To do. On the other hand, an object of the present invention is to provide a nurse call system that allows a nurse or the like to be called and talked using a bedside nurse call cordless handset when on a bed in a hospital room.

The present invention provides a portable terminal for staff and a portable terminal for patients as portable terminals, and sets and registers the portable terminal for patients so as to correspond to a specific nurse call cordless handset line. By performing a call operation on the child device or the portable terminal for a patient, the nurse call parent device and the portable terminal for staff can be called and a call can be made to the other party who has responded first.

Further, the present invention calls a patient portable terminal and a nurse call slave corresponding to the call line by selecting and calling a specific nurse call slave line from the nurse call parent device or the portable terminal for staff. It is characterized in that a call can be made with the person who responded first.

Further, according to the present invention, by selecting and calling a specific nurse call slave unit line from the nurse call parent device or the staff mobile terminal, first, the designated patient mobile terminal is called for a certain period of time, and there is no response within the certain time. In some cases, the call of the patient portable terminal is restored, and the voice call is made possible by automatically connecting to the nurse call slave unit.

According to the present invention, the bedside nurse call child device and the portable terminal for a patient can be used properly according to the patient's situation, so that the patient calls the medical staff and asks for support when necessary inside or outside the hospital room. be able to.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a block diagram of a nurse call system showing an embodiment of the present invention.
Reference numeral 1 denotes a nurse call parent device installed in a nurse center of a hospital or a management center of a welfare facility, and includes a call function using a handset, a liquid crystal monitor with a touch panel, and a charging box for a portable terminal. Reference numeral 2 denotes a corridor lamp connected to the nurse call master unit 1 and is generally installed on the corridor side of each hospital room entrance. Reference numeral 3 denotes a nurse call slave connected to a corridor lamp, and includes a call function using a speaker and a microphone, a call button 3a, and a response button 3b.

A plurality of radio base stations 5 are further connected to the nurse call parent device 1 via the main device 4. There are two types of portable terminals that can communicate with the wireless base station 5 wirelessly. That is, a staff portable terminal carried by a medical staff such as a nurse and a patient portable terminal 7 carried by a specific patient as necessary are provided. In the example shown in the figure, the patient mobile terminal 7 is simple in that it has only the minimum necessary operation buttons such as a call button, a response button, and a power button, thereby limiting the application for nurse calls and preventing erroneous operations. It can be done. As the patient portable terminal 6, as with the staff portable terminal 7, a normal PHS type that can be selected with a numeric keypad can be used.

Next, the overall schematic operation will be described with reference to FIG. First, when the call button 3 a of the nurse call slave unit 3 is pressed, a call signal is sent to the nurse call master unit 1 via the corridor lamp 2. At this time, the representative lamp blinks in the corridor lamp 2, and the call from the patient is notified to the staff or the like moving in the hospital room corridor. At the same time, the nurse call master unit 1 sounds a ringing tone to notify a nurse or the like in the management center of the call from the patient. At this time, the name of the calling patient, nursing information, etc. are highlighted or displayed in a pop-up on the screen of the nurse call master unit 1.

At the same time, the call signal from the nurse call slave unit 3 is sent from the nurse call master unit 1 to the radio base station 5 via the main unit 4 and calls the specific portable terminal 6 for staff designated by the transmission radio wave.

In this state, if a response operation is performed on either the nurse call master unit 1 or the staff portable terminal 6, the ringing tone stops, and the one that answers first and the nurse call slave unit 3 mutually A call can be made, and the ringing sound of the nurse call parent device 1 or the staff portable terminal 6 on the unanswered side stops.

In FIG. 1, the patient portable terminal 7 is a portable terminal registered in advance for a specific patient in the nurse call parent device 1 as described later. This patient portable terminal 7 is carried when going to the toilet or when the patient leaves the bed for the purpose of examination, so that the nurse can use the portable terminal 7 anywhere in the ward. The call parent device 1 and the staff portable terminal 6 can be called.

In addition, even if it is the holder of the portable terminal 7 for patients, when it is on the bed, the nurse call main unit 1 and the portable terminal 6 for staff can be called using the nurse call cordless handset 3 to make a call. It is not necessary to dare to use the patient portable terminal 7.

FIG. 2 is a block diagram of a nurse call system in one embodiment of the present invention.
The main device 4 is a network switching device similar to a digital switching device, and includes an NC interface 8, a speech path switch 9, a wireless interface 10, a central processing unit 11, a storage device 12, and a data bus 13.

A nurse call parent device 1 connected to the NC interface 8 via an input / output interface 14 is a computer-driven nurse call parent device, and includes a CPU 15 for controlling the overall operation,
Storage means 16 composed of RAM, ROM, input / output means 17 including various operation switches, a liquid crystal monitor with a touch panel, etc., call means 18 including a handset and a call control means, a sound source control of a ringing tone, a speaker, etc. The call means 19 and the input / output interface 20 connected to the corridor lamp 2 are provided.

The storage means 16 stores various data in addition to program data for controlling the overall operation. That is, as will be described later, management data as an event file, patient data as a master file, line data, terminal allocation data, team organization data, patient handling data, and the like are stored.

The wireless interface 10 of the main apparatus 4 is wirelessly connected to the staff portable terminal 6 and the patient portable terminal 7 via a plurality of wireless base stations 5. As both the portable terminals 6 and 7, PHS which is considered to be difficult to cause radio wave interference to medical equipment is usually used.

The central processing unit 11 that controls the overall operation of the main device 4 includes a CPU and performs overall control of the main device 4 according to an operation program stored in advance in the storage device 12. The central processing unit 11 is connected to the speech path switch 9 and the storage device 12 via the data bus 13. The storage device 12 stores and stores various tables such as call information in addition to program data for controlling the exchange operation.

Next, the nurse call operation will be described with reference to FIG.
Now, when the call button 3a of the nurse call handset 3 is pressed, a call signal is sent to the corridor lamp 2. The corridor lamp 2 determines the type of the call signal, adds data such as the corridor lamp ID (room number) and bed number to the call signal, and transmits the call signal to the nurse call master unit 1.

When receiving a call signal from the corridor lamp 2 via the input / output interface 20, the nurse call master unit 1 decodes the received call signal, reads the call type, and rings the call sound corresponding to the call type. At the same time, the room number and bed number are decoded from the data on the call signal. If the room number and bed number are known, the calling patient is identified.
Next, databases used for patient identification and information display will be described.

FIG. 3 shows the configuration of various master files stored in the storage means 16 of the nurse call master unit 1.
“Patient data” is a master of basic patient information, and includes patient ID, name, and gender. It consists of date of birth, blood type, relief category, department, hospitalization date, doctor in charge, team in charge.

The “line data” is a master that defines the line data of the master unit and the slave unit address, and includes a slave unit ID (corresponding to the line data of the master unit), a room number, a bed number, a patient ID, and the like.
“Terminal allocation” is a master file indicating the affiliation of a mobile terminal, and is composed of a PSID that is an identification ID of the mobile terminal and an allocation destination, and a nursing team name or a patient ID is input to the allocation destination.

“Team formation” is a master file indicating the affiliation team for each nurse, and includes a nurse name and a nursing team name.
“Patient in charge” is a master file indicating which nursing team is in charge of each patient, and includes a patient ID and a nursing team name.

The management data in FIG. 4 is an example of an event file created from the various master files shown in FIG.
The data in FIG. 4 will be described in the top row. First, it can be seen that the parent device ID of the target parent device is “001”. It can also be seen that the bed number “1” of the hospital room number “101” is connected to the line number “001” indicated by the child machine ID, and the patient ID is “123456”.

Further, according to this data, the patients with the line numbers “001” to “008” are in charge of the team A, and the staff in charge is “No. 1” and “No. 2”. It can also be seen that the PSIDs of the mobile phone are “100” and “101”.

Note that a row with a background of network indicates that the patient portable terminal 7 is set for each line. That is, it is shown that the patient portable terminals with the PSIDs “200” and “300” are set for the patients with the line numbers “003” and “013”, respectively.

Here, let us return to the description of the calling operation of the nurse call master unit 1 again. First, the nurse call master unit 1 analyzes the call signal sent from the nurse call slave unit 3 and the corridor lamp 2, and searches the management data shown in FIG. 4 based on the data obtained by the analysis. Get the required data.

That is, a series of related data such as a patient ID, a team in charge, a staff PSID, and patient data can be acquired from the room number and bed number corresponding to the called nurse call slave unit 3, and necessary data such as a call The patient's hospital room number, bed number, patient name, etc. can be appropriately displayed on the liquid crystal screen.

During this call operation, the nurse call master device 1 creates and transmits a call signal for calling the mobile terminal toward the NC interface 8 of the main device 4. This calling signal includes the parent machine ID, the calling patient's room number, the bed number, and the staff PSID in the management data of FIG. A patient name, other patient information, etc. can be added as needed.

In the present embodiment, for example, two mobile terminals with PSIDs “100” and “101” are assigned to the nursing team “A”. In this case, both PSIDs are added to the call signal.

Next, a call signal from the nurse call master unit 1 is received by the central apparatus 11 via the NC interface 8, the communication path switch 9, and the data bus 13 of the main apparatus 4. The received data is stored in the storage device 12 by the operation of the central device 11.

By the way, in this embodiment, the identification number for identifying the portable terminal is defined as the PSID on the nurse call side and the portable terminal ID on the wireless side, and the numbers or symbols of both IDs are the nurse call system and the wireless system. They are usually different from each other in order to adapt to different interfaces.

Therefore, the storage device 12 stores in advance a number conversion table indicating the correspondence between the PSID used in the nurse call parent device 1 and the portable terminal ID used in the main device 4, and this number conversion table PSID and portable terminal ID can be converted mutually.
The number conversion function can be provided in the NC interface 8. In fact, there are many examples in which a CPU and a memory are mounted in the NC interface 8 and number conversion processing is executed.

When the central processing unit 11 receives the call signal from the nurse call base unit 1, the central processing unit 11 converts the PSID into a portable terminal ID, and also includes the calling patient's room number included in the call signal of the nurse call base unit 1, A call signal for wireless transmission including data such as a bed number and a message is created, and this call signal is transmitted to the wireless base station 5 via the communication path switch 9 and the wireless interface 10. By receiving the radio wave transmitted from the radio base station 5, the staff portable terminal 6 having the designated portable terminal ID is called.

When the staff mobile terminal 6 called as described above performs a response operation, the response signal is transmitted to the radio interface 10 of the main apparatus 4 via the radio base station 5 and via the speech path switch 9. Is received by the central processing unit 11. The central processing unit 11 decodes the response signal, converts it into a nurse call response signal, and transmits it to the NC interface 8.

When there are a plurality of staff mobile terminals 6 called from the nurse call master unit 1, a call recovery signal is sent via the main apparatus 4 and the radio base station 5 in order to restore the calling state of terminals other than the responding terminal. To the staff mobile terminal 9 to restore it.

The response signal transmitted from the NC interface 8 to the nurse call parent device 1 includes the PSID of the mobile terminal for the staff who responded. In the nurse call parent device 1, the PSID included in the data transmitted as the paging signal When the matching of the PSIDs included in the response signal is confirmed, response connection processing is performed, and the call operation of the nurse call parent device 1 is released. That is, the ringing of the ringing tone of the nurse call master unit 1 is stopped, and the nurse call slave unit 3 that has called the call is sent to the staff portable terminal 6 via the nurse call master unit 1, the main device 4, and the radio base station 5. The call is connected.

Unlike the above, if a response operation is performed in the nurse call parent device 1 before the staff portable terminal 6 responds, a response completion signal is sent from the nurse call parent device 1 to the main device 4 and the wireless base station 5. To the staff mobile terminal 6 to reset the calling state.

Next, the operation of calling the nurse call parent device 1 using the patient portable terminal 7 instead of the specific nurse call child device 3 will be described. For example, as shown by the management data in FIG. 4, regarding the child device ID, that is, the line number “003”, the patient portable terminal 7 is assigned and the PSID is “200”. In the following, it is assumed that the nurse call parent device 1 is called using the patient portable terminal 7. The operation flow at the time of calling is in accordance with the response operation of the staff portable terminal 6 described above.

That is, first, when a call operation is performed on the patient portable terminal 7, the call signal is received by the central processing unit 11 of the main apparatus 4 via the radio base station 5 and the radio interface 10. The central processing unit 11 stores the received data and transmits a call signal to the nurse call parent device 1 via the NC interface 8.

The nurse call master unit 1 reads “200” of the PSID data included in the call signal, and confirms that the patient with the line number “003”, that is, the patient ID “123458” is being called by the patient portable terminal 7. At the same time, based on the recognition result, necessary data, that is, the patient's room number, bed number, patient name, and patient information are taken out from the storage means 16 and displayed in the corresponding part of the call screen of the nurse call master unit 1. indicate.

In this case, it is desirable to display the name of the called patient differently so that the call from the nurse call handset 3 and the call from the patient portable terminal 7 can be distinguished by the nurse call base unit 1. The distinction between the two can be dealt with by changing the type of ringing tone in addition to the display.

The nurse call master device 1 sends back a call signal from the patient portable terminal 7 to the main device 4 in the same manner as when called from the nurse call slave device 3. As a result, in the main apparatus 4, a call signal for the staff portable terminal 6 is transmitted to the radio base station 5 under the control of the central processing unit 11, and the staff portable terminal 6 is called.

That is, the nurse call parent device 1 and the staff portable terminal 6 are called simultaneously by the calling operation of the patient portable terminal 7.
Therefore, if either the nurse call master unit 1 or the staff portable terminal 6 responds, the one responding first and the patient portable terminal 7 are connected to each other and can talk to each other.
In this case, the call state of the nurse call parent device 1 or the staff portable terminal 6 on the unanswered side is canceled.

When the nurse call master device 1 receives a call from the patient portable terminal 7 instead of the nurse call slave device 3, it is desirable to control the nurse call slave device 3 to be in a connection prohibited state. Then, even when the patient portable terminal 7 is operated in the vicinity of the nurse call slave unit 3, a howling failure due to mutual acoustic coupling between the nurse call slave unit 3 and the patient portable terminal 7 can be prevented.

Next, a case where the nurse call master unit 1 calls the nurse call slave unit 3 or the patient portable terminal 7 to make a call will be described.
First, when the patient portable terminal 7 is not set on the line of the nurse call slave unit 3, the description is omitted because it is the same as the conventional nurse call system.

Next, a case where the patient portable terminal 7 is set on the line of the nurse call slave unit 3 will be described.
Note that the line that is selected by the nurse call master unit 1 is the line number “003” where the patient PSID is specified in FIG.

First, when the channel number “003” is selected by the nurse call parent device 1, the calling signal is sent to both the patient portable terminal 7 and the nurse call child device 3.
That is, one call signal is sent to the main apparatus 4 via the input / output interface 14, and the designated patient portable terminal 7 is set to the call state from the main apparatus 4 via the wireless base station 5.

The other calling signal is sent to the nurse call handset 3 of the selected channel via the input / output interface 20 and the corridor lamp 2, and a ringing tone is generated.
In this state, by responding with either the patient portable terminal 7 or the nurse call slave unit 3, the call circuit is closed with the nurse call parent unit.

When performing a response operation, the patient portable terminal 7 may use a response button generally called a connection button or the like. In the nurse call handset 3, in this embodiment, the response button 3b can be used as shown in FIG. 1, but the present invention can be implemented without such a response button 3b.

For example, when calling the patient mobile terminal 7 and the nurse call handset 3, the patient mobile terminal 7 is first called for a certain time, and when the predetermined time has passed, the call for the patient mobile terminal 7 is forcibly reset, and then the nurse A configuration for automatically connecting to the call slave unit 3 can be easily considered.
