Next, the operation of the conventional nurse call intercom device configured as described above will be described.

First, the nurse call intercom device will be explained.

The patient makes a call to the nurse station 10 by pressing the call handle button 33. The nurse call intercom base unit 11 of the nurse station 10 receives this and sounds a ringing tone. When a nurse answers a call using the nurse call interphone main unit 11, the patient can hear the patient's voice from the loudspeaker of the hospital room slave unit Ia32 of the nurse call interphone, while the patient's voice can also be heard from the patient room slave unit Ia32 of the nurse call interphone. 32 loudspeaker microphones to the nurse, thus allowing the patient to communicate with the nurse without using hands. When the nurse ends the call using the nurse call intercom base unit 11, this call ends.

In addition, the nurse selects a channel on the patient room handset 32 using a channel selection button (not shown) provided on the nurse call intercom base unit 11, and thereby sounds a call warning tone to the patient room handset 32. and then immediately enters into a communication state with the patient room slave unit 32. In this way, again, the patient can communicate with the nurse without any hassle. The call ends when the nurse ends the call using the nurse call intercom base unit 11.

Furthermore, the nurse uses the nurse call intercom base unit 11 to select any plurality of patient room slave units 32. Alternatively, channel selection broadcasting or all-station broadcasting can be performed to the patient room slave units 32 of all the patient rooms 30. In this case, by operating the broadcast on the nurse call intercom base unit 11, the nurse's voice will be heard as a broadcast on the patient room slave unit 32 following the broadcast warning sound, but the sound reinforcement microphone of the patient room slave unit 32 will be heard as a broadcast. Since it is not turned on, the patient's voice is not sent to the nurse call intercom base unit 11.

Next, the PBX terminal device will be explained. Patients can call (
When making a call to an outside line or an extension, pick up the handset of the telephone 35, operate the dial button of the telephone 35 to make a call (outside line) or an extension, and end the call by putting down the handset.

In addition, when an incoming call is received from an outside line, a ring tone sounds from the telephone set 35, and the patient picks up the handset to begin the call. Put down the handset and end the call.

However, since the conventional nurse call intercom device and PBX terminal device in a patient's room are configured as described above, ■ the patient's room handset 32 and telephone 35 must be installed separately at the bedside of the patient. Also, if the hospital room handset 32 is selected from the nurse call intercom main unit 11 while the patient is making an external or internal call using the telephone 35, the patient room handset 32 will immediately amplify the sound. Since the patient is in a talking state, what the patient is saying on the outside line or extension line can be eavesdropped on by the nurse call intercom base unit 11, making it impossible to ensure the patient's privacy.

Similarly, while the patient is talking to the nurse call intercom base unit 11 using the patient room handset 32, an outside call is received on the telephone 35.
Even if the patient picks up the handset of the telephone 35 to make an outside call, the contents of the call can be intercepted by the nurse call intercom base unit 11.

There were drawbacks such as the inability to ensure patient privacy.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a nurse call terminal device with a telephone function in which a patient room handset and a telephone are integrated into the same housing.
