Description

  The present invention relates to a nurse call system for calling a medical staff in response to a request from a patient in a hospital or the like.

  The nurse call system installed in facilities such as hospitals and welfare facilities consists of a nurse call master unit installed in the nurse center, a corridor lamp installed in the hospital room and connected to the nurse call master unit, and a bed for each patient. Each is provided with a wall-embedded handset that is installed on the wall surface in the hospital room and connected to the corridor lamp.

  The wall-embedded handset is equipped with a call button, a microphone, and a speaker for calling a medical worker, so that it can communicate with the nurse call master unit side, but it can be connected to an outlet provided on the surface. By attaching the nurse call cordless handset, the nurse call cordless handset attached to the outlet can also communicate with the nurse call master phone side. Here, the nurse call slave unit is detachable from the outlet of the wall-embedded slave unit.

  Examples of such nurse call slaves include a grip push button and a hand-type slave. Here, the grip push button is provided with a call button, and is only for calling and has no call function. In addition to the call button, the hand-type handset has a built-in microphone and speaker and has a call function.

By the way, in a nurse call system, there is known a system in which a drop call is applied when an abnormality such as drop or disconnection occurs in a nurse call slave (for example, Patent Document 1).
Japanese Patent Laid-Open No. 2004-112015

  In the nurse call system described in Patent Document 1, the nurse call slave unit is provided with a power supply circuit that receives external power and supplies power to each circuit in the main body, and further, between the power supply circuit and each circuit in the main body. The power supply disconnecting circuit is provided so that when the power supply is stopped, the power supply disconnecting call is made.

  There is also known an example in which a changeover switch that can suspend notification of disconnection / disconnection of a nurse call slave unit is provided in a wall-embedded slave unit. In addition, an example is known in which a drop call is made after a predetermined time has elapsed since the nurse call slave is dropped.

  In the technique described in Patent Document 1, since the power supply disconnecting circuit is provided between the power supply circuit and each circuit in the main body, the circuit configuration becomes complicated. Also, if there is an abnormality in the nurse call cordless handset, it will always be dropped.

  However, for example, if the patient is in good condition or the bed is not being used, the nurse call cordless handset may not be required. May be removed from the handset. In this case, there is a problem that if the nurse call cordless handset is removed, a drop-off call is applied.

  In addition, for a configuration in which a wall switch is provided with a changeover switch that can suspend notification of disconnection / breakage of the nurse call slave unit, a medical worker will notify the drop / breakage of the nurse call slave unit. Although it can be visually confirmed whether or not it is on hold, the following problems existed. When the nurse call cordless handset is reattached while the changeover switch is operated to notify the nurse call cord dropout / breakage, the medical staff, etc. operate the changeover switch to put the status on hold. It was troublesome to have to cancel. In addition, when a medical worker forgets to operate the changeover switch and the nurse call cordless handset is attached with the notification of disconnection or disconnection of the nurse call cord on hold, a drop-off call must be made Even so, dropping calls were put on hold and it was dangerous.

  The present invention has been made to solve such a problem. When a nurse call cordless handset such as a hand-type cordless handset is not required, a medical worker can hold a drop-off call and cancel the hold. The object is to enable easy switching while visually confirming.

  In order to solve the above-described problems, in the present invention, a nurse call cordless handset provided with a call operation unit for performing a call manipulation is detachably connected to an outlet, and the nurse call cordless handset falls off when the nurse call cord is dropped from the outlet. When a nurse call cordless handset is dropped from the outlet while the drop hold operation unit is operated, the drop call signal is put on hold and the drop call signal is put on hold at the outlet. When the nurse call cordless handset is connected, the suspension of the drop call signal transmission is canceled. At this time, the confirmation indicator light is displayed differently between when the drop call signal is sent and when the drop call signal is put on hold, and the time when the drop call signal is sent continuously. The drop-off notification is performed when the time becomes longer than a predetermined time.

  In other words, when the nurse call slave unit is removed from the outlet for attaching / detaching the nurse call slave unit provided in the wall-embedded slave unit, if the nurse call slave unit is removed while operating the drop-off holding unit, the drop-off notification is performed. I try not to. Further, when the nurse call slave is removed without operating the drop-off holding operation unit and a predetermined time elapses, drop-off notification is performed. Further, when the nurse call slave unit is reattached to the outlet in a state where the nurse call slave unit is removed while operating the drop hold operation unit, the hold of sending the drop call signal is released. Further, the display state of the confirmation indicator lamp is made different between when the drop call signal is sent and when the drop call signal is put on hold.

  According to the present invention configured as described above, when the nurse call cordless handset is dropped from the outlet while the drop hold operation unit is being operated, the sending of the drop call signal is put on hold. The nurse call handset can be removed from the wall-embedded handset without making a call. In this state, if the nurse call cordless handset is attached to the wall-embedded cordless handset, the suspension of the drop call signal transmission will be released, so the medical staff must cancel the suspension of the drop call signal transmission one by one. Disappears. Therefore, it is not forgotten to cancel the suspension of transmission of the drop call signal, and it is possible to prevent a dangerous state. In addition, since the display state of the confirmation indicator light is different between when the drop call signal is put on hold and when the drop call signal is sent, the medical worker can check whether the drop call has been held successfully. It is possible to easily switch between dropping call hold and dropping call hold cancellation while visually confirming the above.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram illustrating a configuration example of a nurse call system according to the present embodiment. FIG. 2 is a block diagram showing a configuration example of a nurse call slave device and a corridor lamp applied to the nurse call system according to the present embodiment.

  As shown in FIG. 1, the nurse call system according to the present embodiment includes a hospital room unit 1 installed in each hospital room and a nurse call parent device 2 installed in the nurse center and functioning as a center device. Here, the hospital room unit 1 and the nurse call parent device 2 are connected to each other via a communication line. Moreover, the hospital room unit 1 is installed in each hospital room.

  The nurse call system according to the present embodiment includes, as other standard components, for example, a handin squall main apparatus 3 installed in a communication center in a hospital, a private branch exchange (PBX) 4, a public A network 5 and a wireless unit 6 are provided.

  A wireless unit 6 is connected to the handheld squall main device 3. The PBX 4 is connected to the public network 5. The Handan Scall main device 3 is composed of, for example, an exchange device compatible with a local PHS (Personal Handy-phone System), and includes a plurality of extensions, a local line, and maintenance in addition to an internal control unit and a time switch. . Here, the radio base stations 7 and 8 of the radio unit 6 are connected to the extensions of the hand-in-hand call main device 3, respectively.

  The radio base stations 7 and 8 each form a radio area, and are connected to the mobile terminals 7a to 7n and 8a to 8n existing in the radio area via a radio line. A private branch exchange 4 is connected to the main line of the handicraft squall main unit 3. The portable terminals 7a to 7n and 8a to 8n are carried by medical workers such as doctors and nurses and caregivers.

  The hospital room unit 1 includes a hand-type handset for calling (corresponding to the nurse call handset in the claims) 9 and a wall-embedded handset 10 to which the hand-type handset 9 is detachably connected. I have. Here, the wall-embedded handset 10 is provided on a wall surface of a hospital bed or the like, and is connected to a corridor lamp 11.

  The hand-type slave unit 9 is a device that can communicate with the nurse call master unit 2, and as shown in FIG. 2, the call button 12, the speaker unit 13, the microphone unit 14, and the interface for the hand-type slave unit connected thereto. 15.

  The call button 12 is a button-like operation device that makes a call by an operation by the patient, and outputs a call signal when operated by the patient. The speaker unit 13 outputs the voice from the nurse call master unit 2 when the hand-type slave unit 9 and the nurse call master unit 2 are talking. The speaker unit 13 outputs sound from the nurse call parent device 2 when broadcast from the nurse call parent device 2. The microphone unit 14 inputs a voice uttered by the patient when the hand-type slave unit 9 and the nurse call master unit 2 are talking. The hand type slave unit interface 15 inputs and outputs the call signal and voice signal described above.

  The wall-embedded portable device 10 includes an outlet 16, an interface 17 for a wall-embedded child device, a confirmation indicator lamp 18, a recovery button (corresponding to the drop-off holding operation section in claims) 19, a recovery button on / off A detection unit 20 and a drop call signal output determination unit 21 are provided.

  The outlet 16 is for connecting the hand-type slave unit 9 to the wall-type slave unit 10, and a connector such as a plug provided at the end of the cord of the hand-type slave unit 9 is detachable from the outlet 16. Configured to connect to. The wall embedded type slave unit interface 17 inputs the call signal and voice signal output from the hand type slave unit 9 and outputs the voice signal input from the nurse call master unit 2 to the hand type slave unit 9. Further, the wall-mounted slave unit interface 17 detects whether or not the hand-type slave unit 9 is connected to the outlet 16 of the wall-embedded slave unit 10, and the result is a drop call signal output determination unit 21. Output to.

  The confirmation indicator lamp 18 has a light emitting portion exposed on the surface of the wall-mounted type slave unit 10, and changes the display (light emission) state according to the determination result by the drop call signal output determination unit 21. The recovery button 19 is an operation for restoring the original state when the call button 12 of the hand-type slave unit 9 is pressed by the patient and a call from the hand-type slave unit 9 to the nurse call base unit 2 is performed. Is to do. In addition, the recovery button 19 does not have a function that works when it is pressed alone except when a call is made, but the recovery button 19 according to the present embodiment is used when the hand-type slave unit 9 is removed. Pressed.

  The recovery button on / off detection unit 20 detects whether or not the recovery button 19 is pressed, and outputs the result to the drop call signal output determination unit 21.

  The drop call signal output determination unit 21 outputs the call signal and the voice signal input by the wall-embedded slave unit interface 21 to the nurse call master unit 2 and the voice signal input from the nurse call master unit 2 as a hand type. Output to the slave unit 9. Here, when the call button 12 of the hand-type slave unit 9 is operated, a call signal is output to the nurse call base unit 2 to be called. In response to this, the call state is released by pressing the recovery button 19 or a response operation by the nurse call parent device 2.

  Further, the drop call signal output determination unit 21 inputs the result of whether or not the recovery button 19 is pressed from the recovery button on / off detection unit 20. Further, the drop call signal output determination unit 21 inputs the result of whether or not the hand slave unit 9 is disconnected from the outlet 16 from the wall embedded slave unit interface 17. If it is determined from these results that the hand-type slave unit 9 has dropped from the outlet 16, and the recovery button 19 is not pressed, the drop call signal output determination unit 21 sends the drop call signal to the corridor lamp 11. Continue to send. At this time, the confirmation indicator lamp 18 is lit.

  On the other hand, if it is determined that the hand-held device 9 has dropped from the outlet 16, and the recovery button 19 is pressed, the drop call signal output determination unit 21 suspends sending the drop call signal. At this time, the confirmation indicator lamp 18 blinks a certain number of times (for example, three times) and then turns off.

  The corridor lamp 11 is a device that is interposed between the nurse call master unit 2 and the wall-embedded slave unit 10, and as shown in FIG. 2, a timer unit 22, a drop call signal output hold determination unit 23, A dropout notification unit 24 is provided.

  The timer unit 22 is for measuring the time during which the drop call signal is continuously sent out from the drop call signal output determination unit 21 of the wall-mounted slave unit 10. The drop call signal output hold determination unit 23 determines whether or not the time measured by the timer unit 22 is equal to or longer than a predetermined time (for example, 10 seconds). Is output to the dropout notification unit 24 and the nurse call master unit 2. The drop call signal output hold determination unit 23 may be configured to change the predetermined time described above.

  The drop-out notifying unit 24 is for notifying that the hand-type slave unit 9 has dropped from the outlet 16 of the wall-embedded slave unit 10, and the drop-off call signal is input from the drop-off call signal output hold determining unit 23. In this case, a warning sound is output or a warning light is turned on. Further, the drop call signal output from the drop call signal output hold determination unit 23 is input to the nurse call parent device 2, and the nurse call parent device 2 notifies the drop notification similarly to the drop notification unit 24.

  In the nurse call system according to the present embodiment configured as described above, a recovery button is used to remove the hand-type slave unit 9 from the outlet 16 of the wall-embedded slave unit 10 so that the medical staff does not notify the drop-off. It is necessary to remove the hand slave 9 while pressing 19. However, when the restoration button 19 is not sufficiently pressed, the confirmation indicator lamp 18 remains lit, and the drop call signal is output from the drop call signal output determination unit 21. At this time, a drop call signal is output from the drop call signal output determination unit 21. In the hallway lamp 11, the drop notification unit 24 and the nurse call are used unless the time measured by the timer unit 22 exceeds a predetermined time. In the base unit 2, the drop-out notification of the hand-type slave unit 9 is not performed.

  Accordingly, the medical worker visually recognizes that the confirmation indicator lamp 18 is still lit, grasps that the drop-off hold has not been successful, and puts the hand on the outlet 16 of the wall-embedded handset 10. Reattach the shaper 9 again. When the hand-type slave unit 9 is attached, the drop call signal output determination unit 21 finishes sending the drop call signal. Further, the confirmation indicator lamp 18 is turned off. Further, the drop call signal output hold determination unit 23 of the corridor lamp 11 sends the drop call signal to the drop notification unit 24 and the nurse call parent if the drop call signal sent from the drop call signal output determination unit 21 is not longer than a predetermined time. Does not output to machine 2. Therefore, if the medical worker can attach the hand-type slave unit 9 to the outlet 16 of the wall-embedded slave unit 10 within a predetermined time, the drop-out notification will not be performed.

  On the other hand, the medical worker can visually recognize that the confirmation indicator lamp 18 has flashed and can grasp that the drop-off has been successfully held.

  Next, the operation of the nurse call system according to the present embodiment, the drop hold switching method, and the drop hold release method will be described. FIG. 3 is a flowchart showing the operation of the nurse call system and the drop hold switching method according to the present embodiment.

  First, the interface 17 for wall-embedded slave units detects whether or not the hand-type slave unit 9 has been removed from the outlet 16 of the wall-embedded slave unit 10 (step S1). If removal of the hand slave 9 is not detected by the wall-embedded slave interface 21 (NO in step S1), the processing in step S1 is repeated. On the other hand, if the removal of the hand-type slave unit 9 is detected by the wall-embedded slave unit interface 21 (YES in step S1), whether or not the recovery button 19 is pressed is turned on / off. Detection is performed by the detection circuit 20 (step S2).

  When the recovery button 19 is not pressed, in other words, when the recovery button 19 is not pressed by the recovery button on / off detection circuit 20 (NO in step S2), the drop call signal output determination unit 21 Then, a drop call signal indicating that the hand slave 9 has dropped is sent, and the confirmation indicator lamp 18 is turned on (step S3). On the other hand, if the recovery button 19 is detected to have been pressed by the recovery button on / off detection circuit 20 (YES in step S2), the drop call signal output determination unit 21 suspends sending the drop call signal. Then, the confirmation indicator lamp 18 blinks a certain number of times (step S4).

  When the drop call signal output determination unit 21 sends a drop call signal in step S3, the drop call signal output hold determination unit 23 of the corridor lamp 11 receives the drop call signal and drops from the drop call signal output determination unit 21. It is checked whether or not the calling signal has been transmitted for a predetermined time or more (step S5). If the dropped call signal output hold determination unit 23 determines that the dropped call signal has not been transmitted from the dropped call signal output determination unit 21 for a predetermined time or longer (NO in step S5), the process proceeds to step S6. On the other hand, if the drop call signal output hold determination unit 23 determines that the drop call signal has been sent from the drop call signal output determination unit 21 for a predetermined time or more (YES in step S5), the drop notification unit 24 The dropout is notified (step S7).

  If the drop call signal output determination unit 21 has suspended sending the drop call signal in step S4, or if the drop call signal has not been sent from the drop call signal output determination unit 21 for a predetermined time or more in step S5, the drop call is made. When the signal output hold determination unit 23 makes a determination, the drop call signal output hold determination unit 23 does not output the drop call signal to the drop notification unit 24 and the nurse call parent device 2, and has suspended the drop notification. (Step S6).

  As described above in detail, according to the present embodiment, the hand-type slave unit 9 having the call button 12 is detachably connected to the outlet 16 of the wall-embedded slave unit 10, and the hand-type slave unit is connected from the outlet 16 to the hand-type slave unit. When 9 is dropped, the drop call signal output determination unit 21 sends a drop call signal, but when the handset 9 is dropped while the recovery button 19 is operated, the drop call signal output determination unit 21 Suspends sending out the drop call signal. Further, when the handset 9 is connected to the outlet 16 in a state where the sending of the drop call signal is suspended, the drop call signal output determination unit 21 cancels the suspension of sending the drop call signal. I have to. At this time, the display of the confirmation indicator lamp 18 is different between when the drop call signal is sent and when the drop call signal is put on hold, and the drop call signal output determination unit 21 drops the call. When the signal is continuously sent out for a predetermined time or more, the drop notification unit 24 of the hallway lamp 11 and the nurse call master unit 2 perform the drop notification.

  Accordingly, when the handset 9 is dropped from the outlet 16 while the recovery button 19 is being operated, the dropout call signal output from the dropout call signal output determination unit 21 is suspended, so that the medical worker The hand slave unit 9 can be detached from the wall-embedded slave unit 10 without making a drop call. In this state, if the hand-type slave unit 9 is attached to the outlet 16 of the wall-embedded slave unit 10, the suspension of the drop-out call signal from the drop-out call signal output determination unit 21 is released, so The user does not need to cancel the suspension of the sending of the drop call signal. Therefore, it is not forgotten to cancel the suspension of transmission of the drop call signal, and it is possible to prevent a dangerous state.

  Further, since the display state of the confirmation indicator lamp 18 is different between when the drop call signal is put on hold and when the drop call signal is sent, the medical worker can check whether or not the drop call hold is successful. It is possible to easily switch between dropping call drop hold and drop call hold release while visually confirming the above.

  In this embodiment, the hand-type slave unit 9 is connected to the outlet 16 of the wall-embedded slave unit 10, but the present invention is not limited to this. For example, the outlet 16 of the wall-embedded portable device 10 may be detachably connected with a grip push button that does not have a call function and is provided only with an operation unit that performs a call operation.

  Moreover, in this embodiment, although the timer part 22 and the drop call signal output holding | maintenance determination part 23 are provided in the corridor lamp 11, it is not limited to this. For example, the timer unit 22 and the drop call signal output hold determination unit 23 may be provided in the wall-embedded child device 10 or in the nurse call parent device 2.

  In the present embodiment, whether or not the drop call is successfully held is distinguished by changing the display state of the confirmation indicator lamp 18, but the present invention is not limited to this. For example, a confirmation alarm generation unit may be provided instead of the confirmation indicator lamp 18, and the alarm sound generated by the confirmation alarm generation unit may be made different so as to distinguish whether or not the dropped call has been successfully held.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.

It is a schematic block diagram of the nurse call system by this embodiment. It is a block diagram which shows the structural example of the nurse call cordless handset applied to the nurse call system by this embodiment, and a corridor lamp. It is a flowchart which shows the operation | movement of the nurse call system by this embodiment, and the drop-off hold switching method.
