  When the master CPU 110 of the master device 11 detects the first master device control signal from the control device 15 (the control device CPU 150), the master CPU 110 stops the call notification operation and The above-mentioned patient / response number association information added to the machine control signal can be stored in the parent machine memory 111.

  As is apparent from the above description, at least one of the base unit memory 111 of the base unit 11 and the control unit memory 151 of the control unit 15 stores the patient in the wireless terminal 12a as patient / response count association information. The number of responses to the call from is the patient ID of the patient in the bed where the nurse call cordless handset 1a is installed in the “room A” for each work band such as day shift, night shift (including quasi-night shift). As the association is stored, the number of responses to the call from the patient in the wireless terminal 12b is also associated with the patient ID of each patient for each work band such as a day shift, night shift (including quasi-night shift). Can be memorized.

  In addition, as the above-mentioned patient / response number association information, the number of responses to calls from each patient in the wireless terminals 12a, 12b is each patient for each work band such as day shift, night shift (including quasi-night shift). In the case where it is stored in advance in at least one of the parent device memory 111 of the parent device 11 and the control device memory 151 of the control device 15 in association with the patient ID of the parent device 11, first, only in the parent device memory 111 of the parent device 11 If the nurse in the room (in the nurse station) performs a predetermined information requesting operation using the parent device display unit 113 and the parent device operation unit 114 in the case where the information is stored in advance, this operation is performed. The detected base unit CPU 110 relates to the patient / response count association information read from the base unit memory 111, that is, for each work band such as a day shift, night shift (including quasi-night shift). Attached let the wireless terminal 12a, the number of responses to calls from each patient at 12b can be displayed on the base unit display unit 113.

  On the other hand, when the above-mentioned patient / response count association information is stored in advance only in the control device memory 151 of the control device 15, the resident nurse (in the room in the nurse station) sends a call to the master unit operation unit 114. When a predetermined information requesting operation is performed, the master CPU 110 that has detected this operation controls a control signal for reading patient / response count association information from the control device memory 151 of the control device 15 (hereinafter, for the first control device). A read control signal). The first control device read control signal is transmitted to the control device CPU 150 of the control device 15 via a path opposite to the first parent device call notification signal.

The second call response signal is transmitted to the control device CPU 150 of the control device 15 via a path reverse to the second wireless terminal call notification signal.

  When the control device CPU 150 of the control device 15 detects the second call response signal from the wireless terminal 12b, the number of responses to the call from the patient in the wireless terminal 12b includes a day shift band and a night shift band (including a semi-night shift band). ) Or the like, and is associated with the patient ID of the patient in the hospital bed where the nurse call cordless handset 1a is installed in the “room A” and stored in the control device memory 151 in advance as new patient / response number association information. Rewrite the patient / response count association information.

  The control device CPU 150 of the control device 15 that has detected the second call response signal from the wireless terminal 12b forms a communication path between the corridor lamp side control device I / F 152 and the exchange side control device I / F 154. The first corridor lamp control signal similar to the first operation described above, the control data for stopping the call notification operation performed in the master unit 11, and the control device memory 151 are rewritten and stored. A control signal (hereinafter referred to as a second master unit control signal) to which the above-mentioned patient / response number association information is added is generated. Of these first corridor lamp control signal and second master unit control signal, the first corridor lamp control signal is transmitted from the controller CPU 150 via the corridor lamp side controller I / F 152 and the corridor lamp line L10. Are transmitted to all the corridor lights 10a, 10b and 10c. On the other hand, the second base unit control signal is transmitted to base unit CPU 110 of base unit 11 through the same route as the first base unit control signal.

  All the corridor lamps 10a, 10b, and 10c collate the corridor lamp ID added to the first corridor lamp control signal from the control device 15 (the control device CPU 150) with the corridor lamp ID of the own corridor lamp. To do. Here, only the corridor lamp 10a has the same corridor lamp ID, and the call function (not described in detail) of the nurse call cordless handset 1a that is the caller connected to the cordless handset line L1a and the call between the corridor lamp line L10. By forming a path, the call function (not detailed) of the nurse call cordless handset 1a used by the calling patient, the cordless handset line L1a, the corridor lamp 10a, the corridor lamp line L10, and the corridor lamp of the control device 15 Side control device I / F 152, control device CPU 150, switch side control device I / F 154, switch line L12, switch 14, base station line L13, base station 13, and call function of wireless terminal 12b used by patrol nurse of response destination A call path between the call (not detailed) and the call can be established.

  In addition, when the master unit CPU 110 of the master unit 11 detects the second master unit control signal from the control device 15 (the control unit CPU 150), the master unit CPU 110 stops the call notification operation and The above-mentioned patient / response number association information added (newly rewritten) to the machine control signal can be stored in the parent device memory 111, and the patient / response number association information can be rewritten.

  As is clear from the above explanation, the visiting nurses who are assigned to the same patient who has made multiple calls from the same patient, in this case, two toilet assistance calls from the nurse call handset 1a. When the visiting nurse carrying the wireless terminal 12a has already responded to the first call, the visiting nurse who is in charge of notifying the second calling carries the wireless terminal 12b. As nurses, the visiting nurses can be assigned so that the number of calls of the patients they handle is uniform.

  Further, in the case where the visiting nurse in charge of the same patient who has made two toilet assistance calls from the nurse call cordless handset 1a is allocated as described above, for example, the nurse call child in the “room C” When a patient on the bed where the machine 1c is installed activates a call function (not described in detail) for making a normal nurse call, the call is connected to the caller's nurse call slave 1c via the slave line L1c. In the corridor lamp 10c, a call signal (hereinafter referred to as a second call signal) to which the slave unit ID of the nurse call slave unit 1c, the corridor lamp ID of the own corridor lamp, and call type data indicating a normal nurse call call are added. .) Is generated. The second call signal is transmitted from the hall light 10c through the hall light line L10 (except for the hall light 10c), and from the hall light 10c to the hall light line L10 and the hall light of the control device 15. Is transmitted to the control device CPU 150 via the side control device I / F 152.

  In other corridor lamps 10a and 10b (except for corridor lamp 10c), since the transmitted second call signal is not an output signal from control device 15 (control device CPU 150), the second call signal is usually It is determined that the ringing signal is invalid.

  The control device CPU 150 of the control device 15 has a nurse call handset in the “room C” based on the corridor lamp ID, handset ID and call type data added to the second call signal from the corridor lamp 10c. It is detected that a normal nurse call has been called by the patient in the hospital bed where 1c is installed, and the room number of "C. Room C" stored in advance in the control device memory 151 in association with the corridor lamp ID is added as well. The terminal ID of the wireless terminal to be called and notified with the patient ID of the patient who is the call source stored in advance in the control device memory 151 in association with the assigned child device ID, here set as the same group (detailed) Of the terminal IDs of the wireless terminals 12a and 12b previously associated with the group IDs of the nurse call slaves 1a, 1b, and 1c. Two toilets assistance call to the wireless terminal 12a from, since 12b has already acknowledged once, for example, reads out the terminal ID of the wireless terminal 12a, 12b. Further, the control device CPU 150 adds a call notification signal (hereinafter referred to as second master device call notification) to which the room number read from the control device memory 151, the slave device ID of the nurse call slave device 1c, and the call type data are added. And is output to the parent device 110 of the parent device 11 through the same route as the first call signal described above, and the patient ID and wireless of the patient who is read out in the same manner A call notification signal (hereinafter referred to as a third wireless terminal call notification signal) to which the terminal IDs and call type data of the terminals 12a and 12b are added is generated, and the first (second) wireless terminal is used. Are output to all the radio terminals 12a, 12b,... Via the same route as the call notification signal.

  Based on the room number, the slave unit ID, and the call type data added to the second master unit call notification signal from the control unit 15 (the control unit CPU 150), the base unit CPU 110 of the base unit 11 In room C, it is detected that a normal nurse call has been called by the patient in the bed where the nurse call cordless handset 1c is installed, and a notification (sound emission, display) to that effect is sent to the parent machine call calling unit 112 and the parent call It is performed using the machine display unit 113 (not described in detail), and the child machine ID of the nurse call child machine 1c that is the calling source is stored in the parent machine memory 111.

  All of the wireless terminals 12a, 12b,...

To do. Here, only the corridor lamp 10c has the same corridor lamp ID, and the call function (not described in detail) of the nurse call cordless handset 1c that is the caller connected to the cordless handset line L1c and the call between the corridor lamp line L10. By forming a path, the call function (not detailed) of the nurse call slave unit 1c used by the calling patient, the slave unit line L1c, the corridor lamp 10c, the corridor lamp line L10, and the corridor lamp of the control device 15 Side control device I / F 152, control device CPU 150, switch side control device I / F 154, switch line L12, switch 14, base station line L13, base station 13, and call function of wireless terminal 12a used by patrol nurse of response destination A call path between the call (not detailed) and the call can be established.

  Further, when the master unit CPU 110 of the master unit 11 detects the third master unit control signal from the control unit 15 (the control unit CPU 150), the master unit CPU 110 stops the operation for calling notification and the third master unit The above-mentioned patient / response number association information added (newly rewritten) to the machine control signal can be stored in the parent device memory 111, and the patient / response number association information can be rewritten.

  As is clear from the above description, in the case where the visiting nurse in charge for the same patient who has made two toilet assistance calls with the nurse call cordless handset 1a is allocated as described above, other patients When there is a different call depending on the call type from the nurse, here, when there is a normal nurse call from the nurse call handset 1c, the radio terminals 12a and 12b are carried as the visiting nurses in charge of informing the call, respectively. In addition to assigning each visiting nurse, a normal nurse call call from the nurse call cordless handset 1c is called and notified by one of the radio terminals 12a and 12b, and the patient who is responsible for the call is notified. Calls from each patient are alternately notified to the wireless terminals 12a and 12b so that the number of calls is uniform for each visiting nurse. It is also possible.

  Next, a third operation according to the embodiment of the present invention will be described.

  As is clear from the first and second operations described above, the number of patients / responses stored in advance in at least one of the parent device memory 111 of the parent device 11 and the control device memory 151 of the control device 15. As the number of responses to the call from each patient in the wireless terminals 12a and 12b associated with each past work band such as day shift band, night shift band (including quasi-night shift band), etc., for example, “A The number of calls from the patient on the bed where the nurse call cordless handset 1a is installed in the “room” is “2”, and the number of calls from the patient on the bed where the nurse call cordless handset 1b is installed in the “room B” is “ “6 times”, the number of calls from the patient in the bed where the nurse call cordless handset 1c is installed in “Room C” is “8 times”, the wireless terminal 12a responds to these calls 10 times, and the wireless terminal By displaying information indicating that 12b has responded 6 times (hereinafter referred to as nurse response frequency information) on the parent device display unit 113 (of the parent device 11), a plurality of wireless terminals 12a, 12b,.・ ・ Among the nurses who are able to grasp the response ability (calling ability) of each visiting nurse carrying the wireless terminals 12a and 12b, The ratio of calls that can be handled in one work period for each teacher can be set in advance using the parent device display unit and the parent device operation unit 114. Here, the rate at which a traveling nurse carrying the radio terminal 12a can answer a call from the nurse call slaves 1a, 1b, 1c set as the same group (not described in detail) at one time. “60%” can be set as “40%” as the rate at which a visiting nurse carrying the wireless terminal 12b can answer a call from similar nurse call slaves 1a, 1b, 1c at the same time. The set information (hereinafter referred to as nurse response rate information) is stored in the base unit memory 111 under the control of the base unit CPU 110.

  The above-mentioned nurse response ratio information stored in advance in the base unit memory 111 of the base unit 11 is read from the base unit memory 111 under the control of the base unit CPU 110, and then the base unit I / F 115, the base unit line. L11 is transmitted to the control device CPU 150 via the parent device side control device I / F 153 of the control device 15, and can be stored in the control device memory 151 under the control of the control device CPU 150.

  The above-mentioned nurse response ratio information, patient / nurse association information, and nurse response count information are stored in advance in at least one of the base unit memory 111 of the base unit 11 and the control unit memory 151 of the control unit 15. For example, in the “B room”, a patient in the hospital bed where the nurse call cordless handset 1b is installed activates a calling function (not described in detail) for notifying a deficiency or termination related to administration of an infusion or the like. Then, in the corridor lamp 10b connected to the caller's nurse call slave unit 1b via the slave unit line L1b, administration of the slave unit ID of the nurse call slave unit 1b, the corridor lamp ID of the own corridor lamp, infusion, etc. A paging signal (hereinafter referred to as a third paging signal) to which paging type data for notifying the malfunction or the end of the paging is added is generated. The third call signal is transmitted from the hall light 10b through the hall light line L10 (excluding the hall light 10b) to the other hall lights 10a and 10c, from the hall light 10b to the hall light line L10, and the hall light of the control device 15. Is transmitted to the control device CPU 150 via the side control device I / F 152.

  In other corridor lamps 10a and 10c (except for corridor lamp 10b), since the transmitted third call signal is not an output signal from control device 15 (control device CPU 150), the third call signal is usually It is determined that the ringing signal is invalid.

  The control device CPU 150 of the control device 15 has a nurse call handset in the “room B” based on the corridor light ID, handset ID and call type data added to the third call signal from the corridor light 10b. It is detected that the patient in the hospital bed where 1b is installed has made a call for notifying the inconvenience or the end of administration of infusion or the like, and is associated with the corridor lamp ID and stored in the control device memory 151 in advance. ”And the terminal ID of the wireless terminal to be notified of the call with the patient ID of the patient who is the call source stored in the control device memory 151 in advance in association with the room number of“ Of the nurse call cordless handsets 1a, 1b, and 1c set as a group (not described in detail) and carrying the radio terminal 12a in a single work band Refer to the nurse response rate information that the rate that the guardian can respond is “60%” and the rate that the traveling nurse carrying the wireless terminal 12b can respond is “40%”. A call to notify the malfunction or termination related to administration of infusion or the like from the nurse call slave unit 1b, which is the first (first) call from the nurse call slave units 1a, 1b, 1c that have been set (not detailed) The terminal ID of the wireless terminal 12a to be notified of the call preferentially is read out. Further, the control device CPU 150 sends a call notification signal for a parent device (hereinafter referred to as a third parent device) to which the room number read from the control device memory 151, the child device ID of the nurse call child device 1b, and the call type data are added. And a call notification signal (hereinafter referred to as a fourth call notification signal) to which the patient ID of the patient who is the read source, the terminal ID of the wireless terminal 12a, and the call type data are added in the same manner. This is referred to as a radio terminal call notification signal). Of these third parent device call notification signals and fourth wireless terminal call notification signals, the third parent device call notification signal is the first (second) parent device call notification signal. The data is transmitted to the parent CPU 110 of the parent device 11 through a similar route. On the other hand, the fourth wireless terminal call notification signal is also transmitted to all the wireless terminals 12a, 12b,... Via the same route as the first (second, third) wireless terminal call notification signal. Respectively transmitted to.

  Based on the room number, the slave unit ID, and the call type data added to the third master unit call notification signal from the control unit 15 (the control unit CPU 150), the base unit CPU 110 of the base unit 11 In room B, detect that there is a call for notifying the end of a drip infusion or the like by a patient in the bed where nurse call cordless handset 1b is installed, and notify (sound, display) to that effect The call is performed using the parent device call communication unit 112 and the parent device display unit 113 (not described in detail), and the child device ID of the nurse call child device 1b that is the calling source is stored in the parent device memory 111.

  All of the wireless terminals 12a, 12b,... Are among the patient ID, terminal ID, and call type data added to the fourth wireless terminal call notification signal from the control device 15 (the control device CPU 150). The terminal ID is compared with the terminal ID of the own wireless terminal, and only when the terminal ID matches, there is a problem related to administration of infusion or the like by the patient in the bed where the nurse call cordless handset 1b is installed in the “room B”. It is detected that there is a call for notifying the end, and a notification to that effect (sound emission, display) is made (not detailed). Here, only the wireless terminal 12a has the same terminal ID, and the call notification described above is performed.

  The nurse who performed the response operation first among the in-room nurses (in the nurse station) and the traveling nurses carrying the wireless terminal 12a, which confirmed the above call notification, When the traveling nurse carrying the preferentially called radio terminal 12a performs a predetermined response operation on the own radio terminal, the call function (not detailed) of the radio terminal 12a is only activated. Instead, a first call response signal similar to the first and second operations described above with the terminal ID of the own wireless terminal added is generated and transmitted to the control device CPU 150 of the control device 15.

  When the control device CPU 150 of the control device 15 detects the first call response signal from the wireless terminal 12a, the number of responses to the call from the patient in the wireless terminal 12a includes a day shift band and a night shift band (including a semi-night shift band). ) Or the like, and is associated with the patient ID of the patient in the bed where the nurse call cordless handset 1b is installed in the “B room”, and is stored in advance in the control device memory 151 as new patient / response number association information. Rewrite the patient / response count association information.

  The control device CPU 150 of the control device 15 that has detected the first call response signal from the wireless terminal 12a forms a communication path between the corridor lamp side control device I / F 152 and the exchange side control device I / F 154. As a control signal for forming a communication path between the call function (not described in detail) of the nurse call slave unit 1b that is a caller connected to the slave unit line L1b and the corridor lamp line L10, the corridor lamp 10b A control signal to which the corridor lamp ID is added (hereinafter referred to as a third corridor lamp control signal), control data for stopping the call notification operation performed in the master unit 11, and the control device memory 151 A control signal (hereinafter referred to as a fourth master unit control signal) to which the above-mentioned patient / response number association information rewritten and stored is added is generated. Of these third corridor lamp control signal and fourth master unit control signal, the third corridor lamp control signal passes through the same path as the first and second corridor lamp control signals. Are transmitted to all the corridor lights 10a, 10b and 10c. On the other hand, the fourth base unit control signal is also transmitted to the base unit CPU 110 of the base unit 11 through the same route as the first (second, third) base unit control signal.

  All the corridor lamps 10a, 10b, and 10c collate the corridor lamp ID added to the third corridor lamp control signal from the control device 15 (the control device CPU 150) with the corridor lamp ID of the own corridor lamp. To do. Here, only the corridor lamp 10b has the same corridor lamp ID, and the call function (not detailed) of the nurse call cordless handset 1b connected to the cordless handset line L1b and the call between the corridor lamp line L10. By forming a path, the call function (not detailed) of the nurse call cordless handset 1b used by the calling patient, the cordless handset line L1b, the corridor lamp 10b, the corridor lamp line L10, and the corridor lamp of the control device 15 Side control device I / F 152, control device CPU 150, switch side control device I / F 154, switch line L12, switch 14, base station line L13, base station 13, and call function of wireless terminal 12a used by patrol nurse of response destination A call path between the call (not detailed) and the call can be established.

  In addition, when the master unit CPU 110 of the master unit 11 detects the fourth master unit control signal from the control device 15 (the control unit CPU 150), the master unit CPU 110 stops the operation for calling notification and the fourth master unit The above-mentioned patient / response number association information added (newly rewritten) to the machine control signal can be stored in the parent device memory 111, and the patient / response number association information can be rewritten.

  As is apparent from the above description, a call from nurse call slaves 1a, 1b, 1c set as the same group (not described in detail) is carried around the radio terminal 12a in a single work zone. The rate at which nurses can respond is “60%”, and the rate at which visiting nurses carrying the wireless terminal 12b in the same work call can make calls from similar nurse call slaves 1a, 1b, 1c is “4”. When the nurse response rate information indicating “wari” is stored in at least one of the parent device memory 111 of the parent device 11 and the control device memory 151 of the control device 15 (of the control device) The control device CPU 150 is the first call (first time) of the nurse call slaves 1a, 1b, 1c set (not described in detail) as the same group. The terminal ID of the wireless terminal 12a is read out from the control device memory 151 as the terminal ID of the wireless terminal for notifying the trouble for the administration of infusion or the like from the slave unit 1b and the call for notifying the end, and the wireless terminal 12 is read out. You can call the traveling nurses you carry with priority.

  Next, among calls that differ for each call type from the nurse call slaves 1a, 1b, and 1c set as the same group (not detailed), the call was made after the first (first) call described above. For example, when different calls are made in the nurse call slave units 1a, 1b, and 1c for each of the second to fifth call types, here, the second call is performed in the nurse call slave unit 1c. Normal call for nurse call handset 1a as call for assistance, third call for nurse call handset 1b for nurse call handset 1b, fourth call for call to nurse call handset 1c as call for the fifth time When a call is made to notify you of a malfunction related to the administration of an intravenous drip or the end of the call, the nurse call is the second call. The control device CPU 150 that has detected the toilet assistance call from the machine 1c reads out, for example, the terminal ID of the wireless terminal 12b from the control device memory 151 among the terminal IDs of the wireless terminals 12a and 12b, and carries the wireless terminal 12b. The visiting nurses can be preferentially called. In addition, the control device CPU 150 that has detected a normal nurse call call from the nurse call slave device 1a, which is the third call, controls, for example, the terminal ID of the wireless terminal 12a among the terminal IDs of the wireless terminals 12a and 12b. Reading out from the device memory 151, the visiting nurse carrying the wireless terminal 12a can be preferentially called. In addition, the control device CPU 150 that has detected a normal nurse call call from the nurse call handset 1b, which is the fourth call, controls, for example, the terminal ID of the wireless terminal 12b among the terminal IDs of the wireless terminals 12a and 12b. It is possible to read out from the device memory 151 and call the visiting nurse carrying the wireless terminal 12b with priority. Furthermore, the control device CPU 150 that has detected a call for notifying a malfunction or administration related to administration of an infusion or the like from the nurse call cordless handset 1c, which is the fifth call, of the terminal IDs of the wireless terminals 12a and 12b, for example, The control device CPU 150 is set as the same group so that the terminal ID of the wireless terminal 12a can be read from the control device memory 151 and the visiting nurse carrying the wireless terminal 12a can be preferentially called (detailed). No.) “60%”, which is the rate at which a visiting nurse carrying the wireless terminal 12a can answer a call from the nurse call slaves 1a, 1b, 1c in a single work zone, and a similar nurse call child A call that can be answered by a traveling nurse who is carrying the wireless terminal 12b in a single work zone when calling from the machines 1a, 1b, and 1c. Referring to the “40%” patient teacher response rate information, the control device memory 151 is configured so that the rate becomes the wireless terminal 12a: 12b = 3: 2 as the wireless terminal for notifying the second and subsequent calls. The reading of the terminal ID from can be controlled.

  According to the first to third operations in the embodiment of the present invention, priority is given to a different call for each call type from the nurse call slaves 1a, 1b, and 1c set (detailed) in the same group. In order to notify the traveling nurse, the control device CPU 150 of the control device 15 causes the specific one wireless terminal to make a call notification as the terminal ID read from the control device memory 151 so that the response frequency becomes constant. However, the same effect can be obtained by delaying the call start time for the second and subsequent units. In this case, even if the first wireless terminal runs out of battery and cannot be notified of the call, the second and subsequent wireless terminals can be notified of the call. Can perform nursing work.

  Further, according to the first to third operations in the embodiment of the present invention, priority is given to a different call for each call type from the nurse call slave units 1a, 1b, and 1c set (detailed) in the same group. Among the wireless terminals 12 a, 12 b,..., The terminal ID of the wireless terminal that is the call destination is controlled by the control device CPU 150 of the control device 15. The case where the control device CPU 150 generates the wireless terminal call notification signal read from the memory 151 and added with the read terminal ID has been described. The terminal ID of the wireless terminal can be read from the base unit memory 111 under the control of the control unit CPU 150 of the control unit 15 or the base unit CPU 110 of the base unit 11. It can, for this read the call informing signal for wireless terminal obtained by adding a terminal ID, or may be generated by the master unit CPU110 not control CPU150 only.
