However, according to the technology disclosed in Patent Document 1, predictions are made based only on the past calls from slave devices, so it is difficult to provide necessary nursing care, especially in cases where patients hesitate to call a nurse, such as when using the restroom. The problem was that no treatment could be taken. Further, according to the technique disclosed in Patent Document 2, it is necessary to separately introduce, install, and manage a sensor, which causes a problem of increased cost and effort.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a nurse call system that allows a nurse to check on a patient prior to making a nurse call while reducing the cost of introduction.

The nurse call system of the present invention includes a slave unit from which a patient calls a nurse, a base unit from which the nurse responds to calls from the slave unit, a mobile terminal carried by the nurse, and a mobile terminal that stores behavior information indicating the patient's behavior. a storage means for controlling the entire system, and a control means for analyzing behavior information and generating notification information to be notified to a mobile phone; and a transmission unit for transmitting the notification information to a mobile terminal. and the behavior information includes call information for calling the base unit from the slave unit, and the analysis unit totals the number of calls for each call time and call reason based on the call information, and calculates the number of calls. It is characterized in that notification information is generated when a predetermined threshold is exceeded. It is also equipped with a camera that takes pictures of the patient's surroundings and a wireless transmitter that reports the patient's whereabouts, and the behavior information includes image information input from the camera and location information input from the wireless transmitter, and is analyzed. The means analyzes the patient's behavior pattern based on the image information and/or the location information, and generates notification information based on the behavior pattern.

According to the nurse call system of the present invention, patient behavior information is obtained from nurse calls and existing equipment such as cameras and wireless transmitters placed in patient rooms and common areas, and the behavior information is analyzed to determine when a nurse is needed. Since the system predicts the situation in which the patient will receive care, even if the patient does not call for a nurse due to hesitation or hesitation, the patient can receive detailed care.

An embodiment embodying the nurse call system of the present invention will be described based on the drawings. As shown in FIG. 1, the nurse call system 1 of the present invention includes a handset 2, such as a plate handset, from which a patient Pb calls a nurse Pa, and a base device 3, from which the nurse Pa responds to a call from the handset 2. , a mobile terminal 4 carried by the nurse Pa, a cloud server 9 serving as a storage unit 22 that stores behavioral information that occurs in the patient Pb, and a control machine functioning as a control unit 21 that controls the entire nurse call system 1. 5, a bedside monitor 11 that notifies patient Pb of medication times and rounds of nurses Pa and doctors, and a patient camera 12b that captures image information such as images and videos of patient Pb, in the hallway of each hospital room. A wireless environment is provided within the hospital by the installed hallway lights 13, wireless transmitters 14 worn by nurses Pa and patients Pb, and wireless receivers 15 that receive radio waves from the wireless transmitters. An antenna base station, a telephone exchange (IP-BPX), a common area camera 12a for photographing the common area, a location information system 10 for identifying the positions of patients Pb and nurses Pa, LAN 7, and public network N. It consists of a cloud server 9 located at Note that the radio receivers 15 are installed at intervals of 5 m at various locations within the hospital, and transmit signals from the radio transmitter 14 to the position information system 10. Furthermore, the control unit 21 can also be placed in the nurse call server 8, the cloud server 9, etc., and the storage unit 22 can also be placed in the controller 5, the nurse call server 8, etc.

The main device 3 is placed at the nurse's station, the hallway light 13 is placed outside the hospital room, and the slave device 2, bedside monitor 11, and patient camera 12b are placed inside the hospital room. The handset 2, bedside monitor 11, and patient camera 12b are each connected to a hallway light 13. Furthermore, the base unit 3, the controller 5, the hallway light 13, the IP-PBX, the common area camera 12a, and the position information system 10 are each connected to the LAN 7 via the HUB 6, and the LAN 7 is connected to the public network N It is connected to the cloud server 9 via.

FIG. 2 is a block diagram in which the LAN 7 and HUB 6 are omitted. The control unit 21 includes a CPU that performs various calculations, an analysis unit 23 that analyzes behavioral information and generates notification information for calling the mobile terminal 4, and a transmission unit 24 that transmits the notification information to the mobile terminal 4. The mobile terminal 4 also includes a display unit 42 that displays notification information, and a response unit 41 that responds to the control unit 21 that the nurse Pa who has responded to the patient Pb has completed the response according to the displayed notification information. , a schedule management section 43 for managing the schedule of nurse Pa.

As shown in FIG. 3, the behavior information includes behavior information as call information that the patient Pb called the base unit 3 from the slave unit 2, and the behavior information includes, for example, a patient ID that uniquely identifies the patient Pb, Information such as the occurrence type including the call type, the time of occurrence including the calling time, and the reason including the calling reason is stored for each occurrence type. Note that the behavior information can be input or edited later by the nurse Pa. It is also preferable to configure the user interface so that the nurse Pa can input selections. Further, the behavior information may include information about the nurse Pa in charge of the patient Pb.

Furthermore, the behavior information includes various information regarding the patient Pb, such as image information input from the cameras 12 such as the common area camera 12a and the patient camera 12b, and position information input from the wireless transmitter 14. Specifically, patient Pb's habitual behavior in the hospital room, such as when he leaves his bed, when he walks in the hallway, when he goes in and out of the toilet cubicle, is recorded along with image/video information and location information. It is saved in the storage unit 22 as .

The analysis unit 23 performs statistical processing based on the behavior information, and analyzes when and what types of calls are made most often. For example, the number of occurrences is totaled for each occurrence time and reason, and when the number of occurrences exceeds a predetermined threshold, notification information is generated. The threshold value may be a fixed value such as "5, 6, 7, . . . n" or may be set as appropriate by the nurse Pa or the like. In the example of FIG. 3, three times is set as the threshold, and when the third toilet call occurs, notification information (see FIG. 4) is generated. By setting a threshold value, one or two one-off nurse calls can be excluded, and it is possible to avoid placing an excessive burden on the nurse Pa.

The analysis unit 23 also predicts the patient Pb's behavioral pattern, such as the patient's habitual behavior, based on the image information, the positional information, or both the image information and the positional information, and based on the predicted behavioral pattern. to generate notification information. In fact, there have been reports of accidents in which patient Pb hesitated to call for nurse Pa, resulting in patient Pb falling while exiting the toilet cubicle. Accidents can be avoided by having the teacher Pa wait in front of the private room.

As shown in FIG. 4, the notification information includes a patient ID that uniquely identifies patient Pb, a notification destination mobile terminal ID that uniquely identifies notification destination mobile terminal 4, patient Pb's location information, prediction reason, and prediction time. 52, a notification time 51 that is a predetermined time earlier than the predicted time 52, and the like. The notification time 51 can be set as appropriate, for example, 10 minutes before the predicted time 52. Multiple mobile terminals 4 to be notified can be selected including the nurse in charge of patient Pb, but it is also possible to select mobile terminal 4 of nurse Pa who is located closest to the position information of patient Pb at the notification time 51. . For example, depending on the reason for the prediction, it may be determined whether to call the nurse in charge Pa or a nearby nurse Pa.

The transmitter 24 transmits the notification information generated by the analyzer 23 to the mobile terminal 4 selected by the analyzer 23 as a notification destination.

As shown in FIG. 5, the control unit 21 notifies the mobile terminal 4 from the notification time 51 to the predicted time 52, and the mobile terminal 4 displays a pop-up 44 of notification information on the display unit 42. When the nurse Pa heading to the patient Pb finishes a predetermined treatment and taps the notification information icon, a confirmation button 45, which is the response section 41, is displayed. When the nurse Pa taps the confirmation button 45, response information is transmitted to the control unit 21.

When the control unit 21 receives response information from one of the mobile terminals 4 that transmitted the notification information, it stops notification to the other mobile terminals 4 that transmitted the notification information. Further, the control unit 21 continues the notification from the notification time 51 to the predicted time 52, and stops notification to all mobile terminals 4 when the predicted time 52 arrives without receiving response information.

The schedule management section 43 reads out the notification information generated by the analysis section 23 from the storage section 22 and displays on the display section 42 notification schedule information regarding which nurse Pa will receive the notification at which time in the future. By checking the notification schedule information, the nurse Pa can check the work status of the entire nurse.

Next, the operation of the nurse call system 1 of the present invention will be explained based on FIG. 6. In the nurse call system 1, behavioral information such as the behavior of the patient Pb and the nurse call from the handset 2 is always acquired and stored in the storage unit 22 at a predetermined timing (S1). The analysis unit 23 analyzes the behavior information at a predetermined timing (S2). If the number of occurrences exceeds the threshold, the analysis unit 23 generates notification information (S3). When the notification time 51 arrives, the transmitter 24 transmits the notification information to the destination mobile terminal 4 (S4). The mobile terminal 4 that has received the notification information displays the notification information on the display unit 42 (S5). At this time, the notification information is sent to a plurality of mobile terminals 4. When one of the nurses Pa who saw the notification information takes action on the patient Pb and taps the confirmation button 45 (S6: Yes), the control unit 21 controls the mobile phone carried by the nurse Pa other than the nurse Pa. A response completion notification is sent to the terminal 4 (S7). On the other hand, if the confirmation button 45 is not tapped (S6: No), the control unit 21 continues to notify the mobile terminal 4 until the predicted time 52 (S8: No). Then, when the predicted time 52 has arrived (S8: Yes), the control unit 21 stops notification to the mobile terminal 4 (S9).

According to the nurse call system 1 having the above configuration, patient Pb's behavioral information is recorded in detail, and the recorded behavioral information is analyzed to predict a situation in which nursing care is required. Even if you are in a situation where you cannot call a nurse, you can dispatch the nurse Pa in advance and deal with the situation in a detailed manner. Furthermore, since existing equipment such as the nurse call system, the camera 12 and the radio transmitter 14 placed in the hospital room and common area are used, there is no need to introduce new equipment, and costs can be reduced.

In addition, the present invention is not limited to the above-described embodiments, and the configuration of each part can be arbitrarily changed and implemented without departing from the spirit of the invention.
