  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. The following embodiment is an example to which the patient condition determination apparatus of the present invention is applied, and it goes without saying that the contents of the invention are not limited to the present embodiment.

[1. Entire system]
First, the entire system in the present embodiment will be described. FIG. 1 is a diagram for explaining the whole of a patient state display system 1 incorporating a patient state determination device.

  First, the patient P lies on the mattress 5 placed on the bed 3. And the state detection apparatus 20 is provided in the bed.

  The state detection device 20 is a device capable of continuously acquiring patient's biological information, and acquires values such as the patient's weight, body movement, blood pressure, and blood sugar level. As an example of the state detection apparatus 20, as shown, for example in FIG. 1, it may be provided between the bed 3 and the mattress 5, and a state may be detected by providing a sensor in a patient. Further, it may be configured to be directly provided to the bed apparatus (for example, using a load related to an actuator). The state detection device 20 is connected to the patient state display device 10.

  The patient state display device 10 has a function of a patient state determination device, and is connected to the state detection device 20, connected to the measurement device 60, or connected to another server device etc. via a network. Being done. Further, by holding the authentication card 65 over the patient status display device 10, it is possible to realize the authentication process (login process).

  The login is performed by a person having the authority such as staff (nurse, doctor, care staff). By logging in, it is possible to confirm the biological information value and the content of the alarm, or to register in an electronic medical record. Further, the authority may be set for each login user, and the range in which the user can operate may be changed.

  For example, a server 30, an electronic medical record server 40, a terminal device 50, and a portable terminal device 55 are connected to the network.

  The server 30 is a server that provides various services, and may be connected to a LAN in a hospital or a facility, or may be provided outside via the Internet.

  The electronic medical chart server 40 is a server that stores electronic medical chart information about a patient. Usually, it is connected to a network in a hospital or facility, but for example, an external cloud server may be used.

  The terminal device 50 is a terminal device for connection in a nurse station or a management room, and can recognize the status of the patient status display device 10 even if it is separated. In addition, the mobile terminal 55 can be connected wirelessly to, for example, a LAN, so that a nurse, an assistant staff, etc. can easily confirm the information of the patient status display device 10.

  The patient status display device 10 will be described in detail with reference to FIG. The patient status display device 10 is configured to include a display terminal 1000 and a connection device 2000. The display terminal 1000 is, for example, a tablet type display terminal, and displays various types of information and accepts input of various operations. The display terminal 1000 may be a dedicated terminal constituting the patient status display device 10, or may be realized by installing an application (program) on a general-purpose tablet terminal.

  The connection device 2000 is a device for connecting the display terminal 1000 and various devices. That is, it plays a hub role of various devices. For example, as shown in FIG. 1, by being connected to the state detection device 20, it is possible to continuously obtain patient's biological information, receive biological information from the measuring device 60 (for example, a thermometer), It is also possible to receive biological information from a device worn by the patient (e.g. a measuring device of a watch-like wearable). In addition, by connecting the authentication card 65 to, for example, the communication unit 220, an authentication process (for example, authentication of a patient or authentication of staff) can also be realized. As an authentication method, NFC is used as an example of the short distance wireless communication in the present embodiment, but authentication may be performed using another method such as a bar code, an infrared ray, or an IC tag, for example. Good.

  Further, a notification unit 260 is provided, and it is possible to notify, for example, when an error occurs. Furthermore, it is also possible to connect to a server device via a LAN (a LAN may be a wired LAN or a wireless LAN). The notification unit 260 may not normally be visible, and may be configured to be turned on (displayed) only when notifying. Further, instead of the display, for example, notification may be made by using a sound such as an alarm sound, a warning sound, or a voice, or may be generated by using light.

  Although the display terminal 1000 is described as being placed on the connection device 2000 in this embodiment, the display terminal 1000 and the connection device 2000 may be used separately. For example, the display terminal 1000 may be taken out and used at another place, or the connection device 2000 may be incorporated in a bed apparatus and the display terminal 1000 may be used separately.

[2. Functional configuration]
Subsequently, the functional configuration in the present embodiment will be described using the drawings. FIG. 3 is a diagram for explaining the functional configuration of the display terminal 1000 and the connection device 2000 in the patient status display device 10.

[2.1 Display terminal]
First, the functional configuration of the display terminal 1000 will be described. The display terminal 1000 is configured to include a control unit 100, a storage unit 110, a device communication unit 150, an operation unit 160, a display unit 170, and a LAN communication unit 180.

  The control unit 100 is a functional unit for controlling the entire display terminal 1000. The control unit 100 implements various functions by reading and executing various programs stored in the storage unit 110, and is configured by, for example, a CPU (Central Process Unit).

  The storage unit 110 is a functional unit in which various programs necessary for the operation of the display terminal 1000 and various data are stored. The storage unit 110 is configured of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  The storage unit 110 also stores biometric information 112, individual electronic medical record data 120, and an alarm threshold table 122, and as a program, a main program 132, an alarm program 134, and a patient state display program 136. , And the electronic medical record registration program 138 are stored.

  The living body information 112 stores continuous living body information 114 which is living body information continuously detected from the state detecting device 20, and measurement living body information 116 received from the measuring device 60 at an arbitrary timing. In addition, it is also possible to use manual input or diversion input of continuous biometric information values as required.

  Here, an example of the data structure of the continuous biometric information 114 is shown in FIG. The continuous living body information 114 of the present embodiment stores the value of living body information detected from the state detection device 20 and the value of living body information whose state can be detected from other patients.

  That is, they are stored based on continuously detectable values. For example, as a value corresponding to the measurement date (for example, "2015/05/16 20:00") and the type of biological information, the pulse rate (for example, "126") and body temperature (for example, "37.2") And a respiratory rate (for example, "15") and SpO2 (for example, "99") are stored. That is, the continuous biometric information 114 can obtain predetermined measurement values any time. The continuous biometric information 114 may be acquired from the state detection device 20 or from a detection device provided in the bed 3. Also, various sensors may be provided on the patient's body for acquisition.

  And various acquired biometric information can be put together and managed as continuous biometric information. The values of these biological information are different depending on the items to be detected as necessary (for example, when using only the body movement detection sensor, body movement state, sleep state, patient posture (getting up, staying, wake up), Pulse rate, respiratory rate are detected as continuous biological information).

  The measurement biological information 116 stores biological information received from an external measurement device such as a thermometer, a sphygmomanometer, or a body fat gauge. For example, as shown in FIG. 5, as measurement biological information 116 of the present embodiment, for each reception date (for example, “2015/05/16 20:00”) and each type of biological information (for example, “body temperature”) , And its value (for example, "37.2") is stored. Also, for example, the highest blood pressure (for example, "159") and the lowest blood pressure (for example, "98") are stored.

  Further, the detected continuous living body information 114 and the measured living body information 116 may be stored for a predetermined period. As the stored period, for example, data for one day or three days is stored. Further, the continuous biological information 114 and the measurement biological information 116 may be stored in the server 30.

  The individual electronic medical record data 120 stores electronic medical record data of an individual patient. A collection of the electronic medical record data of the individual patient is stored in the electronic medical record server 40. The data structure of the individual electronic medical record data 120 is the same as that stored in the electronic medical record server 40, and thus the details will be described later. That is, in addition to patient information, continuous biometric information at the time of registration, measurement biometric information, and the like are registered.

  Although the present embodiment is described as being stored in the storage unit 110, data of the electronic medical record server 40 may be used directly. In this case, the individual electronic medical record data 120 may not be stored in the storage unit 110.

  The alarm threshold table 122 stores alarm thresholds for various types of biological information. When the value of the measured (received) biological information exceeds the alarm threshold, notification is performed or error processing is performed. The alarm threshold may be set in advance or may be set arbitrarily.

  An example of the alarm threshold value table 122 is shown in FIG. As shown in FIG. 6, alarm thresholds of the upper limit value and the lower limit value are stored for each biological information. Also, a plurality of alarm thresholds can be stored depending on the type of alarm. Further, in the present embodiment, the alarm threshold stores two levels of caution level and warning level.

  For example, for “pulse” which is one of the biological information, a threshold of the pulse rate (attention level, threshold in a range to be a warning level) is stored as the biological information value. The attention level is stored as "110" and the warning level is stored as "130" as the upper threshold. Further, as the lower threshold, the attention level is stored as "60" and the warning level is stored as "30".

  For example, when the pulse rate is 130 or more or 30 or less, it can be determined that it is included in the range of the warning level. In addition, when the pulse rate is “110 or more and less than 130” or “greater than 30 and 60 or less”, it can be determined that it is included in the caution level range. Note that the threshold may be exceeded (for example, the pulse rate in the warning level range may be greater than 130 or less than 30).

  In the present embodiment, for convenience of explanation, the caution level and the warning level are described in two steps, but it goes without saying that a more range may be set.

  The patient status identification information 124 is information for storing the status of the patient. The patient state identification display described later is performed using the patient state identification information. In the present embodiment, patient status identification information determined based on patient status identification information (section patient status identification information) determined based on patient biometric information of a section from the logout to the present and patient status identification determined based on current patient biometric information Information (current patient status identification information) is stored.

  Here, the states of “normal”, “attention” and “alert” are stored in the patient state identification information. The normal state is when the patient's biometric information value falls within the alarm threshold range (a range that is neither caution level nor warning level). Further, “attention” is a case where there is a biological information value within the threshold range of the attention level among the biological information values of the patient. Similarly, “Warning” is a case where there is a biological information value within the threshold range of the warning level among the biological information values of the patient.

  Also, although the section patient state identification information is determined based on the biometric information value at the time from the previous logout to the present in this embodiment, for example, based on the biometric information value from the last logout to the previous login time. Further interval patient condition identification information may be further stored.

  In the present embodiment, if any one of the biological information values is applicable, the patient state identification information changes, but when a plurality of biological information values become the attention level or the warning level, the patient state The identification information may be updated. Further, the patient state identification information is not limited to one, and may be stored for each biological information or for each predetermined group. For example, as predetermined groups, continuous living body information and measurement living body information may be divided, and patient state identification information based on the state of each patient may be determined and stored.

  Further, the control unit 100 can read out the programs stored in the storage unit 110 to realize various functions. Specifically, the main function reads out and executes the main program 132, and the alarm function reads and executes the patient status display program 136 by reading and executing the alarm program 134. The electronic medical record registration function is realized by reading and executing the electronic medical record registration program 138 as the function.

  The device communication unit 150 is a functional unit for communicating with a device communication unit 250 described later. In the present embodiment, for example, connection is performed by USB and communication is performed. For example, another general connection method or wireless connection (such as Bluetooth (registered trademark) or wireless LAN) may be used. You may Further, communication may be performed by providing a dedicated connection interface.

  The operation unit 160 is a functional unit that receives an operation input from a user, and may be, for example, a software key realized by a touch panel, or an input device such as a keyboard or a mouse. Also, voice input may be used.

  The display unit 170 is a functional unit that displays various types of information to the user and performs notification processing. For example, it is realized by a liquid crystal display or the like. Also, it may be realized by a touch panel in which the operation unit 160 and the display unit 170 are integrally formed.

  The LAN communication unit 180 is an interface unit connectable to the LAN. It is configured by a NIC or the like for connecting to Ethernet (registered trademark). The LAN communication unit 180 may be provided in the connection device 2000. In this case, the data to be transmitted is once transmitted to the connection apparatus 2000 via the apparatus communication unit 150 (250) and then transmitted to the network. In addition, in order to connect to a LAN, it may be connected by wire or may be connected by wireless.

[2.2 Connection Device]
Subsequently, the functional configuration of the connection device 2000 will be described. The connection device 2000 includes a control unit 200, a storage unit 210, a communication unit 220, an interface unit 230, a device communication unit 250, and a notification unit 260.

  The control unit 200 is a functional unit for controlling the entire connection device 2000. The control unit 200 realizes various functions by reading and executing various programs stored in the storage unit 210, and is configured by, for example, a CPU (Central Process Unit).

  The storage unit 210 is a functional unit in which various programs necessary for the operation of the connection device 2000 and various data are stored. The storage unit 210 is configured of, for example, a semiconductor memory, a hard disk drive (HDD), or the like.

  The communication unit 220 is a functional unit for communicating with another device or an authentication card. For example, NFC (Near Field Communication) communication can be performed as near field communication. In the case of NFC communication, an authentication process is performed by holding the authentication card 65. When the measuring device 60 has the NFC communication function, holding the measuring device 60 enables reception of biological information via the connection device 2000. The measuring device 60 may be, for example, a device such as a smartphone or a wearable terminal device such as a watch.

  Further, it goes without saying that any method such as Bluetooth (registered trademark), TransferJet (registered trademark), ZigBee (registered trademark), or RFID may be used as the communication unit 220, for example. Also, a LAN (wireless LAN, wired LAN) or the like may be used.

  The interface unit 230 is a functional unit for communicating with another device. For example, it is provided as a functional unit for connecting to the state detection device 20. The interface to be connected may be realized by a dedicated interface or may be realized by a general-purpose interface such as USB or RS-232C.

  The device communication unit 250 is a functional unit for the display terminal 1000 and the connection device 2000 to communicate via the device communication unit 150 described above. For example, it may be connected using USB etc., and may be connected via LAN. In addition, although this embodiment divides and demonstrates the structure of the function of each communication part on account of description, you may be comprised by one. That is, when all communication is performed by Bluetooth, the device communication unit 250, the communication unit 220, and the interface unit 230 are configured by one functional unit.

  The notification unit 260 is a functional unit that operates when the connection device 2000 executes notification processing. For example, if an error display is to be performed, that is notified. As a means to notify, any method such as sound, light, display, and vibration can be considered.

[2.3 Electronic medical record server]
Subsequently, the functional configuration of the electronic medical record server 40 will be described with reference to FIG. The electronic medical record server 40 includes a control unit 400, a communication unit 410, and a storage unit 450.

  The control unit 400 is a functional unit for controlling the entire electronic medical record server 40. The control unit 400 realizes various functions by reading and executing various programs stored in the storage unit 450, and is configured by, for example, a CPU (Central Process Unit) or the like.

  The communication unit 410 is an interface unit for connecting to a network. For example, it is configured by a NIC connectable to Ethernet. Communication can be performed with another device via the communication unit 410.

  The storage unit 450 is a functional unit in which various programs necessary for the operation of the electronic medical record server 40 and various data are stored. The storage unit 450 is configured of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  In addition, the electronic medical record data 452 is stored in the storage unit 450. An example of the electronic medical record data is shown in FIG. Patient information is stored in the electronic medical record data. For example, as shown in R100 of FIG. 8, the patient information, basic information such as patient's name, name, etc. (R102), pictogram, and measured biological information (biological information value) (R104) are stored for each patient.

  Here, the caution information is information for calling attention to convey the condition of the patient to a medical worker, a helper, and the like and a specialist. For example, information related to alerting (prohibition of nose bite etc.), and risk assessment, chewing assessment, fall risk assessment and the like are stored. These pieces of information may be managed by a flag, or may be managed by characters, icons, pictures, and the like.

  Also, pictogram information may be stored to make it easier to understand. Pictograms are based on information about daily life. By displaying the pictogram, it is possible to provide safety and security by being able to take care of the patient even if the person accidentally happened. In this way, as pictogram information, information that provides patient status to many people, attention information transmits information on patient status to specialists.

[3. Screen (state) transition diagram]
Subsequently, the flow of the entire system in the present embodiment will be described using the screen transition diagram (state transition diagram) of FIG.

  First, when the system is activated, it is determined whether an alarm state exists, that is, each biometric information value exceeds (or falls below) an alarm threshold. And an alarm screen (P100) is displayed as needed. Although this alarm screen can confirm that a problem has occurred, the contents of the error are not displayed until the login. This makes it possible to prevent the display of errors that should not be displayed to the patient or family.

  The alarm screen is displayed also at system startup such as when the power is turned on, but it may be determined whether or not the alarm state is required. When an alarm state occurs, the screen may transition to an alarm screen as an interrupt process.

  Subsequently, a patient status display screen (P102) is displayed as the main status. On this screen, nameplate information, pictogram information, caution information, an error condition and the like are displayed as basic information of the patient. In this way, it is possible to display necessary information for medical staff such as nurses and doctors, assistants, and family members who are assisting.

  The patient status display screen (P102) does not display detailed information, as the patient and the family in the hospital can be seen as well as a third party who visits the site. If necessary, authentication processing is performed, and login is performed to switch to the login screen (P104). It is possible to transition to various screens from the login screen. For example, a patient information display screen (P 114) capable of displaying patient information, a biological information display screen (P 106) displaying biological information values, a graph display screen (P 108) capable of displaying a history of biological information values It is possible to switch to the electronic medical record registration screen (P110) for registering the biometric information value in the electronic medical record.

  Furthermore, it is possible to switch to an alarm setting / history screen (P116) for setting conditions to be in an alarm state, and a reminder screen (P112) for setting what should be done next (for example, an instruction for medication etc.).

  As described above, according to the present embodiment, it is possible to centrally display information on a patient, and it is possible to display appropriate information by switching the screen as necessary. In addition, it is possible to centrally manage information on patients by centrally acquiring information of a plurality of measuring devices and registering them in an electronic medical record.

[4. Description of each process]
Subsequently, each process in the present embodiment will be described using the drawings.

[4.1 Main processing]
The main processing in the present embodiment will be described with reference to FIG. The main process is a process implemented by the control unit 100 reading and executing the main program 132 stored in the storage unit 110.

  First, it is judged whether or not it is in the alarm state (step S102). Specifically, each vital value is compared with an alarm threshold to determine whether the alarm threshold is exceeded or less than the alarm threshold, and it is determined whether an alarm should be issued. Then, when it is necessary to issue an alarm, alarm processing is executed (step S102; Yes → step S104, FIG. 10).

  Whether or not the alarm threshold is exceeded differs depending on the type of biological information. In addition, there are also cases where both are determined by the determination criteria (that is, it is determined whether or not the vital value is within a predetermined range).

  Subsequently, a patient state is determined, and a patient state display process of displaying the patient state based on the determined content is executed (step S106, FIG. 11). Here, if login authentication is not performed (or if login fails), the process is repeatedly executed from step S102 (step S108; No → step S102).

  Here, when the login authentication is correctly performed (step S108; Yes), a staff screen which is a login screen is displayed (step S110). The staff screen is a screen on which various processes can be selected. Here, when the stuffing process is selected (step S112; Yes), the process is executed according to the selected stuffing process (step S114). In addition, each process performed here is mentioned later.

  If the staff processing is not selected (step S112; No), or if the logout is not executed even after the staff processing is performed, the login state continues and the processing is repeatedly executed (step S116; No → step S110). ). On the other hand, when logout is executed, the user is logged out, and the process is repeatedly executed from step S102 (step S116; Yes → step S102).

  Here, the selected staff processing is processing corresponding to P106 to P116 described in the screen transition diagram of FIG. 9. The process will be described using a process flow and a screen example.

[4.2 Alarm processing]
Alarm processing will be described with reference to FIG. The alarm process is a process corresponding to P100 in FIG. 9 (step S104 in FIG. 10), and is a process implemented by the control unit 100 reading out and executing the alarm program 134 stored in the storage unit 110. .

  First, it is determined whether there is a device connection error (step S202). Here, if there is a connection error of the device, the output of the device error is displayed (step S202; Yes → step S204).

  Subsequently, it is determined whether there is biological information to be in an alarm state (Step S202; No → Step S206 or Step S204 → Step S206). Specifically, each biological information value is compared with an alarm threshold to determine whether or not it is in an alarm state. Then, when there is a value of the biological information to be in the alarm state (step S206; Yes), the notification process is executed (step S208).

  As an example of the notification process, the notification unit 260 performs the notification process, and the display unit 170 displays an alarm screen. At this time, the detailed information is not displayed unless logged in (after being authenticated).

  Although the alarm processing has been described as being executed in step S104 of FIG. 10, the alarm processing may be confirmed at predetermined time intervals and executed as interrupt processing.

  As described above, when there is biological information to be in an alarm state, it is possible to output an alarm by performing notification processing. In addition, even when there is a device connection error, it is possible to output a device error as one of the alarms. The device connection error may be output as another method or may not be output.

  Further, the contents of the alarm may be notified to the terminal device 50, the portable terminal device 55, and the like. In this case, for example, the notification destination may be changed or the content of the notification may be changed according to the caution level or the warning level.

  For example, for each patient, a table is stored that stores how to report in association with the patient's condition and the type of biological information. At this time, as the notification setting, “not notice” which is not notified, “notice” notified when the attention level is given as the notification level, and “warning” which is notified when the warning level is stored. Also, depending on the type, "ON" or "OFF" may be set simply as if, for example, the user has left the bed.

  Also, the notification destination may be determined in advance in response to the notification setting. For example, “the mobile terminal device of the holding nurse” and “PC” in the nurse station etc. are set as the first notification destination, and “the mobile terminal device of the holding nurse” as the second notification destination, “PC In addition to the above, it is assumed that the “mobile terminal device of the doctor in charge” is decided.

  In this case, when the notification setting is "ON" and "attention", the first notification destination is notified. In addition, when the notification setting is "warning", the second notification destination is notified. Further, in the present embodiment, the “serving nurse” and the “doctor in charge” are extracted from the electronic medical record. In addition, you may set as report destination information separately from an electronic medical record.

  As described above, notification of contents according to the notification setting may be performed on the notification destination set in advance. In addition to being set for each patient, a common notification destination may be set. For example, it is assumed that a rapid response team is set as an emergency call destination common to all patients. In this case, for example, when the patient's biological information value exceeds a threshold having an emergency, or when a plurality of warning level states occur, a setting may be made to notify an emergency notification destination.

  In addition, the notification setting is set to notify in the case of the caution level and the warning level, but is set to each level or higher. For example, when the attention level is set, the first notification destination is notified when the biological information reaches the attention level, and the second notification destination is notified when the warning level is reached. . That is, the attention level includes the warning level. In addition, it is good also as reporting only a caution level by setting.

[4.3 Patient status display processing]
[4.3.1 Flow of processing]
The patient status display process will be described with reference to FIG. The patient state display process is a process corresponding to P102 in FIG. 9 (step S106 in FIG. 10), and is realized by the control unit 100 reading out and executing the patient state display program 136 stored in the storage unit 110. Processing.

  First, the individual electronic medical record data 120 is read out (step S302). In addition, before reading out the data of the electronic medical record, the authentication process of the patient may be executed to read out the data of the authenticated patient.

  Subsequently, a nameplate area is created from the basic information and medical care information included in the individual electronic medical record data 120 (step S304), and a pictogram area is created from the caution information and the pictogram set (step S306). .

  Specifically, the nameplate area (nameplate information on the display screen is displayed from the basic information such as the name, room number, and the attending physician stored in the individual electronic medical record data 120 synchronized with the electronic medical record data 452 of the electronic medical record server 40 Area is created.

  In addition, a pictogram display is created on the basis of general caution information for patients and assistants stored in the individual electronic medical record data 120.

  Subsequently, a warning area based on the warning information is created (step S308), and if there is error information, error information is generated (step S310). Here, the alert information displayed in the alert area is created on the basis of information for alerting an expert such as a medical worker or an assistant. Therefore, the area is created in a state where the contents can not be understood only by the medical staff such as the patient and the family. In addition, although the error information includes information on an alarm, the area is created in a state where the contents are not understood only by the medical staff such as the patient and the family.

  Then, a patient status display screen is generated and displayed in each of the areas created in the above-described steps (step S312).

[4.3.2 Patient state identification display process]
Subsequently, a patient state identification display process is executed, and the patient state identification display is performed on the patient state display screen (step S314). Here, the patient state identification display process will be described with reference to FIG.

  First, when the logout process is performed (step S352; Yes), the patient state information currently stored is cleared once (step S354). Then, continuous biometric information and measured biometric information are received (input) (step S356).

  When continuous living body information or measurement living body information is received, the current patient state (current patient state) is determined (step S358). Here, the current patient state is determined to be any one of "warning", "attention" and "normal" based on all the received biological information. Specifically, "CAUTION" if any biometric information value is included in the caution level of the alarm threshold, and "WARNING" if any biometric information value is included in the alert level of the alarm threshold. It is determined.

  Subsequently, the interval patient state is updated (steps S362 to S370). Specifically, first, if the section patient state is "warning", "warning" is maintained as it is (step S362; Yes).

  Subsequently, if the current patient state is "Warning" if the section patient state is other than "Warning", the section patient state is set to "Warning" (Step S362; No → Step S364; Yes → Step S366). That is, if the current patient status is "Warning" when the interval patient status is "Caution" and "Normal", the interval patient status is "Warning".

  If the current patient state is "attention" when the section patient state is "normal", the section patient state is "attention" (step S362; No → step S364; No → step S368; Yes → step S370). That is, when the section patient state is "normal", if the current patient state is "attention", the section patient state is "attention". When the section patient status is "attention", when the current patient status is "normal" and "attention", the status of "attention" is maintained as it is (step S362; No → step S364; No → step S368; Yes → step S370).

  Also, if the current patient state is "normal" and the section patient state is "normal", the section patient state is maintained as it is "normal" (step S362; No → step S364; No → step S368; No).

  As described above, when the patient state is in a state of higher importance such as “warning”> “attention”> “normal”, the interval patient state is updated in the state. In addition, once the state of high importance is reached, the state is maintained until it is cleared next (for example, until the timing of the next login).

  Then, the patient state identification display is updated based on the patient state (interval patient state, current patient state) (step S372). This allows the staff to easily confirm the current patient state and the worst state from the previous logout to the present.

  Then, the process is repeatedly executed from step S356 until the login process is performed again (step S374; No → step S356).

  Here, an outline of the operation of the patient state identification display will be described with reference to FIG. FIG. 14A is an example of the identification display of the patient state displayed on the screen. An identification display based on the interval patient state is displayed in M102, and an identification display based on the current patient state is displayed in M104. In the present embodiment, in consideration of visibility, the identification display M104 is displayed larger, but the size may be the same, or may be another shape or position.

  FIG. 14 (b) shows an example of identification display of each patient state. For example, M110 indicates normal, M112 indicates caution, and M114 indicates a warning. Note that this display may be changed according to the color, the movement, or the shape. For example, in the case of color, normality may be displayed as "white", attention as "yellow", and warning as "red".

  The operation will be briefly described with reference to (c) to (e) of FIG. In the following description, it is assumed that the previous logout time is t1 and the current time point is t2.

  In FIG. 14 (c), the patient state is "normal" at time t1, but once it becomes "warning" state, then it shifts to "attention" state and reaches t2.

  In this case, the identification display M102 as the section patient state is displayed in the state of "Warning" since it is once "Warning" after t1. Further, since the present (t2) is in the state of "attention", the identification display M104 is the identification display of "attention".

  In (d) of FIG. 14, the patient state is in the “attention” state at time t1, but (t2) is in the “normal” state at present. In this case, the identification display M102 as the section patient state is an identification display of the state of "attention". In addition, since the identification display M104 is in the “normal” state at time t2, identification display of “normal” is performed.

  FIG. 14E is a diagram when the patient state is “normal” at time t1, but transitions to “attention” and “alert” on the way. Even now (t2), it is in the state of "warning". At this time, the identification display M102 indicating the section patient state is "warning", and the identification display M104 indicating the current patient state is also "warning".

  Although two identification displays are described in FIG. 14 for convenience of explanation, a plurality of identification displays may be provided correspondingly. For example, not only the identification display of the patient state (entire) described above, but also the identification display based on only the continuous biological information may be performed. In addition, special identification display may be performed in association with predetermined biological information (for example, respiratory rate etc.).

[4.3.3 Screen Example]
It continues and demonstrates using the example of a screen at the time of this processing being performed. FIG. 15 is an example of the patient status display screen W200. On the display screen W200, as the name plate information, the names of the patient and the names of the attending physicians are displayed in the regions R202 and R204. These items are appropriately selected and displayed from patient information registered in the electronic medical record.

  In addition, a pictogram or the like is displayed in the region R206 as a pictogram region. Furthermore, in the area R208, attention information is particularly displayed from among the attention information. The alert information is a display that can be understood only by experts such as medical staff and staff at a nursing home.

  Also, R 210 reports that an error has occurred. Here, in order to display the error content, it is necessary to execute an authentication process and switch to another screen. By this, it is possible to prevent a non-professional person such as a medical worker or an assistant from confirming an error.

  Further, the operation / state of the state detection device 20 may be displayed on the display screen W200. For example, as shown in the region R212, the state may be displayed. In addition, the connection state of the sensor is also displayed. This makes it possible to grasp that the sensor is not connected or can not be used at a glance.

  In addition, patient status identification display is performed. In FIG. 15, the identification display as the interval patient state is displayed in M200, and the identification display of the current patient state is displayed in M202. The patient status identification display can be performed in various manners. For example, an underline may be displayed under the patient name, and identification display may be performed by color or thickness of a line, or an icon may be separately displayed. .

  In the present embodiment, the patient state identification display is performed on the entire living body information including continuous living body information and measured living body information, but for example, continuous living body information and measured living body information may be separately displayed. Alternatively, the information may be displayed separately for each piece of biological information, such as separately displaying only respiration as the biological information.

[4.4 Biological Information Display Processing]
Subsequently, the biological information display process will be described. The biological information display process is a process corresponding to P106 in FIG. That is, it is processing of displaying biological information values based on the electronic medical record data of the patient.

  FIG. 16 shows a display screen W300 as a screen example when this processing is executed. On the display screen W300, biometric information values are displayed for each piece of biometric information. Further, in the area R302, the date and time when the displayed biological information value is registered is displayed.

  Furthermore, an alarm threshold is displayed in the area R 304 so as to be easily understood next to the biological information value. That is, the alarm threshold is displayed so that the range of the caution level and the range of the warning level become clear.

  In addition, the displayed biological information value may be configured to change in the background when it is in the range of the caution level and the warning level. For example, R306 displays "126 bpm" as a pulse rate. Since this biometric information value is included in the attention level, the background is identified and displayed in the attention level color (for example, yellow).

  Further, various information may be identified and displayed together with the biological information. For example, the display of R308 is identified and displayed that the pulse sensor is ON (that is, the pulse rate can be acquired as continuous biometric information).

  In addition, R310 is a display for prompting a medical staff, a care staff, etc. to be alerted. For example, it is possible to identify and display the biometric information that has a problem between the previous logout and the time of the current login. Thereby, for example, when the patient status identification information is "attention", it is possible to confirm that there is a problem in breathing by the staff logging in.

[4.5 Graph display process]
Subsequently, graph display processing will be described. The graph display process is a process executed at P108 of FIG. That is, it is a process of displaying the transition of the biological information registered in the electronic medical record in a graph.

  FIG. 17 shows a display screen W400 as a screen example when this processing is executed. The display screen W400 displays the transition of each biological information value. And the area | region of an alarm threshold value is also displayed on the graph of each biometric information. This makes it possible to easily confirm when there is an abnormality in the biometric information.

  In addition, when one piece of biological information is selected while this graph is displayed, a graph in which only the biological information is displayed may be displayed.

[4.6 Electronic medical record registration process]
[4.6.1 Flow of processing]
Subsequently, an electronic medical record registration process for registering biological information in an electronic medical record will be described with reference to FIG. The electronic medical record registration process is a process realized by the control unit 100 reading out and executing the electronic medical record registration program 138 stored in the storage unit 110.

  First, patient information is read (step S402), and biological information of the patient is read from the individual electronic medical record data 120 (step S404). The type of biological information called here, the alarm threshold value, and the like may be read out based on the basic information of the patient (for example, the ID of the patient) or the like, or may be set commonly.

  Subsequently, continuous living body information is received from the state detection device 20, and the value of the received living body information is displayed (step S408). Here, if there is an input instruction for biometric information (step S410; Yes), a biometric information value is manually input (step S412).

  At this time, when the biometric information value is in the alarm area, identification display may be performed. For example, when the biometric information value is included in the caution level range, the background is displayed in red when it is included in the warning level range, or characters are displayed. As a result, the medical staff and the care staff can understand that the biological information currently having a problem is generated, and can also warn about an input error or the like.

  Further, as continuous biological information displayed on the display screen, biological information (value of biological information) detectable from the state detection device 20 may be updated as needed, read and displayed, or read at a certain timing. You may display the biological information.

  Further, when the measurement biometric information is received from the other measurement device 60 (step S414; Yes), the measurement biometric information is stored (step S416). In this case, the currently displayed biological information value is updated and stored in the individual electronic medical record data 120.

  Here, the timing of the measurement biometric information received from the other measurement device 60 is not limited. Although this figure has been described in step S416 as an example, measurement biological information received in advance may be used. In addition, the measurement biometric information stored in the individual electronic medical record data 120 (that is, the electronic medical record data 452) may be arbitrary. For example, if the value measured once is not correct, it may not be stored but the remeasured value may be stored.

  Then, if there is a registration instruction of the electronic medical record (step S418; Yes), the electronic medical record data 452 of the electronic medical record server 40 is registered (step S420).

[4.6.2 Screen Example]
FIG. 19 is a diagram showing a display screen W500 which is an example when this processing is executed. On the display screen W500, each biological information and the value of the biological information are displayed. As in FIG. 16, the alarm threshold is displayed in the area R 502, and when each biological information value is at the caution level and the warning level, the identification display is as in R 504.

  Further, as shown in the region R506, the previous measurement value may be displayed together. And, on the top of the biological information, the date and time when the previously measured value was measured is also displayed. As a result, the medical staff and the care staff can notice the transition of the biological information value.

  Further, with regard to the displayed biological information value, a value updated in real time may be displayed for continuous biological information, or a value at a certain point in time may be displayed. Also, values stored in the electronic medical record data (individual electronic medical record data 120 or electronic medical record data 452) may be displayed.

  Then, by selecting “Registration” from this screen, the currently displayed biometric information value can be registered (stored) in the electronic medical record data. Also, by referring to the history, it is possible to refer to past biometric information values.

[4.7 Reminder processing]
Subsequently, reminder processing will be described. Reminder processing is processing that can be registered as a reminder what the staff or medical staff (nurse, etc.) should do next. For example, FIG. 20 is an example of a display screen W600 displayed when this processing is performed. By registering the work to be displayed as various reminders, it becomes possible to display on the patient status display screen or the alarm display screen.

[4.8 Patient Information Display Processing]
Subsequently, patient information display processing will be described. The patient information display process is a process capable of displaying information on a patient. For example, it is possible to display, input, and set basic information of a patient, medical care information, attention information, pictograms and the like.

  For example, FIG. 21 is an example of a display screen W700 displayed when this process is performed. The display screen W700 reads out and displays basic information (basic information) such as the patient's name, gender, and blood type from the electronic medical record.

[4.9 Alarm setting and history processing]
Subsequently, alarm setting and history processing will be described. The present process is a process that can set each alarm threshold or set the availability of an alarm. It is also possible to confirm an alarm that has occurred in the past as a history.

  FIG. 22 shows an example of the display screen W800 displayed when the alarm setting / history process is performed. The display screen W800 can set an alarm threshold. For example, as the upper alarm threshold, the threshold of the attention level range can be set to R804, and the threshold of the warning level range can be set to R802.

  Also, as the lower alarm threshold, the threshold of the caution level range can be set to R808, and the threshold of the warning level range can be set to R806.

  In addition, it becomes possible to set whether or not to output an alarm when the warning level or the warning level is entered. For example, in the case of R <b> 810, the alarm is not output (not notified).

  In the display screen W850 shown in FIG. 23, when the warning level is entered, the alarm is set to be output by R850. In this setting, for example, sound or light may be set, or an alarm different from the caution level or the warning level may be set.

[5. Effect of configuration of patient status display device]
And it is also one of the characteristics in this embodiment that these screens can be displayed in a place different from the bed 3. This makes it easier for nurses and doctors to refer to patient information, and can display appropriate patient information even if beds are replaced.

  In particular, in the past, the display screen provided in the bed was not easy to use, and the pictogram displayed on the bedside had to be updated each time and was not easy to use.

  Further, it is necessary to separately manage information that can be acquired by the bed (for example, continuous biological information of the present embodiment) and information that can be acquired from the measurement device (for example, measured biological information of the present embodiment). These can all be connected via the patient status display device 10 (connection device 2000), and can be further stored in an electronic medical record.

  FIG. 24 is an example of the case where an error is notified to the connection device 2000. The display terminal 1000 is connected to the connection device 2000 and integrally disposed on the bedside.

  Here, for example, when connection with the state detection device 20 can not be made, “sensor connection” is displayed in the area R900. Note that this area is not displayed if there is no error. Thereby, no matter what screen the display terminal 1000 is, or even if it is in a state where the display terminal 1000 can not be displayed (for example, when a failure or when the display terminal 1000 is not connected), It becomes possible to reliably notify of important errors and the like.

  Further, the error notification may be notified based on the condition of the patient. In this case, a display (a symbol, a code, etc.) that is not understood by the patient, the family, etc. may be displayed. Further, as a notification method, in addition to displaying, for example, sound may be smoothed out, or notification may be made to the mobile terminal device 55.

[6. Service offer by server / other offer]
Although the process in the above-described embodiment has been described as being performed by the patient state display device 10 for convenience of explanation, the process may be executed in the server 30 and the result may be received by the patient state display device 10.

  That is, various programs (for example, the main program 132, the alarm program 134, the patient state display program 136, the electronic medical record registration program 138) are executed by the server 30 as needed. The same process can be realized by transmitting biological information from the patient state display device 10 to the server 30 and accessing the server 30 by, for example, a WEB browser or a dedicated application.

  Although the patient status display device 10 is also divided into the display terminal 1000 and the connection device 2000, it may be provided as a dedicated patient status display device 10 as an integrated type.

  By separating the display terminal 1000 and the connection device 2000, there is an advantage that the display terminal 1000 can use a tablet terminal that satisfies a predetermined condition. Thus, it may be considered to use a commercially available tablet terminal or computer or to use a smartphone.

  The patient status display device 10 is generally provided near the bed, but the same screen can be displayed by the terminal device 50 and the portable terminal device 55. For example, even if a nurse is traveling, patient information can be confirmed by the portable terminal 55, or by using the terminal 50 at the nurse station, it is possible to perform batch management including other patients. Become.

  Further, even during medical treatment or examination, the terminal device 50 can be used to update the biological information as needed, thereby improving the usability of the electronic medical record.

Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology, it goes without saying that integrated circuits according to such technology can also be used.

  Further, according to one aspect of the present embodiment, continuous biological information is received from a state detection device that continuously detects biological information of a patient, and measurement biological information is received from a measurement device that measures biological information of the patient. Then, the condition of the patient can be determined based on the continuous biological information and the measured biological information. As a result, the patient's state is determined from both of the continuously acquired biological information and, for example, the measured biological information measured by the staff or the like, and therefore, the state of the patient is appropriately determined as compared with the case of judging each information. It is possible to determine.
