Description

  The present invention relates to a biological information monitor.

  The biological information monitor can measure biological information such as an electrocardiogram, blood pressure, and oxygen saturation, and can collectively display the measured values and waveforms on the display. Examples of the biological information monitor include a bedside monitor that is installed and used on the bedside of a hospital room or a central monitor that is installed and used on a nurse station.

  By looking at the measurement values and waveforms displayed on the biological information monitor, a health care worker (such as a doctor or a nurse) can grasp the patient's condition. In addition, since the biological information monitor generally has an alarm function for notifying an abnormality by an alarm sound or the like when an abnormality of a measurement value occurs, a medical worker can immediately know the abnormality of the patient.

  Patent Document 1 discloses a biological information monitor having a monitoring interruption function. When the patient who is monitoring the biological information temporarily gets out of bed for an examination or the like, the biological information monitor interrupts the monitoring in order to prevent unnecessary data from being taken in or an erroneous alarm. The biological information monitor disclosed in Patent Document 1 has a timer function so that the patient will not forget to resume monitoring even if the patient has returned, and will not miss a sudden change in the patient. In other words, if the monitor does not resume by a predetermined time, an audible sound is generated by this timer function.

Japanese Patent No. 5290108

  However, in the first place, the monitoring interruption function is a function to interrupt monitoring while the patient temporarily leaves the biological information monitor. If the patient does not return after this time, there is a drawback that an arousing sound will be generated and a troublesome operation of extending the interruption time will be required. In addition, if the patient returns earlier than the scheduled time and forgets to resume monitoring, there is a drawback in that there is a risk that the patient is not monitored until the beep sound is heard.

  The present invention has been made in consideration of the above points, and an object of the present invention is to provide a biological information monitor capable of performing interruption processing without impairing the original biological information monitoring function.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the biological information monitor 100 of the present embodiment. The biological information monitor 100 includes a connector unit 101. The connector unit 101 is a connector for connecting the biological information detection unit attached to the patient to the biological information monitor 100. A biological information measuring device group 110 is connected to the connector unit 101. The biological information measuring device group 110 includes an electrocardiogram electrode 111 for detecting an electrocardiogram, a blood pressure measurement cuff 112 for detecting blood pressure, a body temperature sensor 113 for detecting body temperature, and SpO ₂ for detecting SpO _{2. 2} sensor 114, and a biological information detection unit such as a cardiac output sensor 115 for detecting cardiac output. The connector unit 101 functions as an interface between the biological information measuring device group 110 and the control unit 102.

  The control unit 102 executes the program stored in the storage unit 103 to execute overall control of the biological information monitor 100 and predetermined measurement processing. With this measurement process, the control unit 102 measures the biological information of the patient using the biological information measuring device group 110 connected to the connector unit 101. In addition, since the conventionally well-known thing is applicable about the measuring method of various biological information using the said biological information measuring device group 110, the detailed description is abbreviate | omitted here.

  The display 104 displays the biological information obtained by the measurement process of the control unit 102 in the form of measurement values or waveforms. The display 104 is a liquid crystal display with a touch panel, for example, and has not only a display function for displaying biological information but also a function as an input unit that receives an input operation by an operator. Specifically, the display 104 can change the display format of the display 104, the mode of the biological information monitor 100, and the like according to the touch operation by the operator.

  Furthermore, the biological information monitor 100 has an operation button 120. The operation button 120 is provided in the vicinity of the display 104 on the front surface of the biological information monitor 100 as shown in FIG. 2 is an external view of the biological information monitor 100 as viewed from the front. An alarm indicator 105 is provided on the top of the housing of the biological information monitor 100. The alarm indicator 105 emits red light, for example, when the control unit 102 (FIG. 1) detects that abnormality has occurred in the biological information.

  The operation button 120 includes a plurality of buttons. Examples of the operation button 120 include a power switch 121, a measurement start / stop button 122, a data recording button 123, an alarm sound stop button 124, and the like.

  In the present embodiment, an interruption button 125 is provided as one of the operation buttons 120. When the interruption button 125 is pressed, the biological information monitor 100 interrupts monitoring of biological information.

  Here, the interruption of monitoring in the biological information monitor 100 of the present embodiment means interruption of measurement processing by the control unit 102, interruption of display of biological information on the display 104, interruption of alarm, and / or recording of biological information. Mean interruption.

  In the present embodiment, even when a monitoring interruption operation is performed by the user, the control unit 102 performs monitoring (sensing) of input of each biological information to the connector unit 101 without interruption. Yes. When the control unit 102 detects that any biological information is input after the interruption button 125 is pressed, the control process is resumed.

  The biological information monitor 100 can communicate with other biological information monitors via the communication unit 106. Specifically, the biological information monitor 100 can transmit the acquired biological information, the state of the device itself, and the like to the central monitor or the like via the communication unit 106. Further, a control signal from the central monitor can be input via the communication unit 106. Therefore, the interruption process of the biological information monitor 100 can be performed by inputting an interruption control signal from the central monitor.

  FIG. 3 shows a processing procedure of interruption processing according to this embodiment. When the process starts in step S0, the control unit 102 performs a normal monitoring process in step S1, and determines whether or not an interruption operation has been performed in the subsequent step S2. Specifically, the control unit 102 determines whether or not there is an interruption operation by detecting whether or not the interruption button 125 is pressed or an interruption control signal is input from the central monitor. When it is determined that there is no interruption operation (step S2; NO), the process returns to step S1 to continue the normal monitoring process.

  On the other hand, when the control unit 102 determines that there is an interruption operation (step S2; YES), the control unit 102 moves to step S3 and performs interruption processing. Specifically, as described above, the measurement processing of the biological information is interrupted, the display of the biological information on the display 104 is interrupted, the alarm is interrupted, or the recording of the biological information is interrupted.

  Next, in step S <b> 4, the control unit 102 determines whether any biological information is input to the connector unit 101. When it is determined that there is no input of any biological information (step S4; NO), the control unit 102 returns to step S3 and continues the interruption process.

  On the other hand, when it is determined that any biological information is input (step S4; YES), the control unit 102 proceeds to step S5 to perform monitoring resumption processing, and proceeds to step S1.

  According to the present embodiment, the resumption of the suspended monitoring is controlled based on the presence / absence of the input of the biological information signal to be monitored from the biological information measuring device group 110, so that the patient Upon returning to the information monitor and mounting any one of the biological information measuring device groups 110, the monitoring can be automatically resumed, and as a result, an interruption process is performed without impairing the original biological information monitoring function. Will be able to.

  That is, in the biological information monitor 100 according to the present embodiment, the patient can return to the patient only by interrupting the monitoring when the patient leaves the bed without estimating the scheduled time for the patient to return and setting the monitoring interruption time. Monitoring can be resumed automatically as soon as possible. In addition, even if the patient does not return to the scheduled time, it is possible to save the trouble of extending the interruption time, and when the patient returns earlier than the scheduled time, the risk of forgetting to resume and not being temporarily monitored can be eliminated. .

  FIG. 4 shows a relationship between an interruption operation and an alarm under a situation where an abnormality occurs in a monitored patient when a conventional apparatus configuration is used. Case 1 is a case where an interruption operation is performed on both the bedside monitor and the central monitor. In this case, no alarm is output on the bedside monitor and the central monitor. Case 2 is a case where an interruption operation is performed on the bedside monitor and no interruption operation is performed on the central monitor. In this case, no alarm is output on the bedside monitor and an alarm is output on the central monitor. . Case 3 is a case where the interruption operation is not performed on the bedside monitor but the interruption operation is performed on the central monitor. In this case, an alarm is output on the bedside monitor and no alarm is output on the central monitor. Case 4 is a case where no interruption operation is performed on both the bedside monitor and the central monitor. In this case, an alarm is output on the bedside monitor and the central monitor.

  In other words, Case 1 is a case where, for example, a patient leaves the bed and monitoring is interrupted by both the bedside monitor and the central monitor. Case 2 is a case where, for example, monitoring is interrupted only by the bedside monitor when the patient leaves the floor. Yes, Case 3 is for example when the patient returns and resumes monitoring only at the bedside monitor and forgets to restart at the central monitor, and Case 4 is for example when the patient is not getting out of bed or when the patient returns This is when monitoring is resumed on both the side monitor and the central monitor.

  The most problematic case is Case 3. In case 3, although the patient's condition has deteriorated, it is not output by the central monitor, so the medical staff cannot rush under the patient. As described above, when the bedside monitor and the central monitor adopt a system capable of performing an interruption operation independently, there is a possibility that the response to a patient whose condition has deteriorated may be delayed. However, if the monitoring of the central monitor is resumed when a signal of biological information to be monitored is input to the interrupted central monitor, the inconvenience as in case 3 can be avoided. The present invention can achieve a great effect when applied to a central monitor. That is, the biological information monitor of the present invention includes a central monitor.

  Incidentally, in the past, although a patient was monitoring with a biological information monitor (bedside monitor), monitoring was sometimes accidentally interrupted with a central monitor. If the biological information monitor 100 according to the embodiment is used, the monitoring is automatically resumed when the biological information is input. Therefore, even if the monitoring is interrupted by mistake, the biological information is input. As long as monitoring is resumed. Therefore, it is possible to avoid the risk that monitoring is interrupted due to an erroneous interruption operation.

  In the above-described embodiment, the case where the resumption of the suspended monitoring function is controlled by performing the process of FIG. 3 has been described. However, by performing the process of FIG. The interruption of the monitoring function may be controlled based on whether or not a signal is input from the measuring device. Specifically, the interruption process is performed only when there is an interruption operation (step S2; YES) and no biometric information is input (step S4; NO). In other words, even if an interruption operation is performed, if any biological information is input (step S4; YES), the interruption process is not performed. In this way, even if the monitoring interruption operation is mistakenly performed by the user, the interruption operation can be invalidated.

  Here, in the biological information monitor 100, input of biological information from the biological information measuring device group 110 is also made on the assumption that an unintentional electrode disconnection (may be referred to as connector disconnection) of the biological information measuring device group 110 is assumed. All monitoring interruptions are not automatically controlled only by the presence or absence. In other words, if there is no input of biological information from the biological information measuring device group 110, if the interruption control is automatically performed, the monitoring is interrupted when an unintentional electrode detachment is caused, which is inconvenient. . In the present invention, in consideration of such points, the interruption is started by the interruption operation unit, and only the interruption is restarted based on the input of biological information from the biological information measuring device group 110.

  The embodiment of the present invention has been described above. The above description is an illustration of a preferred embodiment of the present invention, and the scope of the present invention is not limited to this. That is, the description of the configuration of the apparatus and the shape of each part is an example, and it is obvious that various modifications and additions to these examples are possible within the scope of the present invention.

  The present invention can be widely applied to a biological information monitor having a monitoring interruption function.
