Nurse call system

Abstract

This system provides a nurse call system that can prevent false detections related to patient motion detection. [Solution] A terminal detection device 10 capable of detecting a mobile terminal 4 via wireless communication with the mobile terminal 4 located in the patient room was installed in each patient room. The terminal detection ID of each terminal detection device 10 and the sensor ID of each mat sensor 9 were stored in the control unit 7, each associated with a patient room, and as a result, the terminal detection device 10 and the mat sensors 9, 9... were stored in association. While the terminal detection device 10 was detecting a mobile terminal 4, the control unit 7 did not interpret the detection as a patient getting out of bed, even if a load was detected on the mat 8 by the mat sensor 9, 9... associated with the patient room where the terminal detection device 10 was installed, and therefore did not notify the nurse call master unit 3.

Description

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the nurse call system described in Patent Document 1, for example, a situation where a nurse approaches the bed to assist a patient is detected as a leaving-the-bed operation of the patient to be notified, and there is a problem that notifications are made to the nurse call master unit one by one.

[0005] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a nurse call system capable of preventing false detection related to detection of patient operations.

Means for Solving the Problems

[0006] To achieve the above objective, the invention described in claim 1 of the present invention comprises a nurse call sub-unit for a patient to call a nurse, a nurse call master unit for responding to calls from the nurse call sub-unit, a control unit for controlling communication between the nurse call sub-unit and the nurse call master unit, a person detection means for detecting a predetermined action by a patient, a notification means, and a control means, wherein the control means executes a notification operation to activate the notification means when a predetermined detection result is obtained by the person detection means, and is provided with a terminal detection means capable of detecting a mobile terminal carried by a nurse, and the terminal detection means and the person detection means are associated and stored in the control means, and when the terminal detection means detects a mobile terminal, the control means does not execute a notification operation even if a predetermined detection result is obtained by the person detection means corresponding to the terminal detection means. According to the invention described in claim 1, a terminal detection means capable of detecting a mobile terminal carried by a nurse is provided, and the control means stores the terminal detection means and the person detection means in association with each other. When the control means detects a mobile terminal using the terminal detection means, it contacts the person detection means corresponding to the terminal detection means and does not perform a notification operation even if a predetermined detection result is obtained. Therefore, it is possible to create a nurse call system that does not erroneously detect, for example, a situation where a nurse approaches a patient's bed to assist them as a patient leaving bed, which should be notified.

[0007] Furthermore, in order to achieve the above objective, the invention described in claim 2 of the present invention comprises a nurse call sub-unit for a patient to call a nurse, a nurse call master unit for responding to calls from the nurse call sub-unit, a control unit for controlling communication between the nurse call sub-unit and the nurse call master unit, a plurality of person detection means for detecting a predetermined action by a patient, a notification means, and a control means, wherein the control means executes a notification operation to activate the notification means when a predetermined detection result is obtained by the person detection means, and is provided with a plurality of terminal detection means capable of detecting a mobile terminal carried by a nurse, and the terminal detection means and the person detection means are associated and stored in the control means, and when the plurality of terminal detection means detect a mobile terminal, the control means identifies the terminal detection means closest to the mobile terminal based on the detection result, and is characterized in that it does not execute a notification operation even if a predetermined detection result is obtained for the person detection means corresponding to the identified terminal detection means. According to the invention described in claim 2, a plurality of terminal detection means capable of detecting a mobile terminal carried by a nurse are provided, and the control means stores the terminal detection means and the person detection means in association with each other. When the control means detects a mobile terminal using the plurality of terminal detection means, it identifies the terminal detection means closest to the mobile terminal based on the detection result, and then, even if a predetermined detection result is obtained, it does not perform a notification operation with the person detection means corresponding to the identified terminal detection means. Therefore, it is possible to create a nurse call system that does not erroneously detect, for example, a situation where a nurse approaches a patient's bed to assist them as a patient leaving bed, which should be notified.

[0008] The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, if the control means does not perform a notification operation even if a predetermined detection result is obtained, it associates that fact with the terminal ID of the detected mobile terminal and stores it as a cancellation history. According to the invention described in claim 3, if the control means does not perform a notification operation even if a predetermined detection result is obtained, it associates that fact with the terminal ID of the mobile terminal that detected it and stores it as a cancellation history, making it easier to check and analyze the situation at a later date, and resulting in a more user-friendly nurse call system. [Effects of the Invention]

[0009] According to the present invention, a nurse call system can be created that does not mistakenly detect situations such as a nurse approaching a patient's bed to assist them as a patient leaving bed, which should be reported. [Brief explanation of the drawing]

[0010] [Figure 1] This is an explanatory diagram showing the overall configuration of the nurse call system. [Modes for carrying out the invention]

[0011] The following describes in detail, based on the drawings, a nurse call system that is one embodiment of the present invention.

[0012] Figure 1 is an explanatory diagram showing the overall configuration of the nurse call system. The nurse call system comprises nurse call sub-units 1, 1... installed at each bedside for patients to call a nurse, corridor lights 2, 2... installed near the entrance of the patient room that notify of calls made by the nurse call sub-units 1 by flashing, etc., and display patient information in the patient room, a nurse call master unit 3 installed at the nurse station, etc., that notifies of calls made by the nurse call sub-units 1, 1... and responds to those calls, mobile terminals 4, 4... such as smartphones carried by each nurse to respond to calls from patients, base stations 5, 5... such as access points that communicate with the mobile terminals 4, 4..., a switch 6 for managing communication via the base station 5, a controller 7 for controlling calls / communications between each device, mat sensors 9, 9... as means of detecting people installed on mats 8, 8... arranged adjacent to each bed, and terminal detection devices 10, 10... installed on the ceiling of each patient room as means of detecting the position of the mobile terminals 4. Furthermore, the corridor lights 2, 2..., the nurse call master unit 3, and the exchange 6 are connected to the control unit 7 via LAN line L1. In addition, each nurse call slave unit 1 is connected to the corridor light 2 via transmission line L2, and each mat sensor 9 is connected to the corridor light 2 via transmission line L4. Moreover, each terminal detection device 10 is connected to the control unit 7 via transmission line L3 and is capable of wireless communication with the mobile terminals 4, 4..., allowing for detection of the mobile terminals 4, 4... based on the availability of this wireless communication.

[0013] Furthermore, the nurse call system uses mat sensors 9, 9... to detect when a patient leaves their bed, in other words, when a patient gets out of bed. Specifically, when the control unit 7 detects the load caused by the patient being on the mat 8 using the mat sensor 9, it determines that a patient has gotten out of bed and notifies the nurse call master unit 3, which then displays the notification on the screen of the nurse call master unit 3.

[0014] Furthermore, when the terminal detection device 10 detects a mobile terminal 4 carried by a nurse, it determines that a nurse is in the patient room where the terminal detection device 10 is installed. If a nurse is in the patient room, it is quite possible that the nurse will move onto the mat 8 to assist the patient. Therefore, while the terminal detection device 10 is detecting the mobile terminal 4, even if the mat sensors 9, 9... associated with the patient room where the terminal detection device 10 is installed detect a load on the mat 8, the detection is not interpreted as a patient getting out of bed, and naturally, no notification is sent to the nurse call master unit 3. However, the terminal detection device 10 obtains the terminal ID of the mobile terminal 4 through wireless communication with the mobile terminal 4. Then, when the control unit 7 detects a load on the mat 8 by the mat sensor 9 while the mobile terminal 4 is being detected by the terminal detection device 10, it associates the detection with the terminal ID and stores it as a cancellation history. This cancellation history can be displayed on the display unit of the nurse call master unit 3 by performing a specific operation on the nurse call master unit 3.

[0015] The terminal detection device 10 has a terminal detection ID, which is stored in the control unit 7 in association with the patient room. The mat sensor 9 also has a sensor ID, which is stored in the control unit 7 in association with the patient room. Therefore, when the terminal detection device 10 detects the mobile terminal 4, the control unit 7 can determine which mat sensor 9 is involved and whether to execute the control described above, which would not detect the patient getting out of bed.

[0016] In the nurse call system having the above configuration, a terminal detection device 10 capable of detecting a mobile terminal 4 via wireless communication with the mobile terminal 4 located in the patient room is installed in each patient room. Furthermore, the terminal detection ID of each terminal detection device 10 and the sensor ID of each mat sensor 9 are stored in the control unit 7, associated with each patient room, and as a result, the terminal detection device 10 and the mat sensors 9, 9... are associated with each patient room. While the terminal detection device 10 is detecting a mobile terminal 4, the control unit 7 does not interpret the detection as a patient leaving bed, even if a load is detected on the mat 8 by the mat sensor 9, 9... associated with the patient room where the terminal detection device 10 is installed, and does not notify the nurse call master unit 3. Therefore, the nurse call system can be configured so as not to mistakenly detect situations such as a nurse moving onto the mat 8 to assist a patient as a patient leaving bed.

[0017] Furthermore, although the control unit 7 does not notify the nurse call master unit 3, when the mobile terminal 4 is detected by the terminal detection device 10 and the mat sensor 9 detects a load on the mat 8, it associates this detection with the terminal ID of the mobile terminal 4 and stores it as a cancellation history. Therefore, it is possible to make it easier to check and analyze the situation at a later date, resulting in a more user-friendly nurse call system.

[0018] Furthermore, the nurse call system according to the present invention is not limited in any way to the embodiments described above, and the overall configuration of the nurse call system, as well as the configurations related to the person detection means and terminal detection means, can be modified as necessary without departing from the spirit of the present invention.

[0019] For example, in the above embodiment, one terminal detection means is installed for each hospital room, but one terminal detection means may be installed for each bed. In that case, by adopting a well-known technique such as that described in Japanese Patent Application Laid-Open No. 2014-161346, based on the detection results of mobile terminals by a plurality of terminal detection means in the hospital room, it is possible to identify which terminal detection means the mobile terminal is close to. Therefore, for the person detection means corresponding to the terminal detection means at the closest position, even if a predetermined detection result is obtained, the notification operation may not be executed. By adopting such a configuration, the execution or non-execution of the notification operation based on the detection result of the person detection means can be controlled in more detail than in the above-described embodiment of the nurse call system, and a nurse call system that is less likely to have false detections can be achieved.

[0020] Also, in the above embodiment, a mat sensor is adopted as the person detection means, but for example, a camera that images the patient on the bed including the surrounding of the bed may be adopted as the person detection means, and specifically, what means to adopt as the person detection means can be appropriately changed. Furthermore, in the above embodiment, it is a nurse call system that controls whether to notify the getting-out-of-bed operation or not, but it is of course possible to configure it to control whether to notify or not for other operations such as the sitting-up operation in the same way.

[0021] Furthermore, in the above embodiment, the notification means is the screen of the nurse call master unit, but a speaker provided in the nurse call master unit may be adopted as the notification means, or the light of the corridor light may be made to light / blink as the notification means. In addition, in the above embodiment, the control unit is adopted as the control means, but the control means may be provided for the corridor light or the terminal detection means.
