Nurse call system

Abstract

To provide a nurse call system capable of continuing setting operation on a display unit even when a call occurs and further even when the call is being answered.SOLUTION: A nurse call system includes a slave unit 1 installed at each bed for a patient to call a nurse, and a master unit 3 installed at a nurse station to announce occurrence of a call and respond to the call. The master unit 3 includes two display units 32: a first display unit 32a and a second display unit 32b, which display patient information. Each display unit 32 includes an operation unit 33 for making or changing settings related to patient nursing. When a call occurs due to operation of the slave unit 1 while either one of the display units 33 is displaying a setting screen in response to operation of the operation unit 33, a CPU 38 of the master unit causes one of the display units 32 that is undergoing setting operation to continue the setting operation by the operation unit 33 without displaying the occurrence of the call, and causes the other of the display units 32 to display the occurrence of the call.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a nurse call system, and more particularly to a nurse call system in which a parent unit installed in a nurse station has two display units that display various information. [Background technology]

[0002] A nurse call system is configured with a handset installed at each bed for patients to call a nurse, and a master unit installed at the nurse's station to notify the nurse of the call from the handset and for the nurse to respond. In addition to a relatively large first display unit that displays various information, including a list of patient information, the master unit is commonly equipped with a relatively small second display unit that displays information about the caller when a call is made from a handset. The parent unit, which has two displays like this, has the ability to perform various settings and display changes, and the two displays are equipped with operation units consisting of touch panels that allow for changing patient information and nursing information, playing back recorded footage of patients, and setting up mobile devices carried by nurses.

[0003] On the other hand, when a call was made from the handset, both displays displayed that a call had been made. This display was made even when the display was being operated. For example, if a call occurred while playing back a recorded image of a patient on the first display or while changing patient information, the call display was made on both screens, and operation could not be resumed until the call response was completed and the call display disappeared. Furthermore, in some cases, the setting operations performed up to that point are reset by the call display, and the user must wait until the response to the call is completed before starting over with the operation of opening the setting screen.

[0004] This call priority control was in place because when a call was made, responding to the call took priority over setting operations, but in recent nurse call systems, nurses can respond using their own mobile devices, so the nurse performing the setting operations on the display unit does not necessarily have to respond. This means that even if a call is made by a patient, the nurse performing the setting operations can continue setting up the system. In light of this, a system has been proposed that allows users to continue setting operations even if a call is made from a handset. For example, in Patent Document 1, even if a call is made while users are performing setting operations, the system is configured so that users can continue setting operations from the point where they were interrupted after answering the call. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2017-79404 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the nurse call system of Patent Document 1 mentioned above, when a call is received from a patient during setup operations on the first display unit which displays a list of patient information, etc., the data being set up is saved and a call display is displayed; once the response is completed and the system returns to a standby state, setup can be continued. However, since the setting operation cannot be performed and is interrupted from the start of the call display until the response is completed, even if the setting operation can be continued, the work cannot be performed smoothly.

[0007] In view of the above problems, the present invention has an object to provide a nurse call system that allows the user to continue setting operations on the display unit even when a call has been made and even while the call is being answered. [Means for solving the problem]

[0008] In order to solve the above problems, the first configuration of the present invention is a nurse call system that has a handset installed at each bed so that a patient can call a nurse, and a parent unit installed at a nurse's station to notify and respond to a call, and the parent unit has two display units, a first display unit and a second display unit, which display patient information, and when a call is made by operating the handset, at least one of the two display units displays the call, and each display unit is equipped with an operation unit for setting or changing settings related to patient care, and even if a call is made by operating the handset while either display unit is displaying a setting screen in response to operation of the operation unit, the one display unit during the setting operation continues the setting operation by the operation unit and does not display the call, and has a call display control unit that causes the other display unit to display the call. According to this configuration, when one of the two display units is displaying the setting screen, even if a call occurs, the display unit displaying the setting screen can continue the setting operation without displaying the call occurrence. Therefore, even if a call occurs and even if the call is being answered, the nurse performing the setting operation can continue the setting work.

[0009] A second configuration of the present invention is a nurse call system having a sub-unit installed at each bed so that a patient can call a nurse, and a parent unit installed at a nurse's station to notify and respond to a call, the parent unit having two display units, a first display unit and a second display unit, which display patient information, and when a call is made by operating the sub-unit, at least one of the two display units displays that a call has been made.The display units each have an operation unit for making settings or changing settings related to patient care, and when a call is made by operating the sub-unit while both display units are in a state where a setting operation is being performed in response to operation of the operation unit, one of the display units is selected as the display unit that displays the call has been made based on preset conditions, and the function of the operation unit of that display unit is stopped until the response to the call is completed to display that the call has been made, and the other display unit during the setting operation has a call display control unit that causes the setting operation by the operation unit to continue without displaying that a call has been made. According to this configuration, even if both display units are displaying the setting screen by the operation of the operation unit, when a call is generated, one of the display units selected based on the preset conditions stops the setting operation and displays the occurrence of the call until the response to the call is completed. Therefore, even if both display units are performing setting operations, the occurrence of the call is reliably displayed and the call is not ignored, and the other display unit displaying the setting screen can continue the setting operation without displaying the occurrence of the call even if a call is generated and even if the call is being responded to.

[0010] Another aspect of the present invention is characterized in that, in the above configuration, when a call occurs due to operation of the handset while both display units are displaying a setting screen in response to operation of the operation unit, the call display control unit causes one of the display units for which a longer time has passed since the last operation to display the occurrence of a call. With this configuration, even if both display units are being operated, the call occurrence display is made on the display unit on which the setting operation has been suspended for the longer period, so there is a low probability that the call display will be made on the display unit which is being operated without suspension, thereby reducing the impact of operation interruption due to the call display.

[0011] Another aspect of the present invention is characterized in that, in the above configuration, the call display control unit restores the functions of the operation unit that had been stopped on the display unit that displayed the occurrence of a call when the response to the call is completed, making it possible to resume setting operations from the interrupted state. With this configuration, operations using the operating unit are interrupted when a call is received, but the setting operations can be resumed once the response to the call has been completed, and can be continued from the interrupted state, thereby reducing the burden on the nurse working. Effect of the Invention

[0012] According to the present invention, when one of the two display units is displaying a setting screen, even if a call occurs, the display unit displaying the setting screen can continue the setting operation without displaying the call occurrence. Therefore, even if a call occurs and even if the call is being answered, the nurse performing the setting operation can continue the setting work. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a block diagram showing an example of a nurse call system according to the present invention. The nurse call system 10 includes a handset 1 installed at each bed for a patient to call a nurse, a corridor light 2 installed at each hospital room for indicating the occurrence of a call by the handset 1, a master unit 3 installed at a nurse's station for responding to a call made by the handset 1, a controller 4 for controlling communication between devices, a mobile terminal 5 carried by a nurse to respond to a call, such as a smartphone, a camera 6 installed in a hospital room for capturing an image of a patient, etc. Reference numeral 8 denotes a base station that communicates with the mobile terminal 5, and 9 denotes a private branch exchange (PBX) that manages communication with the mobile terminal 5.

[0015] The corridor light 2, the base unit 3, the control unit 4, the camera 6, and the PBX 9 are connected via a LAN line L1 installed in the hospital. The handset 1 is connected to the corridor light 2 via a transmission line L2.

[0016] The handset 1 has a call grip button (call button) 1a and a plate handset 1b that sends out a call signal in response to operation of the call button 1a and is equipped with a call section 11 for making a call, and the call button 1a is connected to the plate handset 1b.

[0017] The corridor light 2 has an indicator light 21 that indicates the occurrence of a call by operating the handset 1, and a patient information display unit 22 that displays patient information. It also has a function of relaying a call signal sent from the handset 1, a function of relaying a call between the base unit 3 or the mobile terminal 5 and the handset 1, and a function of relaying an image captured by the camera 6.

[0018] The control device 4 controls the communication between the child device 1 and the parent device 3, and the communication between the child device 1 and the mobile terminal 5. It also has a storage unit that saves images captured by the camera 6 and stores various setting information.

[0019] Fig. 2 shows a functional block diagram of the base unit 3. As shown in Fig. 2, the base unit 3 includes a handset 31 constituting a communication section, two display sections 32 (a first display section 32a and a second display section 32b), an operation section 33 for changing the display on the display section 32 and for performing setting operations related to patient care (a first operation section 33a for performing display change / setting operations on the first display section 32a and a second operation section 33b for performing display change / setting operations on the second display section 32b), a display control section 35 for controlling the display on the display section 32 (a first display control section 35a for controlling the display on the first display section 32a and a second display control section 35b for controlling the display on the second display section 32b), an alarm section 36 for sounding a ring tone, etc., a voice processing section 37 for controlling the call by the handset 31 and the alarm sound of the alarm section 36, an information storage section 34 for storing patient / nurse information, etc., a base unit CPU 38 for controlling the base unit 3, a base unit communication IF 39 for communicating with the controller 4, etc. via a LAN line L1, etc. The master CPU 38 has a function as a call display control unit that causes the display unit 32 to display a call.

[0020] The first display unit 32a is configured, for example, by a 32-inch large-screen LCD and displays a list of patient information, etc. The second display unit 32b is configured, for example, by a 7-inch small-screen LCD and is provided near the handset 31 to display caller information, etc. The first operation unit 33a is formed by providing a touch panel on the first display unit 32a, and by touching a predetermined portion of the first display unit 32a, a setting screen can be popped up and various display changes related to patient care, updating patient information, changing the display layout, etc. Also, as described later, a plurality of operation buttons made of a touch panel forming part of the first operation unit 33a are arranged on the periphery of the screen of the first display unit 32a, and a whiteboard display, etc. can be performed with one touch.

[0021] The second operation unit 33b is formed by providing a touch panel on the second display unit 32b, and by touching a specific portion of the second display unit 32b, a keyboard or the like which constitutes the second operation unit 33b can be displayed on the second display unit 32b, and settings related to patient care such as registering patient information, setting / playing back the camera 6, setting the nursing team, and setting the mobile terminal 5 can be made.

[0022] The nurse call system 10 configured as described above operates as follows. However, the operation of making a call by operating the handset 1 (hereinafter referred to as a "nurse call") and the response operation by the base unit 3 or mobile terminal 5 are the same as in the past, so explanations are omitted. Here, the explanation focuses on the display operation of the base unit 3 when a nurse call is generated. The display (call display) of the parent unit 3 in response to a nurse call varies depending on the state: a first display state in which neither the first operation unit 33a nor the second operation unit 33b are operated; a second display state in which the first operation unit 33a is in an operating state, an operation screen is displayed on the first display unit 32a, and the second operation unit 33b is not operated; a third display state in which the second operation unit 33b is in an operating state, an operation screen is displayed on the second display unit 32b, and the first operation unit 33a is not operated; and a fourth display state in which both the first operation unit 33a and the second operation unit 33b are operated, which will be explained in order below.

[0023] The parent unit CPU 38 recognizes which of these four display states the display unit 32 is currently in, and when a nurse call occurs, operates the display unit 32 as follows according to the state of the display unit. When a nurse call occurs in the first display state, the first display unit 32a and the second display unit 32b both display the occurrence of the nurse call (call display). At the same time, a ring tone is sounded from the alarm unit 36. This call display causes detailed information about the patient, including the name of the patient who made the call, to be displayed on both display units 32. The call display will continue until the call is answered. The call tone will sound regardless of the display format.

[0024] When a nurse call occurs in the second display state, the first display unit 32a does not display the call, but the second display unit 32b displays the call. The first display unit 32a continues to display the setting screen, and accepts operations of the first operation unit 33a even during a call / response, allowing the setting operation to be continued. Fig. 3 shows this state. That is, it shows the display operation when a nurse call occurs while the first display unit 32a is undergoing a setting operation. In this case, only the second display unit 32b displays the call. The second display unit 32b switches to the call display screen P2, and displays the name of the patient who made the call, related information, etc.

[0025] The first display section 32a shows a state where the setting screen R1 is popped up, and here shows a state where a patient information change screen, which is one of the setting screens R1, is displayed. Even if a nurse call occurs, this display state does not change, and patient information can be continuously updated. In Fig. 3, P1 shows a list of patient information, and this list is displayed during standby, and multiple areas B displayed on the periphery of the first display section 32a constitute a first operation section that can be operated with one touch.

[0026] The controller 4 also notifies the mobile terminal 5 of the occurrence of this nurse call, and when the call is answered by the base unit 3 or the mobile terminal 5, the ringing stops and a communication path is established between the device that answered and the handset 1. When the answering is completed, the second display unit 32b returns to the display state before the nurse call occurred.

[0027] When a nurse call occurs in the third display state, the second display unit 32b does not display the call, but the first display unit 32a displays the call. The second display unit 32b continues to display the setting screen R1, and the setting operation can be continued by the second operation unit 33b even during the call / response. Figure 4 shows this state, with the call display in response to a nurse call occurring being implemented by a pop-up display R2. In this case, only the first display section 32a displays the call. Here, the second display section 32b shows a state in which an operation screen P4 for selecting the display of the image captured by the camera 6, which is one of the setting screens R1, is displayed, and this setting can be continued even if a nurse call occurs. The first display section 32a shows a state in which a call display is being performed in a standby state in which the patient information list P1 is displayed.

[0028] If a nurse call occurs in the fourth display state, the display unit 32 for which a longer time has passed since the last operation, i.e., the display unit 32 for which operation has been interrupted for a longer period of time, will display a call. The parent unit CPU 38 knows the time of the last operation of the setting operations of the first display unit 32a and the second display unit 32b, and is set to display a call on the display unit 32 for which no operation has been performed for a longer period of time and operation has been interrupted, even if the setting screen R1 (operation screen P4) is displayed. Therefore, for example, if the operation of the first operating section 33a is interrupted longer than the operation of the second operating section 33b, the first display section 32a displays the call. 5 shows this state, in which the setting screen R1 is displayed as a pop-up in the first display section 32a, and a call display is further performed as a pop-up display R2 in the first display section 32a, while the display in the second display section 32b does not change. The second display section 32b shows a state in which the operation screen P4 for selecting the display of the image captured by the camera 6 is displayed, similarly to FIG.

[0029] In this way, the display unit 32 that displays the call in response to a nurse call has the setting operation suspended while the call display is displayed; however, because the display control unit 35 maintains the display indicating that the setting operation is in progress, once the nurse call response is completed and the call display disappears, it is possible to resume the setting operation from the suspended state. If the interruption time of the setting operation of the second operation section 33b is longer, a call display is made on the second display section 32b in response to the occurrence of a nurse call. In this case, the display form is the same as that shown in FIG.

[0030] In this way, when one of the two display units 32 is displaying the setting screen R1 by operating the operation unit 33, even if a nurse call occurs, the one displaying the setting screen R1 can continue the setting operation without displaying the occurrence of a call. Therefore, even if a call occurs and even if the call is being answered, the nurse performing the setting operation can continue the setting work. Furthermore, even if both display units 32 are displaying the setting screen R1 by operation of the operation unit 33, upon receiving a nurse call, the one display unit 32 selected based on the preset conditions stops the setting operation and displays the occurrence of a call until the response to the nurse call is completed. Therefore, even if both display units 32 are in the middle of setting operation, the occurrence of a call is reliably displayed, and the nurse call is not ignored, and the other display unit 32 displaying the setting screen R1 can continue the setting operation without displaying the occurrence of a call, even if a nurse call occurs and even if it is being responded to. Furthermore, although operations using the operating unit 33 are interrupted when a nurse call occurs, the setting operations can be resumed once the response to the nurse call has ended, and can be continued from the interrupted state, thereby reducing the burden on the nurses working. Furthermore, even if both display units 32 are being operated, the occurrence of a call is displayed on the display unit 32 on which the setting operation has been suspended for the longer period, so there is a low probability that the call display will be displayed on the display unit 32 that is being operated without interruption, thereby reducing the impact of operation interruption due to the call display.

[0031] In the above embodiment, when both display units 32 are in a setting operation state, the display is managed based on the length of the operation interruption time, but the display unit 32 that displays the call occurrence may be managed based on the setting content without being managed based on the operation interruption time. For example, when the mobile terminal 5 is being set, the setting operation may be prioritized regardless of the operation interruption time, and the call display may be performed regardless of the setting content of the other display unit 32. In addition, when the setting operation is interrupted by displaying an incoming call on the display unit 32, if the operation is not resumed for a certain period of time (e.g., 60 seconds) after the response is completed, the operation may be automatically terminated and the display may return to the standby screen.
