Description

  The present invention relates to an electronic nurse call device, for example, an electronic nurse call device that detects a patient's rising and makes a nurse call.

  In the care field, a nurse call system is often used for communication between a care recipient and a caregiver. For example, when getting up from a bed, an accident such as a fall is likely to occur. In such a case, the care recipient may call the caregiver using a nurse call.

  Therefore, many nurse call systems have been proposed in order to reduce the burden on the user. For example, Patent Document 1 includes a stop button for instructing stoppage of a call or alarm, and a control unit that controls an operation related to stop / recovery of output of the call or alarm, from the time when the stop button is operated By controlling to stop the call or alarm output for a predetermined time, if the nurse performs a treatment after pressing the stop button, even if the nurse call slave unit sensor is inadvertently activated during the treatment, Disclosed is a false alarm prevention device that prevents a call or alarm from being output, and automatically restores the call or alarm output when a predetermined time has elapsed since the stop button was operated. Has been. According to the false alarm prevention device described in Patent Document 1, it is possible to stop the output of a call or an alarm during a nurse's treatment, and the nurse does not perform a troublesome operation after the treatment is completed. It is possible to reliably restore the call and alarm output.

  However, in the technique described in Patent Document 1, a call or alarm (hereinafter referred to as a call or the like) can be stopped only for a predetermined time that is set in advance, and care takes longer than planned. Cannot prevent a call or the like from being mistakenly performed. Further, in the technique described in Patent Document 1, since a stop button must be pressed to stop calling or the like, for example, the caregiver operates a detection device such as a mat sensor before the caregiver presses the stop button. A problem arises in which it is not possible to prevent a false report when it happens.

  An electronic nurse call device according to the present invention includes a radio reception unit that receives a radio signal transmitted in response to detection of a moving object by a human sensor and generates an operation start signal, and a notification signal in response to the operation start signal. And a care time for controlling whether or not to generate the notification signal by the notification signal generation unit according to an elapsed time of the care time. A control unit, wherein the care time control unit stops generation of the notification signal by the notification signal generation unit until the care time reaches a preset end time, and is set before the end time. If the operation start signal is input during the end notice period, the time measurement process is performed again after resetting the measured value of the care time.

  According to the electronic nurse call device according to the present invention, since the care time can be extended by causing the human sensor to detect a moving object, it is possible to prevent a call or the like from being erroneously transmitted.

Embodiment 1
Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows a block diagram of the nurse call system according to the first embodiment. The nurse call system shown in FIG. 1 includes a main body 1, a human sensor 2, and a caller display device 4. Among these, the electronic nurse call device according to the first embodiment includes the main body 1 and the human sensor 2.

  The human sensor 2 is disposed in the vicinity of the bed, detects the movement of the cared person, and notifies the main body 1 that the cared person has moved by a wireless signal. The human sensor 2 includes a wireless transmission unit 21 that transmits a wireless signal and a sensor unit 22 that detects a moving object. When the sensor unit 22 detects the presence of a moving object within a preset detection area, the sensor unit 22 outputs a moving object detection signal SEN. The wireless transmission unit 21 outputs a wireless signal to the main body unit 1 in response to the input of the moving object detection signal SEN.

  When the main body 1 receives a notification from the human sensor 2 that a moving object has been detected by a wireless signal, the main body 1 generates a nurse call signal in response to the notification. This nurse call signal is transmitted to the caller display device 4 via a wall surface terminal NST provided on the wall surface. The caller display device 4 displays the caller. In the nurse call system, the caller display device functions as a parent device, and the main body 1 functions as a child device. That is, in FIG. 1, only one main body 1 is shown, but when there are a plurality of rooms in the building, one main body 1 is installed in each room. The caller display device receives a nurse call signal via the display device side terminal 3. The display device side terminal 3 incorporates a device such as an exchanger and is output from a plurality of rooms. Coordinate nurse call signals. In addition, from the wall surface terminal NST of each room to the display device side terminal 3 is connected by the local wiring 5.

  The main body unit 1 includes a wireless reception unit 11, a control unit 12, a nurse call indicator 13, and a measurement state indicator (for example, a care time indicator 14). The wireless receiving unit 11 generates an operation start signal ST when it receives that the human sensor 2 has detected a moving object by a wireless signal. The control unit 12 receives the operation start signal ST and generates a nurse call signal. Further, the control unit 12 controls lighting, blinking, and extinguishing of the nurse call indicator 13 and the care time indicator 14 according to the operation state. Furthermore, the control part 12 performs the care time control process which prevents that a nurse call signal is transmitted accidentally after receiving the input of the operation start signal ST. Details of the care time control process will be described later.

  Next, an installation method of the human sensor 2 and a detection area of the human sensor 2 will be described. FIG. 2 is a diagram for explaining the installation position of the human sensor 2 according to the first embodiment and the detection area of the nurse call system according to the first embodiment.

  As shown in the top view of FIG. 2, the human sensor 2 has a detection area that extends in a fan shape starting from the human sensor 2. In the nurse call system according to the first embodiment, the detection area is set so as to cover the upper body of the care recipient. Moreover, it is preferable to arrange | position the main-body part 1 in the position which can be seen from the human sensitive sensor 2. FIG. And the main-body part 1 is connected to the wall surface terminal 3 with a cable.

  Further, as shown in the side view of FIG. 2, in the first embodiment, the detection area is set so as to cover the upper body of the patient. In the detection area, the body of the cared person is outside the detection area when sleeping, and the cared person raises his hand, or a part of the cared person's body is detected when the cared person gets up. It is set to be within the area.

  By setting the detection area in this way, it is possible to prevent the human sensor 2 from detecting a moving object when another person passes through a corridor around the bed (for example, a foot). Further, by setting the detection area in this way, it is possible to notify a nurse call at an early stage when the cared person gets up. In this way, by detecting the rising at an early stage, it is possible to prevent an accident such that the cared person falls from the bed or falls when landing.

  Next, the main body 1 will be described in detail. FIG. 3 shows a block diagram of the electronic nurse call device (particularly the main body 1) according to the first embodiment. As shown in FIG. 3, the main body unit 1 includes a wireless reception unit 11 and a control unit 12. And the control part 12 has the notification signal production | generation part 31, the nurse call switch 32, the care time control part 33, and the LED drive part 34. FIG.

  The report signal generator 31 generates a report signal CAL in response to the operation start signal ST generated in response to the radio receiver 11 receiving a radio signal. The report signal generator 31 generates a report signal CAL having a predetermined enable period in advance regardless of the length of the period in which the operation start signal ST is enabled. Accordingly, the notification signal CAL is prevented from being at a high level throughout the moving object detection time by the human sensor 2.

  The nurse call switch 32 outputs a nurse call signal in response to the notification signal CAL. The nurse call switch 32 is, for example, for short-circuiting between two wires that transmit a nurse call signal in response to the notification signal CAL becoming high level.

  The care time control unit 33 starts measuring the care time according to the report signal CAL, and controls whether the report signal CAL can be generated by the report signal generation unit 31 according to the elapsed time of the care time. More specifically, the care time control unit 33 stops the generation of the notification signal by the notification signal generation unit 31 until the measured care time reaches a preset end time. In addition, when the operation start signal ST is input during the end notice period set before the end time, the care time control unit 33 resets the measured value of the care time and measures the care time again. Process. That is, the care time control unit 33 prohibits a new notification signal CAL from being generated during the care time regardless of the presence or absence of the operation start signal ST generated in response to the moving object detection by the human sensor 2. In addition, the care time control unit 33 can extend the care time when the operation start signal ST is input again just before the end of the care time.

  The care time control unit 33 outputs an indicator control signal (for example, the care time signal LCS1 and the end notice signal LCS2) for controlling the blinking interval of the care time indicator provided outside according to the elapsed time of the care time, and the care time If is the end notice period, the blinking interval of the care time indicator is made shorter than in other periods. More specifically, the care time control unit 33 enables the care time signal LCS1 for a period from when the care time measurement starts until the care time reaches the end time (for example, high level). Further, the care time control unit 33 sets the end notice signal LCS2 to an enable state (for example, high level) when the value of the measured care time is the end notice period.

  After the notification signal CAL is input, the LED drive unit 34 lights the nurse call indicator 13 until the care time signal LCS1 is disabled. Further, the LED drive unit 34 blinks the care time indicator 14 in response to the care time signal LCS1 being enabled. Further, when the end notice signal LCS2 is enabled during the period in which the care time signal LCS1 is enabled, the LED driving unit 34 shortens the blinking interval of the care time indicator 14 as compared with other periods.

  Next, the operation of the electronic nurse call device according to the first embodiment will be described. First, the flowchart which shows operation | movement of the electronic nurse call apparatus concerning Embodiment 1 is shown in FIG. As shown in FIG. 4, in the electronic nurse call device according to the first embodiment, the main body 1 and the human sensor 2 operate in response to the power being turned on, and the human sensor 2 detects a moving object. The moving object detection process is continued until it is detected (step S1).

  When a moving object is detected in step S1, the wireless reception unit 11 of the main body 1 generates an operation start signal ST, and the report signal generation unit 31 generates a report signal CAL in response to the operation start signal ST. (Step S2). Next, the main body 1 transmits a nurse call signal in response to the notification signal CAL, and turns on the nurse call indicator (step S3). Further, the care time control unit 33 of the main body unit 1 outputs the care time signal LCS1 in response to the notification signal CAL to blink the care time indicator (step S3).

  Subsequently, the care time control unit 33 of the main body 1 resets the measurement value of the care time in response to the input of the notification signal CAL (step S4), and starts measuring the care time (step S5). In addition, the care time control unit 33 sets the notification invalidation signal DIS in an enabled state (for example, high level) at the start of measurement of the care time, and prohibits the generation of the new notification signal CAL by the notification signal generation unit 31. (Step S6).

  Subsequently, the care time control unit 33 maintains the current state until the care time time reaches a preset end notice time, and in response to the care time time reaching the end notice time, the end notice signal LCS2 Is enabled (for example, at a high level), and the blinking interval of the care time indicator is made shorter than before (steps S7 and S8).

  Subsequently, the care time control unit 33 waits for detection of a moving object by the human sensor 2 until the value of the care time reaches a preset end time (steps S9 and S10). And the care time control part 33 resets the measured value of care time, when a moving body is detected by the human sensor 2 in the end notice period which performs the process of step S9, S10 (YES branch of step S9). (Step S4), the measurement of the care time is started again (Step S5). On the other hand, if no moving object is detected by the human sensor 2 during the end notice period (YES branch of step S10), the care time control unit 33 sets the notification invalidation signal DIS to a disabled state (for example, low level). The prohibition of the generation of the notification signal CAL is canceled (step S11). Further, the care time control unit 33 sets the care time signal LCS1 and the end notice signal LCS2 to the disabled state (for example, low level), turns off the nurse call indicator 13 and the care time indicator 13 (step S12), and again detects the human sensor. 2 waits until a moving object is detected (step S1).

  Next, an operation according to the flowchart shown in FIG. 4 will be described using a timing chart. FIG. 5 is a timing chart showing the operation of the electronic nurse call device according to the first exemplary embodiment. The timing chart shown in FIG. 5 shows the case where the moving object is not detected during the end notice period and the process ends without extending the initially set care time.

  First, in the example shown in FIG. 5, a moving object is detected at timing T0. Therefore, at timing T0, the moving object detection signal SEN is enabled according to the detection of the moving object by the human sensor 2. Then, the main body unit 1 is notified via a radio signal that the moving object detection signal SEN has been enabled. Therefore, in the main body unit 1, the wireless reception unit 11 enables the operation start signal ST in response to reception of the wireless signal. In response to the operation start signal ST being enabled, the notification signal generator 31 enables the notification signal CAL, and the nurse call signal NCS is enabled in response to the enabled notification signal CAL. The nurse call indicator 13 is turned on in response to the notification signal CAL being enabled.

  Subsequently, in the electronic nurse call device according to the first embodiment, the calling process by the nurse call is finished at the timing T1, and the measurement of the care time is started. At this timing T1, the notification signal generator 31 causes the notification signal CAL to fall. Then, in response to the fall of the notification signal CAL, the care time control unit 33 enables the notification invalidation signal DIS. Thereby, the report signal generator 31 stops generating a new report signal CAL. Thereafter, the care time control unit 33 starts measuring the care time. During the care time measurement period, the care time control unit 33 enables the care time signal LCS1. Thereby, the care time indicator 14 blinks at a slow interval.

  Subsequently, at timing T2, the value of the care time reaches the end notice time. Thereby, in the electronic nurse call device according to the first exemplary embodiment, the care time control unit 33 enables the end notice signal LCS2 to be enabled. Thereby, the care time indicator 14 blinks at an early interval.

  At time T3, the care time value reaches the end time. Therefore, the electronic nurse call device according to the first embodiment cancels the generation prohibition state of the notification signal CAL by disabling the notification invalidation signal DIS at the timing T3. At timing T3, the electronic nurse call according to the first embodiment turns off the nurse call indicator 13 and the care time indicator 14 by disabling the care time signal LCS1 and the end notice signal LCS2. That is, in the electronic nurse call device according to the first embodiment, the period from timing T1 to T3 is the care time period, and the period from timing T2 to T3 is the end notice period.

  FIG. 6 is a timing chart showing the operation of the electronic nurse call device according to the first embodiment. The timing chart shown in FIG. 6 shows a case in which the moving object is detected during the end notice period, and the process ends after the initially set care time is extended. In the example shown in FIG. 6, the processing up to timing T12 when the end notice period starts is the same as the processing up to timing T0 to T2 shown in FIG.

  In the timing chart shown in FIG. 6, the operation start signal ST is enabled based on the moving object detection signal SEN during the end notice period set in the period from the timing T12 to T14. Therefore, in the timing chart shown in FIG. 6, the end notice signal LCS2 is switched from the enable state to the disable state at the timing T13 when the operation start signal ST is switched to the enabled state, and the blinking interval of the care time indicator 14 is delayed. Further, at the timing T13, the care time control unit 33 resets the measurement value of the care time and newly starts the measurement of the care time from the timing T13. In addition, according to the re-measurement of the care time, the care time end processing at the end time that was initially set is discarded.

  Subsequently, at timing T15, the value of the care time reaches the end notice time again. Thereby, in the electronic nurse call device according to the first exemplary embodiment, the care time control unit 33 enables the end notice signal LCS2 in an enabled state. Thereby, the care time indicator 14 blinks at an early interval.

  At timing T16, the care time value reaches the end time. Therefore, the electronic nurse call device according to the first embodiment cancels the generation prohibition state of the notification signal CAL by disabling the notification invalidation signal DIS at the timing T16. At timing T3, the electronic nurse call according to the first embodiment turns off the nurse call indicator 13 and the care time indicator 14 by disabling the care time signal LCS1 and the end notice signal LCS2. As shown in the timing chart shown in FIG. 6, in the electronic nurse call device according to the first embodiment, when the operation start signal ST is input during the care time end notice period, the care time is extended.

  From the above description, the electronic nurse call device according to the first embodiment extends the care time when the operation start signal ST is input during the end notice period set immediately before the end of the initially set care time. Can do. Thereby, the electronic nurse call device according to the first embodiment can prevent the nurse call signal from being erroneously transmitted even when care is not completed within the initially set care time.

  In the electronic nurse call device according to the first embodiment, the motion start signal ST is generated by detecting a moving object in the detection area of the human sensor 2 set above the upper half of the non-caregiver. For example, since a part of the body inevitably enters the detection area during the nursing work, the electronic nurse call device according to the first embodiment is used so that a button operation or the like is performed particularly during the nursing work. The care time is extended. In other words, the electronic nurse call device according to the first embodiment can perform care time only by putting a part of the body in the detection area located near the non-caregiver without operating the button where the caregiver is away. It is possible to prevent erroneous transmission of the nurse call signal while performing care without worrying about the time limit.

  Even when there is no part of the body in the detection area during the care work, the care time is extended by putting a part of the body in the detection area in response to the blinking interval of the care time indicator 14 being shortened. can do. Even in this case, it is possible to prevent erroneous transmission of the nurse call signal without operating the button at a position where the caregiver is away.

  Further, the electronic nurse call device according to the first embodiment can prohibit the generation of a nurse call signal due to the fact that a moving object is automatically detected immediately after the nurse call signal is transmitted. Thereby, the electronic nurse call device according to the first embodiment can prevent erroneous transmission of the nurse call signal without performing any button operation even when the caregiver rushes in response to the nurse call. Thus, by automatically preventing erroneous transmission of the nurse call signal, the work burden on the user can be greatly reduced.

  Further, in the electronic nurse call device according to the first embodiment, the prohibition state of the generation of the nurse call signal based on the operation start signal ST is assisted in response to the measurement value of the care time reaching the end value. That is, the user of the electronic nurse call device according to the first embodiment can restore the non-caregiver watching process by the human sensor 2 without performing any operation. Thereby, by using the electronic nurse call device according to the first embodiment, it is possible to prevent the device from operating due to an operation error of a switch or the like.

Therefore, in the description of the timing chart shown in FIG. 8, the operation of the human sensor portion will be particularly described.

  In the example shown in FIG. 8, the human sensor 2a detects a moving body at the timing T20. At timing T20, the sensor unit 22a of the human sensor 2a enables the moving object detection signal SEN. Then, the light control unit 23a of the human sensor 2a turns on the auxiliary light 24a. Then, the light control unit 23a maintains the auxiliary light in a lit state for a predetermined period (for example, the same period as the period until the care time reaches the end time). On the other hand, the human sensors 2b to 2d that have not detected the moving body maintain the auxiliary lights 24b to 24d in the off state.

  From the above description, in the electronic nurse call device according to the second embodiment, a plurality of human sensors are provided for one main body 1. In this case, it is difficult to determine which human sensor has called the nurse call. However, in the electronic nurse call device according to the second embodiment, the human sensors 2a to 2d illuminate the ceiling with the auxiliary light according to the moving object detection signal SEN. Thereby, the caregiver who rushed to can recognize the non-caregiver who needs assistance with the light of the auxiliary light as a clue without hesitation.

  Further, in the electronic nurse call according to the second embodiment, since the auxiliary light illuminates the ceiling, the caregiver does not hesitate to call the bed from the ceiling light, even in a room where a plurality of beds are partitioned by a curtain or the like. Can be recognized.
