Description

TECHNICAL FIELD The present invention relates to a nurse call system and a nurse call device, and more particularly to a nurse call system using an on-site recovery method and a nurse call device used therein.

Generally, nurse call systems installed in hospitals, nursing care facilities, etc. consist of a nurse call handset installed at the bedside of a patient or care recipient (hereinafter simply referred to as a "patient"), and a nurse call machine installed at a nurse station. It is comprised of a nurse call main unit and a hallway light installed near the entrance of each room such as a hospital room or nursing room. Furthermore, a nurse call system is also provided that includes a portable nurse call base unit carried by a doctor, nurse, or caregiver (hereinafter simply referred to as a "nurse").

In the nurse call system configured as described above, when a patient operates the call button on the nurse call slave device, a predetermined notification operation is performed on the nurse call base device, thereby allowing the nurse to be called. When the nurse performs a response operation such as off-hook on the nurse call base unit in response to this, the notification operation by the nurse call base unit stops and a communication path is established between the nurse call base unit and the nurse call base unit. The patient and the nurse can now talk on the phone.

The hallway light is linked to the nurse call base unit, and when a patient presses the call button on the nurse call base unit, the LED installed in the hallway light lights up and a call is made in the hospital room where the hallway light is installed. You will be notified that this is taking place. This allows a nurse walking down the hallway to identify the hospital room where the patient who made the call is located. Furthermore, when the nurse performs a response operation on the nurse call base unit, the LED of the hallway light turns off. In this way, the recovery method is such that when a nurse performs a response operation on the nurse call main unit, the hallway lights are automatically turned off and the response to the call is completed (so-called recovery state). This is called the "normal recovery method."

However, in this type of nurse call system, the nurse can recover by simply responding on the nurse call base unit, so nurses who are busy with other calls or other tasks can be in a patient's room. Sometimes I forget to go. In order to solve this problem, when a response operation is performed on the nurse call main unit, the notification operation stops, but the LED of the hallway light remains on, so that the nurse can call the room where the patient is. A nurse call system has been provided that turns off the LED of a hallway light when a user goes to a hospital and performs a predetermined recovery operation (for example, see Patent Document 1). This type of recovery method is called an "on-site recovery method."

Unexamined Japanese Patent Publication No. 2016-2199

A nurse call system that uses the on-site recovery method will not be able to recover unless the nurse goes to the patient's room and performs the prescribed operations. The problem of forgetting to go to a patient's room can be suppressed.

However, since it is not always possible for a nurse to go to the patient's room immediately after performing a response operation, the nurse may forget the patient's business that was confirmed by telephone during the response operation. In this case, it is necessary for the nurse to confirm the details of the patient's business again in the patient's room, resulting in a problem that the efficiency of nursing work is reduced. Furthermore, since the patient is required to provide the same explanation as when making a phone call, there is also the problem of causing discomfort and mental stress to the patient.

In addition, in the case of the on-site recovery method, a nurse walking down the hallway can see the lighting status of the hallway lights, understand that the response to the call has not been completed, and provide necessary nursing care as appropriate. However, a nurse who is not responding to a call or talking to a patient does not know the patient's business, so it is necessary to check the patient's business in the hospital room. Therefore, the patient has to repeat the same explanation as during the call, which causes discomfort and mental stress to the patient.

The present invention was made to solve such problems, and in a nurse call system that adopts an on-site recovery method, a nurse can call a patient at the site where the call is made without requiring an explanation from the patient. The purpose is to make it easy to check the terms and conditions.

In order to solve the above-mentioned problems, in the nurse call system of the present invention, the nurse call handset has a plurality of job buttons, and when any job button is pressed, a call signal is transmitted. The display state is such that the content of the job corresponding to the job button is displayed in an identifiable manner, and a predetermined response operation is performed in response to a predetermined notification operation performed on the nurse call base unit in response to reception of a paging signal. Even if a response notification signal is received informing that the message has been performed, the display state in which the content of the message is displayed in an identifiable manner is maintained until the prescribed recovery operation is performed, and I am trying to cancel the display state.

According to the present invention configured as described above, when the job button is pressed on the nurse call handset, the display state is such that the content of the job corresponding to the pressed job button is displayed in an identifiable manner. . After that, even if a paging signal is sent to the nurse call base unit and a predetermined notification operation is performed, and the notification operation is stopped in response to a predetermined response operation, the call signal will be sent to the nurse call base unit until the specified recovery operation is performed on the nurse call base unit. The above display state is maintained, and the display state is canceled when a recovery operation is performed. Therefore, at the site where the call is made by pressing the job button, the nurse can check the patient's job by checking the display state of the nurse call handset. This allows the nurse to easily confirm the patient's needs without having to ask the patient again, and avoids causing discomfort or mental stress to the patient. be able to.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a diagram showing an example of the overall configuration of a nurse call system according to this embodiment. Note that although a nurse call system installed in a hospital will be explained here as an example, the nurse call system of this embodiment is not limited to one installed in a hospital. For example, it is also applicable when installed in a nursing care facility or the like.

As shown in FIG. 1, the nurse call system of this embodiment includes a nurse call base unit 1, a controller 2, a hallway light 3, a wall-embedded slave unit 4, a repeater 5, a handheld slave unit 6, and It is configured to include a transmission type handset 7 (corresponding to a nurse call handset and a nurse call device in the claims). The nurse call base device 1 may be installed at a nurse station, or may be a portable nurse call base device carried by each nurse. The wall-embedded handset 4, the repeater 5, the hand-held handset 6, and the message transmitting handset 7 are installed in the patient's hospital room.

The nurse call base unit 1 is used to respond to calls from a patient (hand type handset 6 or message transmission type handset 7), and is used by a nurse to communicate with the patient. The nurse call base unit 1 performs a predetermined notification operation when receiving a call from a patient. The notification operation is performed by outputting a ringing tone from a speaker included in the nurse call base device 1 and displaying information such as the patient related to the call and the call type on the display provided in the nurse call base device 1.

If the nurse performs a response operation such as going off-hook while performing this notification operation, the nurse call main device 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 a call from the hand-type handset 6, the nurse call main unit 1 forms a communication path with the hand-type handset 6 and communicates with the patient. Make it possible to do so. In addition, when a response operation is performed to a call from the business transmission handset 7, the nurse call base unit 1 forms a communication path with the repeater 5, and receives the call from the repeater 5. Receives synthesized speech and outputs it from the speaker.

The controller 2 is disposed between the nurse call base unit 1 and the hallway light 3, and controls communications and data transmission and reception. The transmitted and received data includes a call signal sent from the hand-type handset 6 or the job transmission type handset 7 to the nurse call base unit 1, and a response notification sent from the nurse call base unit 1 to the business job transmission type handset 7. This includes signals, synthesized voice audio signals sent from the repeater 5 to the nurse call base unit 1, and the like.

Corridor lights 3 are installed outside near the entrance of each patient room in the hospital. This hallway light 3 is equipped with a display device, and displays the names of patients in the hospital room, and when a patient in the hospital room calls a nurse using a hand-type handset 6 or a message-transmitting handset 7. , it is now visible that the call was made. Note that the fact that a call has been made may be indicated by lighting or blinking an LED. The LED turns off when a predetermined recovery operation is performed.

The hallway light 3 transmits a call signal transmitted from the hand-type handset 6 or the job transmission type handset 7 via the repeater 5 to the nurse call main unit 1 via the controller 2. In addition, the hallway light 3 transmits a response notification signal transmitted from the nurse call base unit 1 via the controller 2 to the job transmission type slave unit 7 via the wall-embedded slave unit 4 and the repeater 5. do. In addition, the hallway light 3 is connected to an audio signal transmitted from the repeater 5 via the communication path formed by the response operation on the nurse call base unit 1 (the patient's call voice input from the microphone of the hand-type handset 6). , or related to synthesized speech for transmitting business matters generated by the repeater 5) to the nurse call base unit 1 via the controller 2, and from the nurse call base unit 1 via the controller 2. The voice signal related to the voice of the nurse sent by the nurse 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 in the wall of each bedside in the hospital room. This wall-embedded slave unit 4 is connected to the hallway light 3. The wall-embedded slave unit 4 includes a connection terminal for connecting a repeater 5 or a hand-held slave unit 6. Although it is possible to directly connect the hand-held handset 6 to the wall-embedded handset 4, in this embodiment, a repeater 5 is connected to the wall-embedded handset 4, and the hand-held handset is connected to the repeater 5. The form child device 6 is connected. The wall-embedded handset 4 transmits and receives the above-mentioned calling signal, response notification signal, and audio signal between the hallway light 3 and the repeater 5. Note that the wall-embedded handset 4 may include a call button for the patient to call the nurse, and a microphone and speaker for the patient to use when talking with the nurse.

The hand-type slave device 6 is connected to the wall-embedded slave device 4 or the repeater 5, and is installed at the patient's bedside. As mentioned above, the hand-type slave unit 6 can be directly connected to the wall-embedded slave unit 4, but in this embodiment, the hand-held slave unit 6 can be directly connected to the wall-embedded slave unit 4. A hand type handset 6 is connected. The hand-type handset 6 includes a call button 6a for the patient to call the nurse, a microphone (not shown) and a speaker 6b for the patient to use when talking with the nurse.

The hand-type handset 6 is equipped with call buttons 6a corresponding to one or more call types, and when the patient operates any of the call buttons 6a, a call signal of the call type corresponding to the operated call button 6a is emitted. is transmitted to the nurse call base unit 1 via the repeater 5, the wall-embedded handset 4, the hallway light 3, and the controller 2. The call type is, for example, a general call, an emergency call, or a specific call (toilet or intravenous drip).

The task transmission handset 7 is wirelessly connected to the repeater 5 and installed at the patient's bedside. For example, the business transmission type handset 7 is connected to the repeater 5 using Bluetooth (registered trademark) wireless communication means. The business transmission type handset 7 and the repeater 5 perform wireless communication on a one-to-one basis. In performing wireless communication, the repeater 5 performs pairing registration with the business transmission type handset 7. The repeater 5 has the function of performing processing related to pairing registration. For example, after long-pressing the setting switch 5a of the repeater 5 to enter the pairing standby state, by performing a predetermined operation on the task transmission type slave device 7 to be paired, the message transmission type slave device 7 can be activated. Pairing registration is performed by wirelessly transmitting identification information to the repeater 5 and storing this identification information in the repeater 5.

The job transmission type handset 7 includes a plurality of job buttons 7a for the patient to call a nurse, and when the patient operates any job button 7a, the operated job button 7a is identified. A calling signal containing possible button identification information is sent to the repeater 5. The task transmission type handset 7 has a built-in battery and operates by obtaining power from the battery. In this embodiment, the repeater 5 is provided with a pairing registration function and a voice synthesis function, which will be described later, to suppress battery consumption of the business transmission type handset 7.

The repeater 5 is installed between the business transmission type handset 7 and the nurse call base unit 1 (specifically, between the business transmission type handset 7 and the wall-embedded handset 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 calling signal, response notification signal, and voice signal between the wall-embedded handset 4, the hand-held handset 6, and the message transmission handset 7. Regarding the audio signal, the repeater 5 generates a synthesized voice corresponding to the button identification information included in the calling signal received from the business transmission type handset 7, and transfers the generated synthesized voice audio signal to the wall-embedded device. It is transmitted to the nurse call main unit 1 via the device 4, the hallway light 3, and the controller 2. Details of this operation will be described later.

FIG. 2 is a diagram showing an example of the external configuration of the business-transfer type handset 7. As shown in FIG. As shown in FIG. 2, the task transmission type handset 7 includes a plurality of task buttons 7a. In this embodiment, eight task buttons 7a are arranged, four on each side of the front of the housing. Each job button 7a is written with words that concisely represent the content of the job that the patient is transmitting to the nurse. In the example in Figure 2, the words "toilet", "painful", "medication", "tube feeding", "pain", "take phlegm", "intravenous drip", and "errands" each contain eight words. are written on the respective button 7a.

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

As mentioned above, the task button 7a is made of a translucent material, so when the LED on the back side lights up, the pressed task button 7a appears to glow, making it easy to see which task button 7a was pressed. can be seen at a glance. That is, by lighting up the LED corresponding to the pressed job button 7a, the content of the job corresponding to the pressed job button 7a (the content of the wording written on the job button 7a) can be identified. The state will be as shown in . In the following description, the fact that the LED arranged on the back side of the business button 7a is turned on or off is referred to as "the business button 7a is turned on or off" for convenience.

The task transmission type handset 7 includes a lighting switch 7b. The light switch 7b can also be operated by pressing the light switch 7b, and when the patient presses the light switch 7b, all the task buttons 7a light up. For example, after the lights in the hospital room have been turned off at night, by pressing the light switch 7b when the wording of the task written on the task button 7a is not visible, all the task buttons 7a are illuminated and the message is displayed. You can check the contents. Note that the display control unit (described later) provided in the task transmission type handset 7 has an adjustment function that lights up the LED at two levels of brightness, and when the lighting switch 7b is pressed, all the tasks are The button 7a is turned on at low brightness. Furthermore, when any of the job buttons 7a is pressed, the display control section lights up the pressed job button 7a with high brightness.

The task transmission type handset 7 is equipped with a response display lamp 7c. This response display lamp 7c is a lamp for informing that the nurse has responded to the call made by pressing the job button 7a. This response display lamp 7c also has a structure in which an LED is arranged on the back side of a transparent material. When the nurse performs a response operation on the nurse call base device 1, a response notification signal is transmitted from the nurse call base device 1 to the job transmission type slave device 7. Then, when the business transmission type handset 7 receives this response notification signal, the response display lamp 7c lights up. Thereby, the patient can check whether the nurse has responded to the call made by pressing any of the job buttons 7a.

In this embodiment, if the patient notices that he or she has pressed the wrong button 7a before the nurse responds (before the response display lamp 7c lights up), the patient can press the correct button 7a again. It is possible to switch to the call corresponding to the message button 7a. In this case, the display control section turns off the message button 7a that was pressed first, and lights up the message button 7a that was pressed again later. As a result, if the nurse presses the job button 7a again before responding, only one job button 7a is lit.

In addition, if an additional task occurs after the nurse responds (after the response display lamp 7c lights up), the patient can respond to the other task button 7a by pressing the other task button 7a. It is possible to make additional calls to do so. In this case, the display control section keeps the first pressed business button 7a lit, and additionally lights up the second pressed business button 7a. Accordingly, when the nurse presses another task button 7a after responding, a plurality of task buttons 7a are lit.

Note that the display of the response display lamp 7c can be made as follows. For example, if another message button 7a is additionally pressed after the nurse responds (after the response display lamp 7c is lit), the response display lamp 7c is temporarily turned off, and then the message transmission type button 7a is pressed. The response display lamp 7c may be turned on again when the device 7 receives the response notification signal. Alternatively, after lighting the response display lamp 7c for a predetermined period of time from the time when the business transmission type handset 7 receives the response notification signal, the response display lamp 7c is turned on regardless of whether another business button 7a is pressed. The light may be turned off automatically.

The job transmission type handset 7 includes a recovery button 7d for the nurse to operate. In order to prevent the patient from accidentally operating the recovery button 7d, the recovery button 7d is arranged on the top surface of the case, which is different from the front surface of the case where the task button 7a and the light switch 7b, which are operated by the patient, are arranged. There is. This recovery button 7d is a button for turning off the business button 7a pressed by the patient and putting it into a 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 handset is installed), the task button pressed by the patient can be restored. It is possible to release the lighted state of 7a and return the task transmission type handset 7 to the recovery state.

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

As shown in FIG. 3, the nurse call main unit 1 according to the present embodiment has a functional configuration including a calling signal receiving section 101, a notification processing section 102, a response operation detecting section 103, a communication path forming section 104, and a synthesized voice receiving section 105. and a synthesized speech output section 106. The nurse call base device 1 also includes a speaker 111 and a display 112 as a hardware configuration.

The repeater 5 according to this embodiment includes a calling signal relay section 501, a response notification relay section 502, a communication path related processing section 503, a synthesized speech generation section 504, and a synthesized speech transmission section 505 as functional configurations. Further, the repeater 5 includes an audio data storage section 511 as a storage medium. The business transmission type handset 7 according to the present embodiment includes a press detection section 701, a call signal transmission section 702, a display control section 703, and a response notification reception section 704 as functional configurations.

Each of the functional blocks included in the nurse call base unit 1, repeater 5, and job transmission type handset 7 can be configured by hardware, a DSP (Digital Signal Processor), or software. For example, when configured by software, each of the functional blocks described above is actually configured with a computer's CPU, RAM, ROM, etc., and is realized by operating a program stored in the RAM or ROM. Note that the program may be stored in other storage media such as a hard disk or a semiconductor memory.

The press detection unit 701 of the job transmission type handset 7 detects the press of the job button 7a and the light switch 7b by the patient. Further, the press detection unit 701 detects the press of the recovery button 7d by the nurse. When the press detection unit 701 detects a press of the business button 7a by the patient, it notifies the call signal transmission unit 702 and the display control unit 703 of this fact. When the press detection unit 701 detects that the light 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 of this fact.

The call signal transmitter 702 transmits a call signal including button identification information that can identify the pressed job button 7a to the repeater 5 in response to the press of the job button 7a. Note that the button identification information corresponding to each business button 7a is stored in advance in a storage medium (not shown) of the business transmission type handset 7.

The display control unit 703 controls the display of the business button 7a and the response display lamp 7c. That is, when the press detection unit 701 detects that the lighting switch 7b is pressed, the display control unit 703 lights up all the task buttons 7a at low brightness. For example, the display control unit 703 lights up all the job buttons 7a at low brightness for a certain period of time after the lighting switch 7b is pressed, and then turns off all the job buttons 7a. Alternatively, the display control unit 703 lights up all the job buttons 7a in response to pressing the lighting switch 7b, and then turns off all the job buttons 7a when the lighting switch 7b is pressed again. Alternatively, when any of the job buttons 7a is pressed, the job buttons 7a other than the pressed job button 7a may be turned off.

Further, when any of the job buttons 7a is pressed by the press detection unit 701, the display control unit 703 lights up the pressed job button 7a with high brightness, thereby displaying the pressed job button 7a. 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 manner. Further, when the press detection unit 701 detects that the recovery button 7d has been pressed, the display control unit 703 turns off the lit business button 7a (cancels the display state). Furthermore, when the response notification receiving unit 704 receives the response notification signal sent from the nurse call base device 1, the display control unit 703 lights up the response display lamp 7c.

As described above, the response notification receiving unit 704 receives the response notification signal sent from the nurse call base unit 1 via the repeater 5, and notifies the display control unit 703 of this fact. The response notification signal received by the response notification receiving unit 704 is a signal generated when the nurse performs a response operation on the nurse call base unit 1 after the nurse is called by pressing the job button 7a. be. 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 controls the lighting of the task button 7a as follows. to control.

That is, if the other job button 7a is pressed before the response notification receiving unit 704 receives the response notification signal corresponding to the press of the first job button 7a, the display control unit 703 controls the first job button 7a. The message button 7a is turned off (equivalent to canceling the display state in which the contents of the message are displayed in an identifiable manner), and the other message buttons 7a are turned on (the contents of the message are displayed in an identifiable manner). (equivalent to setting the display state). At this time, the calling signal transmitting unit 702 retransmits the calling signal in response to pressing of another task button 7a (hereinafter, this state will be referred to as a retransmission state upon re-pressing).

In addition, after the response notification receiving unit 704 receives the response notification signal corresponding to the pressing of the one task button 7a and before the pressing of the recovery button 7d, the display control section 703 controls the display of the other task button 7a. When button 7a is pressed, the other job button 7a is turned on while the one job button 7a remains lit. At this time as well, the calling signal transmitting unit 702 retransmits the calling signal in response to pressing of another task button 7a (hereinafter, this state will be referred to as an additional pressing retransmission state).

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

Further, when the calling signal relay unit 501 receives the calling signal transmitted by the calling signal transmitting unit 702 of the business transmission handset 7, the calling signal relay unit 501 notifies the synthetic voice generating unit 504 of the button identification information included in the calling signal. At the same time, the call signal is relayed to the nurse call base unit 1 as a call signal of one specific call type (button identification information is not included). When the calling signal relay unit 501 receives a calling signal from the business transmission type handset 7, the calling signal relay unit 501 transmits the call signal regardless of the content of the button identification information included in the calling signal (that is, depending on which business button 7a is pressed). 1), the call signal is relayed to the nurse call base unit 1 as a call signal of a specific call type (for example, general call) among a plurality of call types.

That is, the task buttons 7a for "toilet" and "intravenous drip" shown in FIG. 2 are generally assigned a call type of special call, and the task buttons 7a for "pain" and "pain" Generally, the call type ``emergency call'' may be assigned, but even when these job buttons 7a are pressed, the call signal relay unit 501 changes the call signal of the general call to a nurse call. Send to base unit 1.

As described above, when the call signal relay unit 501 receives a call signal from the hand-type handset 6, the call signal relay unit 501 transmits the call signal to the nurse call main unit as a call signal of the call type corresponding to the pressed call button 6a. Relay to 1. On the other hand, when the call signal relay unit 501 receives a call signal from the job transmission handset 7, it relays the call signal to the nurse call base unit as a call signal of a specific call type. In this way, in this embodiment, one of the call types prepared in the nurse call system is used to send a call signal to the nurse call main unit 1 when transmitting the patient's business to the nurse using synthesized voice. I'm trying to be able to do that.

Regarding the call signal received by the call signal relay unit 501 in the retransmission state when pressing again, the button identification information included therein is only notified to the synthesized voice generation unit 504, and the call signal of the first call type is nurse. The call may not be relayed to base unit 1. In the retransmission state when pressing again, the nurse has not responded yet, so the notification operation continues on the nurse call base unit 1, and even if the call signal is retransmitted, the call type and patient information are not displayed. This is because the contents of the notification operation to be performed will not change as a result. Note that whether or not the call signal received by the call signal relay unit 501 was retransmitted in the push-resend state is determined before the response notification relay unit 502 receives the response notification signal from the nurse call base unit 1. This can be determined based on whether or not the calling signal relay unit 501 has re-received the calling signal from the job transmission handset 7.

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

When a response operation is performed on the nurse call base unit 1 in response to a call from the hand-type handset 6, the call path related processing unit 503 cooperates with the call path forming unit 104 of the nurse call base unit 1. , performs the necessary processing to form a communication path between the nurse call base unit 1 and the hand-type handset 6. For processing in this case, the hand-shaped handset 6 is also equipped with a communication path-related processing section, but it is not shown. Further, when a response operation is performed on the nurse call base unit 1 to a call from the business transmission type handset 7, the call path related processing unit 503 communicates with the call path forming unit 104 of the nurse call base unit 1. They cooperate to perform the necessary processing to form a communication path between the nurse call base unit 1 and the repeater 5. When a communication path is formed between the nurse call base device 1 and the repeater 5, the communication path related processing unit 503 notifies the synthesized speech generation unit 504 to that effect.

When a communication path is formed between the nurse call base unit 1 and the repeater 5, the synthesized voice generation unit 504 generates a button included in the call signal that the call signal relay unit 501 receives from the job transmission type handset 7. The voice data corresponding to the identification information is read from the voice data storage unit 511 to generate synthesized voice. The audio data storage unit 511 stores a plurality of audio data corresponding to multiple types of synthesized voices and button identification information in association with each other. The plurality of types of synthesized speech indicate the content of the business that the patient conveys to the nurse.

FIG. 4 is a diagram schematically showing the contents of synthesized speech corresponding to a plurality of pieces of speech data stored in the speech data storage unit 511 according to this embodiment and the association with button identification information. The eight synthesized voices shown in FIG. 4 correspond to the eight task buttons 7a shown in FIG. 2. In other words, there are 8 items with the following words: ``toilet,'' ``pain,'' ``medication,'' ``tube feeding,'' ``pain,'' ``take phlegm,'' ``intravenous drip,'' and ``errands.'' Audio data for generating eight synthesized voices shown in FIG. 4 is stored in the audio data storage unit 511 in association with the button identification information “001” to “008” of the button 7a. For example, a synthesized voice saying "I want to go to the toilet" is associated with the button identification information "001" corresponding to the first task button 7a located at the upper left corner of the case of the task transmission handset 7. voice data is stored. In addition, in association with the button identification information "008" corresponding to the eighth task button 7a located at the bottom right of the case of the task transmission handset 7, a synthesized voice saying "I have something to do." Audio data is stored.

After a communication path is formed between the nurse call base unit 1 and the repeater 5, the synthesized voice transmitting unit 505 transmits a button included in the call signal received from the job transmission type handset 7 by the call signal relay unit 501. A synthesized voice (synthesized voice generated by the synthesized voice generation unit 504) according to the identification information is transmitted to the nurse call base unit 1 via the communication path. As described above, when a communication path is formed between the nurse call base unit 1 and the repeater 5 in response to a call signal from the job transmission handset 7, the synthetic voice generation unit 504 generates a call signal from the call signal. A synthesized voice is generated by reading voice data corresponding to the button identification information included in the voice data storage section 511. The synthesized voice transmitter 505 transmits the voice signal of the synthesized voice generated by the synthesized voice generator 504 to the nurse call base unit 1 . Note that in the following description, "synthesized speech is transmitted" may be used, but this is synonymous with "synthesized speech audio signal is transmitted".

In this way, in this embodiment, by using a limited number of call types prepared in the nurse call system, the nurse uses a synthesized voice to convey more types of business than the number of call types to the nurse. The call can be sent to base unit 1. In this embodiment, it is possible to transmit synthesized voices of eight types of business to the nurse call base unit 1 using one call type, for example, a general call.

The call signal receiving unit 101 of the nurse call base unit 1 receives the call signal from the hand-type handset 6 and the call signal from the job transmission type handset 7 relayed by the call signal relay unit 501 of the repeater 5. . The notification processing unit 102 performs a predetermined notification operation in response to reception of the calling signal by the calling signal receiving unit 101, and stops the notification operation in response to a predetermined response operation detected by the response operation detection unit 103. That is, when the paging signal receiving section 101 receives a paging signal, the notification processing section 102 outputs a paging tone from the speaker 111 and causes the display 112 to display information such as the patient and the type of paging related to the paging. Execute notification operation. Thereafter, when the response operation detection unit 103 detects a response operation such as off-hook, the notification processing unit 102 stops the above-mentioned notification operation and transmits a response notification signal to the repeater 5.

The communication path forming unit 104 forms a communication path with the repeater 5 or the hand-type handset 6 when the press detection unit 701 detects a response operation to the notification operation performed in response to receiving the calling signal. . That is, when the press detection unit 701 detects a response operation to the notification operation performed in response to the calling signal from the hand-type handset 6, the communication path forming unit 104 creates a communication path between the hand-type handset 6 and the notification operation. Perform processing to form. Further, when the press detection unit 701 detects a response operation to the notification operation performed in response to the calling signal from the business transmission type handset 7, the communication path forming unit 104 creates a communication path between the relay unit 5 and the relay device 5. Perform processing to form.

The synthesized voice receiving unit 105 receives the voice signal of the synthesized voice sent from the repeater 5 via the communication path formed by the communication path forming unit 104. The synthesized voice output unit 106 outputs the synthesized voice of the business from the speaker 111 based on the voice signal of the synthesized voice received by the synthesized voice receiving unit 105 . By listening to the synthesized voice output from the speaker 111, the nurse can understand the business matters conveyed by the patient without having to talk to the patient.

FIG. 5 is a flowchart showing an example of the operation of the nurse call system according to this embodiment configured as described above. The flowchart in FIG. 5 shows an example of the basic operation regarding output processing of synthesized speech executed when the patient presses any of the task buttons 7a, and display control of the task button 7a and the response display lamp 7c (when pressed again). An example of the operation when neither the retransmission state nor the additional press retransmission state is shown, and operations related to other processes are omitted. In addition, in the flowchart shown in FIG. 5, the description of the operations of the controller 2, the hallway light 3, and the wall-embedded slave device 4 is omitted.

First, when the press detection unit 701 detects that any of the job buttons 7a have been pressed by the patient (step S1), the display control unit 703 lights up the pressed job button 7a (step S2). Further, the calling signal transmitting unit 702 transmits a calling signal including button identification information that can identify the pressed business button 7a to the repeater 5 (step S3). The call signal relay unit 501 of the repeater 5 receives the call signal transmitted by the call signal transmitter 702, and relays it to the nurse call base unit 1 as a call signal of a specific call type (step S4).

The call signal receiving unit 101 of the nurse call base unit 1 receives the call signal sent from the job transmission type handset 7 via the repeater 5, the wall-embedded handset 4, the hallway light 3, and the controller 2.

The notification processing unit 102 performs a predetermined notification operation in response to the reception of the calling signal by the calling signal receiving unit 101 (step S6). During this notification operation, the response operation detection unit 103 monitors whether or not the nurse performs a response operation (step S7).

If the response operation detection unit 103 detects a response operation by the nurse, the notification processing unit 102 stops the notification operation (step S8). In response, the notification processing unit 102 transmits a response notification signal to the repeater 5 (step S9). Further, the communication path forming unit 104 forms a communication path with the repeater 5 (step S10). The response notification relay unit 502 of the repeater 5 receives the response notification signal sent from the nurse call base device 1, and relays it to the business transmission type slave device 7 (step S11).

The response notification receiving unit 704 of the business transmission type handset 7 receives the response notification signal relayed by the response notification relay unit 502, and notifies the display control unit 703 of this (step S12). Upon receiving this notification, the display control unit 703 turns on the response display lamp 7c for a certain period of time, and then turns it off (step S13).

When the communication path between the nurse call base unit 1 and the repeater 5 is formed by the process of the communication path forming unit 104 in step S10, the synthetic voice generation unit 504 of the repeater 5 relays the calling signal in step S4. The unit 501 reads out audio data corresponding to the button identification information included in the calling signal received from the job transmission handset 7 from the audio data storage unit 511, and generates a synthesized voice (step S14).

Next, the synthesized voice transmitting unit 505 transmits the voice signal of the synthesized voice generated by the synthesized voice generating unit 504 to the nurse call base unit 1 (step S15). In the nurse call base unit 1, the synthesized voice receiving unit 105 receives the synthesized voice voice signal transmitted from the repeater 5 (step S16), and the synthesized voice output unit 106 generates a synthesized voice based on the synthesized voice voice signal. is output from the speaker 111 (step S17). By listening to the synthesized voice output from the speaker 111, the nurse can grasp the business message being conveyed by the patient. The nurse then heads to the ward where the call was made in order to perform nursing duties corresponding to the request.

After turning on the response display lamp 7c in step S13, the task transmission type handset 7 monitors whether the recovery button 7d has been pressed (step S18). When the nurse who has arrived at the hospital room presses the recovery button 7d and the press detection section 701 detects this, the display control section 703 turns off the task button 7a that was lit in step S2 (step S19).
