Description

  The present invention relates to a nurse call system that calls a medical worker such as a doctor or a nurse in response to a request from a patient in a hospital or the like.

  Conventionally, nurse call systems are used in hospitals and the like. The nurse call system wired a nurse call cordless handset installed in the vicinity of a patient in a patient room (for example, on a bed) and a nurse call parent set installed in a room for a medical worker (for example, a staff room). It is configured to be connected by such as. The nurse call slave unit and the nurse call master unit are connected via a corridor lamp, a control unit, and the like. Furthermore, a plurality of portable communication terminals (for example, PHS (Personal Handyphone System), cordless telephone, etc.) carried by a medical worker are connected to the nurse call parent device via radio. When the nurse call cordless handset is operated by the patient, the nurse call master phone or the mobile communication terminal operates a notification unit provided in the own device to output a ringing tone from a speaker, or to a display display. Calls are displayed, for example, to notify the call. The medical staff grasps the call from the patient by listening to the ringing tone or looking at the call display. A medical worker who has grasped the call can respond to the call with a handset or a portable communication terminal provided in the nurse call parent device.

  By the way, the medical staff judges the recovery condition of the patient's physical condition from the result of the examination conducted on the patient, the result of the examination conducted on the patient, and the like. In addition, medical workers often determine how well a patient is recovering based on past work experience. For this reason, medical workers who have little work experience may not be able to properly determine the recovery of the patient's physical condition.

  Therefore, a health condition monitoring system that automatically determines the condition of the physical condition of a monitoring subject such as an elderly person is known (for example, Patent Document 1). In the health condition monitoring system described in Patent Document 1, a sensor such as a pressure sensor or an infrared human sensor is attached to a living device such as an air mattress or a wheelchair used by the person being monitored, The number of physical movements of the monitoring subject is calculated as an activity amount, and the physical condition of the monitoring subject is determined from the calculated activity amount. Thereby, the relative of a monitoring subject can grasp | ascertain the recovery condition of a monitoring subject's physical condition from a determination result.

  In order to monitor a patient's health condition by attaching a sensor such as a pressure sensor or an infrared human sensor, which is a component of the health condition monitoring system described in Patent Document 1, to a medical device such as a bed or a wheelchair used by an inpatient. It can be used as a monitoring system. In that case, the number of movements of the patient is calculated as the amount of activity from the detection result of the sensor attached to the medical device, and the condition of the patient's physical condition is determined from the calculated amount of activity. The medical staff can grasp the recovery condition of the patient's physical condition based on the determination result.

  However, in such a monitoring system, since the condition of the patient's physical condition is determined based on the number of body movements of the patient, the patient's symptoms and sensors that are not related to the number of body movements cannot be detected. Recovery of the patient's physical condition (for example, symptoms of pain in the affected area) such as external or internal symptoms such as the presence or absence of pain in the affected area or mental conditions such as improvement or decrease in motivation to go out There is a problem that it is impossible to determine the recovery of physical condition that the pain of the affected area has been relieved or the recovery of physical condition that the motivation to go out has improved for the symptom of decreased motivation to go out) . Therefore, even if the medical staff grasps the physical condition of the patient using such a monitoring system, the patient's symptom that can determine the recovery condition of the patient's physical condition There has been a problem that it is limited to events that can be detected by the sensor.

JP 2004-174168 A

  The present invention has been made to solve such problems, and is not limited to events related to the number of body movements or events that can be detected by a sensor. The purpose is to make it possible to easily and appropriately judge the degree of recovery.

  In order to solve the above-described problems, in the nurse call system according to the present invention, a call type suitable for a symptom of the patient is set in the specific call operation unit of the nurse call slave used by the patient, and the patient calls the specific call operation unit. When the is operated, it is stored as a history. Then, the operation frequency of the specific call operation unit is totaled from the stored history, and the change in the physical condition of the patient who operated the specific call operation unit is determined from the total operation frequency.

  According to the present invention configured as described above, when the call type set in the specific call operation unit indicates a tendency to worsen the symptoms of the patient, if the operation frequency of the specific call operation unit increases, the patient Is determined to have deteriorated. On the other hand, when the call type set in the specific call operation unit indicates a recovery tendency of the patient's symptoms, it is determined that the patient's physical condition is recovered if the operation frequency of the specific call operation unit is increased. The In addition, when the call type set in the specific call operation unit indicates a tendency of deterioration of the patient's symptoms, it is determined that the patient's physical condition is recovered if the operation frequency of the specific call operation unit is decreased. The On the other hand, when the call type set in the specific call operation unit indicates a recovery tendency of the patient's symptoms, it is determined that the patient's physical condition is deteriorated when the operation frequency of the specific call operation unit is decreased. The Thereby, the medical staff can grasp | ascertain the recovery | restoration state of the physical condition of the patient who operated the specific calling operation part from the determination result. Therefore, the medical staff can easily and appropriately determine the recovery of the patient's physical condition without being limited to events related to the number of body movements and events that can be detected by a sensor.

Here, the nurse call slave unit 1 is connected to the nurse call master unit 10 via a transmission line. The nurse call handset 1 is pre-assigned handset identification information (for example, handset number) for identifying its own device. In addition, after the patient calls the medical staff by operating the nurse call slave unit 1, the nurse call slave unit 1 that has performed the call operation is in a state where the call operation cannot be performed. In this state, when a response to the call operation is made at the nurse call parent device 10 or a portable communication terminal carried by a medical worker (for example, PHS, not shown), the nurse call child device 1 is called. A recovery signal for returning to a state in which the call can be made is output from the nurse call parent device 10. The nurse call handset 1 that has received the recovery signal output from the nurse call base unit 10 returns to a state in which a call operation can be performed.

  The nurse call master unit 10 is installed in a room where a medical worker is present (for example, a staff room), and is used to notify a medical worker of a call from a patient and to respond to the medical worker. It is. Here, a plurality of nurse call slave devices 1 are connected to the nurse call master device 10. Further, between the nurse call master unit 10 and the nurse call slave unit 1, a control unit and a corridor lamp (not shown) are installed. The controller performs control related to a call and data transmission / reception between the nurse call slave unit 1 and the nurse call parent unit 10. The corridor lamp turns on or blinks an indicator lamp provided in its own device to notify the call by the nurse call slave unit 1.

  The control unit 11 controls each component of the nurse call parent device 10 as described later. The I / F unit 12 is connected to the child device I / F unit 5 in order for the nurse call parent device 10 to communicate with the nurse call child device 1. Further, the I / F unit 12 receives the normal call signal and the specific call signal output from the nurse call slave unit 1. Further, the I / F unit 12 outputs a restoration signal to the nurse call slave unit 1.

  The notification unit 13 includes a speaker, a display display, an indicator lamp, and the like. The alarm unit 13 outputs a ringing tone from the speaker, displays a call on the display display, or turns on or blinks the indicator lamp. The call slave unit 1 is notified that a call operation has been performed. Note that the notification unit 13 distinguishes between a normal call and a specific call by differentiating at least one of a ringing tone or voice output pattern, a display pattern by a display display, and a blinking pattern by an indicator lamp. good. Thereby, the medical worker who receives the call can grasp whether the notification is based on a normal call or a specific call.

  When the notification unit 13 is informing by a call operation performed by the nurse call handset 1, the nurse call handset 1 that has performed the call operation is in a state where the call operation cannot be performed. Therefore, a recovery operation unit (not shown) is provided in the nurse call parent machine 10. By the operation of the recovery operation unit, the control unit 11 generates a recovery signal and stops the notification of the notification unit 13.

  The memory | storage part 14 is comprised with memory | storage devices, such as memory, and the subunit | mobile_unit identification for identifying the history information which shows the log | history which the patient operated the specific call operation part 4, and the nurse call subunit | mobile_unit 1 which the patient used. Information is stored in association with each other. Further, the storage unit 14 includes the slave unit identification information, the call type information indicating the call type of the specific call operation unit 4 provided in the nurse call slave unit 1 specified by the slave unit identification information, and the nurse call slave unit 1 When the symptom of the patient who uses is recovered, the trend information indicating whether the operation frequency of the specific call operation unit 4 is increasing or decreasing is stored in association with each other. Here, the storage unit 14 stores a call type that matches the patient's symptoms.

  As shown in FIG. 2A, the storage unit 14 includes a handset number area 141 that stores handset identification information such as handset number indicating the nurse call handset 1 used by the patient, and the nurse call handset 1. The call type area 142 for storing call type information indicating the call type of the specific call operation unit 4 provided in the above, the operation frequency of the specific call operation unit 4 is increasing or decreasing when the patient's symptoms are recovered A trend area 143 for storing trend information indicating whether the trend is present is stored. In the handset number area 141, information such as “001” is stored as handset identification information. In the call type area 142, information such as “the affected part is painful” is stored as the call type information. The trend area 143 stores information such as “decrease” as the trend information. Here, a medical worker or the like can register the call type of the specific call operation unit 4 by inputting the call type information and the trend information through an input unit (not shown) and storing the information in the storage unit 14.

  In the present embodiment, when the symptom of the patient who uses the nurse call cordless handset 1 is recovered, the tendency of the storage unit 14 indicates whether the operation frequency of the specific call operation unit 4 is increasing or decreasing. Although stored in the area 143, the present invention is not limited to this. For example, when the symptom of the patient who uses the nurse call cordless handset 1 is getting worse, the tendency area 143 of the storage unit 14 stores whether the operation frequency of the specific call operation unit 4 is increasing or decreasing. You may do it. Further, in this case, when call type information such as “affected part is painful” is stored in the call type area 142, “increase” is stored in the trend area 143. When call type information such as “desired to go out” is stored in the call type area 142, “decrease” is stored in the trend area 143.

  In the present embodiment, call type information such as “the pain of the affected area” or “desired to go out” is used as the call type, but is not limited thereto. For example, call type information such as “start-up assistance”, “want to eat”, “healthy” may be used as the call type.

  In addition, as shown in FIG. 2B, the storage unit 14 stores a call date / time area 144 that stores call date / time information indicating the call date / time when the patient made a specific call as history information. A handset number area 145 for storing handset identification information indicating the nurse call handset 1 is stored. In the call date / time area 144, information such as “3/10 9:00” is stored as the call date / time information. In the handset number area 145, information such as “001” is stored as handset identification information. Here, the call date / time information is obtained by a predetermined operation when a patient using the nurse call slave unit 1 is replaced by discharge or when a call type of the specific call operation unit 4 of the nurse call slave unit 1 is newly registered. Reset. Further, the storage unit 14 stores use start date and time information indicating the date and time when the call date and time information is reset in association with the child device identification information. In addition, the predetermined operation refers to an operation that designates the nurse call handset 1 to be used by a new patient when a patient is replaced and newly starts acquisition of the call date and time information, or the call of the specific call operation unit 4 When the type is newly registered, the nurse call handset 1 is designated, and this indicates an operation for newly starting acquisition of the call date / time information.

  The operation determination unit 11a determines whether or not the I / F unit 12 has input the specific call signal output from the nurse call slave unit 1 (in other words, whether or not the specific call operation unit 4 of the nurse call slave unit 1 has been operated). )). The operation determination unit 11a determines that the I / F unit 12 has input the specific call signal output from the nurse call slave unit 1 (in other words, the specific call operation unit 4 of the nurse call slave unit 1 has been operated). In this case, the control unit 11 operates the storage control unit 11b, acquires the child device identification information included in the specific call signal, and specifies the nurse call child device 1 on which the specific call has been performed. And the control part 11 operates the alerting | reporting part 13, and alert | reports a specific call. The operation determination unit 11a determines whether or not a predetermined operation has been performed. When the operation determination unit 11a determines that a predetermined operation has been performed, the control unit 11 operates the storage control unit 11b.

  The storage control unit 11b determines that the I / F unit 12 has input the specific call signal output from the nurse call slave unit 1 (in other words, the specific call operation unit 4 of the nurse call slave unit 1 has been operated). It operates when it is determined by the unit 11a. In addition, the storage control unit 11b performs a predetermined operation such that a patient using the nurse call slave unit 1 is replaced or a call type of the specific call operation unit 4 of the nurse call slave unit 1 is newly registered. It operates when it is determined by the operation determination unit 11a. The control unit 11 acquires date / time information indicating the current date / time from a clock unit (not shown). Then, the storage control unit 11b associates the date and time information acquired by the control unit 11 with the child device identification information acquired when the control unit 11 operates the notification unit 13, and stores it in the storage unit 14 as call date and time information. Further, the storage control unit 11b associates the date and time information acquired by the control unit 11 with the child device identification information specified by a predetermined operation, and causes the storage unit 14 to store the information as the start date and time information.

  The totaling unit 11c totals the frequency information indicating the operation frequency of the specific calling operation unit 4 for a plurality of predetermined periods from the call date and time information and the handset identification information stored in the storage unit 14 for each nurse call handset 1. To do. Here, in this embodiment, since one nurse call handset 1 includes one specific call operation unit 4, the counting unit 11 c counts frequency information for each nurse call handset 1. In the present embodiment, the plurality of predetermined periods are two consecutive periods (for example, 24 hours up to an arbitrarily designated time point and 24 hours before that). In addition, in order for the counting unit 11c to count the frequency information, call date information (in this embodiment, call date information for at least 48 hours) corresponding to the period to be tabulated is stored in the storage unit 14. There is a need. That is, it is necessary that the period from the date / time according to the use start date / time information to the date / time when the aggregation starts is 48 hours or more.

  When a medical worker or the like operates a start operation unit (not shown) provided in the nurse call parent device 10, the control unit 11 operates the counting unit 11c. In addition, the control unit 11 refers to the storage unit 14 to check whether or not the call date and time information for 48 hours until the start operation unit is operated is stored in the storage unit 14. Specifically, the control unit 11 calculates a date and time that is 48 hours back from the time when the start operation unit is operated, and the date and time according to the use start date and time information stored in the storage unit 14 is before the calculated date and time. It is determined whether or not. When the control unit 11 determines that the date / time according to the use start date / time information is before the calculated date / time, the counting unit 11c calculates 24 hours until the start operation unit is operated as the first period, The previous 24 hours are calculated as the second period. Here, the totaling unit 11c extracts the call date and time information from the storage unit 14 for the first period and the second period, respectively, and the child stored in the storage unit 14 in association with the extracted call date and time information. Acquire machine identification information. The totaling unit 11c totals the frequency information for each nurse call handset 1 in two consecutive periods based on the acquired handset identification information.

  The change determination unit 11d determines a change in the physical condition of the patient who operated the specific call operation unit 4 from the frequency information values totaled by the totalization unit 11c. Here, the change determination unit 11d starts the operation when the counting unit 11c totals the frequency information in the two periods. The change determination unit 11d compares the frequency information in the two periods tabulated by the tabulation unit 11c. Moreover, when comparing the values of the frequency information, the change determination unit 11d obtains the frequency information of the first period that is the latest period with respect to the frequency information of the second period that is the old period of the two periods. The change is judged by looking.

  In addition to the frequency information comparison process performed by the change determination unit 11d, the control unit 11 is associated with the slave unit identification information used by the aggregation unit 11c to aggregate the frequency information and is stored in the storage unit 14. Get trend information. When the value of the trend information acquired by the control unit 11 is “decrease”, the change determination unit 11d determines that the operation frequency of the specific call operation unit 4 is increased by comparing the values of the frequency information. The change determination unit 11d determines that the patient's physical condition has deteriorated. Further, when the value of the trend information acquired by the control unit 11 is “decrease”, the change determination unit 11d determines that the operation frequency of the specific call operation unit 4 is decreased by comparing the values of the frequency information. Then, the change determination unit 11d determines that the patient's physical condition is recovered.

  On the other hand, when the value of the trend information acquired by the control unit 11 is “increase”, the change determination unit 11d determines that the operation frequency of the specific call operation unit 4 is increased by comparing the values of the frequency information. Then, the change determination unit 11d determines that the patient's physical condition is recovered. Further, when the value of the trend information acquired by the control unit 11 is “increase”, the change determination unit 11d determines that the operation frequency of the specific call operation unit 4 is decreased by comparing the values of the frequency information. Then, the change determination unit 11d determines that the patient's physical condition has deteriorated.

  The display unit 15 displays the result determined by the change determination unit 11d, and includes a display display. Here, when the change determination unit 11d determines that the patient's physical condition is deteriorated, the control unit 11 causes the display unit 15 to display that the patient's physical condition is deteriorated. On the other hand, when the change determination unit 11d determines that the patient's physical condition is recovered, the control unit 11 causes the display unit 15 to display that the patient's physical condition is recovered.

  Next, a specific example of determining the recovery condition of the patient's physical condition using each information stored in advance in the storage unit 14 shown in FIG. 2 will be described. Further, in this example, it is assumed that two consecutive periods in which the counting unit 11c performs counting are set to 48 hours.

  First, the storage unit 14 stores handset identification information, call type information, and trend information in association with each other. Further, the storage unit 14 stores the call date and time information for 48 hours from 3/10 0:00, which is the use start date and time information, and the slave unit identification information in association with each other. Further, a specific call operation unit in the case where “the affected part is painful” is registered as the call type information of the child machine number 001 and the symptoms of the patient using the nurse call child machine 1 of the child machine number 001 are recovered. “Decrease” is registered as the trend information of the operation frequency 4. Further, “rising assistance” is registered as the call type information of the child machine number 002, and the symptom of the patient who uses the nurse call child machine 1 of the child machine number 002 is recovered. “Decrease” is registered as trend information of the operation frequency. In addition, “desired to go out” is registered as the call type information of the child device number 003, and the symptom of the patient who uses the nurse call child device 1 of the child device number 003 is recovered. “Increase” is registered as trend information of operation frequency. In addition, “desired to go out” is registered as the call type information of the child machine number 004, and the symptom of the patient who uses the nurse call child machine 1 of the child machine number 004 is recovered. “Increase” is registered as trend information of operation frequency.

  In this state, when a medical worker or the like operates the operation start unit provided in the nurse call parent device 10, the control unit 11 operates the totaling unit 11c. Moreover, the control part 11 calculates the date and time which went back 48 hours before the time (3/12 0:00) when the start operation part was operated. The control unit 11 determines whether or not the date and time based on the use start date and time information stored in the storage unit 14 is before the calculated date and time (3/10 0:00). Since the calculated date and time (3/10 0:00) is the same as the value of the use start date and time information, the totaling unit 11c takes 24 hours until the time when the start operation unit is operated (3/12 0:00). The first period (24 hours up to 3/12 0:00) is calculated, and the previous 24 hours are calculated as the second period (24 hours up to 3/11 0:00).

  Here, the totaling unit 11c extracts the call date and time information from the storage unit 14 for the first period and the second period, respectively, and the child stored in the storage unit 14 in association with the extracted call date and time information. Acquire machine identification information. The counting unit 11c uses the acquired slave unit identification information to obtain frequency information for each nurse call slave unit 1 in two consecutive periods (the number of calls 3/10 of the nurse call slave unit 1 with the slave unit number 001 is one). Yes, the number of calls for 3/10 of the nurse call handset 1 of the handset number 002 is 3, and the number of calls for 3/10 of the nurse call handset 1 of the handset number 003 is 2, and the handset The number of calls of 3/10 of the nurse call handset 1 with the number 004 is 2 and the number of calls of 3/11 with the number 1 of the nurse call handset 1 of the handset number 001 is 3, and the number of the nurse call number 002 is 3 The number of calls on 3/11 of the call handset 1 is 1, the number of calls on 3/11 of the nurse call handset 1 with the handset number 003 is 4, and the nurse call handset 1 with the handset number 004 Of 3/11 calls To aggregate the matter is).

  The change determination unit 11d compares the frequency information in the two periods tabulated by the tabulation unit 11c. Moreover, the change determination part 11d determines a change by seeing the frequency information of the 1st period which is the newest period with respect to the frequency information of the 2nd period which is an old period among two periods.

  In addition to the frequency information comparison process performed by the change determination unit 11d, the control unit 11 is associated with the slave unit identification information used by the aggregation unit 11c to aggregate the frequency information and is stored in the storage unit 14. The trend information value of the nurse call slave unit 1 with the slave unit number 001 is “decrease”, the trend information value of the nurse call slave unit 1 with the slave unit number 002 is “decrease”, and the slave unit The trend information value of the nurse call handset 1 with the number 003 is “increase”, and the trend information value of the nurse call handset 1 with the number 004 is “increase”).

  The value of the trend information of the nurse call slave unit 1 of the slave unit number 001 is “decrease”, and the number of calls (3 cases) of 3/11 of the nurse call slave unit 1 of the slave unit number 001 is the nurse of the slave unit number 001 The change determination unit 11d determines that the number of calls of the call handset 1 is increased as compared to 3/10 (1). Then, the change determination unit 11d determines that the patient's physical condition has deteriorated. And the control part 11 displays on the display part 15 that the physical condition of the patient who uses the nurse call subunit | mobile_unit 1 of the subunit | mobile_unit number 001 has deteriorated as a result determined by the change determination part 11d.

  Further, the value of the trend information of the nurse call slave unit 1 with the slave unit number 002 is “decrease”, and the number of calls (one) of 3/11 of the nurse call slave unit 1 with the slave unit number 002 is the slave unit number 002. The change determination unit 11d determines that the number of calls (3 cases) of 3/10 of the nurse call cordless handset 1 has decreased. Then, the change determination unit 11d determines that the patient's physical condition is recovered. And the control part 11 displays on the display part 15 that the physical condition of the patient who uses the nurse call subunit | mobile_unit 1 of the subunit | mobile_unit number 002 is recovering as a result determined by the change determination part 11d.

  In addition, the value of the trend information of the nurse call slave unit 1 with the slave unit number 003 is “increase”, and the number of calls (4 cases) of 3/11 of the nurse call slave unit 1 with the slave unit number 003 is the slave unit number 003. The change determination unit 11d determines that the number of calls (2 cases) of 3/10 of the nurse call cordless handset 1 is increased. Then, the change determination unit 11d determines that the patient's physical condition is recovered. And the control part 11 displays on the display part 15 that the physical condition of the patient who uses the nurse call subunit | mobile_unit 1 of the subunit | mobile_unit number 003 is recovering as a result determined by the change determination part 11d.

  Further, the value of the trend information of the nurse call slave unit 1 with the slave unit number 004 is “increase”, and the number of calls (one) of 3/11 of the nurse call slave unit 1 with the slave unit number 004 is the slave unit number 004. The change determination unit 11d determines that the number of calls (2 cases) of 3/10 of the nurse call cordless handset 1 has decreased. Then, the change determination unit 11d determines that the patient's physical condition has deteriorated. And the control part 11 displays on the display part 15 that the physical condition of the patient who uses the nurse call subunit | mobile_unit 1 of the subunit | mobile_unit number 004 has deteriorated as a result determined by the change determination part 11d.

  As described above in detail, in the nurse call system of the present embodiment, the slave identification information for identifying the nurse call slave 1 used by the patient and the call identification information indicating the call type that matches the symptom of the patient. And the trend information indicating whether the operation frequency of the specific call operation unit 4 is increasing or decreasing when the patient's symptoms are recovered are stored in the storage unit 14 in association with each other. Then, when the patient makes a specific call, the storage control unit 11b associates the call date and time information indicating the date and time when the specific call is made with the child device identification information, and stores them in the storage unit 14. When this call date and time information is stored for two periods and the display of the patient's physical condition is instructed, the counting unit 11c calculates the call date and time information stored in the storage unit 14 and the slave unit identification information. The frequency information indicating the operation frequency in one period is totaled for each nurse call handset 1. The change determination unit 11d performs a specific call operation from the frequency information tabulated by the tabulation unit 11c and the trend information stored in the storage unit 14 in association with the slave unit identification information used for tabulating the frequency information. The change of the physical condition of the patient who operated the unit 4 is determined. Thereby, the medical worker can grasp | ascertain the recovery | restoration state of the physical condition of the patient who operated the specific call operation part 4 from the determination result. Therefore, the medical staff can easily and appropriately determine the recovery of the patient's physical condition without being limited to events related to the number of body movements and events that can be detected by a sensor.

  In the embodiment described above, the counting unit 11c extracts the call date and time information in units of time, but is not limited thereto. For example, the totaling unit 11c may extract the call date information on a daily basis or a weekly basis.

  In the above-described embodiment, two consecutive periods are set as a plurality of predetermined periods. However, the present invention is not limited to this. For example, two consecutive periods may be set as a plurality of predetermined periods, or three or more periods may be set as a plurality of predetermined periods. In that case, the change determination part 11d should just compare the value of the frequency information of each period.

  In the above-described embodiment, the first period is 24 hours until the start operation unit is operated, and the previous 24 hours is the second period. However, the present invention is not limited to this. For example, the first period may be 24 hours before the date and time designated by a healthcare worker or the like, and the previous 24 hours may be the second period.

  In the above-described embodiment, when a medical worker operates the start operation unit, the control unit 11 displays on the display unit 15 whether the patient's physical condition is recovered or deteriorated. Not. For example, at the timing when the first period ends or at a predetermined timing, the control unit 11 may automatically display on the display unit 15 whether the patient's physical condition has recovered or deteriorated.

  In the above-described embodiment, the storage unit 14, the operation determination unit 11a, the storage control unit 11b, the totaling unit 11c, and the change determination unit 11d are provided in the nurse call parent device 10, but are not limited thereto. For example, the storage unit 14, the operation determination unit 11a, the storage control unit 11b, the totaling unit 11c, and the change determination unit 11d may be provided in a controller (not shown).

  In the above-described embodiment, the display unit 15 is provided in the nurse call parent device 10, but is not limited thereto. For example, the display unit 15 may be provided in a mobile communication terminal (not shown) carried by a medical worker.

  In the above-described embodiment, the storage control unit 11b stores the date and time when the patient operated the specific call operation unit 4 of the nurse call slave device 1 in the storage unit 14 as the call date and time information, but is not limited thereto. . For example, the storage control unit 11b may store the date and time when the medical worker responds to a specific call in the storage unit 14 as the call date and time information.

  In the embodiment described above, the nurse call slave device 1 includes the one specific call operation unit 4, but is not limited thereto. For example, the nurse call handset 1 may be configured to include two or more specific call operation units 4. In this case, the storage unit 14 needs to store the call type information and the trend information in advance in association with each specific call operation unit 4 of each nurse call slave unit 1, and the slave unit control unit 2 The specific call signal is generated by distinguishing the specific call signal so that the nurse call master unit 10 can recognize which specific call operation unit 4 is operated (for example, to identify the operated specific call operation unit 4). For example, generating a specific call signal including the information of

  In the above-described embodiment, the storage control unit 11b stores date / time information indicating the current date / time acquired by the control unit 11 from a clock unit (not shown) as the call date / time information indicating the call date / time when the patient made a specific call. 14, but is not limited to this. For example, the storage control unit 11b may cause the storage unit 14 to store frequency information indicating the number of times the patient has made a specific call during a predetermined period (for example, 24 hours). Specifically, the control unit 11 counts the number of times that a specific call is made in a predetermined period for each nurse call handset 1 and outputs the number of times as number information. Moreover, the control part 11 outputs the subunit | mobile_unit identification information of the nurse call subunit | mobile_unit 1 used as the object for counting. Then, the storage control unit 11b stores the number-of-times information output from the control unit 11 and the slave unit identification information in the storage unit 14 in association with each other. In that case, the totaling unit 11c totals the frequency information from the number-of-times information stored in the storage unit 14 and the slave unit identification information. This eliminates the need to provide the nurse call parent device 10 with a clock unit for measuring the current time.

  In addition, the configuration, processing procedure, contents, and the like of the nurse call system can be variously modified and implemented without departing from the gist of the present invention. Moreover, various inventions can be formed by combining a plurality of constituent elements disclosed in the embodiment. For example, you may make it delete a some component from all the components shown by embodiment. Furthermore, you may make it combine the component covering different embodiment suitably.
