  2. Description of the Related Art Conventionally, a biological information monitor is known as a patient monitoring device for monitoring the state of a patient who is receiving treatment in an intensive care unit or the like. In this biological information monitor, biological information such as a patient's pulse wave, pulse rate, blood pressure, and respiratory rate is monitored via a sensor attached to the patient. In such a biological information monitor, there is known a biological information monitor that can display a demonstration screen for the purpose of exhibition or education of medical staff.

  FIG. 15 is a diagram illustrating an appearance of a conventional biological information monitor having a demonstration screen.

  The biological information monitor 150 shown in FIG. 15 includes a display unit 152, an electrocardiogram input connector 13, a blood pressure input connector 14, an oxygen saturation input connector 15, and a body temperature input connector 16 provided below the display unit 152. , A non-invasive blood pressure connection joint 17 and a carbon dioxide concentration input connector 18 are provided. The electrocardiogram input connector 13, the invasive blood pressure input connector 14, the oxygen saturation input connector 15, the body temperature input connector 16, the non-invasive blood pressure connection joint 17, and the carbon dioxide concentration input connector 18 monitor the patient's biological information. Therefore, an electrocardiogram relay cable, an invasive blood pressure relay cable, an oxygen saturation sensor cable, a body temperature probe, a cuff tube for non-invasive blood pressure measurement, and a carbon dioxide concentration relay cable are connected. In addition, diversity antennas 19a and 19b constituting a tele control unit are provided on the rear surface.

  Here, in a state where nothing is connected to the above-described connector or joint, the demo mode is selected by operating a menu button provided at the bottom of the display unit 152. Then, biological parameters such as electrocardiogram, respiration, and oxygen saturation are displayed on the display unit 152 as waveforms and numerical values. For this reason, it can appear as if the patient is being monitored. Further, a character string 153 such as “DEMO” is displayed on the upper left of the display unit 152 in order to notify that the demo mode has been selected.

There has also been proposed a biological information monitor that inputs biological information such as an electrocardiogram and blood pressure, amplifies the inputted biological information, performs modulation processing, and transmits the information wirelessly (see Patent Document 1). According to this biological information monitor, the biological information of the patient can be transmitted to the central monitor that manages the biological information of the patient.
Japanese Utility Model Publication No. 07-22702

  In a conventional biological information monitor having a demo screen, the demo mode is selected and a character string such as “DEMO” is displayed on the screen, but a cable or the like is connected to an input connector or the like provided in the biological information monitor. If is connected, the patient's biological information may be monitored. On the contrary, if the demo mode is selected while the patient's biological information is being monitored, the demo mode may be entered. Therefore, there is a problem that the patient is exposed to danger because not only the convenience of the biological information monitor is bad but also the change of the patient's condition cannot be grasped. Furthermore, in such a central monitor having a demo screen while managing the biological information of the patient by acquiring the biological information output from the bedside monitor which is a biological information monitor for monitoring the biological information of the patient, The problem described above may occur.

FIG. 5 is a diagram showing a dialog of a patient cable connection warning menu displayed on the display unit. Further, FIG. 6 is a diagram showing a screen of the demo mode displayed on the display unit.

  When the operator touches the touch panel arranged on the front surface of the display unit 12, a hardware interrupt is generated and a key input interrupt routine shown in FIG. 4 is started.

  First, in step S101, the input key is determined from the currently displayed menu and the position information touched by the operator.

  Next, in step S102, it is determined whether or not the key for entering the demo mode has been pressed. If it is determined that the key to enter the demo mode has not been pressed, the process proceeds to another process. On the other hand, if it is determined that the key for entering the demo mode has been pressed, the process proceeds to step S103.

  In step S103, it is determined whether or not a patient cable is connected. If it is determined that the patient cable is connected, the process proceeds to step S104.

  In step S104, a dialog of a patient cable connection warning menu shown in FIG. 5 described below is displayed on the display unit 12, and this routine is terminated. In FIG. 5, a dialog D01 of a patient cable connection warning menu is displayed. This dialog D01 shows a message M01 indicating that the demo mode cannot be entered unless the patient cable is disconnected. Pressing the OK button B01 at the bottom of this dialog D01 returns to the original screen.

  On the other hand, if it is determined in step S103 that the patient cable is not connected, the process proceeds to step S105. In step S105, the demo mode is entered without opening any dialog or window, and the pseudo waveform or numerical value shown in FIG. 6 is displayed and the routine is terminated. FIG. 6 also shows a non-invasive blood pressure measurement button B02 described later.

  Next, the operation when the patient cable is connected will be described with reference to FIGS. 7, 8, and 9.

  FIG. 7 is a diagram showing a flow of a patient cable connection interrupt routine that is started when a patient cable is connected. FIG. 8 is a diagram showing a dialog of a normal mode return menu displayed on the display unit. Furthermore, FIG. 9 is a figure which shows the entrance window displayed on the display part.

  When the operator inserts a cable corresponding to any of the electrocardiogram input connector 13, the blood pressure input connector 14, the oxygen saturation input connector 15, the body temperature input connector 16, and the carbon dioxide concentration input connector 18, a hardware interrupt is applied. This activates the patient cable connection interrupt routine. First, in step S201, it is acquired whether the biological information monitor 1 is currently operating in the normal mode or the demo mode.

  Next, in step S202, it is determined whether or not the current mode is the demo mode. If it is determined that the current mode is not the demo mode, this routine is terminated. On the other hand, if it is determined that the current mode is the demo mode, the process proceeds to step S203.

  In step S203, the normal mode return menu dialog D02 shown in FIG. 8 is displayed on the display unit 12, and a message M02 in the dialog D02 informs the operator that the normal mode is to be restored. If the OK button B03 at the bottom of the dialog D02 is pressed here, the process proceeds to step S204.

  In step S204, the process proceeds to the normal mode entry window W01 shown in FIG. 9, prompting the patient information to be connected from now on, and ending this routine.

  Next, an operation when the non-invasive blood pressure measurement button B02 (see FIG. 6) is pressed in the demonstration mode will be described with reference to FIG.

  FIG. 10 is a diagram showing a flow of a preprocessing routine for noninvasive blood pressure measurement.

  When the operator presses the non-invasive blood pressure measurement button B02, this pre-processing routine for non-invasive blood pressure measurement is activated. In this routine, first, in step S301, it is acquired whether the biological information monitor 1 is currently operating in the normal mode or the demo mode.

  Next, in step S302, it is determined whether or not the current mode is the demo mode. If it is determined that the current mode is not the demo mode, this routine is terminated. Thereafter, non-invasive blood pressure measurement is performed. On the other hand, if it is determined that the current mode is the demo mode, the process proceeds to step S303.

  In step S303, the normal mode return menu dialog D02 shown in FIG. 8 is displayed on the display unit 12, and a message M02 of the dialog D02 notifies the operator that the normal mode is to be restored. If the OK button B03 at the bottom of the dialog D02 is pressed here, the process proceeds to step S304.

  In step S304, the process proceeds to the above-described normal mode entrance window W01 shown in FIG. 9, prompting the input of patient information to be connected to the patient cable, and ending this routine. Thereafter, non-invasive blood pressure measurement is performed.

  Since the non-invasive blood pressure connection joint 17 to which the non-invasive blood pressure measurement cuff tube 27 is connected does not have an electrical contact, it will be described with reference to the flowchart of the patient cable connection interruption routine shown in FIG. Hardware interrupt does not occur like the connector that I did. Therefore, when the current mode is the demo mode, the non-invasive blood pressure measurement is performed by exiting from the demo mode when the operator presses the non-invasive blood pressure measurement button B02 to display the intention of measurement. In the above embodiment, an example in which a dialog is displayed before returning to the normal mode has been described. However, this may be omitted and an entry window may be displayed.

  First, in step S401, a communication packet is acquired.

  Next, in step S402, the packet is decoded and analyzed.

  In step S403, as a result of analyzing the packet, if the flag indicating that the biometric information monitor 1 as the communication source is in the demo mode is not set, this routine is terminated as it is, and the next processing is started. .

  On the other hand, if the flag is set, the process proceeds to step S404. Here, as shown in FIG. 13, biological information for eight floors is displayed on the corresponding floor (the entrance window displayed on the display unit 112 of the central monitor 1 shown in FIG. 14). 1 floor (indicated by BED-001) displays the message M03 “currently in demo mode” and the entry button B03, and does not display any data such as waveforms or numerical values, and terminates this routine. To do.

  In this state, the entry button B03 is pressed. Then, as shown in FIG. 14, the patient entry window W02 is opened, and the patient entry process can be performed. After entering the floor, the non-invasive blood pressure can be measured by remote control through the telecontrol units 19 and 119.

  In the above-described embodiment, the example in which the biological information monitor and the central monitor communicate with each other wirelessly has been described.
