[Effects of the Invention]

[0029] According to the present invention, it is possible to provide a bathroom safety management system and a bathroom safety management method that can manage the safety of a bathroom. [Brief explanation of the drawing]

[0030] [Figure 1] This is a schematic diagram showing a bathroom safety management system according to an embodiment. [Modes for carrying out the invention]

[0031] Embodiments of the present invention are described below. However, these embodiments should not be understood as limiting the present invention. Various alternative embodiments, examples, and operational techniques should become apparent to those skilled in the art from this disclosure. It should be understood that the present invention encompasses various embodiments and the like that are not described herein.

[0032] As shown in Figure 1, the bathroom safety management system according to this embodiment includes a drowning notification data acquisition unit 301 that acquires drowning notification data for a person 10 who has entered the bathtub 101 of 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 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 located near the bathroom 100 or far away from it. The bathroom 100 may be located in residences such as detached houses and apartment buildings, as well as in public facilities such as lodging facilities, dormitories, nursing homes, care facilities, and hospitals.

[0034] The bathroom safety management system according to this embodiment may further include a personal information acquisition unit 314 that acquires personal information of a person 10. For example, a facial recognition device may be installed at the entrance to the changing room of the bathroom 100. The facial recognition device may identify the name of person 10 from the face of person 10 and transmit the personal information of 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 person 10 in a data storage device 303. Alternatively, a personal identification device may be installed in the bathroom 100 that identifies person 10 by detecting the height and build of person 10. The personal identification device may identify the name of person 10 from the height and build of person 10 and transmit the personal information of person 10 to the personal information acquisition unit 314 via a network or the like. Preferably, the personal identification device in the bathroom 100 is a device that enables the identification of person 10 without photographing the naked body of person 10.

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

[0036] The drowning detector 201 may be installed in the bathtub 101. For example, the drowning detector 201 may detect the drowning of a person 10 from a change in the water level in the bathtub 101. Alternatively, the drowning detector 201 may be a wearable device worn by the person 10. The drowning detector 201 may, for example, be equipped with an acceleration sensor and a water pressure sensor, and detect the drowning of the person 10 from the movement of the person 10 and the water pressure. The drowning detector 201 may, for example, be equipped with a heart rate sensor, and detect the drowning of the person 10 based on the heart rate of the person 10. The drowning detector 201 transmits 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 equipped 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 to the bathtub valve 102 via a network or the like to drain the water in the bathtub 101. Upon receiving the drainage instruction data, the bathtub valve 102 opens and drains the water in the bathtub 101. The bathtub valve 102 may be treated to prevent hair from getting entangled in it. Multiple bathtub valves 102 may be provided on the bottom or sides of the bathtub 101. This reduces the possibility of the bathtub valve 102 being blocked by a person 10. If the drowning detection is canceled, or if the rescue of the person 10 is completed, the bathtub valve 102 may be closed.

[0038] An alarm device 107 may be installed in the bathroom 100. 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 an alarm light. For example, if the drowning is due to falling asleep, the alarm can help the person 10 regain consciousness.

[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 may further include 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 person 10. The plurality of rescuers 21A, 21B, 21C... may be family members, nursing home staff, hospital caregivers, nurses, or doctors.

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

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

[0042] The rescue request transmission unit 304 reads data from the data storage device 303 for the rescuer 21A closest to the bathroom 100. For example, rescuers 21A, 21B, 21C, etc. may each have a calling device 207A, 207B, 207C, etc. Examples of calling devices 207A, 207B, 207C, etc. may be mobile phones, PHS phones, and transceivers. The rescue request transmission unit 304 transmits a rescue request for the person 10 drowning 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 confirmation of receipt to the rescue request transmission unit 304. This allows the rescue request transmission unit 304 to cancel the rescue request. If no confirmation of receipt is sent from the rescuer 21A closest to the bathroom 100, the rescue request transmission unit 304 may sequentially send rescue requests to the rescuers in order of proximity to the bathroom 100. If no confirmation of receipt is received after sending rescue requests to a predetermined number of rescuers, the rescue request transmission unit 304 may send a rescue request to all rescuers. Calling devices 207A, 207B, 207C, etc. may be placed in the room where the rescuers 21A, 21B, 21C, etc. are located.

[0044] Furthermore, the rescue request transmission unit 304 may transmit data to, for example, a fire station, hospital, security company, and private ambulance service provider, including the location of the bathroom 100, the fact that person 10 is at risk of drowning, the personal information of person 10, and instructions to transport person 10 to the emergency room.

[0045] The bathroom safety management system according to this embodiment may further include a temperature data acquisition unit 306 for acquiring temperature data of the bathroom 100, and a temperature control unit 307 for controlling the temperature of the bathtub 101 after draining the water from the bathtub 101. The bathroom 100 may also be equipped with, for example, a bathroom thermometer 202 for measuring the temperature of the bathroom 100. Furthermore, the bathroom 100 may also be equipped with, for example, an air conditioning device 203 for adjusting the temperature of the bathroom 100.

[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 has transmitted the drainage instruction data, and transmits temperature control instruction data to the air conditioning unit 203 via a network or the like so that the temperature inside the bathroom 100 is at a temperature that can sustain the life of a naked person 10 in the bathtub 101. The air conditioning unit 203 receives the temperature control instruction data and adjusts the temperature inside 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 to notify a person 10 of a fall. The bathroom safety management system according to the embodiment may further include a shower stop instruction unit 309 that transmits shower stop instruction data to stop the shower 103 in the bathroom 100 when the fall notification data acquisition unit 308 acquires fall notification data. The bathroom 100 may be equipped with, for example, a fall detector 204 that detects a person 10 falling. The bathroom 100 may also be equipped with, for example, a supply valve 104 that controls the supply of water to the shower 103.

[0048] For example, the fall detector 204 may detect the movement of person 10 using an ultrasonic sensor, a radio wave sensor such as a millimeter wave or microwave sensor, or an infrared sensor, and detect when person 10 falls. Alternatively, the drowning detector 201 may detect the breathing and heart rate of person 10 and detect when person 10 falls. Alternatively, the fall detector 204 may be a wearable device and be worn by person 10. The fall detector 204 may, for example, be equipped with an acceleration sensor and detect when person 10 falls from the movement of person 10. The drowning detector 201 may, for example, be equipped with a heart rate sensor and detect when person 10 falls based on the heart rate of person 10. After determining that a fall has occurred, if it is determined that person 10's posture and position are normal, the determination that person 10 has fallen may be canceled.

[0049] The bathroom 100 may be equipped with a notification signal output device 106 that outputs a notification signal. The notification signal output device 106 may, for example, output a display and a speaker. The notification signal output device 106 may prompt the person 10 to speak about their condition. If the person 10 says that they have not fallen, the determination that the person 10 has fallen may be canceled.

[0050] When the fall detection device 204 detects that a person 10 has fallen, 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 has acquired 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. Upon receiving the shower stop instruction data, the supply valve 104 closes, stopping the discharge of water from the shower 103. This prevents the discharge of water from accelerating bleeding of the person 10. If the fall detection is canceled, or if the rescue of the person 10 is completed, the discharge of water from the shower 103 may be resumed.

[0051] When the fall notification data acquisition unit 308 acquires fall notification data, the rescue request transmission unit 304 may send a rescue request for the person 10 who has fallen in the bathroom 100 to the call device 207A of the rescuer 21A closest to the bathroom 100. If the rescuer 21A closest to the bathroom 100 does not send a confirmation of receipt, the rescue request transmission unit 304 may sequentially send rescue requests to rescuers in order of proximity to the bathroom 100. If no confirmation of receipt is received after sending rescue requests to a predetermined number of rescuers, the rescue request transmission unit 304 may send a rescue request to all rescuers. The rescue request transmission unit 304 may also send data to, for example, a fire station, hospital, security company, and private ambulance service provider, including the location of the bathroom 100, the possibility that person 10 has fallen, the personal information of person 10, and instructions to transport person 10 by ambulance. A transmitter for person 10 to send a rescue request themselves may be installed 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 shower stop instruction data, and transmits temperature control instruction data to the air conditioning unit 203 via a network or the like so that the temperature inside the bathroom 100 is at a level that can sustain the life of a naked person 10 inside the bathroom 100. The air conditioning unit 203 receives the temperature control instruction data and adjusts the temperature inside the bathroom 100 according to the temperature control instruction data.

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

[0054] The bathroom safety management system according to this 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 greater than or equal to a threshold. 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 a data storage device 303. Furthermore, 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 greater than or equal to a predetermined threshold. If the temperature difference is greater than or equal to the threshold, the temperature control unit 307 transmits temperature control instruction data to the air conditioning unit 203 via a network or the like to raise the temperature of the bathroom so that a person 10 in the bathroom 100 does not suffer heat shock. The predetermined threshold is arbitrary, but for example it is 10°C. The predetermined threshold can be set arbitrarily. The air conditioning unit 203 receives the temperature control instruction data and adjusts the temperature in the bathroom 100 according to the temperature control instruction data.

[0055] The bathroom safety management system according to this embodiment may further include a notification signal transmitting unit 311 that transmits a temperature difference notification signal to notify that the temperature difference is above a threshold 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 above a threshold. The notification signal transmitting unit 311 transmits the temperature difference notification signal to the notification signal output device 106, for example, via a network. The notification signal output device 106 outputs the received temperature difference notification signal. This alerts the person 10 to the risk of heat shock. Furthermore, if 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 falls below a threshold, the notification signal transmitting unit 311 may transmit a temperature difference notification signal to the notification signal transmitting unit 311, for example, via a network, to notify that the temperature difference is below a threshold. This notifies the person 10 that the risk of heat shock has been eliminated.

[0056] The bathroom safety management system according to this 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 a normal range. For example, a vital data measuring device 205 is installed in the bathroom 100 to measure the vital data of a person 10. The vital data may be, for example, heart rate and respiration. For example, a drowning detector 201 acquires the vital data of a person 10 using an ultrasonic sensor, a radio wave sensor such as a millimeter wave or microwave, or an infrared sensor. The vital data measuring device 205 may be installed in the bathtub 101. Alternatively, the vital data measuring device 205 may be a wearable terminal worn by the person 10.

[0057] The vital data measuring 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 the vital data of person 10 from the data storage device 303, for example. Furthermore, the vital data determination unit 313 determines whether or not the vital data of person 10 is within the normal range. The normal range of person 10's vital data may be the average value of previously acquired vital data of person 10. The normal range of person 10's vital data may be set according to cardiovascular guidelines. The normal range of person 10's vital data may be updated based on the vital data of person 10 when they drowned or fell. The vital data determination unit 313 may also determine from the vital data whether or not person 10 has been drinking alcohol.

[0058] If the vital data determination unit 313 determines that the vital data of person 10 is outside the normal range, the rescue request transmission unit 304 may send a signal to the call device 207A of the rescuer 21A closest to the bathroom 100 notifying them that the vital data of person 10 is outside the normal range. If the rescuer 21A closest to the bathroom 100 does not send a confirmation of receipt, the rescue request transmission unit 304 may sequentially send rescue requests to rescuers in order of proximity to the bathroom 100. If no confirmation of receipt is received after sending rescue requests to a predetermined number of rescuers, the rescue request transmission unit 304 may send a rescue request to all rescuers. The rescue request transmission unit 304 may also send data to, for example, a fire station, hospital, security company, and private ambulance service provider, including the location of the bathroom 100, that the vital data of person 10 is outside the normal range, the personal information of person 10, and instructions to transport person 10 by ambulance.

[0059] The notification signal transmission unit 311 may, for example, transmit a signal to the notification signal output device 106 via a network or the like that notifies that the vital data of person 10 is outside the normal range. The notification signal output device 106 outputs a signal that notifies that the received vital data of person 10 is outside the normal range. This makes it possible to notify person 10 that their vital data is outside the normal range and to draw their attention to the situation.

[0060] According to the bathroom safety management system of the embodiment described above, it is possible to manage the safety of people in the bathroom and to rescue them quickly in the event of drowning or falling.
