Description

The present invention relates to a notification system.

Conventionally, there is a known technology that acquires biometric information from a patient in a hospital bed and outputs an alarm sound when the measured value of the biometric information deviates from a set range because there is a risk to the patient's body. . The alarm sound is output from a nurse station or the like to call staff (nurses, care staff, etc.).

However, there are cases where the measured value of the acquired biological information sharply increases (or decreases sharply) 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) during which the measured value of the biological parameter (biological information) deviates from a predetermined range (set range) so as not to output an unnecessary alarm sound. An alarm sound is output when the time exceeds a predetermined level (set time).

Japanese Patent No. 4553337

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

However, in the technique described in Patent Literature 1, an alarm sound is output each time the continuous time during which the measured value of biological information is out of the set range exceeds the set time. In this case, since the alarm sound is annoying while 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 the above operation must be performed every time an alarm sound is output even though the staff is treating the patient, and the above operation as well as the alarm sound is troublesome.

However, even if the alarm sound is bothersome, if the measured value deviates from the set range while the staff is responding to the patient, it means that the risk to the patient's body has not yet been resolved. It is a fact.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the object of the present invention is to provide a notification for calling staff when there is a risk to the patient's body, and a patient's response when the staff is dealing with the patient. To provide a notification system capable of performing notification for making staff aware that a risk to a living body has not yet been resolved.

A notification system according to the present invention is a notification system that monitors and notifies a first condition in which the condition of a person being assisted is set in an alarm monitoring state, wherein the condition of the person being assisted deviates from the first condition. a first notification unit mounted in a first device, and a second notification unit that displays first information when the alarm is output and a second device that is different from the first device a second notification unit mounted on a device, wherein in the alarm notification state in which the alarm and the first information are output, when an assistant instructs the first device to stop the alarm, the first The notification unit stops outputting 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 the staff when there is a risk to the patient's body, and (first warning display information) for making the staff aware that the risk of the problem has not yet been resolved.

The optical notification unit 264 is normally invisible, and may be configured to display by lighting or blinking only when the notification is given.

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

First, when the system is activated, it is determined whether or not an alarm has occurred, that is, whether or not each measured value exceeds an alarm threshold (or whether or not it is less than an alarm threshold). Then, an alarm screen (P100) is displayed as necessary. On this alarm screen, you can confirm that a problem has occurred, but the content of the error is not displayed until you log in. As a result, the error content that should not be displayed to the patient P (FIG. 1) and family members can be prevented from being displayed.

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

Subsequently, the patient condition display screen (P102) is displayed as the main condition. On this screen, the nameplate information, pictogram information, alert information, error state, etc. of the patient P (FIG. 1) are displayed. As a result, necessary information can be displayed for medical personnel such as nurses and doctors, caregivers, and family members providing care.

The patient status display screen (P102) does not display detailed information because the patient P (FIG. 1), family members at the hospital, and third parties who visit the patient can see the patient. If necessary, the authentication process is executed and the login screen is displayed (P104). From the login screen, it is possible to transition to various screens. For example, a biological information display screen (P106) that displays biological information (each measured value), a graph display screen (P108) that can display the transition of the measured value, and a vital registration that registers the measured value in an electronic medical record It is possible to switch to the screen (P110).

It is also possible to switch to an alarm setting/history screen (P116) for setting the conditions for alarm occurrence. On this alarm setting/history screen, it is possible not only to set the alarm threshold value, but also to operate other alert information and what to do next (for example, instructions for medication, etc.).

Thus, according to the patient condition display system 1 (FIG. 1), it is possible to centrally display information about the patient P (FIG. 1), and by switching screens as necessary, appropriate information can be displayed. can be displayed. In addition, by centrally acquiring information on a plurality of measuring devices and registering it in an electronic medical record, it is possible to centrally manage information on the patient P (FIG. 1).

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

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

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

Regarding whether or not the various measurement values deviate from the predetermined range (whether or not the various measurement values exceed the upper limit alarm threshold, whether or not the various measurement values are less than the lower limit alarm threshold), biological information depends on the type of In addition, when the determination criterion is not a predetermined range but only one alarm threshold value (that is, when determining only whether the measured value exceeds the upper limit alarm threshold value, or when the measured value is less than the lower limit alarm threshold value There is also a case where only determination is made as to whether or not

Subsequently, patient condition display processing is executed (step S106). In the patient condition display process, the patient condition display screen (P102) (FIG. 6) is displayed on the display unit 170 (FIG. 3). Here, if the login authentication is not performed (or if the login fails), 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) switches from the patient condition 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 staff processing, biological information display processing is executed (step S112; biological information display→step S116). In the biometric information display process, the biometric information display screen (P106) (FIG. 6) is displayed on the display unit 170 (FIG. 3).

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

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

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

First, a case where the biological information 112 is the continuous biological information 114, the measurement is "measurement", and the item is "respiration" will be described. The condition from the alarm monitoring state (for example, see step S202 in FIGS. 9 and 10) to the alarm notification state (for example, see step S206 in FIGS. 9 and 10) is that the measured value is out of the set range for a continuous period of time. (The continuous time during which the measured value exceeds the upper limit alarm threshold, the continuous time during 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. (see first set time Tth1) or more, and as a notification method at this time, alarm sound output (for example, see alarm sound AL in FIG. 10), warning display processing (for example, warning display in FIG. 10) information W1 (blinking) and warning display information W2 (lighting)) is executed. In addition, the conditions for the alarm monitoring state are the continuous time that each measured value is within the set range after the completion of the alarm response (continuous time that the measured value is below the upper limit alarm threshold, and continuous time that the measured value is above the lower limit alarm threshold). 10) is equal to or longer than the second set time (see, for example, the second set time Tth2 in FIG. 10).

Next, a case where the biological information 112 is the 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 in FIGS. 9 and 10) to the alarm notification state (for example, see step S206 in FIGS. 9 and 10) is that the measured value is out of the set range for a continuous period of time. (The continuous time during which the measured value exceeds the upper limit alarm threshold, the continuous time during 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. (see first set time Tth1) or more, and as a notification method at this time, alarm sound output (for example, see alarm sound AL in FIG. 10), warning display processing (for example, warning display in FIG. 10) information W1 (blinking) and warning display information W2 (lighting)) is executed. In addition, the conditions for the alarm monitoring state are the continuous time that each measured value is within the set range after the completion of the alarm response (continuous time that the measured value is below the upper limit alarm threshold, and continuous time that the measured value is above the lower limit alarm threshold). 10) is equal to or longer than the second set time (see, for example, the second set time Tth2 in FIG. 10). Here, the setting range (upper limit alarm threshold, lower limit alarm threshold), first set time, second set time, etc. are different from those for "breathing".

Next, a case will be described where the biological information 112 is the continuous biological information 114, the measurement is "bed determination" based on the determination of the bed 3 (FIG. 1), and the item is "getting out of bed". The condition for transitioning from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) determines that the bed 3 (FIG. 1) has left the bed while the alarm is set to leave the bed. Warning display information (flashing)) is executed. Further, the condition for entering the alarm monitoring state is when the bed 3 (FIG. 1) is determined to be in bed from being determined to be out of bed.

Next, a case will be described where the biological information 112 is the continuous biological information 114, the measurement is "bed determination" based on the determination of the bed 3 (FIG. 1), and the item is "edge sitting". The condition for transitioning from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) is determined to be in the edge sitting position in the alarm setting state of the edge sitting position. For example, warning display information (flashing) is executed. Further, the condition for the alarm monitoring state is when the bed 3 (FIG. 1) is determined to be in bed from the edge sitting position determination.

Next, a case will be described where the biological information 112 is the continuous biological information 114, the measurement is "bed determination" based on the determination of the bed 3 (FIG. 1), and the item is "getting up". The condition for shifting from the alarm monitoring state to the alarm notification state is when the bed 3 (FIG. 1) determines that the bed 3 (FIG. 1) has risen in the wake-up alarm setting state. Warning display information (flashing)) is executed. Further, the condition for entering the alarm monitoring state is when the bed 3 (FIG. 1) is determined to be lying down from being determined to be 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 blood oxygen saturation)", "blood sugar", and "body temperature". A case will be described. The condition for changing from the alarm monitoring state to the alarm notification state is that when the staff measures the patient P (FIG. 1) during the round, various measured values deviate from the set range. A warning display process is executed. At this time, since the staff stops the execution of the warning display process, the conditions for the alarm monitoring state are not set.

FIG. 9 is a diagram for explaining the states set in the setting process, and is a flowchart showing the alarm process of FIG. As shown in FIG. 9, in the setting process, as a procedure for executing the alarm process, when an alarm condition occurs in "alarm monitoring", the transition to "alarm occurring" occurs, and when the alarm condition is canceled to return to "alarm monitoring". Also, when the staff issues an instruction to stop alarm monitoring during "alarm monitoring", "alarm monitoring is stopped". In "alarm monitoring", an alarm monitoring state (step S202), which will be described later, is entered. In the "alarm occurring" state, an alarm notification state (step S206), an alarm response state (step S208), and an alarm observation state (step S212) are set. In the case of "alarm monitoring stop", the staff does not enter the alarm monitoring state (step S202), which will be described later, since the staff has issued an alarm monitoring stop instruction.

[4.3 Alarm processing]
Alarm processing must be performed based on measured values (measured values) even when the staff is not near the patient P (FIG. 1). Therefore, as alarm processing, FIG. will be used for explanation. The alarm process is a process executed in step S104 of FIG. 7, and is realized by reading and executing the alarm program 134 stored in the storage unit 110 by the control unit 100 of the display terminal 1000 of FIG. is.

First, in the alarm monitoring state (step S202), the control unit 100 (FIG. 3) determines whether the measured value of "breathing" or "pulse" deviates from the set range (the measured value exceeds the upper limit alarm threshold). and whether the measured value is less than the lower alarm threshold).

Now, in the alarm monitoring state (step S202), the measured value of "respiration" or "pulse" does not deviate from the set range (the measured value does not exceed the upper limit alarm threshold, or the measured value is less than the lower limit alarm threshold). is not). In this case, since no alarm condition has 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 "respiration" or "pulse" deviates from the set range (the measured value exceeds the upper limit alarm threshold or the measured value is less than the lower limit alarm threshold). is). In this case, the controller 100 (FIG. 3) needs to monitor whether an alarm condition occurs. Therefore, if the continuous time during which the measured value of "respiration" or "pulse" deviates from the set range is equal to or longer than the first set time, it means that an alarm condition has occurred (step S204-Yes), and alarm processing is performed. moves 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 an alarm sound, and outputs the first alarm display information. Thus, the optical notification unit 264 of the notification unit 260 of the connection device 2000 is controlled. Here, the sound notification unit 262 in FIG. 3 may be provided in the display terminal 1000 . Moreover, when the alarm program 134 of FIG.

In the alarm notification state (step S206), when the staff instructs the display terminal 1000 (or connection device 2000) of the patient condition display device 10 of FIG. 2 to stop the alarm, the control unit 100 (FIG. 3) , controls the sound notification unit 262 (FIG. 3) to stop outputting the alarm sound. The alarm process shifts from the alarm notification state (step S206) to the alarm response state (step S208). Here, in the alarm notification state (step S206), the terminal device 50 (FIG. 1) and the mobile terminal device 55 (FIG. 1) are also notified of the alarm notification, and the terminal device 50 and the mobile terminal device 55 receive an alarm sound, generate a vibration. 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 to stop outputting the alarm sound.

In the alarm response state (step S208), the staff is responding to the 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 operates the display terminal 1000 (or the connection device 2000) of the patient condition display device 10 in FIG. 2 to complete the alarm response. If so, the alarm response state (step S208) is completed. That is, the alarm response is completed. When the measured value that deviates from the set range becomes within the set range after the alarm response completion operation (when the measured value exceeding the upper limit alarm threshold does not exceed the upper limit alarm threshold, or when it is less than the lower limit alarm threshold) If the measured value found is not less than the lower alarm threshold), the alarm condition has been 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 sends an alarm response completion message to the display terminal 1000 (or connection device 2000) of the patient condition display device 10 in FIG. Operation has been performed, but the "Respiration" or "Pulse" measurement value is still outside the set range (the measurement value exceeds the upper alarm threshold or the measurement value is below the lower alarm threshold) . In this case, since the alarm condition has not been resolved (step S210-No), the control unit 100 (FIG. 3) needs to observe whether the alarm condition occurs again. Therefore, the alarm process shifts to the alarm observation state (step S212) after the alarm response completion operation in the alarm response state (step S208).

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

Now, in the alarm observation state (step S212), if the continuous time during which the measured value of "respiration" or "pulse" does not deviate from the set range is equal to or longer than the second set time, it means that no alarm has occurred. (Step S214-Yes), the control unit 100 (FIG. 3) controls the optical notification unit 264 (FIG. 3) to stop outputting the second alarm display information. The alarm process shifts from the alarm observing 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 during which the measured value of "respiration" or "pulse" does not deviate from the set range is less than the second set time, there is a possibility that the alarm situation will occur again. (step S214-No).

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

Alternatively, if the alarm processing has not transitioned from the alarm observation state (step S212) to the alarm observation state (step S202) even after the third set time has passed since the alarm response completion operation, that is, If the time is over (step S216-Yes), the alarm process shifts from the alarm observation state (step S212) to the alarm notification state (step S206).

[5. Operation example]
Next, an example will be described as an operation example of the present embodiment. FIG. 10 is a timing chart for explaining an example of alarm processing in 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 whether the measured value V is less than the lower limit alarm threshold value Vth2). presence or absence) is monitored (step S202: alarm monitoring state).

Now, at time t1, the measured value V of "respiration" or "pulse" deviates from the set range Rth. For example, the measured value V exceeds the upper limit alarm threshold value Vth1. Furthermore, at time t2 after time t1, the continuous time T1 during which the measured value V of "breathing" or "pulse" deviates from the set range Rth is equal to or longer than the first set time Tth1 as the first set time described above. (T1≧Tth1), an alarm condition has occurred (step S204—Yes).

At time t2, sound notification unit 262 outputs alarm sound AL. The optical notification unit 264 outputs 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 blinks as the first alarm display information W1 (step S206: alarm notification state).

At time t3 after time t2, when the staff instructs to stop the alarm, the sound notification unit 262 stops outputting the alarm sound. In this case, the optical notification unit 264 continues to output the first alarm display information W1. That is, the light 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, the staff attends to patient P (FIG. 1). Here, the staff responds to the patient P (FIG. 1) and operates the display terminal 1000 (or the connection device 2000) of the patient condition display device 10 of FIG. 2 to complete the alarm response. In this case, the optical notification unit 264 outputs the second alarm display information W2 different from the first alarm display information W1 (flashing display). For example, if the light notification unit 264 is a light-emitting element such as an LED, the second alarm display information W2 is displayed by lighting the LED instead of blinking (step S212: alarm observation state).

At time t5 after time t4, the measured value V that had deviated from the set range Rth became within the set range Rth (the measured value V that had 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. In other words, the light notification unit 264 is illuminated.

At time t6 after time t5, the continuous time T2 during which the measured value V of "respiration" or "pulse" does not deviate from the set range Rth is equal to or longer than the second set time Tth2 as the second set time (T2 ≤ Tth2). In this case, since an alarm condition 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 State).

At time t7 after time t6, the measured value V of "respiration" or "pulse" deviates from the set range Rth. For example, the measured value V exceeds the upper limit alarm threshold value Vth1. Furthermore, at time t8 after time t7, if the continuous time T3 during which the measured value V of "breathing" or "pulse" deviates from the set range Rth is equal to or longer than the first set time Tth1 (T3≧Tth1 ), an alarm condition has occurred (step S204-Yes).

At time t8, sound notification unit 262 outputs alarm sound AL. The optical notification unit 264 blinks 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 shifted to the alarm response state.

In order to realize the alarm processing, the notification device (patient condition display device 10) of the present invention sets the measured value V (FIG. 10) to the set range Rth (FIG. 10) in the alarm monitoring state (step S202 in FIGS. 10), and the continuous time T1 (FIG. 10) during which the measured value V deviates from the set range Rth is the first set time Tth1 (FIG. 10). ) or more (step S204-Yes in FIGS. 9 and 10), the sound notification unit 262 (FIGS. 3 and 10) that outputs the alarm sound AL (FIG. 10), and when the alarm sound AL is output, the second and an optical notification unit 264 (FIGS. 3 and 10) for outputting one alarm display information W1 (FIG. 10). 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, when the staff instructs to stop the alarm, the sound notification unit 262 outputs the alarm sound AL. to stop. After the alarm handling 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 the alarm monitoring state (S202 in FIGS. 9 and 10) after the output of the second alarm display information W2 is stopped, the control unit 100 (FIG. 3) monitors whether the measured value V deviates from the set range Rth. do.
