Description

Technical Field

[0011]

[0001] The present invention relates to a monitoring system, a monitoring program, and a monitoring method for the elderly, care recipients, patients, etc.

Background Art

[0002] In recent years, the proportion of children living apart from their elderly parents has been increasing. Also, many elderly people have concerns about their own and their family members' health.

[0003] Many elderly people have concerns about their own health and sudden deterioration of their physical condition.

[0004] Many family members of the elderly are worried about detecting changes in their family members living apart and delays in response.

[0005] Local governments, the government, etc. are concerned about problems such as lonely deaths and disappearances of wanderers.

[0006] Nursing facilities, etc. have problems such as detecting changes in care recipients and delays in response, health management of care recipients, disappearances of wanderers, and shortages of nursing staff, etc.

[0007] Similarly, hospitals have problems such as detecting changes in patients and delays in response, health management of patients, disappearances of wanderers, and shortages of nurses, etc.

[0008] Also, many patients and elderly people prefer to receive treatment or care at home rather than being hospitalized or living in a nursing facility.

[0009] On the other hand, when nurses, caregivers, etc. visit to monitor patients, elderly people, etc., there is a problem that it takes a very long time to visit each house. Especially in rural areas, such problems are serious.

[0010] In Patent Document 1, a wearable sensor system for detecting changes in a user's physical condition is disclosed.

[0011] Specifically, the wearable sensor system described in Patent Document 1 includes a first wearable sensor terminal that acquires information on cardiac function from a living organism, A second wearable sensor terminal that acquires information about blood flow from the living body, The device includes a determination device that determines the state of a living organism in relation to thermal damage based on information about cardiac function acquired by a first wearable sensor terminal, information about blood flow acquired by a second wearable sensor terminal, and information about the temperature of the living organism's geographical location.

[0012] Patent Document 2 discloses a device that allows the location and physical condition of a person possessing a mobile terminal registered with the safety confirmation device to be confirmed without the person having to dial a number, and furthermore, even if the mobile terminal malfunctions, it is possible to quickly estimate the person's location with high accuracy, with the aim of helping to promptly contact relevant parties and to quickly rescue and treat victims.

[0013] Specifically, the invention described in Patent Document 2 involves monitoring the distance traveled, body temperature, and heart rate changes of a person carrying a mobile terminal registered with the safety confirmation device at desired intervals. If an abnormality is detected, the device refers to the log data to detect or estimate the person's location and contacts the relevant parties. [Prior art documents] [Patent Documents]

[0014] [Patent Document 1] Japanese Patent Publication No. 2017-38839 [Patent Document 2] Japanese Patent Publication No. 2006-120060 [Overview of the Initiative] [Problems that the invention aims to solve]

[0015] However, the invention described in Patent Document 1 relates to a wearable sensor system for detecting changes in a person's condition in a hot environment, such as in order to prevent heatstroke.

[0016] Therefore, it is insufficient for quickly detecting sudden illnesses or injuries in the elderly other than heatstroke. Furthermore, it does not describe what happens after detection.

[0017] The invention described in Patent Document 2 monitors the changes in travel distance, body temperature, and heart rate at desired intervals for a person carrying a mobile terminal registered with a safety confirmation device.

[0018] However, it is insufficient for quickly detecting sudden illnesses or injuries among the elderly. Furthermore, it only states that relevant parties will be contacted, without specifying the details of what to do.

[0019] The main objective of this invention is to provide a system that can quickly detect and respond to sudden illnesses or injuries in elderly individuals or patients.

[0020] Another object of the present invention is to provide a program that can quickly detect and respond to sudden illnesses or injuries in elderly people or patients.

[0021] Another object of the present invention is to provide a method that can quickly detect and respond to sudden illnesses or injuries in elderly people or patients. [Means for solving the problem]

[0022] A monitoring system for the elderly and others according to the first aspect of the present invention is a monitoring system for the elderly and others comprising a server that can communicate with a first terminal held by the target person, including the elderly, a second terminal held by the target person's caregiver, and a third terminal used by a doctor or nurse, The aforementioned server, A body temperature determination unit that determines the body temperature of the subject based on the body temperature information transmitted from the first terminal. A heart rate determination unit that determines the heart rate of the subject based on the heart rate information transmitted from the first terminal. A heat stroke determination unit that determines whether there is a risk of heat stroke for the subject based on the air temperature information, humidity information, and radiant heat information transmitted from the first terminal, the body temperature of the subject determined by the body temperature determination unit, and the heart rate of the subject determined by the heart rate determination unit. An abnormality determination unit that determines whether the body temperature determination unit, the heart rate determination unit, the body temperature and heart rate of the subject are normal or abnormal, and determines that it is abnormal when it is determined in the heat stroke determination unit that there is a risk of heat stroke. A WBGT determination unit that notifies the first terminal and the third terminal when it is determined that the WBGT value is high. A position signal determination unit that determines the position of the subject based on the position signal transmitted from the first terminal, and includes: When the abnormality determination unit determines that it is abnormal, information on the body temperature, heart rate, or risk of heat stroke determined to be abnormal, and the content of the abnormality are transmitted to the third terminal. The third terminal includes a diagnosis unit that communicates with the first terminal in a communicable manner for diagnosing the subject. Based on the determination of the position signal determination unit, a vehicle dispatch unit that dispatches a vehicle including an ambulance to the subject. A monitoring system for a subject including an elderly person in which a doctor who is a user of the third terminal diagnoses the subject through the diagnosis unit, and based on the doctor's judgment, the vehicle dispatch unit dispatches a vehicle to the position specified by the position signal determination unit.

[0023] Whether there is an abnormality in the body temperature and heart rate of the monitored subject such as an elderly person who is the owner of the first terminal, and whether there is a risk of heat stroke can also be known to the owners of the second terminal and the third terminal at a distant location, so that if there is an abnormality, it can be responded to immediately.

[0024] Furthermore, if the third terminal receives an abnormality notification, a doctor will diagnose the person through the diagnostic unit of the third terminal, providing reassurance to the elderly person and their family members who use the second terminal.

[0025] Furthermore, the diagnostic unit can forcibly enable communication between the first and third terminals. Whether or not to forcibly enable communication can be set in advance.

[0026] Furthermore, the third terminal's location signal determination unit allows it to determine the location of the first terminal. Therefore, if something happens to the person being monitored, such as an elderly person, the dispatch unit of the third terminal can immediately dispatch an ambulance to that location.

[0027] In other words, it allows for the immediate detection of sudden illnesses or other emergencies in elderly or other individuals being monitored, enabling a swift response.

[0028] The monitoring system for the elderly and others according to the second aspect of the present invention is the monitoring system for the elderly and others according to the first aspect, The server includes a blood pressure determination unit that determines the blood pressure of the subject based on the heart rate information and the blood flow information transmitted from the first terminal, A blood glucose level determination unit that determines the blood glucose level of the subject based on the blood glucose level information transmitted from the first terminal, A step count determination unit that determines the number of steps taken by the subject based on information transmitted from the acceleration sensor and geomagnetic sensor of the first terminal, A sleep determination unit that determines the sleep state of the subject based on heart rate information transmitted from the first terminal, The system includes a sweat determination unit that determines the sweating state of the subject based on sweat information transmitted from the first terminal, The abnormality detection unit determines whether the blood pressure, blood glucose level, sleep state, and sweating state determined by the blood pressure detection unit and the blood glucose level detection unit are abnormal, and this is a monitoring system for subjects including the elderly.

[0029] As we age, insulin secretion decreases, and even when insulin is secreted, its effectiveness diminishes, which is why the frequency of developing diabetes increases with age.

[0030] Furthermore, as people age, the progression of arteriosclerosis throughout the body accelerates, and some individuals suffer from multiple related conditions such as hypertension and dyslipidemia (hyperlipidemia). Diabetic complications such as retinopathy and neuropathy are also frequently observed.

[0031] Diabetes is a disease that is inherently difficult to detect, but in the elderly, the decline in physical function makes it even harder to notice symptoms. Also, even if there are abnormalities, they may be overlooked by attributing them to age, so the progression of arteriosclerosis may lead to quite advanced diabetic complications.

[0032] Therefore, it is important to regularly measure the blood glucose levels of elderly individuals and other target groups.

[0033] By knowing the subject's step count, sleep patterns, and sweating patterns, it becomes possible to better understand the subject's condition.

[0034] The monitoring system for the elderly and others according to the third aspect of the present invention is the monitoring system for the elderly and others according to the first aspect, The server includes a fall determination unit that determines whether or not the subject has fallen based on information transmitted from the acceleration sensor and geomagnetic sensor of the first terminal. The abnormality detection unit determines that an abnormality has occurred when the fall detection unit determines that the subject has fallen, and transmits that information to the third terminal, in the subject monitoring system for elderly persons and other persons according to claim 1.

[0035] If the subject falls, the doctor or nurse using the third terminal can check the subject's condition using the diagnostic unit and respond quickly.

[0036] The fourth aspect of the present invention is a monitoring system for the elderly and others, which is a monitoring system for the elderly and others, which is a third aspect of the present invention.

The abnormality detection unit determines that an abnormality exists when the fall detection unit determines that the subject has fallen and the stagnation detection unit determines that the subject is stagnant, and transmits this information to the third terminal, in the subject monitoring system for elderly persons as described in claim 3.

[0037] If a person falls and remains motionless for a period of time, it can be determined that they are in a dangerous condition. The doctor or nurse using the third terminal will then check on the person through the diagnostic department, and if necessary, the dispatch department will arrange for an ambulance to be dispatched.

[0038] The monitoring system for the elderly and others according to the fifth aspect of the present invention is the monitoring system for the elderly and others according to the first aspect, The server includes an SpO2 determination unit that determines the oxygen concentration in the subject's blood based on information transmitted from the SpO2 sensor of the first terminal, The abnormality determination unit determines, based on the oxygen concentration information determined by the SpO2 determination unit, whether or not the subject may have sleep apnea syndrome, in the subject monitoring system for elderly persons, as described in claim 1.

[0039] By measuring the oxygen concentration in the blood, it is possible to determine whether or not a subject has sleep apnea syndrome.

[0040] In cases of sleep apnea, the inability to get deep sleep leads to excessive daytime sleepiness, decreased concentration, and an increased risk of traffic accidents and work-related accidents due to drowsiness.

[0041] Furthermore, repeated episodes of apnea and hypopnea can lead to hypoxia, putting a strain on the heart. This increases the risk of complications such as hypertension, diabetes, myocardial infarction, and stroke. In the worst cases, it can even lead to sudden death.

[0042] Therefore, it is important to measure the oxygen concentration in the subject's blood.

[0063] [Figure 1] A conceptual diagram of a monitoring system for elderly individuals and other subjects according to one embodiment of the present invention. [Figure 2] A conceptual diagram of a monitoring system for target individuals, including the elderly, in the same embodiment. [Figure 3] A conceptual diagram of a monitoring system for target individuals, including the elderly, in the same embodiment. [Modes for carrying out the invention]

[0064] Hereinafter, embodiments of the monitoring system 100 according to the present invention will be described with reference to the drawings.

[0065] As shown in Figures 1 and 2, the monitoring system 100 of this embodiment includes a first terminal 200 held by the person to be monitored, such as an elderly person A, A server 300 that can communicate with the first terminal 200, The second terminal 600 is notified when it is determined that there is an abnormality in person A, The system includes a third terminal 700 that can communicate with server 300 and receive notifications of information about subject A from server 300.

[0066] The first terminal 200 measures the subject A's vital signs (vital information, etc.) such as heart rate, brain waves, respiration, body temperature, sweating, blood pressure, and exercise status, and transmits this vital information to the server 300.

[0067] As shown in Figure 2, in this embodiment, the first terminal 200 includes various sensors, including a body temperature sensor S1, an optical heart rate sensor S2, an acceleration sensor S3, a geomagnetic sensor S4, a blood glucose sensor S5, an SpO2 sensor S6, a sweat sensor S7, an air temperature sensor S8, a humidity sensor S9, and a black globe temperature sensor S10. A first storage unit 210 that stores the sensed information, A first communication unit 220 transmits the sensed information to the server 300, It includes a first position signal unit 230 that indicates the location information of subject A.

[0068] Furthermore, the server 300 in this embodiment includes a body temperature determination unit 310, a heart rate determination unit 320, a step count determination unit 330, a blood pressure determination unit 340, a blood glucose level determination unit 350, an SpO2 determination unit 360, a sleep determination unit 370, a sweating determination unit 380, a fall determination unit 390, a stagnation determination unit 400, a heatstroke determination unit 410, an abnormality determination unit 420, a communication unit 430, a storage unit 440, a position signal determination unit 450, and a WBGT determination unit 460. Specific details will be described later. Note that the server 300 may be a cloud server.

[0069] (Terminal 1, 200) The first terminal 200 is preferably waterproof. The first terminal 200 is preferably a wearable device, and in this embodiment, a watch is used. The first terminal 200 may also be applied to the skin of subject A. Subject A is, for example, an elderly person, a caregiver for dementia, or a home-care patient.

[0070] The body temperature sensor S1 measures the body temperature of subject A. In this embodiment, the body temperature of subject A is measured for 24 hours. The body temperature sensor S1 in this embodiment is an infrared sensor.

[0071] The body temperature sensor S1 is preferably designed to continuously measure the body temperature of subject A over 24 hours, but it may also measure at predetermined intervals, such as every minute or every hour.

[0072] The body temperature information of subject A, which has been measured, is transmitted to the server 300 via the first communication unit 220.

[0073] The body temperature sensor S1 may, for example, measure body temperature by placing thermistors at two locations and measuring the heat flux between the two points.

[0074] The body temperature sensor S1 may be applied to a central area such as the chest of subject A for measurement.

[0075] The body temperature information measured by the body temperature sensor S1 is transmitted to the server 300, and the body temperature determination unit 310 of the server 300 determines the body temperature of subject A. The body temperature determination unit 310 may also take into account the movement of subject A measured by the acceleration sensor S3 and the heart rate sensor S2 when making its determination.

[0076] In this embodiment, for example, if the body temperature sensor S1 detects a temperature of 37.5 degrees or higher three times in a row, the body temperature determination unit 310 determines that the body temperature of subject A is 37.5 degrees or higher, and based on this, the abnormality determination unit 420 determines that there is an abnormality.

[0077] Furthermore, in this embodiment, if the ambient temperature sensor S8 detects a temperature of 32 degrees or higher, and the body temperature sensor S1 detects a temperature of 38 degrees or higher three times in a row, the heatstroke determination unit 410 determines that subject A may be suffering from heatstroke, and the abnormality determination unit 420 determines that there is an abnormality.

[0078] The heart rate sensor S2 measures the heart rate of subject A.

[0079] In this embodiment, the heart rate sensor S2 irradiates light from an LED and measures the amount of scattered light reflected by blood flow.

[0080] Furthermore, the heart rate information measured by the heart rate sensor S2 may be used for body temperature measurement by the body temperature determination unit 310.

[0081] When blood flow dynamics change due to fluctuations in pulse rate or blood volume (cardiac output), the light penetrating the body is reflected (scattered) in a predictable manner in response to these changes, allowing the heart rate sensor S2 to measure the heart rate.

[0082] In other words, the heart rate sensor S2 measures heart rate by analyzing the reflected light from an LED that shines several hundred times per second.

[0083] This allows the first terminal 200 to continuously measure the heart rate of subject A for 24 hours.

[0084] The heart rate information measured by the heart rate sensor S2 is transmitted to the server 300, and the heart rate determination unit 320 of the server 300 determines the heart rate of subject A.

[0085] The heart rate sensor S2 may also measure the heart rate of subject A using bioelectrical impedance analysis.

[0086] In this embodiment, if the heart rate sensor S2 detects a heart rate of 40 beats or less three times in a row, the heart rate determination unit 320 determines that the heart rate of subject A is 40 beats or less, and the abnormality determination unit 420 determines that it is abnormal.

[0087] Furthermore, in this embodiment, if the heart rate sensor S2 detects 160 beats or more 10 times in a row, the heart rate determination unit 320 determines that the heart rate of subject A is 160 beats or more, and the abnormality determination unit 420 determines that it is abnormal.

[0088] Furthermore, in this embodiment, if the heart rate sensor S2 detects a heart rate of "180 minus (age)" or higher, the abnormality detection unit 420 transmits this information to the third terminal 700. If a heart rate of "180 minus (age)" or higher is detected for a predetermined period of time or longer, a warning message such as "Heatstroke warning. Please replenish fluids." is displayed on the display screen of the first terminal 200.

[0089] The abnormality detection unit 420 then transmits this information to the third terminal 700, and an alert is sent to the third terminal 700.

[0090] Furthermore, by measuring subject A's heart rate while they are sleeping, it is possible to understand subject A's sleep state.

[0091] In other words, the sleep state of subject A is determined by the sleep determination unit 370 of the server 300, after the measured heart rate information is transmitted to the server 300.

[0092] The accelerometer S3 measures the movement and posture of subject A. Alternatively, a gyroscope or angular velocity sensor may be used to sense the movement and posture of subject A.

[0093] Information from the acceleration sensor S3 is transmitted to the server 300. The information from the acceleration sensor S3 is used by the body temperature determination unit 310, heart rate determination unit 320, step count measurement unit 330, blood pressure determination unit 340, sleep determination unit 370, fall detection unit 390, and stagnation detection unit 400.

[0094] For example, if subject A is exercising, the body temperature determination unit 310 can determine that subject A is exercising, even if the body temperature sensor S1 shows a body temperature higher than the standard, by transmitting the information sensed by the acceleration sensor S3 to the server 300.

[0095] This allows the abnormality detection unit 420 to determine whether or not the body temperature of subject A is abnormal. Alternatively, the abnormality detection unit 420 may determine that subject A is exercising based on the information sensed by the acceleration sensor S3.

[0096] Furthermore, if subject A is exercising, the acceleration sensor S3 transmits the sensed information to the server 300, allowing the heart rate determination unit 320 to determine that subject A is exercising, even if the heart rate is higher than the standard.

[0097] This allows the abnormality detection unit 420 to determine whether or not the heart rate of subject A is abnormal. The abnormality detection unit 420 may also determine that subject A is exercising based on the information sensed by the acceleration sensor S3, and the heart rate detection unit 320 may determine that subject A is exercising based on the information from the body temperature detection unit 310.

[0098] When subject A turns over in their sleep, the acceleration sensor S3 transmits the sensed information to the server 300, allowing the sleep determination unit 370 to determine subject A's sleep state.

[0099] The geomagnetic sensor S4 detects the tilt of the first terminal 200 relative to the ground. The information sensed by the geomagnetic sensor S4 is transmitted to the server 300, and the step counting unit 230 extracts the vertical acceleration value relative to the ground from the acceleration sensor S3.

[0100] This allows the step count determination unit 330 to measure the number of steps taken by subject A.

[0101] In other words, in this embodiment, the step count determination unit 330 determines the number of steps taken by subject A using the acceleration sensor S3 and the geomagnetic sensor S4.

[0102] Furthermore, the fall detection unit 390 detects whether or not subject A has fallen using the acceleration sensor S3 and the geomagnetic sensor S4.

[0103] In this embodiment, when the fall detection unit 390 detects that subject A has fallen, the display screen of the first terminal 200 displays "Fall detected. Do you want to call for help? 'Yes' / 'No'." Subject A can then select "Yes" or "No" using the touch panel.

[0104] If "yes" or "no" is not selected within 20 seconds, an alert will be sent to the third terminal 700.

[0105] Similarly, the stagnation determination unit 400 determines whether or not subject A is stagnating based on the acceleration sensor S3 and the geomagnetic sensor S4.

[0106] In this embodiment, if the fall detection unit 390 determines that subject A has fallen, and the stagnation detection unit 400 subsequently determines that "subject A has been inactive (staying idly) for 3 minutes," the abnormality detection unit 420 determines that there is an abnormality.

[0107] The S5 blood glucose sensor uses a high-power mid-infrared laser to sense even the slightest information about blood glucose levels.

[0108] Specifically, because mid-infrared light is greatly absorbed by glucose, when a high-power mid-infrared laser is shone onto the skin, some of the light particles are absorbed by glucose, and the unabsorbed light is reflected by the skin.

[0109] The first terminal 200 then detects the reflected light with a detector and transmits information about the difference between the incident light and the reflected light to the server 300. The blood glucose level determination unit 350 of the server 300 then calculates the blood glucose level from that information.

[0110] In other words, the blood glucose sensor S5 in this embodiment is a non-invasive blood glucose sensor.

[0111] This allows diabetic patients to manage their blood sugar levels daily without pain. Furthermore, it is expected to help curb the increase in the diabetic population through prevention and health management among healthy individuals.

[0112] The information sensed by the blood glucose sensor S5 is transmitted to the server 300, and the blood glucose determination unit 350 determines the blood glucose level of subject A based on that information.

[0113] The SpO2 sensor S6 senses SpO2 (Saturation Pulse O2, transcutaneous arterial blood oxygen saturation). In other words, it detects the oxygen concentration in the blood of subject A.

[0114] The information sensed by the SpO2 sensor S6 is transmitted to the server 300, and the SpO2 determination unit 360 determines the SpO2 of subject A.

[0115] The SpO2 determination unit 360 can determine the sleep apnea syndrome of subject A by determining the SpO2 level.

[0116] The sweat sensor S7 senses the sweating state of subject A. The information sensed by the sweat sensor S7 is transmitted to the server 300, and the sweat determination unit 380 determines the sweating state of subject A.

[0117] The abnormality detection unit 420 determines whether or not there is an abnormality based on information such as the subject A's body temperature, exercise status, heart rate, and sweating status.

[0118] In this embodiment, the first position signal unit 230 transmits location information of subject A.

[0119] In this embodiment, the first position signal unit 230 is capable of receiving GPS (Global Positioning System) signals. This allows the location of the subject A, who is the owner of the first terminal 200, to be determined by GPS.

[0120] To explain in more detail, satellites constantly transmit their "current location" and "current time." When the first position signal unit 230 (GPS satellite receiver) of the first terminal 200 receives a radio signal from the satellite, the first position signal unit 230 calculates the distance between the satellite and the first position signal unit 230 by multiplying the time it took for the signal to arrive by the speed of the radio waves.

[0121] This process is repeated with multiple satellites orbiting the area of ​​subject A. Then, the current location of the first terminal 200 is determined from the calculated distances to the multiple satellites.

[0122] The current location of the identified first terminal 200 is transmitted to the server 300 via the first communication unit 220.

[0123] The first position signal unit 230 may also transmit the location information of the first terminal 200 to the server 300 using a beacon or Bluetooth®.

[0124] The first storage unit 210 stores information sensed by the body temperature sensor S1, heart rate sensor S2, acceleration sensor S3, geomagnetic sensor S4, blood glucose sensor S5, SpO2 sensor S6, sweat sensor S7, and air temperature sensor S8, humidity sensor S9 or black globe temperature sensor S10.

[0125] In this embodiment, the first terminal 200 has a first storage unit 210, but the sensed information may not be stored in the first terminal 200 but may be transmitted directly to the server 300.

[0126] The first communication unit 220 can communicate with the communication unit 430 of the server 300.

[0127] The first communication unit 220 transmits the information sensed by the body temperature sensor S1, heart rate sensor S2, acceleration sensor S3, geomagnetic sensor S4, blood glucose sensor S5, SpO2 sensor S6, sweat sensor S7, air temperature sensor S8, humidity sensor S9, or black globe temperature sensor S10 to the communication unit 430 of the server 300.

[0128] (Server 300) The server 300 of this embodiment includes a body temperature determination unit 310 that determines the body temperature of subject A based on information sensed by a body temperature sensor S1, etc. A heart rate determination unit 320 determines the heart rate of subject A based on information sensed by the heart rate sensor S2, A step count determination unit 330 determines the number of steps taken by subject A based on information sensed by the acceleration sensor S3 and the geomagnetic sensor S4, A blood pressure determination unit 340 determines the blood pressure of subject A from the heart rate of subject A determined by the heart rate determination unit 320, A blood glucose level determination unit 350 determines the blood glucose level of subject A based on information from the blood glucose sensor S5, The SpO2 determination unit 360 determines the SpO2 of subject A based on information from the SpO2 sensor S6, A sleep determination unit 370 determines the sleep state of subject A based on the heart rate determined by the heart rate determination unit 320 and the information sensed by the acceleration sensor S3, A sweat determination unit 380 determines the sweating state of subject A based on information sensed by the sweat sensor S7 and the acceleration sensor S3, A fall determination unit 390 determines whether or not subject A has fallen based on information sensed by the acceleration sensor S3 and the geomagnetic sensor S4, A stagnation determination unit 400 determines whether or not subject A is stagnant based on information sensed by the acceleration sensor S3 and the geomagnetic sensor S4, A heatstroke determination unit 410 determines whether or not subject A has heatstroke based on the determinations of the body temperature determination unit 310 and the heart rate determination unit 320, Based on the results of the assessment, an abnormality determination unit 420 determines whether or not there is an abnormality in subject A, A communication unit 430 that communicates with the first terminal 200 and the second terminal 600, etc. A memory unit 440 that stores the judgment result, A location signal determination unit 450 determines the location of subject A based on location information transmitted from the first terminal 200, The system includes a WBGT determination unit 460 that calculates the WBGT (Wet Bulb Globe Temperature) value in the environment where subject A is present, based on information sensed by the temperature sensor S8, humidity sensor S9, and black globe temperature sensor S10.

[0129] The body temperature determination unit 310 determines the body temperature of subject A based on the information sensed by the body temperature sensor S1.

[0130] The body temperature determination unit 310 may determine the body temperature of subject A by considering the movement of subject A measured by the acceleration sensor S3, or by considering the heart rate of subject A measured by the heart rate sensor S2.

[0131] If the body temperature of subject A, as determined by the body temperature determination unit 310, is outside a predetermined range (for example, 36.2 degrees Celsius or lower, or 37.5 degrees Celsius or higher), the abnormality detection unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0132] The abnormality detection unit 420 determines whether the body temperature of subject A is abnormal based on the information sensed by the acceleration sensor S3.

[0133] In other words, for example, if subject A is exercising, their body temperature will be higher than normal. Therefore, if the abnormality detection unit 420 determines that subject A is exercising based on the acceleration sensor S3, it takes this into consideration when determining whether subject A's body temperature is abnormal.

[0134] The heart rate determination unit 320 determines the heart rate of subject A based on the heart rate information measured by the heart rate sensor S2.

[0135] If the heart rate of subject A, as determined by the heart rate determination unit 320, is outside a predetermined range (for example, 59 or less, or 91 or more), the abnormality detection unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0136] The abnormality detection unit 420 determines whether the heart rate of subject A is abnormal based on the information sensed by the acceleration sensor S3.

[0137] In other words, for example, if subject A is exercising, their heart rate will be higher than normal. Therefore, if the abnormality detection unit 420 determines that subject A is exercising based on the acceleration sensor S3, it takes this into account when determining whether subject A's heart rate is abnormal.

[0138] The step count determination unit 330 determines the number of steps taken by subject A based on the information measured by the acceleration sensor S3 and the geomagnetic sensor S4.

[0139] Specifically, the step count determination unit 330 uses the geomagnetic sensor S4 to extract the vertical acceleration value from the acceleration sensor S3 and determines the step count of subject A.

[0140] The blood pressure determination unit 340 estimates and determines the blood pressure of subject A based on the heart rate information measured by the heart rate sensor S2 or the heart rate determined by the heart rate determination unit 320.

[0141] Specifically, blood pressure is calculated by combining the heart rate measurement results (heart rate information) obtained from electrical signals measured by the heart rate sensor S2 and the blood flow measurement results (blood flow information) obtained using an optical sensor (heart rate sensor S2).

[0142] Blood flow measurement (blood flow information) using optical sensors utilizes the mechanism by which blood reflects green light, employing a green light-emitting diode.

[0143] When green light is shone on blood vessels, the way the light reflects differs depending on whether blood flow is high (when the heart is beating) or low. By detecting this difference in reflection, blood flow can be measured (blood flow information).

[0144] If the blood pressure of subject A, as determined by the blood pressure determination unit 340, is outside a predetermined range (for example, if the systolic blood pressure is 100 mmHg or less and the diastolic blood pressure is 60 mmHg or less, or if the systolic blood pressure is 140 mmHg or more and the diastolic blood pressure is 90 mmHg or more), the abnormality determination unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, the second terminal 600 is also notified.

[0145] The blood glucose level determination unit 350 calculates and determines the blood glucose level of subject A based on the information sensed by the blood glucose level sensor S5.

[0146] As we age, sensory functions such as eyesight and hearing, motor functions including muscle strength, and heart and respiratory functions decline. Similarly, insulin secretion from the pancreas also decreases with age.

[0147] Furthermore, as we age, factors such as decreased muscle mass, increased visceral fat, and reduced physical activity make it more difficult to obtain the benefits of insulin in lowering blood sugar, resulting in an increase in the proportion of people with diabetes.

[0148] Furthermore, elderly people with diabetes tend to have elevated blood sugar levels after meals. Also, even when experiencing hypoglycemia, symptoms such as sweating, palpitations, and hand tremors may not appear as readily, and severe hypoglycemia can develop before they take action, such as consuming sugar.

[0149] Hypoglycemia in the elderly can increase the burden of continuing diabetes treatment and lead to a decline in quality of life. Furthermore, severe hypoglycemia can lead to falls, fractures, dementia, and cardiovascular disease.

[0150] As we age, medications tend to accumulate in the body more easily, which can lead to stronger effects, hypoglycemia, and an increased risk of side effects.

[0151] Furthermore, the frequency of developing cerebral infarction, ischemic heart disease, and peripheral artery disease of the lower extremities increases. Therefore, it is preferable for elderly people to continuously monitor their blood glucose levels.

[0152] If the blood glucose level of subject A, as determined by the blood glucose level determination unit 350, is outside the predetermined range, the abnormality detection unit 420 will notify the third terminal 700 via the notification unit 421 or the emergency notification unit 422. This notification will be made if the blood glucose level of subject A is outside the predetermined range (for example, if the early fasting blood glucose level is 126 mg / dl or higher, the 75g OGTT 2-hour value is 200 mg / dl or higher, the random blood glucose level is 200 mg / dl or higher, or the HbA1c (JDS value) is 6.1% or higher). If the emergency notification unit 422 is used, a notification will also be made to the second terminal 600.

[0153] The SpO2 determination unit 360 determines the percutaneous arterial oxygen saturation (SP2) of subject A based on the information sensed by the SpO2 sensor S6.

[0154] In other words, the SpO2 determination unit 360 determines the oxygen concentration in the blood of subject A.

[0155] In sleep apnea syndrome, the oxygen concentration in the blood decreases during periods of apnea, and increases rapidly during breathing.

[0156] The abnormality detection unit 420 determines whether or not subject A may have sleep apnea syndrome based on the oxygen concentration information (changes in oxygen concentration, etc.) determined by the SpO2 detection unit 360.

[0157] If the abnormality detection unit 420 determines that subject A may have sleep apnea syndrome (breathing stops 5 or more times per hour, each time for 10 seconds or more), it notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0158] The sleep determination unit 370 determines the sleep state of subject A based on the heart rate information measured by the heart rate sensor S2 or the heart rate determined by the heart rate determination unit 320, and information about subject A from the acceleration sensor S3.

[0159] In other words, the sleep determination unit 330 determines the "light sleep," "deep sleep," "awake," and "REM sleep" stages of subject A.

[0160] The sleep determination unit 370 can determine the posture of subject A, whether or not they have turned over in their sleep, etc., based on information from the acceleration sensor S3.

[0161] Furthermore, since heart rate decreases during sleep, the sleep detection unit 370 can determine whether or not subject A is sleeping based on heart rate.

[0162] If the abnormality detection unit 420 determines, based on the information from the sleep detection unit 370, that subject A is not getting enough sleep (setting is optional), it notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0163] The sweat determination unit 380 determines the sweating state of subject A based on the information sensed by the sweat sensor S7.

[0164] The sweat detection unit 380 may also make a determination by considering the operating state of subject A, which is sensed by the acceleration sensor S3.

[0165] The abnormality detection unit 420 notifies the third terminal 700 of the subject A's physical condition information via the notification unit 421 or emergency notification unit 422, based on the subject A's sweating information from the sweating detection unit 380, the subject A's movements as detected by the acceleration sensor S3, and the subject A's body temperature information from the body temperature sensor S1 or the body temperature detection unit 310.

[0166] Based on the information sensed by the acceleration sensor S3 and the geomagnetic sensor S4, the fall detection unit 390 determines whether or not subject A has fallen.

[0167] Specifically, if the values ​​sensed by the acceleration sensor S3 and the geomagnetic sensor S4 change rapidly, the fall detection unit 390 determines that subject A has fallen.

[0168] If the fall detection unit 390 determines that subject A has fallen, the abnormality detection unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0169] The stagnation determination unit 400 determines whether or not subject A is stagnating based on the information sensed by the acceleration sensor S3 and the geomagnetic sensor S4.

[0170] If the fall detection unit 390 determines that subject A has fallen, and the stagnation detection unit 400 determines that subject A has been stagnant for a predetermined period of time, the abnormality detection unit 420 will notify the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, the second terminal 600 will also be notified.

[0171] The heatstroke detection unit 410 determines whether subject A is at risk of heatstroke based on the determinations of the body temperature detection unit 310 and the heart rate detection unit 320.

[0172] The abnormality detection unit 420 notifies the second terminal 600 and the third terminal 700 via the communication unit 430.

[0173] The abnormality determination unit 420 determines whether the subject's condition is normal or abnormal. Whether it is normal or abnormal can be set in advance, and the determination is made based on general criteria set in advance by a physician.

[0174] The communication unit 430 includes a notification unit 421 and an emergency notification unit 422. Therefore, the abnormality detection unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, a notification is also sent to the second terminal 600.

[0175] If the abnormality detection unit 420 determines that there is an abnormality in person A and that it is an emergency, it notifies the second terminal 600 and the third terminal 700 via the emergency notification unit 422.

[0176] Even if the abnormality detection unit 420 determines that the subject's condition is normal, information about subject A's condition is always transmitted to the third terminal 700.

[0177] The memory unit 440 stores information from each sensor received from the first terminal 200 and the results determined by each determination unit in the server 300. It also stores personal information of home-care patients, including the elderly.

[0178] The position signal determination unit 450 contains map information. The position signal determination unit 450 reflects the position signal transmitted from the first position signal unit 230 of the first terminal 200 into the map information.

[0179] The location signal of the first terminal 200, reflected in the map information, is transmitted to the second terminal 600 and the third terminal 700. The server 300 may also transmit the location information of the first terminal 200, including the map information, to the second terminal 600 and the third terminal 700.

[0180] If the first terminal 200 moves beyond a predetermined range, the abnormality detection unit 420 notifies the third terminal 700 via the notification unit 421 or the emergency notification unit 422. If the emergency notification unit 422 is used, the second terminal 600 is also notified.

[0181] The WBGT determination unit 460 calculates the WBGT value based on the information sensed by the temperature sensor S8, humidity sensor S9, and black globe temperature sensor S10.

[0182] The black globe temperature sensor S10 detects radiant heat.

[0183] The heatstroke detection unit 410 sends notifications such as "caution" and "warning" to the first terminal 200 and the third terminal 700 based on the WBGT value calculated by the WBGT detection unit 460 and a pre-set value.

[0184] (Terminal 2, 600) As shown in Figure 1, the second terminal 600 is a device such as a smartphone, and an example of its owner is a family member of target person A, such as an elderly person.

[0185] The second terminal 600 includes a second storage unit 610 for storing information, A second communication unit 620 that communicates with the third terminal 700 or the server 300, It includes a second position signal unit 630 that receives a position signal from a position signal determination unit 450.

[0186] The second storage unit 610 stores the information of subject A transmitted from the server 300. However, the system may also be configured without the second storage unit 610.

[0187] The second communication unit 620 communicates with the third terminal 700 or the server 300. Specifically, the second communication unit 620 communicates with the third communication unit 720 of the third terminal 700 or the communication unit 430 of the server 300.

[0188] The second communication unit 620 includes the second emergency receiving unit 621.

[0189] If the abnormality detection unit 420 of server 300 detects an abnormality in owner A of the first terminal 200, the abnormality detection unit 420 notifies the second terminal 600 and the third terminal 700 of this fact via the emergency notification unit 422.

[0190] The second emergency receiving unit 621 of the second terminal 600 receives emergency notifications from the emergency notification unit 422 of the server 300 or the third emergency notification unit 721 of the third terminal 700.

[0191] When the second terminal 600 receives an emergency notification from the emergency notification unit 422 or the third emergency notification unit 721, it notifies the owner of the second terminal 600 that there has been an abnormality with person A via an alarm or the like.

[0192] This allows the owner of the second terminal 600 to immediately ascertain the status of the person A, such as an elderly person being monitored, even when they are away from person A.

[0193] The second position signal unit 630 receives the position signal from the first terminal 200.

[0194] The second position signal unit 630 displays the location of the first terminal 200 on a map displayed on a display unit (not shown), such as a screen.

[0195] This allows the owner of the second terminal 600 to immediately ascertain the location of the person A, such as an elderly person being monitored, even if they are far away from person A.

[0196] Therefore, for example, if subject A is a caregiver for a person with dementia, even if subject A wanders off, the owner of the second terminal 600 can immediately determine subject A's location.

[0197] (Terminal 3, 700) As shown in Figures 1 and 2, when the third terminal 700 receives a notification from the abnormality detection unit 420, it checks the status of subject A, who is the owner of the first terminal 200, performs a diagnosis, and dispatches an ambulance.

[0198] In this embodiment, the owner of the third terminal 700 is a medical institution such as a hospital.

[0199] The third terminal 700 includes a third storage unit 710 that stores information transmitted from the server 300, A third communication unit 720 that communicates with server 300 and second terminal 600, A third position signal unit 730 receives a position signal from the first terminal 200 (or a position signal from the position signal determination unit 450), A diagnostic unit 740 that performs a diagnosis on subject A, who is the owner of the first terminal 200, A dispatch unit 750 dispatches an ambulance or the like to target person A, the owner of the first terminal 200, The second terminal 600 includes a reporting unit 760 that reports the status of subject A, the owner of the first terminal 200, Includes.

[0200] The third communication unit 720 communicates with the server 300 and the second terminal 600, and receives notifications from the abnormality detection unit 420 of the server 300.

[0201] Third Communications Unit 720 is equipped with Third Emergency Communications Unit 721.

[0202] If the abnormality detection unit 420 determines that the content is urgent, the emergency notification unit 422 will send a communication to the third emergency communication unit 721.

[0203] Whether or not a matter is urgent is determined by pre-defined criteria.

[0204] If the abnormality detection unit 420 notifies that "an abnormality has occurred," the third terminal 700 will sound an alarm, illuminate an emergency lamp, or display a message on its screen indicating that an abnormality has occurred with person A.

[0205] If the abnormality detection unit 420 sends a notification from the server 300 to the third terminal 700 indicating that it has determined something is "abnormal", the diagnostic unit 740 performs a diagnosis on subject A at the first terminal 200.

[0206] Furthermore, the diagnostic unit 740 checks the condition of subject A and verifies whether the judgment of the abnormality determination unit 420 is correct.

[0207] The third position signal unit 730 receives the position signal from the first terminal 200 and displays the position of the first terminal 200 on the display screen of the third terminal 700.

[0208] This allows the user of the third terminal 700 to know the location of subject A.

[0209] The diagnostic unit 740 communicates with the first terminal 200 and enables video or audio communication with the first terminal 200.

[0210] In this embodiment, the diagnostic unit 740 is configured to forcibly connect and enable a call even if the user of the first terminal 200 (target person A) does not answer the incoming call.

[0211] The user of the third terminal 700 is a physician or nurse, and can diagnose the user of the first terminal 200 (subject A) via the diagnostic unit 740.

[0212] Furthermore, the diagnostic unit 740 can also be configured to display the other party's video via video call.

[0213] In this embodiment, a surveillance camera is installed, and the diagnostic unit 740 can display the surveillance camera's video feed on the display screen.

[0214] If the diagnostic unit 740 determines that there is no abnormality in subject A, and the physician using the third terminal 700 determines this, the diagnostic information is saved in the diagnostic unit 740.

[0215] Similarly, if the diagnostic unit 740 determines that there is an abnormality in subject A, the physician who is the user of the third terminal 700 will save the diagnosis details in the diagnostic unit 740.

[0216] The diagnostic results from the diagnostic unit 740 are reported from the third terminal 700 to the second terminal 600 by the reporting unit 760.

[0217] If the diagnostic unit 740 determines that there is an abnormality in subject A, and the physician using the third terminal 700 determines that it is an emergency, the dispatch unit 750 will dispatch an ambulance or other vehicle.

[0218] Dispatch Unit 750 is responsible for arranging the dispatch of ambulances and other vehicles.

[0219] If a doctor or nurse who is a user of the third terminal 700 determines that a vehicle is needed for person A, the dispatch unit 750 will dispatch a vehicle.

[0220] The dispatch unit 750 dispatches an ambulance or the like to the location indicated by the position signal of the first terminal 200 via the third position signal unit 730.

[0221] It is preferable that the third terminal 700 be held by multiple people so that any abnormalities in subject A can be reported 24 hours a day.

[0222] In this embodiment, the owner of the third terminal 700 was a welfare officer, but it is also possible that the emergency notification unit 422 automatically contacts the hospital via the third terminal 700.

[0223] Alternatively, an ambulance may be automatically dispatched to the location of person A via the third terminal 700 from the emergency notification unit 422.

[0224] The present invention can also be implemented in various improved, modified, or altered forms without departing from its spirit. [Explanation of Symbols]
