Description

  The present invention relates to a nurse call system that allows a patient not only to call a medical worker such as a nurse but also to call a medical worker according to the patient's condition.

  The nurse call system installed in facilities such as hospitals and welfare facilities consists of a nurse call master unit installed in the nurse center and a corridor lamp installed on the corridor near the entrance of the hospital room and connected to the nurse call master unit. Each patient's bed is provided with a wall-embedded handset that is installed on a wall surface in a hospital room and connected to a corridor lamp.

  The wall-mounted type handset has a call button, a speaker, and a microphone for calling medical personnel, so that it can communicate with the nurse call base unit side, but it can be connected to the outlet provided on the surface. By connecting the plug of the nurse call slave unit, it is possible to communicate with the nurse call master unit side also by the nurse call slave unit attached to the wall-embedded slave unit. Here, the nurse call slave is detachable from the wall-embedded slave. When the nurse call slave unit is attached to the wall-embedded slave unit, the call button may not be provided on the wall-embedded slave unit.

  Examples of nurse call slaves include a hand-push button and a hand-type slave. Here, the grip push button is provided with a call button, and is only for calling and has no call function. Therefore, a call between the patient and a medical worker is performed by a speaker or a microphone provided in the wall-embedded slave unit. In addition to the call button, the hand-type handset has a built-in speaker and microphone and has a call function.

  In addition, when the patient presses the call button provided on the wall-mounted handset, the call button provided on the grip push button, or the call button provided on the hand-type handset, the nurse call handset and the corridor lamp call. Is notified. On the other hand, in a wall-embedded handset, a grip push button, and a hand-type handset, the patient is notified that a call is being made reliably by lighting / flashing of a call confirmation lamp. In this state, when a medical worker presses the recovery button provided on the nurse call master unit, hallway lamp, or wall-mounted slave unit, the nurse call master unit and hallway lamp stop calling notification, The implantable child device, the grip push button, and the hand child device stop the lighting / flashing of the call confirmation lamp.

  By the way, in the nurse call system, there is known a device for notifying a drop call when an abnormality such as drop or disconnection occurs in the nurse call slave (for example, Patent Document 1). In the nurse call system described in Patent Document 1, the nurse call slave unit is provided with a power supply circuit that receives external power and supplies power to each circuit in the main body, and further, between the power supply circuit and each circuit in the main body. The power supply disconnecting circuit is provided, and when the power supply is stopped, the power supply disconnecting call is made.

  By the way, depending on the condition of the patient, not only the nurse call cordless handset that calls by operating the call button, but also a mat sensor that detects that the patient has fallen from the bed or falls, or detects that an abnormality has occurred in the patient. In some cases, a sensor or medical device is required. Therefore, in addition to the outlet for connecting the nurse call slave unit plug provided in the wall-embedded slave unit, an outlet for connecting the plug of the above-described device (hereinafter referred to as patient condition detection device) is provided. It is necessary to provide it. Here, also regarding the patient state detection device, when an abnormality such as dropout or disconnection occurs, it is necessary to notify the dropout call.

  Moreover, in the technique described in Patent Document 1, a drop call is always notified unless an abnormality such as a drop or disconnection of the nurse call slave is resolved. This is to prevent the nurse call slave unit from being used without the abnormality being resolved. In such a state, even if the health care worker presses the recovery button provided on the nurse call master unit, hallway light, wall-embedded slave unit, as long as the abnormality of the nurse call slave unit has not been resolved, The drop call notification will not stop. In addition, regarding the patient state detection device, the drop-out call is always notified as long as the device abnormality is not resolved.

  In order to eliminate such a situation, the drop call can be recovered only by pressing the recovery button provided on the wall-embedded slave that is making the drop call. It is conceivable that the operation of the recovery button is made effective even when the abnormality of the patient state detection device has not been eliminated. This is because it is necessary for the medical staff to always go to the hospital room at the site in order to identify the cause of the dropped call.

  On the other hand, the patient state detection device is a device that calls a medical worker according to the patient's state, unlike a nurse call cordless handset that calls a medical worker at the patient's will. Therefore, when the patient condition detection device calls, if the call confirmation lamp provided on the wall-embedded handset is turned on / flashes, the patient thinks that the call has been made, and the patient is shrunken or called. There was a problem that some cases of unnatural behavior occurred so as not to be performed. Here, the unnatural action refers to an action in which the patient avoids the mat sensor when the mat sensor is used as the patient state detection device.

  In order to eliminate such a situation, it is conceivable that the call confirmation lamp of the wall-mounted type slave unit is not lit / flashed for calls from the patient state detection device (including dropped calls). Thereby, since the patient is not notified of the call from the patient state detection device, there is no case where the patient atrophy or unnatural action is caused due to this.

Japanese Patent Laid-Open No. 2004-112015

  However, as described above, when the dropped call can be recovered only by the recovery button provided on the wall-embedded slave unit, and the call confirmation lamp is not lit / flashed when calling from the patient state detection device, The following problems occur. In other words, even if an abnormality such as dropout or disconnection occurs in the patient condition detection device, the call confirmation light of the wall-mounted slave unit does not light up / blink. It becomes difficult to specify the state detection device.

  The present invention has been made in order to solve such a problem, and has been dropped into a nurse call cordless handset that makes a call by a patient's operation or a patient condition detection device that makes a call by detecting a patient's condition. While notifying the patient state detection device that the call has been made from the patient state detection device while properly making the notification that is made when an abnormal state such as breakage or disconnection occurs properly It is an object of the present invention to make it possible for a health care worker to easily perform a recovery operation when an abnormal state occurs.

  In order to solve the above-described problems, in the present invention, a call from a nurse call slave unit detachably attached to a wall-embedded slave unit, occurrence of an abnormal condition of the nurse call slave unit, and a wall-embedded type The call from the patient condition detection device detachably attached to the slave unit and the occurrence of an abnormal state of the patient condition detection device are distinguished and determined, and in either case, the nurse call master unit performs notification. Yes. In addition, when it is determined that a call from the patient state detection device or an abnormal state has occurred, the call confirmation lamp of the wall-mounted type slave unit is not lit / flashed. On the other hand, if it is determined that an abnormal condition has occurred in the patient condition detection device, only the recovery operation unit provided in the wall-mounted type slave unit to which the patient condition detection device is connected is valid. A message that prompts the operation for restoration at the installation location and at the site is output to the nurse call master unit or a portable terminal carried by a medical worker.

  According to the present invention configured as described above, the calling confirmation lamp of the wall-mounted slave unit does not light / blink for the calling from the patient state detection device or the occurrence of an abnormal state. It is possible to prevent the patient from realizing that a call or an abnormal condition has occurred. In addition, for the occurrence of an abnormal condition from a patient condition detection device, only the recovery operation part of the wall-mounted type slave unit to which the device is connected is valid, so that the cause of the occurrence of the abnormal condition is specified. In addition, a medical worker who visits the site can easily perform a recovery operation. Further, since the drop call can be stopped even in the state where the abnormal state such as dropout or disconnection is not solved, the abnormal state is appropriately notified. In addition, a message prompting the operation of the patient condition detection device where the abnormal condition has occurred and on-site recovery is output to the nurse call parent device or the mobile terminal carried by the medical staff. Therefore, the recovery operation can be easily performed without relying on the caller to turn on / flash the call confirmation lamp.

In the present embodiment, the mat sensor 10 is illustrated as an apparatus for detecting a specific state of a patient, but the present invention is not limited to this.

  The call operation unit 2 is used when a patient calls a medical worker, and includes a call button and the like. Moreover, the subunit | mobile_unit interface 3 is connected to the wall-embedded subunit | mobile_unit interface 22, and connects the nurse call subunit | mobile_unit 1 and the wall-embedded subunit | mobile_unit 20 electrically. The detection unit 11 detects that the patient has stepped off the bed and stepped on the mat sensor 10. Here, since the detection method of the mat sensor 10 is well-known, detailed description is abbreviate | omitted. The interface 12 is connected to the wall-embedded child device interface 22 and electrically connects the mat sensor 10 and the wall-embedded child device 20.

  The wall-embedded child device control unit 21 controls each component of the wall-embedded child device 20 as described later, and generates various signals as described later. The wall-embedded slave unit interface 22 connects the slave unit interface 3 and the interface 12. The wall-embedded child device interface 22 is for connecting the wall-embedded child device 20 and the nurse call parent device 40 for communication.

  Here, when the patient wants to call a medical worker, the call operation unit 2 is operated. Then, the wall-embedded child device control unit 21 generates a child device call signal. Here, the slave unit call signal includes identification information for distinguishing the wall-embedded slave unit 20 from other wall-embedded slave units 20. Further, information such as a bed number is used as the identification information. On the other hand, it is assumed that the detection unit 11 detects that the patient has stepped on the mat sensor 10. Then, the wall-embedded slave unit control unit 21 generates a patient state detection device calling signal. Here, the patient state detection device calling signal includes identification information for distinguishing this wall-mounted implantable device 20 from other wall-embedded devices 20.

In addition, when the wall-embedded child device controller 21 generates a child device call signal, the wall-embedded child device controller 21 is called from the nurse call child device 1 to the nurse call parent device 40. A call confirmation sound for causing the patient to grasp this is output from the speaker 23. The call confirmation lamp 24 is configured by an LED or the like. When the wall-embedded child device control unit 21 generates a child device call signal, the wall-embedded child device control unit 21 includes the nurse call child device 1. In order to make the patient know that the call has been made to the nurse call parent device 40, the call confirmation lamp is lit / flashed. The microphone 25 collects sound around the bed (mainly patient's voice) and outputs it as an audio signal to the wall-embedded handset interface 22. At this time, the wall-embedded child device interface 22 transmits the audio signal input from the microphone 25 to the nurse call parent device 40. In the case where the implantable cordless handset controller 21 generates a patient state detection device calling signal, the implantable cordless cordless handset controller 21 does not output a call confirmation sound from the speaker 23, and the call confirmation lamp Do not light / flash 24.

  The restoration operation unit 26 outputs the child device call signal and the patient condition detector device call signal generated by the wall-embedded child device control unit 21 to the corridor lamp 30 and the nurse call parent device 40, and the corridor lamp 30 and the nurse call. As will be described later, the master unit 40 is operated in a state in which a call is being notified, and the nurse call slave unit 1, the wall-embedded slave unit 20, the corridor lamp 30, and the nurse call master unit 40 are notified of a call. It is for returning to the state before being called. In addition, when the recovery operation unit 26 is operated, the wall-embedded child device control unit 21 stops lighting / flashing of the call confirmation sound and the call confirmation light output from the speaker 23.

  The drop-off determining unit 27 is configured such that the plug P1 of the nurse call slave unit 1 is dropped from the outlet C1 of the wall-mounted slave unit 20, the cord of the nurse call slave unit 1 is disconnected, or the plug P2 of the mat sensor 10 is connected to the wall. It is detected that the plug-in device 20 is disconnected from the outlet C2 or the mat sensor 10 is disconnected. Further, when the disconnection determination unit 27 detects the disconnection of the plugs P1 and P2 or the disconnection of the cord, the disconnection determination unit 27 determines whether it is the nurse call slave unit 1 or the mat sensor 10. Here, since a well-known technique is used for the method of detecting dropout or disconnection, detailed description thereof is omitted.

  When the drop-off determining unit 27 determines that the plug P1 of the nurse call slave unit 1 has dropped from the outlet C1 of the wall-embedded slave unit 20 or the cord has been disconnected, the wall-embedded slave unit control unit 21 Generates a slave unit abnormality signal indicating that an abnormal state has occurred in the nurse call slave unit 1. Here, the slave unit abnormality signal includes identification information for distinguishing the wall-embedded slave unit 20 from other wall-embedded slave units 20. Further, information such as a bed number is used as the identification information. On the other hand, when the drop determining unit 27 determines that the plug P2 of the mat sensor 10 has dropped from the outlet C2 of the wall embedded type child device 20 or the cord has been disconnected, the wall embedded type child device control unit 21 Generates a patient condition detection device abnormality signal indicating that an abnormal condition has occurred in the mat sensor 10. Here, the patient state detection device abnormality signal includes identification information for distinguishing the wall-embedded slave unit 20 from other wall-embedded slave units 20. Further, information such as a bed number is used as the identification information. Further, the wall-embedded slave unit interface 22 outputs a slave unit abnormality signal and a patient condition detection device abnormality signal generated by the wall-embedded subunit control unit 21 to the nurse call parent unit 40.

  In addition, when the wall-embedded child device control unit 21 generates a child device abnormality signal or a patient condition detection device abnormality signal, the wall-embedded child device control unit 21 causes the speaker 23 to output a call confirmation sound. The call confirmation lamp 24 is not lit / flashed. In addition, the restoration operation unit 26 outputs the child device abnormality signal and the patient condition detector device abnormality signal generated by the wall-embedded child device control unit 21 to the corridor lamp 30 and the nurse call parent device 40, and As will be described later, the nurse call master unit 40 is operated in a state in which the occurrence of an abnormal state is being notified, and the nurse call slave unit 1, the wall-embedded slave unit 20, the corridor lamp 30, and the nurse call master unit 40 are The state before the notification of the occurrence of abnormality is restored.

  Next, each component of the corridor lamp 30 will be described. Note that the corridor lamp 30 is not an essential component of the present invention. A name display column N1 for displaying the name of a patient who is hospitalized in a hospital room in which the corridor lamp 30 is installed is arranged in the center of the front of the housing of the corridor lamp 30. A room number is written above the name display column N1. In addition, above the room number, a handset calling signal, a patient state detecting device calling signal, a handset abnormality signal, and a patient state detecting device output from the wall-embedded handset interface 22 of the wall-embedded handset 20 are displayed. An indicator lamp L1 that is lit / flashed when an abnormal signal is input is provided. Here, by changing the lighting / flashing pattern of the indicator lamp L1 according to each signal, a medical worker who has seen the corridor lamp 30 can distinguish and grasp the type of call and the type of occurrence of an abnormal state.

  The corridor lamp restoration operation unit 31 outputs the slave unit call signal and the patient condition detection device call signal generated by the wall-embedded slave unit control unit 21 to the corridor lamp 30 and the nurse call master unit 40, It is operated in a state in which the nurse call master unit 40 is informing the call, and before the call notification is performed on the nurse call slave unit 1, the wall-embedded slave unit 20, the corridor lamp 30, and the nurse call master unit 40. It is for returning to the state of. Note that the slave unit abnormality signal and the patient condition detection device abnormality signal generated by the wall-embedded slave unit control unit 21 are output to the corridor lamp 30 and the nurse call master unit 40, and the corridor lamp 30 and the nurse call master unit 40 are abnormal. In the state in which the occurrence of the state is being notified, the operation of the corridor lamp restoration operation unit 31 is invalid.

  Next, each component of the nurse call parent device 40 will be described. The nurse call parent device 40 includes a parent device control unit 41, a parent device interface 42, a storage unit 43, a notification unit 44, a parent device recovery operation unit 45, and a display unit 46. In addition, on the front surface of the casing of the nurse call parent device 40, a name display column N2 for displaying the names of patients managed by the nurse call parent device 40 is arranged on the right side. The name display column N2 is arranged together for each patient who is hospitalized in the same hospital room. And the bed number is described to the left of each name display column N2, and the individual indicator lamp L2 is installed below the bed number. In addition, a handset H used when a medical worker makes a call with a patient is installed on the left side of the front surface of the casing of the nurse call parent device 40, and a speaker SP is installed on the back surface thereof. Is installed. Further, a display unit 46 described later is installed above the handset H.

  The base unit control unit 41 is for controlling each component of the nurse call base unit 40 as described later, and is configured by a CPU (Central Processing Unit) or the like. The master unit interface 42 is used for communication by connecting the nurse call master unit 40 and the wall-embedded slave unit 20 via the corridor lamp 30. Here, the master unit interface 42 inputs the slave unit call signal, the patient condition detection device call signal, the slave unit abnormality signal, and the patient condition detection device abnormality signal output from the wall-embedded slave unit 20. Further, when a call can be made between the wall-embedded slave unit 20 and the nurse call master unit 40, the master unit interface 42 transmits an audio signal to the wall-embedded slave unit 20 to be embedded in the wall. An audio signal is received from the slave unit 20.

  The storage unit 43 is configured by a storage device such as a memory or a hard disk drive, and identifies identification information (for example, a bed number) of the implantable child device 20 connected to the nurse call parent device 40 and a patient. Patient identification information (for example, patient name, etc.) to be associated is stored. The storage unit 43 stores image information of a screen displayed on the display unit 46.

  The notification unit 44 is for notifying the calling from the nurse call slave device 1 or the mat sensor 10 or the occurrence of an abnormal state. Moreover, the alerting | reporting part 44 is comprised by the indicator lamp L2 installed in the vicinity of the speaker SP which outputs an audio | voice, and the name display column N2. Here, when the master unit interface 42 inputs the slave unit call signal, the patient condition detection device call signal, the slave unit abnormality signal, and the patient condition detection device abnormality signal output from the wall-embedded slave unit 20, the master unit control unit 41 operates the notification unit 44. Here, the master unit control unit 41 stores in the storage unit 43 identification information that matches the identification information included in the slave unit call signal, patient state detection device call signal, slave unit abnormality signal, and patient state detection device abnormality signal. If it is determined that there is matching identification information in the storage unit 43, the patient identification information stored in association with it is acquired. Then, the indicator lamp L2 corresponding to the patient identification information is turned on / flashed. The sound pattern output from the speaker SP and the blinking pattern of the indicator lamp L2 are made different depending on each signal, so that the medical worker who sees the nurse call parent device 40 determines the type of call and the type of occurrence of an abnormal state. It can be grasped separately.

  The master unit recovery operation unit 45 outputs the slave unit call signal and the patient condition detection device call signal generated by the wall-embedded slave unit control unit 21 to the corridor lamp 30 and the nurse call master unit 40, and displays the corridor lamp 30. The operation is performed in a state where the notification unit 44 of the lamp L1 or the nurse call parent device 40 is informing the call. When the master unit recovery operation unit 45 is operated, the master unit control unit 41 notifies the nurse call slave unit 1, the wall-embedded slave unit 20, the corridor lamp 30, and the nurse call master unit 40 of calling. Return to the previous state. That is, the lighting / flashing of the indicator lamp L1 is stopped in the corridor lamp 30, and in the wall-mounted type slave unit 20, the wall-embedded type cordless handset controller 21 outputs the call confirmation sound and the call confirmation output from the speaker 23. The lighting / flashing of the lamp 24 is stopped. Moreover, the main | base station control part 41 stops operation | movement of the alerting | reporting part 44. FIG.

  Here, in order to perform recovery operations among the wall-embedded slave unit 20, the corridor lamp 30, and the nurse call master unit 40, a recovery signal is sent from the device that has performed the recovery operation to the other devices. Is sending. Further, the master recovery operation unit 45 operates in conjunction with the off-hook of the handset H. That is, when the medical staff is off-hooking the handset H in a state in which the call is being notified by the notification unit 44, the master recovery operation unit 45 is operated.

  Note that the slave unit abnormality signal and the patient condition detection device abnormality signal generated by the wall-embedded slave unit control unit 21 are output to the corridor lamp 30 and the nurse call master unit 40, and the corridor lamp 30 and the nurse call master unit 40 are abnormal. In the state in which the occurrence of the state is being notified, the operation of the master recovery operation unit 45 is invalid.

  The display unit 46 is configured by a display device such as a liquid crystal display, and displays a message to be described later. When the parent device interface 42 inputs the patient state detection device abnormality signal output from the wall-embedded child device 20, the parent device control unit 41 operates the notification unit 44. At the same time, the parent device control unit 41 performs identification information included in the child device calling signal, the patient state detection device calling signal, the child device abnormality signal, and the patient state detection device abnormality signal. Then, the base unit control unit 41 generates a bed number that is identification information and a message that prompts the mat sensor 10 installed in the vicinity of the hospital bed to perform recovery at the site and displays the message on the display unit 46. Let

  For example, when the mat sensor 10 attached to the wall-mounted type child device 20 installed near the bed of the patient name “Taro Yamada” is dropped, the call confirmation lamp 24 of the wall-mounted type child device 20 is Does not light / blink. On the other hand, the indicator lamp L1 of the hallway lamp 30 is lit / flashed. In addition, the notification unit 44 of the nurse call parent device 40 also operates. In this state, the display unit 46 displays a message such as “Please remove the mat sensor at 101-1 and restore the site”. In addition, even if the medical worker off-hooks the handset H in this state, the operation of the notification unit 44 or the like does not stop (the recovery operation is not performed. Further, the medical worker performs the corridor lamp recovery operation unit 31 of the corridor lamp 30). Does not stop the operation of the notification unit 44. However, a medical worker who sees the above message goes to the hospital room where "Taro Yamada" is located and is installed near the hospital bed. When the recovery operation unit 26 is operated, the operation of the notification unit 44 and the like is stopped even when the mat sensor 10 is detached.

  The medical staff may operate the recovery operation unit 26 after connecting the plug P2 of the mat sensor 10 that has been dropped to the outlet C2 of the wall-mounted type slave unit 20, or after operating the recovery operation unit 26 The plug P2 of the mat sensor 10 that has been dropped may be connected to the outlet C2 of the wall-embedded slave unit 20. In addition to such a usage method, the medical staff can also use the mat sensor 10 intentionally. For example, the medical worker removes the plug P <b> 2 of the mat sensor 10 from the outlet C <b> 2 of the wall-embedded portable device 20 and operates the recovery operation unit 26 immediately thereafter. By such a series of operations, even if the mat sensor 10 is intentionally removed, the occurrence of abnormality is not notified from each device.

  Next, the operation of the nurse call system according to the present embodiment will be described. FIG. 3 is a flowchart showing the operation of the nurse call system according to the present embodiment. In addition, in this description, description of the corridor lamp 30 is omitted. First, whether or not the nurse call slave unit 1 has dropped is checked by the wall-embedded slave unit control unit 21 and the master unit control unit 41 (step S1). If the wall-embedded slave unit control unit 21 and the base unit control unit 41 determine that the nurse call slave unit 1 has dropped (YES in step S1), the base unit control unit 41 operates the notification unit 44. Then, the wall-embedded child device control unit 21 blinks (or lights) the call confirmation lamp 24 (step S2).

  The wall-embedded child device control unit 21 and the parent device control unit 41 check whether or not the abnormal state (the drop of the nurse call child device 1) has been resolved (step S3). When the wall-embedded child device control unit 21 and the parent device control unit 41 determine that the abnormal state has not been resolved (NO in step S3), the processing in step S3 is repeated. On the other hand, if the wall-embedded slave control unit 21 and the master control unit 41 determine that the abnormal state has been resolved (YES in step S3), the master control unit 41 operates the notification unit 44. Then, the wall-embedded cordless handset controller 21 turns off the call confirmation lamp 24 (step S4).

  If it is determined in step S1 that the nurse call cordless handset 1 has not been removed by the wall-embedded cordless cordless handset control unit 21 and the base unit control unit 41 (NO in step S1), the mat sensor 10 It is checked by the wall-embedded child device control unit 21 and the parent device control unit 41 whether or not it has dropped out (step S5). When it is determined by the wall-embedded slave control unit 21 and the master control unit 41 that the mat sensor 10 is not dropped (NO in step S5), the process returns to step S1.

  On the other hand, when the wall-embedded slave control unit 21 and the base unit control unit 41 determine that the mat sensor 10 has dropped (YES in step S5), the base unit control unit 41 operates the notification unit 44. The bed number and a message prompting the restoration at the site are displayed on the display unit 46, and the wall-embedded slave unit control unit 21 operates the restoration operation unit 26 without blinking (or lighting) the call confirmation lamp 24. Is validated (step S6).

  Then, the wall-embedded slave control unit 21 checks whether or not the recovery operation unit 26 has been operated (step S7). If the wall-embedded child device control unit 21 determines that the recovery operation unit 26 has not been operated (NO in step S7), the processing in step S7 is repeated. On the other hand, if the wall-embedded slave unit control unit 21 determines that the recovery operation unit 26 has been operated (YES in step S7), the base unit control unit 41 stops the operation of the notification unit 44, and the message Is deleted from the display unit 46 (step S8).

  As described above in detail, according to the present embodiment, a call from the nurse call slave unit 1 detachably attached to the wall-embedded slave unit 20 and occurrence of an abnormal state (dropout) of the nurse call slave unit 1 Etc.), a call from the mat sensor 10 which is a patient state detection device detachably attached to the wall-embedded child device, and occurrence of an abnormal state of the mat sensor 10 (dropout, etc.). The base unit control unit 21, the dropout determination unit 27, and the base unit control unit 41 make a distinction, and in any case, the base unit control unit 41 operates the notification unit 44. In addition, when it is determined that a call from the mat sensor 10 or an abnormal state has occurred, the wall-embedded slave unit control unit 21 does not light / blink the call confirmation lamp 24 of the wall-embedded slave unit 20. I have to. On the other hand, when it is determined that an abnormal state has occurred in the mat sensor 10, the wall-embedded slave unit control unit 21 restores the operation unit of the wall-embedded slave unit 20 to which the mat sensor 10 is connected. Only the operation 26 is made effective, and the master control unit 41 displays a message for prompting an operation for restoration at the installation location and the site of the mat sensor 10 on the display unit 26.

  As a result, when the calling from the mat sensor 10 which is a patient state detection device or an abnormal state occurs, the calling confirmation lamp 24 of the wall-mounted type slave unit 20 does not light / blink. It is possible to prevent the patient from realizing the occurrence of In addition, regarding the occurrence of an abnormal state of the mat sensor 10 (dropout, etc.), only the operation of the recovery operation unit 26 of the wall-embedded slave unit 20 to which the mat sensor 10 is connected is valid, so A medical worker who visits the site to identify the cause of the occurrence can easily perform the recovery operation. Moreover, since the corridor lamp 30 can stop the operation of notification in the nurse call master unit 40 even in a state where an abnormal state such as dropout or disconnection has not been resolved, the notification of the occurrence of the abnormal state is appropriately performed. It becomes like this. In addition, a message prompting the operation of the mat sensor where the abnormal condition has occurred and on-site recovery is displayed on the display unit 46 of the nurse call parent unit 40. The recovery operation can be easily performed without relying on the lighting / flashing of the lamp 24.

  In this embodiment, when the patient condition detecting device such as the nurse call slave 1 and the mat sensor 10 is attached to the wall-embedded slave 20, the plugs P1, P2 are connected to the separate outlets C1, C2. However, it is not limited to this. For example, the distribution device may be attached to one outlet, and the plugs P1 and P2 of each device may be connected to the outlets C1 and C2 provided in the distribution device.

  In the present embodiment, the installation location of the patient state detection device such as the mat sensor 10 and a message prompting the recovery at the site are displayed on the display unit 46 of the nurse call parent device 40, but the present invention is not limited to this. . For example, a message may be displayed on a display screen of a mobile terminal carried by a medical worker.

  In the present embodiment, the installation location of the patient state detection device such as the mat sensor 10 and a message prompting the recovery at the site are displayed on the display unit 46 of the nurse call parent device 40, but the present invention is not limited to this. . For example, a message may be output by voice from the speaker SP, or a message may be output by voice from a speaker of a portable terminal carried by a medical worker.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
