Description

  The present invention relates to a nurse call system used in a hospital or a nursing facility, and in particular, in a nurse call slave installed at a patient's bedside, a general call from a patient and a staff call from a medical staff such as a nurse. This is related to a nurse call system that can respond without a staff call button.

Some nurse call cordless handsets have only a general call button dedicated to the patient. However, the nurse may need to support the medical staff during nursing treatment at the patient's bedside. It is convenient to have a dedicated staff call button.

Patent Literature 1 describes this type of nurse call device.
In this way, if there are two types of buttons, the general call button for patients and the staff call button for medical staff, in one nurse call cordless handset, the patient is inadvertently ignorant or ignorant. The possibility of operating the call button for staff is inevitable.
Generally, in order to reduce such an erroneous operation, the staff call button is conventionally protected by a protective cover.

Non-patent document 1 is introduced as an example with a cover.
This is the staff call push button in the drawing of the hand type slave unit connection plate (W1-A) shown on page 360 of Non-Patent Document 1.
If you look at the standard column for the button, you can see that it is a staff-only call push button, with a non-locking cover (with “staff-only” characters).

The staff call button is equipped with a cover as standard in a known example, but patients, especially children and some other patients, accidentally or mischiefly open the button cover and open the staff call button. There are many troubles to push, and there are many places where it is difficult to respond.

As described above, when there are two types of call buttons for the patient and the call button for staff, there is a problem that the user may be unsure to select which one to press or wrongly press the other unintended call button. Arise. An object of the present invention is to prevent such a problem.

In the present invention, a nurse call cordless handset is provided with a general call button dedicated to a patient and a tag reader for reading an identification signal transmitted from a radio tag attached to the arm of a hospital staff such as a nurse, A general call signal is transmitted by operating a general call button, and a staff call signal is transmitted by bringing the wireless tag close to a tag reader.

According to the present invention, since there is only one type of call button, there is no doubt as to which one should be used as when there are two types of call buttons. In addition, it is possible to solve the problem that a person other than the medical staff calls the staff by mischief.

Embodiments according to the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the entire configuration of the nurse call system according to the present invention is comprised of a nurse call master unit 1, a nurse call control unit 2, and an individual corridor lamp installed at the entrance of each hospital room. 3. The nurse call slave unit 4 installed on the bedside of the patient is connected to each other by a wired connection, and the nurse call controller 2 is further connected via a cordless main unit 5. Wireless base station 6 is connected. 7 is a portable terminal that can wirelessly transmit to and receive from the wireless base station 6, and is generally carried by a medical staff such as a nurse.

Next, the whole nurse call operation will be described with reference to FIG.
The nurse call handset 4 is normally used by being incorporated in a bedside wall or console of a patient. In the figure, 8 is a speaker for receiving, 9 is a microphone for transmitting, 10 is a general call button used when a patient calls a nurse or the like, and 11 is a tag reader. Here, the tuck reader may be a wireless type, and may be an optical type or a radio type.

By the way, when the general call button 10 is pressed, a call signal is transmitted through the corridor lamp 3 and the nurse call controller 2 to the nurse call master unit 1 and the cordless main device 5, the wireless base station 6, a portable terminal carried by a nurse, etc. 7 is sent.

As a result, a representative lamp (not shown) and an individual indicator lamp (not shown) of the individual corridor lamp 3 are turned on or blinking, and a ringing tone is generated from the nurse call master unit 1 and the portable terminal 7, and the calling state is changed. It is displayed electronically, that is, on an LED or a liquid crystal screen.

In this calling state, when a response operation is performed on either the nurse call parent device 1 or the portable terminal 7, the communication path between the nurse call parent device 1 or the portable terminal 7 and the nurse call child device 4 is closed, I can talk. As for the individual corridor lamp 3, the display of the representative lamp and the individual indicator lamp disappears when the call starts.

The nurse call handset 4 includes the tag reader 11 as described above. When an identification tag (to be described later) is brought close to the tag reader 11, this is detected, and the nurse call handset 4 receives a staff call signal. Occurs.

The staff call signal is sent to the individual corridor lamp 3, the nurse call control unit 2, the nurse call master unit 1, the cordless main unit 5, the radio base station 6, and the portable terminal 7 through the same route as the general call signal described above. A staff calling sound is emitted from the call base unit 1 and the portable terminal 7, and the staff calling state is displayed. The staff call tone and the staff call status display are sounds and displays that can be distinguished from the general call described above.

FIG. 2 is a block diagram of portions of the nurse call slave unit 4 and the individual corridor lamp 3 in one embodiment of the present invention, and the call operation of the nurse call system will be described with this block diagram.
In the figure, reference numeral 12 denotes a wireless tag that can be used by being worn on the wrist of a medical staff such as a nurse, and can be handled by a bar code label, an IC tag, an RFID chip, or the like. Reference numeral 11 denotes a tag reader that can detect the wireless tag 12 and read the tag data by bringing the wireless tag 12 close to the wireless tag 12, and is connected to the call control unit 13.

The call control unit 13 is connected to a general call button 10 and a call confirmation lamp (general call confirmation lamp 14a and staff call confirmation lamp 14b). In this embodiment, the call confirmation lamp 14 is composed of a two-color LED, and lights up in blue when a general call is made and in red when a staff call is made.
In addition, as the call confirmation lamp 14, two independent LEDs can be used.

A call control unit 15 is connected to the speaker 8 and the microphone 9 described above.
The call control unit 15 and the call control unit 13 are respectively connected to the line interface 17 of the individual corridor lamp 3 via the input / output interface 16.

The control unit 18 of the individual corridor lamp 3 is connected to the line interface 17, the representative lamp 19, the individual indicator lamp 20, and the communication interface 21, and is also connected to the nurse call controller 2 via the communication interface 21.

Next, the calling operation will be described with reference to FIG.
The call control unit 13 of the nurse call slave device 4 converts the identification signal of the wireless tag 12 read by the tag reader 11 into a stuff call signal. On the other hand, when a general call button pressing signal is received, it is converted into a general call signal.

Next, the general call signal and the staff call signal are each converted into a predetermined voltage in the call control unit, and then sent to the line interface 17 of the individual corridor lamp 3 via the input / output interface 16.

At the same time, the call control unit 13 turns on the call confirmation lamp 14 corresponding to the type of the received call signal. That is, in the case of a staff call, the red staff call confirmation lamp 14b is turned on, and in the case of a general call, the blue general call confirmation lamp 14a is turned on.

When the individual corridor lamp 3 receives the general call signal or the staff call signal from the nurse call slave unit 4 via the line interface 17, the individual corridor lamp 3 controls the representative lamp 19 and the called nurse call slave unit 4 under the control of the control unit 18. The corresponding individual indicator 20 is turned on or blinked.

At the same time, a call signal is transmitted to the nurse call controller 2 via the communication interface 21. The information included in the call signal includes a call type signal for distinguishing a general call from a staff call together with an identification number of the calling nurse call slave.

The nurse call controller 2 receives and decodes such a call signal, and controls the nurse call master unit 1 and the cordless main unit 5 by a predetermined program in accordance with the result, thereby causing the call operation to be executed.

In the embodiment, it is only necessary to distinguish whether or not the wireless tag is a staff member, and each medical staff member can use a common wireless tag.

Of course, if a wireless tag having an identification code for each medical staff is used, a nurse call system for displaying a staff caller on the nurse call parent device or mobile terminal can be configured by those skilled in the art. It can be easily made based on the invention.

The block diagram which shows one Example of the nurse call system by this invention. 1 is a block diagram of an individual corridor lamp and a nurse call slave unit in one embodiment of the present invention.
