Description

The present invention relates to a notification system.

Conventionally, there is known a technique of acquiring biological information from a patient in a hospital bed and outputting an alarm sound because there is a risk to the patient's biological body when the measured value of the biological information deviates from the set range. .. The alarm sound is output to call the staff (nurse, caregiving staff, etc.) from the nurse station or the like.

However, the measured value of the acquired biometric information may suddenly increase (or sharply decrease) due to factors such as noise. In this case, the measured value deviates from the set range, and an unnecessary alarm sound is output.

Therefore, in the technique described in Patent Document 1, the amount of time (continuous time) in which the measured value of the biological parameter (biological information) deviates from a predetermined range (setting range) so that an unnecessary alarm sound is not output. Outputs an alarm sound when the specified level (set time) is exceeded.

Japanese Patent No. 4553337

As described above, when there is a risk to the patient's living body, the alarm sound is output to call the staff (nurse, caregiving staff, etc.) from the nurse station or the like. In this case, when the staff goes near the patient, the staff gives an instruction (operation) to stop the output of the alarm sound and responds to the patient.

However, in the technique described in Patent Document 1, an alarm sound is output every time the continuous time when the measured value of the biological information deviates from the set range exceeds the set time. In this case, since the alarm sound is annoying when the staff is dealing with the patient, it is necessary to give an instruction (operation) to stop the output of the alarm sound. This is because, despite the fact that the staff is dealing with the patient, it is necessary to perform the above operation every time an alarm sound is output, and not only the alarm sound but also the above operation is troublesome.

However, even though the alarm sound is annoying, if the measured value deviates from the set range when the staff is dealing with the patient, the risk to the patient's body has not been solved yet. It is a fact.

In view of the above-mentioned problems, an object of the present invention is to notify a staff member when there is a risk to the patient's body and to notify the patient when the staff member is dealing with the patient. It is to provide a notification system capable of performing notification for the staff to recognize that the risk to the living body has not been solved yet.

The notification system of the present invention is a notification system that monitors and notifies the first condition in which the state of the person being assisted is set in the alarm monitoring state, and the state of the person being assisted deviates from the first condition. An alarm is output in the alarm notification state, and the first notification unit mounted on the first device and the first information are displayed when the alarm is output, and the second device is different from the first device. When the caregiver instructs the first device to stop the alarm in the alarm notification state in which the second notification unit mounted on the device is provided and the alarm and the first information are output, the first device is provided. The notification unit stops the output of the alarm, and the second notification unit continues to display the first information.

According to the present invention, a notification (alarm, first alarm display information) for calling a staff member when there is a risk to the patient's living body and a notification to the patient's living body when the staff is responding to the patient. Notification (first alarm display information) for making the staff aware that the risk of the above has not been solved yet can be performed.

[3. Screen (state) transition diagram]
FIG. 6 is a screen transition diagram (state transition diagram) showing a screen displayed on the display unit 170 of the display terminal 1000 of FIG.

First, when the system is started, it is determined whether or not the alarm is generated, that is, whether or not each measured value exceeds the alarm threshold value (or whether or not it is less than the alarm threshold value). Then, the alarm screen (P100) is displayed as needed. This alarm screen confirms that a problem has occurred, but the details of the error are not displayed until you log in. As a result, it is possible to prevent the patient P (FIG. 1) and the family from displaying the error content that should not be displayed.

The alarm screen is also displayed when the system is started, such as when the power is turned on, but it may be determined at any time whether or not the alarm is generated. Then, when an alarm occurs, the screen may be transitioned to the alarm screen as interrupt processing.

Subsequently, the patient status display screen (P102) is displayed as the main status. On this screen, the nameplate information, pictogram information, alert information, error status, etc. of patient P (FIG. 1) are displayed. This makes it possible to display necessary information for medical staff such as nurses and doctors, caregivers, and family members who are assisting.

The patient status display screen (P102) does not display detailed information because the patient P (FIG. 1), the family at the hospital, and other third parties who have visited the hospital can be seen. If necessary, the login screen (P104) is switched to by executing the authentication process and logging in. It is possible to transition to various screens from the login screen. For example, a biometric information display screen (P106) for displaying biometric information (each measured value), a graph display screen (P108) for displaying the transition of the measured value, and vital registration for registering the measured value in an electronic medical record. It is possible to switch to the screen (P110).

It is also possible to switch to the alarm setting / history screen (P116) for setting the conditions for the alarm occurrence status. On this alarm setting / history screen, not only the alarm threshold value can be set, but also other alert information and what to do next (for example, dosing instruction, etc.) can be operated.

In this way, according to the patient status display system 1 (FIG. 1), it is possible to centrally display the information related to the patient P (FIG. 1), and by switching the screen as necessary, appropriate information can be displayed. It becomes possible to display. In addition, by centrally acquiring information on a plurality of measuring devices and registering them in an electronic medical record, it is possible to centrally manage information on patient P (FIG. 1).

[4. Process flow]
Next, a processing flow in the display terminal 1000 (FIG. 3) of the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) will be described.

[4.1 Main processing]
FIG. 7 is a flowchart showing the operation (main processing) of the display terminal 1000 of FIG. The main process is a process realized by the control unit 100 of the display terminal 1000 of FIG. 3 reading and executing the main program 132 stored in the storage unit 110.

First, it is determined whether or not the alarm is generated (step S102). Specifically, it is determined whether or not the various measured values deviate from a predetermined range (whether or not the various measured values exceed the upper limit alarm threshold value and whether or not the various measured values are less than the lower limit alarm threshold value). Will be done. When various measured values deviate from a predetermined range (when various measured values exceed the upper limit alarm threshold value or when various measured values are less than the lower limit alarm threshold value), an alarm is generated and an alarm sounds. There is a need. Then, when it is necessary to output an alarm sound, the alarm process is executed (step S102; Yes → step S104). Here, in the alarm processing, the alarm screen may be displayed on the display unit 170 (FIG. 3) as the interrupt processing.

Regarding whether or not the various measured values deviate from the predetermined range (whether or not the various measured values exceed the upper limit alarm threshold value and whether or not the various measured values are less than the lower limit alarm threshold value), biometric information. It depends on the type of. Further, when the judgment criterion is not a predetermined range but only one alarm threshold value (that is, whether or not the measured value exceeds the upper limit alarm threshold value is judged, or the measured value is less than the lower limit alarm threshold value. In some cases, it is only determined whether or not it is.

Subsequently, the patient status display process is executed (step S106). In the patient state display process, the patient state display screen (P102) (FIG. 6) is displayed on the display unit 170 (FIG. 3). Here, if login authentication is not performed (or if login has failed), the process is repeatedly executed from step S102 (step S108; No → step S102).

If the login authentication is correctly performed (step S108; Yes), the login screen (P104) (FIG. 6) is displayed on the display unit 170 (FIG. 3) (step S110). That is, the screen displayed on the display unit 170 (FIG. 3) is switched from the patient status display screen (P102) to the login screen (P104). The login screen (P104) is a screen on which the staff can select various processes.

Here, when "biological information display" is selected as the staff process, the biometric information display process is executed (step S112; biometric information display → step S116). In the biological information display process, the biological information display screen (P106) (FIG. 6) is displayed on the display unit 170 (FIG. 3).

When "setting" is selected, the setting process is executed (step S112; setting → step S118). In the setting process, the alarm setting / history screen (P116) (FIG. 6) is displayed on the display unit 170 (FIG. 3). The setting process includes setting the alarm threshold value, registering / updating patient information, and the like.

Here, if logout is not executed, the login state continues (step S114; No → step S110), if logout is executed, logout is performed, and processing is repeatedly executed from step S102 (step S114; No → step). S102).

[4.2 Setting process]
In the setting process, the condition from the alarm monitoring state (described later) to the alarm notification state (described later), the notification method, and the condition to the alarm monitoring state are set according to the type of biological information 112, the type of measurement, and the item. And are set. FIG. 8 is a diagram for explaining the setting process of FIG. 7.

First, a case where the biological information 112 is continuous biological information 114, the measurement is “measurement”, and the item is “breathing” will be described. The condition from the alarm monitoring state (for example, see step S202 of FIGS. 9 and 10) to the alarm notification state (for example, see step S206 of FIGS. 9 and 10) is the continuous time during which the measured value deviates from the set range. (Continuous time in which the measured value exceeds the upper limit alarm threshold, continuous time in which the measured value is less than the lower limit alarm threshold) (see, for example, the continuous time T1 in FIG. 10) is the first set time (for example, in FIG. 10). When it is equal to or longer than the first set time Tth1), as a notification method at this time, an alarm sound output (for example, refer to the alarm sound AL in FIG. 10) and a warning display process (for example, a warning display in FIG. 10) are performed. Information W1 (blinking), warning display information W2 (lighting)) is executed. The conditions for the alarm monitoring state are the continuous time in which each measured value is within the set range after the alarm response is completed (the continuous time when the measured value is equal to or less than the upper limit alarm threshold value, and the continuous time when the measured value exceeds the lower limit alarm threshold value). Time) (see, for example, the continuous time T2 in FIG. 10) is greater than or equal to the second set time (see, for example, the second set time Tth2 in FIG. 10).

Next, a case where the biological information 112 is continuous biological information 114, the measurement is “measurement”, and the item is “pulse” will be described. The condition from the alarm monitoring state (for example, see step S202 of FIGS. 9 and 10) to the alarm notification state (for example, see step S206 of FIGS. 9 and 10) is the continuous time during which the measured value deviates from the set range. (Continuous time in which the measured value exceeds the upper limit alarm threshold, continuous time in which the measured value is less than the lower limit alarm threshold) (see, for example, the continuous time T1 in FIG. 10) is the first set time (for example, in FIG. 10). When it is equal to or longer than the first set time Tth1), as a notification method at this time, an alarm sound output (for example, refer to the alarm sound AL in FIG. 10) and a warning display process (for example, a warning display in FIG. 10) are performed. Information W1 (blinking), warning display information W2 (lighting)) is executed. The conditions for the alarm monitoring state are the continuous time in which each measured value is within the set range after the alarm response is completed (the continuous time when the measured value is equal to or less than the upper limit alarm threshold value, and the continuous time when the measured value exceeds the lower limit alarm threshold value). Time) (see, for example, the continuous time T2 in FIG. 10) is greater than or equal to the second set time (see, for example, the second set time Tth2 in FIG. 10). Here, the set range (upper limit alarm threshold value, lower limit alarm threshold value), first set time, second set time, and the like are different from those in the case of "breathing".

Next, a case where the biological information 112 is continuous biological information 114, the measurement is the “bed determination” by the determination of the bed 3 (FIG. 1), and the item is “getting out of bed” will be described. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) determines that the bed has left the bed in the alarm setting state of getting out of bed. As a notification method at this time, an alarm sound output and a warning display process (for example, Warning display information (blinking)) is executed. Further, the condition for the alarm monitoring state is the case where the bed 3 (FIG. 1) is determined to be in bed from the determination of getting out of bed.

Next, a case where the biological information 112 is continuous biological information 114, the measurement is the “bed determination” by the determination of the bed 3 (FIG. 1), and the item is the “end sitting position” will be described. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) determines the end sitting position in the end sitting position alarm setting state, and as a notification method at this time, an alarm sound output and a warning display process ( For example, warning display information (blinking)) is executed. Further, the condition for the alarm monitoring state is the case where the bed 3 (FIG. 1) is determined to be in bed from the end sitting position determination.

Next, a case where the biological information 112 is continuous biological information 114, the measurement is the “bed determination” by the determination of the bed 3 (FIG. 1), and the item is “get up” will be described. The condition from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) is determined to rise in the alarm setting state of rising, and as a notification method at this time, alarm sound output and warning display processing (for example, warning display processing) Warning display information (blinking)) is executed. Further, the condition for the alarm monitoring state is the case where the bed 3 (FIG. 1) is determined to lie down from the determination of getting up.

Next, the biological information 112 is the measured biological information 116, the measurement is "measurement", and the items are "blood pressure", "SpO2 (percutaneous arterial oxygen saturation)", "blood glucose", and "body temperature". The case will be described. The condition from the alarm monitoring state to the alarm notification state is that when the staff measures patient P (Fig. 1) during the round, various measured values deviate from the set range, and as a notification method at this time, Warning display processing is executed. At this time, the staff stops the execution of the warning display process, so the condition for the alarm monitoring state is not set.

FIG. 9 is a diagram for explaining a state set by the setting process, and is a flowchart showing the alarm process of FIG. 7. As shown in FIG. 9, in the setting process, as a procedure for executing the alarm process, when an alarm status occurs in "alarm monitoring", the setting process shifts to "alarm occurring" and the alarm status is canceled. Return to "Alarm monitoring". In addition, when the staff gives an alarm monitoring stop instruction in "alarm monitoring", it becomes "alarm monitoring stop". In "Alarm monitoring in progress", the alarm monitoring state (step S202) described later is set. In "Alarm is occurring", the alarm notification state (step S206), the alarm response state (step S208), and the alarm observation state (step S212), which will be described later, are set. In the "alarm monitoring stop", since the staff has given an alarm monitoring stop instruction, the alarm monitoring state (step S202) described later does not occur.

The alarm processing needs to be performed based on the measured value (measured value) even when the staff is not near the patient P (FIG. 1). Therefore, as an alarm process, FIG. 9 shows a case where the biological information 112 (FIG. 8) is continuous biological information 114 (FIG. 8), the measurement is “measurement”, and the item is “breathing” or “pulse”. It will be described using. The alarm process is a process executed in step S104 of FIG. 7, and is realized by the control unit 100 of the display terminal 1000 of FIG. 3 reading and executing the alarm program 134 stored in the storage unit 110. Is.

First, in the alarm monitoring state (step S202), the control unit 100 (FIG. 3) determines whether or not the measured value of “breathing” or “pulse” deviates from the set range (the measured value exceeds the upper limit alarm threshold value). Whether or not the measured value is below the lower limit alarm threshold value) is monitored.

Now, in the alarm monitoring state (step S202), the measured value of "breathing" or "pulse" does not deviate from the set range (the measured value does not exceed the upper limit alarm threshold value, or the measured value is less than the lower limit alarm threshold value. is not it). In this case, since the alarm status has not occurred (step S204-No), the control unit 100 (FIG. 3) executes step S202.

Now, in the alarm monitoring state (step S202), the measured value of "breathing" or "pulse" deviates from the set range (the measured value exceeds the upper limit alarm threshold value, or the measured value is less than the lower limit alarm threshold value. Is). In this case, the control unit 100 (FIG. 3) needs to monitor whether or not an alarm status occurs. Therefore, if the continuous time in which the measured value of "breathing" or "pulse" deviates from the set range is equal to or longer than the first set time, an alarm status has occurred (step S204-Yes), so alarm processing. Shifts from the alarm monitoring state (step S202) to the alarm notification state (step S206).

In the alarm notification state (step S206), the control unit 100 of FIG. 3 controls the sound notification unit 262 of the notification unit 260 of the connection device 2000 so as to output the alarm sound, and outputs the first alarm display information. As described above, the optical notification unit 264 of the notification unit 260 of the connection device 2000 is controlled. Here, the sound notification unit 262 of FIG. 3 may be on the display terminal 1000. Further, when the alarm program 134 of FIG. 3 is in the connecting device 2000, the control unit 200 may control the sound notification unit 262.

In the alarm notification state (step S206), when the staff instructs the display terminal 1000 (or the connection device 2000) of the patient status display device 10 of FIG. 2 to stop the alarm, the control unit 100 (FIG. 3) , The sound notification unit 262 (FIG. 3) is controlled so as to stop the output of the alarm sound. The alarm processing shifts from the alarm notification state (step S206) to the alarm response state (step S208). Here, in the alarm notification state (step S206), the alarm notification is also notified to the terminal device 50 (FIG. 1) and the mobile terminal device 55 (FIG. 1), and the alarm sound is emitted to the terminal device 50 and the mobile terminal device 55. Generate a vibe. Even when the terminal device 50 or the mobile terminal device 55 instructs to stop the alarm, the control unit 100 may control the sound notification unit 262 so as to stop the output of the alarm sound.

In the alarm response state (step S208), the staff is responding to patient P (FIG. 1). In this case, the optical notification unit 264 (FIG. 3) continues to output the first alarm display information.

In the alarm response state (step S208), the staff responds to the patient P (FIG. 1) and performs an alarm response completion operation on the display terminal 1000 (or the connection device 2000) of the patient status display device 10 of FIG. If so, the alarm response state (step S208) is completed. That is, the alarm response is completed. When the measured value that deviated from the set range falls within the set range after the alarm response completion operation (the measured value that exceeded the upper limit alarm threshold does not exceed the upper limit alarm threshold value, or is less than the lower limit alarm threshold value. When the measured value was not less than the lower limit alarm threshold value), the alarm status was resolved (step S210-Yes). In this case, the alarm processing shifts from the alarm response state (step S208) to the alarm monitoring state (step S202).

On the other hand, in the alarm response state (step S208), the staff responds to the patient P (FIG. 1) and completes the alarm response to the display terminal 1000 (or the connection device 2000) of the patient status display device 10 of FIG. The operation was performed, but the measured value of "breathing" or "pulse" is still out of the set range (the measured value exceeds the upper limit alarm threshold value, or the measured value is less than the lower limit alarm threshold value). .. In this case, since the alarm status has not been resolved (step S210-No), the control unit 100 (FIG. 3) needs to observe whether or not the alarm status occurs again. Therefore, the alarm processing shifts to the alarm observation state after the alarm response completion operation in the alarm response state (step S208) (step S212).

In the alarm observation state (step S212), when the measured value deviating from the set range becomes within the set range (when the measured value exceeding the upper limit alarm threshold value does not exceed the upper limit alarm threshold value, or the lower limit alarm When the measured value that was less than the threshold value is not less than the lower limit alarm threshold value), the control unit 100 (FIG. 3) needs to further monitor whether or not an alarm situation occurs. Therefore, the control unit 100 (FIG. 3) controls the optical notification unit 264 (FIG. 3) so as to output the second alarm display information different from the first alarm display information.

Now, in the alarm observation state (step S212), if the continuous time in which the measured values of "breathing" or "pulse" do not deviate from the set range is equal to or longer than the second set time, the alarm status has not occurred. (Step S214-Yes), the control unit 100 (FIG. 3) controls the optical notification unit 264 (FIG. 3) so as to stop the output of the second alarm display information. The alarm processing shifts from the alarm observation state (step S212) to the alarm monitoring state (step S202).

On the other hand, in the alarm observation state (step S212), if the continuous time in which the measured values of "breathing" or "pulse" do not deviate from the set range is less than the second set time, the alarm situation may occur again. There is (step S214-No).

Here, when the time after the alarm response completion operation does not elapse the third set time longer than the second set time, that is, when the time is not over (step S216-No), the control unit 100 (step S216-No) FIG. 3) executes step S212.

Alternatively, when the alarm processing does not shift from the alarm observation state (step S212) to the alarm monitoring state (step S202) even after the third set time has elapsed after the alarm response completion operation, that is, When the time is over (step S216-Yes), the alarm processing shifts from the alarm observation state (step S212) to the alarm notification state (step S206).

[5. Operation example]
Subsequently, as an operation example of this embodiment, an example will be described. FIG. 10 is a timing chart for explaining an example of the alarm processing of FIG.

First, whether or not the measured value V of "breathing" or "pulse" deviates from the set range Rth (whether or not the measured value V exceeds the upper limit alarm threshold value Vth1 and the measured value V is less than the lower limit alarm threshold value Vth2). Whether or not there is) is monitored (step S202: alarm monitoring state).

Now, at time t1, the measured value V of "breathing" or "pulse" deviates from the set range Rth. For example, the measured value V exceeds the upper limit alarm threshold value Vth1. Further, at time t2 after time t1, the continuous time T1 in which the measured value V of “breathing” or “pulse” deviates from the set range Rth is equal to or greater than the first set time Tth1 as the above-mentioned first set time. If (T1 ≧ Tth1), an alarm status has occurred (step S204-Yes).

At time t2, the sound notification unit 262 outputs an alarm sound AL. The optical notification unit 264 outputs the first alarm display information W1. For example, the light notification unit 264 is a light emitting element such as an LED (Light Emitting Diode), and the LED is blinking and displayed as the first alarm display information W1 (step S206: alarm notification state).

When the staff instructs the alarm to stop at the time t3 after the time t2, the sound notification unit 262 stops the output of the alarm sound. In this case, the optical notification unit 264 continues to output the first alarm display information W1. That is, the optical notification unit 264 is blinking. At this time, the staff responds to the patient P (FIG. 1) (step S208: alarm response state).

At time t4 after time t3, staff responds to patient P (FIG. 1). Here, the staff corresponds to the patient P (FIG. 1) and performs an operation of completing the alarm response to the display terminal 1000 (or the connecting device 2000) of the patient status display device 10 of FIG. In this case, the optical notification unit 264 outputs the second alarm display information W2 different from the first alarm display information W1 (blinking display). For example, when the light notification unit 264 is a light emitting element such as an LED, the LED is lit and displayed as the second alarm display information W2 instead of blinking (step S212: alarm observation state).

At time t5 after time t4, the measured value V that deviated from the set range Rth became within the set range Rth (the measured value V that exceeded the upper limit alarm threshold Vth1 did not exceed the upper limit alarm threshold Vth1). .. Even in this case, the optical notification unit 264 continues to output the second alarm display information W2. That is, the optical notification unit 264 is lit and displayed.

At time t6 after time t5, the continuous time T2 in which the measured value V of “breathing” or “pulse” does not deviate from the set range Rth is the second set time Tth2 or more as the second set time (T2). ≤Tth2). In this case, since the alarm status has not occurred (step S214-Yes), the optical notification unit 264 stops the lighting display by stopping the output of the second alarm display information W2 (step S202: alarm monitoring). Status).

At time t7 after time t6, the measured value V of “breathing” or “pulse” deviates from the set range Rth. For example, the measured value V exceeds the upper limit alarm threshold value Vth1. Further, at time t8 after time t7, when the continuous time T3 in which the measured value V of “breathing” or “pulse” deviates from the set range Rth is equal to or greater than the first set time Tth1 (T3 ≧ Tth1). ), An alarm status has occurred (step S204-Yes).

At time t8, the sound notification unit 262 outputs an alarm sound AL. The optical notification unit 264 blinks and displays by outputting the first alarm display information W1 (step S206: alarm notification state). As described above, when the staff instructs to stop the alarm, the alarm notification state is changed to the alarm response state.

Based on the above description, the notification device of the present invention uses the patient status display device 10 (FIGS. 1 and 2) of the patient status display system 1 (FIG. 1) to perform alarm processing as described above (steps S104 and FIG. 9 of FIG. 7). , FIG. 10) is realized. In order to realize the alarm processing, in the notification device (patient status display device 10) of the present invention, the measured value V (FIG. 10) is set in the set range Rth (FIG. 10) in the alarm monitoring state (step S202 of FIGS. 9 and 10). The control unit 100 (FIG. 3) that monitors whether or not the measurement value deviates from 10) and the continuous time T1 (FIG. 10) in which the measured value V deviates from the set range Rth are the first set time Tth1 (FIG. 10). ) Or more (steps S204-Yes in FIGS. 9 and 10), when the sound notification unit 262 (FIGS. 3 and 10) that outputs the alarm sound AL (FIG. 10) and the alarm sound AL are output, the first It is provided with an optical notification unit 264 (FIGS. 3 and 10) that outputs the alarm display information W1 (FIG. 10) of 1. When the staff instructs to stop the alarm in the alarm notification state (step S206 in FIGS. 9 and 10) in which the alarm sound AL and the first alarm display information W1 are output, the sound notification unit 262 outputs the alarm sound AL. To stop. After the alarm response completion operation, the optical notification unit 264 outputs the second alarm display information W2 (FIG. 10) different from the first alarm display information W1.

In order to realize the alarm processing, it is set in the alarm observation state (S210-No, S212 in FIGS. 9 and 10) in which the output of the first alarm display information W1 (FIG. 10) is continuing after the alarm response completion operation. Even when the measured value V (FIG. 10) deviating from the range Rth (FIG. 10) falls within the set range Rth, the optical notification unit 264 (FIGS. 3 and 10) outputs the second alarm display information W2. To continue.

In order to realize the alarm processing, in the alarm observation state (S212 of FIGS. 9 and 10), the continuous time T2 (FIG. 10) in which the measured value V (FIG. 10) does not deviate from the set range Rth (FIG. 10) is set. When the second set time Tth2 (FIG. 10) or more (S214-Yes in FIGS. 9 and 10), the optical notification unit 264 (FIGS. 3 and 10) stops the output of the second alarm display information W2. In the alarm monitoring state (S202 of FIGS. 9 and 10) after the output of the second alarm display information W2 is stopped, the control unit 100 (FIG. 3) monitors whether or not the measured value V deviates from the set range Rth. do.
