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 configured with a nurse call master unit. 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.

Further, there is also known a system in which a patient information terminal is connected to a nurse call slave unit so that a call can be made using the patient information terminal (see, for example, Patent Document 1). In the nurse call system described in Patent Document 1, the patient information terminal connected to the patient slave unit is provided with a display unit consisting of a liquid crystal touch panel display, and corresponds to the purpose of calling the nurse call master unit when using the nurse call. A call menu including options is displayed on the display unit, and a call for each purpose is executed by touching one of the options. The nurse call master unit displays an information screen such as the type of call, the corresponding number of doctors, nurses, associate nurses, etc., patient information, etc., in response to the call from the patient for each purpose.

JP-A-2002-132929

According to the nurse call system described in Patent Document 1, the type of call (the purpose for which the patient made the call) can be determined by looking at the information screen of the nurse call master unit displayed when the call for each purpose is executed. It is possible to grasp. However, since it is not always possible for the nurse to go to the hospital room immediately after performing the response operation on the nurse call master unit, the purpose of the call confirmed on the information screen may be forgotten. In this case, it is necessary for the nurse to confirm the purpose of the call with the patient in the hospital room, and there is a problem that the efficiency of the nursing work is reduced.

As one method for solving such a problem, in the call menu displayed on the display unit of the patient information terminal described in Patent Document 1, the option touched for calling can be distinguished from others. It is conceivable to leave it displayed in the state. In this way, the nurse who visits the patient can grasp what kind of business the patient made the call by looking at the display state of the call menu.

By the way, it is conceivable that the call menu options are written in a foreign language in response to the case where the patient is a foreigner. However, when the call menu options are written in a foreign language in this way, even if the touched options are displayed identifiablely, for a nurse who is not fluent in a foreign language, see the display of the options. There was a problem that it was difficult to grasp the patient's requirements.

The present invention has been made to solve such a problem, and even if the patient is a foreigner at the site where the call is made, the nurse can use the patient without the explanation of the patient. The purpose is to make it easy to confirm the matter.

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 requirements written in a foreign language other than the original language used in the notification operation of the nurse call master unit. It has a message button and sends a call signal in response to the pressing of any of the message buttons, while the display state is such that the content of the message corresponding to the pressed message button is displayed in an identifiable manner. , The display state is canceled according to the predetermined restoration operation performed in the room where the nurse call slave unit is installed. Further, in the present invention, the message corresponding to the message button identifiable according to the pressing of the message button according to the predetermined operation performed in the room where the nurse call slave unit is installed. The related processing for outputting the synthetic voice of the original language representing the content is executed.

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, even if a ringing signal is transmitted to the nurse call master unit to perform a predetermined notification operation and the notification operation is stopped in response to a predetermined response operation, a predetermined recovery is performed in the room where the nurse call slave unit is installed. The above display state is maintained until the operation is performed, and the display state is canceled when the recovery operation is performed. In addition, when a predetermined operation is performed in the room where the nurse call slave unit is installed, the original language is a synthetic voice that expresses the content of the message corresponding to the message button that was displayed so that it was pressed. It is output. For this reason, at the site where the call is made by pressing the message button, the nurse cannot grasp the content of the message by looking at the message button in which the content of the message is written in a foreign language. However, the patient's requirements can be grasped by the synthetic voice output in the original language. As a result, the nurse can easily confirm the patient's requirements at the site where the call is made, even if the patient is a foreigner, without requiring explanation of the patient.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 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, and a hand slave unit 6 (claims). (Corresponding to the second nurse call slave unit in the scope of the above) and the requirement transmission type slave unit 7 (corresponding to the nurse call slave unit and the nurse call device in the claims). 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. This notification operation (displaying information on the display) is performed in the original language of the country in which the nurse call system is used. In this embodiment, it is assumed that the nurse call system is used in Japan and the original language is Japanese.

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 Japanese 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 installed on the patient's bedside. 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 more 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. On the message button 7a, the content of the message is written in a foreign language other than the original language used in the notification operation of the nurse call master unit 1. In addition, the message transmission type slave unit 7 is provided with a recovery button 7d, and the nurse can press the recovery button 7d to put it in the recovery state. 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 and generates a synthetic voice in Japanese corresponding to the button identification information included in the call signal received from the message transmission type slave unit 7 in response to the pressing of the message button 7a. The voice signal of the synthesized voice is transmitted to the nurse call master unit 1 via the wall-embedded slave unit 4, the corridor light 3, and the controller 2. Further, the repeater 5 corresponds to the button identification information included in the recovery signal (an example of the synthetic voice output instruction signal in the claims) received from the message transmission type slave unit 7 in response to the pressing of the recovery button 7d. A Japanese synthetic voice is generated, and the voice signal of the generated synthetic voice is transmitted to the hand-held handset 6. Details of these operations will be described later. In addition, although there is a case of "transmitting a synthetic voice" in this specification, this is synonymous with "transmitting a voice signal of a synthetic voice".

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 a foreign language other than Japanese. This is based on the assumption that a foreigner other than the Japanese is a patient and the foreigner uses the message transmission type handset 7. In the example of FIG. 2, "toilet", "agonizing", "medicine", "tube feeding", "painful", "phlegm" , "Infusion" and "affair" are written in English on each of the eight message buttons 7a.

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, by pressing the lighting switch 7b when the wording of the message written on the message button 7a cannot be seen, all the message buttons 7a are illuminated and the wording is displayed. 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.

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.

Further, when the nurse presses the recovery button 7d, the button identification information that can identify the message button 7a (the message button 7a that is lit according to the pressing by the patient) in which the content of the message is identifiable is displayed. A recovery signal (synthetic voice output instruction signal) including the above is transmitted to the repeater 5. Then, a Japanese synthetic voice representing the content of the message corresponding to the message button 7a is generated by the repeater 5, the voice signal of the synthetic voice is transmitted to the hand-held handset 6, and is output from the speaker 6b. To.

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, the hand-held slave unit 6, 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 has functional configurations such as 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, a synthetic voice transmission unit 505, and a recovery signal reception unit 506 ( It is equipped with an instruction signal receiver within the scope of claims). Further, the repeater 5 includes a voice data storage unit 511 as a storage medium.

The hand-held handset 6 according to the present embodiment includes a synthetic voice receiving unit 601 and a synthetic voice output unit 602 as functional configurations. The message transmission type slave unit 7 according to the present embodiment has, as functional configurations, a press detection unit 701, a call signal transmission unit 702, a display control unit 703, a response notification reception unit 704, and a recovery signal transmission unit 705 (claims). It is equipped with an audio output-related processing execution unit).

Each functional block included in the nurse call master unit 1, repeater 5, hand-held slave unit 6, and message transmission slave unit 7 shall be configured by any of hardware, DSP (Digital Signal Processor), and software. Is possible. 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 press detection unit 701 detects that the lighting switch 7b is pressed by the patient, the press detection unit 701 notifies the display control unit 703 to that effect. Further, when the push detection unit 701 detects that the recovery button 7d is pressed by the nurse, the press detection unit 701 notifies the display control unit 703 and the recovery signal transmission unit 705 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. The display control unit 703 controls 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 reception unit 704.

The recovery signal transmission unit 705 displays the message button 7a identifiable by the display control unit 703 in response to the pressing of the recovery button 7d (corresponding to a predetermined operation in the claims and a predetermined recovery operation). A recovery signal (synthetic voice output instruction signal) including identifiable button identification information is transmitted to the repeater 5. This process corresponds to "a related process for outputting a synthetic voice in the original language representing the content of the message corresponding to the message button identifiable by the display control unit" in the claims.

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 the hand-held handset 6 can transmit 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 a 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). The call signal of one specific call type (for example, general call) among a plurality of call types is relayed to the nurse call master unit 1.

That is, the message buttons 7a of "toilet" and "infusion" shown in FIG. 2 are generally assigned a call type called special call, and are "agonizing", Message buttons 7a such as "painful" are generally assigned to a call type called emergency call, but even when these message buttons 7a are pressed, a call signal is displayed. The relay unit 501 transmits a call signal for a general call to the nurse call master unit 1.

As described above, when the call signal relay unit 501 receives the call signal from the hand-held handset 6, the nurse call master unit uses the call signal as a call type call signal corresponding to the pressed call button 6a. 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.

The recovery signal receiving unit 506 receives a recovery signal (synthetic voice output instruction signal) transmitted by the recovery signal transmitting unit 705 of the message transmission type slave unit 7 in response to pressing the recovery button 7d of the message transmission type slave unit 7. Receive. When the recovery signal receiving unit 506 receives the recovery signal transmitted by the recovery signal transmitting unit 705, the recovery signal receiving unit 506 notifies the synthetic voice generation unit 504 of the button identification information included in the recovery signal.

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.

The synthetic voice generation unit 504 reads the voice data corresponding to the button identification information included in the call signal or the recovery signal received from the message transmission type slave unit 7 from the voice data storage unit 511 and generates the synthetic voice of the original language. That is, in the synthetic voice generation unit 504, when the call signal relay unit 501 receives the call signal from the message transmission type slave unit 7, the synthetic voice generation unit 504 receives the notification of the button identification information from the call signal relay unit 501.

I am trying to output.

According to the present embodiment configured in this way, when the nurse who visits the patient after receiving the call presses the recovery button 7d, it is lit up to that point and the content of the message can be identified (however, in a foreign language). A synthetic voice representing the content of the message corresponding to the message button 7a displayed in (according to) is output in the original language. Therefore, at the site where the call is made by pressing the message button 7a, the nurse can grasp the content of the message by looking at the message button 7a in which the content of the message is written in a foreign language. Even without the patient's explanation, the patient's requirements can be easily grasped by the synthetic voice output in the original language.

In the above embodiment, as an example of a predetermined recovery operation performed in the room where the nurse call slave unit (message transmission type slave unit 7) is installed, a recovery button provided on the message transmission type slave unit 7 is provided. Although the pressing operation of 7d has been illustrated, the present invention is not limited to this.

In such a configuration, it is preferable that the synthetic voice output instruction signal is transmitted to the repeater 5 in response to the pressing of the dedicated button. When the wording written on the message button 7a is the original language (Japanese), the nurse can understand the content of the message only by looking at the wording on the message button 7a, so that the output of the synthetic voice is unnecessary. Therefore, by providing a dedicated button different from the recovery button 7d, one message transmission type slave unit 7 can be used in various language notations according to the patient, and the wording of the message button 7a. Is written in the original language, the display state of the message button 7a is only released in response to the pressing of the recovery button 7d, and the synthetic voice can be prevented from being output.

Further, in the above embodiment, when the recovery signal receiving unit 506 receives the recovery signal from the message transmission type slave unit 7, the synthetic voice generated by the repeater 5 is output from the speaker 6b of the hand type slave unit 6. However, the present invention is not limited to this. For example, the repeater 5 may be provided with a speaker, and the synthetic voice may be output from the speaker of the repeater 5. However, there is an advantage that the configuration of the repeater 5 can be simplified by outputting the synthesized voice by using the speaker 6b originally provided in the hand-held handset 6.

Further, in the above embodiment, when the recovery button 7d is pressed, an example in which the repeater 5 generates a synthetic voice and outputs it from the speaker 6b of the hand-held handset 6 has been described. Not limited. For example, the message transmission type slave unit 7 may be provided with a synthetic voice generation function and a speaker, and the synthetic voice may be output from the speaker of the message transmission type slave unit 7. In this case, the processing related to the generation and output of the synthetic voice performed inside the message transmission type slave unit 7 corresponds to the "message button identifiable by the display control unit" in the claims. Corresponds to "related processing for outputting synthetic speech in the original language that expresses the content of the case".

Further, in the above embodiment, the example of wirelessly connecting the message transmission type slave unit 7 and the repeater 5 is shown, but the connection may be made by wire. Further, in the above embodiment, an example in which the message transmission type slave unit 7 operates by obtaining power from the built-in battery has been described, but the message transmission type slave unit 7 is connected to an outlet of a general power supply to be a message transmission type. The slave unit 7 may be operated by obtaining power from an outlet.

Further, in the above embodiment, the configuration in which the message button 7a as hardware is provided in the housing of the message transmission type slave unit 7 has been described, but the present invention is not limited to this. For example, the message button 7a may be configured by the GUI (graphical user interface) of the software displayed on the display with the touch panel.

When the message button 7a is configured by the GUI in this way, the display control unit 703 highlights or highlights the GUI of the pressed message button 7a, or highlights or highlights the GUI of the pressed message button 7a, or displays the unpressed message button 7a. By displaying the GUI in gray out, it is possible to display the content of the message corresponding to the pressed message button 7a in an identifiable manner.

Further, in the above embodiment, the configuration in which the repeater 5 is connected between the wall-embedded handset 4, the hand-held handset 6, and the message transmission type handset 7 has been described, but the present invention is limited thereto. Not done. For example, by providing the functional configuration of the repeater 5 in the message transmission type slave unit 7, the repeater 5 is omitted, and the hand type slave unit 6 and the message transmission type slave unit are compared with the wall-embedded type slave unit 4. 7 may be connected.

Further, in the above embodiment, the language of the wording written on the message button 7a of the message transmission type slave unit 7 is a foreign language, and the language of the synthetic voice output from the speaker 6b of the hand type slave unit 6 is Japanese. However, it is not limited to this. For example, even when the nurse call system is used in Japan, if the patient is Japanese and the nurse is a foreigner, it is marked on the message button 7a of the message transmission type slave unit 7. The wording may be Japanese, and the synthetic voice output from the speaker 6b of the handheld handset 6 may be the foreign language used by the above-mentioned foreigner. As described above, the language of the synthetic voice output from the speaker 6b of the hand-held handset 6 is preferably the original language of the nurse, and the wording written on the message button 7a of the message-transmitting handset 7 is described above. It is preferable that the language is different from the original language and the language used by the patient.
