, the control unit 70 performs the following operation based on the determination result and the determination processing 4.

[0138] (20) If the user leaves the seat before the user's sitting time reaches the set measurement time (e.g., 90 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index."

[0139] (21) When the user's sitting time exceeds the set measurement time (for example, 90 seconds), the measurement results (measurement data) of the laser sensor 40 related to the specified time (for example, 30 seconds) obtained by looking back from the end of the set measurement time are determined, and a "stable reflection type health index" calculated based on the measurement data of each specified time amount is output.

[0140] Alternatively, in an eleventh operation example described later, the control unit 70 performs the following operation based on the determination result and the determination process 5.

[0141] (20) If the user leaves the seat before the user's sitting time reaches the set measurement time (e.g., 90 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index."

[0142] (21') When the user's sitting time exceeds the set measurement time (for example, 90 seconds), the measurement result (measurement data) of the laser sensor 40 related to the time during which the pulse wave signal maintains a stable state within the specified time (for example, 30 seconds) obtained by looking back from the end of the set measurement time is determined, and a "stable reflection type health index" calculated based on the measurement data of each specified time amount is output.

[0143] Alternatively, in a twelfth operation example described later, the control unit 70 performs the following operation based on the determination result and the determination process 6.

[0144] (20) If the user leaves the seat before the user's sitting time reaches the set measurement time (e.g., 90 seconds), the communication unit 75 (health index output unit) stops outputting the "stable reflection type health index."

[0145] (21”) When the user’s sitting time exceeds the set measurement time (e.g., 90 seconds), the measurement result (measurement data) of the laser sensor 40 related to the prescribed total time (in the case of an interruption time in the middle, it is the cumulative time, e.g., 20 seconds) during which the pulse wave signal maintains a stable state within the prescribed time (e.g., 30 seconds) obtained by looking back from the end of the set measurement time is determined, and a “stable reflection type health index” calculated based on the measurement data of each prescribed time amount is output.

[0146] In this embodiment, the calculated and output user's "stable-reflective health index" is transmitted to the bathroom remote control 80 or the user's portable terminal 85. Thus, the user sitting on the toilet seat 20 can check the "stable-reflective health index" on the display unit 80a of the remote control 80 or the display unit 85a of the portable terminal 85.

[0147] Here, in this embodiment, the comparison result between the "stability-reflecting health index" newly evaluated by the health index calculation unit 60 (an example of a health index evaluation unit) and the "stability-reflecting health index" evaluated in the past can be output.

[0148] Furthermore, in this embodiment, the comparison result between the "stable-reflective health index" most recently evaluated by the health index calculation unit 60 (an example of a health index evaluation unit) and a predetermined threshold value can be output. Specifically, the "stable-reflective health index" can be evaluated as a score value between 0 and 100.

[0149] (Action Example 1: Function)

[0150] Regarding the toilet system 10 of this embodiment, use Figure 9 The first operation example is described. Figure 9 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0151] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to identify the pulse wave signal (see Figure 8 ) temporarily becomes a stable state (STEP 12). In order to assist in this determination, the health index calculation unit 60 generates (calculates) the user's pulse wave signal based on the measurement results of the laser sensor 40.

[0152] Before the user's pulse wave signal reaches a stable state (STEP12 is NO), the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), and the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health index output unit) to stop outputting the evaluation results of the "stable reflection type health index" (STEP03).

[0153] Before the user's pulse wave signal reaches a stable state (NO in STEP 12 ), the electrostatic sensor 50 does not detect that the user has left the seat (NO in STEP 01 ), and the process waits for the user's pulse wave signal to reach a stable state (return to STEP 12 ).

[0154] Even if the electrostatic sensor 50 detects that the user has left their seat (STEP 01 is YES), if the user is detected to be sitting down again (STEP 02 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the user's pulse wave signal will be waited for to reach a stable state (return to STEP 12).

[0155] After the user's pulse wave signal temporarily reaches a stable state (STEP 12: YES), timer 95 begins measuring elapsed time (STEP 13). Then, when, for example, 30 seconds (required time: the "predetermined total time" in the first operation example) have elapsed (STEP 14: YES), communication unit 75 (health index output unit) outputs the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for this 30 seconds (STEP 15).

[0156] When the electrostatic sensor 50 detects that the user has left his seat before 30 seconds (the required time) after the pulse wave signal temporarily reaches a stable state (STEP 14 is NO), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds (however, it may also be a value different from the specified time for re-sitting determination in STEP 02)) (STEP 22 is YES), the control unit 70 causes the communication unit 75 (health index output unit) to stop outputting the evaluation result of the "stable reflection type health index" (STEP 23).

[0157] After the pulse wave signal temporarily reaches a stable state and before 30 seconds (required time) have passed (STEP14 is NO), and the electrostatic sensor 50 does not detect that the user has left the seat (STEP21 is NO), wait for 30 seconds (required time) to pass (return to STEP14).

[0158] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES), if the user is seated again (STEP22 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for 30 seconds (required time) (returns to STEP14).

[0159] (Action Example 1: Effect)

[0160] According to the first action example shown above, since the measurement data of the time period until the pulse wave signal (an example of a signal for stability judgment) becomes stable can be excluded from the evaluation object, reliable data can be obtained from normal actions performed in the toilet, such as sitting down, and evaluation results that more accurately reflect the user's actual health indicators can be provided.

[0161] (Action Example 2: Function)

[0162] Regarding the toilet system 10 of this embodiment, use Figure 10 The second operation example is described. Figure 10The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0163] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to identify the pulse wave signal (see Figure 8 ) temporarily becomes a stable state (STEP 12). In order to assist in this determination, the health index calculation unit 60 generates (calculates) the user's pulse wave signal based on the measurement results of the laser sensor 40.

[0164] Before the user's pulse wave signal reaches a stable state (STEP12 is NO), the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), and the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health index output unit) to stop outputting the evaluation results of the "stable reflection type health index" (STEP03).

[0165] Before the user's pulse wave signal reaches a stable state (STEP 12 is NO) and the electrostatic sensor 50 does not detect that the user has left the seat (STEP 01 is NO), wait for the user's pulse wave signal to reach a stable state (return to STEP 12).

[0166] Even if the electrostatic sensor 50 detects that the user has left their seat (STEP 01 is YES), if the user is detected to be sitting down again (STEP 02 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the user's pulse wave signal will be waited for to reach a stable state (return to STEP 12).

[0167] After the user's pulse wave signal temporarily reaches a stable state (STEP 12: YES), timer 95 begins measuring elapsed time (STEP 13). When a required time of, for example, 30 seconds ("predetermined total time" - "accumulated time" as described later) has initially elapsed (STEP 14: YES), communication unit 75 (health index output unit) outputs the evaluation result of the "stability-reflecting health index" calculated based on the 30 seconds of measurement data (STEP 15).

[0168] When the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES) before the required time (initially, for example, 30 seconds) has passed after the pulse wave signal temporarily reaches a stable state (STEP 14 is NO), the timer 95 stops measuring the elapsed time (STEP 24), and the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) is added to the "accumulated time" (initially 0 seconds) (STEP 25).

[0169] On the other hand, the duration of the seat-out state is measured. If the duration of the seat-out state exceeds the specified time for re-sitting determination (for example, less than 15 seconds (however, it can also be a value different from the specified time for re-sitting determination in STEP02)) (STEP22 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP23).

[0170] After the pulse wave signal temporarily reaches a stable state and before the required time (initially, for example, 30 seconds) has passed (STEP14 is NO), and the electrostatic sensor 50 does not detect that the user has left the seat (STEP21 is NO), wait for the required time (initially, for example, 30 seconds) to pass (return to STEP14).

[0171] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP 21 is YES), if the user is detected to be sitting down again (STEP 22 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the accumulated time calculated (updated) by STEP 25 is subtracted from the time required so far (for example, initially 30 seconds) to obtain a new required time (STEP 26), and on this basis, the elapsed time is measured again by the timer 95 (return to STEP 13).

[0172] (Action Example 2: Effect)

[0173] According to the second action example shown above, the measurement data of the time period until the pulse wave signal (an example of a signal for stability judgment) initially becomes stable can be excluded from the evaluation object. On this basis, the measurement data of the time period such as when the user temporarily leaves the seat due to the "body movement" of the user while using the toilet can also be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual health indicators.

[0174] (Action Example 3: Function)

[0175] Regarding the toilet system 10 of this embodiment, use Figure 11 The third operation example is described. Figure 11The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0176] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to identify the pulse wave signal (see Figure 8 ) temporarily becomes a stable state (STEP 12). In order to assist in this determination, the health index calculation unit 60 generates (calculates) the user's pulse wave signal based on the measurement results of the laser sensor 40.

[0177] Before the user's pulse wave signal reaches a stable state (STEP12 is NO), the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), and the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health index output unit) to stop outputting the evaluation results of the "stable reflection type health index" (STEP03).

[0178] Before the user's pulse wave signal reaches a stable state (NO in STEP 12 ), the electrostatic sensor 50 does not detect that the user has left the seat (NO in STEP 01 ), and the process waits for the user's pulse wave signal to reach a stable state (return to STEP 12 ).

[0179] Even if the electrostatic sensor 50 detects that the user has left their seat (STEP 01 is YES), if the user is detected to be sitting down again (STEP 02 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the user's pulse wave signal will be waited for to reach a stable state (return to STEP 12).

[0180] After the user's pulse wave signal temporarily reaches a stable state (STEP 12: YES), timer 95 begins measuring elapsed time (STEP 13). When a required time of, for example, 30 seconds ("predetermined total time" - "accumulated time" as described later) has initially elapsed (STEP 14: YES), communication unit 75 (health index output unit) outputs the evaluation result of the "stability-reflecting health index" calculated based on the 30 seconds of measurement data (STEP 15).

[0181] When the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES) before the required time (initially, for example, 30 seconds) has passed after the pulse wave signal temporarily reaches a stable state (STEP 14 is NO), the timer 95 stops measuring the elapsed time (STEP 24), and the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) is added to the "accumulated time" (initially 0 seconds) (STEP 25).

[0182] On the other hand, the duration of the seat-out state is measured. If the duration of the seat-out state exceeds the specified time for re-sitting determination (for example, less than 15 seconds (however, it can also be a value different from the specified time for re-sitting determination in STEP02)) (STEP22 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP23).

[0183] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP 21 is YES), if the user is detected to be sitting down again (STEP 22 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the accumulated time calculated (updated) by STEP 25 is subtracted from the time required so far (for example, initially 30 seconds) to obtain a new required time (STEP 26), and on this basis, the elapsed time is measured again by the timer 95 (return to STEP 13).

[0184] After the pulse wave signal temporarily reaches a stable state, before the required time (for example, initially 30 seconds) has passed (STEP14 is NO), the electrostatic sensor 50 does not detect that the user has left the seat (STEP21 is NO), and the pulse wave signal maintains a stable state (STEP31 is NO), wait for the required time (for example, initially 30 seconds) to pass (return to STEP14).

[0185] If the pulse wave signal temporarily becomes unstable (STEP31 is YES) before the required time (initially, for example, 30 seconds) has passed after the pulse wave signal temporarily reaches a stable state (STEP14 is NO), and the electrostatic sensor 50 does not detect that the user has left the seat (STEP21 is NO), then the timer 95 stops measuring the elapsed time (STEP32), and the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) is added to the "accumulated time" (initially 0 seconds) (STEP33). The accumulated time calculated (updated) in STEP33 is subtracted from the required time so far (initially, for example, 30 seconds) to obtain a new required time (STEP34), and the user waits for the pulse wave signal to reach a stable state again (return to STEP12).

[0186] (Action Example 3: Effect)

[0187] According to the third action example shown above, the measurement data of the time period from the initial entry of the pulse wave signal (an example of a signal for determining stability) into a stable state can be excluded from the evaluation object. On this basis, the measurement data of the time period in which the pulse wave signal (an example of a signal for determining stability) deviates from a stable state due to, for example, "exertion" or other "body movements" of the user while using the toilet can also be excluded from the evaluation object. Therefore, an evaluation result that more accurately reflects the user's actual health indicators can be provided.

[0188] (Action Example 4: Function)

[0189] Regarding the toilet system 10 of this embodiment, use Figure 12 The fourth operation example is described. Figure 12 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0190] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to process the pulse wave signal (see Figure 8 ) is estimated to determine whether the pulse wave signal has temporarily stabilized (STEPs 41 to 43). That is, the timer 95 starts measuring the elapsed time (STEP 41) to determine whether a stable estimated time (e.g., set to 45 seconds after the patient takes a seat) has elapsed, during which the pulse wave signal is estimated to have temporarily stabilized.

[0191] Before the stable estimation time has passed (STEP42 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0192] Before the stable estimated time has elapsed (NO in STEP 42 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the stable estimated time to elapse (returns to STEP 42 ).

[0193] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the stable estimation time to pass (return to STEP42).

[0194] After the estimated stability time has elapsed (YES in STEP 42), timer 95 is temporarily stopped (STEP 43), and elapsed time measurement by timer 95 is restarted (STEP 13). Furthermore, when the required time of, for example, 30 seconds ("predetermined total time" - "accumulated time" as described later) has initially elapsed (YES in STEP 14), communication unit 75 (health index output unit) is caused to output the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for this 30 seconds (STEP 15).

[0195] If the electrostatic sensor 50 detects that the user has left his seat before 30 seconds (the required time) has passed after the stable estimated time (STEP14 is NO) (STEP21 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds (however, it can also be a value different from the specified time for re-sitting determination in STEP02)) (STEP22 is YES), the control unit 70 causes the communication unit 75 (health index output unit) to stop outputting the evaluation results of the "stable reflection type health index" (STEP23).

[0196] After the stable estimated time has elapsed and before 30 seconds (required time) have passed (NO in STEP 14), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 21), and the process waits for 30 seconds (required time) to pass (return to STEP 14).

[0197] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES), if the user is seated again (STEP22 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for 30 seconds (required time) (returns to STEP14).

[0198] (Action Example 4: Effect)

[0199] According to the fourth action example shown above, measurement data of the time period until the pulse wave signal (an example of a signal for determining stability) becomes stable can be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual health index.

[0200] Furthermore, according to the fourth operation example described above, the determination of the passage of a predetermined sitting time is used instead of the determination of the pulse wave signal first entering a stable state. This simplifies the signal state determination process flow (procedure).

[0201] (Example 5: Function)

[0202] Regarding the toilet system 10 of this embodiment, use Figure 13 The fifth operation example is described. Figure 13 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0203] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to process the pulse wave signal (see Figure 8 ) is estimated to determine whether the pulse wave signal has temporarily stabilized (STEPs 41 to 43). That is, the timer 95 begins measuring elapsed time (STEP 41) to determine whether a stable estimated time (e.g., set to 45 seconds after the patient takes a seat) has passed, during which the pulse wave signal is estimated to have temporarily stabilized.

[0204] Before the stable estimation time has passed (STEP42 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0205] Before the stable estimated time has elapsed (NO in STEP 42 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the stable estimated time to elapse (returns to STEP 42 ).

[0206] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the stable estimation time to pass (return to STEP42).

[0207] After the estimated stability time has elapsed (YES in STEP 42), timer 95 is temporarily stopped (STEP 43), and elapsed time measurement by timer 95 is restarted (STEP 13). Furthermore, when the required time of, for example, 30 seconds ("predetermined total time" - "accumulated time" as described later) has initially elapsed (YES in STEP 14), communication unit 75 (health index output unit) is caused to output the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for this 30 seconds (STEP 15).

[0208] If the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES) before the required time (initially, for example, 30 seconds) has passed after the estimated stabilization time (STEP14 is NO), the timer 95 stops measuring the elapsed time (STEP24), and the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) is added to the "accumulated time" (initially 0 seconds) (STEP25).

[0209] On the other hand, the duration of the seat-out state is measured. If the duration of the seat-out state exceeds the specified time for re-sitting determination (for example, less than 15 seconds (however, it can also be a value different from the specified time for re-sitting determination in STEP02)) (STEP22 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP23).

[0210] After the stable estimated time has passed and before the required time (for example, initially 30 seconds) has passed (STEP 14 is NO), the electrostatic sensor 50 does not detect that the user has left the seat (STEP 21 is NO), and the required time (for example, initially 30 seconds) has passed (return to STEP 14).

[0211] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP 21 is YES), if the user is detected to be sitting down again (STEP 22 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the accumulated time calculated (updated) by STEP 25 is subtracted from the time required so far (for example, initially 30 seconds) to obtain a new required time (STEP 26), and on this basis, the elapsed time is measured again by the timer 95 (return to STEP 13).

[0212] (5th action example: effect)

[0213] According to the fifth action example shown above, it is also possible to exclude from the evaluation object the measurement data of the time period until the pulse wave signal (an example of a signal for stability judgment) initially becomes stable. On this basis, it is also possible to exclude from the evaluation object the measurement data of the time period such as when the user temporarily leaves the seat due to "body movement" of the user while using the toilet. Therefore, it is possible to provide an evaluation result that more accurately reflects the user's actual health indicators.

[0214] Furthermore, according to the fourth operation example described above, the determination of the passage of a predetermined sitting time is used instead of the determination of the pulse wave signal first entering a stable state. This simplifies the signal state determination process flow (procedure).

[0215] (Action Example 6: Function)

[0216] Regarding the toilet system 10 of this embodiment, use Figure 14 The sixth operation example is described. Figure 14 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0217] If it is determined that the user is sitting on the seating surface 21 (YES in STEP 11), the control unit 70 starts to process the pulse wave signal (see Figure 8 ) is estimated to determine whether the pulse wave signal has temporarily stabilized (STEPs 41 to 43). That is, the timer 95 starts measuring the elapsed time (STEP 41) to determine whether a stable estimated time (e.g., set to 45 seconds after the patient takes a seat) has elapsed, during which the pulse wave signal is estimated to have temporarily stabilized.

[0218] Before the stable estimation time has passed (STEP42 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0219] Before the stable estimated time has elapsed (NO in STEP 42 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the stable estimated time to elapse (returns to STEP 42 ).

[0220] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the stable estimation time to pass (return to STEP42).

[0221] After the estimated stability time has elapsed (YES in STEP 42), timer 95 is temporarily stopped (STEP 43), and elapsed time measurement by timer 95 is restarted (STEP 13). Furthermore, when the required time of, for example, 30 seconds ("predetermined total time" - "accumulated time" as described later) has initially elapsed (YES in STEP 14), communication unit 75 (health index output unit) is caused to output the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for this 30 seconds (STEP 15).

[0222] If the electrostatic sensor 50 detects that the user has left the seat (STEP21 is YES) before the required time (initially, for example, 30 seconds) has passed after the estimated stabilization time (STEP14 is NO), the timer 95 stops measuring the elapsed time (STEP24), and the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) is added to the "accumulated time" (initially 0 seconds) (STEP25).

[0223] On the other hand, the duration of the out-of-seat state is measured. If the duration of the out-of-seat state exceeds the specified time (for example, less than 15 seconds (however, it can also be a value different from the specified time for re-sitting judgment in STEP02)) (STEP22 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP23).

[0224] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP 21 is YES), if the user is detected to be sitting down again (STEP 22 is NO) before the duration of the vacant state exceeds the specified time for re-sitting (for example, less than 15 seconds), the accumulated time calculated (updated) by STEP 25 is subtracted from the time required so far (for example, initially 30 seconds) to obtain a new required time (STEP 26), and on this basis, the elapsed time is measured again by the timer 95 (return to STEP 13).

[0225] After the stable estimated time has passed and before the required time (for example, initially 30 seconds) has passed (STEP 14 is NO), the electrostatic sensor 50 does not detect that the user has left the seat (STEP 21 is NO), and the pulse wave signal remains stable (STEP 31 is NO), wait for the required time (for example, initially 30 seconds) to pass (return to STEP 14).

[0226] After the estimated stabilization time has passed and before the required time (for example, initially 30 seconds) has passed (STEP14 is NO), the electrostatic sensor 50 does not detect that the user has left the seat (STEP21 is NO), and the pulse wave signal becomes temporarily unstable (STEP31 is YES), stop measuring the elapsed time by the timer 95 (STEP32), add the time measured by the timer 95 so far (the duration of the stable state of the pulse wave signal) to the "accumulated time" (initially 0 seconds) (STEP33), and subtract the accumulated time calculated (updated) by STEP33 from the required time so far (for example, 30 seconds) to obtain a new required time (STEP34), and wait for the user's pulse wave signal to reach a stable state again. Figure 14 In order to simplify the diagram, the diagram is shown as returning to STEP42, but unlike the initial STEP42 (determining whether the stable estimated time has passed), it is actually at the process position of STEP42 that it is determined whether the pulse wave signal is stable (although it is the same judgment process as STEP31, but YES / NO is reversed).

[0227] (Sixth Action Example: Effect)

[0228] According to the sixth action example shown above, it is also possible to exclude from the evaluation object the measurement data of the time period until the pulse wave signal (an example of a signal for determining stability) initially becomes stable. On this basis, it is also possible to exclude from the evaluation object the measurement data of the time period when the pulse wave signal (an example of a signal for determining stability) deviates from the stable state due to, for example, the "exertion" or other "body movements" of the user while using the toilet. Therefore, it is also possible to provide an evaluation result that more accurately reflects the user's actual health indicators.

[0229] Furthermore, according to the sixth operation example described above, the determination of the passage of a predetermined sitting time is used instead of the determination of the pulse wave signal first entering a stable state. This simplifies the signal state determination processing flow (procedure).

[0230] (Action Example 7: Function)

[0231] Regarding the toilet system 10 of this embodiment, use Figure 15The seventh operation example is described. Figure 15 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0232] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the predetermined time (e.g., 30 seconds) has elapsed (STEP 53).

[0233] Before the prescribed time has passed (STEP53 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the prescribed time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0234] Before the predetermined time has elapsed (NO in STEP 53 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the predetermined time to elapse (returns to STEP 53 ).

[0235] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the prescribed time to pass (return to STEP53).

[0236] After the predetermined time has elapsed (STEP 53: YES), if the electrostatic sensor 50 detects that the user has left their seat (STEP 54: YES), the control unit 70 determines the measurement results (measurement data) of the laser sensor 40 for a predetermined time (e.g., 30 seconds) measured backward from the user's seat departure (STEP 55). The control unit 70 then outputs the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for the predetermined time (STEP 56).

[0237] After the predetermined time has elapsed (YES in STEP 53 ), while the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 54 ), the process waits for the electrostatic sensor 50 to detect that the user has left the seat (returning to STEP 53 ).

[0238] (Action Example 7: Effect)

[0239] According to the seventh action example shown above, by utilizing the measurement data of the time period at the end of toilet seat use (second half) when the user is more likely to be in a quiet state, it is possible to provide an evaluation result that more accurately reflects the user's actual stable reflection health index.

[0240] (Action Example 8: Function)

[0241] Regarding the toilet system 10 of this embodiment, use Figure 16 The eighth operation example is described. Figure 16 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0242] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the predetermined time (e.g., 30 seconds) has elapsed (STEP 53).

[0243] Before the prescribed time has passed (STEP53 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the prescribed time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0244] Before the predetermined time has elapsed (NO in STEP 53 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the predetermined time to elapse (returns to STEP 53 ).

[0245] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the prescribed time to pass (return to STEP53).

[0246] After the predetermined time has elapsed (STEP 53 returns YES), if the electrostatic sensor 50 detects that the user has left their seat (STEP 54 returns YES), the control unit 70 determines the measurement results (measurement data) of the laser sensor 40 related to the time the pulse wave signal remained stable for a predetermined period (e.g., 30 seconds) measured back from the user's departure (STEP 55'). The control unit 70 then outputs the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for this predetermined period (STEP 56').

[0247] After the predetermined time has elapsed (YES in STEP 53 ), while the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 54 ), the process waits for the electrostatic sensor 50 to detect that the user has left the seat (returning to STEP 53 ).

[0248] (Action Example 8: Effect)

[0249] According to the eighth action example shown above, by utilizing the measurement data of the time period at the end stage (second half) of toilet seat use when the user is likely to be in a quiet state, and on this basis, setting appropriate "stability judgment conditions" for the evaluation of stable reflection-type health indicators (health indicators that are well reflected in the measurement signals in a stable state), the measurement data of the time period that does not meet the stability judgment conditions can be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual stable reflection-type health indicators.

[0250] (Action Example 9: Function)

[0251] Regarding the toilet system 10 of this embodiment, use Figure 17 The ninth operation example is described. Figure 17 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0252] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the predetermined time (e.g., 30 seconds) has elapsed (STEP 53).

[0253] Before the prescribed time has passed (STEP53 is NO), when the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the prescribed time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0254] Before the predetermined time has elapsed (NO in STEP 53 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the predetermined time to elapse (returns to STEP 53 ).

[0255] Even if the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the prescribed time to pass (return to STEP53).

[0256] After the prescribed time has passed (STEP 53 is YES), when the electrostatic sensor 50 detects that the user has left the seat (STEP 54 is YES), the control unit 70 determines the measurement result (measurement data) of the laser sensor 40 related to the prescribed total time (accumulated time if there is an interruption time in the middle, for example, 20 seconds) during which the pulse wave signal maintains a stable state within the prescribed time (for example, 30 seconds) obtained by looking back from the user leaving the seat (STEP 55"). In addition, the control unit 70 outputs the evaluation result of the "stable reflection type health index" calculated based on the measurement data of the prescribed time (STEP 56").

[0257] After the predetermined time has elapsed (YES in STEP 53 ), while the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 54 ), the process waits for the electrostatic sensor 50 to detect that the user has left the seat (returning to STEP 53 ).

[0258] (Action Example 9: Effect)

[0259] According to the 9th action example shown above, since the measurement data of the time period at the end stage (second half) of the set measurement time of the sensor in which the user is likely to be in a quiet state is utilized, and the measurement data of the time period that does not meet the stability judgment conditions can be excluded from the evaluation object, and on this basis, a sufficient amount of measurement data corresponding to the specified total time is used, it is possible to provide an evaluation result that more accurately reflects the user's actual stability-reflecting health indicator.

[0260] (Action Example 10: Function)

[0261] Regarding the toilet system 10 of this embodiment, use Figure 18 The 10th operation example is described. Figure 18 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0262] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the set measurement time (e.g., 90 seconds) has elapsed (STEP 63).

[0263] Before the set measurement time has passed (STEP63 is NO), when the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0264] Before the set measurement time has elapsed (NO in STEP 63 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the set measurement time to elapse (returns to STEP 63 ).

[0265] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the set measurement time to pass (return to STEP63).

[0266] If the set measurement time has elapsed (YES in STEP 63), the control unit 70 confirms the measurement results (measurement data) of the laser sensor 40 for a predetermined time (e.g., 30 seconds) measured backward from the end of the set measurement time (STEP 65). Furthermore, the control unit 70 outputs the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for the predetermined time (STEP 66).

[0267] (Action Example 10: Effect)

[0268] According to the 10th action example shown above, by utilizing the measurement data of the time period at the end stage (second half) of the set measurement time of the sensor when the user is likely to be in a resting state, it is possible to provide an evaluation result that more accurately reflects the user's actual stable reflection-type health indicator.

[0269] (Action Example 11: Function)

[0270] Regarding the toilet system 10 of this embodiment, use Figure 19 The 11th operation example is described. Figure 19 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0271] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the set measurement time (e.g., 90 seconds) has elapsed (STEP 63).

[0272] Before the set measurement time has passed (STEP63 is NO), when the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0273] Before the set measurement time has elapsed (NO in STEP 63 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the set measurement time to elapse (returns to STEP 63 ).

[0274] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the set measurement time to pass (return to STEP63).

[0275] If the set measurement time has elapsed (STEP 63 returns YES), the control unit 70 determines the measurement results (measurement data) of the laser sensor 40 related to the time the pulse wave signal maintained a stable state during a predetermined period (e.g., 30 seconds) measured backward from the end of the set measurement time (STEP 65'). Furthermore, the control unit 70 outputs the evaluation result of the "stability-reflecting health index" calculated based on the measurement data for the predetermined period (STEP 66').

[0276] (Action Example 11: Effect)

[0277] According to the 11th action example shown above, by utilizing the measurement data of the time period at the end stage of the measurement time of the sensor in which the user is likely to be in a resting state, and on this basis, setting a "stability judgment condition" appropriate for the evaluation of stable reflection type health indicators (health indicators that are well reflected in the measurement signal in a stable state), the measurement data of the time period that does not meet the stability judgment condition can be excluded from the evaluation object, thereby providing an evaluation result that more accurately reflects the user's actual stable reflection type health indicators.

[0278] (Action Example 12: Function)

[0279] Regarding the toilet system 10 of this embodiment, use Figure 20 The 12th operation example is described. Figure 20 The control unit 70 first determines whether the user is sitting on the seating surface 21 (STEP 11). If it is determined that the user has not sat on the seating surface 21 (STEP 11: NO), the determination process is repeated.

[0280] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the timer 95 begins measuring elapsed time (STEP 51) and begins recording measurement data obtained from the sensor data 40 (STEP 52). The control unit 70 then begins estimating whether the set measurement time (e.g., 90 seconds) has elapsed (STEP 63).

[0281] Before the set measurement time has passed (STEP63 is NO), when the electrostatic sensor 50 detects that the user has left his seat (STEP01 is YES), the duration of the seat-leaving state is measured. If the duration of the seat-leaving state exceeds the specified time for re-sitting determination (for example, less than 15 seconds) (STEP02 is YES), the control unit 70 causes the communication unit 75 (health indicator output unit) to stop outputting the evaluation results of the "stable reflection type health indicator" (STEP03).

[0282] Before the set measurement time has elapsed (NO in STEP 63 ), the electrostatic sensor 50 has not detected that the user has left the seat (NO in STEP 01 ), and the process waits for the set measurement time to elapse (returns to STEP 63 ).

[0283] Even if the electrostatic sensor 50 detects that the user has left the seat (STEP01 is YES), if the user is seated again (STEP02 is NO) before the vacant state lasts longer than the re-sitting determination time (for example, less than 15 seconds), the process waits for the set measurement time to pass (return to STEP63).

[0284] When the set measurement time has passed (STEP63 is YES), the control unit 70 determines the measurement result (measurement data) of the laser sensor 40 related to the specified total time (accumulated time if there is an interruption time in the middle, for example, 20 seconds) during which the pulse wave signal maintains a stable state within the specified time (for example, 30 seconds) obtained by looking back from the end of the set measurement time (STEP65"). In addition, the control unit 70 outputs the evaluation result of the "stable reflection type health index" calculated based on the measurement data of the specified time (STEP66").

[0285] (Action Example 12: Effect)

[0286] According to the 12th action example shown above, since the measurement data of the time period at the end stage of the set measurement time of the sensor in which the user is likely to be in a quiet state is utilized, and the measurement data of the time period that does not meet the stability judgment condition can be excluded from the evaluation object, and on this basis, a sufficient amount of measurement data corresponding to the specified total time is used, it is possible to provide an evaluation result that more accurately reflects the user's actual stability-reflecting health indicator.

[0287] (Operation Examples 1 to 6: Common Actions and Effects)

[0288] Furthermore, as described above, in this embodiment, the comparison result between the "stability-reflecting health index" newly evaluated by the health index calculation unit 60 (an example of a health index evaluation unit) and the "stability-reflecting health index" evaluated in the past can be output.

[0289] Thus, the user of the toilet system 10 of the present embodiment can understand the current health index while referring to the comparison results with past health indexes every time the user uses the toilet in daily life.

[0290] In addition, in the present embodiment, the comparison result between the "stability-reflecting health index" most recently evaluated by the health index calculation unit 60 (an example of a health index evaluation unit) and a predetermined threshold value can be output.

[0291] Thus, the user of the toilet system 10 of this embodiment can intuitively understand whether the current health index is satisfactory every time he uses the toilet in daily life. For example, the health index can be evaluated as a score value from 0 to 100.

[0292] (First to Sixth Operation Examples: Modifications)

[0293] In the aforementioned first to sixth operation examples, in STEP 03, the output of the evaluation result of the "stability-reflecting health index" is stopped. However, instead of this, the control unit 70 may cause the communication unit 75 (health index output unit) to output error information.

[0294] The output of this error information may be performed together with the output of the "stability-reflecting health index" (which is highly likely to be incorrectly calculated), or may be performed instead of the output of the "stability-reflecting health index".

[0295] Similarly, in STEP 23, the output of the evaluation result of the "stability-reflecting health index" is also stopped. However, instead of this, the control unit 70 may cause the communication unit 75 (health index output unit) to output error information.

[0296] The output of this error information may be performed together with the output of the "stability-reflecting health index" (which is highly likely to be incorrectly calculated), or may be performed instead of the output of the "stability-reflecting health index".

[0297] In addition, in STEP 15, the evaluation result of the "stable reflection type health index" calculated based on the measurement data equivalent to the required time (for example, 30 seconds) is output. However, when the duration of the pulse wave signal maintaining a stable state (the cumulative time when there is an interruption time in the middle) is longer than the required time (for example, 30 seconds), the evaluation result of the "stable reflection type health index" calculated based on all these measurement data can also be output, or only the time period of "more stable state" equivalent to the required time (for example, 30 seconds) can be selected to output the evaluation result of the "stable reflection type health index" calculated based on these measurement data.

[0298] That is, the health index calculation unit 60 (an example of a health index evaluation unit) can also evaluate the user's health index based on the measurement data of the laser sensor 40 related to the time period during which the pulse wave signal (an example of a signal for stability judgment) meets the specified stability judgment condition and the time period during which the pulse wave signal further meets the second specified stability judgment condition.

[0299] Thus, the second predetermined stability determination condition can be used to selectively and effectively apply a more advanced state of the user's "resting state", thereby providing an evaluation result of the "stability-reflecting health index" that more accurately reflects the user's actual state.

[0300] Specifically, for example, the second predetermined stability determination condition may be that the fluctuation of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value during one cycle is within ±5%.

[0301] (7th to 12th Operation Examples: Modifications)

[0302] In the aforementioned action examples 7 to 12, the output of the evaluation result of the "stable reflection type health index" is stopped in STEP03, but instead of the above action, the control unit 70 can cause the communication unit 75 (health index output unit) to output error information.

[0303] The output of this error information may be performed together with the output of the "stability-reflecting health index" (which is highly likely to be incorrectly calculated), or may be performed instead of the output of the "stability-reflecting health index".

[0304] In addition, in STEP65" and STEP66" (the 12th action example), the evaluation result of the "stable reflection type health index" calculated based on the measurement data equivalent to the specified total time (for example, 20 seconds) is output. However, if the duration (cumulative time if there is an interruption time in the middle) of the pulse wave signal maintaining a stable state within the specified time (for example, 30 seconds) is longer than the specified total time (for example, 20 seconds), the evaluation result of the "stable reflection type health index" calculated based on all the above measurement data can also be output, or a time period of "more stable state" equivalent to the second total time (for example, 25 seconds) can be selected to output the evaluation result of the "stable reflection type health index" calculated based on these measurement data.

[0305] That is, in this case, the health index calculation unit 60 (an example of a health index evaluation unit) can also evaluate the user's health index based on the measurement data of the laser sensor 40 related to the time period during which the pulse wave signal (an example of a signal for stability judgment) meets the specified stability judgment condition and the time period during which the pulse wave signal further meets the second specified stability judgment condition.

[0306] Thus, the second predetermined stability determination condition can be used to selectively and effectively apply a more advanced state of the user's "resting state", thereby providing an evaluation result of the "stability-reflecting health index" that more accurately reflects the user's actual state.

[0307] Specifically, for example, the second predetermined stability determination condition may be that the fluctuation of the pulse wave signal from a certain minimum value to a maximum value and then to the next minimum value during one cycle is within ±5%.

The programs and the storage medium storing the programs are also protected by the present application.

[0310] For example, the program involved in the present invention uses a toilet system 10 to provide evaluation results of health indicators, and the toilet system 10 has: a toilet seat 20, which has a seating surface 21 for a user to sit on; a laser sensor 40, which measures physical quantities reflecting the user's blood flow information; a health indicator calculation unit 60 (health indicator evaluation unit), which evaluates the user's health indicator based on the measurement results of the laser sensor 40; and a communication unit 75 (health indicator output unit), which outputs the user's health indicator evaluated by the health indicator calculation unit 60. The program is characterized in that by executing the program by a computer, the following process can be implemented, that is, the user's health indicator is evaluated based on the measurement results of the laser sensor 40 related to the time period in which the pulse wave signal obtained by processing the measurement signal of the laser sensor 40 meets the specified stability judgment condition.

The program is characterized in that by executing the program by a computer, the following process can be implemented, namely, evaluating the health indicator of the user based on the measurement results of the laser sensor 40 related to a specified time obtained by going back to the time when the user finishes using the toilet seat and leaves the toilet seat.

[0312] Alternatively, for example, the program involved in the present invention uses a toilet system 10 to provide evaluation results of health indicators, wherein the toilet system 10 has: a toilet seat 20, which has a seating surface 21 for a user to sit on; a laser sensor 40, which measures physical quantities reflecting blood flow information of the user; a health indicator calculation unit 60 (health indicator evaluation unit), which evaluates the health indicator of the user based on the measurement results of the laser sensor 40; and a communication unit 75 (health indicator output unit), which outputs the health indicator of the user evaluated by the health indicator calculation unit 60. The program is characterized in that by executing the program by a computer, the following process can be implemented, namely, the health indicator of the user is evaluated based on the measurement results of the laser sensor 40 related to a specified time obtained by backtracking from the end of the set measurement time of the laser sensor 40.
