JP 2004-344538 A

  The nurse call system of Patent Document 1 can display an image of one surveillance camera installed in the hospital and an image captured by the interphone slave camera. However, both cameras are applied to a configuration in which a video signal is transmitted by an NTSC signal, and a transmission line for transmitting a video needs to be independent for each camera. Therefore, when trying to install a plurality of cameras in the hospital, wiring work becomes troublesome and video switching operation becomes troublesome, and the number of cameras is limited.

  Therefore, when installing multiple cameras in the hospital, it is convenient to change the camera to one that outputs digital signals, which makes LAN wiring easy for wiring work possible, but in that case, it is necessary to unify the signal form In addition, an intercom slave unit that outputs a video signal as a digital signal is required. However, since there is no existing interphone slave unit that outputs such a digital signal, a monitoring camera that outputs a digital signal is installed near the interphone slave unit to unify the signals.

  On the other hand, in the case of an intercom system installed in a relatively small hospital, an inexpensive NTSC specification is often used for the monitor. Therefore, in such hospitals, we want to use all cameras with NTSC specifications. However, when a plurality of cameras are to be installed in the hospital as described above, the NTSC specification camera is not preferable, and the interphone device and the nurse call system have been installed independently.

  Therefore, in view of such problems, the interphone slave unit outputs video signals as NTSC signals, and the in-hospital camera outputs digital signals as video signals. The purpose is to provide a nurse call system that can display the video.

  In order to solve the above-mentioned problems, the invention of claim 1 is configured such that a nurse call slave set installed in each bed of a hospital room and having a function for a patient to call a nurse and make a call is connected to the nurse call slave set. Controls the communication between the nurse call master unit and the nurse call master unit, which is installed in the nurse station and responds to calls from the nurse call slave unit Visitors etc. equipped with a control device, a plurality of in-hospital cameras that are installed in appropriate positions such as hospital rooms and the like, and a slave camera that is installed at the entrance of the hospital and images visitors etc. A nurse call system having an interphone slave unit having a function of calling a nurse or the like and having a call function, and a monitor for displaying an NTSC signal image provided in the nurse call master unit. La outputs a digital video signal, the slave camera outputs a video signal as an NTSC signal, while the nurse call master unit or controller includes a video signal conversion unit for converting the digital video signal into an NTSC video signal. Both the captured image of the camera and the captured image of the slave camera can be displayed on the monitor.

According to this configuration, both an in-hospital camera that outputs a video signal as a digital signal and a captured image of a slave camera of an intercom slave that outputs as an NTSC signal can be displayed on a simple configuration NTSC monitor. Therefore, in-hospital camera wiring can be easily implemented like LAN wiring, and even a nurse call master unit used in a relatively small hospital can display both images on a monitor.
In addition, the intercom device and nurse call device can be integrated, the cost of the entire system can be reduced, and video can be displayed without using a digital device such as a personal computer. It is possible to configure a system that is difficult to stop.

The invention according to claim 2 is the invention according to claim 1, wherein the nurse call parent device includes a monitoring button for sequentially displaying the images of the in-hospital camera and the child camera on the monitor, and the nurse call parent device or the control device includes: It is characterized by having a monitoring order storage unit for storing the order of displaying captured images of the in-hospital camera and the slave camera, and a monitoring operation control unit for receiving the in-hospital camera and the entrance camera in a predetermined order in response to a monitoring button operation.
According to this configuration, it is possible to view a plurality of camera-captured images including a hospital entrance / exit from a nurse call parent device by a simple button operation. Therefore, it is possible to easily check the status of each place without troublesome operations of starting up individual cameras and displaying them on a monitor, and this can be utilized in the event of an emergency such as a suspicious person entering or an earthquake.

According to a third aspect of the present invention, in the first aspect of the present invention, the nurse call master unit includes a listening button that sequentially collects and collects the nurse call slave unit and the intercom slave unit at predetermined time intervals. The controller receives a listening order storage unit that stores the listening order of the nurse call slave unit and interphone slave unit, a camera arrangement storage unit that stores the relationship between the nurse call slave unit and the in-hospital camera, and a nurse call upon receiving a listening button operation. It has a listening control unit that sequentially activates at least the sound collection function of the call function of the slave unit and interphone slave unit, and operates the slave unit camera and the in-hospital camera according to the information in the camera arrangement storage unit. It is characterized by being able to listen in order while watching the video from the nurse call master unit.
According to this configuration, in-patients and entrance / exit situations can be heard sequentially with a simple button operation, and related images can also be confirmed. Therefore, it is convenient to check the situation quickly in case of an emergency such as an earthquake.

According to the present invention, both an in-hospital camera that outputs a video signal as a digital signal and a captured image of a slave camera of an intercom slave that outputs as an NTSC signal can be displayed on an NTSC monitor with a simple configuration. Therefore, in-hospital camera wiring can be easily implemented like LAN wiring, and even a nurse call master unit used in a relatively small hospital can display both images on a monitor.
In addition, the intercom device and nurse call device can be integrated, the cost of the entire system can be reduced, and video can be displayed without using a digital device such as a personal computer. It is possible to configure a system that is difficult to stop.

Further, the controller memory 22 constitutes a camera arrangement storage unit 22a that stores the relationship between the individual nurse call slave units 1, 1... And the in-hospital cameras 6, 6,.

  The nurse call system configured as described above operates as follows. However, an operation in which the nurse call cordless handset 1 is operated by a patient or the like to call a nurse, a corridor lamp 2 displays a call, and an operation in which the nurse responds from the nurse call master set 3 is the same as the conventional nurse call system. Since the operation is the same, the description is omitted, and here, the flow of the captured image of the hospital camera 6 and the flow of the captured image of the slave camera 33 of the interphone slave unit 5 will be mainly described.

  When the patient makes a call by pressing the call button 1b of the nurse call cordless handset 1, a call signal is transmitted to the controller 4 via the cordless handset transmission line L5, the corridor lamp 2, and the corridor lamp trunk line L2. Upon receiving the call signal, the controller CPU 23 transmits the call signal to the nurse call parent device 3 via the parent device transmission line L3, and controls the in-hospital camera 6 associated with the nurse call child device 1 that has been called. An imaging instruction signal is transmitted from the memory 22 to the associated hospital camera 6 via the communication line L5.

Upon receipt of the imaging instruction signal, the in-hospital camera 6 starts imaging, and an image including the caller's bed (patient) is captured. The captured image is transmitted as a digital signal, and is transmitted to the controller 4 via the communication line L5. The controller 4 that has received the video signal causes the video signal converter 21 to convert the transmitted video signal from a digital signal to an NTSC signal under the control of the controller CPU 23, and sends it to the nurse call parent device 3 via the transmission line L 3. To transmit.
Under the control of the master CPU 16, the nurse call master device 3 receives a call signal and reports a ringing tone, and displays the NTSC video signal received together on the monitor 11 via the video controller 12.

On the other hand, when the call button 30 of the intercom handset 5 is operated by a visitor or the like, a call signal is transmitted to the controller 4 via the transmission line L4. When receiving the call signal, the controller CPU 23 sends a call signal to the nurse call parent device 3 and sends an imaging instruction signal to the interphone slave device 5. The intercom handset 5 that has received the imaging instruction signal via the transmission line L4 activates the handset camera 33 to take an image of the visitor, and outputs the picked-up video as an NTSC signal.
When receiving the video signal from the intercom handset 5, the controller 4 transmits the video signal to the nurse call base unit 3 via the base unit transmission line L 3 without going through the video signal conversion unit 21.
Under the control of the master CPU 16, the nurse call master device 3 receives a call signal, sounds a ringing tone, and displays the received NTSC video signal on the monitor 11 via the video control unit 12. The ringing sound reported at this time is reported with a sound or melody different from the calling from the nurse call handset 1.

In this way, both the in-hospital camera that outputs a video signal as a digital signal and the captured image of the slave camera of the intercom slave that outputs as an NTSC signal can be displayed on an NTSC monitor with a simple configuration. Therefore, in-hospital camera wiring can be easily implemented like LAN wiring, and even a nurse call master unit used in a relatively small hospital can display both images on a monitor.
In addition, the intercom device and nurse call device can be integrated, the cost of the entire system can be reduced, and video can be displayed without using a digital device such as a personal computer. It is possible to configure a system that is difficult to stop.

Next, an operation when the monitoring button 14a of the nurse call parent device 3 is operated will be described. When the monitoring button 14a is operated, the captured images of the hospital camera 6 and the slave camera 33 are displayed on the monitor 11 in the preset order.
In response to the operation of the monitor button 14a, the master CPU 16 reads preset monitor order information from the monitor order storage unit 13a of the master memory 13, and sequentially sends camera activation signals to the controller 4 based on the information. . Receiving the camera activation signal, the controller CPU 23 sends an imaging instruction signal to the designated camera (in-hospital camera 6 or slave camera 33) to perform imaging. The imaged video signal is transmitted to the nurse call parent device 3 via the controller 4 and displayed on the monitor 11.
This camera imaging control is performed for all the cameras by switching the master CPU 16 sequentially, for example, every 10 seconds based on the monitoring order information, and the captured images are sequentially displayed on the monitor 11.

  In this way, the image captured by a plurality of cameras including the entrance of the hospital can be viewed from the nurse call master device with a simple button operation. Therefore, it is possible to easily check the status of each place without troublesome operations of starting up individual cameras and displaying them on a monitor, and this can be utilized in the event of an emergency such as a suspicious person entering or an earthquake.

  The operation when the listen button 14b of the nurse call parent device 3 is operated is as follows. When the listening button 14b is operated, the nurse call slave 1 and the interphone slave 5 microphones are activated in the preset order, and the in-hospital camera 6 or the slave camera 33 performs an imaging operation.

  In response to the operation of the listen button 13b, the master CPU 16 of the nurse call master device 3 reads the preset listening order information from the listening order storage unit 13b of the master memory 13, and based on the information, the nurse call slave device is read. 1 or a microphone activation signal for activating the microphone of the intercom handset 5 is sent to the controller 4. Receiving the microphone activation signal, the controller CPU 23 receives related camera information from the camera arrangement storage unit 22a of the controller memory 22 based on the child call information of the nurse call slave 1 or interphone slave 5 included in the microphone activation signal. And the microphone activation signal is transmitted to the nurse call slave unit 1 or the intercom slave unit 5 and the imaging instruction signal is transmitted to the related camera among the in-hospital camera 6 or the slave unit camera 33 to perform imaging.

The interphone handset 1 or the interphone handset 5 that has received the microphone activation signal activates the microphone, listens to surrounding sounds, and transmits the sounds to the nurse call base unit 3 via the controller 4. In addition, the imaged video signal of the activated camera is also transmitted to the intercom base unit 3 via the controller 4. The video signal from the in-hospital camera 6 is converted into an NTSC signal by the video signal conversion unit 21 and transmitted to the nurse call master unit 3.
Based on the listening order information, this parental control CPU 16 performs switching for every slave unit (nurse call slave unit 1 and intercom slave unit 5), for example, every 10 seconds. Are sequentially reported from the speaker of the communication unit 15 and the captured images of the camera related to the monitor 11 are sequentially displayed.

  In this way, in-patients and entrance / exit situations can be heard sequentially with a simple button operation, and related images can also be confirmed. Therefore, it is convenient to check the situation quickly in case of an emergency such as an earthquake.

In the above embodiment, the video signal converter 21 is provided in the controller 4, but it may be provided in the nurse call parent device 3. In addition, although the monitoring order storage unit 13a and the listening order storage unit 13b are provided in the nurse call master unit 3 and the camera arrangement storage unit 22a is provided in the controller 4, all the storage units may be provided in the controller 4. However, all the storage units may be provided in the nurse call parent device 3.
Furthermore, although only the microphones are sequentially activated by the operation of the listening button 14b, it is also possible to activate the speakers that form a pair of microphones. In this case, the nurse can make inquiries to the individual patients sequentially from the nurse call master unit 3, which is convenient.
