  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram showing the overall configuration of the patient identification system of the present embodiment. The patient identification system of the present embodiment includes a terminal 1 (patient identification terminal) used by medical staff (for example, doctors, nurses, etc.), a server 2, and a transmitter 3 installed in each of a plurality of beds. Prepare. It is assumed that the terminal 1 and the server 2 can communicate via a wireless network or a wired network.

  In the present embodiment, the case where the transmitter 3 is installed in a bed for dialysis treatment to identify (specify) a dialysis patient will be described below as an example, but the present invention is not limited to this. For example, it can be used when a hospital bed other than dialysis treatment identifies an inpatient.

  The terminal 1 is a device that identifies a patient in the bed and displays data of the identified patient. As the terminal 1, a communication device (mobile terminal) such as a tablet terminal or a smartphone can be used. The illustrated terminal 1 includes a reception unit 11, a selection unit 12, an acquisition unit 13, and a storage unit 14.

  The receiving unit 11 receives radio waves transmitted from the transmitter 3 installed in each of the plurality of beds. The selection unit 12 selects the transmitter 3 closest to the terminal 1 using the radio wave intensity of the radio wave transmitted from the transmitter 3. In the present embodiment, the selection unit 12 determines whether or not the distance between the terminal 1 and each transmitter 3 is within a predetermined distance using the radio wave intensity, and the transmitter 3 within the predetermined distance Thus, the transmitter 3 that is close to the terminal 1 is selected as the transmitter 3 that is the closest to the terminal 1.

  In addition, the selection unit 12 extracts the transmitter 3 whose distance from the terminal 1 is within a predetermined distance as a monitoring target, and receives the radio wave transmitted from the monitoring target transmitter 3 every time the radio wave intensity of the radio wave is received. May be used to acquire the distance to the terminal 1 and exclude the transmitter 3 whose distance from the terminal 1 is away from the monitoring target. Further, the selection unit 12 may select the transmitter 3 that has been monitored continuously for a predetermined number of times from among the transmitters 3 to be monitored as the transmitter closest to the terminal 1.

  The acquisition unit 13 acquires the bed ID (bed identification information) of the bed in which the transmitter 3 is installed from the radio wave of the transmitter 3 determined by the selection unit 12 and transmits the bed ID to the server 2. The patient ID (patient identification information) of the corresponding patient is acquired. Moreover, the bed of this embodiment is a bed for dialysis treatment, and the acquisition unit 13 transmits time information together with the bed ID to the server 2, and the bed of the bed ID performs dialysis treatment in the time zone of the time information. The patient ID of the patient who has been reserved may be acquired from the server 2.

  The storage unit 14 stores the distance information of the monitored transmitter 3 whose distance from the terminal 1 is within a predetermined distance.

  The server 2 transmits various data held by the server 2 to the terminal 1 in response to a request from the terminal 1. The illustrated server 2 includes a control unit 21, a reservation DB (database) 22, and a patient DB (database) 23.

  The control unit 21 receives a patient ID request including a bed ID and time information from the terminal 1, and reserves a patient ID of a patient who is reserved for dialysis treatment in the time information time zone in the bed of the bed ID. Read from the DB 22 and transmit to the requesting terminal 1. Moreover, the control part 21 receives the data request | requirement containing patient ID from the terminal 1, reads the data (for example, dialysis data etc.) regarding the patient of the said patient ID from patient DB23, and transmits to the terminal 1 of a request origin.

  The reservation DB 22 stores reservation information of patients who are to undergo dialysis treatment. Specifically, for each bed (for each bed ID), the patient ID of the assigned patient and the dialysis date and time are stored in association with each other. The patient DB 22 stores patient data such as a patient name, dialysis data related to dialysis treatment, and the like for each patient (for each patient ID).

  As the terminal 1 and the server 2 described above, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as a hard disk, an input device, and an output device can be used. In this computer system, each function of each device is realized by the CPU executing a predetermined program loaded on the memory. For example, each function of the terminal 1 and the server 2 is realized by executing the CPU of the terminal 1 in the case of the program for the terminal 1, and the CPU of the server 2 in the case of the program for the server 2.

  Further, the program for the terminal 1 and the program for the server 2 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, a DVD-ROM, or distributed via a network. You can also.

  The transmitter 3 is a device that transmits radio waves. The transmitter 3 of the present embodiment is a beacon terminal that transmits a BLE (Bluetooth Low Energy (registered trademark)) radio wave, that is, a beacon signal.

  Moreover, the transmitter 3 of this embodiment is installed in each bed of a hospital room and transmits ID information for identifying the bed using radio waves. Specifically, the ID information includes a UUID (Universally Unique Identifier), a Major value, and a Minor value. In the present embodiment, a predetermined value for UUID, a type indicating bed as a Major value, a bed ID (for example, a bed number) of a bed where the transmitter 3 is installed as a Minor value, are previously stored as ID information. The transmitter 3 is set.

  FIG. 2 is a diagram illustrating an area where the radio waves of the transmitter 3 (beacon terminal) can be received.

  Terminals 1A, 1B, and 1C existing in an area 31 within a predetermined distance (r3) from the transmitter 3 receive radio waves transmitted from the transmitter 3 and detect the presence of the transmitter 3. On the other hand, since the terminal 1D whose distance from the transmitter 3 is more than the predetermined distance (r3) cannot receive the radio wave of the transmitter 3, it cannot detect the presence of the transmitter 3.

  In this embodiment, when the terminal 1 receives a radio wave transmitted by the transmitter 3, the terminal 1 calculates (measures) a distance from the transmitter 3 using the radio field intensity of the received radio wave, and according to the calculated distance. Then, the distance to the transmitter 3 is classified into a plurality of levels. In the example shown in FIG. 2, the region 32 where the distance to the transmitter 3 is within r1 is set to “very close (Immediate)”, and the region 33 where the distance to the transmitter 3 is greater than r1 and within r2 is set to “close level”. (Near) ”, and in the region 34 where the distance to the transmitter 3 is greater than r2 and within r3,“ far level (Far) ”.

  FIG. 3 is a diagram showing an example of the arrangement of the transmitter 3 in a hospital room that performs dialysis treatment in the present embodiment. The transmitter 3 is installed in each of the plurality of beds. Moreover, in the example shown in figure, the transmitter 3 is installed in the passage side of each bed, and always transmits a radio wave indicating the bed ID at a predetermined transmission interval. Thus, the medical staff having the terminal 1 moves through the passage and approaches the target bed, so that the terminal 1 can receive the radio waves of the transmitter 3 installed on the approaching bed.

  Next, the operation of the patient identification system of this embodiment will be described.

  FIG. 4 is a sequence diagram showing the operation of the patient identification system. The terminal 1 receives each radio wave transmitted from each transmitter 3 and updates the distance information of each transmitter 3 stored in the storage unit 14 (S11). The distance information update process will be described later.

  And the selection part 12 of the terminal 1 will receive the said terminal 1 using the distance information of each transmitter 3 memorize | stored in the memory | storage part 14, if the patient ID acquisition instruction | indication which the medical staff input is received (S12: YES). The transmitter 3 installed at the closest position is selected (S13).

  The medical staff inputs a patient ID acquisition instruction to the terminal 1 by performing an operation such as touching (tapping) a predetermined button displayed on the display of the terminal 1 or a patient ID input area, for example.

  And the acquisition part 13 of the terminal 1 acquires ID information notified by the electromagnetic wave of the nearest transmitter 3 which the selection part 12 selected (S14). In the present embodiment, the acquisition unit 13 acquires the type (bed) set as the Major value and the bed ID set as the Minor value among the ID information.

  Then, when the type is “bed”, the acquisition unit 13 transmits a patient ID request including the bed ID set to the Minor value to the server 2 (S15). The acquisition unit 13 may transmit a patient ID request including time information to the server 2 together with the bed ID. The time information is the current time when the medical staff does not designate (input) the time, and is designated when the medical staff designates the time.

  When receiving the patient ID request transmitted from the terminal 1, the control unit 21 of the server 2 refers to the reservation DB 22, and sets the time designated by the time information to the bed corresponding to the bed ID included in the patient ID request. The patient ID of a patient who is reserved to perform dialysis treatment in the included time zone is acquired (S16), and the acquired patient ID is transmitted to the requesting terminal 1 (S17).

  When the terminal 1 acquires the patient ID from the server 2, the terminal 1 displays the patient ID on the display of the terminal 1. Further, the terminal 1 receives an instruction from the medical staff and transmits a data request including the acquired patient ID to the server 2 (S18). The data request is for requesting patient data such as a patient name, dialysis data related to dialysis treatment, and the like.

  When receiving the data request transmitted from the terminal 1, the control unit 21 of the server 2 reads out patient data, dialysis data, and the like corresponding to the patient ID included in the data request from the patient DB 23, and requests the read data. It transmits to the original terminal 1 (S19). When receiving data from the server 2, the terminal 1 generates a predetermined dialysis management screen and displays it on the display. Thereby, the medical staff can confirm the information of the patient in the nearby bed.

  FIG. 5 is a diagram illustrating an example of a dialysis management screen displayed on the display of the terminal 1.

  Next, details of the processing of the terminal 1 in S11 of FIG. 4 will be described.

  FIG. 6 is a flowchart showing the process of S11 of FIG. FIG. 6 shows processing when a radio wave is received from one transmitter 3. When radio waves are received from a plurality of transmitters 3, the processing of FIG. 6 is performed for each transmitter 3.

  The receiving unit 11 of the terminal 1 receives radio waves from the transmitter 3 (S31). Thereby, the selection unit 12 of the terminal 1 calculates the distance from the transmitter 3 using the radio wave intensity of the received radio wave, and the level of the distance from the transmitter 3 is any level (see FIG. 2). ) (S32).

  When the acquired level is “very close” (S33: YES), the selection unit 12 extracts the transmitter 3 as a monitoring target and stores the distance information of the transmitter 3 in the storage unit 14. . Note that the transmitter 3 whose acquired level is “very close” means a transmitter 3 in which the distance between the terminal 1 and the transmitter 3 is within a predetermined distance (r1), as shown in FIG. .

  FIG. 7 is a diagram illustrating an example of position information of the monitoring target transmitter 3 stored in the storage unit 14. The selector 12 adds the distance to the transmitter 3 and updates the position information each time it receives a radio wave from the transmitter 3 for the transmitter 3 extracted as a monitoring target.

  When the acquired level is other than “very close level” (S33: NO), that is, when it is “near level” and “distant level”, the selection unit 12 does not set the transmitter 3 as a monitoring target. End the process.

  And the receiving part 11 receives the electromagnetic wave transmitted in the next transmission timing of the transmitter 3, and calculates the distance with the transmitter 3 using the electromagnetic wave intensity of the received electromagnetic wave (S35). Then, the selection unit 12 compares the previous distance stored in S34 with the current distance calculated in S35, and determines whether or not the current distance is greater than the previous distance (S36). That is, the selection unit 12 determines whether or not the terminal 1 is away from the transmitter 3.

  When the current distance is larger than the previous distance, that is, when the terminal 1 is away from the transmitter 3 (S36: YES), the selection unit 12 excludes the transmitter 3 from the monitoring target, The distance information of the transmitter 3 is deleted from the storage unit 14 (S37), and the process ends.

  On the other hand, when the current distance is smaller than the previous distance, or when the previous distance and the current distance are the same (S36: NO), the selection unit 12 stores the distance information of the transmitter 3 in the storage unit 14. Is updated (S38). Specifically, as shown in FIG. 7, the current distance is added to the distance information. If the current distance is smaller than the previous distance, it means that the terminal 1 is approaching the transmitter 3 (that is, the medical staff is moving toward the transmitter 3), and When the previous distance and the current distance are the same, it means that the terminal 1 remains in the vicinity of the transmitter 3 (that is, the medical staff does not move in the vicinity of the transmitter 3).

  Then, the selection unit 12 returns to the process of S35 and repeats the subsequent processes.

  By performing the processing shown in FIG. 6 for each transmitter 3 that has received radio waves, the storage unit 14 of the terminal 1 has a transmitter 3 with a distance of “very close” to the terminal 1. The distance information of the transmitter 3 that the terminal 1 is approaching (including the transmitter 3 that remains close to the terminal 1) is always stored.

  As a result, when the selection unit 12 receives an instruction from the medical staff in S12 of FIG. 4, in S13 of FIG. 4, the selection unit 12 refers to the storage unit 14 and sends the transmitter 3 stored in the storage unit 14 to the nearest transmission. Select as machine 3. When there are a plurality of transmitters 3 stored in the storage unit 14, the selection unit 12 selects the transmitter 3 having the closest latest distance as the transmitter 3 closest to the terminal 1.

  In addition, the selection unit 12 transmits the transmitter 3 (the transmitter 3 to be monitored) whose position information has been continuously updated a predetermined number of times from among the transmitters 3 stored in the storage unit 14 to the terminal 1. It may be selected as the nearest transmitter 3.

  In the terminal 1 of the present embodiment described above, the transmitter 3 that is closest to the terminal 1 is selected using the radio wave intensity transmitted from the transmitter installed in each of the plurality of beds, and the selected transmission is performed. The bed ID of the bed in which the transmitter is installed is acquired from the radio wave of the machine 3 and transmitted to the server 2, and the patient ID of the patient corresponding to the bed ID is acquired from the server 2.

  Thereby, in this embodiment, the medical staff can acquire patient ID of the patient in the said bed, and can identify a patient easily only by approaching the target bed, without inputting patient ID. . Therefore, the medical staff can save the trouble of inputting the patient ID and can simplify the work. That is, it is possible to reduce the work load, work time, and psychological stress of the medical staff and improve the convenience of the medical staff. In addition, it is possible to avoid patient misunderstanding due to an input error of the patient ID of the medical staff.

  Further, the terminal 1 of the present embodiment determines whether or not the distance between the terminal 1 and each transmitter 3 is within a predetermined distance using the radio wave intensity, and the transmitter 1 within the predetermined distance The transmitter 3 that is close to the terminal 1 is selected as the transmitter that is closest to the terminal 1. Thereby, in this embodiment, the patient in the bed which the medical staff intends can be identified with high precision even in a hospital room where many beds are installed.

  Moreover, the terminal 1 of this embodiment transmits time information to the server 2 with bed ID, and acquires patient ID. Thereby, in this embodiment, it is a case where several patients use one bed in dialysis treatment, Comprising: The patient who exists in the said bed can be identified exactly.

  In addition, the terminal 1 of the present embodiment extracts the transmitter 3 whose distance from the terminal 1 is within a predetermined distance as a monitoring target, and receives the radio wave transmitted from the monitoring target transmitter 3 every time The distance from the terminal 1 is acquired using the radio wave intensity, and the transmitter 3 that is far away from the terminal 1 is excluded from the monitoring target. Thereby, in this embodiment, the number of the transmitters 3 to be monitored can be reduced, and the processing load on the terminal 1 can be reduced.

  Also, the terminal 1 of the present embodiment selects the transmitter 3 that has been monitored for a predetermined number of times from among the transmitters 3 to be monitored as the transmitter 3 closest to the terminal 1. As a result, it is possible to eliminate the influence of radio wave reflection, interference and the like, and to identify the patient with higher accuracy.

  While the embodiments of the present invention have been described above, various modifications and changes can be made to the embodiments of the present invention without departing from the spirit of the present invention.

  For example, in the above embodiment, the patient in the bed is identified, but the medical staff using the terminal (tablet terminal or the like) may be identified. In this case, the medical staff carries a tag type transmitter (beacon terminal) by hanging it from the neck. Here, in the transmitter, a predetermined value is set as ID information, a predetermined value for the UUID, a type indicating the staff as the Major value, and a user ID of the medical staff who owns the transmitter as the Minor value. . When the medical staff possessing the transmitter picks up and holds the terminal, the distance from the transmitter possessed by the medical staff is reduced. The terminal performs processing similar to that of the terminal 1 described in the above embodiment, thereby selecting the nearest transmitter (that is, the transmitter of the medical staff holding the terminal), and the selected transmitter transmits. The user ID notified by radio waves is transmitted to the server. By receiving the user ID transmitted by the terminal, the server performs a login process for the medical staff possessing the transmitter.

  As a result, when using a shared terminal, the medical staff can enter the login state without entering login information such as his / her user ID and password, and the terminal can be used. It is unnecessary and can improve the convenience of the medical staff.
