  FIG. 2 shows a block diagram of the corridor light 2. As shown in FIG. 2, the corridor light 2 is an indicator light 21 that blinks when a patient in the patient room operates the cordless handset 1 to call a nurse, and a patient name and the like in the patient room. An information display unit 22, a microphone 23 and a speaker 24, an acoustic circuit 25 that controls the microphone 23 and the speaker 24 to generate an alarm sound, a word information storage unit 26 that stores a specific word, a specific word that detects a specific word from voice. The detection unit 27, a corridor lamp CPU 28 that controls the corridor lamp 2, a corridor lamp communication IF 29 that communicates with the child device 1 and the controller 7, and the like.

  The specific word is a word that serves as a trigger for starting the storage of voice information, and the word information storage unit 26 and the specific word detection unit 27 may be provided in the plate slave unit 1b. A microphone (not shown) is also provided in the ceiling speaker 8, and the corridor light 2 connected via the transmission line L3 also manages this audio information.

  The main|base station 3 is equipped with the 1st display part 3a which displays various information including the list of patient information, the 2nd display part 3b which displays caller information, the handset 3c for answering a call, etc.

FIG. 3 shows a block diagram of the controller 5. As shown in FIG. 3, the controller 5 includes a nursing system information storage unit 51, a patient-related information storage unit 52, a voiceprint information storage unit 53 that stores voiceprint information of each nurse, a voiceprint determination unit 54, and voice data as text data. The entire controller including a text conversion unit 55 for converting into a voice, a voice information storage unit 56 for storing voices, text data, etc., a microphone location storage unit 57 in which the location of each microphone is registered, and saving control to the voice information storage unit 56.

The nursing system information storage unit 51 stores nurse information (information on patients in charge of individual nurses, allocation information on the mobile terminal 4, etc.), doctor information in charge, and the like. In addition, the patient-related information storage unit 52 stores the patient room number, bed number information, and the like.

The nurse call system configured as described above operates as follows. However, the operation of operating the child device 1 to call the nurse to call is the same as in the prior art, and therefore the description thereof is omitted. The operation as a system will be mainly described. This function is mainly applied when the patient spits out to the nurse.
As an example, a case in which a patient in the sickroom No. 201 utters an assault to the nurse near the slave 1 with the slave number 010 will be specifically described. Further, it is assumed that the word information storage unit 26 stores the word “code white” as a specific word. It should be noted that this specific word may be any word that is not frequently used by the nurse.

  The microphone 11 of the cordless handset 1 is always in an active state, and the specific word detection unit 27 constantly analyzes the voice collected by the microphone 11. In this state, when the nurse, who feels a danger that the patient speaks abusively to the nurse who is in room 201 and is treating the patient, issues the specific word "code white", the microphone 11 collects it. Upon sounding, the specific word detecting unit 27 recognizes that the specific word is emitted.

When the specific word is recognized, whether the voice is a voice of a nurse or not, voice information is transmitted to the controller 5, and the voiceprint discriminating unit 54 compares the voice information with the data in the voiceprint information storage unit 53 under the control of the controller CPU 58. It is determined whether it is the teacher's voice.
When it is determined that it is the voice of the registered nurse, the collection of the collected voice of the microphone 11 is started, and the voice is stored in the voice information storage unit 56 together with the date and time information.
Also, the location is read from the microphone location storage unit 57 based on the ID information of the microphone 11 attached to the transmitted voice information, and the location is recognized as the 010 child machine of the hospital room 201, and the information of the hospital room number and the bed number is matched. Saved.

  Furthermore, the voice is converted into text data in the text conversion unit 55, and the voice information is linked to the voice information and stored in the voice information storage unit 56, and the nurse information specified from the voiceprint information is also stored. By converting it into text and saving it, you can understand the content of the uttered voice with text information without playing the voice, it is easier to understand the spoken content, it is easier to search for words, and it is easier to organize the saved information ..

  Further, at the start of saving, a notification sound for starting recording is issued from the speaker 12 of the slave unit 1 of the slave unit number 010 in the room 201 under the control of the controller CPU 58. The notification sound may be sound information such as a tap sound such as “pawn”, but the message may be stored in the handset 1 and the message may be reported. By this notification, the nurse can recognize that the voice storage has started and can deal with it with peace of mind.

  The voice information is stored for a predetermined time such as 60 seconds and ends when the time elapses, but may end at the time when the voice is interrupted for a fixed time such as 20 seconds. Further, even if the specific word is detected, the voice storage is not started unless the nurse who matches the analyzed voice print is registered.

The above has described the flow of storing the voice uttered by the patient in the hospital room, but the voice uttered by the patient is also stored in the common areas such as the corridor and the common room. For example, voice storage in the corridor is performed as follows.
As an example, a case will be described in which a patient utters an assault to a nurse in the corridor in front of the sickroom 201. The microphone 23 of the corridor lamp 2 is always in an active state, and the specific word detection unit 27 is always analyzing the voice collected by the microphone 23, like the microphone 11 of the slave 1. In this state, the patient in front of room 201 uttered abusive words at the approaching nurse, and when the nurse who sensed the danger uttered a trigger voice "code white", it was collected by the microphone 23 of the corridor light 2. The specific word detector 27 recognizes the sound.

When the specific word serving as the trigger is recognized, the voice information is transmitted to the voice print determination unit 54 of the controller 5 to determine whether the voice is the voice of the registered nurse, as in the detection operation in the hospital room. When it is determined that it is the voice of the registered nurse, the control unit CPU 58 controls the storage of the collected voice of the microphone 23, and the voice information is stored in the voice information storage unit 56 together with the date and time information.
Further, the location is read from the microphone location storage unit 57 based on the ID information of the microphone 23 attached to the transmitted voice information, the location is recognized as the corridor light 2 in front of the hospital room 201, and the information of the corridor light 2 is also stored. To be done.

  Then, as in the case of the sick room, the voice is converted into text data in the text conversion unit 55, stored in the voice information storage unit 56 in association with the voice information, and the nurse information specified from the voice print information is also stored. It is saved together. Further, when the storage is started, a notification sound for starting recording is output from the speaker 24 of the corridor lamp 2 under the control of the controller CPU 58.

  It should be noted that the storage control of the voice information is similarly performed in the other common parts. For example, in a place where there is no corridor light such as a common room, sound is collected by a microphone provided in the ceiling speaker 8. This collected sound is transmitted to the nearby corridor lamp 3 connected via the transmission line L3, a specific word is detected, and the subsequent operation is the same as when the microphone 23 of the corridor lamp 3 collects sound. Yes, if the collected voice satisfies a specific condition, storage control of voice information is performed.

In this way, when the specific word is issued, the voice storage is started, so that the situation can be stored when the nurse receives abusive words from the patient. Therefore, voice information can be left as evidence without stimulating the patient. Moreover, since the voice is not always saved, the privacy of the patient can be taken into consideration.
In addition, even if a specific word is detected from the voice collected by the microphone, if it is not the voice uttered by the nurse, the saving operation does not occur, so malfunctions can be prevented and the information of the nurse who was there is also associated with the voice. Since it is saved after being saved, it is possible to know to whom the rant is against and it is easy to deal with it.
Further, although the start of saving the voice requires a specific word, the end of the save is automatically performed, so that the voice information can be efficiently saved.
In addition, since location information such as patient rooms is stored together with voice information, it is easy to identify and manage patients, and by constructing a voice information storage system using the function of the nurse call system, a voice information storage system can be inexpensively manufactured. Can be built.

  Although the voiceprint information storage unit 53, the voiceprint determination unit 54, the text conversion unit 55, and the voice information storage unit 56 are provided in the controller 5 in the above embodiment, some or all of them may be provided in the parent device 3. good. Further, the configuration in which the mechanism of the voice information storage system is provided in the nurse call system installed in the hospital has been described, but the present invention is not limited to the hospital, and can be easily applied to a facility where a care receiver moves in.
