The notification unit 34, the body temperature reporting unit 35, and the determination reporting unit 36 are realized when the CPU reads out and executes a program stored in the external storage device.

Hereinafter, first, the detection apparatus 2 will be described.
The bed human sensor 21 is an ultrasonic sensor that detects whether a human body is in a predetermined range on the bed 71 by transmitting ultrasonic waves and detecting reflection of the transmitted ultrasonic waves. That is, when the cared person 70 raises his / her upper body on the bed 71, the head or upper body of the cared person 70 is detected by the bed person sensor 21.

  FIG. 4 is a side view showing a range detected by the bed human sensor 21 by a hatched region 55, and FIG. 5 is a plan view showing the same range by a hatched region 56. As shown in FIGS. 4 and 5, the bed sensor 21 detects the upper body when the cared person gets up on the bed 71, and in the state where the person is lying on the bed 71, for example, turns over. It is set to detect a range of height that will not be detected even when hit. For example, if the cared person 70 is about 165 cm tall, it is set to detect a range of 60 cm to 70 cm on the surface of the bed 71 and a distance from the head side of the bed 71 of 30 cm to 150 cm. . Note that the range detected by the bed human sensor 21 can be adjusted according to the body shape of the care receiver 70 by adjusting the angle adjusting bracket 45 and the height adjusting bracket 46.

  The on-floor human sensor 22 is an ultrasonic sensor that detects whether a human body is in a predetermined range on the floor surface beside the bed 71 by transmitting an ultrasonic wave and detecting reflection of the transmitted ultrasonic wave. is there. That is, when the cared person 70 leaves the bed 71 or falls, the on-floor human sensor 22 detects the cared person 70 who has fallen.

FIG. 6 is a side view showing a range detected by the human sensor 22 on the floor by a hatched area 57, and FIG. 7 is a plan view showing the same area by a hatched area 58. As shown in FIG. As shown in FIGS. 6 and 7, the on-floor human sensor 22 has a predetermined distance (for example, 10 cm or more and 50 cm or less) from the left and right side surfaces of the bed 71 and a predetermined height on the floor surface from the floor surface. The presence or absence of a human body is detected in a range up to (for example, 30 cm).
The bed human sensor 21 and the floor human sensor 22 are not limited to ultrasonic sensors, and may be any sensor that can detect a human body, such as an infrared sensor that detects infrared radiation emitted from the human body.
The temperature sensor 23 is a sensor that detects the temperature of the cared person 70 by detecting infrared rays emitted from the cared person 70.

  The sound collecting microphone 24 is a microphone that detects sound in the bedroom of the care receiver 70. For example, when the cared person 70 falls from the bed 71 or when his condition deteriorates, he / she often asks for help or whispers. Can be detected.

  The command input unit 25 is configured by, for example, a push button provided in the detection device 2, and receives a command input to stop / activate determination processing by the determination unit 31 of the management device 3. For example, each time the push button is pressed, the execution state and the stop state of the determination process by the determination unit 31 may be switched, or a stop command input button and an operation command input button are provided separately. Also good. When a stop command is input from the command input unit 25, a determination process (details will be described later) performed by the determination unit 31 based on detection signals from the bed human sensor 21 and the floor human sensor 22 is stopped, and an operation command is issued. When the input is made, the determination process is started. Thereby, when a care worker, a visitor, etc. approach the cared person 70, it can prevent determining this care worker etc. as an operation | movement of a cared person.

  Note that the command input unit 25 may be input by a remote controller. That is, a caregiver carries a remote controller, inputs a stop command by the remote controller when approaching the cared person 70 for nursing care, etc., and issues an operation command when the care is finished and leaves the cared person 70. You may make it input.

  In addition, the command input unit 25 may be an IC tag reader that is installed in the vicinity of the entrance / exit of the room where the care receiver 70 is located and is connected to the detection device 2 so as to be communicable. A care worker or a visitor carries an IC tag in which unique identification information is stored, and the IC tag reader is transmitted from the IC tag when the care worker enters or leaves the room where the care recipient 70 is located. A stop command or an operation command is received by receiving a signal including identification information. That is, when a signal including identification information is received for the first time, it can be determined that a care worker corresponding to the identification information has entered the room, and when a signal including the same identification information is received for the second time, the corresponding care worker It can be determined that the person has left the room. In this manner, the number of persons in charge of caregivers, visitors, etc. existing in the room can be grasped by the entry / exit of the person detected based on the signal received by the IC tag reader from the IC tag. A stop command is input when a caregiver or a visitor is present in the room, and an activation command is entered when no caregiver or a visitor is present in the room. Thus, the command input unit 25 can be configured.

In the state display unit 26, the bed leaving detection system 1 is currently in a state where the operation of the determination unit 31 is stopped by the stop command received by the command input unit 25, or the determination unit 31 is operating. Displays whether it is in a state.
The video camera 27 photographs the care receiver 70 on the bed 71.
The transmission unit 28 assigns the detection signal of the bed human sensor 21, the floor human sensor 22, the temperature sensor 23, and the sound collecting microphone 24 and the stop / operation command input to the command input unit 25 to the detection device 2. The identification information is transmitted to the management apparatus 3 via the communication line 47.

Next, the management apparatus 3 will be described.
In FIG. 8, an example of the front external appearance of the management apparatus 3 is shown. In the example shown in the figure, a display unit 32 such as a liquid crystal display and a speaker 33 are provided on the front panel of the management device 3. In the following description, display at the time of abnormality determination is performed on the display unit 32, and an abnormality warning sound is output from the speaker 33. However, the present invention is not limited thereto, and the lamp and buzzer are respectively displayed on the display unit 32 and the speaker 33. It may be provided separately.
Referring back to FIG. 3, the receiving unit 30 receives information transmitted from the transmitting unit 28 via the communication line 47.

The determination unit 31 determines the state of the care recipient 70 based on the information received by the reception unit 30. Specifically, when the operation command is input to the command input unit 25 and the couch human sensor 21 detects a human body on the couch 71, it is determined that the care receiver 70 has risen on the couch 71. To do.
In addition, when the operation command is input to the command input unit 25, the determination unit 31 does not detect the presence of the human body in the predetermined range on the bed 71 and the on-floor human sensor 22. When the human body is detected on the floor next to the bed 71, it is determined that the care receiver 70 has fallen from the bed 71.
Furthermore, when the body temperature of the cared person 70 detected by the temperature sensor 23 is outside the range of normal heat (for example, 35.0 ° C. to 36.0 ° C.), the determination unit 31 has an abnormality in the cared person 70. Judge that there is.

  When the determination unit 31 determines that the care receiver 70 is in a predetermined state (a state where the care receiver 70 is awaken on the bed 71, a state where the caregiver 71 falls from the bed 71, or some other abnormality occurs), The determination unit 31 displays the abnormal state together with the identification information (name, etc.) of the corresponding cared person 70 specified with reference to the identification information storage unit 37. That is, the identification information storage unit 37 includes identification information of each detection device 2, identification information of the care receiver 70 of the bed on which the detection device 2 is installed (for example, a room number and a name or a care receiver number). Are stored, and the determination unit 31 identifies the care receiver 70 in which the abnormality is determined with reference to the above-described correspondence relationship based on the identification information of the detection device 2 transmitted from the detection device 2. Then, as shown in FIG. 9, the identification information of the care receiver 70 and the abnormal state are displayed. In the display example shown in FIG. 9, it is displayed that Mr. B in the A room gets up on the bed 71.

  The display unit 32 displays the body temperature of the cared person 70 detected by the temperature sensor 23 and displays the image of the cared person 70 taken by the video camera 27. Further, the video storage unit 40 stores video information of the cared person 70 taken by the video camera 27, and the display unit 32 is stored in the video storage unit 40 when the determination unit 31 determines abnormality. Based on the video information, the video of the care recipient 70 from a predetermined time (for example, 30 seconds) before the determination to the determination is displayed. Also in these cases, as described above, the care recipient is specified based on the identification information of the detection device 2 transmitted from the detection device 2, and the body temperature and the video are displayed together with the identification information of the care recipient. In addition, an input unit for designating a care recipient to be monitored may be provided in the management device 3 so that information on the designated care recipient is displayed, or each care recipient can be switched sequentially. Information may be displayed.

  The speaker 33 outputs the sound detected by the sound collection microphone 24. For example, when the cared person 70 raises a voice for calling a care worker or a voice for help, the speaker 33 outputs the voice.

  When the notification unit 34 determines in the determination unit 31 that the care recipient 70 is in a predetermined state (a state of getting up on the bed 71, a state of falling from the bed 71, or any other abnormality), The state is notified to the terminal carried by the caregiver of the care receiver 70. Moreover, when the determination part 31 determines that the body temperature of the care receiver 70 is abnormal, the notification part 34 notifies the terminal carried by the care worker. In addition, about the body temperature of the care receiver 70 detected by the temperature sensor 23, the care receiver may be notified of the body temperature at all times.

  In addition, a voice storage unit (not shown) that stores a fallen sound of a care recipient, a moaning voice, a voice for helping, and the like is provided, and the determination unit 31 uses the voice information detected by the sound collecting microphone 24 as the voice storage. When the sound information matches the sound information stored in the unit, it may be determined that an abnormality has occurred in the care recipient. Further, when a silent state in which no sound is detected by the sound collecting microphone 24 continues for a certain period or longer, it may be determined that some abnormality has occurred in the care recipient.

  The body temperature reporting unit 35 transmits the body temperature information received by the receiving unit 30 such as the body temperature of the cared person detected by the temperature sensor 23 to a predetermined destination registered in advance, such as a relative. In addition, the determination report unit 36 transmits the result determined by the determination unit 31, body temperature information, and the like to a predetermined destination registered in advance, such as a relative. In other words, the contact storage unit 41 stores the identification information of each cared person and the mail address of the contact person (for example, family or relative) about the cared person in association with each other, and the body temperature reporting unit 35 And the judgment report part 36 transmits the said judgment result, body temperature information, etc. to the mail address acquired with reference to this contact address memory | storage part 41. FIG.

The wake-up cared person storage unit 38 requires attention to a cared person who has been detected to have risen by the bed human sensor 21 for a predetermined number of times (for example, 10 times) or more in a predetermined period (for example, one day). Remember me as an important care recipient. In addition, the fall care receiver storage unit 39 detects that the floor human sensor 22 has left the bed 71 or has fallen for a predetermined number of times (for example, five months) or more in a predetermined period (for example, one month). The care recipient is memorized as an important care recipient requiring attention. The caregiver can identify the care recipient who should be given care mainly by referring to the care receiver stored in the wake-up caregiver storage unit 38 and the fall caregiver storage unit 39.
The video storage unit 40 stores video information captured by the video camera 27 transmitted from the detection device 2.
