Hereinafter, an embodiment for carrying out the present disclosure with reference to the drawings will be described. The following embodiments are examples for explaining the present disclosure, and the technical scope of the invention described in the claims is not limited to the following description.

A general sensor device is a device that can acquire information of a subject including biological information such as blood pressure and pulse. Here, the subject is a subject whose biological information is measured and body movement is detected, and refers to, for example, a patient, a person being assisted, or the like. In addition, the target person may include a healthy person, regardless of age or gender.

For such a device, for example, in the case of blood pressure, it is necessary to attach a sphygmomanometer to the subject, and in the case of body temperature, a separate device is used for each biological information to be measured, such as using a thermometer. I had to measure.

Such a device needs to individually measure information such as blood pressure, body temperature, and blood glucose level, which may be troublesome for the subject. In addition, such a device cannot continuously measure the information of the subject. If such a device continuously acquires the subject's information, the subject needs to be at rest. In addition, it is necessary to provide multiple sensors as a device, resulting in a large device or the need to install separate devices, which may be convenient for users such as staff. be.

Here, the staff means those who work in hospitals and facilities. For example, the staff refers to medical workers such as doctors and nurses, facility workers such as caregivers working at the facility, and includes domestic caregivers such as family members and visiting service staff. These persons are called staff, etc.

In recent years, wearable terminal devices such as so-called smart watches have appeared as sensor devices. However, when the staff and others tried to measure the target person correctly using a smart watch, the measurement posture was limited and it was difficult to measure continuously. In particular, the tendency was remarkable when measuring the blood pressure of the subject, the electrocardiogram, and the like.

In addition, it is difficult for conventional smart watches to be used in medical institutions, long-term care facilities, etc. because the information that can be acquired is limited. In particular, if a conventional smartwatch is used and customized for each subject, the device itself becomes expensive, and it is not realistic to use it for inpatients or all the subjects in the facility.

In addition, smart watches consume a lot of power and often have to be charged each time, so it was not easy to use.

A sensor device or the like for solving such a problem will be described below based on a detailed embodiment. The following embodiments are examples of the present disclosure, and the invention is not limited to the contents thereof.

For example, the unit acquires information such as an electric signal, vibration, and acceleration of a subject. The unit consists of one or more devices. The device may be the same as the unit, or it may simply be an electrode that acquires the subject's electrical signal. Hereinafter, the unit will be described.

[2.1 Paste type]
FIG. 2 is a diagram schematically showing the configuration of the sensor device 20A. The sensor device 20A of FIG. 2 is an example showing a case where the target person is fixed to the human body with an adhesive member (for example, a skin-attached double-sided tape). The sensor device 20A is attached to any part of the human body of the subject (for example, any part such as the chest, arms, fingertips, or feet).

The sensor device 20A is composed of one or a plurality of units. The sensor device 20A shown in FIG. 2 has a first unit 210 and a second unit 220. The first unit 210 is directly or indirectly attached to the human body by the adhesive member 230. The adhesive member 230 uses an adhesive that has no effect even when attached to the human body, and for example, a silicone-based adhesive according to ISO-10993 is used.

Here, the unit constituting the sensor device 20A includes a substrate. For example, the first unit 210 includes a first substrate 212, and the second unit 220 includes a second substrate 222.

The board is equipped with a configuration such as a sensor for acquiring information of the target person, a controller (control unit) for controlling the sensor, and a power supply unit. Details of the configuration included in the substrate will be described later.

Here, each unit has one or more connections. For example, the first unit 210 has a connecting portion 214. Further, the second unit 220 has a connection portion 224. The connection portion 214 is located at the position of a recess in the first unit 210 in FIG. 2. Further, the connection portion 224 is located at the position of the convex portion of the second unit 220 in FIG.

The connection portion 214 is, for example, a contact provided on the first substrate 212. Further, the connection portion 224 is, for example, a contact provided on the second substrate 222. When the connection portion 224 is connected to the connection portion 214 (that is, the contacts provided in each connection portion come into contact with each other), the first substrate 212 and the second substrate 222 are conductive.

That is, in the first unit 210 and the second unit 220, the power line and the signal line are connected by connecting the connecting portion 214 and the connecting portion 224, and they are electrically connected.

Here, the connection portion 214 is a contact (electrode) on which signals and electricity flow on the first substrate 212. In FIG. 2, the connecting portion 214 is arranged in a part or the whole of the recess (dent) of the first unit 210.

Further, the second unit 220, which is the upper unit, has one or a plurality of convex portions (convex contacts) as the connecting portion 224 on one side (second surface).

By placing the second surface side of the second unit 220 on the first surface side of the first unit 210 and bringing the convex portion of the second unit 220 into contact with the contact of the first unit, the first unit The 210 can exchange data with the second unit 220.

Further, by adopting a conductive urethane, a spring contact, or the like for the convex portion (connecting portion 224), a reliable contact may be secured. Further, the convex portion (connecting portion 224) may be further coated with the conductive urethane if the resistance of the conductive urethane is high.

Here, the method of connecting the first unit 210 and the second unit 220 can be considered as follows.

(1) Adhesive (double-sided adhesive)
By applying a double-sided adhesive between each unit, multiple units are connected by adhesive force. For example, a conductive double-sided adhesive may be applied in advance to the connecting surfaces of the connecting portion 224 and the connecting portion 214. The double-sided adhesive may be applied each time, or an adhesive that is easily peeled off may be used. Each unit is connected by an adhesive.

Further, an adhesive may be applied to the surface where the first unit 210 and the second unit 220 are in contact with each other. For example, an adhesive may be applied to the first surface side of the housing of the first unit 210 and / or an adhesive may be applied to the second surface side of the housing of the second unit 220.

(2) Magnet A magnet is built in each unit, and multiple units are connected by magnetic force. For example, a magnet is provided at a predetermined position of the first unit 210, and a magnet is provided at a position facing the second unit 220. It suffices to have one or more magnets. When connecting each unit with a magnet, the connecting portion does not have to have an uneven shape, and may have a connecting portion that can be electrically connected.

(3) Fastener A fastener may be attached to each unit. For example, a fastener is provided between the first unit 210 and the second unit 220, and the fasteners are used to connect the respective units.
(4) Housing fitting Each unit may be provided with a hook shape or a press-fitting shape. Then, each unit is connected by fitting the unit.

(5) Dressing material (medical tape)
The entire unit may be covered with a dressing material while the units are stacked and placed on the skin of the subject.

Further, as a method of connecting each unit, a method of using a connecting member may be used. When using a connecting member, the two units may have the same shape. Further, three or more units to be connected may be connected.

FIG. 3 is a diagram schematically showing a case where each unit is connected by using a connecting member. In FIG. 3A, a connecting member 226 is used between the first unit 210 and the second unit 220. The connecting member 226 has a convex connecting portion 226A and a connecting portion 226B. The connecting portions 226A and the connecting portions 226B arranged above and below are electrically connected to each other. For example, in FIG. 3A, the connection portion 226A arranged on the left side and the connection portion 226B are electrically connected.

The connecting portion 214 of the first unit 210 and the tip of the connecting portion 226A of the connecting member 226 come into contact with each other. Further, the connection portion 224 of the second unit 220 and the tip of the connection portion 226B come into contact with each other. As a result, the first unit 210 and the second unit 220 are electrically connected via the connecting member 226. The first unit 210 and the second unit 220 in FIG. 3A have the same shape.

Further, the third substrate 242 and the second substrate 222 are electrically connected via the connecting member 226. That is, the first unit 210, the second unit 220, and the third unit 240 are connected, respectively.

[2.2 Electrode type]
A case where the basic unit to be attached to the subject is a device including an electrode type will be described with reference to FIGS. 4 and 5. FIG. 4A is a top view schematically showing the sensor device 20D which is the first unit 270 including the first device 250 and the second device 260.

FIG. 4A shows a first device 250 and a second device 260. Here, the first device 250 is an electrode attached to the human body and can detect the potential. Here, as the electrode attached to the human body, for example, a nanomesh electrode sheet can be used.

Here, the nanomesh electrode is an electrode made of a highly biocompatible metal (for example, gold) and a polymer material (for example, polyvinyl alcohol) arranged in a nano-sized mesh structure. Compared to electrodes that are attached to the human body using conventional films or rubber sheets, nanomesh electrodes allow the wearer to breathe through the skin and cause less discomfort when worn.

Further, the first device 250 has a connection portion 252. The connection portion 252 is, for example, a magnet. The second device 260 is magnetically connected to a connecting portion 262 made of a magnet. As a result, the first device 250 functions as an electrode (sensor) of the first unit 270.

The connection portion connecting the first device 250 and the second device 260 may have another configuration. For example, in FIG. 4A, the first device 250 and the second device 260 each have a magnet, but a configuration may be provided in which only one of them is provided. For example, the connecting portion may be a member having a magnet on one side and a magnet such as iron on the other side. In addition, the connection portion can be connected to the correct position by using magnets on both sides, and it is possible to prevent erroneous combination.

Here, the second device 260 has a module 264. The module 264 includes, for example, a controller (control unit), a power supply unit, a communication unit, and a storage unit, if necessary.

Further, the second device 260 can acquire an electric signal from the electrodes of the first device 250. In this, the entire first device 250 is an electrode (electrode sheet), and the second device 260 can acquire an electric signal by electrically connecting to the electrode.

Further, the first device 250 and the second device 260 may be connected by a configuration other than the magnet. For example, a double-sided tape may be attached to the second device 260 and connected to the first device 250, or the entire surface may be covered with a dressing material (medical tape).

As shown in FIG. 4A, the first device 250 does not have to have a configuration such as a control unit. The first device 250 may have the function of an RFID tag.

4 (b) to 5 (b) are diagrams for explaining different configurations of the units. For example, in the first unit 275 (sensor device 20E) of FIG. 4B, the first device 250 and the second device 260 are connected by a plurality of magnets. For example, the first device 250 is provided with one or more magnet connection portions 252, and the second device 260 is provided with one or more magnet connection portions 262. It is preferable that the number of magnets provided in the first device 250 and the second device 260 is the same. Further, the positions of the magnets provided in the first device 250 and the second device 260 are preferably opposite positions.

Further, as shown in FIG. 4B, the first unit 275 (sensor device 20E) may connect the first device 250 and the second device 260 via the connecting member 226. For example, the end of the connection portion 224 provided on the connection member 226 connects to the connection terminal provided on the first device 250 or the connection terminal provided on the second device 260. As a result, the first device 250 and the second device 260 are electrically connected.

Here, the second device 260 has a function as a unit as a single unit. Therefore, the second device 260 can be changed from the information of the target person according to the type of the information of the target person that the staff or the like wants to acquire.

That is, in the first unit 275, the first device 250 is attached to the human body of the subject, and the second device 260 can be replaced. As a result, the first unit 275 can select and attach the second device 260 that outputs the information to be acquired.

Further, as shown in FIG. 5, a different unit may be provided. In the sensor device 20F of FIG. 5A, the second unit 280 is connected to the side of the first unit 275. For example, in the second unit 280, for example, a connection portion 284 composed of a connector is provided near the connection portion of the first unit 275 (second device 260) (for example, in FIG. 5A, the right end portion of the device). ). The second unit 280 is connected to the second device 260 of the first unit 275 via the connector. As a result, the second unit 280 can be connected to the first device 250, and the sensor 282 mounted on the second unit 280 can be used.

Further, the sensor device 20G of FIG. 5B connects the unit to be added to the lower part of the first unit 275 (second device 260). That is, a connector is provided at the bottom of the second device 260. For example, the second unit 290 connects a connection portion 294 composed of a connector, for example, to the lower part of the first unit 275 (second device 260). The second unit 290 is connected to the second device 260 via the connector. The second unit 290 can be connected to the first device 250, and the sensor 292 mounted on the second unit 290 can be used.

In addition, as shown in FIG. 3B, the unit to be added may be added vertically. Further, as shown in FIG. 3B, after adding the units to be added vertically, the units may be added horizontally as shown in FIG. 5A. That is, the configurations of FIGS. 3 to 5 can be arbitrarily combined. This also applies to the paste type described in 2.1.

[3. Function configuration]
[3.1 System configuration]
The configuration required for the system 1 in the present embodiment will be described with reference to FIG. The system 1 includes a control device 1000 for controlling the system 1, a sensor device 2000 for acquiring information on the target person and information on the environment, and an external device 3000.

(3) Temperature sensor, humidity sensor, barometric pressure sensor, illuminance sensor, ultraviolet sensor The sensor device 2000 may acquire not only the information of the target person but also the information of the environment in which the target person is (environmental information). Here, the environment is information about the surroundings of the subject, and includes, for example, the environment of the living room / hospital room and the environment around the subject.

For example, when the sensor device 2000 uses a temperature sensor, the information acquisition unit 1106 can acquire the temperature as environmental information. This temperature is, for example, the temperature of the subject's living room / hospital room. Further, when the sensor device 2000 uses a humidity sensor, the information acquisition unit 1106 can acquire humidity as environmental information. This humidity is, for example, the humidity of the subject's living room / hospital room.

Further, when the sensor device 2000 uses the illuminance sensor, the information acquisition unit 1106 can acquire the illuminance as environmental information. Further, when the sensor device 2000 uses an ultraviolet sensor, the information acquisition unit 1106 can acquire the amount of ultraviolet rays as environmental information.

(4) Acquisition from other than the sensor device 2000 For example, the information acquisition unit 1106 may acquire information regarding the attributes of the target person from other than the sensor device 2000. The attributes of the target person may be input from the operation unit 1300 of the control device 1000, or may be acquired from the information of the target person from the electronic medical record stored in the electronic medical record server via the communication unit 1500. For example, the determination unit 1102 may determine the state of the target person based on the information regarding the attributes of the target person from other than the sensor device 2000 and the information of the target person acquired from the sensor device 2000.

For example, the information acquisition unit 1106 can acquire age, gender, and weight as individual attributes of the subject. In addition, the information acquisition unit 1106 can acquire diseases and symptoms as medical information of the subject. In addition, the information acquisition unit 1106 can acquire physical ability, cognitive ability, family situation, and economic situation as living information of the subject.

The storage unit 1200 stores various information and programs. For example, the storage unit 1200 stores information about the target person in the target person information storage area 1202. Here, the information about the subject (subject information) may include blood pressure, SpO2, pulse rate, body temperature, electrocardiogram, myoelectricity, skin surface resistance, posture / motion, and the like.

In addition, the subject information may include acetone, acetaldehyde, acetic acid, ammonia, diacetyl, 2-nonenal, pH, water content, amount of germs, surface reactivity and the like.

The storage unit 1200 stores information about the environment in the environment information storage area 1204. Here, the information about the environment (environmental information) may include temperature (air temperature), humidity, atmospheric pressure, illuminance, amount of ultraviolet rays, and the like.

The storage unit 1200 stores information about the attributes of the target person in the attribute information storage area 1206. Here, the information regarding the attribute (attribute information) may include the name, age, gender, weight, etc. as the individual attribute of the subject. In addition, the attribute information may include medical information and living information of the subject.

The medical information may include information on the subject's disease, illness, or symptom. In addition, the living information may include the physical ability, cognitive ability, family situation, economic situation, etc. of the subject.

The operation unit 1300 operates the control device 1000. For example, the operation unit 1300 is realized by a hardware switch using an operation button or a software switch using a touch panel. Further, the operation unit 1300 may be realized by an operation device different from the control device 1000 such as a keyboard and a mouse, or may be realized by voice operation.

The display unit 1400 can provide information to the target person, staff, and the like. For example, the display unit 1400 may be realized by a liquid crystal display or an organic EL panel.

The communication unit 1500 provides an interface for the control device 1000 to communicate with other devices. The communication unit 1500 communicates with the sensor device 2000, the external device 3000, and other devices regardless of whether they are wired or wireless.

The notification unit 1450 notifies the target person, staff, and the like. The notification unit 1450 may be realized by, for example, a speaker capable of outputting sound or voice, a vibration device that gives vibration, or a light emitting device that performs notification by light emission.

The communication unit 1500 may be realized by, for example, a communication module capable of connecting by USB, a communication module capable of LAN communication such as a wired / wireless LAN, and a communication module using mobile communication such as LTE / 4G / 5G.

In addition, each configuration provided in the above-mentioned control device 1000 may use another device or a cloud as needed. For example, the display unit 1400 and the notification unit 1450 may be provided in the sensor device 2000.

The sensor device 2000 can acquire information on the target person and information on the environment by being attached to the target person. The sensor device 2000 is composed of one or a plurality of units.

Here, an example of one unit constituting the sensor device 2000 will be described with reference to FIG. 7. The unit 2100 may be provided with one or a plurality of control units 2110, storage units 2120, detection units 2130, communication units 2140, power supply units 2150, and the like on the substrate.
The control unit 2110 is a controller that controls each configuration. Further, the storage unit 2120 stores the acquired signal and various information. Further, the detection unit 2130 can detect an electric signal, an acceleration, a gas component, and the like. That is, the detection unit 2130 can detect various signals and information, so that the entire unit 2100 can function as one sensor.

Here, the unit 2100 may function as any known sensor. For example, the unit 2100 functions as various sensors such as an optical sensor, a temperature sensor, a humidity sensor, a humidification sensor, an angular velocity sensor, a geomagnetic sensor, a pressure sensor, a potential sensor, and an odor sensor.

Further, the detection unit 2130 of the unit 2100 may be an electrode. For example, the detection unit 2130 may be a gel electrode or a nanomesh electrode.

Further, the detection unit 2130 does not have to be a sensor. For example, by mounting an RFID, information that identifies an individual may be stored.

Further, the detection unit 2130 is not generally a sensor, but may be one that can be used as a sensor. For example, the detection unit 2130 may be realized by a camera device, a microphone device, or the like.

Further, the control unit 2110 can communicate with the control device 1000 (control unit 1100) via the communication unit 2140. As a result, the signal detected by the detection unit 2130 and the information processed based on the signal by the control unit 2110 are transmitted to the control device 1000 (control unit 1100).

The communication unit 2140 is a wireless communication (for example, Bluetooth (registered trademark), a wireless LAN using WiFi, mobile communication capable of communicating with LTE / 4G / 5G, NFC, etc.) and another device (for example, a control device). It may be connected to 1000), or it may be connected to another device (for example, control device 1000) by wire communication (for example, USB or the like).

The power supply unit 2150 supplies electric power to each configuration. The power supply unit 2150 supplies electric power to each unit. For example, it may be a primary battery (disposable, effect case) or a secondary battery. Further, it may be a power source for private power generation such as photovoltaic power generation, temperature difference power generation, and operating power generation.
Further, the connection unit 2160 is connected to another unit. As a result, the control unit 2110 can receive signals and information from other units via the connection unit 2160. Further, the control unit 2110 can transmit signals and information to other units via the connection unit 2160.

Further, one or more of these configurations may be mounted on the substrate of the unit. For example, when a plurality of units are connected, the power supply unit 2150 may be provided on the uppermost board, and the power supply unit 2150 is not required for the other units.

This supplies power from the uppermost power supply unit 2150 to the lower unit via the connection unit. By doing so, if a unit including the power supply unit 2150 is added to the uppermost stage, power can be supplied to the configurations of all the units.

Further, in the sensor device 2000, when the power supply unit 2150 cannot supply power to another configuration (that is, the battery runs out, etc.), only the unit on which the power supply unit 2150 is mounted needs to be replaced.

That is, when the unit 2100 functions as a sensor, it suffices to have at least a detection unit 2130 and a connection unit 2160. Further, if it merely supplies power, it suffices to have at least a power supply unit 2150 and a connection unit 2160. Further, it is preferable that the unit 2100 includes a control unit 2110 when the unit itself executes processing or the signal detected by the detection unit 2130 is processed. Further, the connecting portion 2160 is necessary for electrically connecting to another unit, and is preferably provided in the unit 2100.

Further, the unit 2100 may be composed of a plurality of devices. For example, it may be configured by a first device including a detection unit 2130, a connection unit 2160, and a second device having a configuration other than the detection unit 2130. In this case, by exchanging the second device, the unit 2100 can acquire the biometric information corresponding to the second device.

The external device 3000 is various devices that can be connected to the control device 1000. For example, in FIG. 1, the external device 40 corresponds. Further, the external device 3000 may be an electronic medical record server or the like connected to the network NW.

The control device 1000 may acquire the attribute information of the target person from the electronic medical record server. Further, the control device 1000 may acquire environmental information such as temperature and humidity from an external device such as a thermometer or a hygrometer, or may acquire it from a server on the Internet.

In addition, various methods can be considered as a method of acquiring the information of the target person. Specifically, there are a method of acquiring by the sensor device 2000 and a method of acquiring by the information acquisition unit 1106. For example, a case where the information acquisition unit 1106 acquires the heart rate as the information of the subject will be described as an example.

(1) First Method The sensor device 2000 includes a unit capable of calculating a heart rate as a unit 2100. The control unit 2110 of the unit 2100 acquires the heartbeat from the electric signal detected by the detection unit 2130. Then, the control unit 2110 calculates the heart rate (for example, the heart rate per minute) from the acquired heart rate. Then, the control unit 2110 transmits the heart rate to the control device 1000 via the communication unit 2140.

In the control device 1000, the information acquisition unit 1106 acquires the heart rate via the communication unit 1500. The information acquisition unit 1106 stores the heart rate in the storage unit 1200 (target person information storage area 1202) in association with the target person. The information acquisition unit 1106 may store the date and time measured together with the heart rate.

(2) Second Method The sensor device 2000 includes a unit capable of acquiring a heartbeat (beat of a subject) as a unit 2100. The control unit 2110 of the unit 2100 acquires the heartbeat from the electric signal detected by the detection unit 2130. Then, the control unit 2110 transmits a heartbeat signal to the control device 1000 via the communication unit 2140.

In the control device 1000, the information acquisition unit 1106 acquires the heartbeat via the communication unit 1500. Then, the information acquisition unit 1106 calculates the heart rate from the acquired heart rate. The information acquisition unit 1106 stores the calculated heart rate in the storage unit 1200 (target person information storage area 1202) in association with the target person.

(3) Third Method The sensor device 2000 includes a unit capable of acquiring an electric signal as the unit 2100. The control unit 2110 of the unit 2100 transmits information based on the electric signal detected by the detection unit 2130 to the control device 1000 via the communication unit 2140.

In the control device 1000, the information acquisition unit 1106 receives information based on an electric signal via the communication unit 1500. Then, the information acquisition unit 1106 acquires a heart rate from the information based on the electric signal and calculates the heart rate. The information acquisition unit 1106 stores the calculated heart rate in the storage unit 1200 (target person information storage area 1202) in association with the target person.

The information of the subject has been described by taking the heart rate as an example, but other information (for example, respiratory rate, blood pressure, posture of the subject, etc.) is similarly used by either the sensor device 2000 or the control device 1000. I just need to get it.

[3.2 Device configuration]
The configuration of the system 1 described with reference to FIG. 6 may be implemented in any of the devices included in the system 1. For example, a case where the configuration of the control device 1000 is realized by the terminal device 10 and the server device 30 of FIG. 1 will be described with reference to FIGS. 8 and 9 as an example.

The operation unit, display unit, and notification unit may also include the server device 30. Further, since the operation unit is an operation device, the display unit is a display device, and the notification unit is a notification device, it may be configured by an external device.

The information stored in the storage unit 110 of FIG. 8 and the storage unit 310 of FIG. 9 may be stored in only one of the devices. Further, the information may be stored in the cloud, for example.

[4. Processing flow]
[4.1 Main processing]
In the present embodiment, the main processing executed by the system 1 will be described with reference to FIG. In the processes of FIGS. 10 and 11, it is described that the control unit 1100 of the control device 1000 executes the process, but when the terminal device 10 is replaced, the control unit 100 executes the process and is replaced by the server device 30. If so, the control unit 300 executes the process.

The control unit 1100 of the control device 1000 determines whether the target person is already equipped with any of the units (step S100). If none of the units are installed on the target person, the staff or the like will install the units on the target person. Then, the control unit 1100 confirms that the unit is mounted (step S105). Here, the unit to be mounted first may be referred to as a basic unit (basic unit) or a first unit.

The first unit may be a unit predetermined by the staff or the like. Further, the first unit may be a unit for acquiring the minimum necessary biometric information. Further, the control unit 1100 may determine whether or not a basic unit is present (mounted) based on an operation performed by a staff member or the like. Further, the control unit 1100 may be determined to be mounted when it is in a state where it can communicate with the first unit or when a signal can be received from the first unit.

Here, the first unit mounted on the subject operates as the sensor device 2000. The control unit 1100 executes the first information acquisition process for acquiring the information of the target person from the sensor device 2000 (step S110). When the control unit 1100 executes the first information acquisition process, the control unit 1100 stores the target person's information (first information) acquired from the sensor device 2000 in the storage unit 1200.

Subsequently, the determination unit 1102 of the control unit 1100 determines the state of the target person from the acquired first information (S120). An example of the subject's condition is as follows.

(1) The control unit 1100 acquires the sleep time of the subject by the acceleration sensor. Then, the determination unit 1102 determines that the subject is sleeping when the fluctuation of the body movement does not continue for a certain period of time or more, and when the average sleep time of the subject is 6 hours or less, the determination unit 1102 determines that the subject is sleeping. Is determined to be a state of lack of sleep.

(2) When the control unit 1100 measures an odor (middle fat odor, aging odor) equal to or higher than a reference value by an odor test for, for example, one hour or more, the control unit 1100 determines that the subject's condition is odor.

(3) When the pH of the skin of the control unit 1100 is 4.5 or less or 6 or more by the pH sensor and UV-A is 800 kJ / m ² or UV-B is 20 kJ / m ² or more by the ultraviolet sensor. , The condition of the subject is judged to be a condition with a high risk of stains.

The state of the target person to be determined by the determination unit 1102 is an example, and it is determined whether the target person is in a predetermined state as necessary. The determination unit 1102 may determine the state of the target person based on whether it matches a predetermined condition, or may use machine learning to determine the state of the target person. The determination unit 1102 may output the determined state of the target person to the unit determination unit 1104, or may store it once in the storage unit 110.

Subsequently, the control unit 1100 (unit determination unit 1104) executes a process (recommended process) for recommending an additional unit (step S130). The unit determination unit 1104 determines the unit to be added according to the state of the target person determined by the determination unit 1102.

Here, the unit determination unit 1104 may present a plurality of recommended patterns before determining an additional unit. For example, when the determination unit 1102 determines that the subject's condition is "lifestyle-related disease", countermeasures are recommended as a detailed check. For example, the unit determination unit 1104 presents a detailed check by "hypertension", "hyperglycemia", and "periodontal disease" as a countermeasure item. The control unit 1100 may display countermeasure items on the display unit 1400. Further, the control unit 1100 may display one or a plurality of countermeasure items on the display unit 1400 and have the staff or the like select the countermeasure items.

When a countermeasure item is selected by a user such as a staff member, the unit determination unit 1104 may determine a unit corresponding to the selected countermeasure item.

Then, the unit determination unit 1104 recommends the determined unit (second unit) to the user such as the staff. For example, the control unit 1100 displays the type of unit to be added to the display unit 1400 (that is, the type of unit in which the detection unit (sensor) for acquiring necessary information in the sensor device 2000 is mounted). ..

The control device 1000 may not only display the type of the unit to be added on the display unit 1400, but also notify the unit via the notification unit 1450 or send an e-mail via the communication unit 1500. When the subject accesses a predetermined website, the control device 1000 may display a recommendation of the type of unit to be added. Further, the control device 1000 may make a report according to the type, importance, and urgency of the unit to be added.

[4.2 Other processing]
The control unit 1100 only determined and recommended the additional units required in the process of FIG. In the process of FIG. 11, the control unit 1100 executes the evaluation process based on the information (second information) acquired from the additional unit. Here, steps S100 to S130 are the same processes as those in FIG.

When the second unit, which is the unit recommended in step S130, is attached (step S210; Yes), the information acquisition unit 1106 of the control unit 1100 executes an information acquisition process for acquiring information of the target person (step S220). ..

In the information acquisition process of step S220, the information acquisition unit 1106 acquires the information of the target person as in the information acquisition process of step S110. Here, the information acquisition process in step S220 acquires the first information from the first unit and the second information from the second unit. The information acquisition unit 1106 may acquire the first information and / or the second information (parameter) used in the evaluation process (step S230) in the information acquisition process.

Then, the control unit 1100 executes the evaluation process based on the acquired information (first information and / or second information). For example, the control unit 1100 can evaluate from the acquired information whether or not the subject has more sleep, has a problem with body odor, and has not deteriorated cardiopulmonary function. Then, the control unit 1100 may display the evaluated content on the display unit 1400.

That is, according to the process of FIG. 11, the control unit 1100 recommends the second unit to be added based on the first information output by the first unit. Further, when the subject wears the second unit, the control unit 1100 acquires, in addition to the first information, the second information output by the second unit added by recommendation.

As a result, the control unit 1100 determines the state of the target person, etc., which has been determined only by the first information, based on the content of the first information and the content of the second information recommended by referring to the first information. It becomes possible to evaluate. In the system of the present embodiment, the staff can freely customize the combination of the first information and the second information for each target person, and can acquire the first information and the second information according to each target person. As a result, the state of each subject can be accurately grasped as compared with the preceding sensor device.

[4.3 System processing]
In FIGS. 10 and 11, the overall outline of the system 1 as the operation of the control device 1000 has been described. FIG. 12 specifically describes the flow of processing between the sensor device 20, the terminal device 10, and the server device 30.
In FIG. 12, the terminal device 10 acquires the information of the target person. Then, the terminal device 10 transmits the information of the target person to the server device 30. As a result, the server device 30 is an example of executing a process for determining an additional unit and evaluating a target person.

As shown by the broken line, the process of the system 1 in FIG. 12 executes the process of determining the first unit. When the user selects the content to be determined as the state of the target person (S1002), the terminal device 10 transmits a unit request including information indicating the selection to the server device 30 (S1004). The unit request includes, for example, information indicating that the subject wants to determine the sleep state and information indicating that the subject wants to determine a lifestyle-related disease. For example, the content to be determined as the state of the target person is the content of the "determination" in FIG.

The unit determination unit 304 of the server device 30 determines the first unit based on the received unit request (S1006). For example, when the user selects that he / she wants to determine the state of “sleep”, the unit determination unit 304 determines that the first unit of the sensor device 20 requires an acceleration sensor device. Further, when the user selects that he / she wants to determine the state of “body odor”, the unit determination unit 304 determines that two devices, a diacetyl sensor and a 2-nonenal sensor, are required as the first unit of the sensor device 20. do.

The server device 30 notifies the staff and the like of the determined first unit. For example, the server device 30 may display the devices required for the first unit. Further, the server device 30 may transmit information about the first unit determined to the terminal device 10, and the terminal device 10 may display a device required for the first unit.

Further, the first unit may be determined in advance, or may be determined by a staff member or the like according to the condition of the target person. In this case, it is not necessary to execute the broken line portion (step S1002 to step S1006) in FIG.

The first unit composed of the necessary devices is attached to the subject (S1010). That is, the mounted first unit is the sensor device 20 that acquires the information of the target person.

The information acquisition unit 102 of the terminal device 10 acquires the information of the target person from the first unit (S1012, S1014). Here, the information acquired by the information acquisition unit 102 from the first unit is referred to as the first information. In addition to the information of the target person, the first information may include environmental information and attribute information of the target person.

Further, the information acquisition unit 102 may acquire the first information transmitted by the sensor device 20 to the terminal device 10. Further, the information acquisition unit 102 may acquire the first information by reading the first information from the sensor device 20 by the terminal device 10. Further, the information acquisition unit 102 may always acquire the first information, or may acquire the first information at a predetermined timing (for example, every 1 minute, every 5 minutes later, or every day at 9:00, 12:00, 15:00, etc.). It may be acquired at a fixed time).

The control unit 100 of the terminal device 10 transmits the first information to the server device 30, and the control unit 300 of the server device 30 receives the first information (S1016). The control unit 300 stores the received first information in the target person information storage area 312.

When the control unit 300 receives information about the environment (environmental information) from the terminal device 10, it stores it in the environmental information storage area 314. Further, when the information (attribute information) regarding the attribute of the target person is received from the terminal device 10, it is stored in the attribute information storage area 316.

The determination unit 302 of the server device 30 determines the state of the target person from the first information (for example, the information of the target person) (S1020). Note that S1020 corresponds to the determination process (step S120) of FIG. Then, based on the state of the target person determined by the determination unit 302, the unit determination unit 304 determines the second unit as the unit to be added (S1022). Then, the server device 30 transmits the information of the second unit to the terminal device 10 (S1024).

The terminal device 10 displays information (for example, necessary devices and units) about the second unit to be worn by the target person based on the received information of the second unit (S1026). The processing of S1022 to S1026 corresponds to the recommended processing (step S130) of FIG.

By displaying the information about the second unit on the terminal device 10, the staff or the like recognizes the unit or device to be added to the sensor device 20 of the target person. Then, when the second unit is attached to the sensor device of the target person (S1028), the second information is also transmitted from the sensor device 20 to the terminal device 10 (S1030).

That is, the terminal device 10 acquires the first information and / or the second information from the sensor device 20 (S1032). Then, the terminal device 10 transmits the acquired first information and / or the second information to the server device 30 (S1034).

Then, the server device 30 executes the evaluation process based on the first information and / or the second information received from the terminal device 10 (S1036). The evaluation process is a process corresponding to the evaluation process (step S230) of FIG.

The control unit 300 of the server device 30 may transmit the evaluation result output by executing the evaluation process to the terminal device 10 (S1038). Further, the control unit 300 of the server device 30 may send an alert based on the evaluation result.

Further, the server device 30 may transmit, for example, information on an exercise program to the terminal device 10 as an evaluation result. Further, the server device 30 may transmit to the terminal device 10 that the current correspondence is to be continued as an evaluation result.

Further, the terminal device 10 may display the advice based on the evaluation result received from the server device 30 on the display unit 140. Further, the terminal device 10 may output an alert based on the evaluation result received from the server device 30 from the notification unit 150. Further, when the terminal device 10 presents the exercise program to the target person, the terminal device 10 may update the exercise program with the exercise program received from the server device 30.

Further, the terminal device 10 may print a report including the advice received from the server device 30 as an evaluation result, or may send it by e-mail.

In the processing flow of FIG. 12, the information of the target person is described as an example as the type of information, but the processing can be similarly realized even with the environmental information and the attribute information of the target person. Further, the target person's information, environment information, and attribute information may be one or a plurality of combinations.

(Concrete example)
For example, a case where an acceleration sensor is attached to a target person as a basic unit of the sensor device 20 will be described.

Here, a user such as a staff member selects in S1002 of FIG. 12 as the content to determine the "sleep" of the target person. Therefore, the server device 30 determines that the basic unit is an "accelerometer" (S1006).

Further, the information acquisition unit 102 of the terminal device 10 acquires from the first unit of the sensor device 20 whether or not the fluctuation of the body movement exceeding a certain threshold value continues for a certain period of time or more from the device including the acceleration sensor. However, the subject's awakening / sleeping state has been acquired. At the same time, the terminal device 10 has, as the information of the subject, the amount of activity based on the fluctuation of the body movement, and the large body movement (body movement exceeding a certain threshold value) that can be presumed to be walking out of bed. It is also possible to obtain the toilet frequency, sleep time, etc. calculated based on the fluctuation. The information acquisition unit 102 stores the information of the target person in the target person information storage area 112. Further, the control unit 100 transmits the acquired information of the target person to the server device 30 as the first information.

The terminal device 10 may transmit the first information to the server device 30 at predetermined time intervals (for example, every 1 minute, every 5 minutes, every 10 minutes, etc.), or at a predetermined time of the day (for example, every 10 minutes). It may be transmitted at 6:00 am and 23:00 pm), or may be transmitted when there is an operation from the user.

The determination unit 302 of the server device 30 determines the state of the target person from the information of the target person included in the first information (S1014). Here, the server device 30 has a low activity amount of the subject based on the information of the subject and a low frequency of toileting (for example, the activity amount during the day based on the fluctuation of body movement is low, and the server device 30 walks out of bed. If the number of changes in body movements that are large enough to be inferred (body movements that exceed a certain threshold) is smaller than the normal number of times for a person who has the same attributes as the subject), the subject's condition is Determined to be in a "dehydrated state". Further, when the subject's activity amount is low and the sleep time is short based on the subject's information (for example, the daytime activity amount based on the fluctuation of body movement is low, the determination unit 302 exceeds a certain threshold value). If the total amount of time that the body movement changes for a certain period of time or more is less than 6 hours), the subject's condition is determined to be "a condition with a high risk of adult disease".

Then, the unit determination unit 304 presents a countermeasure to the terminal device 10 according to the state of the target person. For example, the unit determination unit 304 presents a countermeasure for performing "hydration" or "moderate exercise" when the subject's state is "dehydrated".

Then, when "hydration" is selected as a countermeasure by the staff or the like, the unit determination unit 304 determines the external device 40 (intake sensor) as an additional device. When "moderate exercise" is selected as a countermeasure, the unit determination unit 304 determines the electrocardiographic sensor as the second unit to be added.

The terminal device 10 transmits the information (second information) acquired by the added second unit to the server device 30. For example, when "hydration" is selected as a countermeasure by the staff or the like, the determination unit 302 of the server device 30 determines whether or not the timing at which the subject ingests water is appropriate from the intake sensor (for example). When the time interval for the subject to drink water is larger than a certain threshold, it is judged that the timing for the subject to drink water is not appropriate, and when the time interval for the subject to drink water is less than or equal to the certain threshold. Is judged to be appropriate when the subject ingests water). Then, when the timing of hydration is inappropriate, the server device 30 transmits to the terminal device 10 that the timing is inappropriate.

Further, when "moderate exercise" is selected as a countermeasure by the staff or the like, the determination unit 302 of the server device 30 acquires the amount of exercise from the electrocardiographic sensor and determines whether the amount of exercise is sufficient (acquired). Whether or not the amount of exercise is sufficient is determined by whether or not the amount of exercise exceeds the threshold value (the normal amount of exercise of a person who has the same attributes as the subject). Then, when the amount of exercise of the subject is insufficient, the determination unit 302 transmits to that effect to the terminal device 10. As a result, the terminal device 10 can notify the target person and the staff that the amount of exercise is insufficient.

In addition, if the subject's condition is "high risk of adult disease", the countermeasures are to take "supplementary foods" appropriately, perform "moderate exercise", and "improve the sleeping environment". Present.

Then, when "supplementary food" is selected as a countermeasure, the unit determination unit 304 determines the external device 40 (intake sensor) as an additional device. At this time, the control unit 300 may also determine an appropriate type of supplement.

Further, when "moderate exercise" is selected by the staff or the like as a countermeasure, the unit determination unit 304 determines the device of the optical sensor as the second unit to be added. At this time, the control unit 300 may also determine an appropriate exercise program.

Further, when "improvement of sleeping environment" is selected by the staff or the like as a countermeasure, the unit determination unit 304 determines the sweating sensor as the second unit to be added. At this time, the control unit 300 may also determine an appropriate mattress or pillow.
The terminal device 10 acquires the information (second information) acquired by the added second unit together with the first information (S1032), and transmits the acquired first information and / or the second information to the server device 30. (S1034). The server device 30 executes an evaluation process from the received first information and / or second information (S1036).

For example, when "supplementary food" is selected as a countermeasure, the control unit 300 evaluates whether or not the supplementary food is properly ingested (whether or not a desired amount of the supplementary food is ingested). In addition, the control unit 300 evaluates whether or not the effect is exhibited when the subject can appropriately acquire the supplement.

If the control unit 300 determines that the supplementary food is not effective even though the subject can properly obtain the supplementary food, the control unit 300 decides to change the supplementary food and outputs the information of the changed supplementary food to the terminal device. It may be transmitted to 10.

Further, when "appropriate exercise" is selected as a countermeasure, the control unit 300 determines whether the target person is able to exercise an appropriate amount of exercise (the acquired amount of exercise is a threshold value (a person having the same attributes as the target person). Whether or not it exceeds the normal amount of exercise) is evaluated. In addition, the control unit 300 determines whether or not the effect is exhibited when the subject is able to exercise an appropriate amount of exercise.

When the control unit 300 determines that the exercise program is changed and the subject evaluates that the effect is not shown or the effect is slight even though the subject is able to exercise an appropriate amount of exercise, the changed exercise program is determined. Information may be transmitted to the terminal device 10.

In addition, when "improvement of sleeping environment" is selected as a countermeasure, the control unit 300 determines whether the sleep time of the subject is appropriate (the body movement changes to exceed a certain threshold value for a certain period of time or longer). Whether or not the total amount of time spent is 6 hours or more) is determined.

When the control unit 300 evaluates that the sleep time of the subject is appropriate, the control unit 300 may transmit to the terminal device 10 to continue as it is. Further, the control unit 300 may send a message prompting the change of the mattress or the pillow to the terminal device 10 when the improvement of the sleeping time is not seen.

In the above-mentioned specific example, the device to be selected first has been described by taking a sensor device 20 equipped with an acceleration sensor as an example, but for example, a sensor (temperature / humidity sensor) for measuring the environment may be used.

In this case, the external device 40 that acquires the environmental information becomes the first device (basic unit). Then, the device added to it becomes an additional unit. Therefore, when the basic unit is the external device 40, the additional unit is the sensor device 20 that is first attached to the subject.

[4.4 screen example]
The processing of FIG. 12 will be described with reference to the screen example.

For example, FIG. 13A is an example of a display screen W100 for inputting information of a target person in the terminal device 10. First, the user inputs information such as a name, age, height, weight, symptom, and posture as information of the target person by the terminal device 10. When the server device 30 has acquired the target person's information (for example, the target person's attribute information, disease information, living information) in advance, the terminal device 10 does not need to input the target person's information.

FIG. 13B is an example of the display screen W110 that outputs information about the basic unit in the terminal device 10. The control unit 100 displays information that identifies the target person (for example, the name of the target person) on the display screen W110.

Here, a user such as a staff member selects the content to be determined in the area R110. The terminal device 10 transmits the content desired by the user to be determined to the server device 30. The server device 30 determines a basic first unit based on the content desired by the user to be determined, and transmits the first unit to the terminal device 10.

The area R120 of the display screen W110 displays information on the required unit (device). Here, after displaying the sensor device including the unit required for the subject in the area R130, it is confirmed whether or not the sensor device including the unit is attached (R130).

The control unit 100 may be confirmed by the user by a check operation whether or not the sensor device including the unit is attached. Further, the control unit 100 may determine that the sensor device 100 has been installed when the desired information can be acquired from the sensor device 20, that is, when the signal to be output from the unit can be acquired.

FIG. 14A is an example of the display screen W120 in which the second unit to be added is recommended in the terminal device 10. The display screen W120 displays in the area R120 that the subject "has a risk of lifestyle-related disease" from the awakening / sleeping state of the subject and other acquired information of the subject. Further, the display screen W120 displays the countermeasures in this case in the area R122. That is, as a lifestyle-related disease, the display screen W120 displays three of "hypertension", "hyperglycemia", and "periodontal disease".

Among them, FIG. 14 (b) shows a screen that transitions when "hypertension" is selected and determined by the user of the terminal device 10. The display screen of FIG. 14B displays a second unit "sphygmomanometer" to be added as a device to be added to the area R130.

As a result, the user, the staff, and the like can know the necessary sensor device 20 and the external device 40 to the target person (A in this case).

Further, even if the sphygmomanometer is attached to the subject, when an abnormal value or the like is detected, the terminal device 10 notifies the subject.

For example, the display screen W140 of FIG. 15 displays the most recently measured blood pressure value in the region R140 together with the warning message “Current blood pressure is high !!!”. In this way, the user can wear an appropriate sensor device. Further, in the case of a highly urgent message, it is possible to notify the terminal device 10 used by the staff or the like.

Further, the display screen W140 is provided with a history display button B140. The history display button B140 can display past target person information (for example, biometric information value) and environment information. In addition, the past target person information may include advice from the user and the like.

For example, the terminal device 10 may be able to output a report. For example, FIG. 16A is a display screen W150 showing an example of a report. On the display screen W150, for example, the evaluation values from the measured values are displayed in a list. Further, FIG. 16B is a display screen W160 in which the evaluation value of the display screen W150 is displayed in a graph.

[5. Processing example]
Hereinafter, an example of the processing in the present embodiment will be described. FIG. 17 is a table for explaining an example of processing in this embodiment. FIG. 17 shows a basic first unit, contents determined from the first unit, and a second unit recommended as an additional unit. In addition, each unit indicates the type of device included in the unit and the information output from each device.

[5.1 First Treatment Example (Sleep Deprivation)]
The first processing example is a processing example when the control device 1000 determines sleep deprivation. The control unit 1100 of the control device 1000 uses an acceleration sensor as a basic first unit, and acquires the awakening / sleeping state of the subject. Specifically, it measures whether or not it is sleeping from the detected acceleration (for example, if the fluctuation of body movement such as turning over does not continue for a certain period of time or more, it is determined to be sleep), and the sleep time is acquired.

For example, when the average sleep time of the subject is 6 hours or less, the control device 1000 (determination unit 1102) determines that sleep deprivation is insufficient. The unit determination unit 1104 determines "insufficient exercise" and "disordered eating habits" as countermeasure items.

Then, when "insufficient exercise" is selected as a countermeasure item, the unit determination unit 1104 determines the unit equipped with the device of the acceleration sensor as the second unit and displays it on the display unit 1400. Since one acceleration sensor is added to the sensor device 2000, the determination unit 1102 determines the posture and movement from the information acquired by the information acquisition unit 1106, and determines whether or not it is appropriate (the added acceleration sensor determines. When attached to the specified thigh, for example, when the acceleration that can be acquired by the added accelerometer exceeds the threshold value (acceleration enough for the subject to walk or run) for a certain period of time or longer, the determination unit 1102 determines that the subject is exercising).

Further, when "disordered eating habits" is selected as a countermeasure item, the unit determination unit 1104 determines the unit equipped with the device equipped with the acetone sensor as the second unit and displays it on the display unit 1400. The determination unit 1102 determines from the nutritional state based on the acetone sensor acquired by the information acquisition unit 1106 whether or not the diet is properly performed (whether or not the nutritional state based on the acetone sensor is ingested above the threshold value).

[5.2 Second Treatment Example (Lifestyle-related Disease)]
The second processing example is a processing example when the control device 1000 determines the lifestyle-related disease of the subject. The control unit 1100 detects acceleration from the first unit including the device of the acceleration sensor, and acquires the awakening / sleeping state of the subject and the movement of the subject.

Then, when the standard deviation of any of the sleep time, the sleep onset time, and the wake-up time of the subject is 3 hours or less, the determination unit 1102 determines that the subject's condition is a lifestyle-related disease based on an irregular life. In that case, the unit determination unit 1104 lists detailed checks due to "hypertension", "hyperglycemia", and "periodontal disease" as countermeasure items, and additionally provides a second unit according to the selected countermeasure.

When "hypertension" is selected as a countermeasure, the unit determination unit 1104 determines the second unit including the device of the sphygmomanometer. Further, when "hyperglycemia" is selected as a countermeasure, the unit determination unit 1104 determines the second unit including the device of the acetone sensor. The control unit 1100 acquires the blood glucose level based on the information from the acetone sensor acquired by the information acquisition unit 1106.

When "periodontal disease" is selected as a countermeasure, the unit determination unit 1104 determines the second unit including the device of the germ amount sensor. As a result, the control unit 1100 acquires the amount of bacteria from the bacteria amount sensor acquired by the information acquisition unit 1106, and acquires the amount of bacteria that cause periodontal disease, thereby causing periodontal disease. Determine the risk (determine the risk of periodontal disease based on whether the amount of germs exceeds the threshold).

As described above, in the control device 1000, the content to be determined and the second unit to be added are determined from the first unit according to the processing table shown in FIG. Further, the control device 1000 can evaluate the state of the subject from the combination of the first unit and the second unit. Further, the control device 1000 outputs an alert, outputs an advice, and creates an evaluation report according to the evaluation result.
