Mode for Carrying Out the Invention

[0031] Embodiments of the present invention will be described below. However, it should not be understood that the following embodiments limit the present invention. Various alternative embodiments, examples, and operation techniques should be apparent to those skilled in the art from this disclosure. It should be understood that the present invention encompasses various embodiments not described herein.

[0032] As shown in FIG. 1, a bathroom safety management system according to an embodiment includes a drowning notification data acquisition unit 301 that acquires drowning notification data for notifying drowning of a person 10 who has entered the bathtub 101 in the bathroom 100, and a drainage instruction unit 302 that transmits drainage instruction data for draining the water in the bathtub 101 when the drowning notification data acquisition unit 301 acquires the drowning notification data. The drowning notification data acquisition unit 301 and the drainage instruction unit 302 are included in, for example, a computer system 300.

[0033] The computer system 300 may be arranged near or far from the bathroom 100. The bathroom 100 may be, for example, a residence such as a detached house or an apartment house, as well as a public facility such as an accommodation facility, a dormitory, a nursing home, a care facility, and a hospital.

[0034] The bathroom safety management system according to the embodiment may further include a personal information acquisition unit 314 that acquires personal information of the person 10. For example, a face recognition device may be provided at the entrance of the dressing room in the bathroom 100. The face recognition device may identify the name of the person 10 from the face of the person 10 and transmit the personal information of the person 10 to the personal information acquisition unit 314 via a network or the like. The personal information acquisition unit 314 stores the received personal information of the person 10 in the data storage device 303. Alternatively, a personal identification device for identifying the person 10 by detecting the height and physique of the person 10 may be provided in the bathroom 100. The personal identification device may identify the name of the person 10 from the height and physique of the person 10 and transmit the personal information of the person 10 to the personal information acquisition unit 314 via a network or the like. The personal identification device in the bathroom 100 is preferably a device that can identify the person 10 without photographing the naked body of the person 10.

[0035] For example, in the bathroom 100, a drowning detector 201 for detecting that a person 10 has drowned in the water in the bathtub 101 is installed. The water includes cold water and hot water, and the temperature of the water is not limited. The method by which the drowning detector 201 detects the drowning of the person 10 is not particularly limited. For example, the drowning detector 201 may detect the position of the head of the person 10 by an ultrasonic sensor, a radio wave sensor such as a millimeter wave or a microwave, or an infrared sensor, and if the position of the head is lower than the water surface for a predetermined time, it may be determined that the person 10 is drowning. Alternatively, the drowning detector 201 may detect the breathing and heartbeat of a person and detect the drowning of the person 10. In addition, if it is determined that the person 10 is not drowning from the movement of the person 10 after a predetermined time, the drowning detector 201 may cancel the determination that the person 10 has drowned.

[0036] The drowning detector 201 may be provided in the bathtub 101. For example, the drowning detector 201 may detect the drowning of the person 10 from the change in the water level of the water in the bathtub 101. Alternatively, the drowning detector 201 is a wearable terminal and may be worn by the person 10. The drowning detector 201 may include, for example, an acceleration sensor and a water pressure sensor, and may detect the drowning of the person 10 from the movement of the person 10 and the water pressure. The drowning detector 201 may include, for example, a heartbeat sensor and may detect the drowning of the person 10 based on the heartbeat of the person 10. The drowning detector 201 transmits the drowning notification data to the drowning notification data acquisition unit 301 via a network or the like. The drowning notification data acquisition unit 301 stores the received drowning notification data in the data storage device 303.

[0037] The bathtub 101 is provided with a bathtub valve 102. When the drowning notification data acquisition unit 301 acquires drowning notification data, the drainage instruction unit 302 transmits drainage instruction data for draining the water in the bathtub 101 to the bathtub valve 102 via a network or the like. The bathtub valve 102 that has received the drainage instruction data opens and drains the water in the bathtub 101. The bathtub valve 102 may be processed so that hair does not get wrapped around it. A plurality of bathtub valves 102 may be provided on the bottom or side surface of the bathtub 101. Thereby, it is possible to reduce the possibility that the bathtub valve 102 is blocked by the human 10. When the determination of drowning is canceled or when the rescue of the human 10 is completed, the bathtub valve 102 may be closed.

[0038] The bathroom 100 may be provided with an alarm device 107. When the drowning notification data acquisition unit 301 acquires drowning notification data, the drowning notification data acquisition unit 301 instructs the alarm device 107 to issue an alarm via a network or the like. The alarm device 107 emits an alarm sound or alarm light. For example, when drowning is due to dozing off, it is possible for the human 10 to regain consciousness by the alarm.

[0039] The bathroom safety management system according to the embodiment may further include a rescue request transmission unit 304 that transmits a rescue request when the drowning notification data acquisition unit 301 acquires drowning notification data. For example, the bathroom safety management system according to the embodiment further includes a rescuer data acquisition unit 305 that acquires data of the rescuer 21A closest to the bathroom 100 among a plurality of rescuers 21A, 21B, 21C, ···, and the rescue request transmission unit 304 may transmit a rescue request to the rescuer 21A closest to the bathroom 100. The rescue request transmission unit 304 may transmit personal information of the human 10. The plurality of rescuers 21A, 21B, 21C, ··· may be family members, staff of a nursing home, nurses or doctors in a hospital.

[0040] For example, rescuers 21A, 21B, 21C, etc. may each have a position information transmitter 202A, 202B, 202C, etc. The position information transmitters 202A, 202B, 202C, etc. measure the respective positions of the rescuers 21A, 21B, 21C, etc. by a positioning system such as a Global Positioning System (GPS), and transmit the positions to the rescuer data acquisition unit 305 via a network or the like. Alternatively, the position information transmitters 202A, 202B, 202C, etc. may be beacons. The rescuer data acquisition unit 305 stores the received data of the respective positions of the rescuers 21A, 21B, 21C, etc. in the data storage device 303.

[0041] The rescuer data acquisition unit 305 compares the received data of the respective positions of the rescuers 21A, 21B, 21C, etc., sorts the rescuers 21A, 21B, 21C, etc. according to the distance from the bathroom 100, and acquires the data of the rescuer 21A closest to the bathroom 100. The rescuer data acquisition unit 305 stores the acquired data of the rescuer 21A closest to the bathroom 100 and the sorted data of the rescuers 21A, 21B, 21C, etc. in the data storage device 303.

[0042] The rescue request transmission unit 304 reads out the data of the rescuer 21A closest to the bathroom 100 from the data storage device 303. For example, the rescuers 21A, 21B, 21C, etc. may each have a calling device 207A, 207B, 207C, etc. As the calling devices 207A, 207B, 207C, etc., for example, mobile phones, PHSs, and transceivers can be used. The rescue request transmission unit 304 transmits a rescue request for the person 10 who has drowned in the bathroom 100 to the calling device 207A of the rescuer 21A closest to the bathroom 100. The rescue request may be a short message or an email.

[0043] The rescuer 21A closest to the bathroom 100 may send a reception confirmation to the rescue request transmission unit 304. Thereby, the rescue request transmission unit 304 may cancel the rescue request. When a reception confirmation is not sent from the rescuer 21A closest to the bathroom 100, the rescue request transmission unit 304 may sequentially send a rescue request to the rescuers in ascending order of the distance from the bathroom 100. When there is no reception confirmation even after sending a rescue request to a predetermined number of rescuers, the rescue request transmission unit 304 may send a rescue request to all the rescuers. The calling devices 207A, 207B, 207C... may be arranged in the rooms where the rescuers 21A, 21B, 21C... are located.

[0044] In addition, the rescue request transmission unit 304 may transmit data including the location of the bathroom 100, the possibility that the person 10 may be drowning, the personal information of the person 10, and an instruction to perform emergency transportation of the person 10 to, for example, a fire department, a hospital, a security company, and a private emergency service provider company.

[0045] The bathroom safety management system according to the embodiment may further include a temperature data acquisition unit 306 that acquires temperature data of the bathroom 100, and a temperature control unit 307 that controls the temperature of the bathtub 101 after draining the water in the bathtub 101. In the bathroom 100, for example, a bathroom thermometer 202 for measuring the temperature of the bathroom 100 may be provided. Also, in the bathroom 100, for example, an air conditioner 203 for adjusting the temperature of the bathroom 100 may be provided.

[0046] The bathroom thermometer 202 transmits the measured temperature data of the bathroom 100 to the temperature data acquisition unit 306 via a network or the like. The temperature data acquisition unit 306 stores the received temperature data of the bathroom 100 in the data storage device 303. The temperature control unit 307 monitors the temperature of the bathroom 100 after the drainage instruction unit 302 transmits drainage instruction data, and transmits temperature control instruction data to the air conditioner 203 via a network or the like so that the temperature in the bathroom 100 becomes a temperature at which the naked person 10 in the bathtub 101 can maintain life. The air conditioner 203 receives the temperature control instruction data and adjusts the temperature in the bathroom 100 according to the temperature control instruction data.

[0047] The bathroom safety management system according to the embodiment may further include a fall notification data acquisition unit 308 that acquires fall notification data for notifying a fall of a person 10. Further, the bathroom safety management system according to the embodiment may further include a shower stop instruction unit 309 that transmits shower stop instruction data for stopping the shower 103 in the bathroom 100 when the fall notification data acquisition unit 308 acquires the fall notification data. In the bathroom 100, for example, a fall detector 204 for detecting a fall of a person 10 may be provided. Further, in the bathroom 100, for example, a supply valve 104 for controlling the supply of water to the shower 103 may be provided.

[0048] For example, the fall detector 204 may detect the movement of the person 10 by an ultrasonic sensor, a radio wave sensor such as millimeter wave or microwave, or an infrared sensor, and detect the fall of the person 10. Alternatively, the drowning detector 201 may detect the respiration and heartbeat of a person and detect the fall of the person 10. Further alternatively, the fall detector 204 may be a wearable terminal and may be worn by the person 10. The fall detector 204 may include, for example, an acceleration sensor and detect the fall of the person 10 from the movement of the person 10. The drowning detector 201 may include, for example, a heartbeat sensor and detect the fall of the person 10 based on the heartbeat of the person 10. After determining a fall, if it is determined that the posture and body position of the person 10 are normal, the determination that the person 10 has fallen may be canceled.

[0049] In the bathroom 100, a notification signal output device 106 that outputs a notification signal may be provided. As the notification signal output device 106, for example, a display and a speaker can output. The notification signal output device 106 may prompt the person 10 to speak their own state. If the person 10 speaks that they have not fallen, the determination that the person 10 has fallen may be canceled.

[0050] When the fall detector 204 detects the fall of the human 10, it transmits fall notification data to the fall notification data acquisition unit 308 via a network or the like. The fall notification data acquisition unit 308 stores the received fall notification data in the data storage device 303. When the fall notification data acquisition unit 308 acquires the fall notification data, the shower stop instruction unit 309 transmits shower stop instruction data to the supply valve 104 via a network or the like. The supply valve 104 that has received the shower stop instruction data closes, stopping the water discharge from the shower 103. Thereby, it is possible to prevent the bleeding of the human 10 from being promoted by the water discharge. When the determination of the fall is canceled, or when the rescue of the human 10 is completed, the water discharge from the shower 103 may be restarted.

[0051] When the fall notification data acquisition unit 308 acquires the fall notification data, the rescue request transmission unit 304 may transmit a rescue request for the human 10 who has fallen in the bathroom 100 to the calling device 207A of the rescuer 21A closest to the bathroom 100. If a reception confirmation is not transmitted from the rescuer 21A closest to the bathroom 100, the rescue request transmission unit 304 may sequentially transmit a rescue request to the rescuers in ascending order of the distance from the bathroom 100. If there is no reception confirmation even after transmitting a rescue request to a predetermined number of rescuers, the rescue request transmission unit 304 may transmit a rescue request to all the rescuers. Further, the rescue request transmission unit 304 may transmit data including the location of the bathroom 100, the possibility that the human 10 may have fallen, the personal information of the human 10, and an instruction to transport the human 10 to the emergency to, for example, the fire department, the hospital, the security company, and the private emergency service providing company. A transmitter for the human 10 to transmit a rescue request by himself / herself may be arranged in the bathroom 100.

[0052] The temperature control unit 307 monitors the temperature of the bathroom 100 after the shower stop instruction unit 309 transmits the shower stop instruction data, and transmits temperature control instruction data to the air conditioner 203 via a network or the like so that the temperature in the bathroom 100 becomes a temperature at which the naked human 10 in the bathroom 100 can maintain life. The air conditioner 203 receives the temperature control instruction data and adjusts the temperature in the bathroom 100 according to the temperature control instruction data.

[0053] The bathroom 100 may be provided with, for example, a bathtub thermometer 105 for measuring the temperature of the water in the bathtub 101. The bathtub thermometer 105 may be provided in the water heater. The bathtub thermometer 105 transmits data on the temperature of the water in the bathtub 101 measured via a network or the like to the temperature data acquisition unit 306. The temperature data acquisition unit 306 stores the received data on the temperature of the water in the bathtub 101 in the data storage device 303.

[0054] The bathroom safety management system according to the embodiment may further include a temperature difference determination unit 310 that determines whether the temperature difference between the temperature of the bathroom 100 and the temperature of the water in the bathtub 101 is equal to or greater than a threshold value. The temperature difference determination unit 310 reads, for example, the temperature of the bathroom 100 and the temperature of the water in the bathtub 101 from the data storage device 303. Further, the temperature difference determination unit 310 calculates the temperature difference between the temperature of the bathroom 100 and the temperature of the water in the bathtub 101, and determines whether the temperature difference is equal to or greater than a predetermined threshold value. When the temperature difference is equal to or greater than the threshold value, the temperature control unit 307 transmits temperature control instruction data for raising the temperature of the bathroom via a network or the like to the air conditioner 203 so that no heat shock occurs to the person 10 in the bathroom 100. The predetermined threshold value is arbitrary, for example, 10°C. The predetermined threshold value can be arbitrarily set. The air conditioner 203 receives the temperature control instruction data and adjusts the temperature in the bathroom 100 according to the temperature control instruction data.

[0055] In the bathroom safety management system according to the embodiment, when the temperature difference determination unit 310 determines that the temperature difference between the temperature of the bathroom 100 and the temperature of the water in the bathtub 101 is equal to or greater than the threshold value, the notification signal transmission unit 311 that transmits a temperature difference notification signal for notifying that the temperature difference is equal to or greater than the threshold value may be further provided. The notification signal transmission unit 311 transmits the temperature difference notification signal to the notification signal output device 106 via, for example, a network or the like. The notification signal output device 106 outputs the received temperature difference notification signal. Thereby, the person 10 is alerted to the risk of heat shock. Further, when the temperature control unit 307 raises the temperature of the bathroom and the temperature difference between the temperature of the bathroom 100 and the temperature of the water in the bathtub 101 becomes less than the threshold value, the notification signal transmission unit 311 may transmit, via, for example, a network or the like, a temperature difference notification signal for notifying that the temperature difference is less than the threshold value to the notification signal transmission unit 311. Thereby, the person 10 is notified that the risk of heat shock has been eliminated.

[0056] The bathroom safety management system according to the embodiment may further include a vital data acquisition unit 312 that acquires human vital data, and a vital data determination unit 313 that determines whether the vital data is within the normal range. For example, in the bathroom 100, a vital data measurement device 205 that measures human vital data is installed. The vital data is, for example, heartbeat and respiration. For example, the drowning detector 201 acquires human vital data by an ultrasonic sensor, a radio wave sensor such as millimeter wave or microwave, or an infrared sensor. The vital data measurement device 205 may be provided in the bathtub 101. Alternatively, the vital data measurement device 205 may be a wearable terminal and may be worn by the person 10.

[0057] The vital data measurement device 205 transmits vital data to the vital data acquisition unit 312 via a network or the like. The vital data acquisition unit 312 stores the received vital data in the data storage device 303. The vital data determination unit 313 reads out, for example, the vital data of the human 10 from the data storage device 303. Further, the vital data determination unit 313 determines whether the vital data of the human 10 is within the normal range. The normal range of the vital data of the human 10 may be the average value of the previously acquired vital data of the human 10. The normal range of the vital data of the human 10 may be set according to the guidelines of the cardiovascular system. The normal range of the vital data of the human 10 may be updated based on the vital data when the human 10 drowns or falls. The vital data determination unit 313 may determine whether the human 10 is after drinking alcohol from the vital data.

[0058] When the vital data determination unit 313 determines that the vital data of the human 10 is outside the normal range, the rescue request transmission unit 304 may transmit a signal notifying that the vital data of the human 10 is outside the normal range to the calling device 207A of the rescuer 21A closest to the bathroom 100. If no reception confirmation is transmitted from the rescuer 21A closest to the bathroom 100, the rescue request transmission unit 304 may sequentially transmit a rescue request to the rescuers in ascending order of the distance from the bathroom 100. If no reception confirmation is received even after transmitting a rescue request to a predetermined number of rescuers, the rescue request transmission unit 304 may transmit a rescue request to all the rescuers. Further, the rescue request transmission unit 304 may transmit data including the location of the bathroom 100, the fact that the vital data of the human 10 is outside the normal range, the personal information of the human 10, and an instruction to urgently transport the human 10 to, for example, the fire department, the hospital, the security company, and the private emergency service provider company.

[0059] The notification signal transmission unit 311 may transmit, for example, a signal notifying that the vital data of the human 10 is outside the normal range to the notification signal output device 106 via a network or the like. The notification signal output device 106 outputs a signal notifying that the received vital data of the human 10 is outside the normal range. Thereby, it is possible to notify the human 10 that the vital data is outside the normal range and to arouse attention.
