Description

Body weight measuring apparatus, body weight measuring system, and method of controlling body weight measuring apparatus

The present invention relates to a weight measuring device for measuring the weight of a person to be measured.

In recent years, it has been widely recognized that daily health management is important as a preventive measure against lifestyle-related diseases. And by measuring and recording biological information such as body temperature, body weight, body fat (including visceral fat), bone density, blood pressure, or amount of exercise (steps, calorie consumption, etc.) on a daily basis, It is attracting attention to manage their own health.

Conventionally, most of the above-described biometric information has been measured using dedicated devices installed in medical / health institutions such as hospitals and health centers. In addition, healthcare-related devices that can be easily used in public facilities such as homes, sports facilities, and shopping centers are widely used in the private sector for daily health management by users (measured persons). Examples of such devices include a weight scale, a body fat scale, a thermometer, a heart rate monitor, a pulse wave meter, and a blood pressure monitor.

Especially, weight measurement has been used for health management. Patent Document 1 discloses a chair weight scale. Since the weight measuring apparatus is provided in the seat part, the weight scale for chairs of patent document 1 can measure a body weight in the state in which the user sat on the seat part. Therefore, even if the user's foot is inconvenient, the weight can be easily measured.

Embodiment 1
(Appearance and schematic configuration of weight scale 100)
First, an example of the appearance and schematic configuration of a weight scale (weight measuring device) 100 according to the present invention will be described with reference to FIG. (A) of FIG. 2 is the schematic which looked at the user (measured person) 50 sitting on the weight scale 100 and the weight scale 100 from the side.

The scale 100 has a communication function with the display unit (display device) 20, the device (measuring device) 4, and a sensor (detection unit) 40 that detects a preparation state (use state) by the user of the device 4. ing. Hereinafter, a case where the scale 100 further includes a camera (imaging unit) 107 that captures the sitting user 50 and the like will be described as an example, but the camera 107 is not an essential configuration. Note that the weight scale 100 according to the present invention may be applied as a health support system that allows measurement of biological information by each device and management of biological information while the user 50 is in a prone position. That is, the health support system is not limited to the posture of the user 50. For example, in the health support system, a bed type in which the user 50 is sleeping on a bed or a mattress may be used. However, since some of the measured biological information is greatly influenced by the posture of the user 50, in health care, it is desirable to measure without changing the posture when measuring biological information.

There are no particular restrictions on the height and age of the user 50 who uses the scale 100, and a wide range of age groups from adults to children can be used. If the user 50 understands the basic operation method and can use it safely, the user 50 can use the scale 100 alone. However, when many unspecified users 50 use the weight scale 100, it is desirable to arrange the staff supporting the user 50 near the weight scale 100. Accordingly, it is possible to perform an appropriate treatment on the user 50 who complains of a change in physical condition during measurement of biological information.

A weight scale 100 shown in FIG. 2A is a weight scale that can measure a plurality of pieces of biological information of the user 50 just by sitting and can present the result on the display panel 30 so that the user 50 can confirm the result. is there. Here, the biological information may be information for which each device 4 determines a numerical value or a measurement result, such as weight, body fat, body temperature, blood pressure, number of heartbeats, pulse wave, number of steps, amount of activity, and the like. It may be a test result of sensory functions such as vision (sight), olfaction, hearing, and touch. The pulse wave is a method for measuring the blood flow volume of the capillaries at the fingertips and toes and examining the degree of arteriosclerosis. Such biological information is measured by the weight scale 100 and each device 4.

In addition, (a) of FIG. 2 does not show all the devices (measuring devices) 4 but shows only the sphygmograph 4p attached to the fingertip of the user 50 as an example. However, the present invention is not limited to this, and various devices 4 can be applied. Examples of devices that can be used as the device 4 include, but are not limited to, a blood pressure monitor 4a (see FIG. 3 and the like), a pulse wave meter 4p, an expiration sensor, a bone densitometer, a thermometer, a blood glucose meter, Examples thereof include a body composition meter, a stethoscope, a body sound sensor, a face recognition sensor, a smile recognition sensor, a touch panel sensor, and a camera distance sensor.

The weight scale 100 is a chair provided with a seating surface (support surface) 101, a back (backrest) 102, an armrest (armrest) 103, and a footrest (footrest) 104. Between the seat surface 101 and the floor surface F, there are a support portion 108 that supports the main body of the weight scale 100 and an installation member 109 that is disposed at a contact portion between the floor surface F and the main body of the weight scale 100. ing.

The height of the seat surface 101 from the floor surface F can be adjusted by an elevating function provided in the support unit 108. Thereby, the height of the seating surface 101 can be adjusted to a height that is easy to sit for users of various body types and a wide range of ages.

The angle between the seat surface 101 and the backrest 102 defines the posture of the user 50 sitting on the weight scale 100. In general, in measurement of biological information such as blood pressure, measurement in a relaxed state is preferable. Therefore, the backrest 102 is inclined backward with respect to the seat surface 101, and the posture (the posture or the posture close to the prone position) that the seat surface 101 and the backrest 102 support from the back of the user 50 to the buttocks is selected. be able to.

2A, the armrest 103 is connected to the support portion 108 by, for example, a connecting member 105a. Moreover, the footrest 104 is connected with the support part 108 by the connection member 105b, for example.

The scale 100 can be attached with various detachable devices 4. For example, the armrest 103 is suitable as a position where the device 4 is attached. The device 4 is not limited to the device 4 attached to the scale 100. Furthermore, the device 4 may not be the device 4 directly attached to or fixed to the scale 100, can measure biological information, and transmit / receive data to / from the scale 100. As long as the device 4 is installed at a position capable of

Each device 4 can communicate with the weight scale 100 and may notify the weight scale 100 of information indicating that each device 4 has started measurement or has finished measurement. Thereby, the scale 100 can determine the timing for measuring the body weight according to the measurement situation such as whether the measurement by each device 4 is before the start, whether the measurement is being performed, or whether the measurement is completed. .

In addition, each device 4 may include a sensor (detection unit) 40 that detects a preparation state (use state) on the user 50 side (measured person side) such as how the user 50 is worn. . Each device 4 acquires a detection signal of the sensor 40 included in the device itself, determines whether or not measurement of biological information is measurable, and starts measurement when the preparation state satisfies a predetermined condition. . The detection signal of the sensor 40 may be transmitted to the weight scale 100 or instructs the weight scale 100 to measure the weight. Thereby, the scale 100 can determine the timing which measures a body weight based on the preparation state of each apparatus 4. FIG. Note that it is not an essential configuration that each device 4 includes the sensor 40. For example, a sensor that can be directly attached to the device 4 that does not include the sensor 40 or that can be installed at a position where the state of the device 4 can be detected may be applied as the sensor 40. Thereby, it can be comprised so that the weight scale 100 may receive the preparation state of the arbitrary apparatuses 4 with which the weight scale 100 is provided.

As described above, the process in which the weight scale 100 determines the timing for measuring the weight according to the measurement status of each device 4 or the preparation state of each device 4 will be described in detail later.

In addition, the position of the armrest may be adjusted so that the shoulder of the user 50 sitting on the weight scale 100 is in a natural position (height) (for example, a distance from the seating surface). Thereby, the height of the device 4 that measures the pulse rate, blood pressure, or pulse wave can be adjusted to be substantially equal to the height of the heart of the user 50 who is the subject. .

Since the footrest 104 is connected to the support portion 108 by the connecting member 105b, the entire weight of the user 50 sitting on the weight scale 100 is supported by the support portion 108. That is, the user 50 sitting on the weight scale 100 is in a state where the whole body is completely placed on the weight scale 100. The user 50 sitting on the weight scale 100 can maintain a resting posture while sitting on the weight scale 100. Various devices 4 that measure biological information from the soles, ankles, and the like of the user 50 can be installed on the footrest 104.

Note that the footrest 104 is not an essential component of the weight scale 100. For example, when measuring the weight of the user 50 sitting on the scale 100, a step (not shown) where the legs of the user 50 are separated from the floor surface F or connected to the support unit 108. You may sit down with your feet on the top.

The support unit 108 is provided with a measuring unit (weight measuring unit) 14 (see FIG. 1 and the like) of the weight scale 100, and the weight of a part of the weight scale 100 is measured by the user 50 sitting on the weight scale 100. The total plus weight is measured. The weight of the user 50 can be calculated by subtracting the weight of only the weight scale 100 before the user 50 is seated from the measured total weight. Note that, as in a general health checkup, the amount of clothing may be corrected. For example, a value obtained by subtracting a predetermined weight (1 kg) from the measured weight as the amount of clothing may be used as the body weight. Further, as described above, when the device 4 attached to the armrest 103 is changed (replaced), the weight considering only the weight of the device 4 attached to the scale 100 is changed every time the device 4 is changed. The measured body weight may be used. The support unit 108 may include a sensor that can detect the position of the center of gravity of the sitting user 50 and movement, and may determine whether the posture of the user 50 is stable. . The scale 100 that accurately measures the weight of the user 50 will be described in detail later.

The display device 20 is a display device having a display panel 30 that displays acquired information, and is supported by a position adjustment unit (adjustment unit, height adjustment unit) 106. The position adjusting unit 106 is a member for supporting the display device 20 and changing the position of the display device 20. That is, the relative positional relationship between the display device 20 and the user 50 can be adjusted by the position adjustment unit 106. Note that the position of the display device 20 may be adjusted by an operation by the user 50, or the scale 100 may automatically adjust based on biological information such as the sitting height, shoulder width, and visual acuity of the user 50. Good. Similar to the position of the display device 20, the orientation of the display panel 30 can also be freely changed.

A touch panel (not shown) is superimposed on the display panel 30 and accepts a touch operation by the user 50. The display device 20 receives biological information measured by each device 4 or various test results, displays the received information, test results, and the like and presents them to the user 50. Details of how to use the display device 20 in the scale 100 will be described later.

The weight scale 100 is not an essential component, but may further include a speaker (not shown), and may play favorite music so that the user 50 receiving the measurement can relax. The weight scale 100 is not an essential configuration, but may further include a microphone (not shown), and a configuration in which the sitting user 50 can talk with a medical staff or an operator. Also good. An example of a usage method using a speaker and a microphone will be described later together with an example of a usage method in the scale 100 when a communication function is used.

(Display device 20 and camera 107)
Next, a schematic configuration of the display device 20 will be described. A touch panel is superimposed on at least a part of the display panel 30 of the display device 20 included in the scale 100, and input by a touch operation on the display panel 30 is possible. That is, the display device 20 functions as a user interface that displays information and receives a touch operation by the user 50. The display panel 30 can also display a list of each measured biological information for the user 50 sitting on the weight scale 100. When the user 50 finds a measured value that is significantly different from the measured value or the past measured value, the user 50 can also instruct re-measurement by a touch operation on the display panel 30. That is, the user 50 may be configured to individually instruct measurement of biological information by each device by a touch operation on the display panel 30.

The display device 20 presents information related to biological information measured by each device 4 from the scale 100 and the device 4 and displays the information to the user 50.

The camera 107 is provided in the display device 20, and at least a part of the body such as the face or upper body of the user 50 sitting on the scale 100 can be photographed. A part of the backrest 102 and the surface of the user 50 as well as the upper body of the user 50 can be photographed by the camera 107. Note that the entire body of the user 50 may be captured by the camera 107.

The camera 107 is a digital camera, and is a camera module that captures an imaged person such as the user 50 sitting on the scale 100 using a CCD sensor, a CMOS sensor, or the like. A camera view image that is an image optically input through the camera 107 and shooting data obtained by shooting are output to the display device 20. The camera 107 is not necessarily provided in the scale 100. For example, the camera 107 may be an external device that has a communication function in the same manner as each device 4, receives a control signal from the scale 100, and can take a picture according to the signal. The position where the camera 107 is installed may be installed anywhere as long as the above object can be achieved.

The image data photographed by the camera 107 may be used for image analysis processing. For example, the image data of the user 50 sitting on the weight scale 100 is analyzed, and the length of a part of the body of the user 50 (for example, sitting height, height, etc.) or the state of the body (shoulder position, Posture). The posture information may be stored in the weight scale 100 so that the posture of each user 50 when sitting on the weight scale 100 can be registered. According to this configuration, the posture when measuring biological information can be kept constant. Therefore, the reliability of the measured biological information can be maintained high. In addition, you may comprise so that the measurement of biometric information may not be started until an attitude | position is settled in the tolerance | permissible_range.

If the hardness of the material of the seat surface 101 is excessively soft, it will sink deep due to the weight of the user 50, so there is a possibility that the seat height and the like cannot be measured correctly. On the other hand, the seat surface 101 made of a hard material having almost no elasticity makes the sitting comfort worse, and the attractiveness of the scale 100 is reduced. Therefore, although not limited thereto, it is desirable to apply a low-repulsion material to the seating surface 101 to ensure the accuracy of the measurement result without impairing the sitting comfort.

For example, the camera 107 may use the fact that the attitude of the user 50 is not changed for a predetermined time (for example, 5 seconds) as a trigger for shooting, or to prompt the user 50 to send a signal that can be shot. A touch button such as “shooting OK” may be displayed on the display panel 30, and after the touch button is pressed, shooting may be performed after a predetermined time (for example, 2 seconds). Or, a button with the character string “Start” is displayed on the screen together with the character string “Start Healthcare Check. Touch the Start button.” The “Start” button The depression may be used as a trigger for starting shooting.

(How to use scale 100 when using communication function)
When a medical examination is received at a medical facility such as a hospital, wait for the turn and measure the height, weight, blood pressure, etc. in order. The equipment 4 that performs each measurement is usually installed in a separate place, and it is necessary to move in order by holding a sheet for entering measurement data. On the other hand, the weight scale 100 can measure the height, weight, body temperature, blood pressure, pulse wave, etc. of the user 50 while sitting on a chair. The obtained data is automatically communicated from the measured device 4 to the scale 100, displayed on the display panel 30 of the display device 20, and presented to the user 50.

The display device 20 may receive information to be displayed from the scale 100 via a communication network, or may receive information to be displayed via wireless or wired communication (local network). That is, the display device 20 is not necessarily provided integrally with the weight scale 100. For example, you may transmit to the portable terminal of the family who is going out or lives away. Thereby, the family can check the biometric information measured by the user 50. For example, the health condition of an elderly person can be confirmed by a family living in a remote place as appropriate, and when a change in the health condition occurs, it can be found and dealt with early.

The scale 100 transmits information to be displayed to a plurality of display devices (including the display device 20) via the communication network. For example, it may be configured to be able to transmit to a display device (not shown) used by a medical staff such as a doctor or nurse in a hospital away from a place where the scale 100 is installed, or a family member. Thereby, the doctor of a remote place can also confirm the measured biometric information. Therefore, the user 50 sitting on the weight scale 100 can receive a diagnosis from a remote doctor based on the displayed biological information.

The weight scale 100 may be provided with a plurality of display devices 20. For example, at least one display device 20 among the plurality of display devices 20 may be a display device 20 that uses bidirectional image communication. The other display device displays an image of a doctor or the like that is a communication partner, displays measured biometric information, or displays images such as data or data provided by the doctor. Also good.

By providing a plurality of display devices 20 in this way, it is possible to consult with a doctor at a remote place via a communication network to hear their findings and receive useful advice about health. . When using bidirectional communication in this way, the position of the camera may be moved so that the face of the user 50 is photographed.

Furthermore, remote operation from a doctor, a caregiver, or a family registered by the user 50 may be possible using the communication function described above. For example, the position of the camera 107 of the scale 100 and the shooting direction, the position and direction of the display device, the zoom function, etc. are remotely operated to find the part to be observed (for example, skin, eyes, tongue, fingertip, etc.) May be obtained. Moreover, you may comprise so that the measurement of a user's biometric information by each apparatus 4 can be started remotely. Thereby, if a user wears each device 4 used for measuring living body information as displayed on display device 20, measurement of living body information will be started. Therefore, it is possible to transmit biometric information necessary for health maintenance and medical examination, which is required by a doctor at a remote place, to the user 50 and prompt measurement of the biometric information.

(Main components of the scale 100)
The embodiment of the present invention will be described below with reference to FIGS. 1 and 3 to 6. For convenience of explanation, members having the same functions as those already described above are given the same reference numerals and explanation thereof is omitted.

The weight scale 100 can measure the weight, blood pressure, pulse wave, and the like of the user 50 sitting on the seat surface 101 all at once or sequentially. Here, a weight scale 100 that measures the weight of the user 50 when the measurement by the device 4 that measures the biological information of the user 50 can be started will be described with reference to FIG. FIG. 1 is a block diagram illustrating an example of a main part configuration of a weight scale 100 according to Embodiment 1 of the present invention. In FIG. 1, the display device 20 includes the sensor 40 of the device 4 having a communication function with the scale 100 and a display panel 30 (see FIG. 2B) that displays the measured weight. It also shows.

The weight scale 100 includes a seat surface 101 on which the user 50 sits, a measurement unit 14 that measures the weight of the user 50 when the user 50 sits on the seat surface 101, and a user when the user 50 sits on the seat surface 101. The device 4 that measures 50 biological information, the sensor 40 that detects the state of preparation on the user 50 side for the device 4 to start measuring biological information, and the sensor 40 has completed preparation on the user 50 side After the state is detected, a measurement value acquisition unit 13 that causes the measurement unit 14 to measure the body weight is provided.

The sensor 40 detects that the preparation operation by the user 50 necessary for the device 4 to measure the biological information is completed. Here, the preparation operation by the user 50 necessary for the device 4 to measure the biological information is specifically various members (not shown) used by the device 4 to measure the biological information of the user 50. Are properly mounted according to a predetermined rule, or a predetermined button (for example, a button for instructing the start of measurement) is pressed when ready to start measurement. That is, when it is detected that this operation is completed, it means that preparation for starting measurement by the device 4 including the sensor 40 is ready. The sensor 40 functions as a sensor that detects that these operations have been performed, and transmits the detected signal (sensor signal) to the weight scale 100. Thereby, the scale 100 can determine that the measurement of the biological information by the device 4 can be started (can be started).

That is, the sensor signal from the sensor 40 may be a sensor signal indicating that the device 4 has been correctly set by the user 50, or a button for accepting a press by the user 50 or a touch operation by the user 50. It may be a sensor signal indicating that a received touch panel or the like has been operated.

In order to detect that the device 4 correctly mounts various members used for measuring the biological information of the user 50 in accordance with a predetermined rule, the device 4 may include the sensor 40 or the external sensor 40 may be installed. May be used. The sensor 40 is not limited to this, but is a light (infrared ray, visible ray) sensor, a pressure sensor, a distance measuring sensor, an image recognition function using an image taken by a camera, a temperature sensor, a sound wave sensor, a touch. (Contact) sensors, proximity sensors and the like can be applied. The detection of the operation of the user 50 by the sensor 40 will be specifically described later with an example of the sensor 40 provided in the sphygmomanometer 4a.

The sensor signal detected by the sensor 40 may be transmitted to the device 4 and used to control the operation of the device 4.

As shown in FIG. 1, the weight scale 100 includes a reception unit 11, a state determination unit 12, a measurement value acquisition unit (measurement control unit) 13, a measurement unit (weight measurement unit) 14, a device 4, and a sensor 40. Yes. Note that the seat surface 101, a sensor that detects that the user 50 is seated on the seat surface 101, and a configuration that outputs guidance to the user 50 using the device 4 are not directly related to the feature points of the present invention. The illustration is omitted.

The receiving unit 11 receives the sensor signal from the device 4 used by the seated user 50 and the sensor 40 provided in the device 4. Transmission / reception of sensor signals may be performed by wireless communication or wired communication. In addition, although the example provided with one sensor 40 with respect to one apparatus 4 is shown in FIG. 1, it is not limited to this. For example, the number of sensors 40 provided for each device 4 may be one or plural.

The state determination unit 12 determines whether the device 4 is ready to start measurement based on the sensor signal received by the reception unit 11.

The measurement value acquisition unit 13 acquires the value measured from the measurement unit 14 when acquiring a determination result indicating that the device 4 is ready to start measurement from the state determination unit 12. In addition, the measurement value acquisition unit 13 outputs the acquired weight of the user to the display device 20.

The measurement unit 14 measures the weight of the user 50 and outputs the measurement result to the measurement value acquisition unit 13. The measurement unit 14 may be incorporated in the main body of the weight scale 100 like each device 4 or may be installed at a position different from the main body of the weight scale 100. When the measurement unit 14 is installed at a position away from the main body of the weight scale 100, the measurement unit 14 has a communication function with the weight scale 100. In addition, the number of the measurement parts 14 with which the weight scale 100 is provided is not limited to one like the number of the apparatuses 4. For example, the weighing unit 100 may include a plurality of measuring units 14 having a function of communicating with the weighing scale 100 so that the weights of a plurality of users 50 can be measured at a time.

The measurement unit 14 receives an instruction to start measuring the body weight from the measurement value acquisition unit 13, then measures a value indicating the weight of the user 50 and transmits the measured value to the measurement value acquisition unit 13. You may comprise as follows. For example, when the user 50 sits on the scale 100, a transient large impact may be applied to the measurement unit 14. When the measurement unit 14 is measuring when receiving the impact, there is a possibility that the weight of the user 50 cannot be measured accurately or damaged due to failure. However, according to the above configuration, when a large impact is transiently applied to the measurement unit 14, the measurement unit 14 does not measure the weight, and when the weight measurement can be started, the measurement unit 14 is activated and the body weight is measured. Thereby, the measurement part 14 can be protected from a failure and damage.

The display device 20 displays the weight output from the measurement value acquisition unit 13 on the display panel 30.

As described above, the weight scale 100 includes the measurement unit 14 that measures the weight of the user 50, and the sensor signal from the sensor 40 that detects the usage state of the one or more devices 4 that measure the biological information of the user 50. And a state determination unit that determines whether measurement by a predetermined device 4 among devices 4 used by the user 50 can start based on the sensor signal acquired by the reception unit 11 12 and a measurement value acquisition unit 13 that acquires a value indicating the weight of the user 50 from the measurement unit 14 when the state determination unit 12 determines that the measurement by the predetermined device 4 can be started. I have.

According to this configuration, the weight scale 100 measures the weight when the measurement of the biological information by the device 4 used by the user 50 can be started. Thereby, when the user 50 is resting, the weight of the user 50 can be measured. Therefore, it is possible to measure an accurate weight without variation or error.

That is, in a weight measuring apparatus that measures the weight of a person sitting on a seating surface (supporting surface) or lying on a bed (supporting surface), if the posture of the person to be measured changes, the load on the supporting surface Since the manner of application changes, the measured body weight may vary. According to the weight scale 100, such a problem can be solved.

(Sensor 40 of blood pressure monitor 4a)
Next, the sensor 40 that detects the state of the sphygmomanometer 4a used by the user 50 will be briefly described. The sphygmomanometer 4a measures the blood pressure of the user 50 non-invasively (or also called non-invasive). The sphygmomanometer 4a is provided with an annular pressure unit. The pressurizing unit has a function to pressurize the arm of the user 50 when the arm is passed.

The sensor 40 provided in the sphygmomanometer 4a is a sensor that detects whether or not the arm of the user 50 is correctly passed through the pressurizing unit to the upper arm. The sensor 40 is an optical sensor including a light emitting unit such as infrared rays and visible light, and a light receiving unit, and light is emitted from the light emitting unit to the light receiving unit.

Further, the sensor 40 may be an optical sensor retrofitted outside the sphygmomanometer 4a, or may be an optical sensor built in the sphygmomanometer 4a to acquire a measurement preparation state.

The sensor 40 is attached to the side with the hand when the arm of the user 50 is passed through the pressurizing unit, that is, the vicinity of the exit through the pressurizing unit. When the arm of the user 50 is passed, the light emitted from the light emitting unit of the sensor 40 to the light receiving unit is blocked by the user 50 arm. Thus, the sensor 40 can detect that the arm of the user 50 is passed through the pressurizing unit. In addition, when it is requested | required that the upper part of the user 50 can be passed through the pressurizing unit, another sensor such as a contact sensor is placed at a position where the elbow of the arm passed through the pressurizing unit by the user 50 contacts. The sensor 40 may be configured to be used in combination with the above-described optical sensor. Thereby, in addition to simply passing the arm through the pressurizing unit, it is possible to detect that the arm of the user 50 has been passed through the pressurizing unit up to the upper arm unit. That is, the position and number of sensors 40 provided in the sphygmomanometer 4a can be arbitrarily set.

The sensor 40 may be a button provided on the sphygmomanometer that is pressed by the user 50. In this case, when this button is pressed, the sphygmomanometer 4a may start measurement, but is not limited thereto. For example, even if the button is pressed by the user 50, no pressure is applied, and when all the devices 4 (pulse wave meter, etc.) used by the user sitting on the weight scale 100 are ready for measurement, For example, an instruction to start pressurization may be transmitted from the scale 100. The button pressed by the user 50 when the measurement preparation of the sphygmomanometer 4a is completed may be a button that can be attached to or detached from the sphygmomanometer 4a.

(Weighing with scale 100)
Next, a process in which the weight scale 100 including the sphygmomanometer 4a measures the weight of the user 50 will be described with reference to FIGS. FIG. 3 is an image diagram illustrating an example of timing when the weight scale 100 illustrated in FIG. 1 measures the weight of the user 50. FIG. 4 is a flowchart showing a flow of processing until the weight scale 100 measures the weight at the timing shown in FIG. 3 and displays the result.

FIG. 3 is an image diagram showing the transition of operations related to the sphygmomanometer 4a in the upper row and the weight scale 100 in the lower row. Time is flowing from left to right as shown on the bottom axis. That is, FIG. 3 shows the order in which the operation of the sphygmomanometer 4a after the time t0 and the operation of the weight scale 100 are executed. Note that the intervals between the times t0 to t5 and the operations such as “guidance” and “measurement” are merely images, and do not specifically indicate these times.

In FIG. 3, in order to clearly indicate whether the guidance is related to the sphygmomanometer 4a, here, “guidance” is arranged at a position indicating the operation of the sphygmomanometer 4a. That is, the “guidance” is output from the scale 100 to the user 50. However, the present invention is not limited to this, and the apparatus 4 may receive the guidance from the scale 100 and output the guidance to the user 50.

First, when it is detected that the user 50 is seated (sitting) on the seat surface 101 at time t0 shown in FIG. 3 (YES in S1 of FIG. 4), it is shown in FIG. 3 after a predetermined time (such as 10 seconds) has elapsed. At time t1, guidance Ga is output so that the arm is passed through the pressurizing part of the sphygmomanometer 4a (S2 in FIG. 4). This guidance may be output as sound from a speaker (not shown) provided in the scale 100, or may be characters and images displayed on the display device 20.

When the user 50 passes his arm through the pressurization unit of the sphygmomanometer 4a according to the guidance Ga, the sensor 40 transmits a sensor signal indicating whether the arm of the user 50 is passed through the pressurization unit to the weight scale 100 (FIG. 4 corresponds to S3).

The weight scale 100 receives from the sensor 40 of the sphygmomanometer 4a a sensor signal indicating that the preparation on the user 50 side in the sphygmomanometer 4a has been completed (measurement preparation completed) (YES in S4 (detection step) in FIG. 4). The weight measurement result is acquired from the measurement unit 14 at time t5 in FIG. 3 (S5 in FIG. 4: weight measurement step). The result of the weight measurement is displayed on the display device 20 (S6 in FIG. 4).

Blood pressure measurement by the sphygmomanometer 4a may be started when measurement preparation is completed, or may be started after receiving an instruction to start measurement from the weight scale 100.

Even if the user 50 is seated on the seat of the weight scale 100, the user 50 moves his body for a while because of the operation for preparing the blood pressure monitor 4a. As described above, the weight scale 100 can measure the body weight at the timing when the user 50 is rested by measuring the body weight triggered by the ready state of the sphygmomanometer 4a. it can. Therefore, the body weight can be measured without any measurement error due to shaking at the time of measurement.

In addition, although the configuration using only the blood pressure monitor 4a as the device 4 has been described as an example, the configuration is not limited thereto. For example, the configuration may be such that weight measurement is triggered by the completion of measurement preparation of another device 4 such as a pulse wave meter 4p in addition to the blood pressure monitor 4a.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. FIG. 13 is a block diagram showing a modification of the main configuration of the weight scale 100c according to the present invention.

The scale 100c according to the present embodiment is different from the scale 100 shown in FIG. 1 in that a sensor (detection unit) 40c that detects the state of the measurement unit 14c is provided in the measurement unit 14c.

Send instructions to do.

The measuring unit 14c starts measuring the weight of the user 50 in response to an instruction to start measuring the weight from the measured value acquiring unit 13. The measured value indicating the weight of the user 50 is transmitted from the measurement unit 14 c to the measurement value acquisition unit 13. A value indicating the weight of the user 50 may be transmitted from the measuring unit 14c to the receiving unit 11 of the weight scale 100c.

According to this configuration, in addition to the preparation state of each device 4, the preparation state of the measurement unit 14c is also used to control the timing at which weight measurement is started. Accordingly, it is possible to accurately detect that the posture of the user 50 is stable and measure the weight of the user 50 at a timing suitable for measuring the weight.

In addition, the measurement unit 14c includes a communication function with the weight scale 100 (for example, the measurement value acquisition unit 13 and the like), so that the measurement unit 14c instructs the measurement value acquisition unit 13 to start weight measurement. Upon receipt, weight measurement can begin. Thereby, it is possible to control the measurement unit 14c not to measure the body weight when a large impact is applied to the measurement unit 14c, and the measurement unit 14c can be protected from failure and damage.

[Embodiment 3]
Another embodiment of the present invention will be described below with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. FIG. 14 is a block diagram showing a modification of the main configuration of the weight scale 100d according to the present invention.

The weight scale (weight measurement system) 100d according to the present embodiment includes a device 4, a sensor (detection unit) 40 that detects the state of the device 4, a measurement unit (weight measurement unit) 14d, and a sensor that detects the state of the measurement unit 14d. (Detecting unit) 40d, a control device (measurement control unit) 150, and a display device 20 are provided. The device 4, the sensor 40, the measurement unit 14 d, and the sensor 40 d have a communication function with the control device 150, and the device 4 and the measurement unit 14 d are arranged at positions away from the control device 150. Also good.

Sensor 40d detects whether or not the weight of user 50 can be measured. The sensor 40d may be, for example, a pressure sensor that can detect that the user 50 is sitting. Note that it may be built in the measurement unit 14d or provided outside the measurement unit 14d.

The control device 150 includes a reception unit 11d, a state determination unit 12d, and a measurement value acquisition unit 13d. The measurement unit 14d of the weight scale 100d according to this embodiment is different from the weight scale 100c of FIG. 13 and the like in that it is separated from the reception unit 11d, the state determination unit 12d, and the measurement value acquisition unit 13d. The control device 150 may be realized by a server device, a personal computer (PC), a dedicated relay device, or a cloud service.

The receiving unit 11d includes a device 4 used by the user 50 seated on the scale 100d, a sensor signal from the sensor (detection unit) 40 provided in the device 4, and a sensor from the sensor 40d provided in the measurement unit 14d. Receive a signal. Transmission / reception of sensor signals may be performed by wireless communication or wired communication.

The state determination unit 12d determines whether the device 4 is ready to start measurement based on the sensor signal from the sensor 40 received by the reception unit 11d. The state determination unit 12d also determines whether or not the measurement unit 14d is ready to start measurement based on the sensor signal from the sensor 40d received by the reception unit 11.

When the measurement value acquisition unit 13d acquires a determination result indicating that the device 4 and the measurement unit 14d are ready to start measurement from the state determination unit 12d, the measurement value acquisition unit 13d starts measuring the body weight of the measurement unit 14d. Send instructions to do.

The measuring unit 14d starts measuring the weight of the user 50 in response to an instruction to start measuring the weight from the measured value acquiring unit 13d. The measured value indicating the weight of the user 50 is transmitted from the measurement unit 14d to the measurement value acquisition unit 13d.

[Embodiment 4]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

A process in which the weight scale 100 including the plurality of devices 4 such as the sphygmograph 4p in addition to the blood pressure monitor 4a measures the weight of the user 50 will be described with reference to FIGS. FIG. 5 is an image diagram illustrating an example of timing when the weight scale 100 illustrated in FIG. 1 measures the weight of the user 50. FIG. 6 is a flowchart showing the flow of processing until the weight scale 100 measures the weight at the timing shown in FIG. 5 and displays the result.

First, when it is detected that the user 50 is seated (sitting) on the seat surface 101 at time t0 shown in FIG. 5 (YES in S1 of FIG. 6), it is shown in FIG. 5 after a predetermined time (such as 10 seconds) has elapsed. At time t1, guidance Ga is output so that the arm is passed through the pressurizing part of the sphygmomanometer 4a (S2 in FIG. 6). As described above, this guidance may be output as sound from a speaker (not shown) included in the scale 100, or may be characters and images displayed on the display device 20.

When the user 50 passes his arm through the pressurization unit of the sphygmomanometer 4a according to the guidance Ga, the weight scale 100 indicates that the arm of the user 50 is passed through the pressurization unit from the sensor 40 and measurement preparation is completed. A sensor signal is received (corresponding to S3 in FIG. 6).

At time t2 in FIG. 5, weight scale 100 receives a sensor signal indicating that blood pressure monitor 4a is ready for measurement from sensor 40 of blood pressure monitor 4a (YES in S4 (detection step) in FIG. 6). Next, the weight scale 100 outputs the guidance Gp at time t3 in FIG. 5 so that the fingertip is brought into contact with the measurement unit of the pulse wave meter 4p after a predetermined time (such as 5 seconds) has elapsed (FIG. 6). S2a). As shown in FIG. 5, the guidance is not limited to the sphygmomanometer 4a and the pulse wave meter 4p, and guidance for other devices 4 may be presented to the user 50 in order. If the method of use is simple and guidance is not required, these guidances may simply be “Please prepare (name of device 4)”.

When the user 50 touches the sphygmograph 4p according to the guidance Gp, the receiving unit 11 of the scale 100 sets the finger of the user 50 to the sphygmograph 4p from the sensor 40 of the sphygmograph 4p, and prepares for measurement. A sensor signal indicating completion is received (corresponding to S3a in FIG. 6).

At time t5 in FIG. 5, the weight scale 100 receives a sensor signal indicating that the pulse wave meter 4p is ready for measurement from the sensor 40 of the pulse wave meter 4p (in S4a (detection step) in FIG. 6). YES), a weight measurement result is acquired from the measurement unit 14 (S5 in FIG. 6: weight measurement step). The result of the weight measurement is displayed on the display device 20 (S6 in FIG. 6).

Measurement of biological information by the device 4 such as measurement of blood pressure by the sphygmomanometer 4a and measurement of pulse wave by the sphygmomanometer 4p starts simultaneously when all the devices 4 used by the user 50 are ready for measurement. Alternatively, after all the devices 4 used by the user 50 have completed measurement preparation, they may start in sequence after receiving an instruction to start measurement from the scale 100. However, if it is not appropriate to measure simultaneously, such as a sphygmomanometer 4a and a pulse wave meter 4p, which are measurements of the same vascular system, it is desirable to shift the measurement time appropriately. Here, although the example in which the measurement preparation completion of the sphygmomanometer 4a is first performed has been described, the order of the biological measurement by the device 4, the order of completing the measurement preparation, and the like may be arbitrarily set.

As described above, the weight scale 100 measures the body weight by using the preparation state of all the devices 4 used by the user 50 as a trigger to complete the measurement preparation, so that the user 50 can rest at a timing. You can measure your weight. Therefore, the body weight can be measured without any measurement error due to shaking at the time of measurement. In the case of the device 4 that does not cause the user 50 to operate among the devices 4 used by the user 50, for example, a face recognition sensor that uses imaging by the camera 107 does not use the measurement preparation completion as a trigger. Also good.

The scale 100 according to the present invention includes one or a plurality of various devices 4 (for example, a sphygmomanometer 4a, a pulse wave meter 4p, etc.) for measuring the biological information of the user 50. Each device 4 is equipped with a sensor 40 (such as an optical sensor or a pressure sensor). This sensor 40 detects a measurement preparation state for each device 4 (a state in which the user 50 is sitting on the seating surface 101 and an arm and a finger are detected by the sensor 40 included in each device 4). The weight scale 100 starts measurement by all the devices 4 and measurement of body weight all at once, triggered by confirmation that all the devices 4 or the predetermined devices 4 are in the measurement preparation state.

The weight scale 100 determines that the posture of the user 50 is stable by acquiring the measurement preparation state of each device 4 from the sensor 40. It is possible to measure the weight in a state where the measurement preparation states of all the devices 4 are quiet, and it is possible to measure an accurate weight without variations and errors (or little).

[Embodiment 5]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

First, the configuration of the weight scale 100a according to the present embodiment will be described with reference to FIG. FIG. 7 is a block diagram showing an example of a main part configuration of a weight scale 100a according to Embodiment 5 of the present invention. The scale 100a obtains information indicating that the measurement of the biological information by the device 4 has been completed from the device 4, and issues an announcement notifying the user 50 that the measurement of the biological information has been completed. 1 different from the scale 100.

The receiving unit 11 of the scale 100a receives that the measurement by each device 4 has been completed. The reception unit 11 outputs the measurement end information received from each device 4 to the state determination unit 12.

The measurement value acquisition unit 13 acquires the measurement value of the body weight from the measurement unit 14 at a predetermined timing based on the measurement completion status of each device 4 acquired by the state determination unit 12 and outputs the measurement value to the display device 20.

The receiving unit 11 of the weight scale 100a may receive the measurement value measured by the device 4 together with information indicating that the measurement by the device 4 is completed. The measurement value acquisition unit 13 may be configured to acquire a measurement value obtained by the device 4 from the reception unit 11 (not shown) and output the measurement value to the display device 20.

The announcement output control unit (first notification unit, notification control unit) 15 determines that the measurement of the biological information of the user 50 measured by the device 4 is completed when the measurement of the weight by the weight scale 100a is completed. It judges and controls the announcement output part 85, and outputs the announcement which notifies the user 50 of measurement completion. In other words, the announcement output control unit 15 waits to notify the user 50 that the measurement has been completed in any of the devices 4 until the measurement by the scale 100 is completed.

The announcement output unit 85 is not limited to this, but, for example, a speaker (output of an announcement by voice), a display device 20 (output of an announcement by displaying a character string, etc.), a lighting device (lighted or flashed) For example, an output of an announcement by giving a dynamic stimulus to the shoulder and waist of the user 50), and the like. Further, the announcement output unit 85 may be used to output guidance for each device 4 based on an instruction from the announcement output control unit 15.

When the measurement of each device 4 is individually notified to the user 50 of the measurement end, the user 50 performs an end correspondence (cancellation of the mounted state) for each device 4 for which the measurement has been completed. May become stable. For example, when measuring the weight after the measurement of the sphygmomanometer 4a is completed, if the user 50 is notified when the measurement of the sphygmomanometer 4a is completed, the user 50 removes the arm from the pressurizing unit. Therefore, it is impossible to measure the exact weight. Therefore, the weight scale 100a waits to notify the user 50 that the measurement is finished in any of the devices 4 until the measurement of the weight is finished, and the measurement is finished after the weight measurement is finished. Is notified to the user 50. Thereby, it is possible to prevent the posture of the user 50 from becoming unstable during the weight measurement.

Further, the announcement output control unit 15 waits to notify the user 50 that the measurement is finished in any of the devices 4 until the measurement of the weight is finished, but after the measurement of the weight is finished, You may make it notify the user 50 that the measurement in each apparatus 4 was complete | finished. Thereby, it is possible to prevent the posture of the user 50 from becoming unstable during the weight measurement. In one modification, the user 50 may be notified of the measurement after all the devices 4 and the weight scale 100a have been measured. Thereby, it is possible to prevent the posture of the user 50 from becoming unstable not only during the measurement of the weight but also during the measurement of each device 4.

FIG. 8 illustrates the case where the weight is measured after the measurement by all the devices 4 is finished as an example, but is not limited thereto. For example, the weight may be measured after the measurement of the device 4 (for example, the sphygmomanometer 4a) is completed, and then the measurement of another device 4 (for example, the pulse wave meter 4p) may be started. Further, a plurality of devices 4 may be measured simultaneously, or the weight scale 100a and the device 4 may be measured simultaneously.

(Weight measurement with weight scale 100a)
Next, a process in which the weight scale 100a including the plurality of devices 4 such as the sphygmomanometer 4a and the pulse wave meter 4p measures the weight of the user 50 will be described with reference to FIGS. FIG. 8 is an image diagram illustrating an example of timing at which the weight scale 100a illustrated in FIG. 7 measures the weight of the user 50. FIG. 9 is a flowchart showing the flow of processing from the time when the weight scale 100a measures the weight at the timing shown in FIG. 8 until the end of measurement is announced.

First, when it is detected that the user 50 is seated (sitting) on the seat surface 101 at time t0 shown in FIG. 8 (YES in S1 of FIG. 9), it is shown in FIG. 8 after a predetermined time (such as 10 seconds) has elapsed. At time t1, guidance Ga is output so that the arm is passed through the pressurizing part of the sphygmomanometer 4a (S2 in FIG. 9).

When the user 50 passes his arm through the pressurization unit of the sphygmomanometer 4a according to the guidance Ga, the sensor 40 sends a sensor signal indicating that the arm of the user 50 is passed through the pressurization unit and measurement preparation is complete to the weighing scale 100a. (Corresponding to S3 in FIG. 9).

The weight scale 100a receives a sensor signal indicating that the sphygmomanometer 4a is ready for measurement from the sensor 40 of the sphygmomanometer 4a at time t2 in FIG. 8 (YES in S4 (detection step) in FIG. 9). .

The sphygmomanometer 4a measures blood pressure after completing measurement preparation. When the blood pressure measurement is completed, the receiving unit 11 of the weight scale 100a receives information indicating that the blood pressure measurement by the blood pressure monitor 4a is completed.

When the receiving unit 11 of the weight scale 100a receives information indicating that the measurement by the sphygmomanometer 4a has been completed (S11 in FIG. 9), the weight scale 100a next detects the pulse after a predetermined time (such as 5 seconds) has elapsed. Guidance Gp is output at time t3 in FIG. 8 so that the fingertip is brought into contact with the measurement unit of wavemeter 4p (S2a in FIG. 9).

When the user 50 brings the fingertip into contact with the sphygmograph 4p according to the guidance Gp, the sensor 40 of the sphygmograph 4p is set to a sensor signal indicating that the finger of the user 50 is set on the sphygmograph 4p and measurement preparation is complete. Is transmitted to the scale 100a (corresponding to S3a in FIG. 9).

When the user 50 sets his / her finger on the sphygmograph 4p according to the guidance Gp, the weight scale 100a indicates that the user's 50 finger is in contact with the measurement unit of the sphygmograph 4p from the sensor 40 and the measurement preparation is completed. Is received (corresponding to S3a in FIG. 9).

The weight scale 100a receives a sensor signal indicating that the pulse wave meter 4p is ready for measurement from the sensor 40 of the pulse wave meter 4p at time t4 in FIG. 8 (in S4a (detection step) in FIG. 9). YES).

When the receiving unit 11 receives information indicating that the measurement of the pulse wave meter 4p is completed (S11a in FIG. 9), the weight scale 100a then causes the measurement value acquiring unit 13 to measure the measuring unit at time t5 in FIG. The weight measurement result is acquired from 14, and the measurement ends at t6 (S5 in FIG. 9: weight measurement step).

When the measurement of the biological information and the measurement of the body weight by the device 4 are all completed (YES in S12 in FIG. 9), the announcement output control unit 15 performs the weight scale 100a, the sphygmomanometer 4a, and the pulse wave meter at time t7 in FIG. Announcement A1 for notifying the user 50 that the 4p measurement is completed is output from the announcement output unit 85 (S13 in FIG. 9).

The user who has been notified of this announcement A1 performs an end response such as removal of the device 4 (cancellation of the wearing state), but there is no problem because the weight measurement has already ended at this time.

In addition, although the case where the measurement by the devices 4 such as the blood pressure monitor 4a and the pulse wave system 4p is sequentially performed is described here as an example, the preparation is started all at once and the measurement is sequentially started from the ready devices 4 Alternatively, the measurement may be performed all at once. Moreover, although the case where the measurement of the weight scale 100a is performed after the measurement of the equipment 4 is described as an example, the measurement of the equipment 4 and the weight scale 100a are performed simultaneously after the measurement of all the equipment 4 is completed. The structure which performs a measurement may be sufficient. Thereby, measurement of biological information can be performed in a short time. However, as described above, when measuring biological information that is not desired to be measured simultaneously, the measurement time is appropriately shifted from each other.

In addition, here, the example in which the measurement preparation of the sphygmomanometer 4a is first completed has been described, but the order of the biological measurement by the device 4, the order of completing the measurement preparation, and the like may be arbitrarily set. However, it is desirable to measure the weight after the biological information is measured by some device 4. Thereby, the stable weight measurement can be performed using the fact that the user 50 is at rest during the measurement by the device 4.

[Embodiment 6]
The following will describe another embodiment of the present invention with reference to FIG. 10 and FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

The weight scale 100b according to the present embodiment outputs the announcement that guides the user 50 to complete the measurement preparation for the device 4 that is not correctly prepared for measurement, with the above-described weight scales 100 and 100a. Is different.

Note that the measurement preparation is not correct means that the preparation on the user 50 side for starting the measurement in the device 4 is insufficient or inappropriate. When it is necessary to place a predetermined part of the body of the user 50 at the position in order to start the measurement in the device 4, there may be a situation where the predetermined part is shifted from the predetermined position.

First, the configuration of the weight scale 100b according to the present embodiment will be described with reference to FIG. FIG. 10 is a block diagram illustrating an example of a main configuration of a weight scale 100b according to Embodiment 6 of the present invention. When it is determined that the measurement preparation of the device 4 is not correctly performed, the weight scale 100b issues an announcement for guiding the user 50 to complete the measurement preparation of the device 4 in the weight of FIG. It is different from a total of 100.

The state determination unit (measurement end determination unit) 12 determines whether or not the device 4 is ready to start measurement based on the sensor signal from the sensor 40 received by the reception unit 11. If the measurement by the device 4 can be started, the determination result is output to the measurement value acquisition unit 13. On the other hand, if it is determined that the measurement by the device 4 is not ready to start, the determination result is output to the announcement output control unit 15.

When the announcement output control unit (second notification unit) 15 obtains a determination result indicating that the measurement preparation of the device 4 is not completed from the state determination unit 12, the announcement output control unit (second notification unit) 15 controls the announcement output unit 85 to inform the user 50. On the other hand, an announcement for notifying that the device 4 cannot start measurement is output.

This announcement may be a specific one related to the device 4 such as “please put your arms (fingertips) a little deeper”, or something related to general measurement of biological information such as “please rest”. It may be.

(Weight measurement with weight scale 100b)
Next, a process in which the weight scale 100b including the blood pressure monitor 4a as the device 4 measures the weight of the user 50 will be described with reference to FIG. FIG. 11 is an image diagram illustrating an example of timing at which the weight scale 100b illustrated in FIG. 10 measures the weight of the user 50.

When it is detected that the user 50 is seated (sitting) on the seat surface 101 at time t0 shown in FIG. 11, the pressurization unit of the sphygmomanometer 4a is displayed at time t1 shown in FIG. 11 after a predetermined time (10 seconds or the like) has elapsed. Guidance Ga is output so that the arm is passed through.

For example, if the user 50 puts his arm through the pressurizing part of the sphygmomanometer 4a according to the guidance Ga, but the way of passing the arm is shallow and not inserted sufficiently deeply, accurate blood pressure measurement cannot be performed (that is, measurement) Not ready). As described above, the weight scale 100b that has received the sensor signal indicating that the measurement preparation is not correctly performed from the sensor 40 outputs an announcement A2 notifying that the measurement of the sphygmomanometer 4a cannot be started to the user 50. . The announcement A2 starts from a time t2b after a predetermined time (for example, 5 seconds) has elapsed from the time t2a at which the sensor signal that has detected that the measurement preparation is incomplete is received.

At time t5, when the user 50 improves the state of the arm set on the sphygmomanometer 4a according to the announcement A2, the sensor 40 transmits a sensor signal indicating that the measurement preparation of the sphygmomanometer 4a is completed.

In the weight scale 100b that has received the sensor signal indicating that the preparation for measurement by the sphygmomanometer 4a is completed from the sensor 40, the measurement value acquisition unit 13 acquires the weight measurement result from the measurement unit 14 at time t5 in FIG. The weight measurement result is displayed on the display device 20.

The scale 100b measures the weight of the user 50 after guiding the user 50 to correct the usage state of the device 4 that is not in a state where measurement of biological information can be started. Thereby, it is possible to wait for the usage status of the device 4 to be corrected and then measure the weight.

[Embodiment 7]
The following will describe another embodiment of the present invention with reference to FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

It is conceivable that the user 50 does not use all the devices 4 or it is difficult to use some of the devices 4. In that case, even if guidance Ga is output, the measurement preparation of all the devices 4 is not completed. Therefore, the weight scale 100b is configured so that only the device 4 that is currently ready is provided if there is no new device 4 that is ready for preparation even after the guidance Ga is output and the predetermined time T (predetermined time) has elapsed. Is used by the user 50 and the measurement preparation of the device 4 is completed.

When it is detected that the user 50 is seated (sitting) on the seat surface 101 at time t0 shown in FIG. 12, the pressurizing unit of the sphygmomanometer 4a is displayed at time t1 shown in FIG. 12 after a predetermined time (10 seconds or the like) has elapsed. Guidance Ga is output so that the arm is passed through.

The weight scale 100b that has received the sensor signal indicating that the measurement preparation of the sphygmomanometer 4a is not correctly performed from the sensor 40 outputs an announcement A2 notifying that the measurement of the sphygmomanometer 4a cannot be started to the user 50. . The announcement A2 starts from a time t2b after a predetermined time (for example, 5 seconds) has elapsed from the time t2a at which the sensor signal that has detected that the measurement preparation is incomplete is received.

If the user 50 does not prepare for measurement of the sphygmomanometer 4a after time t2b, the measurement value acquisition unit 13 at time t5 causes the measurement value acquisition unit 13 to have a fixed time T (for example, 30 seconds or 1 minute) after the time t2b. A weight measurement result is acquired from the measurement unit 14, and the weight measurement result is displayed on the display device 20. It should be noted that blood pressure is not measured by the sphygmomanometer 4a even when a certain time T has elapsed since the announcement A2 was output. When the arm of the user 50 who uses the sphygmomanometer 4a is not correctly inserted into the pressurizing part of the sphygmomanometer 4a, it is not possible to apply appropriate pressure, and there is a risk of excessive pressurization. Therefore, it is desirable to measure only the body weight without starting the blood pressure measurement after a certain time T has elapsed since the announcement A2 was output. When a certain time T has elapsed since the announcement A2 was output, the user may recognize that the arm has been correctly inserted into the sphygmomanometer 4a and misunderstand that the announcement A2 is an error. There is sex. In this case, since the user 50 assumes that blood pressure can be measured, the posture is rested and accurate weight measurement is possible.

As described above, the weight scale 100b newly outputs the announcement A2 notifying the user 50 that the preparation on the user 50 side is not properly made for a certain time T (for example, 0.5 to 1 minute). If a signal indicating that measurement preparation is complete is not received, it is determined that instrument preparation is complete, and the weight is measured.

In addition, in the weight scale 100b having a plurality of devices 4 including the sphygmomanometer 4a (pulse wave meter 4p, etc.), a certain time T has elapsed since the announcement A2 notifying that the measurement preparation of the sphygmomanometer 4a is not made correctly is output. After elapse of time, measurement by the device 4 other than the blood pressure monitor 4a may be started. However, it is desirable that the device 4 other than the sphygmomanometer 4a is limited to a case where no force is applied to the body of the user 50 like the pressurizing unit of the sphygmomanometer 4a.

[Modification]
The above-described weight scales 100a and 100b use the output of the announcement after measurement of biological information and body weight or before the measurement preparation of the device 4 is completed. However, the configuration is not limited to this, and the announcement may be used during measurement of biological information and body weight.

The announcement in this case can be expected to be effective in maintaining the resting state of the user 50, unlike the announcements A1 and A2. For example, the announcement may be a character string or voice that clearly notifies the user 50 that the measurement is currently being performed, and actively seeks to maintain a stable state. In addition to or in combination with this announcement, content such as video or music that is expected to have an effect of resting the mind and body of the user 50 may be reproduced.

As shown in FIG. 7, when receiving information indicating that measurement is in progress from the device 4, for example, information that is after the start of measurement and before the end of measurement, the state determination unit 12 performs measurement by the device 4. Judge that it is currently being measured. When the announcement output control unit (third notification unit, playback unit) 15 acquires the determination result of the state determination unit 12, the announcement output control unit 15 outputs a predetermined sound, video, music, or the like that is output during measurement by the device 4. Output from the unit 85.

Thus, it is possible to assist the user 50 in resting even during measurement of the biological information of the user 50. Therefore, the weight of the user 50 can be accurately measured.

[Example of software implementation]
The control blocks (particularly the state determination unit 12, the measurement value acquisition unit 13, and the announcement output control unit 15) of the weight scales 100, 100a, and 100b are logic circuits (hardware) formed in an integrated circuit (IC chip) or the like. It may be realized by software, or may be realized by software using a CPU (Central Processing Unit).

In the latter case, the weight scales 100, 100a, and 100b include a CPU that executes instructions of a program that is software that realizes each function, and a ROM (in which the program and various data are recorded so as to be readable by a computer (or CPU)). A Read Only Memory) or a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.
