Description

[Technical field]

[0001] The present invention relates to a biological information display device, a biological information display system, and a program. [Background technology]

[0002] Conventionally, there is known a system for monitoring the condition of a patient lying in a bed in a medical institution such as a hospital. For example, there is known a vital sign monitoring system that includes a bedside monitor that is provided at the bedside of the patient and acquires and displays vital sign of the patient by a medical telemeter, and a central monitor that is provided at a nurse's station and acquires the vital sign of the patient from the bedside monitor and displays the vital sign of the patient in the same display format as that of the bedside monitor (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-174 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the vital sign monitoring system described in Patent Document 1 could only display the vital sign of the patient in the bed where the bedside monitor was installed. For example, if a nurse is not at the nurse's station and is visiting each bed in the hospital room, the nurse cannot check the vital sign on the central monitor. Even if the nurse is given a mobile terminal to display the vital sign of the patient on the mobile terminal, the nurse will spend most of the time in the hospital room with both hands full, and in this state, the nurse can only move his / her eyes, ears, and mouth, so there is a risk that the nurse will not be able to take the mobile terminal out of his / her pocket and visually check the vital sign of other patients than the patient in the bed he / she is currently in.

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the illustrated examples.

[0029] First, the device configuration of this embodiment will be described with reference to Figs. 1 to 4. Fig. 1 is a block diagram showing the configuration of a monitoring system 100 of this embodiment. Fig. 2 is a block diagram showing the functional configuration of a pulse oximeter 1. Fig. 3 is a block diagram showing the functional configuration of a patient information communication device 2. Fig. 4 is a block diagram showing the functional configuration of a server 3.

[0030] 1, a monitoring system 100 as a biological information display system of this embodiment is installed in a medical facility such as a hospital, and monitors the condition of patients who are admitted to the medical facility and are in their hospital rooms. The monitoring system 100 includes a plurality of pulse oximeters 1 as measuring devices, a plurality of patient information communication devices 2 as biological information display devices, and one server 3 as a management device.

[0031] The pulse oximeter 1 is connected to a patient information communication device 2 so as to be able to communicate by wire. The wired communication method between the pulse oximeter 1 and the patient information communication device 2 is, for example, USB (Universal Serial Bus). The patient information communication device 2 is connected to a server 3 so as to be able to communicate by wireless. The wireless communication method between the patient information communication device 2 and the server 3 is, for example, sub-gigahertz wireless (wireless using a frequency band below 1 GHz). This allows data measuring the vital values ​​of the biological information acquired by the pulse oximeter 1 (i.e., measurement data) to be transferred in real time to the server 3 via the patient information communication device 2.

[0032] In this embodiment, real-time transfer of measurement data refers to continuous monitoring of the patient's condition based on the measurement data, i.e., monitoring, and does not include delays caused by processing and transfer of data, etc.

[0033] The pulse oximeter 1 is a device that is attached to a living body part such as a finger of a patient (subject) and measures vital values ​​such as percutaneous arterial oxygen saturation (SpO2) and pulse rate. The main body of the pulse oximeter 1 in this embodiment is attached to the patient's wrist like a wristwatch, for example.

[0034] As shown in FIG. 2, pulse oximeter 1 includes a control unit 11, an operation unit 12, a memory unit 13, a detection unit 14, a measurement control unit 14a, an LED (Light Emitting Diode) drive circuit 14b, an analog front-end circuit 14c, an AD (Analog to Digital) converter 14d, a display unit 15, a wireless communication unit 16, a wired IF (InterFace) circuit 17, a power supply unit 18, a charging control unit 18a, a timer unit 19, and the like.

[0035] The control unit 11 is composed of a CPU (Central Processing Unit), a RAM (Random Access Memory), etc. The CPU of the control unit 11 reads out programs such as system programs and application programs stored in the storage unit 13, expands them in the RAM, and executes various processes in cooperation with the expanded programs.

[0036] The operation unit 12 includes various switches, various function buttons, etc., and outputs operation signals from these to the control unit 11.

[0037] The storage unit 13 is made up of a semiconductor non-volatile memory such as a flash memory, and stores various programs and various data. The storage unit 13 can also store measurement data during a first measurement mode, which will be described later.

[0038] The detection unit 14 is also called a probe, and is configured to be attachable to a biological part such as a patient's fingertip. The detection unit 14 controls the LED drive circuit 14b by the measurement control unit 14a, emits red light and infrared light toward the biological part by an LED light emitting unit (not shown) provided in the detection unit 14, and receives an analog signal of the transmitted light (or reflected light) from the biological part by a light receiving unit such as a photodiode provided in the detection unit 14, and performs noise removal and signal amplification by the analog front-end circuit 14c to prepare a voltage signal to be input to the AD converter 14d, and then converts it into digital measurement data by the AD converter 14d.

[0039] The display unit 15 is configured with an LCD (Liquid Crystal Display), an EL (Electro-Luminescence) display, or the like, and performs display according to the instruction of a display signal input from the control unit 11. Information displayed on the display unit 15 includes, in addition to the SpO2 value and pulse rate, for example, the type of measurement mode, remaining battery power, date and time information, and the like, which will be described later.

[0040] The wireless communication unit 16 has a wireless interface such as a wireless antenna and a wireless module for transmitting and receiving data to and from the server 3, etc., via wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). Note that the wireless communication unit 16 is not used for real-time transfer of measurement data, but is used when an abnormality occurs in the pulse oximeter 1 and the pulse oximeter 1 is not connected by wire.

[0041] The wired IF circuit 17 is a circuit section that enables wired communication including real-time transfer of measurement data with the server 3, and is connected to one end of a connection line 17a of, for example, a USB cable. The connection line 17a connects the wired IF circuit 17 in the pulse oximeter 1 and the IF circuit 25 in the patient information communication device 2, and functions as a communication line that enables data transmission and reception and a power line that enables power supply to the pulse oximeter 1. Therefore, the wired IF circuit 17 is also configured to be able to receive power.

[0042] The power supply unit 18 supplies each part of the pulse oximeter 1 with the power required for the operation of that part. The power supply unit 18 supplies power output from a battery (not shown) at the operating voltage of each part. As the battery, a secondary battery such as a rechargeable battery or a rechargeable built-in battery is used, but a dry cell may also be used as a primary battery. The charging control unit 18a controls the charging of the power supply unit 18 under the control of the control unit 11.

[0043] The timekeeping unit 19 is a real-time clock that keeps track of the current date and time, and outputs the current date and time information to the control unit 11.

[0044] The pulse oximeter 1 configured as described above can operate in a first measurement mode in which it performs measurement independently without any external connection, driven by the battery of the power supply unit 18, and in a second measurement mode in which it performs measurement while transferring measurement data in real time to the server 3 via the patient information communication device 2. Whether the current measurement mode of the pulse oximeter 1 is the first measurement mode or the second measurement mode is displayed on the display unit 15, for example.

[0045] The second measurement mode is a mode that operates when real-time transfer of measurement data is possible, and operates in a situation where, for example, the patient is in his / her bed in the hospital room (laying down) and the connection line 17a is connected to the wired IF circuit 17. Also, during the second measurement mode, unless there is any particular abnormality, the device operates to perform measurement while receiving power via the connection line 17a and the wired IF circuit 17 in a wired connection. This allows continuous measurement and real-time transfer of measurement data without worrying about the remaining battery level of the power supply unit 18. On the other hand, if the power supply is interrupted due to some abnormality during operation in a wired connection even though communication is possible, the pulse oximeter 1 operates to perform measurement while automatically receiving power from the power supply unit 18.

[0046] The case where real-time transfer of measurement data is not possible refers to a case where the pulse oximeter 1 is not connected to the patient information communication device 2 via a wired connection, or a case where data transmission / reception between the pulse oximeter 1 and the patient information communication device 2 is not performed normally due to some abnormality even if the pulse oximeter 1 is connected via a wired connection. In this case, the pulse oximeter 1 operates in the first measurement mode. More specifically, the first measurement mode is a mode in which the pulse oximeter 1 operates when real-time transfer of measurement data is not possible, and operates in a situation where, for example, the patient leaves his / her bed (gets out of bed) and the connection line 17a is disconnected from the wired IF circuit 17.

[0047] When the patient gets out of bed, it is necessary to disconnect the connection line 17a, but by disconnecting the connection line 17a from the pulse oximeter 1 without stopping the first measurement mode, the operation automatically switches to storing the data in the built-in memory, the storage unit 13, and measurement can be continued while the patient is out of bed. After that, when the connection line 17a is reconnected when the patient returns to the bed, the measurement data recorded in the storage unit 13 while the patient was out of bed is automatically transferred to the server 3.

[0048] When disconnecting the connection line 17a when getting out of bed, in order to distinguish between unintentional disconnection of the connection line 17a and this, a bed exit button (operation unit 22 described later) is provided on the patient information communication device 2 provided at the bedside of each patient, which performs one operation (such as unlocking the wired connection or pressing the bed exit button) to recognize that the connection line 17a is to be disconnected when getting out of bed. When intentionally disconnecting the connection line 17a, the connection line 17a is disconnected and the wired connection is cut off after pressing this bed exit button, and the server 3 determines that the wired connection has been cut off and that there is no abnormality.

[0049] The bed exit button is pressed not only when the connection line 17a connecting the pulse oximeter 1 and the patient information communication device 2 is disconnected, but also when the connection lines for various sensors connected to the patient information communication device 2 are disconnected.

[0050] Furthermore, the pulse oximeter 1 may be configured such that various setting information for the pulse oximeter 1 can be set by commands from external devices (such as the patient information communication device 2, the server 3, or an MT (Mobile Terminal) (not shown)). The MT is a mobile terminal such as a tablet PC (Personal Computer) or a smartphone that is carried by each user such as a doctor or a nurse. The various setting information includes setting parameters such as the measurement cycle of each sensor including the detection unit 14, operation settings such as intermittent measurement, thresholds for determining abnormalities other than the measurement data being transferred in real time, time setting information for the timer unit 19, setting information for whether or not to enable auto power off and the time, setting information for the device number of the pulse oximeter 1, etc.

[0051] 1 and 3, the patient information communication device 2 is a terminal device that is installed at the bedside of each of multiple patients in a hospital room at a medical institution. The patient information communication device 2 transfers measurement data measured by a pulse oximeter 1 to a server 3 in real time. Such a patient information communication device 2 is installed at the bedside of each patient and is also called a bedside terminal.

[0052] In addition to the pulse oximeter 1, various sensors that monitor the patient's vital signs (e.g., a breathing sensor 4, a body movement sensor 5, a bed exit sensor 6, a pulse sensor, a body temperature sensor, a blood pressure monitor, etc.) can also be connected to the patient information communication device 2.

[0053] As shown in Figure 3, the patient information communication device 2 includes a control unit 21 as a control means, an operation unit 22, a memory unit 23, a display unit 24 as a display means, an IF circuit 25, a wireless communication unit 26 as a communication means, a power supply unit 27, an NFC (Near Field Communication) reader 28, and an output unit 29 as an alarm means.

[0054] The control unit 21 is composed of a CPU, a RAM, etc. The CPU of the control unit 21 reads out various programs such as system programs and application programs stored in the storage unit 23, expands them in the RAM, and executes various processes in cooperation with the expanded programs.

[0055] The operation unit 22 includes various switches, various function buttons, etc., and outputs operation signals from these to the control unit 21. The various function buttons include the above-mentioned bed exit button that is pressed when disconnecting the connection line 17a from the pulse oximeter 1, when disconnecting the connection line 17a of the pulse oximeter 1, and when disconnecting the connection lines for the various sensors 4, 5, and 6.

[0056] The storage unit 23 is composed of a semiconductor non-volatile memory such as a flash memory, and stores various programs and various data. The storage unit 23 also stores in advance a patient ID that is used when linking a patient with each measurement data in the server 3. The storage unit 23 also stores a patient information communication processing program for executing a patient information communication process described later.

[0057] The display unit 24 is composed of, for example, an LCD, an EL display, etc., and performs display according to the instruction of a display signal input from the control unit 21. Information displayed on the display unit 24 includes a display screen having measured values ​​and measured waveforms of the measurement data measured by the pulse oximeter 1 connected to the patient information communication device 2 and the various sensors 4, 5, and 6 described above.

[0058] IF circuit 25 is a circuit section that enables wired communication, including real-time transfer of measurement data between pulse oximeter 1 and various sensors 4, 5, and 6, and wired communication with wireless communication section 26 and NFC reader 28, and includes a connection section for connection line 17a. In addition, since power is supplied from patient information communication device 2 to pulse oximeter 1 and various sensors 4, 5, and 6, IF circuit 25 is also configured to be able to supply this power.

[0059] The wireless communication unit 26 has a wireless interface including a wireless antenna and a wireless module for transmitting and receiving data to and from the server 3 by sub-gigabit wireless communication, for example. That is, in this embodiment, the patient information communication device 2 and the server 3 transmit and receive data by wireless communication. However, this is not limited to this, and the patient information communication device 2 and the server 3 may communicate with each other by wire.

[0060] The power supply unit 27 is a power supply unit that obtains power from a system power supply or the hospital's private power generating device and sends the power to each part of the patient information communication device 2 including the IF circuit 25, and can also supply power to the pulse oximeter 1 via the connection line 17a.

[0061] NFC reader 28 is a reading unit that reads information stored in a communication target by using the NFC wireless communication method, and outputs the read information to control unit 21 via IF circuit 25. NFC reader 28 reads the user ID of a user, such as a nurse, that is stored in an ID card carried by the user.

[0062] The output unit 29 includes an audio output unit that outputs various sounds and a vibration output unit that outputs vibrations, and outputs alarm sounds, vibrations, etc., in response to the control of the control unit 21 when an alarm is sounded for the patient corresponding to the device itself or another patient corresponding to the patient information communication device 2 installed on another bed.

[0063] In this embodiment, for example, the control unit 21, operation unit 22, storage unit 23, display unit 24, and output unit 29 of the patient information communication device 2 are realized by a tablet PC 20. The tablet PC 20 may be configured to have a wireless communication unit capable of wireless communication such as Bluetooth or Wi-Fi.

[0064] As shown in Figures 1 and 4, the server 3 receives measurement data of multiple patients from multiple pulse oximeters 1 worn by multiple patients via multiple patient information communication devices 2, stores and manages the measurement data for the multiple patients, and functions as a centralized management station (centralized management system, SS (Station Server)) that simultaneously displays the multiple measurement data in real time.

[0065] 4, the server 3 includes a control unit 31, an operation unit 32, a storage unit 33, a display unit , a wireless communication unit 35, etc. The various units of the server 3 are connected to each other via a bus .

[0066] The control unit 31 is composed of a CPU, a RAM, etc. The CPU of the control unit 31 reads out various programs such as system programs and application programs stored in the storage unit 33, expands them in the RAM, and executes various processes in cooperation with the expanded programs.

[0067] The operation unit 32 has a keyboard, a mouse, and other pointing devices, receives key inputs and position inputs from the user, and outputs these operation signals to the control unit 31.

[0068] The storage unit 33 is configured with a large-capacity recording medium such as a hard disk drive (HDD) or a solid state drive (SSD), and stores various programs and various data. The storage unit 33 also stores a server processing program for executing server processing, which will be described later.

[0069] The display unit 34 is composed of, for example, an LCD, an EL display, etc., and performs display according to the instructions of a display signal input from the control unit 31. Information displayed on the display unit 34 includes a display screen having measured values ​​and measurement waveforms of all patients' vital values ​​measured by all pulse oximeters 1 and the above-mentioned various sensors 4, 5, 6 connected to all patient information communication devices 2 of the monitoring system 100.

[0070] The wireless communication unit 35 includes, for example, a wireless communication unit using sub-gigabit wireless communication for communicating with the patient information communication device 2, and a wireless communication unit such as Bluetooth or Wi-Fi for wirelessly communicating with the pulse oximeter 1, MT (not shown), etc.

[0071] Of the components constituting the server 3, at least the display unit 34 is installed in a so-called nurse station in a medical facility where nurses are stationed, for example, so that the nurses can visually check the patient's measurement data at any time.

[0072] Next, the operation of the monitoring system 100 will be described with reference to Fig. 5 to Fig. 7. Fig. 5 is a flowchart showing patient information communication processing. Fig. 6 is a flowchart showing server processing. Fig. 7 is a diagram showing a measurement data display screen 200.

[0073] First, referring to Fig. 5, the patient information communication process executed by each patient information communication device 2 in a medical facility will be described. The pulse oximeter 1 can be connected / disconnected via a wired IF circuit 17 (connection line 17a) to the patient information communication device 2 provided at the side of the bed. When a patient is seated on the corresponding bed, the pulse oximeter 1 is capable of measuring vital values ​​such as SpO2 and pulse rate.

[0074] The patient information communication device 2 has patient-related information of a patient who will be placed in a bed in which the patient information communication device 2 is installed set in advance by input from a user via the operation unit 22, by receiving patient-related information from the server 3, etc., and stores this information in the storage unit 23, and also stores terminal information for identifying the device itself in the storage unit 23. The patient-related information is information such as the patient's identification information, the identification information of the bed in which the patient will be placed, the patient's name, and sex.

[0075] It is also assumed that a threshold value for determining whether the measurement data is abnormal or not is stored in advance in the storage unit 23. The threshold value for the measurement data has, for example, an upper limit value and a lower limit value. For example, it is assumed that the measurement data is determined to be abnormal when the SpO2 of the measurement data exceeds the upper limit value of the threshold, and is determined to be abnormal when the SpO2 of the measurement data is below the lower limit value of the threshold.

[0076] In the patient information communication device 2, for example, when the power is turned on, the control unit 21 executes the patient information communication process in accordance with the patient information communication processing program stored in the storage unit 23.

[0077] 5, the control unit 21 determines whether the pulse oximeter 1 is wired connected to its own patient information communication device 2 via the IF circuit 25 and whether measurement data of a vital value measured from the connected pulse oximeter 1 has been received (step S11). The measurement data received in step S11 is measurement data of the second measurement mode. The measurement data includes a vital value and measurement date and time information based on current date and time information at the time when the vital value was measured by the timer unit 19.

[0078] Also, for example, when the pulse oximeter 1 is connected to the patient information communication device 2 by wire and a user such as a nurse inputs an instruction to transfer measurement data via the operation unit 12 or the operation unit 22, the measurement data in the first measurement mode read from the memory unit 13 is transferred from the pulse oximeter 1 to the patient information communication device 2 and displayed on the display unit 24. Also, the measurement data is transferred from the patient information communication device 2 to the server 3, displayed on the display unit 34, and stored in the memory unit 33. For this reason, in this embodiment, the measurement data in the second measurement mode will be described.

[0079] When the control unit 21 receives the measurement data (step S11; YES), the control unit 21 reads out the threshold value of the measurement data from the storage unit 23, and uses the read out threshold value to determine whether the measurement data received in step S11 is abnormal (step S12). In step S12, the SpO2 and pulse rate of the measurement data are determined to be abnormal. When the measurement data is abnormal (step S12; YES), the control unit 21 generates alarm information for the measurement data indicating that at least one of the SpO2 and pulse rate of the measurement data is abnormal, and transmits the generated alarm information for the measurement data to the server 3 via the wireless communication unit 26 together with the terminal information of the patient information communication device 2 of the control unit 21 stored in the storage unit 23 (step S13).

[0080] Then, the control unit 21 transfers the measurement data received in step S11 to the server 3 via the wireless communication unit 26 (step S14). Then, the control unit 21 displays the alarm information of the measurement data generated in step S13 on the display unit 24 together with the patient-related information stored in the memory unit 23 and the measurement data received in step S11, and notifies the patient of the alarm by outputting a sound and a vibration via the output unit 29 (step S15). The measurement data is displayed as measured values ​​of vital values ​​and a measurement waveform, and the same is true for other measurement data displays in the patient information communication device 2 or the server 3.

[0081] If the measurement data is not abnormal (step S12; NO), the control unit 21 transfers the measurement data received in step S11 to the server 3 via the wireless communication unit 26 together with the terminal information of the patient information communication device 2 stored in the memory unit 23 (step S16). Then, the control unit 21 displays the measurement data received in step S11 on the display unit 24 together with the patient-related information stored in the memory unit 23 (step S17).

[0082] If no measurement data has been received (step S11; NO), or after execution of step S15 or S17, control unit 21 determines via IF circuit 25 whether pulse oximeter 1 is wired connected to its own patient information communication device 2 and whether device abnormality information indicating an abnormality in the pulse oximeter 1 has been received from the connected pulse oximeter 1 (step S18). If device abnormality information has been received (step S18; YES), control unit 21 generates alarm information of the device abnormality in the connected pulse oximeter 1, and transmits the generated alarm information of the device abnormality to server 3 via wireless communication unit 26 together with terminal information of its own patient information communication device 2 stored in storage unit 23 (step S19).

[0083] Then, the control unit 21 transmits the device abnormality alarm information generated in step S19 to the server 3 together with the patient-related information stored in the storage unit 23 (step S19). The information is displayed on the display unit 24, and an alarm of the device abnormality of the connected pulse oximeter 1 is notified by sound output and vibration output via the output unit 29 (step S20).

[0084] If the device abnormality information has not been received (step S18; NO), or after executing step S20, the control unit 21 determines whether or not the control unit 21 has received, from the server 3 via the wireless communication unit 26, measurement data of another patient implanted in a patient information communication device 2 other than the control unit 21, or alarm information of a device abnormality, together with the patient-related information of the other patient (step S21). If the control unit 21 has not received the alarm information and patient-related information of the other patient (step S21; NO), the process proceeds to step S11.

[0085] When alarm information and patient-related information of another patient are received (step S21; YES), the control unit 21 deletes personal information from the patient-related information of the other patient received in step S21 (step S22). Personal information is information about an individual other patient, and is information that can identify the patient by descriptions contained in the information. Here, personal information is information that can identify a patient by people other than the user, such as a doctor or nurse (the patient corresponding to the patient information communication device 2 of the user, other patients, etc.), and is, for example, the name and gender of the other patient.

[0086] Then, the control unit 21 displays the alarm information received in step S21 on the display unit 24 together with the patient-related information from which the personal information was deleted in step S22, notifies the other patient of the alarm by outputting sound and vibration via the output unit 29 (step S23), and proceeds to step S11. Since the patient-related information from which the personal information was deleted is displayed on the display unit 24, it is possible to prevent the personal information of the other patient for whom the alarm has occurred from being known to the patient corresponding to the patient information communication device 2 of the own machine.

[0087] Note that in the nurse mode, when a command to display the personal information of the patient corresponding to the displayed alarm information is input by the user via the operation unit 22, the control unit 21 may be configured to display the personal information deleted in step S22 on the display unit 24. The nurse mode is a mode in which a nurse as a user is using the patient information communication device 2, and for example, the control unit 21 reads an ID card held by the nurse via the NFC reader 28, and sets the patient information communication device 2 to the nurse mode when it authenticates that the read nurse ID is valid. In the nurse mode, patients and other persons other than the authenticated nurse cannot use the patient information communication device 2.

[0088] Furthermore, in steps S15, S20, and S23, the alarm information may be not only displayed, but also outputted in sound and vibration, and the output expression may be changed depending on the patient to whom the alarm is directed (for example, the patient corresponding to the patient information communication device 2 itself and other patients) and the type of alarm information (alarm information of measurement data, alarm information of equipment abnormality). The expression of the sound output may be, for example, the scale, volume, length, melody, etc. of the sound. The expression of the vibration output may be, for example, the volume, length, pattern, etc. of the vibration.

[0089] Furthermore, with regard to the period of alarm information notification in steps S15, S20, and S23, when a user who starts treating a patient corresponding to the alarm information inputs an instruction to cancel the notification of the alarm information via the operation unit 22 in any of the patient information communication devices 2 in the monitoring system 100 (after transition to the nurse mode), the notification of the alarm information corresponding to the instruction to cancel may be stopped in all of the patient information communication devices 2. This stopping of notification allows a user who is not treating the alarm information to recognize that another user has started treatment.

[0090] The notification of the alarm information of other patients may be stopped after a preset period of time, and may be configured to resume (repeated notification) after a further predetermined time.

[0091] Furthermore, in all patient information communication devices 2, after an operation input to start treatment is made, until an operation input to end treatment is made via the operation unit 22, alarm information, identification information of the user undergoing treatment, patient-related information (excluding personal information) of the patient undergoing treatment, and display information indicating "treatment in progress" may be displayed on the display unit 24. Furthermore, when sub-gigabit wireless (wireless using a frequency band less than 1 GHz) is used between the patient information communication device 2 and the server 3, there is a limit to the amount of data that can be transferred, so the measurement data of other patients received from the server 3 may not include waveform information. Alternatively, the measurement data may be configured to include waveform information only when there is sufficient data to be transferred.

[0092] Next, referring to Fig. 6, a server process executed by the server 3 in parallel with the patient information communication process of Fig. 5 will be described. It is assumed that the server 3 stores in advance in the storage unit 33 the patient-related information of each patient and the terminal information of each patient information communication device 2 in association with each other, for example, through input from a user via the operation unit 32.

[0093] In the server 3, for example, when the power is turned on, the control unit 31 executes server processing according to a server processing program stored in the storage unit 33.

[0094] 6, first, corresponding to step S13, S14, or S16 of the patient information communication process in FIG. 5, the control unit 31 determines whether or not the terminal information and the measurement data have been received from the patient information communication device 2 via the wireless communication unit 35 (step S31). If the terminal information and the measurement data have been received (step S31; YES), the control unit 31 stores the measurement data received in step S31 in the storage unit 33 in association with the patient-related information stored in the storage unit 33 in association with the terminal information received in step S31 (step S32).

[0095] Then, the control unit 31 displays the measurement data stored in step S32 on the display unit 34 in association with the patient-related information stored in step S32 (step S33). Since the display unit 34 is visible only to the user and not to the patient, in step S33 and step S36 described below, the displayed patient-related information may include personal information.

[0096] If the terminal information and the measurement data have not been received (step S31; NO), or after execution of step S33, the control unit 31 determines whether or not the terminal information and the alarm information have been received from the patient information communication device 2 via the wireless communication unit 35 (step S34), corresponding to step S13 or S19 in Fig. 5. If the terminal information and the alarm information have not been received (step S34; NO), the process proceeds to step S31.

[0097] When the terminal information and the alarm information are received (step S34; YES), the control unit 31 stores the alarm information received in step S34 in the storage unit 33 in association with the patient-related information stored in the storage unit 33 in response to the terminal information received in step S34 (step S35). Then, the control unit 31 displays the alarm information stored in step S35 on the display unit 34 in association with the patient-related information stored in step S35 (step S36).

[0098] Then, corresponding to step S21 in FIG. 5, the control unit 31 associates the alarm information stored in step S35 with the patient-related information stored in step S35 via the wireless communication unit 35, broadcasts the associated patient-related information and alarm information to all patient information communication devices 2 except for the patient information communication device 2 that sent the alarm information in step S34 (step S37), and proceeds to step S31.

[0099] Next, referring to Fig. 7, a measurement data display screen 200 will be described as an example of a display screen displayed by the patient information display process of Fig. 5. First, the patient information communication device 2 on which the measurement data display screen 200 is displayed is defined as the patient, and the patient who will be placed in the bed on which the patient information communication device 2 is installed is defined as the patient. The patient-related information includes the patient ID, the patient name, the patient sex, and the bed number of the bed on which the patient will be placed.

[0100] 7, the measurement data display screen 200 has a patient-related information display area 210, a measurement data display area 220, and an alarm information display area 230. The patient-related information display area 210 is a display area for the patient's own patient's patient-related information (patient ID (0001), patient name (Suzuki Jiro), gender (male), bed number (201-A)).

[0101] The measurement data display area 220 is a display area for the measurement data of the patient of the device, which is associated with the patient-related information display area 210. In the measurement data display area 220 of Fig. 7, the SpO2 and pulse rate of the patient of the device measured by the pulse oximeter 1, and the respiratory rate of the patient of the device measured by the respiratory sensor 4 are displayed as measurement waveforms.

[0102] The alarm information display area 230 is a display area for alarm information of other patients, and has a bed number 231 and an alarm type 232. The bed number 231 is the bed number of the other patient. The alarm type 232 is the alarm type of the other patient corresponding to the bed number 231, with "S" indicating SpO2 and "P" indicating pulse rate. In the alarm information display area 230 of FIG. 7, the bed number 231 indicates the SpO2 and pulse rate of four other patients, 201-B, 203-C, 205-A, and 207-B, respectively. 2、 Pulse rate, SpO 2、 This indicates that there is an abnormality in the pulse rate. There are no abnormalities in the measurement data of the patient of the device, and no equipment abnormalities have occurred in the pulse oximeter 1 of the patient of the device or any other patient.

[0103] In the nurse mode, the measurement data (measurements, measurement waveforms) of other patients displayed in the alarm information display area 230 may be displayed on the measurement data display screen 200.

[0104] As described above, according to this embodiment, the patient information communication device 2 is placed at the bedside in association with the bed where the first patient lies, and displays the biological information of the first patient on the display unit 24. The patient information communication device 2 includes a wireless communication unit 26 that receives biological information of a second patient different from the first patient from a server 3 that manages the biological information of patients, and a control unit 21 that displays the received biological information of the second patient on the display unit 24. The monitoring system 100 includes a first patient, the patient information communication device 2 of the second patient, and a server 3 that transmits the biological information of the second patient to the patient information communication device 2 of the first patient. The biological information here is information related to the patient's body, and is assumed to include at least one of the patient's measurement data, alarm information, and patient-related information.

[0105] Therefore, a user such as a nurse can visually check the biological information of a first patient, and can also visually check the biological information of a second patient, who is another patient, at the same position.

[0106] The biological information of the second patient also includes alarm information of the measurement data indicating that the measurement data of the vital values ​​of the second patient is abnormal, so that the user can visually confirm that there is an abnormality in the measurement data of the second patient.

[0107] Furthermore, the control unit 21 determines whether or not the measurement data measured by the pulse oximeter 1 that measures the measurement data of the vital values ​​of the first patient is abnormal, and if abnormal, transmits alarm information of the measurement data of the first patient to the server 3 via the wireless communication unit 26. Therefore, the server 3 can transmit the alarm information of the measurement data of the first patient to the patient information communication device 2 of the second patient to display it, and a user viewing the patient information communication device 2 of the second patient can visually confirm that there is an abnormality in the measurement data of the first patient.

[0108] The biological information of the second patient also includes alarm information of an equipment abnormality indicating an abnormality in the pulse oximeter 1 that measures the measurement data of the second patient's vital values. This allows the user to visually confirm that there is an abnormality in the pulse oximeter 1 of the second patient.

[0109] Furthermore, the control unit 21 determines whether or not the pulse oximeter 1 measuring the measurement data of the vital values ​​of the first patient is abnormal, and if abnormal, transmits alarm information of the device abnormality of the pulse oximeter 1 to the server 3 via the wireless communication unit 26. Therefore, the server 3 can transmit the alarm information of the device abnormality of the first patient to the patient information communication device 2 of the second patient to display it, and a user checking the patient information communication device 2 of the second patient can visually confirm that there is an abnormality in the pulse oximeter 1 of the first patient.

[0110] In addition, the biological information of the second patient includes patient-related information regarding the second patient, which allows the user to visually check the patient-related information of the second patient.

[0111] Furthermore, the control unit 21 displays the biological information not including the personal information of the second patient on the display unit 24. This makes it possible to prevent the first patient from accidentally viewing the personal information of the second patient.

[0112] Furthermore, the control unit 21 displays the biological information of the second patient (alarm information display area 230) together with the biological information of the first patient (patient-related information display area 210 and measurement data display area 220 of the measurement data display screen 200 in FIG. 7) on the display unit 24. This allows the user to visually check the biological information of the first patient and the biological information of the second patient at the same time.

[0113] Furthermore, the control unit 21 notifies the user that the biological information of the second patient has been received (displayed) by sound output and vibration output from the output unit 29. This allows the user to reliably check the biological information of the second patient.

[0114] Moreover, wireless communication unit 26 uses sub-gigabit wireless. Therefore, sub-gigabit wireless can transmit radio waves over a relatively long distance, so fewer repeaters are required, which improves ease of installation of equipment and makes it difficult for radio wave contention to occur, unlike wireless at 2.4 GHz or the like.

[0115] The above description of the embodiment is merely an example of a suitable biological information display device, a biological information display system, and a program according to the present invention, and the present invention is not limited to this.

[0116] For example, in the above embodiment, the alarm information of other patients is notified by each patient information communication device 2, but the present invention is not limited to this. For example, each user may carry an MT (not shown) connected to an earphone, wear the earphone, and when alarm information of another patient occurs, the server 3 may transmit the alarm information of the other patient to the MT and output the sound via the earphone.

[0117] In addition, the patient information communication device 2 is configured to be installed at the bedside of the bed where the patient lies, but the present invention is not limited to this. The patient information communication device 2 may be configured to be placed or installed on a movable wagon. In this configuration, even if the display screen of the display unit 24 of the patient information communication device 2 is small or even in a corridor or the like where the patient is moving from the bed, alarm information is notified and the user can confirm it visually and audibly.

[0118] In addition, the MT may be a wearable portable terminal such as a wristwatch type or goggle type, and the server 3 may transmit alarm information and patient-related information corresponding to the patient's alarm information and terminal information transferred from the patient information communication device 2 to the MT, thereby notifying the patient of the alarm information and patient-related information.

[0119] In addition, a commonly viewable display device may be provided in each hospital room, and the server 3 may transmit alarm information and patient-related information corresponding to the patient's alarm information and terminal information transferred from the patient information communication device 2 to the display device, thereby displaying the alarm information and patient-related information.

[0120] In the above embodiment, the control unit 21 of the patient information communication device 2 determines whether the measurement data measured by the pulse oximeter 1 is abnormal, but the present invention is not limited to this. For example, the control unit 31 of the server 3 may determine whether the measurement data received from the patient information communication device 2 is abnormal, and if abnormal, generate alarm information for the corresponding measurement data, and broadcast the generated alarm information for the measurement data via the wireless communication unit 35 to patient information communication devices 2 other than the patient information communication device 2 that sent the data, for display and notification.

[0121] In the above embodiment, the pulse oximeter 1 is described as a measuring device for measuring vital value measurement data, but the present invention is not limited to this. The measuring device may be configured to be applied to various sensors that detect measurement data of vital values ​​other than SpO2 and pulse rate.

[0122] Furthermore, the detailed configurations and operations of the components constituting the monitoring system 100 in the above embodiment may be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
