  In a medical field such as a hospital, it is necessary to collect, analyze, and display biometric information (for example, electrocardiogram, blood pressure, number of breaths, and pulse) of each patient as needed. In addition, since the patient is transferred to a hospital room, examination room, operating room, etc., it is necessary to collect the patient's biological information together with the transfer of the patient. Small medical portable monitor systems (see, for example, Patent Documents 1 and 2) are widely used.

  As this type of system, there is a system in which a portable transport monitor can be connected to a stationary bedside monitor (specifically, dockable and removable). This kind of bedside monitor can also be called a host monitor for a transport monitor.

  The transport monitor has a terminal unit to which an electrocardiogram measurement electrode and the like are connected, a small display, a data storage device, a battery, and the like, and acquires and displays and records biological information without interruption even while the patient is transported. be able to. The biological information recorded on the transport monitor during the transfer of the patient is transferred to the bedside monitor when the transport monitor is docked on the bedside monitor. The biological information transferred to the bedside monitor is also sent to the central monitor connected to the bedside monitor.

  By using such a system having a transport monitor, it is possible to easily acquire the biological information of the patient being transferred. In addition, since the transport monitor is docked to the bedside monitor, the biometric information acquisition electrode attached to the patient can be connected without reconnection between the bedside monitor and the transport monitor. Measurement of biological information can be continued by simply plugging / unplugging the port monitor into / from the bedside monitor.

<1> Overall Configuration First, the overall configuration and the premise configuration of the embodiment will be described.

  FIG. 1 is a diagram showing how the bedside monitors 11 and 12 and the transport monitor 20 are docked (connected). Although not shown here, the transport monitor 20 is connected to a biological information detection unit for acquiring patient biological information such as an electrocardiogram measurement electrode.

  When a patient is transferred from a place where the bedside monitor 11 is placed to a place where the bedside monitor 12 is placed, a medical worker such as a doctor or a nurse removes the transport monitor 20 from the bedside monitor 11. (FIG. 1A) After the transport monitor is moved together with the patient (FIG. 1B), the transport monitor 20 is docked on the bedside monitor 12 (FIG. 1C). By doing so, the patient's biological information can be acquired by the transport monitor 20 even during transfer of the patient.

  Here, the bottom and side surfaces of the transport monitor 20 and the surfaces of the bedside monitors 11 and 12 corresponding thereto are provided with connector portions that are electrically connected to each other when docked. The port monitor 20 and the bedside monitors 11 and 12 can transmit and receive information such as biological information and setting information to each other via the connector unit.

  The characteristics of each device when the bedside monitors 11 and 12 and the transport monitor 20 are compared with each other are as follows.

Bedside monitor:

  Note that the bedside monitor and the transport monitor do not necessarily have all of the above features, but at least the transport monitor is configured to be smaller and lighter than the bedside monitor and can be carried.

  FIG. 2 is a diagram showing a schematic configuration of an in-hospital system (hereinafter referred to as “in-hospital system”) 10 to which the bedside monitor and the transport monitor of the present embodiment are connected. In the hospital system 10, one or more bedside monitors 11A to 11X are installed in an operating room, one or more bedside monitors 12A to 12X are installed in an ICU (Intensive Care Unit), and one or more bedside monitors are installed in a ward. Bedside monitors 13A to 13X are installed. Note that the “ward” described in this specification is a so-called “general ward” excluding a special treatment room such as an operating room or an ICU.

  The bedside monitors 11A to 11X in the operating room are connected to the central monitor 31, the bedside monitors 12A to 12X in the ICU are connected to the central monitor 32, and the bedside monitors 13A to 13X in the ward are connected to the central monitor 33. It is connected.

  Further, the central monitors 31, 32, 33 are connected to the server device 40. Thereby, the biological information acquired by the bedside monitors 11A to 11X is collected and displayed and recorded on the central monitor 31, and the biological information acquired by the bedside monitors 12A to 12X is collected to the central monitor 32. Display and recording are performed, and the biological information acquired by the bedside monitors 13A to 13X is collected on the central monitor 33 and displayed or recorded. In addition, the biological information acquired by the central monitors 31, 32, and 33 is collected and recorded in the server device 40. The server device 40, for example, records the biological information in response to requests from the central monitors 31, 32, 33 and bedside monitors 11A-11X, 12A-12X, 13A-13X, and the central monitors 31, 32, 33 and bedside monitors. 11A to 11X, 12A to 12X, and 13A to 13X.

  The transport monitor 20 can be docked (connected) to each of the bedside monitors 11A to 11X, 12A to 12X, and 13A to 13X, moves with the patient, and the bedside monitors 11A to 11X to which the patient has been transferred. , 12A to 12X and 13A to 13X.

  Although FIG. 2 shows the hospital system 10, the transport monitor 20 can be docked (connected) to, for example, a bedside monitor provided in an ambulance.

<2> Configuration of Bedside Monitor FIG. 3 is a block diagram showing the configuration of the bedside monitor 100 of the present embodiment. The bedside monitor 100 is used as the bedside monitors 11A to 11X, 12A to 12X, and 13A to 13X in FIGS.

  The bedside monitor 100 has connector portions 101, 102, and 103.

The connector unit 101 is a connector for connecting a biological information detection unit attached to a patient to the bedside monitor 100. The connector portion 101, SpO ₂ sensor for detecting electrocardiogram measurement electrode 201 for detecting an electrocardiogram, blood pressure cuff 202 for detecting the blood pressure, body temperature sensor 203, SpO ₂ for detecting the temperature 204, and a biological information detection unit such as a cardiac output sensor 205 for detecting the cardiac output are connected.

  The transport monitor 20 is connected to the connector unit 102. The central monitor 30 is connected to the connector unit 103.

The measurement processing unit 104 executes a predetermined measurement process to thereby detect a biological information detection unit (an electrocardiographic electrode 201, a blood pressure measurement cuff 202, a body temperature sensor 203, an SpO ₂ sensor 204, and a heart rate) connected to the connector unit 101. The patient's biological information is measured using the output sensor 205). In addition, since the conventionally well-known thing is applicable about the measuring method of various biological information using the said biological information detection part, the detailed description is abbreviate | omitted here. The biological information obtained by the measurement processing unit 104 is stored in the storage unit 105 and displayed on the touch panel 109.

  On the other hand, the biological information acquired by the transport monitor 20 is stored in the storage unit 105 via the connector unit 102 and the transmission / reception processing unit 106. Incidentally, the biological information acquired by the transport monitor 20 during the movement of the transport monitor 20 is temporarily stored in a storage unit (not shown) of the transport monitor, and when connected to the bedside monitor 100, the connector unit. The data is transferred and stored in the storage unit 105 of the bedside monitor 100 via the communication unit 102 and the transmission / reception processing unit 106.

  The biological information stored in the storage unit 105 is sent to the central monitor 30 via the transmission / reception processing unit 106 and the connector unit 103. Thereby, the central monitor 30 can display and record the biological information acquired by the bedside monitor 100 and the transport monitor 20.

  The control unit 110 controls the measurement processing unit 104, the transmission / reception processing unit 106, the display control unit 107, and the alarm indicator 108.

  The touch panel 109 is controlled by the display control unit 107 and displays biological information in the form of measurement values or waveforms. The touch panel 109 not only has a display function for displaying biological information, but also has a function as an operation input unit that receives an input operation by an operator. Specifically, information indicating the touch operation of the user on the touch panel 109 is sent from the touch panel 109 to the control unit 110, and the control unit 110 changes the display on the touch panel 109 or the mode of the bedside monitor 100 according to the touch operation. Perform various registration processes.

  The alarm indicator 108 is provided on the upper part of the casing of the bedside monitor 100 and emits red light, for example, when the control unit 110 determines that an abnormality has occurred in the biological information.

  The bedside monitor 100 includes a connection detection unit 111 and an ID identification unit 112. The connection detection unit 111 detects whether the transport monitor 20 is connected to the connector unit 102 and sends the detection result to the control unit 110. The ID identification unit 112 inputs the patient ID set in the transport monitor 20 connected to the connector unit 102 via the connector unit 102, and the patient ID of the transport monitor 20 to which this patient ID was previously connected. And the identification result is sent to the control unit 110.

  When the transport monitor 20 is removed from the bedside monitor 100, this is detected by the connection detection unit 111, and the screen shown in FIG. 4 is displayed on the touch panel 109. When the “monitor interruption” button is touched by the user (healthcare professional), the bedside monitor 100 enters a monitoring interruption mode, and the monitoring of biological information is interrupted. On the other hand, when the “Leave” button is touched by the user, the bedside monitor 100 performs the exit process.

  When the transport monitor 20 is connected to the bedside monitor 100, this is detected by the connection detection unit 111, and the patient selection screen shown in FIG. 5 is displayed on the touch panel 109. In this screen, the user uses the patient information associated with the patient ID set in the transport monitor 20 and the patient associated with the patient ID set in the apparatus (bedside monitor 100). Either a mode using information or a mode in which patient information is newly input and monitoring is started can be selected.

<3> Display of Biometric Information According to Embodiment FIG. 6 is a diagram for explaining a display method of biometric information performed by the bedside monitor 100 of the present embodiment. In FIG. 6, in order to simplify the drawing, the time direction is shown shorter than the actual time.

  FIG. 6A shows an electrocardiographic waveform obtained when the transport monitor 20 is docked (connected) to the bedside monitor 100. This electrocardiographic waveform is stored in the storage unit 105 of the bedside monitor 100.

  FIG. 6B is an electrocardiographic waveform acquired by the transport monitor 20 in a state where the transport monitor 20 is removed from the bedside monitor 100. This electrocardiographic waveform is stored in a storage unit (not shown) of the transport monitor 20.

  FIG. 6C shows an electrocardiographic waveform displayed on the bedside monitor 100 after the transport monitor 20 is re-docked (reconnected) to the bedside monitor 100. As can be seen from FIG. 6C, in the bedside monitor 100, the electrocardiogram waveform obtained when the transport monitor 20 is connected (the electrocardiogram waveform of FIG. 6A) and the transport monitor 20 are not connected. Then, the electrocardiogram waveform acquired by the transport monitor 20 (the electrocardiogram waveform in FIG. 6B) is connected and displayed on the same time axis.

  In addition, the bedside monitor 100 includes the electrocardiogram waveform acquired when the transport monitor 20 is connected (the electrocardiogram waveform of FIG. 6A) and the transport monitor 20 when the transport monitor 20 is not connected. Marks 301 and 302 indicating positions where the electrocardiogram waveform obtained in step (the electrocardiogram waveform in FIG. 6B) is connected are displayed. The position with the mark 301 is a position corresponding to the time t1 when the transport monitor 20 is removed from the bedside monitor 100, and the position with the mark 302 is attached to the bedside monitor 100 again. This is the position corresponding to the time point t2 (reconnected). By displaying the marks 301 and 302, the medical staff can easily recognize from where to where the electrocardiographic waveform is the waveform acquired by the transport monitor 20 during the transfer of the patient. In particular, in the present embodiment, triangular figures are used as the marks 301 and 302, and the apexes thereof face the direction of the waveform section acquired by the transport monitor 20 during the transfer of the patient. The waveform section acquired during movement can be recognized.

  Furthermore, in the present embodiment, as can be seen from FIG. 6C, mask sections 401 and 402 are provided at the joints instead of simply connecting the electrocardiogram waveform of FIG. 6A and the electrocardiogram waveform of FIG. 6B to the heart of FIG. The radio wave shape and the electrocardiogram waveform of FIG. 6B are connected. By doing so, there is a difference between the machine time of the bedside monitor 100 and the machine time of the transport monitor 20, and the two electrocardiographic waveforms to be connected are relatively shifted in the time direction. Even in the electrocardiographic waveform obtained by connecting two electrocardiographic waveforms, inconvenience due to the difference in the mechanical time can be suppressed.

  Specifically, if two electrocardiographic waveforms are connected without providing the mask sections 401 and 402, the waveform is displayed as if the waveform fluctuates due to the difference in machine time at the joint position. End up. Although this waveform fluctuation is not an actual disturbance of the electrocardiogram waveform, the doctor may misunderstand that the electrocardiogram waveform is disturbed and diagnose it as an abnormality such as arrhythmia. By providing the mask sections 401 and 402 as in the present embodiment, such a misdiagnosis can be prevented in advance. Incidentally, in reality, it is assumed that a difference of about several milliseconds occurs between the machine time of the bedside monitor 100 and the machine time of the transport monitor 20. In consideration of this, it is preferable that the mask sections 401 and 402 each be about several msec or more.

  In practice, the processing for connecting the two electrocardiographic waveforms on the same time axis, the processing for adding the marks 301 and 302, and the processing for providing the mask sections 401 and 402 as described above are performed by the display control unit 107. .

  Incidentally, in this embodiment, when connecting two electrocardiographic waveforms, the ID identification unit 112 identifies and displays the patient ID set in the bedside monitor 100 and the patient ID set in the transport monitor 20. The control unit 107 connects the electrocardiographic waveforms of the monitors identified by the ID identifying unit 112 as the same patient ID. Thereby, for example, even if the transport monitor 20 of a patient different from the previous patient is connected to the bedside monitor 100, it is possible to prevent the inconvenience of connecting those electrocardiographic waveforms.

  In the above-described embodiment, the electrocardiogram waveform acquired when the transport monitor 20 is connected (the electrocardiogram waveform of FIG. 6A) and the transport monitor 20 without the transport monitor 20 connected. Although the case where a triangular figure is displayed as the marks 301 and 302 indicating the position where the acquired electrocardiogram waveform (electrocardiogram waveform in FIG. 6B) is connected has been described, the mark is not limited thereto. For example, as shown in FIG. 7, it may be used as a mark to clearly display that it is a movement period. Further, as shown in FIG. 8, the marks 301 and 302 may be omitted by using the mask sections 401 and 402 as marks.

<4> Effects of the Embodiment As described above, according to the present embodiment, the bedside monitor 100 is configured such that the electrocardiogram waveform (cardiac radio wave in FIG. 6A) acquired with the transport monitor 20 connected. ) And the electrocardiogram waveform acquired by the transport monitor 20 in a state where the transport monitor 20 is not connected (the electrocardiogram waveform of FIG. 6B) are displayed on the same time axis, and the transport The electrocardiogram waveform obtained when the monitor is connected (the electrocardiogram waveform shown in FIG. 6A) and the electrocardiogram waveform obtained by the transport monitor 20 when the transport monitor 20 is not connected (the heart shown in FIG. 6B). Marks 301 and 302 indicating positions where the radio wave shape) is connected are displayed. Thereby, it is possible to realize the bedside monitor 100 that can display a series of biological information of the patient including the moving biological information acquired by the transport monitor 20 in a form that can be easily diagnosed.

  The above-described embodiments are merely examples of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or main features thereof.

  The display of the electrocardiographic waveform in the above-described embodiment is not limited to the bedside monitor, and may be performed by a central monitor. That is, the display method of the present invention is a display method used in a biological information monitoring system having a bedside monitor and a portable transport monitor that can be connected to the bedside monitor. The first biological information (FIG. 6A) is acquired by the bedside monitor and the transport monitor in a state where the monitor is connected, and the second biological body is detected by the transport monitor in a state where the transport monitor is not connected. Acquiring the information (FIG. 6B), displaying the first biological information and the second biological information on the same time axis (FIG. 6C), and displaying the first biological information and the first biological information. Displaying a mark indicating the position where the two pieces of biological information are connected (FIG. 6C). It is sufficient.

  In the above-described embodiment, the electrocardiogram waveform is exemplified as the biometric information to be connected and displayed. However, the biometric information to be connected and displayed is not limited to the electrocardiogram waveform, and may be, for example, a waveform of oxygen saturation or blood pressure.

  The present invention is widely applicable to a display method used in a biological information monitoring system having a bedside monitor to which a transport monitor can be connected and a bedside monitor and a portable transport monitor that can be connected to the bedside monitor. It is.

  Further, the transport monitor of the above-described embodiment can be read as a telemeter. That is, the transport monitor of the present invention means a movable biological information measuring device that can be connected to a bedside monitor.

  The present invention provides the first biological information acquired when the transport monitor is connected to the connection unit, and the second biological information acquired by the transport monitor when the transport monitor is not connected to the connection unit. This is widely effective when information is connected and displayed. The second biological information in the above-described embodiment is stored in the memory of the transport monitor during movement, and transferred to the bedside monitor when the transport monitor is connected to the bedside monitor. . However, for example, when the transport monitor is a telemeter, the second biological information may be wirelessly transmitted to the central monitor while the telemeter is moving. The second biological information wirelessly transmitted to the central monitor is sent to the bedside monitor, and connected to the first biological information on the same time axis by the bedside monitor by the method described above.
