DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a nurse call system in a hospital.

``Prior art'' A conventional nurse call system consists of a call switch provided for each bed and a communication means provided corresponding to the call switch or commonly provided for multiple call switches. It consists of a device, a response device equipped with a call display means, a response switch, and a communication means, and a main device that is connected to each of the above devices by a communication line and controls calls, calls, etc. A response device is installed in the nurse's station in the hospital room.

FIG. 2 is a block diagram of a conventional nurse call system. A is the patient's room, B is the nurse's station, and the top is the call device, with a call switch 2 corresponding to each bed.
a to 2n, and communication means 3a to 3n each having a microphone, a speaker, etc. inside.

The communication means 3a to 3n are provided corresponding to the call switches 2a to 2n, respectively, but sometimes only one is provided in common.

The terminal is a response device, and is provided with a call display means 5 and a response switch 6. The call display means 5 is a call switch 2a-2.
The number corresponding to n indicates that the response switch 6 is connected to the communication means 3a to 3.
A number corresponding to n is provided. Reference numeral 7 indicates a telephone line 118 for controlling calls and telephone conversations, and reference numeral 9 indicates a handset.

Next, the operation will be explained.

When any of the call switches 2a to 2n is operated, the main device 7 detects this and sends a call signal to the corresponding call display means 5 on the answering device of the nurse station B, and the call display is displayed. It is done.

In response to this, when the response switch 6 is operated, a communication path is established with the calling device 1 that performed the calling operation under the control of the main device 7, and the handset 9 becomes capable of talking.

"Problems to be Solved by the Invention" In the conventional nurse call system described above, a nurse cannot respond to a call unless she is present at nurse station B. Therefore, the number of nurses at night is limited. When the number of nurses decreases, there is a problem that nurses may not always be in the room and may not be able to respond to calls or may be delayed.

Moreover, even if there was a nurse near the hospital room A where the call was made, it would be unreasonable for the nurse to return to the nurse station B, confirm the caller, and then go back to the hospital room A.

In view of the above-mentioned points, the present invention is intended to provide conventional functions and also to allow calls to be answered and telephone conversations to be made at any location apart from the nursing station B.

Therefore, the present invention provides a means for solving the problem, from a call switch provided correspondingly to each bet, and a call means provided correspondingly to the call switch or commonly provided to a plurality of call switches. an answering device including a calling display means, an answering switch, and a talking means; a cordless parent device including a wireless transmitter/receiver; a transceiver for performing wireless communication with the cordless parent device; It consists of a main device that is connected to each device by a communication line and controls calls, calls, etc. When the call switch is operated, the main device simultaneously calls the answering device and the cordless master device and responds to the call first. A communication path is formed between the device that received the response operation and the above-mentioned calling device.

"Operation" When there is a calling operation from the calling device, both the answering device and the cordless parent device are called, and a response can be made from either the answering device or the transceiver.

A power source 38 is a power separation filter for supplying power to the response wave Ll=L and the cordless housing 220, and both can be configured by, for example, a circuit included in a well-known button telephone device. Reference numeral 18 denotes a communication line consisting of the data lines 37a to 37n and speech lines 39a to 39n described above.

Since the configuration of the calling bag 1 and the answering device AE is the same as that of the conventional structure, illustration thereof is omitted.

The cordless master device 20 is provided with a wireless transmission/reception circuit, which will be described later, but basically has the same configuration as the response device n. 40 is a power separation filter, and data line 3
separating the power from the power source 36 provided via 7a;
It is supplied to the constant voltage circuit 41. The output voltage of the constant voltage circuit 41 is applied to each part of the cordless main device 20.

42 is a data transmission/reception circuit, 43 is a control circuit, 44 is a wireless transmission/reception circuit, 45 is a 2-wire to 4-wire conversion circuit, and 46 is an antenna. The wireless transmitting/receiving circuit 44 is under the control of the control circuit 43 and is configured to transmit and receive transmission signals and control signals by forming a wireless line with the transceiver 21 . In the transceiver 21, 47 is an antenna, 48 is a wireless transmission/reception circuit, 49 is a control circuit, 50.51 is an amplifier,
52 is a receiver, 53 is a transmitter, 54 is a response switch, 5
5 is a display, and 56 is a battery. The wireless transmitter/receiver circuit 48 is 1111! of the control circuit 49! The above wireless transmitter/receiver circuit 4 under

Now, for example, when operating the call switch 12a to call up the answering device from the top of the calling device, the calling device 13a
The information is received by the data transmitting/receiving circuit 35 via the data line 37n from the control circuit therein, and is given to the control circuit 34. This causes the control circuit 34 to control the data transmission/reception circuit 3.
5 to transmit call data onto the caller.

The calling data is applied to the calling device from the data line 37b, and the calling device U outputs a ringing tone. In response to this, the control circuit 34 controls the extension circuit 33n to which the calling device U is connected and the extension circuit 33b to which the answering device top is connected to the operating state, and also controls the call path switch 32 to connect the extension circuit 33n to which the calling device U is connected. The operation of 0 or more in which the communication path between the circuits 33b and 33n is closed and communication is possible between the top of the calling device and the top of the answering device is the same as in the prior art, but in the present invention, the above-mentioned calling device When the call information for the response device U is given from m, the control circuit 34, in addition to the above-described operations, controls the data transmitting/receiving circuit 35 so that the data transmitting/receiving circuit 35 transmits the calling data for the cordless receiver w20. Therefore, the call data is given to the data transmitting/receiving circuit 42 of the cordless parent device 20 via the data line 37a. Accordingly, the control circuit 43 controls the wireless transmitting/receiving circuit 44 to establish a wireless channel with the transceiver 21. That is, the antenna 46
emit a predetermined radio wave. When the tl radio wave is received by the radio transmitting/receiving circuit 48 via the antenna 47 and a radio channel is formed, the control circuit 43 sends a paging signal to the radio channel, which is transmitted to the control circuit 49 of the transceiver 21.
, the control circuit 49 drives the display 55 to display a call.

When the response switch 54 is operated in order to respond to a corpse call, the response information is given to the control circuit 43 via the wireless channel under the control of the control circuit 49, and the 2-wire-411 exchange is performed under the control of the control circuit 43. A circuit 45 is connected to the wireless transmitting/receiving circuit 44 . The control circuit 43 also controls the data transmitting/receiving circuit 42 to provide the response information as data to the control circuit 34 via the data line 37a and the data transmitting/receiving circuit 35.

The control circuit 34 activates the extension circuit 33a based on the response information and controls the communication path switch 32.
Connect extension circuits 33a and 33n. Thereby, the transceiver 21 can communicate with the calling device U using the receiver 52 and the transmitter 53.

The control circuit 34 disables the answering device by sending the first call data, and if there is response information from either of the transceivers 21, it releases the other call data and does not close the other communication path.

Note that whether or not to send out the calling data for the cordless parent device at the same time when sending out the calling data for stopping the answering device is determined by setting means for the control circuit 34, for example, by providing a switch in the main device 17 and turning it on or off. It can be configured such that one of the control programs is selected by turning OFF.

Therefore, depending on the number of nurses mentioned above, it is possible to select whether to use the transceiver 21 or not, and if it is not used, the operation will be the same as in the past, and no inconvenience will occur.

"Effects of the Invention" As explained above, according to the present invention, when the answering device is called, the transceiver is also called at the same time, so that when the nurse leaves the nursing station, the nurse can carry the transceiver with her and respond to the call. Answers can be made without returning to the nurse's station, and since the cordless master unit is configured to be connected to the main unit's extension circuit by wire, it is possible to make calls with the transceiver without making major changes to the conventional main unit. becomes.
