The whole block diagram which shows the structure of the hospital management system of this embodiment. The flowchart which shows the processing content by the controller of FIG. FIG. 3 is an explanatory diagram illustrating an example of a display image displayed on the controller in FIG. 1.

  The in-hospital management system of the present embodiment shown in FIG. 1 is an in-hospital management system that at least spatially manages things in a hospital, and performs communication between the terminal 10 attached to a person and an article and the terminal 10. A sensing unit 20 and a controller 100 connected to the sensing unit 20 are provided.

  The terminal 10 is composed of, for example, a Zigbee (registered trademark, the same shall apply hereinafter) terminal that is a short-range wireless communication standard, and this Zigbee terminal is embedded in a patient identification band, as well as medical relations including doctors and nurses. It is built in the person's ID card. The terminal 10a attached to the patient and the medical staff is for specifying at least the type of patient, doctor, nurse, etc. and an individual (except a person who visits the hospital temporarily such as a visitor). A unique ID is written.

  The terminal 10 is also attached to inspection equipment, treatment equipment, medicines, and other equipment that needs management in the hospital. In the terminal 10b attached to such an article, at least the type of the article and a unique ID that identifies the article are written.

  In the present embodiment, the Zigbee terminals constituting the terminal 10 are Zigbee terminals (ZigBee End Device (ZED)) that do not have a relay function.

  A plurality of sensing means 20 are arranged in the hospital at predetermined intervals, and are composed of Zigbee terminals that communicate with the terminal 10. The Zigbee terminal that constitutes the sensing means 20 is a Zigbee terminal (ZigBee Router (ZR)) having a data relay function, and the sensing means 20 that communicates with the ID data read from the terminal 10 and the terminal 10. The relay history data of the sensing means 20 that relayed the data is transmitted to the controller 100.

  The sensing means 20 communicates with the terminal 10 and relays data with the adjacent sensing means 20, in addition to the function as a Zigbee terminal, in addition to existing human detection such as an infrared sensor. Means 21 are provided. Therefore, as for the detection result of the human detection means 21, the position data of the human detection means 21 that has detected the person is relayed from the sensing means 20 and transmitted to the controller 100.

  More precisely, the relay history data of the sensing means 20 as the Zigbee terminal that first obtained the detection data from the human detection means 21 at the detection position and the sensing means 20 that relayed the data is transmitted to the controller 100.

  Further, the infrared sensor as the human detection means 21 may be an active sensor that detects, with a light receiver, the reflected light reflected from the object by the infrared light emitted from the projector, and is a weak infrared light emitted from a person (animal). It may be configured by a passive sensor that detects light with a light receiver.

  Next, the controller 100 includes a specifying unit 110, an object grasping unit 120, and an object database 130.

  First, the specifying unit 110 includes an ID specifying unit 111 and a position specifying unit 112.

  The ID specifying unit 111 specifies an individual or an article from the ID data of the terminal 10 transmitted via the sensing unit 20.

  The position specifying means 112 specifies the position of the person or article to which the terminal 10 is attached from the position of the sensing means 20 that first communicated with the terminal 10 from the relay history data. Further, the position specifying means 112 specifies the position where the person (animal) exists from the position of the sensing means 20 from which the detection data of the human detection means 21 is first output from the relay history data.

  Next, the thing grasping unit 120 includes a suspicious person extracting unit 121, a position change recognizing unit 122, a combination recognizing unit 123, and a thing matching unit 124.

  The suspicious person extracting unit 121 executes a process of extracting the suspicious person in the hospital based on the information of the person specified by the specifying unit 110.

  The position change recognizing unit 122 executes processing for recognizing time-series changes in the information of the person and the article specified by the specifying unit 110.

  The combination recognizing unit 123 executes a process of recognizing a combination of a person and an article that are present at close positions based on the information about the person and the article specified by the specifying unit 110.

  The thing matching unit 124 calculates the event event stored in the thing database 130 from the position change of the person and the article recognized by the position change recognition unit 122 and the combination of the person and the article recognized by the combination recognition unit 123. Execute matching process and extract corresponding event.

  Next, the thing database 130 stores information related to the unique ID of the person and the article written in the terminal 10 and the thing information referred to by the thing matching means 124. More specifically, the thing information stored in the thing database 130 corresponds to a plurality of variations of things specified from the position change of the person and the article and the combination of the person and the article.

  In the present embodiment, each means 110 to 130 configuring the controller 100 is configured by hardware such as a CPU, a ROM, and a RAM, and each of these means 110 to 130 is configured by common hardware. In addition, some or all of these means 110 to 130 may be configured by different hardware.

  The controller 100 is connected with a display unit 150 and a keyboard, a mouse, and the like (not shown) allowing operation by the user from a liquid crystal display unit or the like.

  A method of managing things in the hospital by the hospital management system configured as described above will be described with reference to FIGS.

  First, the controller 100 specifies, as the human detection position, the position of the sensing means 20 from which the detection data of the human detection means 21 is first output from the relay history data of the detection data of the human detection means 21 by the position specifying means 112. (FIG. 2 / STEP 11).

  Next, the controller 100 specifies the position of the sensing means 20 that first communicated with the terminal 10a from the relay history data of the communication data with the terminal 10a by the ID specifying means 111, and exists at that position from the ID. Persons (patients, medical personnel such as doctors and nurses, visitors) are identified (FIG. 2 / STEP 12).

  Next, the suspicious person extracting means 121 of the controller 100 compares the person detection position specified in STEP 11 with the position of the person specified in STEP 12, and if there is a position where these do not match, that is, a person without an ID It is determined whether it exists (FIG. 2 / STEP 21).

  Then, if there is a person without an ID as a result of the determination (YES in FIG. 2 / STEP 21), the suspicious person extracting means 121 executes the suspicious person notifying process (FIG. 2 / STEP 22), and then STEP 23 and subsequent steps. Execute the process.

  Here, as a suspicious person notification process, in addition to displaying that there is a suspicious person without an ID on the display unit 150 of the controller 100, a process of notifying the security room or the like of the presence and position of the suspicious person Etc. are included.

  On the other hand, if the result of determination by the suspicious person extracting means 121 is that there is no person without an ID (NO in STEP 2 in FIG. 2), the controller 100 does not execute the suspicious person notifying process in STEP 22 but the ID identifying means. 111, the position of the sensing means 20 that first communicated with the terminal 10b is identified from the relay history data of the communication data with the terminal 10b, and the article (examination device, treatment device, medicine, etc.) present at that location is identified from the ID. ) Is specified (FIG. 2 / STEP 23).

  Next, the controller 100 displays the person specified in STEP 12 and the position thereof, the article specified in STEP 23 and the position thereof on the display unit 15 (FIG. 2 / STEP 24). In addition, when the image of the previous processing cycle is already displayed on the display unit 15, the controller 100 updates the display to a new image based on the current processing cycle.

  As shown in an example of the display in FIG. 3, the controller 100 generates and displays an image in which the identified person and article are arranged on a map that reproduces the floor plan of the hospital on the display unit 15.

  In FIG. 3, an icon 151 in the shape of a person indicates the presence of the person on the screen, and P, N, D, V, etc. displayed on the icon 151 indicate the type of person. For example, P indicates a patient, N indicates a nurse, D indicates a doctor, and V indicates a visitor. Furthermore, the color of the icon 151 on the screen is also different depending on the type.

  On the other hand, a box-shaped icon 152 indicates the presence of an article on the screen, and the color and size of the icon on the screen differ depending on the type.

  When the suspicious person notification process is executed in STEP 22, the presence of the suspicious person and the position of the suspicious person are displayed (for example, in red) on the screen shown in FIG.

  Next, the controller 100 uses the position change recognizing means 122 for the person specified in STEP 12 and the position thereof and the article specified in STEP 23 and the position thereof from the previous processing cycle (previous value or previous value). The change is recognized from the difference (FIG. 2 / STEP 25).

  Next, the controller 100 determines whether or not the position change recognized by the position change recognition means 122 corresponds to an abnormal position change registered in advance in the thing database 130 by the thing matching means 124 (FIG. 2 / STEP 26). ).

  Specifically, for example, (1) access of outsiders (patients / visitors) to an outsider prohibited entry area (examination room, medicine store, nurse's place) registered in the thing database 130, ( 2) A matching process between an abnormal position change such as passing through the entrance / exit of the management patient and the position change recognized by the position change recognition unit 122 is performed.

  This makes it possible to detect whether the patient has gone out without permission, or to recognize how the patient has disappeared, when performing an object determination based only on the current values of the positions of the person and the article. Although it is not possible, by grasping things in the hospital from the change in position, it is possible to accurately grasp things in the hospital from continuous changes in people and goods in the hospital without grasping the things in the hospital in pieces. be able to.

  If there is an abnormal position change (YES in FIG. 2 / STEP 26), the controller 100 executes the abnormal position change notification process (FIG. 2 / STEP 27), and then executes the processes after STEP 28.

  Here, as the abnormal position change notification process, as shown in FIG. 3, in addition to displaying the corresponding thing (what abnormal position change is present) on the display unit 150 of the controller 100, the nurse's office And a process of notifying the security room or the like of the relevant thing and information indicating its position.

  On the other hand, if there is no abnormal position change (NO in STEP 26 in FIG. 2), the controller 100 does not execute the abnormal position change notification process in STEP 27, and the controller 100 recognizes the person identified in STEP 12 and its position by the combination recognition unit 123. Then, based on the article specified in STEP 23 and its position, a process of recognizing a combination of a person and an article existing in a close position is executed (FIG. 2 / STEP 28).

  Next, the controller 100 determines whether or not the combination of the person and the article existing in the close position is an abnormal combination registered in advance in the thing database 130 by the thing matching means 124 (FIG. 2 / STEP 29).

  Specifically, for example, (1) whether there is no abnormal combination in the combination of people, (2) whether there is an abnormal combination in the combination of the person and the article, or (3) It is determined whether there is an abnormal combination of the articles.

  (1) As a case where the combination of people is an abnormal combination, a combination of an isolated patient due to a designated infectious disease or the like and another patient or a visitor corresponds. (2) If the combination of a person and an article is an abnormal combination, in addition to a combination of a patient and a test device, treatment device, or drug that cannot be used for that patient, only nurses and doctors are allowed to use it. Combinations with testing equipment, treatment equipment, medicines, etc. (3) As a case where the combination of articles is an abnormal combination, a combination of an inspection device, a treatment device, and a medicine that are prohibited from being used simultaneously is applicable.

  If there is an abnormal combination (YES in FIG. 2 / STEP 29), the controller 100 executes an abnormal combination notification process (FIG. 2 / STEP 30), ends the series of processes, and returns.

  Here, as the abnormal combination notification process, the corresponding thing (what kind of abnormal combination is present) is displayed on the display unit 150 of the controller 100, and the relevant thing and its items are displayed in the nurse's office and the security room. The process etc. which alert | report the information which shows a position are included.

  On the other hand, when there is no abnormal combination (NO in STEP 2 / STEP 29), the series of processes is terminated and the process returns.

  As described above, according to the in-hospital management system of the present embodiment, not only the position of the patient is grasped, but also a person identified from the identifier of the terminal 10, that is, a related person such as a patient and a hospital staff. It is possible to accurately grasp in-hospital things from the temporal change and the spatial combination of the position of the medical device and the position of the hospital equipment.

  In the present embodiment, the configuration for sequentially executing the thing matching process based on the position change (FIG. 2 / STEP 26) and the thing matching process based on the combination (FIG. 2 / STEP 29) has been described. However, the present invention is not limited thereto. Is not to be done.

  For example, a thing set as a change in position and a combination may be registered in the thing database 130, and this may be notified when such a thing falls under the matching process. Moreover, you may make it alert | report only when both a position change and a combination are abnormal.

  As a result, even if the position change is abnormal, if this is an appropriate combination, for example, when going out accompanied by a nurse, this can be excluded from the notification target, and abnormal notification is frequently performed. Can be suppressed.

  In addition, according to the in-hospital management system of the present embodiment, data can be communicated with medical devices such as treatment devices and test devices that can be connected to Zigbee, which is a short-range wireless communication standard, via the sensing means 20. It is good. Thereby, data can be transmitted to the in-hospital server via the sensing means 20, and the treatment record and the test record can be read from the in-hospital server and displayed on the doctor's interface, etc. The labor and cost required for data management can be reduced, and it can contribute to smooth medical practice.

  Further, the terminal 10 may be combined with a portable transmission device for a nurse call. In this case, by providing the controller 100 or its display unit 150 at the nurse's station, it is possible to check on the display unit 150 the patient or the like that needs the assistance of the nurse and to correspond to the nearest nurse. Become.

  In the present embodiment, the case where the communication standard between the terminal 10 and the sensing unit 20 is Zigbee, which is a short-range wireless communication standard, is described as an example. However, the communication standard is not limited to this, for example, Communication standards such as RFID (Radio Frequency Identification) and Bluetooth (registered trademark) may be used.
