Description

  The present invention relates to a behavior status visualization device, and is particularly suitable for use in a device that tabulates values representing the behavior status of nurses in a hospital and visually visualizes and displays the result of the tabulation.

  2. Description of the Related Art Conventionally, there has been known a technology capable of detecting and displaying a flow line which is a movement track of a nurse in a hospital (for example, see Patent Documents 1 and 2). By deriving the flow line of the nurse, it is possible to accurately grasp what kind of movement the nurse performs in the hospital in nursing work. Then, it is possible to improve work efficiency by finding useless movements of the nurse.

  Patent Literature 1 discloses that a device (for example, a wireless ID tag) carried by a nurse is detected by a device (for example, a tag reader device) installed at a plurality of places (for example, a hospital room, an examination room, etc.) in a hospital. The document describes that a plurality of positions visited by a nurse are recorded to derive a flow line of the nurse. Further, in Patent Document 2, a moving path when a nurse measures the temperature of each patient in a certain hospital room is represented by a flow line, and a hospital room map in which the residence time at each bed position is represented by the size of a point is displayed. It is described.

  By the way, there are various tasks performed by a nurse, such as a task of responding to a nurse call, a task of nursing a patient in charge, a task of supporting a doctor, and a task of recording a nursing record. As for the task of responding to a nurse call, not only a nurse call from a patient in charge but also help for a nurse call from a patient not in charge may be provided.

  In order to verify whether or not such various tasks can be performed efficiently, it is conceivable to visualize and display the flow line of the nurse, but if all the flow lines for the entire day or for a predetermined period are displayed, the display will be displayed. The moving lines are mixed up and it is hard to see. In addition, when the same position of the IC tag is repeatedly received by the same receiver, a technique of displaying a trace of the movement excluding the trace to the point where the IC tag is received again to provide a simple display and make the display screen easier to see. It is known (for example, see Patent Document 3). However, this makes it impossible to correctly grasp all the flow lines of the nurse, which is insufficient for grasping the work situation of the nurse.

  As another example of a system that acquires and visualizes information related to behavior from a person's position history, a two-dimensional plane representing the position is displayed with a time element added, and multiple places are visited by any number of routes. There is also known a technique in which it is possible to grasp at a glance whether the operation has been performed (see, for example, Patent Document 4). In this Patent Document 4, the place where the user stayed in one trip is represented by a double circle, the travel route between them is represented by a line, and the total stay time of the place of stay is represented by the radius of the circle. It describes that a world map in which the number of visits to each stay place is indicated by characters beside a circle is displayed.

  In addition, the mobile terminal calculates the frequency of visiting a commercial area within a certain period (average visit frequency), and further calculates the stay time when the mobile terminal visits the commercial area (average stay time), There is also known a technique for simultaneously displaying the calculated frequency (average visit frequency) and the stay time (average stay time) in a graph (for example, see Patent Document 5). Specifically, it describes that a graph is displayed with the average visit frequency on the horizontal axis and the average stay time on the vertical axis.

  The technique described in Patent Literature 4 is suitable for visualizing the movement history in one trip, but is not suitable for visualizing the work situation of a nurse who visits many places and performs various tasks. It is. There are many places where nurses stay (hospital rooms, consulting rooms, nurse stations, etc.), and it is common to visit various places many times. This is because it is difficult to display all of the lines representing the numbers and the numbers representing the number of visits on the hospital layout map, and even if they are displayed, they are complicated and difficult to see.

  Further, the technique described in Patent Document 5 merely maps the average visit frequency and average stay time to a specific place on two-dimensional coordinates and displays the result on a graph. That is, the average visit frequency and the average stay time are not visualized and displayed on a map. Therefore, even if the technology described in Patent Literature 5 is applied to visualization of nursing work, it is difficult to understand at a glance how many times the hospital has visited and how long it has stayed, making it difficult to understand. .

  The present invention has been made in order to solve such a problem. In a system for summing up values representing the behavioral states of nurses in a hospital and visually visualizing and displaying the summed up results, It is an object of the present invention to allow a user to see at a glance how many times a nurse visits a place in a hospital and how much time he / she stayed at each place.

  In order to solve the above-mentioned problem, in the present invention, based on the behavior history information of the nurse in the hospital, the place visited by the nurse in the hospital, the number of visits and the stay time are analyzed, and the analyzed visited place The number of visits and the length of stay are displayed by a predetermined drawing on a layout image representing the arrangement of each place in the hospital. At this time, the display mode of the predetermined drawing is variably set in accordance with the first pattern change based on the number of visits and the second pattern change based on the stay time.

  According to the present invention configured as described above, a predetermined drawing is performed at a place visited by a nurse on a layout image representing an arrangement of each place in a hospital. It is possible to see at a glance whether or not a visit has been made. Further, the display mode of the predetermined drawing displayed at the visited place is variably set in accordance with the first pattern change with the number of visits as the axis and the second pattern change with the stay time as the axis. According to the aspect, it is possible to simultaneously grasp the number of visits to each place and the stay time. Thus, the user can see at a glance which place in the hospital the nurse has visited and how long the nurse has stayed.

It is a block diagram showing an example of functional composition of an action situation visualization device by this embodiment. It is a figure showing the example of hardware constitutions of the position detection system to which the action situation visualization device of this embodiment is applied. It is a figure showing an example of arrangement of a plurality of APs in a layout in a hospital. It is a figure showing an example of a heat map display (thing about one hospital room) by this embodiment. It is a figure showing an example of a heat map display (thing about the whole hospital layout) by this embodiment. It is a figure showing other examples of a heat map display (thing about one hospital room) by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a functional configuration example of the behavior situation visualization device according to the present embodiment. FIG. 2 is a diagram illustrating an example of a hardware configuration of a position detection system to which the behavior situation visualization device according to the present embodiment is applied.

  The position detection system shown in FIG. 2 uses a transmitting device (for example, a wireless ID tag or a wireless transmitting device) carried by a nurse by receiving devices (for example, a tag reader device or a wireless receiver) installed at a plurality of places in a hospital. ), And by sequentially recording the position of the receiving device that has received the signal, the position where the nurse has moved can be stored as action history information.

  As shown in FIG. 2, the position detection system of the present embodiment is installed in a wireless IC tag 10 carried by a nurse and a plurality of places in a hospital (for example, a hospital room, a nurse station, a consultation room, a corridor, etc.). A wireless LAN access point (AP) 20 and a terminal 30 for detecting the location of the wireless IC tag 10 (a nurse holding the same).

  The wireless IC tag 10 is an example of a portable wireless transmitter that transmits a signal at regular intervals. For example, the wireless IC tag 10 has a transmitting function of BLE (Bluetooth Low Energy: Bluetooth is a registered trademark), and transmits a signal including a tag address at regular intervals. Although only one wireless IC tag 10 is shown in FIG. 2 in a simplified manner, there are actually as many as the number of nurses.

  The AP 20 is an example of a wireless receiver that receives a signal transmitted from the wireless IC tag 10. The AP 20 transmits its own AP address to the terminal 30 in addition to the tag address included in the signal received from the wireless IC tag 10. Although only one AP 20 is shown in FIG. 2, the AP 20 is actually installed at a plurality of locations in a hospital. Among them, only the AP 20 within the communication range of the BLE receives the signal from the wireless IC tag 10. Then, the AP 20 that has received the signal from the wireless IC tag 10 transmits information including the tag address and the AP address to the terminal 30.

  FIG. 3 is a diagram showing an example of the arrangement of a plurality of APs 20 in a layout in a hospital. In the hospital layout shown in FIG. 3, there are a plurality of hospital rooms 301 to 310, a nurse station 311, a consultation room 312, and a corridor 313. The AP 20 is installed in each of a plurality of hospital rooms 301 to 310, a nurse station 311, a consultation room 312, and a corridor 313. That is, one AP 20 is installed in each of the hospital rooms 301 to 310, the nurse station 311, and the examination room 312, and APs 20 are installed in a plurality of locations in the corridor 313.

  The AP 20 and the terminal 30 are connected by, for example, a wired LAN cable. Alternatively, a plurality of APs 20 may be connected wirelessly, and a relay device (not shown) may be further provided to connect the relay device and the terminal 30 by wire. In this case, information is transmitted from the plurality of APs 20 to the relay device in a relay format, and the information transmitted from the plurality of APs 20 is transmitted from the relay device to the terminal 30 in a lump. The connection form between the plurality of APs 20 and the terminal 30 is arbitrary, and the present invention is not limited to a specific connection form.

  The terminal 30 detects which nurse (wireless IC tag 10) is at which location based on the tag address and the AP address included in the information transmitted from the AP 20. That is, the terminal 30 detects that the wireless IC tag 10 indicated by the tag address exists at the place where the AP 20 indicated by the AP address included in the information received from the AP 20 exists. The terminal 30 stores the position where the nurse has moved as the action history information by sequentially recording the tag address and the AP address together with the reception time in the database.

  When a plurality of APs 20 exist within the communication area of the BLE of the wireless IC tag 10, the plurality of APs 20 receive a signal from one wireless IC tag 10. In this case, among the information received by the terminal 30 from the plurality of APs 20, there are a plurality of information including the same tag address. In this case, the terminal 30 specifies any one of the plurality of APs 20 indicated by the AP address transmitted together with those tag addresses, and places the wireless IC indicated by the tag address in a place where the specified AP 20 exists. The presence of the tag 10 is detected.

  Specifically, the terminal 30 specifies any one AP 20 based on the received electric field strength (detected by each AP 20) transmitted from each AP 20 together with the tag address and the AP address. For example, the AP 20 having the highest received electric field strength is specified. Then, it detects that the wireless IC tag 10 exists at the place where the specified AP 20 exists.

  The terminal 30 has a function of analyzing the behavior status of the nurse based on the behavior history information accumulated as described above, and visualizing and displaying the result. This function is provided by the behavior situation visualization device 100 of the present embodiment, and the functional configuration is shown in FIG. Here, the same terminal 30 is configured to have both the function of accumulating the behavior history information of the nurse and the function of visualizing and displaying the behavior status analyzed from the behavior history information. A configuration may be provided.

  As shown in FIG. 1, the behavioral status visualization device 100 according to the present embodiment includes, as its functional components, a history information acquisition unit 11, a behavior analysis unit 12, a display control unit 13, a nurse designation unit 14, and a period designation unit 15. Have. Further, a history information storage unit 31 as a database is connected to the behavior situation visualization device 100 of the present embodiment.

  Each of the functional blocks 11 to 15 can be configured by any of hardware, a DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 11 to 15 is actually configured to include a CPU, a RAM, a ROM, and the like of a computer, and is realized by operating a program stored in the RAM or the ROM. Note that the program may be stored in another recording medium such as a hard disk or a semiconductor memory.

  The history information storage unit 31 stores the behavior history information of the nurse in the hospital. The history information acquisition unit 11 acquires action history information from the history information storage unit 31. For example, when the user operates the operation unit of the terminal 30 to instruct to visualize and display the nurse's behavior, the history information acquisition unit 11 acquires the behavior history information from the history information storage unit 31. I do.

  Here, the history information obtaining unit 11 selectively obtains, from the history information storage unit 31, the action history information regarding the desired nurse specified by the nurse specifying unit 14 through the operation of the operation unit by the user. That is, the nurse designation unit 14 designates a nurse to be subjected to the heat map display through the operation of the operation unit by the user. The history information acquisition unit 11 selectively acquires, from the history information storage unit 31, behavior history information on the nurse designated by the nurse designation unit 14.

  Further, the history information acquisition unit 11 acquires from the history information storage unit 31 the action history information for a desired period (for example, a specific day, several days, or several hours) specified by the operation of the operation unit by the user. I do. That is, the period specifying unit 15 specifies a target period for performing the heat map display through the operation of the operation unit by the user. The history information acquiring unit 11 selectively acquires, from the history information storage unit 31, action history information regarding the period specified by the period specifying unit 15.

  The behavior analysis unit 12 analyzes the location visited by the nurse, the number of visits, and the stay time in the hospital based on the behavior history information acquired by the history information acquisition unit 11. That is, the behavior analysis unit 12 determines in which of the hospital rooms 301 to 310, the nurse station 311, the consultation room 312, and the corridor 313 shown in FIG. Analyze how long you stayed.

  The display control unit 13 visualizes and displays the visit place, the number of visits, and the stay time analyzed by the behavior analysis unit 12 on a layout image representing the arrangement of each place in the hospital. Here, the display control unit 13 performs a predetermined drawing on the visit location on the layout image, thereby visualizing and displaying the visit location, the number of visits, and the stay time. In this embodiment, a heat map is displayed as an example of the predetermined drawing.

  In a normal heat map display, a display mode such as a display color is variably set according to the size of the total value. For example, in order to display a heat map on the number of visits, display colors in n stages corresponding to the number of visits are determined in advance. Then, when the user instructs to display the heat map of the number of visits, each place on the layout image is displayed in a display color corresponding to the total value of the number of visits, thereby performing a heat map display of the number of visits.

  The same applies to the case where a heat map is displayed for the stay time. That is, in order to display a heat map on the stay time, display colors in n stages according to the stay time are determined in advance. Then, when the user instructs to display the heat map of the stay time, each place on the layout image is displayed in a display color corresponding to the total value of the stay time, thereby performing the heat map display of the stay time.

  On the other hand, in the present embodiment, the display mode of the heat map is variably set in accordance with the first pattern change centered on the number of visits and the second pattern change centered on the stay time. For example, the display control unit 13 uses the color change as the first pattern change and the colored area change as the second pattern change, and sets the color and the colored area according to each total value of the number of visits and the stay time. Then, a heat map is displayed by coloring each visited place according to the set contents.

  Specifically, as a first pattern change with the number of visits as an axis, the less the number of visits, the cooler the color (for example, blue), and the more the number of visits, the warmer color (for example, red). The display color of each visited place is set according to the color change. In addition, as a second pattern change centering on the staying time, the coloring area of each visit place is changed according to the coloring area change in which the shorter the staying time, the smaller the coloring area and the longer the staying time, the larger the coloring area. Set.

  The assignment of the number of visits and the stay time to the color change and the colored area change may be reversed. That is, the color and the colored area are set in accordance with each total value of the number of visits and the staying time using the color change as the first pattern change regarding the number of visits and the color change as the second pattern change regarding the stay time. Then, a heat map may be displayed by coloring each visited place according to the set contents.

  FIG. 4 is a diagram illustrating an example of a heat map display according to the present embodiment. FIG. 4 shows a display example of one hospital room. In FIG. 4, for convenience of illustration, differences in display colors are represented by hatching differences. FIG. 4A shows a state in which the display color is set to a cool color because the number of visits is relatively small, and the colored area is set to be small because the stay time is relatively short. On the other hand, FIG. 4B shows a state in which the display color is set to a warm color system because the number of visits is relatively large, and the colored area is set large because the stay time is relatively long.

  In the example of FIG. 4, the heat map is displayed in such a manner that the colored portion gradually increases concentrically from the outer periphery of the rectangular area representing the hospital room toward the center point as the staying time increases. For example, the coloring area is classified into n stages according to the length of stay time, and a heat map display is performed using the classified coloring area. Nurse stations, consultation rooms, and corridors are displayed in a similar manner. Although the shape of the rectangular area differs depending on the location, the heat map display is performed by changing the coloring area concentrically according to each shape. By doing so, the size of the coloring area can be presented in an easily understandable manner in accordance with the display shape of each location displayed on the layout image.

  Similarly, display colors are classified into n stages from a cool color system to a warm color system according to the number of visits, and a heat map display is performed using the classified display colors. Although an example in which the display colors of the cool color system and the warm color system are used is described here, an n-stage heat map display may be performed using only the display color of the cool color system or only the warm color system.

  Note that the change pattern of the coloring area is not limited to the example shown in FIG. For example, the heat map display may be performed in such a manner that the coloring portion gradually increases concentrically from the center point of the rectangular area representing the hospital room toward the outer periphery as the staying time increases. As another example, heat map display is performed in such a manner that the colored portion gradually increases in a direction from one side of the rectangular area to the opposite side or in a direction from one point of the rectangular area to its diagonal point. It may be.

  FIG. 5 is a diagram showing an example of a heat map display of the entire layout image in which each visited place is drawn according to the pattern change of the display mode as shown in FIG. By performing such a heat map display, it is possible to simultaneously grasp which place in the hospital the nurse has visited, and the number of visits to the visited place and the staying time at the same time. Thus, the user can see at a glance which place in the hospital the nurse has visited and how long the nurse has stayed.

  For example, by simultaneously checking the number of visits to the patient's room and the staying time of the patient in charge or not in charge of the nurse, it is possible to easily grasp at a glance whether or not the patient is moving appropriately. In addition, when staying time is short despite many visits, it is assumed that there is a possibility that the nurse call may be causing unnecessary movement due to false reports, and the number of visits is small. Nevertheless, if the length of stay is long, it is possible to reconsider the guidance method of nurses by inferring that nursing work may not be performed quickly.

  As described above in detail, in the present embodiment, when the visit place, the number of visits, and the stay time analyzed by the behavior analysis unit 12 are displayed as a heat map on the layout image, the first pattern having the number of visits as an axis is used. The display mode of the heat map is variably set in accordance with the second pattern change centered on the change and the stay time. This makes it possible to simultaneously grasp the number of visits to each place and the staying time by the display mode of the heat map variably set in accordance with the two types of pattern changes. Then, the user can see at a glance how long he stayed.

  As the analysis contents performed by the behavior analysis unit 12, for example, when the behavior history information indicates that the nurse has stayed at one visited place for a predetermined time or more, the stay time is calculated. The number of visits may be calculated irrespective of whether the nurse has stayed at one visit place for a predetermined time or more. In this way, by confirming the heat map display, it is possible to grasp the stay time when nursing work is actually performed in a hospital room and the like, and to grasp the total number of visits including false calls of nurse calls. be able to. As a result, in a hospital room where a large number of nurse call misinformation has occurred, the stay time tends to be shortened despite a large number of visits, so that it is easy to find a useless movement of a nurse due to the misinformation.

  The change pattern of the heat map display assigned to the number of visits and the stay time is not limited to the example shown in the above embodiment. For example, the display control unit 13 uses one of the color change and the color density change as the first pattern change related to the number of visits, and uses the other of the color change and the color density change as the second pattern change related to the staying time. Colors and coloring densities according to the number of times and the staying time may be set, and each visit place on the layout image may be colored as a heat map display.

  Alternatively, as shown in FIG. 6, the display control unit 13 displays a graphic in each visited place as a predetermined drawing, and changes the size of the graphic or coloring of the graphic as a first pattern change regarding the number of visits. Using one of the color changes and setting the size and color according to the number of visits and the stay time using the other of the change in the size of the figure or the change in the coloring of the figure as the second pattern change regarding the stay time Alternatively, a graphic may be displayed in each visited place on the layout image.

  FIG. 6 shows a display example of one hospital room. In FIG. 6, for convenience of illustration, differences in display colors are represented by hatching differences. FIG. 6A shows a state in which the display color of the figure (for example, a circle) is set to a warm color because the number of visits is relatively large, and the area of the circle is set to be large because the stay time is relatively long. Is shown. On the other hand, FIG. 6B shows a state in which the display color is set to a cool color because the number of visits is relatively small, and the area of the circle is set to be small because the stay time is relatively short. .

  Further, in the above-described embodiment, an example has been described in which the number of visits and the stay time are totaled by designating a specific nurse, but the number of visits of the entire nurse in the hospital can be specified by the user through the operation of the operation unit. The total value or the average value of the stay times may be totaled.

  In addition, each of the above-described embodiments is merely an example of the embodiment for carrying out the present invention, and the technical scope of the present invention should not be interpreted in a limited manner. That is, the present invention can be embodied in various forms without departing from the spirit or main features thereof.
