BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described below with reference to the drawings. The following embodiments are examples to which the patient condition determination device of the present invention is applied, and the content of the invention is not limited to these embodiments.

[1. Entire system]
First, the overall system in this embodiment will be described. FIG. 1 is a diagram for explaining an entire patient condition display system 1 incorporating a patient condition determination device.

First, a patient P is lying on the mattress 5 placed on the bed 3 . A state detection device 20 is provided on the bed.

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

The patient condition display device 10 has the function of a patient condition determination device, and is connected to the condition detection device 20, connected to the measurement device 60, or connected to another server device or the like via a network. It is being done. Further, by holding the authentication card 65 over the patient condition display device 10, authentication processing (login processing) can be realized.

Log-in is performed by an authorized person such as a staff (nurse, doctor, care staff). By logging in, it is possible to check biometric information values and the content of alarms, and register them in the electronic medical record. Also, the authority may be set for each logged-in person to change the range of operations.

For example, a server 30, an electronic medical record server 40, a terminal device 50, and a mobile 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 within a hospital or facility, or may be provided externally via the Internet.

The electronic medical chart server 40 is a server that stores electronic medical chart information about patients. Normally, it is connected to a network within 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 control room, and it is possible to grasp the state of the patient condition display device 10 even from a distance. Further, the portable terminal device 55 can be wirelessly connected to, for example, a LAN, so that nurses, care staff, and the like can easily check information on the patient condition display device 10 .

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

The connection device 2000 is a device for connecting the display terminal 1000 and various devices. In other words, it serves as a hub for various devices. For example, as shown in FIG. 1, by being connected to the state detection device 20, it is possible to continuously acquire the biological information of the patient, receive the biological information from the measuring device 60 (for example, a thermometer), It is also possible to receive biological information from a device worn by a patient (for example, a wristwatch-type wearable measuring device). Further, by connecting the authentication card 65 to, for example, the communication unit 220, authentication processing (for example, patient authentication and staff authentication) can be realized. As an authentication method, NFC is used as an example of short-range wireless communication in this embodiment. good.

A notification unit 260 is also provided, and can notify, for example, when an error occurs. Furthermore, it is also connectable to a server device or the like via a LAN (the LAN may be a wired LAN or a wireless LAN). The notification unit 260 may be configured such that it is normally invisible and is lit (displayed) only when it is to be notified. Further, instead of the display, for example, the notification may be made by sound such as an alarm sound, warning sound, or voice, or by light.

In this embodiment, the display terminal 1000 is placed on the connection device 2000 and used, but 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 in 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]
Next, the functional configuration of this embodiment will be described with reference to 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 condition display device 10. As shown in FIG.

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

The control unit 100 is a functional unit for controlling the display terminal 1000 as a whole. 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 that stores various programs and various data necessary for the operation of the display terminal 1000 . The storage unit 110 is configured by, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

In addition, the storage unit 110 stores biological information 112, individual electronic medical record data 120, and an alarm threshold table 122. As programs, a main program 132, an alarm program 134, and a patient condition display program 136 are stored. , an electronic medical chart registration program 138 are stored.

The biological information 112 stores continuous biological information 114, which is biological information continuously detected by the state detection device 20, and measured biological information 116 received from the measuring device 60 at arbitrary timing. It should be noted that the measured biometric information can be input manually or a continuous biometric information value can be used as necessary.

FIG. 4 shows an example of the data structure of the continuous biometric information 114. As shown in FIG. The continuous biological information 114 of the present embodiment stores values of biological information detected by the state detection device 20 and values of biological information whose state can be detected from other patients.

That is, they are stored based on continuously detectable values. For example, the date and time of measurement (e.g., "2015/05/16 20:00") and the pulse rate (e.g., "126") and body temperature (e.g., "37.2") as values corresponding to the type of biological information ), respiratory rate (eg, “15”), and SpO2 (eg, “99”) are stored. In other words, the continuous biometric information 114 can acquire predetermined measured values at any time. As a method for acquiring the continuous biological information 114 , it may be acquired from the state detection device 20 or may be acquired from a detection device provided on the bed 3 . Also, various sensors may be provided on the patient's body to obtain the information.

Various kinds of acquired biometric information can be collectively managed as continuous biometric information. The values of these biometric information are different depending on the items detected (for example, when only the body motion detection sensor is used, body motion state, sleep state, patient posture (getting out of bed, being in bed, getting up), Pulse rate and respiration rate are detected as continuous biological information).

The measured biological information 116 stores biological information received from an external measuring device such as a thermometer, a sphygmomanometer, or a body fat meter. For example, as shown in FIG. 5, as the measured biological information 116 of the present embodiment, the date and time of reception (for example, "2015/05/16 20:00") and the type of biological information (for example, "body temperature") , and its value (for example, "37.2") are stored. Also, for example, the systolic blood pressure (eg, "159") and the diastolic blood pressure (eg, "98") are stored.

Further, the detected continuous biological information 114 and the measured biological information 116 may be stored for a predetermined period. For example, data for one day or three days is stored as a period of time to be stored. Also, the continuous biological information 114 and the measured biological information 116 may be stored in the server 30 .

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

In this embodiment, the data is stored in the storage unit 110, but the data in the electronic medical record server 40 may be used directly. In this case, the individual electronic medical chart data 120 need not be stored in the storage unit 110 .

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

FIG. 6 shows an example of the alarm threshold table 122. As shown in FIG. As shown in FIG. 6, alarm threshold values of an upper limit value and a lower limit value are stored for each biological information. Also, a plurality of alarm threshold values can be stored depending on the type of alarm. Further, in this embodiment, two levels of caution level and warning level are stored according to the alarm threshold value.

For example, for "pulse", which is one of the biometric information, a threshold value of the pulse rate (threshold in the range of caution level and warning level) is stored as the biometric information value. As the upper threshold, the caution level is stored as "110" and the warning level is stored as "130". Also, as the lower limit threshold, the caution level is stored as "60" and the warning level is stored as "30".

For example, if the pulse rate is 130 or more or 30 or less, it can be determined that it is within the range of the warning level. Also, if the pulse rate is "110 or more and less than 130" or "greater than 30 and less than or equal to 60", it can be determined that it is included in the caution level range. It should be noted that the threshold may be exceeded (for example, the pulse rate within the warning level range is greater than 130 or less than 30).

In this embodiment, two levels, a caution level and a warning level, are explained for convenience of explanation, but it is of course possible to set a larger range.

The patient condition identification information 124 is information for storing patient conditions. Using the patient state identification information, patient state identification display, which will be described later, is performed. In the present embodiment, patient state identification information (interval patient state identification information) determined based on the patient's biological information in the interval from logout to the present, and patient state identification determined based on the current patient's biological information information (current patient condition identification information) is stored.

Here, as the patient state identification information, states of "normal", "caution", and "warning" are stored. Normal is when the patient's biometric value falls within the alarm threshold range (neither caution level nor warning level). "Caution" is when there is a biometric information value within the threshold range of the caution level among the biometric information values of the patient. Similarly, a "warning" is when there is a biometric information value within the threshold range of the warning level among the patient's biometric information values.

In the present embodiment, the interval patient state identification information is determined based on the biometric information values from the previous logout to the present. Other interval patient condition identification information may also be stored.

In the present embodiment, if even one of the biometric information values corresponds, the patient condition identification information changes. The identification information may be updated. Further, the patient condition identification information may be stored for each biometric information or for each predetermined group instead of one. For example, as a predetermined group, continuous biological information and measured biological information may be separated, and patient condition identification information may be determined and stored based on each patient condition.

Also, the programs stored in the storage unit 110 can be read by the control unit 100 to implement various functions. Specifically, the main function reads and executes the alarm program 134 by reading and executing the main program 132, and the alarm function reads and executes the patient condition display program 136 to display the patient condition. The electronic medical record registration functions are implemented by the functions reading and executing the electronic medical record registration program 138 .

The device communication unit 150 is a functional unit for communicating with a device communication unit 250 which will be described later. In the present embodiment, it is assumed that communication is performed by connecting, for example, with a USB. You may Alternatively, a dedicated connection interface may be provided for communication.

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

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

LAN communication unit 180 is an interface unit that can be connected to a LAN. It is composed of a NIC or the like for connecting to Ethernet (registered trademark). Note that the LAN communication unit 180 may be provided in the connection device 2000 . In this case, the data to be sent is once sent to the connection device 2000 via the device communication unit 150 (250), and then sent to the network. In order to connect to the LAN, it may be connected by wire or may be connected wirelessly.

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

The control unit 200 is a functional unit for controlling the connection device 2000 as a whole. The control unit 200 implements 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 that stores various programs and various data necessary for the operation of the connection device 2000 . The storage unit 210 is configured by, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

The communication unit 220 is a functional unit for communicating with other devices and authentication cards. For example, NFC (Near Field Communication) communication can be performed as short-range wireless communication. In the case of NFC communication, the authentication process is executed by holding the authentication card 65 over the user. Also, if the measuring device 60 has an NFC communication function, it is possible to receive biological information via the connection device 2000 by holding the measuring device 60 over it. Note that the measurement device 60 may be, for example, a device such as a smartphone, or a wearable terminal device such as a watch.

Further, the communication unit 220 may of course use any method such as Bluetooth (registered trademark), TransferJet (registered trademark), ZigBee (registered trademark), and RFID. Alternatively, a LAN (wireless LAN, wired LAN) or the like may be used.

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

Device communication unit 250 is a functional unit for communication between display terminal 1000 and connection device 2000 via device communication unit 150 described above. For example, they may be connected using a USB or the like, or may be connected via a LAN. In this embodiment, for the convenience of explanation, the configuration of the functions of each communication unit is described separately, but may be configured as one. That is, when all communications are performed by Bluetooth, the device communication section 250, the communication section 220, and the interface section 230 are configured as one functional section.

Notification unit 260 is a functional unit that operates when connection device 2000 executes notification processing. For example, if it is desired to display an error, that effect is notified. Any method such as sound, light, display, or vibration can be considered as means for notification.

[2.3 Electronic medical record server]
Next, 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 section 400 , a communication section 410 and a storage section 450 .

The control unit 400 is a functional unit for controlling the electronic medical record server 40 as a whole. The control unit 400 implements 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).

A communication unit 410 is an interface unit for connecting to a network. For example, it is composed of a NIC that can be connected to Ethernet. Communication with other devices can be performed via the communication unit 410 .

The storage unit 450 is a functional unit that stores various programs and various data necessary for the operation of the electronic medical record server 40 . The storage unit 450 is composed of, for example, a semiconductor memory, a HDD (Hard Disk Drive), or the like.

The storage unit 450 also stores electronic medical record data 452 . FIG. 8 shows an example of electronic medical record data. Electronic medical record data stores patient information. For example, as indicated by R100 in FIG. (R102), pictograms, and measured biological information (biological information values) (R104) are stored for each patient.

Here, the attention information is information for calling attention to convey the patient's condition to medical staff, caregivers, and other specialists. For example, it stores information regarding alerts (such as no blowing of the nose), and risk assessments such as bedsore assessment and fall risk assessment. These pieces of information may be managed by flags, or may be managed by characters, icons, pictures, and the like.

Pictogram information may also be stored for easier comprehension. Pictograms are based on information about everyday life. By displaying the pictogram, even people who happen to pass by can consider the patient, thereby providing safety and security. In this way, the pictogram information is information that provides the patient's condition to many people, while the attention information is information that conveys the patient's condition information to specialists.

[3. Screen (state) transition diagram]
Next, the flow of the entire system in this embodiment will be explained using the screen transition diagram (state transition diagram) of FIG.

First, when the system is activated, it is determined whether or not the system is in an alarm state, that is, whether or not each biological information value exceeds the alarm threshold value (or is less than the alarm threshold value). Then, an alarm screen (P100) is displayed as necessary. On this alarm screen, you can confirm that a problem has occurred, but the content of the error is not displayed until you log in. As a result, it is possible to prevent display of error contents that should not be displayed to the patient or family.

Although the alarm screen is also displayed when the system is started, such as when the power is turned on, it may be determined whether or not the system is in an alarm state at any time. Then, when an alarm state occurs, a configuration may be adopted in which transition to an alarm screen is performed as interrupt processing.

Subsequently, the patient condition display screen (P102) is displayed as the main condition. On this screen, nameplate information, pictogram information, caution information, error status, etc. are displayed as basic patient information. As a result, necessary information can be displayed for medical personnel such as nurses and doctors, caregivers, and family members providing care.

The patient status display screen (P102) does not display detailed information because the patient, family members at the hospital, and third parties who visit the patient can see the patient. If necessary, the authentication process is executed, and by logging in, the screen switches to the login screen (P104). From the login screen, it is possible to transition to various screens. For example, a patient information display screen (P114) capable of displaying patient information, a biological information display screen (P106) capable of displaying biological information values, a graph display screen (P108) capable of displaying the history of biological information values, It is possible to switch to an electronic medical record registration screen (P110) for registering biometric information values in an electronic medical record.

Furthermore, it is possible to switch to an alarm setting/history screen (P116) for setting the conditions for the alarm state, and a reminder screen (P112) for setting what to do next (for example, instructions for medication, etc.).

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

[4. Explanation of each process]
Next, each process in this embodiment will be described with reference to the drawings.

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

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

It should be noted that whether or not the alarm threshold is exceeded differs depending on the type of biometric information. Alternatively, both may be determined by criteria (that is, determining whether the vital value is within a predetermined range).

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

Here, if 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, if stuffing processing is selected (step S112; Yes), processing is executed according to the selected stuffing processing (step S114). In addition, each process performed here is mentioned later.

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

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

[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 realized by the control unit 100 reading and executing the alarm program 134 stored in the storage unit 110. .

First, it is determined whether or not there is a device connection error (step S202). If there is a device connection error, an output of the device error is displayed (step S202; Yes→step S204).

Subsequently, it is determined whether or not there is biological information that causes an alarm state (step S202; No→step S206 or step S204→step S206). Specifically, each biometric information value is compared with an alarm threshold value to determine whether or not an alarm state exists. Then, if there is a biological information value that causes an alarm state (step S206; Yes), notification processing is executed (step S208).

As an example of notification processing, notification processing is performed from the notification unit 260, or an alarm screen is displayed on the display unit 170. FIG. At this time, detailed information is not displayed until after login (after being authenticated).

Note that the alarm processing has been described as being executed in step S104 of FIG. 10, but it may be executed as interrupt processing by checking at regular time intervals.

In this manner, if there is biological information that causes an alarm state, it is possible to output an alarm by performing notification processing. Also, even if there is a device connection error, it is possible to output the device error as one of the alarms. Note that the device connection error may be output as another method, or may not be output.

Also, the content of the alarm may be reported to the terminal device 50, the portable terminal device 55, or the like. In this case, for example, depending on the caution level or warning level, the report destination may be changed, or the report content may be changed.

For example, for each patient, a table is stored that stores information on how to make a report in association with the patient's condition and type of biological information. At this time, as the report setting, "OFF" for not reporting, "caution" for reporting at the caution level as the reporting level, and "warning" for reporting at the warning level are stored. Further, depending on the type, "ON" and "OFF" may simply be set, such as whether the user is out of bed.

Also, the report destination may be determined in advance corresponding to the report setting. For example, as the first report destination, "mobile terminal device of the nurse in charge" and "PC" at a nurse station, etc. are set, and as the second destination, "mobile terminal device of the nurse in charge", "PC ' and 'personal doctor's portable terminal device' are determined.

In this case, if the notification setting is "ON" or "caution", the notification is sent to the first notification destination. Also, if the notification setting is "warning", the notification is sent to the second destination. In addition, in the present embodiment, the ``medical nurse'' and ``medicine in charge'' are extracted from the electronic chart. It should be noted that it may be set as report destination information separately from the electronic medical record.

In this way, a report with contents corresponding to the report settings may be sent to a preset report destination. In addition to being set for each patient, a common report destination may be set. For example, assume that a rapid response team is set as an emergency destination for all patients. In this case, for example, if the patient's biometric information value exceeds the emergency threshold, or if a plurality of warning level states occur, an emergency report destination may be notified.

In addition, the report setting is set to report at caution level and warning level, but it is set to each level or higher. For example, when the caution level is set, the first notification destination is notified when the biometric information reaches the caution level, and the second notification destination is notified when the warning level is reached. . That is, the caution level includes the warning level. It should be noted that, depending on the setting, only the caution level may be notified.

[4.3 Patient status display processing]
[4.3.1 Flow of processing]
The patient state display processing will be described with reference to FIG. 12 . The patient condition 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 and executing the patient condition display program 136 stored in the storage unit 110. It is a process that

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

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

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

Also, a pictogram display is created based on general caution information for patients and caregivers stored in the individual electronic medical record data 120 .

Subsequently, a warning area is created based on the warning information (step S308), and error information is generated if there is error information (step S310). Here, the alerting information displayed in the alerting area is created based on information for alerting experts such as medical staff and caregivers. Therefore, the area is created in such a state that the content cannot be understood by a person other than the medical staff, such as the patient or family member, just by looking at it. Also, the error information includes information about alarms, but the area is created in such a way that the contents of the alarm cannot be understood by anyone other than the medical staff such as the patient or the family.

Then, a patient condition display screen is generated and displayed in each area created in the above steps (step S312).

[4.3.2 Patient status identification display process]
Subsequently, patient condition identification display processing is executed to display patient condition identification on the patient condition display screen (step S314). Here, the patient condition identification display processing will be described with reference to FIG. 13 .

First, when logout processing is performed (step S352; Yes), the currently stored patient condition information is once cleared (step S354). Continuous biological information and measured biological information are then received (input) (step S356).

When continuous biometric information or measured biometric information is received, the current patient status (current patient status) is determined (step S358). Here, the current patient state is determined to be any one of "warning", "caution", and "normal" based on all received biometric information. Specifically, if any biometric information value is included in the caution level of the alarm threshold, it is "caution", and if any biometric information value is included in the warning level of the alarm threshold, it is "warning". It is determined.

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

Subsequently, if the interval patient condition is other than "warning" and the current patient condition is "warning", the interval patient condition is set to "warning" (step S362; No→step S364; Yes→step S366). That is, when the interval patient condition is "caution" and "normal", if the current patient condition becomes "warning", the interval patient condition becomes "warning".

If the interval patient condition is "normal" and the current patient condition is "caution", the interval patient condition is set to "caution" (step S362; No → step S364; No → step S368; Yes → step S370). That is, when the interval patient state is "normal" and the current patient state becomes "caution", the interval patient state becomes "caution". If the interval patient state is "Caution", and the current patient state is "Normal" or "Caution", the "Caution" state is maintained (step S362; No→step S364; No→step S368; Yes→step S370).

If the current patient condition remains "normal" and the interval patient condition is "normal", the interval patient condition remains "normal" (step S362; No → step S364; No → step S368; No).

In this way, when the patient state changes to a state with a higher degree of importance such as "warning">"caution">"normal", the interval patient state is updated with that state. In addition, once a state of high importance is reached, the state is maintained until the next time it is cleared (for example, until the timing of the next login).

Then, the patient condition identification display is updated based on the patient condition (interval patient condition, current patient condition) (step S372). As a result, the staff can easily confirm the current patient condition and the worst condition from the last 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 condition identification display will be described with reference to FIG. 14 . FIG. 14(a) is an example of identification display of the patient's condition displayed on the screen. M102 has an identification display based on the interval patient state, and M104 has an identification display based on the current patient state. In the present embodiment, the identification mark M104 is displayed larger in consideration of visibility, but the size may be the same, or the shape and position may be different.

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

The operation will be briefly described with reference to FIGS. 14(c) to (e). In the following description, it is assumed that the previous logout time is t1 and the current time is t2.

In FIG. 14(c), the state of the patient was "normal" at time t1, changed to "warning" once thereafter, and then changed to "caution" until t2.

In this case, the identification display M102 as the interval patient state is displayed in the state of "warning" because it is "warning" once after t1. Further, since the current state (t2) is "Caution", the identification display M104 displays "Caution".

FIG. 14(d) shows a state in which the state of the patient was "caution" at time t1, but is now "normal" at time t2. In this case, the identification display M102 as the interval patient state is displayed to identify the state of "caution". Further, the identification display M104 displays the identification display of "normal" because the state is "normal" at time t2.

FIG. 14(e) shows a case where the patient state was in the "normal" state at time t1, but changed to "caution" and "warning" on the way. Even now (t2), the state is "warning". At this time, the identification display M102 indicating the interval patient condition is "warning", and the identification display M104 indicating the current patient condition is also "warning".

In FIG. 14, two identification indications are provided for convenience of explanation, but a plurality of identification indications may be provided correspondingly. For example, identification display based only on continuous biometric information may be performed in addition to the above-described identification display of the patient's condition (whole). Also, a special identification display may be performed in association with predetermined biological information (for example, respiration rate, etc.).

[4.3.3 Screen example]
Next, a description will be given using a screen example when this processing is executed. FIG. 15 is an example of a patient condition display screen W200. On the display screen W200, the name of the patient, the name of the attending physician, etc. are displayed in areas R202 and R204 as nameplate information. These items are appropriately selected from the patient information registered in the electronic medical chart and displayed.

A pictogram or the like is displayed as a pictogram area in the area R206. Further, in the region R208, particularly attention calling information is displayed among the attention information. The alert information is a display that only specialists such as medical workers and staff members of nursing homes can understand.

Also, the R210 is notified that an error has occurred. Here, in order to display the error content, it is necessary to execute authentication processing and switch to another screen. As a result, it is possible to prevent non-experts such as medical staff and caregivers from confirming errors.

Further, the operation/state of the state detection device 20 may be displayed on the display screen W200. For example, the state may be displayed as shown in region R212. It also displays the connection status of the sensor. As a result, it is possible to grasp at a glance whether the sensor is unconnected or unavailable.

In addition, a patient condition identification display is provided. In FIG. 15, an identification display of the interval patient state is displayed in M200, and an identification display of the current patient state is displayed in M202. Various methods can be used to identify the patient's condition. For example, an underline may be displayed under the patient's name, and identification may be performed by color or thickness of the line, or an icon may be displayed separately. .

Further, in the present embodiment, the identification display of the patient's condition is performed for the entire biological information including the continuous biological information and the measured biological information, but for example, the continuous biological information and the measured biological information may be displayed separately. Alternatively, the biological information may be displayed separately for each biological information, such as displaying only respiration separately.

[4.4 Biological information display processing]
Next, biometric information display processing will be described. The biometric information display process is a process corresponding to P106 in FIG. That is, it is a process of displaying the biometric information value based on the patient's electronic medical record data.

FIG. 16 shows a display screen W300 as an example of the screen when this process is executed. The display screen W300 displays a biometric information value for each biometric information. Further, the date and time when the displayed biometric information value was registered is displayed in the region R302.

Furthermore, next to the biometric information value, an alarm threshold value is displayed in an area R304 so that it is easy to understand. That is, the alarm thresholds are displayed so that the caution level range and the warning level range are clearly defined.

Further, the background may be changed when the displayed biometric information value is within the caution level or warning level range. For example, R306 displays "126 bpm" as the pulse rate. Since this biometric information value is included in the caution level, the background is identifiably displayed in the caution level color (for example, yellow).

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

Further, R310 is a display for calling attention to medical personnel, care staff, and the like. For example, it is possible to identify biometric information that has been problematic between the previous log-out and the current log-in. As a result, for example, if the current patient condition identification information is "caution", the staff can log in to confirm that there was a problem with breathing.

[4.5 Graph display processing]
Next, the graph display processing will be explained. The graph display process is a process executed at P108 in FIG. In other words, it is a process of displaying the transition of the biometric information registered in the electronic medical record in a graph.

FIG. 17 shows a display screen W400 as an example of the screen when this process is executed. The display screen W400 displays the transition of each biometric information value. Then, the area of the alarm threshold is also displayed in the graph of each biological information. As a result, it is possible to easily confirm when there is an abnormality in the biological information.

It should be noted that if one piece of biometric information is selected while this graph is being displayed, a graph showing only that biometric information may be displayed.

[4.6 Electronic medical record registration process]
[4.6.1 Flow of processing]
Next, electronic medical chart registration processing for registering biometric information in an electronic medical chart will be described with reference to FIG. 16 . The electronic medical record registration process is realized by the control unit 100 reading and executing the electronic medical record registration program 138 stored in the storage unit 110 .

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

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

At this time, if the biometric information value is within the alarm area, an identification display may be performed. For example, if the biometric information value is within the caution level range, the background is displayed in yellow, and if it is within the warning level range, the background or text is displayed in red. As a result, the medical staff and care staff can recognize that the biometric information is currently causing problems, and it is possible to call attention to input errors and the like.

As the continuous biometric information displayed on the display screen, the biometric information (value of biometric information) that can be detected from the state detection device 20 may be updated and displayed at any time, or may be read out at a certain timing. You may display the living body information.

When the measured biological information is received from another measuring device 60 (step S414; Yes), the measured biological 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 measured biological information received from the other measuring device 60 is not limited. In this figure, step S416 is described as an example, but the measured biological information received in advance may be used. Also, the measured biological information stored in the individual electronic medical chart data 120 (that is, the electronic medical chart data 452) may be arbitrary. For example, if a value measured once is not correct, it may not be stored, and a remeasured value may be stored.

Then, when there is an instruction to register an electronic medical chart (step S418; Yes), the electronic medical chart data 452 of the electronic medical chart server 40 is registered (step S420).

[4.6.2 Screen example]
FIG. 19 is a diagram showing a display screen W500 as an example when this process is executed. The display screen W500 displays each biometric information and the value of the biometric information. As in FIG. 16, the alarm threshold is displayed in the area R502, and when each biometric information value is at the caution level or the warning level, the identification display is R504.

Also, as shown in area R506, the previous measurement value may be displayed together. The date and time when the last measured value was measured is also displayed above the biological information. As a result, medical staff, nursing staff, and the like can notice transitions in biometric information values.

As for the displayed biometric information values, values updated in real time may be displayed for continuous biometric information, or values at a certain point in time may be displayed. Also, the values stored in the electronic medical chart data (individual electronic medical chart data 120 or electronic medical chart data 452) may be displayed.

By selecting "registration" from this screen, the currently displayed biometric information value can be registered (stored) in the electronic medical record data. Further, by referring to the history, past biometric information values can be referred to.

[4.7 Reminder processing]
Next, the reminder processing will be explained. Reminder processing is processing that allows staff and medical personnel (nurses, etc.) to register reminders of what to do next. For example, FIG. 20 is an example of a display screen W600 displayed when this process is executed. By registering tasks to be displayed as various reminders, it is possible to display them on the patient status display screen and the alarm display screen.

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

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

[4.9 Alarm setting and history processing]
Next, alarm setting/history processing will be described. This process is a process capable of setting each alarm threshold value and setting whether or not an alarm is to be issued. It is also possible to check past alarms as a history.

FIG. 22 shows an example of a display screen W800 displayed when alarm setting/history processing is executed. The display screen W800 allows each alarm threshold to be set. For example, as the upper limit alarm threshold, the caution level range threshold can be set at R804, and the warning level range threshold can be set at R802.

Also, as the lower limit alarm threshold, the threshold for the caution level range can be set at R808, and the threshold for the warning level range can be set at R806.

It is also possible to set whether to output an alarm when the caution level or warning level is entered. For example, in the case indicated by R810, it is set not to be output (not notified) as an alarm.

In the display screen W850 of FIG. 23, R850 is set to output an alarm when the caution level is entered. It should be noted that, for this setting, for example, sound and light may be set, and it is also possible to set separate alarms for caution level and warning level.

[5. Effect of Configuration of Patient Status Display Device]
One of the features of this embodiment is that these screens can be displayed in a place other than the bed 3 . This makes it easier for nurses and doctors to refer to patient information, and allows appropriate patient information to be displayed even if the beds are switched.

In particular, in the past, the display screen provided on the bed was inconvenient, and the pictograms displayed on the bedside had to be updated each time.

In addition, information that can be acquired in bed (eg, continuous biological information in this embodiment) and information that can be acquired from a measuring device (eg, measured biological information in this embodiment) need to be managed separately. These can all be connected via the patient condition display device 10 (connecting device 2000), and can be stored in an electronic medical record.

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

Here, for example, when the connection with the state detection device 20 cannot be established, "sensor connection" is displayed in the region R900. Note that nothing is displayed in this area when there is no error. As a result, regardless of what kind of screen the display terminal 1000 has, or even if the display terminal 1000 is in a state where display is not possible (for example, when the display terminal 1000 is out of order, or when the display terminal 1000 is not connected, etc.), It is possible to reliably notify an important error or the like.

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

[6. Service provision/other provision by server]
For convenience of explanation, the processing in the above-described embodiment is performed by the patient condition display device 10, but the server 30 may execute the processing and the patient condition display device 10 may receive the results.

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

Further, the patient condition display device 10 is also composed of the display terminal 1000 and the connection device 2000 separately, but the patient condition display device 10 may be provided as a dedicated patient condition display device 10 as an integral 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. As a result, it is possible to use commercially available tablet terminals, computers, and smartphones.

Moreover, although the patient condition display device 10 is generally provided near the bed, the same screen can be displayed on the terminal device 50 and the mobile terminal device 55 . For example, even if a nurse is patrolling, patient information can be checked on the portable terminal device 55, and by using the terminal device 50 at the nurse station, it is possible to collectively manage patients including other patients. Become.

In addition, the terminal device 50 can be used to update the biological information at any time even during medical treatment or examination, thereby improving usability of the electronic medical record.
