Description

The present invention relates to a nurse call system, in particular, a nurse call system in which a call is made by pressing a call button of a nurse call slave unit, and a call is notified in a nurse call master unit or the like in response to the call. It is suitable for use.

Generally, a nurse call system is used in hospitals and long-term care facilities. The nurse call system is used when a hospital patient needs the support of a doctor or nurse, or when a caregiver in a nursing facility needs the support of a caregiver, the patient or care recipient (hereinafter, simply "" This system is designed so that a "patient") can call a doctor, a nurse, or a caregiver (hereinafter, simply referred to as a "nurse") by pressing a call button or the like.

Many nurse call systems are configured to include a nurse call slave unit installed at the bedside, toilet, bathroom, etc., and a nurse call master unit installed at the nurse station. In addition, a nurse call system that combines a PHS (Personal Handyphone System) terminal carried by a nurse and a PBX (Private Branch Exchange) is also provided (see, for example, FIG. 2 of Patent Document 1). In this type of nurse call system, when the patient presses the call button of the nurse call slave unit to make a call, the PHS terminal or the nurse call master unit notifies that the call has been made. When the nurse responds to this with the PHS terminal he or she carries, the handset of the nurse call master unit, etc., a communication path is formed with the nurse call slave unit, and it is possible to make a call. Become.

FIG. 4 of Patent Document 1 also discloses a nurse call system in which a PBX and a SIP server are used in combination and an IP phone (smartphone) is provided instead of a PHS terminal. In the nurse call system shown in FIG. 4, the alarm information generated by pressing the call button is transmitted to the PBX through the non-web type line, then converted into the web type communication standard by the SIP server, and then the LAN line in the hospital. Is transmitted to the IP phone via a web-type line such as a wireless LAN access point. With an IP phone, an incoming call alarm sounds and a nurse performs a reply operation to enable a voice call.

In the nurse call system described in FIG. 4 of Patent Document 1, the PBX transmits alarm information to the transmission history management means in parallel with the above operation. The transmission history management means creates a transmission history record in which the acquired alarm information is arranged in order of transmission time. The created outgoing call history record can be referred to by an IP phone. Further, the alarm information message transmitting means acquires new alarm information from the transmission history management means and transmits it to the IP phone as a push-type alarm information message. Here, the alarm information message is transmitted to the message server outside the hospital via the web without going through the SIP server. The message server directly transmits the alarm information message to the pre-registered IP phone group. The IP phone receives the alarm information message and displays the message or calls attention by voice.

As shown in FIG. 2, the controller 2 includes a call reception unit 21, a notification processing unit 22, a response reception unit 23, a call path forming unit 24, and a restoration reception unit 25 as functional configurations. Further, the nurse call master unit 1 includes a management information storage unit 20 as a storage medium.

Each of the above functional blocks 21 to 25 can be realized by any of hardware configuration, DSP (Digital Signal Processor), and software. For example, when realized by software, each of the above functional blocks 21 to 25 is actually configured to include a computer CPU, RAM, ROM, etc., and is a program stored in a recording medium such as RAM, ROM, hard disk, or semiconductor memory. Is realized by the operation of.

The management information storage unit 20 stores information about the patient (hereinafter referred to as patient information), information about the nurse (hereinafter referred to as nurse information), and information regarding the call destination of the nurse call (hereinafter referred to as call destination information). It is memorized as management information about the nurse call.

The patient information includes, for example, the patient's name, age, gender, room number of the hospital room, the bed number for identifying the bed used by the patient, the patient ID for identifying the patient, and the hand-held handset used by the patient 5. Includes various information such as a slave unit ID for identifying. Further, the nurse information identifies, for example, the name of the nurse, the nurse ID for identifying the nurse, the patient ID for identifying the patient in charge, and the portable nurse call master unit 9 used by the nurse. Includes various information such as the master unit ID for the nurse.

The call destination information includes a patient (for example, a patient ID), a nurse in charge (for example, a nurse ID) who notifies in response to a call from the patient, and a portable nurse call parent possessed by the nurse in charge. It is stored in association with the master unit ID of the machine 9 and information (extension number, etc.) regarding the call destination. When performing team nursing in which one patient is supported by a plurality of nurses, one patient, a plurality of nurses, and a plurality of portable nurse call master units 9 possessed by each nurse are grouped. It will be remembered.

The call reception unit 21 receives a call from the patient (hand-held handset 5). That is, the call reception unit 21 receives the call signal sent from the hand-held handset 5 via the wall-embedded handset 4 and the corridor light 3. When the call reception unit 21 accepts the call, the call reception unit 21 performs a process for outputting a ring tone for notifying the patient that the call is in the call state from the speaker of the handset handset 5, and such a call. The state is continued until a predetermined operation described later is performed.

When the call reception unit 21 receives a call from the patient (when the call signal transmitted from the hand-held handset 5 is received), the notification processing unit 22 causes the nurse call master units 1 and 9 to execute the notification operation. In addition to controlling the above, the terminal control device 11 is instructed to control the terminals 13 and 14 to execute the notification operation.

Here, the notification process for the stationary nurse call master unit 1 is performed as follows. That is, the notification processing unit 22 stores management information based on the handset information transmitted by the call signal received by the call reception unit 21 (such as the handset ID for identifying the hand-held handset 5 that made the call). The patient who made the call is identified by reference to Part 20. Then, the notification processing unit 22 reads a part of the patient information (for example, name, age, gender, room number, bed number, etc.) about the specified patient from the management information storage unit 20, and the stationary nurse together with the call type information. Send to call master unit 1. The stationary nurse call master unit 1 generates a notification screen on the display and displays the patient information and the call type received from the controller 2. Further, the stationary nurse call master unit 1 outputs a predetermined notification sound from the speaker.

Further, the notification process for the portable nurse call master unit 9 is performed as follows. That is, the notification processing unit 22 reads the call destination information of the nurse in charge of the patient from the management information storage unit 20 after identifying the patient who made the call as described above, and uses the read destination information as the read destination information. Based on this, the notification to the plurality of portable nurse call master units 9 grouped for team nursing is executed. For example, a known slide calling function is used to sequentially execute notifications to a plurality of portable nurse call master units 9.

Specifically, the notification processing unit 22 sequentially issues a call signal instructing the PBX 7 to execute notification to the plurality of portable nurse call master units 9 via the handheld call main unit 6 at predetermined time intervals. Send to. This call signal includes a part of patient information (for example, name, age, gender, room number, bed number, etc.) and call type information about the patient specified by the notification processing unit 22. When the PBX 7 receives a call signal from the controller 2 via the handheld call main unit 6, the PBX 7 executes a call to the portable nurse call master unit 9 designated as the call destination. Upon receiving this call signal, the portable nurse call master unit 9 displays the patient information and the call type on the display, and outputs a predetermined notification sound from the speaker.

Further, the notification processing for the terminals 13 and 14 is performed as follows. That is, the notification processing unit 22 transmits instruction information instructing the terminal control device 11 to execute the notification to the terminals 13 and 14. This instruction information includes a part of patient information (for example, name, age, gender, room number, bed number, slave unit ID, etc.) and call type information regarding the patient specified by the notification processing unit 22. .. When the terminal control device 11 receives the instruction information from the controller 2, the terminal control device 11 instructs the execution of the notification operation by transmitting the instruction information to the terminals 13 and 14 via the AP 12. The terminals 13 and 14 that have received this instruction information display the patient information and the call type on the display. At this time, a predetermined notification sound may be output from the speaker.

FIG. 4 is a diagram showing an example of a notification screen displayed on the terminals 13 and 14. Here, as an example, an example of a notification screen displayed on the electronic medical record terminal is shown. As shown in FIG. 4A, when the electronic medical record terminal receives the notification operation instruction information from the terminal control device 11, the electronic medical record terminal pops up the notification screen 40 on the main screen displaying the electronic medical record information. The patient information and the call type are displayed on the notification screen 40.

FIG. 4B shows a display example of the notification screen 40. As shown in FIG. 4B, the call type 41 and the patient information 42 are displayed on the notification screen 40. Further, the notification screen 40 also displays a response button 43 for a nurse or another hospital staff using the electronic medical record terminal to perform a response operation. When a nurse or the like operates the response button 43, a response notification notifying that the response button 43 has been operated is transmitted to the terminal control device 11, and further transmitted from the terminal control device 11 to the controller 2. The response notification includes a terminal ID for identifying the terminal that operated the response button 43.

It will be described back to FIG. The response reception unit 23 receives the response notification from the nurse call master units 1 and 9 or the terminals 13 and 14 whose notification operation is executed by the notification processing unit 22. For example, when a nurse off-hooks the handset of the stationary nurse call master unit 1 to answer a call from a patient, a response notification notifying that the stationary nurse call master unit 1 has been off-hooked is sent to the stationary nurse call master unit. It is transmitted from 1 to the controller 2 and received by the response reception unit 23.

Further, when the nurse off-hooks the portable nurse call master unit 9 to answer the call from the patient, a response notification notifying that the portable nurse call master unit 9 has been off-hooked is sent via the handy nurse call main unit 6. Is transmitted to the controller 2 and received by the response reception unit 23.

In addition, when a nurse or other hospital staff operates the response button 43 on the terminals 13 and 14 to answer a call from the patient, a response notification is sent to the terminal 13 and 14 notifying that the response button 43 has been operated. It is transmitted to the controller 2 via the control device 11 and received by the response reception unit 23.

The response receiving unit 23 controls the notification processing unit 22 so as to stop the notification operation of the nurse call master units 1 and 9 and the terminals 13 and 14 when receiving the response notification transmitted from the nurse call master units 1 and 9. To do. Further, the response reception unit 23 controls the call reception unit 21 so as to stop the call state from the hand handset 5 (the state in which the hand handset 5 is ringing), and the hand handset 23 The call path forming unit 24 is controlled so as to form a call path between the 5 and the nurse call master units 1 and 9.

Further, when the terminal control device 11 notifies that the terminal control device 11 has received the response notification transmitted from the terminals 13 and 14, the response reception unit 23 maintains the call state from the handset handset 5. While doing so, the notification processing unit 22 is controlled so as to stop the notification operations of the nurse call master units 1 and 9 and the terminals 13 and 14. The ringing state is maintained for the following reasons.

That is, when the response operation to the call is performed on the terminals 13 and 14, the patient cannot make a call with the nurse because the communication path is not formed with the handset handset 5. In such a case, if the ringing state is stopped in response to the response operation on the terminals 13 and 14 and the output of the ringing tone is stopped from the handset handset 5, did the patient respond by the nurse? It is not possible to determine if the call has been interrupted due to some problem. Therefore, the patient may feel anxious.

Therefore, when the response operation is performed on the terminals 13 and 14, the output of the ringing tone to the handset handset 5 is continued so that the patient can know that the call is in progress. In this case, when the nurse or the like who responded with the terminals 13 and 14 goes to the patient's room and operates the recovery button of the wall-embedded handset 4, the calling state of the hand-held handset 5 is stopped. .. That is, when the restoration button of the wall-embedded handset 4 is operated, the restoration signal is transmitted to the controller 2 via the corridor light 3 and received by the restoration reception unit 25. The restoration reception unit 25 notifies the call reception unit 21 that the restoration signal has been received. Upon receiving this notification, the call reception unit 21 stops the call state of the handset handset 5.

FIG. 3 is a block diagram showing a functional configuration example of the terminal control device 11. As shown in FIG. 3, the terminal control device 11 includes a notification instruction receiving unit 31, a notification unit 32, a response notification receiving unit 33, a response notification unit 34, and a notification designation unit 35 as functional configurations. Further, the terminal control device 11 includes a designated information storage unit 30 as a storage medium.

Each of the above functional blocks 31 to 35 can be configured by any of hardware, DSP, and software. For example, when configured by software, each of the above functional blocks 31 to 35 is actually configured to include a computer CPU, RAM, ROM, etc., and is a program stored in a recording medium such as RAM, ROM, hard disk, or semiconductor memory. Is realized by the operation of.

The notification instruction receiving unit 31 receives the notification operation execution instruction information for the terminals 13 and 14 transmitted by the notification processing unit 22 of the controller 2. The notification unit 32 transmits the instruction information received by the notification instruction reception unit 31 to the terminals 13 and 14 via the AP 12, so that the notification screen 40 as illustrated in FIG. 4 is displayed on the terminals 13 and 14. Display it. The instruction information transmitted by the notification unit 32 to the terminals 13 and 14 does not have to have the same format as the instruction information received from the controller 2 by the notification instruction reception unit 31, and the terminals 13 and 14 accept the instruction information. It may be converted into a possible format.

The response notification receiving unit 33 receives a response notification notifying that the response button 43 has been operated from the terminals 13 and 14 on which the response button 43 displayed on the notification screen 40 has been operated. The response notification unit 34 transmits the response notification received by the response notification reception unit 33 to the controller 2. The response notification transmitted by the response notification unit 34 to the controller 2 does not have to have the same format as the response notification received by the response notification receiving unit 33 from the terminals 13 and 14, and is accepted by the controller 2. It may be converted into a possible format.

The notification designation unit 35 receives a call from which hand-type handset 5 and performs a notification operation to the terminals 13 and 14, or rejects a call from which hand-type handset 5 and notifies the terminals 13 and 14. It is specified whether or not to perform the operation, and the specified contents are stored in the designated information storage unit 30. The designated information is composed of, for example, the slave unit ID of the hand-held slave unit 5 that performs (or does not perform) the notification operation. The designated operation of the hand-held handset 5 that performs (or does not perform) this notification operation is, for example, to access the terminal control device 11 from the terminals 13 and 14 via the AP12 and use the operation unit of the terminals 13 and 14 for nursing. It can be done by a teacher or the like.

The notification unit 32 performs a notification operation based on the slave unit ID included in the instruction information received by the notification instruction receiving unit 31 and the designated information (slave unit ID) stored in the designated information storage unit 30. The execution of the notification operation to the terminals 13 and 14 is controlled only when the notification operation is instructed in response to the call from the handset handset 5 designated to be performed.

Even if the notification operation for the terminals 13 and 14 is not executed according to the content specified by the notification designation unit 35, the notification operation for the nurse call master units 1 and 9 is executed. Therefore, a nurse or the like using the terminals 13 and 14 can arbitrarily specify the hand-held handset 5 to be notified (or not performed) in consideration of business convenience and the like.

Here, an example has been described in which the designated information of the hand-held handset 5 is stored in the terminal control device 11, and the terminal control device 11 determines whether or not to transmit the notification operation instruction information to the terminals 13 and 14. , The present invention is not limited to this. For example, the designated information is transmitted from the terminal control device 11 to the controller 2 and stored in the controller 2. Then, the controller 2 may decide whether or not to transmit the instruction information of the notification operation to the terminal control device 11 according to the designated information. In this case, transmitting the designated information from the terminal control device 11 to the controller 2 and storing it corresponds to controlling the execution of the notification operation to the terminals 13 and 14 according to the designated contents.

FIG. 5 is a flowchart showing an operation example of the controller 2 configured as described above. First, the call reception unit 21 of the controller 2 determines whether or not the call signal sent from the handset handset 5 has been received (step S1). If the call signal has not been received, the determination in step S1 is repeated. On the other hand, when the call reception unit 21 receives the call signal, the notification processing unit 22 controls the nurse call master units 1 and 9 and the terminals 13 and 14 to execute the notification operation (step S2).

After that, the response reception unit 23 determines whether or not the response notification has been received (step S3). If the response notification has not been received, the determination in step S3 is repeated. On the other hand, when the response reception unit 23 receives the response notification, the response reception unit 23 determines whether or not it is the response notification transmitted from the terminals 13 and 14 (step S4). Here, when the response reception unit 23 receives the response notification from the terminal control device 11, it determines that it is the response notification transmitted from the terminals 13 and 14.

When the response reception unit 23 determines that the response notification is transmitted from the terminals 13 and 14, the response reception unit 23 maintains the call state from the hand-held handset 5 and the nurse call master units 1 and 9 and the terminals 13 and 14 The notification processing unit 22 is controlled so as to stop the notification operation (step S5).

After that, the restoration reception unit 25 determines whether or not the restoration signal sent from the wall-embedded handset 4 has been received (step S6). If the recovery signal has not been received, the determination in step S6 is repeated. On the other hand, when the recovery reception unit 25 receives the recovery signal, the call reception unit 21 stops the call state from the handset handset 5 (step S7). As a result, the processing of the flowchart shown in FIG. 5 is completed.

In step S4, when it is determined that the response notification received by the response reception unit 23 is not transmitted from the terminals 13 and 14, that is, the response notification is transmitted from the nurse call master units 1 and 9, a response is made. The reception unit 23 controls the call reception unit 21 so as to stop the call state from the hand-held handset 5, and also performs a notification process so as to stop the notification operations of the nurse call master units 1 and 9 and the terminals 13 and 14. The unit 22 is controlled (step S8).

Next, the response reception unit 23 controls the call path forming unit 24 so as to form a call path between the hand-held handset 5 and the nurse call master units 1 and 9 (step S9). As a result, the processing of the flowchart shown in FIG. 5 is completed. When the on-hook operation is performed on the nurse call master units 1 and 9 after forming the call path, the call path formed between the nurse call master units 1 and 9 and the handset slave unit 5 is disconnected. To.

As described in detail above, in the present embodiment, when the controller 2 receives the call signal transmitted from the hand-held handset 5, the nurse call master units 1 and 9 are connected via the nurse call trunk line. Is controlled to execute the notification operation, and the terminal control device 11 connected via the computer network (LAN) is instructed to cause the terminals 13 and 14 to execute the notification operation.

As described above, according to the present embodiment, the controller 2 is configured to be able to control the terminals 13 and 14 via the terminal control device 11 via a computer network different from the nurse call trunk line, and thus is a hand type. Even terminals 13 and 14 that do not have a telephone function that enable a call by answering a call from the handset 5 are notified of a call from the handset handset 5 through control from the controller 2 to the terminal control device 11. can do.

Further, in the present embodiment, when the response button 43 is operated on the terminals 13 and 14 in response to the notification operation corresponding to the call from the hand-held handset 5, the controller 2 causes the hand-held handset 5 to operate. While maintaining the ringing state from (while continuing to output the ringing tone), the notification operation of the nurse call master units 1 and 9 and the terminals 13 and 14 is stopped.

With this configuration, when a response operation is performed on the terminals 13 and 14 in which a communication path is not formed with the handset handset 5, the nurse or the like who performed the response operation goes to the patient's room. Until the recovery button of the wall-embedded handset 4 is operated, the handset 5 continues to output a ringing tone. Therefore, the patient who made the call does not have to wait in a state where he / she cannot talk to the nurse after the ringing tone is interrupted. As a result, it is possible to prevent the patient from feeling anxious.

In the above embodiment, when a response operation is performed on the nurse call master units 1 and 9 or the terminals 13 and 14, a response notification is transmitted to the controller 2 and the nurse call master units 1 and 9 are transmitted from the controller 2. An example of stopping the notification operation by instructing the terminals 13 and 14 has been described, but the present invention is not limited to this. For example, the notification operation of the nurse call master units 1 and 9 or the terminals 13 and 14 that have responded may be stopped by themselves without being instructed by the controller 2.

Further, in the above embodiment, an example in which the ringing state of the hand-type handset 5 is stopped by operating the recovery button of the wall-embedded handset 4 has been described, but the recovery button of the wall-embedded handset 4 is This is just an example, and other recovery operations may be performed. For example, the calling state of the hand-held handset 5 may be stopped by operating the recovery button provided on the corridor light 3. Alternatively, the calling state of the hand-held handset 5 may be stopped by operating a recovery button provided on another device installed in the hospital room.

Further, in the above embodiment, an example in which the stationary nurse call master unit 1 and the controller 2 are separately configured has been described, but the present invention is not limited to this. For example, the controller 2 may be omitted, and the function of the controller 2 may be provided in the stationary nurse call master unit 1. In this case, the information transmitted from the controller 2 to the stationary nurse call master unit 1 and the information transmitted from the stationary nurse call master unit 1 to the controller 2 are internally stored by the stationary nurse call master unit 1. Will be processed.

Further, in the above embodiment, when a response operation is performed on the terminals 13 and 14 in which a communication path is not formed with the hand-held handset 5, the nurse or the like who performed the response operation goes to the patient's room. If you forget, the ringing tone will continue to be output from the handset handset 5, but in order to prevent this, the time from the response operation to the recovery operation on the terminals 13 and 14 is measured. A timer may be provided in the terminal control device 11 or the like so that the terminals 13 and 14 perform the notification operation again when the recovery operation is not performed even after a predetermined time has elapsed since the response operation was performed. ..

In addition, the above embodiments are merely examples of embodiment of the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be practiced in various ways without departing from its spirit or its main features.
