DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nurse call apparatus, and when a sound volume level in a room input from a ceiling microphone is high, a communication path between the nurse call master unit and the room is formed, and the state of the room is confirmed. Related to a nurse call device that can be used.

[0002]

2. Description of the Related Art Conventionally, there is a nurse call apparatus of this type shown in FIG.

This nurse call device includes a ceiling speaker 1b, a call button 2b, and a ceiling microphone 3b provided on each bed in a hospital room, an adapter 4b installed in each hospital room for detecting the call button 2b, and an adapter 4b. It comprises a controller 5b for receiving a call, and a nurse call master unit 6b controlled by the controller 5b and notified of a call.

The adapter 4b includes a call detection circuit 42b for detecting a call by pressing the call button 2b, and a ceiling microphone amplifier 44b for amplifying a voice signal from the ceiling microphone 3b.
And a ceiling speaker amplifier 41b for amplifying an audio signal from the controller 5b, a ceiling microphone amplifier 44b when a call is detected by the call detection circuit 42b, and a CPU 43b for driving the ceiling speaker amplifier 41b.

The nurse call base unit 6b includes a microphone amplifier 67b for amplifying an audio signal from the microphone 66b and a controller 5b.
A speaker amplifier 62b for amplifying an audio signal from the user, a call display section 63b that flashes when there is a call, a channel selection button 64b that is pressed when the user wants to talk with the sickroom, a call end button 68b and a channel selection button 64b that are pressed when the call ends. When selecting a channel, a CP that drives the microphone amplifier 67b and the speaker amplifier 62b
U65b.

When the caregiver wants to confirm the condition of the patient in the sickroom, he / she presses the sickroom channel selection button 64b of the nurse call master device 6b so that the nurse call master device 6b can talk to the sickroom. Is displayed, a call display section 63b indicating the location of the hospital room to be called is displayed, and the speaker amplifier 62b and the microphone amplifier 67b are driven.
The hospital room selection data is sent to the controller 5b.

[0007] The controller 5b receives the sickroom selection data from the nurse call master 6b and sends the information to the adapter 4b.

[0008] The adapter 4b receives data from the controller 5b by the CPU 43b and drives the speaker amplifier 41b and the microphone amplifier 44b.

As a result, the communication path between the nurse call base unit 6b and the sickroom is opened, and the voice in the sickroom is heard from the speaker 61b via the microphone 3b, the microphone amplifier 44b, the controller 5b, and the speaker amplifier 62b. The state in the hospital room and the state of the patient can be confirmed by voice from the master unit 6b. After confirmation, pressing the end button 68b of the nurse call master device 6b ends the call.

[0010]

In such a nurse call system, when a caregiver wants to confirm the condition of a patient in a hospital room, he or she presses the hospital room selection button 64b of the nurse call master unit 6b, and the nurse call master unit. 6b, controller 5b,
A signal is sent to the adapter 4b to enable communication between the nurse call base unit 6b and the sickroom, but the data is not sent to the controller 5b and the adapter 4b unless the sickroom selection button 64b is pressed. A communication path is not opened between the master unit 6b and the sickroom, and the nurse call master unit 6b cannot hear the sound in the sickroom. For this reason, when the caregiver is away from the nurse call master device 6b, the room selection button 64b is selected.
Cannot be pressed, a mentally unstable patient is in an abnormal state, and there is a problem that even if the patient is making noise in the room, he cannot hear the sound in the room.

The present invention has been made in order to eliminate the above-mentioned difficulties of the nurse call apparatus. When the volume level of a room input from a ceiling microphone is high, the nurse call unit 6b and the room are not connected. It is an object of the present invention to provide a nurse call device in which a communication path is formed and a state in a hospital room can be confirmed by the nurse call master device 6b.

[0012]

In order to achieve the above object, a nurse call device according to the present invention detects a ceiling speaker, a ceiling microphone, a call button, and a call of a call button provided on each bed in a hospital room. A nurse call device including an adapter for notifying a nurse call base unit of a call via a controller, wherein the adapter includes a volume level determination circuit that determines a volume level in a hospital room input from a ceiling microphone, When the volume level determined by the volume level determination circuit is higher than a predetermined level during normal conversation, a CP that performs control to form a communication path between the nurse call master unit and the sickroom.
U.

According to this nurse call device, when the volume level of the room input from the ceiling microphone is high, a communication path between the nurse call base unit and the room is formed, and the nurse call base unit can hear the sound in the room. , The condition in the room can be confirmed.

[0014]
