It should be noted that there is also a hand slave device 15 of a type without the push button switch 16.

In the present invention, as shown in FIG. 1, the nurse center 3 and a nurse moving in the ward 2 use a wireless system so that they can respond to each other with a telephone 18 of a PHS terminal carried by the nurse or doctor. When a call is received from the patient, the nurse center 3 must be able to wirelessly contact the telephone 18 of the PHS terminal via the base station 6 if necessary, and ensure the call from the patient side. Equipment that must be used, that is, the toilet push button switch 14, the hand button 15

The corridor lamp 11 and the like are connected to the nurse center 3 by wire, so that communication can be reliably established by wire. As described above, the hand slave unit 15 and the patient-specific corridor lamp device 12 can be contacted by radio, so that every effort is taken.

A feature of this embodiment is that the power line 10 for transmitting power from the nurse center 3 to the above-mentioned devices is shared as a power supply line and a transmission line for a call signal, thereby reducing the number of lines. .

That is, when the patient in the sickroom 4 presses, for example, the push button switch 16, the calling signal goes to the patient-specific corridor light device 12 and the corridor light 11 via the wiring 13.

The corridor light 11 is turned on by this signal and the power supplied from the display power supply 8 of the nurse center 3 via the power supply line 10, so that the nurse can easily know where he is calling. I have.

Further, the call signal is sent to the display power supply device 8 via the power supply line 10 to turn on the display lamp 9a.

As described above, the display power supply 8 is connected to the wiring 13,
When the push button is pressed through the patient-specific corridor light device 12 and the power line 10, the fact that the push button is pressed is displayed, and the power of the nurse call system is supplied to the hospital room 4 and the like via the power line 10. The display power supply device 8 will be described below.

FIG. 8 is a block diagram showing an example of the display power supply device. The display power supply device 8 includes a power supply unit 19 that supplies power to each device via the power supply line 10, a current measurement device 20 that detects a call signal by a push button switch operation of a push button from the hospital room 4, A CPU 21 for determining whether the button is a button or controlling another device, a display unit 9 for lighting a specific one corresponding to a push button pressed from among the plurality of indicator lights 9a by a signal from the CPU 21, and the like. I have.

In operation, the current consumed through the power supply line 10 can be measured by the current measuring device 20. Also, from the measured current value, CP
U21 determines which bed in the hospital room 4 is the push button operated by the patient.

As shown in FIG. 3, the patient-specific corridor lamp device 12 is connected to the power line 10 when the push button switch is pressed.
There is an indicator light 12b that is turned on through the
b blinks by the reset button. The patient-specific corridor lamp device 12 has a calling circuit described below.

FIG. 9 is a schematic diagram of the calling circuit. This calling circuit corresponds to the case where there are four beds in the sickroom 4 and one toilet, and a plurality of latches 79 (circuits for registering information) are provided correspondingly. Each latch 79 has set and reset input terminals S and R, and the set input terminal S is connected to a push button switch of each device connected to the wiring 13 via the wirings 80 to 84, respectively. I have.

Each latch 79 is connected to the push button switch 14
16 is pressed, the corresponding latch 79 is set, and once set, functions as a switch for connecting the cathodes of the light emitting diodes 69, 75-78 connected to the set latch 79 to ground. I do. Each of the latches 79 is reset when the reset button switch 90 is pressed, and once reset, the light emitting diodes 69 and 7 connected to the reset latch 79 are reset.
The cathodes 5 to 78 are open ends.

The anodes of the light emitting diodes 69, 75 to 78 are provided with constant current means 70 to 70 for supplying a predetermined current respectively.
74 are connected. These constant current means 70 to 74
Have different current values.

For example, the constant current means 71 is 50.00 m
A, constant current means 72 is 50.01 mA, constant current means 73
Is 50.02 mA, the constant current means 74 is 50.04 mA,
The one for the toilet push button switch 14 and the one for other hospital rooms have constant current means (for example, 5
0.10 mA, 50.11 mA, 50.12 mA, 5
0.14 mA, next room 50.20 mA, 5
Each digit excluding the tens digit is numerically composed of 0, 1, 2, 4 such as 0.21 mA, 50.22 mA, 50.24 mA, and even if current flows simultaneously by these constant current means, any constant It is possible to determine whether the current has been consumed via the current means), and each constant current means is set to have a unique current value for one of the push button switches. .

These constant current means are connected to the power supply line 10 via the power supply line 70 '. Corridor light 11 is power line 70 '
Is turned on through the detection means 68 when the current has flowed through the device.

Next, how the display power supply device 8 can determine which of the push button switches 14 to 16 have been pressed will be described with reference to an example in which there are four beds in the hospital room 4. I do.

When any one of the push button switches 14 to 16 is pressed, a signal is sent to the patient-specific corridor lamp device 12 through the wiring 13 and further through the wirings 80 to 84, and the signal is sent to the set input terminal S of the specific latch 79. A signal is input. As a result, the specific latch 79 is set, and the corresponding specific one of the light emitting diodes 69, 75 to 78 corresponding to the indicator light 12b of FIG. 3 connected to the specific latch 79 corresponds to the patient name. Light is emitted.

Here, for example, assuming that the light emitting diode 76 emits light, the current value 50.0
1 mA is consumed. This consumed current value flows through the power supply line 10 and is supplied to the current measuring device 20 of the display power supply device 8.
The CPU 21 in the display power supply 8 determines from which bed the push button has been pressed, and the determined bed lights up on the corresponding indicator light 9a of the display power supply 8 from the measured value. Is displayed.

In this embodiment, a plurality of push button switches 14
It is possible to cope with a case where the user presses .about.16. The push button switches 14 to 1 for a plurality of beds will be described below.
The case where 6 is pressed will be described. For example, assume that there are 60 places where the push button switches are installed.

In this case, when the current value of the constant current means is set as in the above example, the value of the constant current is 50.00 mA, 5
0.01 mA, 50.02 mA, 50.04 mA, 5
0.10 mA, 50.11 mA, 50.12 mA, 5
0.14 mA, 50.20 mA, 50.21 mA, 5
0.22 mA, 50.24 mA or more, and the maximum value is 54.
24 mA. Therefore, by dividing the current value (mA) consumed through the power supply line 10 by 50, the number of pressed push-button switches can be determined. It can be determined whether or not is pressed.

With the above configuration, it is possible to determine which push button switch has been pressed based on the current consumption value via the power supply line 10. Therefore, it is necessary to provide a separate signal line only for this determination. Because there is no, wiring work can be largely omitted, and even when the information transmission by wireless is insufficient due to bad radio wave condition etc., it is possible to know where the bed was called from A nurse call system can be provided.

FIG. 10 is a schematic diagram showing another embodiment of the calling circuit.

Reference numeral 85 in FIG. 10 denotes a protection resistor for current control. Reference numeral 100 denotes an oscillation unit that outputs a reference frequency.

Reference numerals 95 to 98 denote latches when there are four beds. The latches have the same function as the latch 79, receive the reference frequency output from the oscillating means 100, and adjust the frequency to a freely set positive. This is a lighting latch capable of dividing the frequency by an integer, and lighting the light emitting diodes 69, 75 to 78 at the divided frequency.
That is, when any one of the push button switches 14 to 16 is pressed, the corresponding light emitting diode 69, 75 to 78 is turned on by the lighting latches 95 to 98 at the frequency set to its unique value. I have.

In this case, the display power supply 8
Is provided with a frequency measuring device capable of measuring the frequency at which the current consumption changes, and is provided with a CPU capable of judging which room's push button switches 14 to 16 have been pressed when the value of the measured frequency is input. I have. Further, the frequency measuring device can measure a plurality of frequencies separately. Therefore, even if the push button switches 14 to 1
Even if the button 6 is pressed in several places, the frequency measuring device can discriminate and determine the frequency, so that it is possible to know where the push button switches 14 to 16 are pressed.

That is, in this example, the frequency at which the current consumption changes via the power supply line 10 is measured by a frequency measuring device provided in the display power supply 8 in place of the current measuring device, and the measured frequency is displayed. CP provided in power supply device 8
U21, the CPU 21 can determine which push button switches 14 to 16 have been pressed, can eliminate another signal line, and even when the wireless information transmission is insufficient, It is possible to provide a reliable nurse call system in which it is possible to know whether or not a call has been made from the push button switch by displaying via the CPU 21 provided in the display power supply device 8.

As described above, in the present invention, the power supply line 10 is used not only for supplying power but also as an information transmission line for clarifying the place of information transmission, so that the number of wirings can be reduced.

Although the above embodiment does not exemplify a nurse call system having a digital line, the present invention can be applied to a nurse call system including a digital line.
That is, the power supply line 10 is used for power supply, and a digital line is separately drawn from the nurse center 3 to the patient-specific corridor light device 12 on the hospital room 4 side, and digital signals corresponding to on and off from the above-described push button switches are transmitted. It may be generated and transmitted to the nurse center 3 to operate the display unit 9. In this case, it takes time and effort to draw a digital line as compared with the above-described embodiment. However, since a digital circuit can transmit a larger amount of information than an analog type, each line is connected to a nurse center from each device as before. Compared to wiring to the third side, the wiring work can be greatly simplified.

[0048]

According to the present invention, a nurse call system is configured by wireless and wired, and a plurality of devices for calling from a patient provided in a nurse center and a patient in a hospital room are connected by a power supply line. Since the power supply line is used to supply power to equipment and to transmit call signals, wiring work can be greatly reduced, so it is highly economical and can call a nurse center reliably in an emergency, and a highly reliable nurse A call system can be obtained.
