DESCRIPTION JP2001186266
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
nurse call apparatus, and more particularly to a nurse call apparatus in which a ringing volume
and a call volume are interlocked and changed according to the acoustic environment in a
hospital room such as night and daytime.
[0002]
2. Description of the Related Art Conventionally, as shown in FIG. 4, an example of this type of
nurse call apparatus is known.
[0003]
FIG. 4 is a block diagram showing a conventional nurse call apparatus.
In the figure, the conventional nurse call apparatus includes a nurse call master 6 installed at a
nurse station and a nurse call slave 8 installed at a bedside. It is connected to the nurse call slave
8 via the light trunk line 9 and the collective hallway light 7. Here, the nurse call master 6 has a
function of calling a patient in each room or calling in response to a call from a patient in each
room. In addition, the nurse call slave 8 has a function for a patient in each hospital room to call
the nurse call master 6 or to make a call in response to a call from the nurse call master 6.

[0004]
The nurse call master 6 includes a manual preset ringing volume adjuster 61 and a manual
preset transmission voice volume adjuster 62.
[0005]
The nurse call handset 8 includes a speaker 81, a manual reception volume control 82, a
microphone 83 and a call circuit 84. The call circuit 84 includes a collective hallway light 7, a
speaker 81, a reception volume control 82 and a microphone 83. It is connected to the.
[0006]
Next, the operation of the conventional nurse call apparatus configured as described above will
be described.
First, during loud daytime hours of ambient noise, the preset ringing volume adjuster 61 and the
preset transmission volume controller 62 of the nurse call master 6 are manually adjusted to
optimize the ringing volume and the call volume. Set to be
In addition, the patient manually adjusts the reception volume adjuster 82 of the nurse call slave
unit 8 to set the volume to an optimum volume for the patient himself and provide it in a normal
use state (see Japanese Patent Laid-Open No. 9-261354). .
[0007]
However, in the conventional nurse call apparatus, when the volume control is set on the
assumption of a large daytime period of ambient noise, the volume is too high in the nighttime
period where ambient noise is small. May disturb other patients' sleep. On the other hand, if the
volume adjustment is set on the assumption that the nighttime time zone where the ambient
noise is small is set, the volume may be too low in the daytime time zone where the ambient
noise is loud, which may cause a problem in the call.

The present invention has been made to solve such a problem, and it is an object of the present
invention to provide a nurse call apparatus capable of always making calls at an optimal volume
regardless of the daytime and nighttime hours.
[0009]
[Means for Solving the Problems] In order to achieve such an object, the nurse call apparatus of
the present invention is provided with a nurse call master unit and a plurality of nurse call slave
units connected to the nurse call master unit, A nurse call device that performs station selection /
calling / calling from a nurse call master unit to a nurse call slave unit, and calls / calls from a
nurse call slave unit to a nurse call master unit, wherein the nurse call master unit is The work
system setting switch for the night work, night work, etc., and the volume setting switch for
adjusting the call volume from the nurse call master to the nurse call slave according to the work
system set by the work system setting switch The volume control unit performs volume control
by inputting tuning data, work system data and volume adjustment data, and data for volume
adjustment is selected from the data and work system. When the data stored with the memory
and the data of the station selection of the nurse call slave are input to the volume control unit,
the control of the volume control unit refers to the data of the work system from the work
system setting switch at the time of the selection. It is characterized in that the electronic volume
is adjusted by the data of the tuning from the memory and the data of the volume adjustment
stored together with the data of the work system.
[0010]
According to the nurse call device of the present invention, the call volume and the call volume
are set to change in conjunction with the working system such as day shift, near night shift, night
shift etc. You can always talk at the optimal volume.

nurse call slave unit 3a is called to be in a call state.
[0019]
Next, press any one of the working system setting buttons 12a, 12b, 12c of the working system
such as day shift, night shift, etc., and switch any of the work system setting switches 41a, 41b,
41c interlocked with this. Then, the preset ringing volume adjuster 11c which increases the
volume or the preset transmission voice volume adjuster 11d which decreases the volume
operates either the volume setting switch 41d or the volume setting switch 41e linked thereto.
The switch is turned on to input volume adjustment data to the volume control unit 42.
Then, the electronic volume 44 is controlled by the volume adjustment data to adjust the call
volume. The data of this volume adjustment is stored in the memory 43 together with the tuning
data and the working system data. On the other hand, the data of the station selection of the
nurse call slave unit 3 is input to the volume control unit 42 as a station selection signal, and the
volume control unit 42 is controlled by the input of the station selection signal. As a result, the
data of the work system from the work system setting switch at the time of tuning is referred to,
and the data of the volume adjustment stored together with the data of the station selection and
the data of the work system is retrieved from the memory 43. The volume 44 is controlled and
adjusted to the set call volume.
[0020]
As described above, the volume adjustment setting is performed by selecting, calling, and calling
a nurse call slave device at the nurse call master device 1, and working system setting switch 41a
linked to the operation of the work system setting buttons 12a, 12b, and 12c. , 41b, 41c, and
then turn on the volume setting switch 41d or 41e linked to the operation of the preset call
volume adjuster 11c or the preset transmission voice volume adjuster 11d. Do.
[0021]
In the above embodiment, although the case where the volume control means is connected to the
nurse call master unit is described, the present invention is not limited to this, and the volume
control means may be built in the nurse call master unit .
[0022]
As apparent from the above description, according to the nurse call apparatus of the present
10-04-2019
