JP6249640B2 - Medical outing notification system, receiver and medical outing notification program - Google Patents

Description

  The present invention relates to a medical outing notification system, a receiver, and a medical outing notification program.

  Various techniques for monitoring the condition of a patient in a hospital are known. As one of the techniques, there is a technique in which a transmitter is attached to a patient, the condition of the patient is measured by the transmitter, and transmitted to a remote display device. Since the patient status is displayed on the display device, a hospital staff such as a nurse can monitor the patient status from a remote location such as a nurse station.

  The transmitter attached to the patient is lightweight and portable so that the patient can move freely. Therefore, the patient may go out of the room where the patient should originally be, and the patient's whereabouts may be lost. In that case, hospital staff spends a great deal of labor and time searching for patients.

  In order to solve this problem, a technique is known in which information indicating the position of a patient is transmitted from a transmitter and monitored by a remote display device in addition to patient biological information (see, for example, Patent Document 1). ). According to this technique, even when the patient has left the room, the location of the patient can be grasped as long as the patient is within a predetermined monitoring area.

Japanese Patent Laid-Open No. 10-248816

  However, with the technique described in Patent Document 1, the patient's whereabouts can be confirmed. However, unless the patient is constantly following the patient's movement by watching the screen, it is immediately confirmed that the patient has gone out of the room. Can't figure out.

  When the patient goes out of the room where he / she should be, the possibility of the patient's whereabouts not being understood increases as the patient goes out of the predetermined monitoring area. Also, if the medical condition suddenly changes while the patient is out of the room, first take the patient to a place where there is a medical device. It is necessary to do. Thus, the hospital staff needs to pay more attention to the patient's condition when the patient is out of the room than when the patient is in the room. Therefore, a system that can immediately grasp that a patient has left the room is desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a medical outing notification system, a receiver, and a medical outing notification program that notify when a patient leaves a predetermined area.

The medical outing notification system includes a plurality of identification information transmitters, a transmitter, and a receiver. The identification information transmitter is installed in each room and transmits unique identification information. The transmitter is carried by the patient so that the identification information can be received, obtains the biological information of the patient, and transmits the identification information that can be received at the position of the patient together with the biological information. The receiver receives identification information and biometric information from the transmitter. The receiver includes a storage unit, a reception unit, and a notification unit. The storage unit stores in advance the unique identification information in association with the room information of each room. The reception unit registers the correspondence between the patient information representing the patient carrying the transmitter and the room information of the location room set when the patient enters the room or changes the room as the room where the patient should be located. Accept. The notifying unit determines whether or not the identification information associated with the room information of the location room is received from the transmitter, and if not received , notifies that the patient is not in the location room.

The receiver includes a reception unit, a storage unit, a reception unit, and a notification unit. The receiving unit is identification information that can be received by a patient so as to be able to receive unique identification information transmitted from a plurality of identification information transmitters installed in each room, obtain biological information of the patient, and can be received at the position of the patient The identification information and the biological information are received from a transmitter that transmits the biological information together with the biological information. The storage unit stores in advance the unique identification information in association with the room information of each room. The reception unit registers the correspondence between the patient information representing the patient carrying the transmitter and the room information of the location room set when the patient enters the room or changes the room as the room where the patient should be located. Accept. The notifying unit determines whether or not the identification information associated with the room information of the location room is received from the transmitter, and if not received , notifies that the patient is not in the location room.

The medical outing notification program causes a computer to execute a reception step, a storage step, a reception step, and a notification step. In the reception step, identification information that can be received by a patient so as to be able to receive unique identification information transmitted from a plurality of identification information transmitters installed in each room, obtain biological information of the patient, and can be received at the position of the patient. The identification information and the biological information are received from a transmitter that transmits the biological information together with the biological information. In the storing step, unique identification information is associated with the room information of each room and stored in advance. In the reception step, registration of correspondence between patient information representing a patient carrying the transmitter and room information of a location room set when the patient enters the room or when the room is changed as a room where the patient should be located is registered. Accept. The notifying step determines whether or not the identification information associated with the room information of the location room is received from the transmitter, and if not received , notifies that the patient is not in the location room.

  According to the present invention, when the identification information associated with the room information of the patient's location room cannot be received from the transmitter, the fact that the patient is not in the location room is notified. Thus, the user can immediately grasp that the patient has gone out of the room, can prevent the patient from missing, and can pay attention to the behavior of the patient.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may be different from the actual ratios.

  FIG. 1 is a diagram showing a schematic configuration of a medical outing notification system, and FIG. 2 is a block diagram showing a schematic configuration of a receiver.

  The medical outing notification system 10 is provided in, for example, a hospital or a nursing facility. Below, the case where the medical outing notification system 10 is provided in a hospital is demonstrated.

  As shown in FIG. 1, the medical outing notification system 10 includes an identification information transmitter 20 (20a, 20b, 20c, 20d), a transmitter 30 (30A, 30B, 30C), and a receiver 40. Each configuration will be described.

(Identification information transmitter 20)
The identification information transmitter 20 is installed in a hospital room in the hospital. Each identification information transmitter 20 is set with unique identification information. The identification information transmitter 20 repeatedly transmits the identification information as a position ID.

  In the example shown in FIG. 1, the identification information transmitter 20a is installed in the room 701, and the identification information transmitter 20b is installed in the room 702. In room 703, an identification information transmitter 20c and an identification information transmitter 20d are installed. In the identification information transmitters 20a, 20b, 20c, and 20d, “100”, “200”, “300”, and “400” are set as the position IDs, respectively.

  Each of the identification information transmitters 20a, 20b, 20c, and 20d transmits a position ID set to the own device in a range as indicated by regions R1, R2, R3, and R4 in FIG. For example, most of the area of room 701 is included in area R1. Therefore, if the user is in the room 701, the position ID “100” transmitted from the identification information transmitter 20a is within a range that can be reached. Similarly, most of the area of room 703 is included in area R3 or R4. Therefore, if it is in the room 703, it is in the range where either the position ID “300” or “400” transmitted from the identification information transmitter 20c or 20d reaches.

  The timing at which the identification information transmitter 20 transmits the position ID may be a random timing within a certain period such as 10 seconds plus or minus 3 seconds. Or it is good also as periodic timings, such as a 10 second interval.

(Transmitter 30)
The transmitter 30 is a device that can be carried by the patient, and is attached to the patient to detect and transmit a biological signal of the patient. Specifically, the transmitter 30 has measurement means (not shown) such as a biological information sensor for acquiring biological information such as an electrocardiogram electrode, and a living body such as a patient's heart rate, respiratory rate, and blood oxygen saturation. Information is detected, and the detected biological information is transmitted by a radio signal.

  The transmitter 30 can further receive the position ID transmitted from the identification information transmitter 20. When the transmitter 30 receives the position ID, the transmitter 30 also transmits the position ID in addition to the biological information.

  When the transmitter 30 receives a plurality of position IDs from the plurality of identification information transmitters 20, the transmitter 30 may transmit the received plurality of position IDs. Alternatively, the transmitter 30 may transmit only the position ID received last in the reception cycle time, for example, 10 seconds. Alternatively, the transmitter 30 may transmit the received position ID having the highest wireless signal strength among the received position IDs.

  A plurality of transmitters 30 are assigned different unique channels so as not to interfere with each other, and each transmitter 30 is identified by the channel. The channels correspond to different frequencies, for example.

  In the example shown in FIG. 1, transmitters 30A, 30B, and 30C are attached to patients (Mr. A, Mr. B, and Ms. C), respectively. For example, Mr. A is located in the room 701 and is in the region R1 where the position ID transmitted from the identification information transmitter 20a reaches. Therefore, the transmitter 30A attached to Mr. A receives the position ID “100” transmitted from the identification information transmitter 20a. The transmitter 30A transmits the received position ID “100” together with the biometric information of Mr. A to the receiver 40. Similarly, the transmitter 30B attached to Mr. B receives the position ID “200” transmitted from the identification information transmitter 20b and transmits it to the receiver 40 together with the biometric information of Mr. B. Similarly, the transmitter 30C attached to Mr. C receives the position ID “400” transmitted from the identification information transmitter 20d, and transmits it to the receiver 40 together with the biological information of Mr. C.

(Receiver 40)
The receiver 40 receives the biological information and the position ID transmitted from the transmitter 30.

  As shown in FIG. 2, the receiver 40 includes a CPU 401, a ROM 402, a RAM 403, a network interface 404, a receiving unit 405, a display unit 406, an operation unit 407, and a storage 408, which are buses for exchanging signals. 409 are connected to each other.

  The CPU 401 performs control of each unit and various arithmetic processes according to programs recorded in the ROM 402 and the storage 408. The CPU 401 functions as a reception unit and a notification unit by executing a program. The ROM 402 stores various programs and various data. The RAM 403 temporarily stores programs and data as a work area.

  The network interface 404 is an interface for communicating with other devices via the network, and standards such as Ethernet (registered trademark) and Wi-Fi, telephone lines, and the like are used.

  The receiving unit 405 receives the signal transmitted from the transmitter 30 and the biological information and the position ID included in the signal. The receiving unit 405 can receive signals transmitted from the plurality of transmitters 30.

  The display unit 406 is a liquid crystal display, for example, and displays various types of information such as the name of the patient, the room where the patient is located, and biological information.

  The operation unit 407 includes a pointing device such as a mouse and a keyboard, and is used for performing various inputs. The operation unit 407 may be an operation key realized as software on the display unit 406 by a touch panel method.

  The storage 408 stores various programs including an operating system and various data as a storage unit. The storage 408 is installed with an application for detecting and notifying a patient going out.

  Further, the storage 408 stores the channel number of the transmitter 30 and the patient information of the patient to whom the transmitter 30 is attached in association with each other. Therefore, when receiving data from the transmitter 30, the receiver 40 can identify which patient's state the received data represents based on the channel number used.

  Further, the storage 408 includes information on the position ID transmitted by the identification information transmitter 20, information relating the room information and the position ID, room information on the patient room and the room where the patient should be, and Are stored in association with each other. Here, the room information is information given to each room in order to identify each room in the hospital, and may be a room number such as “701” or “702”, for example. Alternatively, the room information may be a room name such as “mandarin orange” or “apple” that is used as a name of a room in a child ward. Below, the case where a room number is used as room information is demonstrated. The contents of this information and the registration method will be described below.

  3 is a diagram showing an example of a screen for registering a position ID, FIG. 4 is a diagram showing an example of a screen for registering the association between a room number and a position ID, and FIG. 5 is a room of patient information and a patient's location room It is a figure which shows an example of the screen which performs registration of matching with a number. The screens shown in FIGS. 3 to 5 are displayed on the display unit 406 of the receiver 40. The user can register various information by operating the operation unit 407 while viewing the screen of the display unit 406. Various information registration processing is stored as a program in the ROM 402 or the storage 408 of the receiver 40 and is executed by the CPU 401.

  First, on the screen shown in FIG. 3, the receiver 40 receives registration of the position ID set in the identification information transmitter 20 used in the medical outing notification system 10. The example in FIG. 3 corresponds to the example in FIG. 1, and four values “100”, “200”, “300”, and “400” are registered as position IDs. The registered position ID is stored in the storage 408. This registration is performed when the system is introduced or when the system setting is changed due to a layout change or the like.

  Next, on the screen shown in FIG. 4, the receiver 40 accepts registration of association between the room number and the position ID. In FIG. 3, since four values of “100”, “200”, “300”, “400” are registered as position IDs, the receiver 40 selects the corresponding four radio buttons on the screen shown in FIG. Display as possible. The example of FIG. 4 corresponds to the example of FIG. 1, and the room number “701” is registered in association with the position ID “100” and the room number “702” is associated with the position ID “200”. . In addition, the room number “703” is registered in association with two values of position IDs “300” and “400”. Information relating the room number and the position ID is stored in the storage 408. This registration is performed when the system is introduced or when the system settings are changed due to a layout change in the facility.

  Next, on the screen shown in FIG. 5, the receiver 40 accepts registration of association between patient information and the room number of the patient's location room as a reception unit. The example of FIG. 5 corresponds to the example of FIG. 1, and the patient information of Mr. B and the room number “702” of the room of Mr. B are registered in association with each other. In this screen, the receiver 40 also accepts registration of a message to be displayed on the display unit 406 when Mr. B's outing is detected. Information in which the patient information is associated with the room number of the patient's room and the registered message are stored in the storage 408. This registration is performed when the patient enters the room or when the patient's location is changed.

  Next, the flow of the outing notification process in the medical outing notification system 10 will be described.

  FIG. 6 is a flowchart showing the flow of the outing notification process in the receiver, and FIG. 7 is a diagram showing a display example of the notification in the receiver. The process shown in the flowchart of FIG. 6 is stored as a program in the ROM 402 or the storage 408 of the receiver 40 and is executed by the CPU 401.

  As shown in FIG. 6, the receiver 40 determines whether or not data has been received from the transmitter 30 (step S101).

  When data is not received from the transmitter 30 (step S101: NO), the receiver 40 returns to step S101 and waits until data is received from the transmitter 30.

  When data is received from the transmitter 30 (step S101: YES), the receiver 40 acquires a channel number used by the transmitter 30 and a position ID (step S102). Here, the position ID to be acquired is one that the transmitter 30 has received in advance from the identification information transmitter 20 and transmitted to the receiver 40.

  Subsequently, the receiver 40 selects the patient to which the transmitter 30 that is the data transmission source is attached from the acquired channel number and the information in which the channel number stored in the storage 408 is associated with the patient information. Specify (step S103).

  Subsequently, the receiver 40 determines the patient's location room from the patient information of the patient identified in step S103 and the information in which the patient information stored in the storage 408 is associated with the room number of the patient's location room. A room number is specified (step S104).

  Subsequently, the receiver 40 is associated with the room number of the location room from the room number of the patient's location room identified in step S104 and the information associated with the room number and the position ID stored in the storage 408. The specified position ID is specified (step S105). Here, the position ID associated with the room number of the location room (hereinafter referred to as the location room position ID) is one or a plurality of position IDs.

  Subsequently, the receiver 40 determines whether or not the position ID included in the location room position ID specified in Step S105 is received from the transmitter 30 (Step S106).

  When the position ID included in the location room position ID is received (step S106: YES), the receiver 40 determines that the patient is in a normal state where the patient is not out of the location room, and does not perform notification. The process ends.

  When the location ID included in the location room location ID has not been received (step S106: NO), the receiver 40 determines that the patient is not in the location room, that is, the patient has gone out of the room, and serves as a notification unit. Notification is performed (step S107). For example, as shown in FIG. 7, the notification is performed by displaying a message “You have left the room” registered in the storage 408 in advance in a portion indicating the state of Mr. B on the screen of the display unit 406. Further, at the time of notification, the user may be alerted by sounding an alarm sound or lighting a lamp. It should be noted that in the case of “when the position ID included in the location room position ID has not been received” in the determination process of step S106, when the position ID not included in the location room position ID has been received, The case where the position ID is not set is included.

  Next, a specific example of the outing notification process shown in the flowchart of FIG. 6 will be described.

  FIG. 8 is a diagram illustrating how notification is performed in the receiver.

  In the example shown in FIG. 8, Mr. B has gone out of the room 702 which is the location room. At this time, since Mr. B is in a position where the position ID transmitted from the identification information transmitter 20 does not reach, the transmitter 30B attached to Mr. B receives the position ID transmitted from the identification information transmitter 20. Can not. Therefore, the transmitter 30B transmits only the biological information without transmitting the position ID to the receiver 40.

  When the receiver 40 receives data from the transmitter 30B, the receiver 40 executes the processes of steps S101 to S105 in FIG. First, the receiver 40 specifies that the transmission source of the received data is the transmitter 30B and is data representing the state of Mr. B. Next, the receiver 40 specifies the room number “702” registered as the room where Mr. B is located, and further specifies the position ID “200” associated with the room number “702”.

  Here, the position ID value is not set in the data received by the receiver 40 from the transmitter 30B. Therefore, the receiver 40 does not receive the position ID associated with Mr. B's location room in the process of step S <b> 106 in FIG. 6, and determines that Mr. B has gone out of the location room. As a result, as shown in FIG. 8, the receiver 40 performs notification by displaying a message “I left the room” on the display unit 406 indicating the state of Mr. B.

  On the other hand, Mr. A is located in room 701, which is his own room. The transmitter 30A attached to Mr. A receives the position ID “100” transmitted from the identification information transmitter 20a and transmits it to the receiver 40. When the receiver 40 receives data from the transmitter 30A, the receiver 40 executes the processes of steps S101 to S105 in FIG. The receiver 40 specifies the room number “701” registered as the location room of Mr. A, and further specifies the location room position ID “100” associated with the room number “701” of the location room.

  Here, the position ID “100” is set in the data received from the transmitter 30A. Since the receiver 40 has received the position ID associated with Mr. A's location room in the process of step S106 of FIG. 6, it is determined that Mr. A has not left the location room. Therefore, the receiver 40 ends the process without performing notification.

  In addition, Mr. C is located in room 703, which is his own room. The transmitter 30C attached to Mr. C receives the position ID “400” transmitted from the identification information transmitter 20d and transmits it to the receiver 40. When the receiver 40 receives data from the transmitter 30C, the receiver 40 executes the processes of steps S101 to S105 in FIG. The receiver 40 specifies the room number “703” registered as the room where Mr. C is located, and further specifies the position IDs “300” and “400” associated with the room number “703”.

  Here, the position ID “400” is set in the data received from the transmitter 30C. Since the receiver 40 has received the position ID associated with Mr. C's location room in the process of step 106 in FIG. 6, it is determined that Mr. C has not left the location room. Therefore, the receiver 40 ends the process without performing notification.

  As described above, according to the medical outing notification system 10 of the present embodiment, when the position ID associated with the room number of the patient's location room cannot be received from the transmitter, the notification that the patient is not in the location room is notified. To do. Therefore, the user can immediately grasp that the patient has gone out of the room. This can prevent the patient from missing and pay more attention to the patient's condition.

  The storage 408 of the receiver 40 stores the room ID in association with the room ID. Thus, the user can set the location of the patient by using a value that is familiar to the business, such as a room number, without being aware of the unfamiliar value called the position ID. As a result, the operability for the user is improved and setting errors can be prevented.

  The storage 408 of the receiver 40 can store a plurality of position IDs in association with one room number. As a result, even when a single identification information transmitter cannot cover the entire room in a large room or a room with a complicated shape, this system can be flexibly applied by installing multiple identification information transmitters in one room. it can.

  Further, the receiver 40 can cause the display unit 406 to display an arbitrary message registered in advance for each patient. This makes it possible to display a message including precautions when the patient goes out of the room according to the condition of each patient, and it is possible to appropriately respond to each patient's condition. Become.

(Modification)
In the above embodiment, the example in which the user is notified by displaying a message on the display unit 406 of the receiver 40 has been described, but the present invention is not limited to this. Notification may be performed in a device other than the receiver 40. A specific example will be described below.

  FIG. 9 is a diagram illustrating how notification is performed at a terminal carried by a nurse.

  In the example shown in FIG. 9, since Mr. B is outside the location room, a message is displayed on the display unit 406 of the receiver 40 as in the example of FIG. 8. Furthermore, the receiver 40 accesses a server or switching office on the network via the network interface 404 and displays it on the display unit 406 on the mobile terminal 50 carried by a hospital staff such as a nurse. Send a similar message. The mobile terminal 50 is a mobile phone, a PHS, a smartphone, a tablet PC, or the like, and can be diverted from what a nurse originally uses for business communication in a hospital. The mobile terminal 50 displays the received message on the screen or guides it by voice to notify the nurse that the patient has gone out of the room. In addition, a message is transmitted not only to the mobile terminal 50 carried by the nurse but also to another device installed at a location different from the receiver 40, and notification that the device has moved out of the room where the nurse is located. May be.

  Thereby, even when the nurse is not near the receiver 40, it can be immediately grasped that the patient has gone out of the room. As a result, when the patient goes out of the room, the nurse can deal with it more reliably and quickly.

  In the above-described embodiment, the association between the room number and the position ID is described as associating the room number of one room with the position ID of the identification information transmitter 20 installed in the room. However, it is not limited to this. The room number of one room may be associated with the position ID of the identification information transmitter 20 set outside the room. A specific example will be described below.

  As shown in FIG. 1, the range in which the identification information transmitter 20 transmits the position ID does not completely match the area of each room. Therefore, it is conceivable that the position ID transmitted by the identification information transmitter 20 installed in a certain room reaches, for example, the adjacent room. Depending on the room structure and the like, it is also assumed that the transmitter 30 frequently receives the position ID of the identification information transmitter installed in the adjacent room. Specifically, this is a case where the transmitter 30A attached to Mr. A in the room 701 receives the position ID “200” transmitted from the identification information transmitter 20b installed in the room 702 which is the adjacent room. . In such a case, the receiver 40 may register the room number “701” in association with the position ID “100” in addition to the position ID “100”. Thereby, it is possible to prevent the notification that Mr. A has left the room even though Mr. A is in the room 701 in the above case. In this case, when Mr. A is in room 702, notification will not be made, but when Mr. A enters the hallway from room 701, notification will be given, and Mr. A will be in room 701 or next to 702. Since it can be grasped that it is in the room, the object of the present invention can be achieved without problems.
