Description

  The present invention relates to a nurse call system for calling a medical staff such as a nurse from a patient, and more particularly, to a nurse call system having a listening function for a medical staff to check a patient's condition.

  In general, a nurse call system has a nurse call slave unit having a call operation unit installed in the vicinity of each bed in each room, and a nurse call master unit at a nurse station where nurses and other medical staff are resident. It is installed. When the patient operates the call operation unit of the nurse call slave, a call signal is output from the nurse call slave to the nurse call master and the call is notified by the nurse call master that has received the call signal. It is configured as follows. Here, the nurse call system is used not only in a hospital but also in a nursing facility.

  A nurse call master unit is known that has a board shape in which a tuning unit having a lamp such as an LED (light-emitting diode) and a display field for displaying a patient's name is combined according to the number of patients. The board-shaped nurse call parent device is attached to a wall surface of the nurse station, and the medical staff in the nurse station can browse information displayed on the board-shaped nurse call parent device. Here, in the nurse call master device to which the call signal output from the nurse call slave device is input, the nurse call slave device that is included in the call signal and called by the slave device identification information for identifying the nurse call slave device. Is identified. And the notification of a call is performed by lighting or blinking the lamp | ramp of the channel selection part corresponding to the patient who is using the specified nurse call cordless handset. Further, the call notification is performed not only by lighting / flashing of the lamp of the tuning unit but also by sound output from the speaker.

  As described above, when a call is notified by the nurse call parent machine, a medical worker who notices the call needs to respond. For this reason, the nurse call master unit is provided with a handset for responding to a call notification. When a caller is alerted and a health care worker off-hooks the handset, call alerting stops and the nurse call master and the nurse call slave (or the room where the nurse call slave is installed) A communication path is formed between them. Here, since the nurse call cordless handset (or hospital room) is provided with a speaker and a microphone for a call, a call can be made between the patient and a medical worker.

  By the way, using the fact that a call can be made between a nurse call slave unit and a nurse call master unit, any nurse call slave unit or all nurse call slave units are selected and the selected nurse call slave unit is selected. There is known a technique for listening to a patient's condition by outputting a voice input from a microphone provided in a speaker from a speaker provided in a nurse call master (for example, Patent Document 1). According to the technology described in Patent Document 1, the nurse call slave units selected by the bed selection button are sequentially switched, and the voice input from the nurse call slave unit is output from the speaker of the nurse call master unit. ing.

  On the other hand, when a patient in a hospital room makes a loud voice, the voice is input to a microphone installed on the ceiling, and when the input voice is above a certain level, between the patient room and the nurse call master unit A technique is also known in which a medical worker can confirm the state of a patient in a hospital room by forming a communication path (for example, Patent Document 2). A technique is also known in which a nurse call slave unit outputs a call signal to a nurse call master unit when the level of sound input to the microphone is higher than a certain level.

  However, in the technique described in Patent Document 1, the nurse call slave units selected by the bed selection button are sequentially switched, and the voice input from the nurse call slave unit is output from the speaker of the nurse call master unit. When a patient using a nurse call cordless handset other than the nurse call cordless handset that is actually listening is loud, the medical staff will There was a problem that I couldn't notice the change in the state.

  On the other hand, in the prior art including the technique described in Patent Document 2, when the sound input to the microphone installed on the ceiling is above a certain level, a communication path is formed between the hospital room and the nurse call parent device. Since the nurse call parent machine is informing, if the medical worker is not in the vicinity of the nurse call parent machine, the problem is that the medical worker cannot notice the change in the patient's condition. there were. Here, it is possible for the medical staff to grasp the notification by the mobile terminal by carrying the mobile terminal having the function of the nurse call parent device to the medical staff.

  However, even if a speech path is formed between the hospital room and the mobile terminal, if the mobile terminal does not output sound at a high volume, a medical worker may notice the sound output from the mobile terminal. There was a problem that it was not realistic because it was not. In addition, when a patient makes a loud voice or the like, if the mobile terminal gives notifications one by one, there is a problem that a case where the work of a medical worker who performs other work is hindered occurs.

  The present invention has been made to solve such a problem, and when a medical staff is listening to confirm the patient's condition, the condition of each patient is as long as possible. The purpose is to be able to confirm.

In order to solve the above-described problem, in the present invention, a plurality of selected nurse call slave units are sequentially switched, and the voice input from the microphone of the nurse call slave unit is output from the speaker of the nurse call master unit. The nurse call cordless handset is displayed in an identifiable manner. At this time, the sound level input to the microphone of the nurse call cordless handset that is not outputting sound from the speaker is determined, and when the sound level is equal to or higher than a predetermined level, a plurality of selected The voice output and display from the nurse call cordless handset is interrupted, and the voice input from the nurse call cordless handset whose voice level exceeds the specified level is output from the nurse call master phone speaker, and the nurse call The call slave unit is displayed in an identifiable manner, and the output and display of audio from the interrupted nurse call slave unit or the next nurse call slave unit are resumed after completion .

  According to the present invention configured as described above, when the nurse call slave unit of the selected bed is sequentially switched and the voice input from the nurse call slave unit is output from the speaker of the nurse call master unit, another nurse call unit is output. When a voice of a predetermined level or more is input by the call slave unit, the voice input from the microphone of the nurse call slave unit is output from the speaker of the nurse call master unit. As a result, during the listening when the medical worker is about to check the patient's state, the medical worker can notice a change in the state of all the patients to be listened to. Therefore, during listening, the medical staff can check the status of each patient for as long as possible.

FIG. 1 is a block diagram illustrating a configuration example of a nurse call system according to the present embodiment. The nurse call system shown in FIG. 1 is installed in the vicinity of a patient's bed, and is installed in a nurse call cordless handset 1 used by a patient in a hospital room, a nurse station where a medical worker is resident, and the like. The nurse call parent device 10 is used. Here, the nurse call cordless handset 1 is installed in each hospital room according to the number of beds in the hospital room.

  The nurse call slave unit 1 includes a slave unit control unit 2, a call operation unit 3, a slave unit microphone 4, a slave unit speaker 5, a voice level determination unit (corresponding to the voice level determination device in claims), The machine interface 7 is provided. The nurse call parent device 10 includes a parent device control unit 11, a parent device interface 12, a storage unit 13, an operation unit 14, a notification unit 15, a parent device microphone 16, a parent device speaker 17, and a channel selection unit 18. ing.

  First, each component of the nurse call handset 1 will be described. The subunit | mobile_unit control part 2 is for controlling each component of the nurse call subunit | mobile_unit 1 so that it may mention later, and is comprised by CPU (Central Processing Unit) etc. The call operation unit 3 is for operation when a patient calls a medical worker, and includes a call button and the like. The patient operates the call operation unit 3 when he / she wants to call a medical worker. Then, the subunit | mobile_unit control part 2 produces | generates a calling signal. Here, the call signal includes slave unit identification information for identifying the nurse call slave unit 1 from other nurse call slave units 1. In addition, information such as a bed number is used as the slave unit identification information.

  The subunit | mobile_unit microphone 4 inputs the surrounding audio | voice and converts it into an audio | voice signal. The subunit | mobile_unit speaker 5 demodulates the audio | voice signal input from the nurse call main | base station 10, and outputs loudly as an audio | voice. Here, the handset microphone 4 and the handset speaker 5 are controlled by the handset controller 2 to operate.

  The subunit | mobile_unit control part 2 determines whether the listening object signal containing the subunit | mobile_unit identification information of an own apparatus was input from the nurse call main | base station 10. FIG. When the child device control unit 2 determines that the listening target signal including the child device identification information of the own device is input, the child device control unit 2 operates the child device microphone 4. Here, the listening target signal is for notifying that the nurse call handset 1 specified by the handset identification information included in the listening target signal is the target of listening.

  In this state where the handset microphone is operating, the sound level determination unit 6 receives the sound signal converted by the handset microphone 4 and whether the level of the sound signal is equal to or higher than a predetermined level. Determine whether. If the audio level determination unit 6 determines that the level of the input audio signal is equal to or higher than a predetermined level, the audio level determination unit 6 adds interrupt information to the audio signal and controls the slave unit. Output to part 2. The slave unit control unit 2 receives the audio signal to which the interrupt information is added from the audio level determination unit 6, adds the slave unit identification information of its own device, and outputs it to the slave unit interface 7. Therefore, interrupt information and slave unit identification information are added to the audio signal. On the other hand, when the audio level determination unit 6 determines that the level of the input audio signal is less than the predetermined level, the audio level determination unit 6 does not output the audio signal to the child device control unit 2.

  Here, the predetermined level corresponds to a threshold value of an audio signal indicating that the patient is in an abnormal state such as when the patient is loud. The interrupt information is for interrupting when the nurse call master device 10 is listening to a plurality of nurse call slave devices 1 in order.

  The slave unit control unit 2 receives the listening target signal including the slave unit identification information of the own device from the nurse call master unit 10 and receives the listening signal including the slave unit identification information of the own device from the nurse call master unit 10. It is determined whether or not is input. When the child device control unit 2 determines that the listening signal including the child device identification information of its own device has been input, the child device control unit 2 controls the audio level determination unit 6 to control the child device microphone. The audio signal output from 4 is input as it is. Then, the slave unit control unit 2 adds the slave unit identification information of its own device to the voice signal input from the voice level determination unit 6 and outputs it to the slave unit interface 7. Therefore, only the handset identification information is added to the audio signal.

  Here, the listening signal is for notifying the nurse call handset 1 specified by the handset identification information included in the listening signal that the listening is actually being performed. When the handset controller 2 stops inputting the listening signal, the handset controller 2 stops outputting the audio signal input from the sound level determination unit 6 to the handset interface 7.

  The slave unit interface 7 is for connecting the nurse call slave unit 1 and the nurse call master unit 10 for communication. Here, the handset interface 7 outputs the call signal generated by the handset control unit 2 to the nurse call base unit 10. The handset interface 7 outputs the audio signal input from the handset control unit 2 to the nurse call base unit 10. Further, the slave unit interface 7 outputs a voice signal to which the interrupt information input from the slave unit control unit 2 is added to the nurse call master unit 10.

  Between the nurse call cordless handset 1 and the nurse call master phone 10, a corridor lamp (not shown) that displays a call from the nurse call cordless handset 1 or displays the name of a patient in a hospital room is connected. Yes. Further, between the nurse call slave unit 1 and the nurse call master unit 10, a controller (not shown) that performs control related to communication between the nurse call slave unit 1 and the nurse call master unit 10 is connected.

  Next, each component of the nurse call parent machine 10 will be described. The base unit control unit 11 is for controlling each component of the nurse call base unit 10 as will be described later, and includes a CPU and the like. The master unit interface 12 is for connecting the nurse call master unit 10 and the nurse call slave unit 1 for communication.

  Here, the base unit interface 12 inputs the call signal output from the nurse call handset 1. The master unit interface 12 inputs various audio signals output from the nurse call slave unit 1. Here, when the master unit interface 12 receives a voice signal from each nurse call slave unit 1, the master unit control unit 11 analyzes the slave unit identification information added to the voice signal, thereby obtaining the voice. The nurse call cordless handset 1 from which the signal is output is identified.

  The storage unit 13 is configured by a storage device such as a memory or a hard disk drive. The storage unit 13 includes a slave unit identification information of the nurse call slave unit 1 connected to the nurse call master unit 10 and a channel selection unit 20 in the channel selection unit 18 described later. Is stored in association with position information indicating the position of. The operation unit 14 is operated to start listening.

  The alerting | reporting part 15 is for alert | reporting the call from the nurse call subunit | mobile_unit 1, and is comprised by the speaker, the display apparatus, etc. When the base unit interface 12 receives a call signal from the nurse call handset 1, the base unit control unit 11 operates the notification unit 15 to output a notification sound from the speaker or display the notification content on the display device. To make a notification. When a notification is given by the notification unit 15 and a medical worker responds with a handset or the like (not shown), the handset is off-hooked and a communication path is formed between the nurse call master unit 10 and the nurse call slave unit 1. The

  The base microphone 16 inputs ambient sound and converts it into a sound signal. The master speaker 17 demodulates the voice signal input from the nurse call slave unit 1 and outputs it as a voice. Here, the parent device microphone 16 and the parent device speaker 17 are controlled by the parent device control unit 11.

  As shown in FIG. 2, the channel selection unit 18 is formed by combining channel selection units 20 corresponding to the patients vertically and horizontally. Each channel selection unit 20 has a bed number display field 21 for displaying the bed number used by the patient, a name card mounting unit 22 for detachably mounting a name card having at least the name of the patient on the surface, and a selection unit. The selector unit 20 is operated to select the station unit 20 and includes a selection button having translucency, and a selection unit 23 having a lamp such as an LED attached inside the selection button.

  Here, the lamp of the selection unit 23 notifies that there is a call from the patient by blinking in synchronization with the notification of the notification unit 15. Further, since the storage unit 13 stores the positional information of the channel selection unit 20 in association with the slave unit identification information included in the calling signal and the voice signal, the storage unit 13 stores the positional information of the channel selection unit 20 corresponding to the calling patient. Only the lamp of the selection unit 23 that is installed blinks, or only the lamp of the selection unit 23 that is installed in the channel selection unit 20 corresponding to the nurse call handset 1 that is listening is turned on.

  Therefore, when the lamp blinks, the medical worker who sees the name card attached to the bed number display column 21 and the name card attachment unit 22 corresponding to the lamp easily knows which patient has called. be able to. When the lamp is lit, which nurse call cordless handset 1 is being listened to by the medical staff who has seen the name card attached to the bed number display field 21 corresponding to the lamp or the name card attachment unit 22. Can be easily grasped.

  Next, the operation when listening will be described. The parent device control unit 11 of the nurse call parent device 10 determines whether or not the selection unit 23 of the channel selection unit 18 has been operated. The medical staff selects the patient who wants to listen by operating the selection unit 23. In addition, you may make it provide the simultaneous selection part for selecting all the patients simultaneously.

  In this state, base unit control unit 11 determines whether or not operation for starting listening has been performed by operation unit 14. When the selection by the selection unit 23 is completed, the medical staff operates the operation unit 14. Then, the parent device control unit 11 refers to the storage unit 13 and extracts the child device identification information stored in association with the position information of the channel selection unit 20 in which the selection unit 23 is operated. And if the operation part 14 is operated after the several selection part 23 is operated, the main | base station control part 11 will produce | generate the listening object signal containing the some extracted some subunit | mobile_unit identification information.

  The listening target signal generated by the parent device control unit 11 is output to all the nurse call child devices 1 connected to the nurse call parent device 10 through the parent device interface 12. Each nurse call handset 1 inputs a signal to be listened to through the handset interface 7. The handset controller 2 of each nurse call handset 1 determines whether or not the handset identification information included in the listening target signal matches the handset identification information of its own device. When the child device control unit 2 determines that the child device identification information included in the listening target signal matches the child device identification information of the own device, the child device control unit 2 operates the child device microphone 4.

  In this state, the audio level determination unit 6 of each nurse call child device 1 receives the audio signal converted by the child device microphone 4 and determines whether the level of the audio signal is equal to or higher than a predetermined level. To do. If the audio level determination unit 6 determines that the level of the input audio signal is equal to or higher than a predetermined level, the audio level determination unit 6 adds interrupt information to the audio signal and controls the slave unit. Output to part 2. The slave unit control unit 2 receives the audio signal to which the interrupt signal is added from the audio level determination unit 6, adds the slave unit identification information of its own device, and outputs it to the slave unit interface 7. Therefore, interrupt information and slave unit identification information are added to the audio signal. On the other hand, when the audio level determination unit 6 determines that the level of the input audio signal is less than the predetermined level, the audio level determination unit 6 does not output the audio signal to the child device control unit 2.

  In addition, the parent device control unit 11 of the nurse call parent device 10 generates a listening signal according to a predetermined order among a plurality of pieces of child device identification information included in the listening target signal, and outputs the generated listening signal for a predetermined time. The data is output by the base unit interface 12 at intervals. Here, the predetermined order may be the order in which the selection unit 23 is operated or the order of bed numbers. Further, the predetermined time interval is a time for listening to one nurse call handset 1, and is about 30 seconds, for example. That is, the master unit control unit 11 outputs the listening signal including the slave unit identification information of the nurse call slave unit 1 to be listened first, and then outputs the slave unit identification information of the nurse call slave unit 1 to be listened next. A listening signal including is output for 30 seconds. And the main | base station control part 11 performs the operation | movement mentioned above with respect to all the nurse call subunit | mobile_units 1 of listening object.

  In the nurse call cordless handset 1 that has input the listening target signal including the cordless handset identification information of the own device, the cordless handset determines whether or not the listening signal including the cordless handset identification information of the own device is input from the nurse call master set 10. The control unit 2 makes a determination. When the child device control unit 2 determines that the listening signal including the child device identification information of its own device has been input, the child device control unit 2 controls the audio level determination unit 6 to receive the signal from the child device microphone 4. The output audio signal is input as it is. Then, the slave unit control unit 2 adds the slave unit identification information of its own device to the voice signal input from the voice level determination unit 6 and outputs it to the slave unit interface 7.

  The slave unit interface 7 outputs the audio signal input from the slave unit control unit 2 to the nurse call master unit 10. The parent device interface 12 of the nurse call parent device 10 inputs an audio signal from the nurse call child device 1. Then, the base unit control unit 11 analyzes the audio signal input by the base unit interface 12 and determines whether or not interrupt information is included. If interrupt information is not included in the input audio signal, base unit control unit 11 continues to generate the listening signal according to the predetermined order described above. At this time, the base unit control unit 11 outputs a sound signal to the base unit speaker 17, and the base unit speaker 17 converts the input sound signal into sound and outputs it to the outside. Further, the base unit control unit 11 refers to the storage unit 13, acquires the location information stored in association with the slave unit identification information included in the audio signal, and selects the channel selection unit 20 specified by this location information. Are sequentially turned on.

  On the other hand, when the interrupt information is included in the input audio signal, base unit control unit 11 outputs the audio signal to base unit speaker 17, and base unit speaker 17 converts the input audio signal into a sound. Output to the outside. Further, the base unit control unit 11 refers to the storage unit 13, acquires the location information stored in association with the slave unit identification information included in the audio signal, and selects the channel selection unit 20 specified by this location information. The lamp of the selection unit 23 is turned on. In this manner, in a state where the voices input to the slave microphones 4 of the nurse call slave devices 1 are output from the master speaker 17 of the nurse call master device 10 in a predetermined order, other nurses to be listened to When the handset microphone 4 of the call handset 1 receives a sound of a predetermined level or higher, the nurse call base handset 10 listens to the nurse call handset 1 that has input a sound of a predetermined level or higher. .

  In this state, when listening to the nurse call handset 1 that has input a sound of a predetermined level or higher is completed, the base unit control unit 11 resumes listening in a predetermined order. Here, the end of the listening of the nurse call slave unit 1 that has input a sound of a predetermined level or more may be ended by a predetermined time, or may be ended by operating the selection unit 23 of the corresponding channel selection unit 20. You may make it do. In addition, resumption of listening may be resumed from the nurse call slave unit 1 in which the interruption has been performed, or resumed from the nurse call slave unit 1 next to the nurse call slave unit 1 in which the interruption has been performed. May be.
