Description

The present invention relates to a nurse call system and a nurse call device, and more particularly to a field recovery type nurse call system and a nurse call device used therein.

Generally, a nurse call system installed in a hospital or a long-term care facility is installed in a nurse call slave unit installed at the bedside of a patient or a care recipient (hereinafter, simply referred to as "patient") and a nurse station. It is equipped with a nurse call master unit and a corridor light installed near the entrance of each room such as a hospital room or a nursing room. In addition, as a nurse call master unit, a nurse call system equipped with a portable nurse call master unit carried by doctors, nurses, and caregivers (hereinafter, simply referred to as "nurses") is also provided.

In the nurse call system configured in this way, when the patient operates the call button of the nurse call slave unit, a predetermined notification operation is performed on the nurse call master unit, whereby the nurse can be called. When the nurse performs a response operation such as off-hook on the nurse call master unit in response to this, the notification operation by the nurse call master unit stops, and a communication path is formed between the nurse call slave unit and the nurse call master unit. Then, the patient and the nurse can talk with each other.

The corridor light is linked to the nurse call master unit, and when the patient operates the call button of the nurse call slave unit, the LED etc. provided in the corridor light lights up and calls in the hospital room where the corridor light is installed. Is informed that is being performed. This allows a nurse walking in the corridor to identify the room in which the calling patient is located. In addition, when the nurse performs a response operation on the nurse call master unit, the LED of the corridor light turns off. In this way, the recovery method is such that when the nurse responds to the nurse call master unit, the corridor light is automatically turned off and the response to the call is completed (so-called recovery state). It is called the "normal recovery method".

However, in such a nurse call system, the nurse can be restored by simply performing a response operation on the nurse call master unit, so the nurse who is busy with other calls and other tasks is in the hospital room where the patient is. There may be cases where you forget to go. In order to solve such a problem, when a response operation is performed on the nurse call master unit, the notification operation is stopped, but the LED of the corridor light is left on, and the nurse is in the hospital room where the patient is. A nurse call system is provided in which the LED of the corridor light is turned off when a predetermined restoration operation is performed (see, for example, Patent Document 1). Such a recovery method is called a "site recovery method".

Japanese Unexamined Patent Publication No. 2016-2199

If the nurse call system adopts the on-site restoration method, it will not be restored unless the nurse goes to the hospital room where the patient is and performs the prescribed operation, so it is possible to give a strong alert to the nurse, and the nurse can do it. The problem of forgetting to go to the hospital room where the patient is located can be suppressed.

However, since it is not always possible for the nurse to go to the hospital room immediately after performing the response operation, the patient's requirements confirmed by the telephone during the response operation may be forgotten. In this case, it is necessary for the nurse to reconfirm the contents of the requirements with the patient in the hospital room, and there is a problem that the efficiency of the nursing work is reduced. In addition, since the patient is required to give the same explanation as during the call, there is also a problem that the patient is uncomfortable and mentally stressed.

Further, in the case of the on-site restoration method, it is possible for a nurse walking in the corridor to see the lighting state of the corridor light, grasp that the response to the call has not been completed, and provide necessary nursing care as appropriate. However, the nurse who does not answer the call and talk to the patient does not know the patient's requirements by nature, so it is necessary to confirm the patient's requirements in the hospital room. Therefore, the patient has to repeat the same explanation as during the call, which causes discomfort and psychological stress to the patient.

The present invention has been made to solve such a problem, and in a nurse call system adopting a site recovery method, a nurse can perform a patient at the site where the call is made without requiring explanation of the patient. The purpose is to make it easy to confirm the requirements of.

In order to solve the above-mentioned problems, in the nurse call system of the present invention, the nurse call slave unit has a plurality of message buttons, and a call signal is transmitted in response to pressing any of the message buttons, while pressing the button. The content of the message corresponding to the displayed message button is displayed in an identifiable display state, and the display state is canceled according to a predetermined recovery operation.

According to the present invention configured as described above, when the message button is pressed in the nurse call slave unit, the content of the message corresponding to the pressed message button is displayed in an identifiable display state. .. After that, a ringing signal is transmitted to the nurse call master unit to perform a predetermined notification operation, and even if the notification operation is stopped in response to the predetermined response operation, until the predetermined recovery operation is performed on the nurse call slave unit. The above display state is maintained, and the display state is canceled when the recovery operation is performed. Therefore, the nurse can confirm the patient's message by checking the display state of the nurse call slave unit at the site where the call is made by pressing the message button. This allows the nurse to easily confirm the patient's requirements without having to ask the patient again, and avoids discomfort and mental stress to the patient. be able to.

FIG. 1 is a diagram showing an overall configuration example of a nurse call system according to the present embodiment. Although the nurse call system installed in the hospital will be described here as an example, the nurse call system of the present embodiment is not limited to the one installed in the hospital. For example, it can be applied when it is installed in a nursing facility or the like.

As shown in FIG. 1, the nurse call system of the present embodiment includes a nurse call master unit 1, a controller 2, a corridor light 3, a wall-embedded slave unit 4, a repeater 5, a hand slave unit 6, and a requirement. It is configured to include a transmission type slave unit 7 (corresponding to a nurse call slave unit and a nurse call device within the scope of the patent claim). The nurse call master unit 1 may be installed at a nurse station, or may be a portable nurse call master unit carried by an individual nurse. The wall-embedded handset 4, the repeater 5, the hand handset 6, and the message transmission handset 7 are installed in the patient's room.

The nurse call master unit 1 is for operating a response to a call from a patient (hand-type slave unit 6 or message transmission type slave unit 7) and for a nurse to make a call with the patient. When the nurse call master unit 1 receives a call from a patient, the nurse call master unit 1 performs a predetermined notification operation. The notification operation is performed by outputting a ringing tone from the speaker included in the nurse call master unit 1 and displaying information such as the patient and call type related to the call on the display provided in the nurse call master unit 1.

If the nurse performs a response operation such as off-hook during the execution of this notification operation, the nurse call master unit 1 stops the above-mentioned notification operation and forms a communication path. Although the details will be described later, when a response operation is performed in response to the call from the hand-held handset 6, the nurse call master unit 1 forms a communication path with the hand-held handset 6 and makes a call with the patient. Be ready to do it. Further, when a response operation is performed in response to the call from the message transmission type slave unit 7, the nurse call master unit 1 forms a communication path with the repeater 5 and is sent from the repeater 5. Receives synthetic voice and outputs it from the speaker.

The controller 2 is arranged between the nurse call master unit 1 and the corridor light 3, and controls calls and data transmission / reception. The data to be transmitted and received includes a call signal sent from the hand-held handset 6 or the message transmission type slave unit 7 to the nurse call master unit 1, and a response notification sent from the nurse call master unit 1 to the message transmission type slave unit 7. The signal, the voice signal of the synthetic voice sent from the repeater 5 to the nurse call master unit 1, and the like are included.

The corridor light 3 is installed outside the vicinity of the entrance of each hospital room. The corridor light 3 is provided with a display device, and when the patient name in the hospital room is displayed and the patient in the hospital room calls a nurse using the hand-held handset 6 or the message transmission type handset 7. , It is displayed that the call has been made. It should be noted that the indication that the call has been made may be made by lighting or blinking the LED. The LED turns off when a predetermined recovery operation is performed.

The corridor light 3 transmits a call signal transmitted from the hand-held handset 6 or the message transmission type handset 7 via the repeater 5 to the nurse call master unit 1 via the controller 2. Further, the corridor light 3 transmits a response notification signal transmitted from the nurse call master unit 1 via the controller 2 to the message transmission type slave unit 7 via the wall-embedded slave unit 4 and the repeater 5. To do. Further, the corridor light 3 is a voice signal transmitted from the repeater 5 via the communication path formed by the response operation of the nurse call master unit 1 (call voice of the patient input from the microphone of the handset slave unit 6). , Or the synthetic voice for message transmission generated by the repeater 5) is transmitted to the nurse call master unit 1 via the controller 2 and from the nurse call master unit 1 via the controller 2. The voice signal related to the call voice of the nurse sent is transmitted to the hand-held handset 6 via the wall-embedded handset 4 and the repeater 5.

The wall-embedded handset 4 is embedded and installed in each bedside wall of the hospital room. The wall-embedded handset 4 is connected to a corridor light 3. The wall-embedded handset 4 includes a connection terminal for connecting the repeater 5 or the hand-held handset 6. It is also possible to directly connect the hand-mounted handset 6 to the wall-embedded handset 4, but in the present embodiment, the repeater 5 is connected to the wall-embedded handset 4 and the hand is connected to the repeater 5. The transponder machine 6 is connected. The wall-embedded handset 4 transmits and receives the above-mentioned call signal, response notification signal, and voice signal between the corridor light 3 and the repeater 5. The wall-embedded handset 4 may be provided with a call button for the patient to call the nurse, and a microphone and a speaker used by the patient to have a conversation with the nurse.

The hand-held handset 6 is connected to the wall-embedded handset 4 or the repeater 5 and is installed on the bedside of the patient. As described above, the hand-held handset 6 can be directly connected to the wall-embedded handset 4, but in the present embodiment, the repeater 5 connected to the wall-embedded handset 4 can be connected. The hand-held handset 6 is connected. The hand-held handset 6 includes a call button 6a for the patient to call the nurse, a microphone (not shown) and a speaker 6b used by the patient to have a conversation with the nurse.

The hand-held handset 6 includes a call button 6a corresponding to one or a plurality of call types, and when a patient operates any of the call buttons 6a, a call signal of the call type corresponding to the operated call button 6a is provided. Is transmitted to the nurse call master unit 1 via the repeater 5, the wall-embedded slave unit 4, the corridor light 3, and the controller 2. The call type is, for example, a general call, an emergency call, a specific call (toilet or drip), and the like.

The message transmission type slave unit 7 is wirelessly connected to the repeater 5 and installed on the bedside of the patient. For example, the message transmission type slave unit 7 is connected to the repeater 5 using the wireless communication means of Bluetooth (registered trademark). The message transmission type slave unit 7 and the repeater 5 perform one-to-one wireless communication. In wireless communication, the repeater 5 registers pairing with the message transmission type slave unit 7. The repeater 5 has a function of performing processing related to pairing registration. For example, after the pairing standby state is set by pressing and holding the setting switch 5a provided in the repeater 5, the message transmission type slave unit 7 is performed by performing a predetermined operation on the pairing message transmission type slave unit 7. Pairing registration is performed by wirelessly transmitting the identification information to the repeater 5 and storing the identification information in the repeater 5.

The message transmission type slave unit 7 includes a plurality of message buttons 7a for the patient to call a nurse, and when the patient operates any of the message buttons 7a, the operated message button 7a is identified. A ringing signal including possible button identification information is transmitted to the repeater 5. The message transmission type slave unit 7 has a built-in battery and operates by obtaining power from the battery. In the present embodiment, the repeater 5 is provided with a pairing registration function and a voice synthesis function described later, so that the battery consumption of the message transmission type slave unit 7 is suppressed.

The repeater 5 is installed between the message transmission type slave unit 7 and the nurse call master unit 1 (specifically, between the message transmission type slave unit 7 and the wall-embedded slave unit 4). .. The repeater 5 is connected to a general power outlet and operates by obtaining power from the outlet. The repeater 5 transmits and receives the above-mentioned call signal, response notification signal, and voice signal between the wall-embedded handset 4, the hand handset 6, and the message transmission handset 7. Regarding the voice signal, the repeater 5 generates a synthetic voice corresponding to the button identification information included in the call signal received from the message transmission type handset 7, and the voice signal of the generated synthetic voice is embedded in the wall. It is transmitted to the nurse call master unit 1 via the machine 4, the corridor light 3, and the controller 2. The details of this operation will be described later.

FIG. 2 is a diagram showing an example of an external configuration of the message transmission type slave unit 7. As shown in FIG. 2, the message transmission type slave unit 7 includes a plurality of message buttons 7a. In the present embodiment, eight message buttons 7a are arranged side by side on both sides of the front surface of the housing. On each of the message buttons 7a, words that simply express the content of the message that the patient conveys to the nurse are written. In the example of FIG. 2, the words "toilet", "painful", "medicine", "tube feeding", "painful", "take sputum", "intravenous drip", and "business" are used for eight words. It is described in the case button 7a respectively.

These requirements buttons 7a are made of a translucent resin material, a glass material, or the like, and an LED is installed on the back side (inside of the housing) thereof. The message button 7a can be operated by pressing the message button 7a, and when the patient presses any of the message buttons 7a, the LED corresponding to the pressed message button 7a lights up and is pressed. A ringing signal including button identification information that can identify the message button 7a is transmitted to the repeater 5.

As described above, since the message button 7a is made of a translucent material, when the LED on the back side lights up, the pressed message button 7a appears to shine, and which message button 7a is pressed. Can be seen at a glance. That is, by lighting the LED corresponding to the pressed message button 7a, the content of the message corresponding to the pressed message button 7a (the content of the wording written on the message button 7a) can be identified. It will be in the state displayed in. In the following description, turning on or off the LED arranged on the back side of the message button 7a is referred to as "turning on or off the message button 7a" for convenience.

The message transmission type slave unit 7 includes a lighting switch 7b. The lighting switch 7b can also be operated by pressing the lighting switch 7b, and when the patient presses the lighting switch 7b, all the message buttons 7a are lit. For example, after the lights in the hospital room are turned off at night, when the wording of the message written on the message button 7a cannot be seen, the lighting switch 7b is pressed to make all the message buttons 7a illuminate and the wording. It is possible to check the contents of. The display control unit (described later) included in the message transmission type slave unit 7 has an adjustment function for lighting the LED with two levels of brightness, and when the lighting switch 7b is pressed, it is used for all purposes. Turn on the button 7a with low brightness. Further, when any of the message buttons 7a is pressed, the display control unit lights the pressed message button 7a with high brightness.

The message transmission type slave unit 7 includes a response indicator lamp 7c. The response display lamp 7c is a lamp for notifying that the nurse has answered the call made by pressing the message button 7a. The response indicator lamp 7c also has a configuration in which LEDs are arranged on the back side of a translucent material. When the nurse performs a response operation on the nurse call master unit 1, a response notification signal is transmitted from the nurse call master unit 1 to the message transmission type slave unit 7. Then, when the message transmission type slave unit 7 receives this response notification signal, the response display lamp 7c lights up. This allows the patient to confirm whether the nurse has responded to the call made by pressing any of the message buttons 7a.

In the present embodiment, when the patient notices an error in pressing the message button 7a before the nurse responds (before the response indicator lamp 7c lights up), the patient presses the correct message button 7a again. It is possible to switch to the call corresponding to the message button 7a. In this case, the display control unit turns off the message button 7a that was pressed first, and turns on the message button 7a that was pressed again later. As a result, if the message button 7a is pressed again before the nurse responds, only one message button 7a is lit.

In addition, when an additional message occurs after the nurse responds (after the response indicator lamp 7c lights up), the patient responds to the other message button 7a by pressing the other message button 7a. It is possible to make additional calls to make. In this case, the display control unit additionally lights the message button 7a pressed later while maintaining the lighting state of the message button 7a pressed first. As a result, when the other message buttons 7a are pressed after the nurse responds, the number of lit message buttons 7a becomes plural.

The display of the response display lamp 7c can be as follows. For example, when another message button 7a is additionally pressed after the nurse responds (after the response indicator lamp 7c lights up), the response indicator lamp 7c is turned off once, and then the message transmission type child is used. When the machine 7 receives the response notification signal, the response indicator lamp 7c may be turned on again. Alternatively, after the response display lamp 7c is turned on for a predetermined time from the time when the message transmission type slave unit 7 receives the response notification signal, the response display lamp 7c is turned on regardless of whether or not another message button 7a is pressed. It may be turned off automatically.

The message transmission type slave unit 7 includes a recovery button 7d for the nurse to operate. The recovery button 7d is arranged on an upper surface different from the front surface of the housing in which the patient-operated message button 7a and the lighting switch 7b are arranged in order to prevent the patient from accidentally operating the recovery button 7d. There is. The recovery button 7d is a button for turning off the message button 7a pressed by the patient to put it in the recovery state. That is, by pressing the recovery button 7d when the nurse arrives at the hospital room (corresponding to a predetermined recovery operation performed in the room where the nurse call slave unit is installed), the message button pressed by the patient. It is possible to release the lit state of 7a and return the message transmission type slave unit 7 to the restored state.

FIG. 3 is a block diagram showing a functional configuration example of the nurse call system according to the present embodiment. Here, a functional configuration example of the nurse call master unit 1, the repeater 5, and the message transmission type slave unit 7 is shown.

As shown in FIG. 3, the nurse call master unit 1 according to the present embodiment has a call signal receiving unit 101, a notification processing unit 102, a response operation detecting unit 103, a call path forming unit 104, and a synthetic voice receiving unit 105 as functional configurations. And a synthetic voice output unit 106 is provided. Further, the nurse call master unit 1 includes a speaker 111 and a display 112 as a hardware configuration.

The repeater 5 according to the present embodiment includes a call signal relay unit 501, a response notification relay unit 502, a call path-related processing unit 503, a synthetic voice generation unit 504, and a synthetic voice transmission unit 505 as functional configurations. Further, the repeater 5 includes a voice data storage unit 511 as a storage medium. The message transmission type slave unit 7 according to the present embodiment includes a press detection unit 701, a call signal transmission unit 702, a display control unit 703, and a response notification reception unit 704 as functional configurations.

Each functional block included in the nurse call master unit 1, the repeater 5, and the message transmission type slave unit 7 can be configured by any of hardware, DSP (Digital Signal Processor), and software, respectively. For example, when configured by software, each of the above functional blocks is actually configured to include a computer CPU, RAM, ROM, and the like, and is realized by operating a program stored in the RAM and ROM. The program may be stored in another storage medium such as a hard disk or a semiconductor memory.

The press detection unit 701 of the message transmission type slave unit 7 detects the press of the message button 7a and the lighting switch 7b by the patient. Further, the push detection unit 701 detects the push of the recovery button 7d by the nurse. When the press detection unit 701 detects that the message button 7a is pressed by the patient, the press detection unit 701 notifies the call signal transmission unit 702 and the display control unit 703 to that effect. When the push detection unit 701 detects that the lighting switch 7b is pressed by the patient or the recovery button 7d is pressed by the nurse, the press detection unit 701 notifies the display control unit 703 to that effect.

In response to the pressing of the message button 7a, the call signal transmission unit 702 transmits a call signal including button identification information that can identify the pressed message button 7a to the repeater 5. The button identification information corresponding to each message button 7a is stored in advance in a storage medium (not shown) of the message transmission type slave unit 7.

The display control unit 703 controls the display of the message button 7a and the response display lamp 7c. That is, when the press of the lighting switch 7b is detected by the press detection unit 701, the display control unit 703 lights all the message buttons 7a with low brightness. For example, the display control unit 703 turns on all the message buttons 7a with low brightness for a certain period of time from the time when the lighting switch 7b is pressed, and then turns off all the message buttons 7a. Alternatively, the display control unit 703 turns on all the message buttons 7a in response to the pressing of the lighting switch 7b, and then turns off all the message buttons 7a when the lighting switch 7b is pressed again. Alternatively, when any of the message buttons 7a is pressed, the message buttons 7a other than the pressed message button 7a may be turned off.

Further, when any of the message buttons 7a is pressed by the press detection unit 701, the display control unit 703 lights the pressed message button 7a with high brightness, so that the pressed message is pressed. The content of the message corresponding to the button 7a (the content of the wording written on the message button 7a) is displayed in an identifiable display state. Further, the display control unit 703 turns off the lit message button 7a (releases the above display state) when the push button 7d is detected by the push detection unit 701. Further, the display control unit 703 turns on the response display lamp 7c when the response notification reception unit 704 receives the response notification signal sent from the nurse call master unit 1.

As described above, the response notification receiving unit 704 receives the response notification signal sent from the nurse call master unit 1 via the repeater 5, and notifies the display control unit 703 to that effect. The response notification signal received by the response notification receiving unit 704 is a signal generated when the nurse calls the nurse by pressing the message button 7a and then the nurse performs a response operation on the nurse call master unit 1. is there. In addition to controlling the lighting of the response display lamp 7c as described above in response to the reception of the response notification signal by the response notification receiving unit 704, the display control unit 703 also lights the message button 7a as follows. To control.

That is, when the display control unit 703 presses the other message button 7a before the response notification receiving unit 704 receives the response notification signal corresponding to the pressing of the one message button 7a, the above-mentioned one Turn off the message button 7a (corresponding to canceling the display state in which the content of the message is displayed identifiable), and turn on the other message buttons 7a (display the content of the message in an identifiable manner). Equivalent to the display state). At this time, the call signal transmission unit 702 retransmits the call signal in response to pressing another message button 7a (hereinafter, this state is referred to as a retransmit state when it is pressed again).

Further, the display control unit 703 receives another message button after the response notification receiving unit 704 receives the response notification signal corresponding to the pressing of one message button 7a and before the recovery button 7d is pressed. When 7a is pressed, the other message buttons 7a are turned on while maintaining the lighting state of one message button 7a. At this time as well, the call signal transmission unit 702 retransmits the call signal in response to the pressing of the other message button 7a (hereinafter, this state is referred to as the retransmission state when the additional button is pressed).

The call signal relay unit 501 of the repeater 5 receives the call signal transmitted from the hand-type handset 6 in response to the pressing of the call button 6a of the hand-type handset 6, and the call corresponding to the pressed call button 6a. It is relayed to the nurse call master unit 1 as a type of call signal. As described above, the call types of the call signal that can be transmitted by the handset handset 6 include general call, emergency call, and specific call (toilet or drip).

Further, when the call signal relay unit 501 receives the call signal transmitted by the call signal transmission unit 702 of the message transmission type slave unit 7, the call signal relay unit 501 notifies the synthetic voice generation unit 504 of the button identification information included in the call signal. At the same time, the call signal is relayed to the nurse call master unit 1 as a call signal of a specific call type (not including button identification information). When the call signal relay unit 501 receives the call signal from the message transmission type slave unit 7, it depends on the content of the button identification information included in the call signal (that is, which message button 7a is pressed). It is relayed to the nurse call master unit 1 as a call signal of a specific call type (for example, general call) among a plurality of call types.

That is, the message buttons 7a for "toilet" and "drip" shown in FIG. 2 are generally assigned a call type called special call, and the message buttons 7a for "painful", "painful", etc. Is generally assigned a call type called emergency call, but even when these message buttons 7a are pressed, the call signal relay unit 501 calls the general call call signal as a nurse call. Send to master unit 1.

As described above, when the call signal relay unit 501 receives the call signal from the hand-held handset 6, the call signal is used as a call type call signal according to the pressed call button 6a, which is a nurse call master unit. Relay to 1. On the other hand, when the call signal relay unit 501 receives the call signal from the message transmission type slave unit 7, the call signal relay unit 501 relays the call signal to the nurse call master unit as a call signal of a specific call type. As described above, in the present embodiment, one of the call types prepared in the nurse call system is used to transmit a call signal for transmitting the patient's message to the nurse by synthetic voice to the nurse call master unit 1. I am trying to be able to do it.

Regarding the call signal received by the call signal relay unit 501 in the retransmit state at the time of re-pressing, only the button identification information included in the call signal is notified to the synthetic voice generation unit 504, and the nurse is used as a call signal of one call type. It may not be relayed to the call master unit 1. In the retransmit state when re-pressed, the nurse has not yet responded, so the notification operation is continuing in the nurse call master unit 1, and even if the call signal is retransmitted, the call type and patient information are both. This is because the content of the notification operation to be performed does not change because it does not change. Whether or not the call signal received by the call signal relay unit 501 is retransmitted in the retransmitted state at the time of re-pressing is determined before the response notification relay unit 502 receives the response notification signal from the nurse call master unit 1. It is possible to determine whether or not the call signal relay unit 501 has re-received the call signal from the message transmission type slave unit 7.

The response notification relay unit 502 receives the response notification signal sent from the nurse call master unit 1 and relays it to the message transmission type slave unit 7. The call path-related processing unit 503 performs processing related to the formation of a call path with the nurse call master unit 1. The process related to the formation of the call path is a process for forming a call path in cooperation with the call path forming unit 104 of the nurse call master unit 1, and is, for example, in response to a request from the call path forming unit 104. Execute processing according to the request.

When a response operation is performed by the nurse call master unit 1 in response to a call from the handset slave unit 6, the call path-related processing unit 503 cooperates with the call path forming unit 104 of the nurse call master unit 1. , Performs the processing necessary to form a communication path between the nurse call master unit 1 and the handset slave unit 6. For the processing in this case, the handset handset 6 also has a call path related processing unit, but the illustration is omitted. Further, when the nurse call master unit 1 performs a response operation to the call from the message transmission type slave unit 7, the call path-related processing unit 503 and the call path forming unit 104 of the nurse call master unit 1 In cooperation with each other, the processing necessary for forming a communication path between the nurse call master unit 1 and the repeater 5 is performed. When a call path is formed between the nurse call master unit 1 and the repeater 5, the call path-related processing unit 503 notifies the synthetic voice generation unit 504 to that effect.
