Description
Technical Field
The invention relates to the medical field, in particular to patient monitoring equipment and an alarm method thereof.
Background
The patient monitoring device acquires the monitored data of various physiological parameters (such as electrocardio, blood oxygen, blood pressure and the like) of the patient, processes and analyzes the monitored data, and presents alarm information according to the comparison result of the analysis result and the alarm condition. Providing alarm information is one of the most important functions of patient monitoring devices, and can prompt medical care to pay attention to the patient and to intervene according to the alarm information.
Clinically, the monitored data of some physiological parameters may fluctuate just around the critical range corresponding to meeting the alarm condition in which the alarm occurs. For example, the heart rate of a patient fluctuates between 110 and 130, and the upper limit of the alarm threshold is 120 (the unit is bmp, i.e. times/minutes), when the heart rate of the patient is above 120, and the heart rate exceeds the upper limit 120 of the alarm threshold, the patient monitoring device outputs alarm information, and each time the monitoring device outputs alarm information, the medical care needs to manually click a specific function key on the screen of the monitoring device to confirm the alarm information, and the output of the alarm information can be stopped. When the heart rate of the patient falls back to 120 or below, the alarm condition is not met, the alarm information disappears, and the alarm information is frequently confirmed by medical staff in a short time after repeated operation, and the medical staff is easy to feel dislike or alarm fatigue after repeated operation.

As described above, when the monitored data of the physiological parameter fluctuates exactly at the attachment of the alarm condition, the patient monitoring device will alarm multiple times in a short time, causing alarm fatigue for the medical staff. For this disadvantage, there are the following strategies to reduce the number of alarms:
1. the mask period/refractory period strategy specifically causes the patient monitoring device to not alarm for a period of time after the alarm has occurred. The strategy can avoid frequent alarm of patient monitoring equipment, but in the shielding period/refractory period, no reminding about abnormal signs of the patient exists, and the risk of alarm omission exists;
2. alarm delay policies, specifically, include both an automatic delay entry alarm policy and an automatic delay exit alarm policy.
Wherein, the automatic delay entering alarm strategy is to reduce the alarm frequency by changing the alarm condition to reduce the transient alarm. However, the alarm condition of this strategy is difficult to determine, and there is an upper limit on performance: if the alarm condition is too high, the risk of missing an alarm exists; if the alarm condition is too low, the effect of reducing the alarm times is not obvious.
The automatic delay exit alarm strategy refers to connecting a plurality of alarms with short duration to an alarm with longer duration, thereby reducing the number of alarms, and the strategy does not affect the alarm condition or clinical risk. However, the strategy ignores the clinical actual use scene, and although the number of alarming times is reduced, the duration of alarming is increased, if alarming information exists all the time, the effect of reducing alarming fatigue cannot be produced, the method is also suitable, and the medical staff can be influenced to review the alarming trend of the patient after the fact, so that the diagnosis efficiency of the medical staff is reduced.
In view of the foregoing, an embodiment of the present invention provides a patient monitoring device, as shown in fig. 1, which includes a data acquisition module 110, an output device 120, and a controller 130.
Wherein, the data acquisition module 110 is configured to acquire monitored data of at least one physiological parameter of a patient; the output device 120 comprises at least a display for displaying the monitored data of the physiological parameter in the monitored interface; the controller 130 is configured to determine whether the monitored data of the currently monitored physiological parameter of the at least one item target meets a first alarm condition; when judging that the monitored data of the currently monitored physiological parameter of the at least one project label meets the first alarm condition, controlling the output device 120 to output first alarm information; acquiring alarm reset operation of a user in the process of outputting the first alarm information; in response to the alarm reset operation, the control output device 120 outputs second alarm information, wherein the first alarm information has a more prominent presentation manner than the second alarm information; judging whether the monitored data of the at least one currently monitored physiological parameter meets a first alarm condition or not and judging whether the monitored data of the at least one currently monitored physiological parameter meets a second alarm condition or not in the process of outputting the second alarm information; if the monitored data of the currently monitored physiological parameter of the at least one item target does not meet the first alarm condition but meets the second alarm condition, the control output device 120 outputs third alarm information, wherein the second alarm condition is easier to meet than the first alarm condition.
The patient monitoring device 100 of embodiments of the present invention includes, but is not limited to, any one of a monitor, a local central station, a remote central station, a cloud service system, a mobile terminal, or a combination thereof. The patient monitoring device 100 may be a portable monitoring device, a ambulatory monitoring device, a mobile monitoring device, or the like.
In one embodiment, the patient monitoring device 100 may be a monitor for real-time monitoring of monitored parameters of a patient, which may include bedside monitors, wearable monitors, etc., ventilator monitors, anesthesia monitors, defibrillation monitors, intracranial pressure monitors, electrocardiographic monitors, etc.
The monitoring device may also include a central station for receiving the monitoring data transmitted by the monitors and for centrally monitoring a plurality of patients. The central station may include a local central station or a remote central station, among others. The central station connects monitors in a department or a plurality of departments through a network so as to achieve the purposes of real-time centralized monitoring and mass data storage. For example, the central station stores monitoring data, basic information of a patient, medical history information, diagnostic information, and the like, but is not limited thereto.
In some embodiments, the monitor and the central station may form an interconnection platform through a BeneLink to enable data communication between the monitor and the central station, e.g., the central station may access the monitored data monitored by the monitor. In other embodiments, the monitor and the central station may also establish a data connection through a communication module including, but not limited to, a mobile communication module such as WiFI, bluetooth, NFC, zigBee, ultra wideband UWB, or 2G, 3G, 4G, 5G, or a cable-based wired communication module.
When the patient monitoring device 100 is a monitor, the data acquisition module 110 may include sensors coupled to the monitor. The sensors may be connected to the controller 130 of the monitor by a wired communication protocol or a wireless communication protocol, so that data interaction may be performed between the sensors and the controller 130. In particular, the sensor is used to collect monitored data of vital sign parameters of a patient. The vital sign parameters may include, but are not limited to, one or more of electrocardiography, respiration, blood oxygen saturation, heart rate, pulse, body temperature, non-invasive blood pressure, end-tidal carbon dioxide, respiratory mechanics parameters, anesthetic gases, cardiac output, brain electrical double frequency index, and the like. In some embodiments, the sensor may be provided separately from the patient monitoring device 100 and removably coupled to the patient monitoring device 100. The monitored data of the embodiment of the invention comprises the original data of vital sign parameters collected by the sensor and/or the results after processing the original data, such as parameter values, waveforms, change trends, event alarms, patient state evaluation results and the like.
Illustratively, the data acquisition module 110 may also include a communication module coupled to the controller 130. The data acquisition module 110 acquiring the monitored data may include the communication module receiving the monitored data acquired and transmitted by the other device via a communication connection established with the other device. For example, the central station can acquire monitoring data sent by the bedside monitor and the mobile monitor through the communication module; for another example, the bedside monitor may obtain the monitored data sent by the mobile monitor and the central station through the communication module.
The output device 120 includes at least a display for providing visual display output to a user. In particular, the display may be used to provide a visual display interface for a user, including but not limited to a monitoring interface, a parameter setting interface, an alarm setting interface, and the like. The monitoring interface displayed by the display is used for displaying the monitoring data of the physiological parameters. The display may be implemented as a touch display, or as a display with an input panel, i.e. the display may also be an input device, for example.
The output device 120 may include an audio output device, an indicator light, a printer, etc., in addition to a display. The audio output device can be used for outputting alarm sound, and the indicator lamp can be used for light prompt information, so that medical staff can execute corresponding rescue measures, and the condition of a patient and the working state of equipment can be known in real time, thereby avoiding the negligence phenomenon of the medical staff or the patient, and improving the monitoring safety. The information output by the output device 120 is not limited to alarm prompts, and for example, the audio output device may also be used to output operation prompt tones, on-off prompt tones, and the like.
To enable user interface and data exchange, the patient monitoring device 100 may include other input means in addition to the display 110 connected to the controller 130 for a user to input operational instructions. Other input devices include, but are not limited to, a keyboard, mouse, trackball, joystick, remote control, and the like. The input device may be used to obtain an alarm reset operation by the user.
The controller 130 of the patient monitoring device 100 can be a central processing unit (Central Processing Unit, CPU), but can also be other general purpose processors, digital signal processors (Digital Signal Processor, DSPs), application specific integrated circuits (Application Specific Integrated Circuit, ASICs), field-programmable gate arrays (Field-Programmable Gate Array, FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or the like. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like. The controller 130 is a control center of the patient monitoring device 100 and connects various portions of the overall patient monitoring device 100 using various interfaces and lines.
The patient monitoring device 100 also includes a memory. The memory stores program codes, and the controller 130 is configured to call the program codes in the memory to perform steps in a display method described below. The memory may be used to store patient monitoring data. The memory may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, application programs required for a plurality of functions, and the like; the data storage area may store data based on monitoring, etc. In addition, the memory may include high-speed random access memory, and may also include non-volatile memory, such as a hard disk, memory, plug-in hard disk, smart Media Card (SMC), secure Digital (SD) Card, flash Card (Flash Card), multiple disk storage devices, flash memory devices, or other volatile solid-state storage devices.
Referring to fig. 2, a flow chart of a patient monitoring device 100 outputting alarm information is shown in accordance with an embodiment of the present invention. Specifically, the controller 130 first determines whether the monitored data of the currently monitored physiological parameter of the at least one item target meets the first alarm condition; when the monitored data of the currently monitored physiological parameter of the at least one item target is judged to meet the first alarm condition, the output device 120 is controlled to output the first alarm information. As shown in fig. 3, during the period from T0 to T1, the monitored data of at least one item of physiological parameter satisfies the first alarm condition, and the control device 120 continuously outputs the first alarm information during the period.
Wherein the first alarm condition may be a first overrun alarm condition. The first overrun alarm condition is used for monitoring whether the monitored data exceeds a certain alarm threshold, and specifically, the monitored data meeting the first alarm condition may be that the monitored data is greater than a first alarm upper limit threshold or that the monitored data is less than a first alarm lower limit threshold; the range between the first alarm upper limit value and the first alarm lower limit value is the normal range of the monitored data. For example, the first overrun alarm condition may include a heart rate greater than 120bpm, and the monitored data determining the heart rate parameter satisfies the first alarm condition when the heart rate value exceeds 120bpm, and the controller 130 controls the output device to output the first alarm information.
Alternatively, the first alarm condition comprises a first abnormal event alarm condition. The first abnormal event alert condition is for monitoring whether an abnormal event has occurred based on the monitored data of the one or more physiological parameters. For example, the first abnormal event alert condition may include a waveform analysis rule corresponding to an abnormal event, and the controller 130 may extract a waveform feature from a waveform curve of the physiological parameter based on the waveform analysis rule, and determine whether the abnormal event corresponding to the waveform analysis condition occurs according to the waveform feature. For example, the controller 130 may analyze the waveform profile of the electrocardiographic parameter to determine whether a ventricular rate event has occurred. Alternatively, the first abnormal event alert condition may include a combined alert condition for a plurality of physiological parameters, for example, if the heart rate value is greater than 100bpm but less than 120bpm, the first overrun alert condition corresponding to the heart rate parameter is not met, but if the heart rate value is greater than 120bpm while the arterial pressure is less than 90 and the respiratory rate is greater than 22, the first abnormal event alert condition may be determined to be currently met based on the monitored data for heart rate, arterial pressure, and respiratory rate.
The first alarm information illustratively includes at least a first alarm identification displayed by the display. The first alarm identifier comprises a first alarm character string for describing an alarm cause, which is usually that the current monitored data meets a certain preset alarm condition. Illustratively, when the first alarm condition triggering the first alarm information is a first overrun alarm condition, the first alarm string includes a string for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first overrun alarm condition, such as "HR too high" or "HR > 120". When the first alarm condition triggering the first alarm information is a first abnormal event alarm condition, the first alarm string includes a string for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first abnormal event alarm condition, such as "room speed", "HR > 100, with Art-Sys < 90, RR > 22". Of course, the above first alarm string is only an example, and the first alarm string only needs to be able to describe the reason of the alarm, so that the medical staff can execute the corresponding rescue measures.
In addition to the first alarm string, the first alarm tag may further comprise a graphic of a preset color and shape displayed below the alarm string, i.e., the first alarm string may have a preset ground color, in order to draw attention of the medical staff. For example, the first alarm tag may include a red rectangular tag, and a white character string displayed in the red rectangular tag. The first alarm tag may be displayed in an alarm information display area of the monitoring interface, which may be located in a top information bar of the monitoring interface. In some embodiments, the alert details may also be displayed in response to a selection operation of the first alert identification.
In addition to displaying the first alarm identification, the controller 130 may control the display to display the monitored data of the target physiological parameter in a first highlighted manner in the monitoring interface, so that the medical staff can quickly determine the target physiological parameter and the monitored data thereof that trigger the alarm. The first highlighting mode comprises highlighting, amplifying, displaying, changing color, adding ground color below the numerical value, displaying a specific mark near the numerical value and the like of the monitored data of the target physiological parameter.
Because the alarm reset operation of the user is not obtained when the first alarm information is output, and the first alarm information is triggered by the first alarm condition which is difficult to meet, the first alarm information needs to be presented in a more prominent mode. Therefore, the first alarm information can also comprise an alarm sound output by the audio output device, and/or the first alarm information can also comprise a lamplight prompt information output by the indicator lamp so as to further draw attention of medical staff.
In outputting the first alarm information, the controller 130 may also acquire an alarm reset operation of the user. As shown in FIG. 4, the alarm reset operation of the embodiment of the present invention may be obtained by an alarm reset key 410 located in the monitoring interface or an alarm reset key of the entity, or may be obtained by other means. For example, the alarm reset operation may also be obtained by an alarm confirm key, an alarm pause key, an audio off key, a ring cancellation key, an alarm inhibit key, or a custom reset button. The alarm reset operation of the embodiment of the present invention may be any operation capable of indicating that the user has known the first alarm information, and is not limited to the selection operation of the alarm reset key 410.
The controller 130 is further configured to control the output device 120 to output the second alarm information in response to the alarm reset operation. The acquired alarm reset operation of the user indicates that the user has acquired the first alarm information, but the monitored data of the target physiological parameter is still likely to meet the first alarm condition at the moment, so as to avoid forgetting or neglecting the alarm of the user and cause clinical risks, and therefore, the second alarm information is continuously output after the acquired alarm reset operation of the user. However, since the user already knows the alarm, in order to reduce the alarm fatigue, the second alarm information may be presented in a relatively weak manner, that is, the original first alarm information has a more prominent manner than the current second alarm information, so that the current second alarm information is not so strong as compared with the first alarm information, and does not cause special attention, dislike or alarm fatigue of medical staff.
With continued reference to fig. 3, at time T1, the controller 130 acquires an alarm reset operation of the user, and during the periods T1 to T2, the monitored data of at least one item of physiological parameter still satisfies the first alarm condition, and the controller 130 controls the output device 120 to change the output alarm information from the first alarm information to the second alarm information.
The second alarm information illustratively includes a second alarm identification displayed by the display. With continued reference to fig. 4, the second alarm tag 420 may be displayed at the same display location as the first alarm tag, both of which are displayed in the alarm information display area of the monitoring interface. The second alarm tag includes a second alarm string 421 and a reset response flag 422 for characterizing an alarm reset operation.
During the period from T1 to T2, the monitored data of the physiological parameter of the at least one item target still satisfies the first alarm condition, and thus the second alarm string may be identical to the first alarm string. In particular, when the first alarm condition is a first overrun alarm condition, the second alarm string comprises a string for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first overrun alarm condition, e.g. the second alarm string is still "HR too high" or "HR > 120". When the first alarm condition is a first abnormal event alarm condition, the second alarm string includes a string, such as "room speed", for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first abnormal event alarm condition. Furthermore, the second alarm string may have the same color and/or the same ground color as the first alarm string. Of course, the second alarm string and the first alarm string may also have different colors and/or different ground colors.
The reset response flag 422 may be a check number displayed before the second alarm string as shown in fig. 4, but is not limited thereto. The reset response flag 422 may be a variety of geometric patterns or characters that indicate that an alarm reset operation by the user has been obtained. The reset response flag 422 may be displayed to the left, right, or above or below the second alarm string. The embodiment of the invention does not limit the type and the display position of the reset response mark.
For example, the base color of the first alarm tag and/or the second alarm tag may depend on the alarm type or alarm level. For example, the alarm levels include three kinds of low-level alarms, medium-level alarms and high-level alarms, and different alarm levels correspond to different ground colors. The alarm types may include technical alarms, overrun alarms, event type alarms, etc., with different alarm types corresponding to different ground colors. Referring to fig. 5, second alarm identifications corresponding to the technical alarm, the overrun alarm and the event type alarm are respectively shown.
In addition to the second alarm identification, controlling the output device 120 to output the second alarm information may further include controlling the display to display the monitored data of the target physiological parameter in a second highlighting manner in the monitored interface. The second highlighting may be the same as the first highlighting, e.g., both include a base color that displays the monitored data of the target physiological parameter as an alarm level. The second highlighting mode may also be different from the first highlighting mode, for example, the first highlighting mode includes displaying the monitored data of the target physiological parameter as an alarm-level ground color and blinking, and the second highlighting mode includes displaying the monitored data of the target physiological parameter as an alarm-level ground color, but does not blinking.
There are a number of implementations in which the first alarm information is presented in a more prominent manner than the second alarm information. For example, the first alarm information includes alarm sound and/or light prompt information, and the second alarm information may include only the second alarm identifier displayed by the display, that is, the alarm sound and/or light prompt information is stopped after the alarm reset operation input by the user is acquired, so as to avoid causing alarm fatigue of medical staff. Alternatively, both the first alarm information and the second alarm prompting information may include alarm sounds, but the first alarm information includes alarm sounds played at a larger volume, or more urgent alarm sounds are played, so that the alarm information is presented more prominently.
Alternatively, a more prominent presentation may include a more prominent visual effect. For example, the first alarm tag may have a higher flashing frequency than the second alarm tag, or the first alarm tag may flash while the second alarm tag may not flash, or the base color of the first alarm tag may be more visible than the base color of the second alarm tag, or the first alarm tag may have a larger graphic or font than the second alarm tag, etc.
The controller 130 is further configured to trigger an alarm delay setting in response to an alarm reset operation such that an alarm delay is performed when the monitored data of the at least one subject physiological parameter no longer satisfies the first alarm condition. Specifically, during the outputting of the second alarm information, the controller 130 determines whether the monitored data of the currently monitored at least one physiological parameter satisfies the first alarm condition, and determines whether the monitored data of the currently monitored at least one physiological parameter satisfies the second alarm condition, wherein the second alarm condition is more easily satisfied than the first alarm condition. Specifically, the controller 130 may determine whether the monitored data of the currently monitored at least one physiological parameter satisfies the second alarm condition when it is determined that the monitored data of the currently monitored at least one physiological parameter does not satisfy the first alarm condition. If the monitored data of the currently monitored physiological parameter of the at least one item target does not meet the first alarm condition but meets the second alarm condition, the output device 120 is controlled to output third alarm information. Otherwise, if the controller does not acquire the alarm reset operation of the user in the process of outputting the first alarm information, the controller can directly contact with the alarm when judging that the monitored data of the currently monitored at least one physiological parameter does not meet the first alarm condition.
The second alarm condition may include a second overrun alarm condition, and may include a second upper alarm threshold and/or a second lower alarm threshold. The second alarm condition may be more readily satisfied than the first alarm condition by either the second upper alarm threshold being below the first upper alarm threshold or the second lower alarm threshold being below the first lower alarm threshold. For example, when the first overrun alarm condition is a heart rate greater than 120bpm, the second overrun alarm condition may be a heart rate value in the interval 115bpm-120 bpm.
The second alarm condition may also include a second abnormal event alarm condition. For example, when the second abnormal event alarm condition includes a waveform analysis condition corresponding to the abnormal event, the same waveform may be analyzed based on the first abnormal event alarm condition, and the determination result is that no abnormal event exists, and when the waveform is analyzed based on the second abnormal event alarm condition, the determination result may be that an abnormal event exists.
For example, the second alarm condition may be preset, and when the controller 130 determines that the monitored data of the currently monitored target physiological parameter does not satisfy the first alarm condition, the preset second alarm condition is invoked to determine whether the monitored data of the currently monitored target physiological parameter satisfies the second alarm condition. Alternatively, the second alarm condition may be obtained by adjusting the first alarm condition, for example, when the controller 130 determines that the monitored data of the currently monitored target physiological parameter does not satisfy the first alarm condition, the first alarm condition is adaptively adjusted to be more easily satisfied, for example, the first alarm upper limit threshold is reduced or the alarm lower limit threshold is increased by a certain proportion, and the adjusted first alarm condition constitutes the second alarm condition. The controller 130 then determines whether the monitored data of the currently monitored target physiological parameter satisfies a second alarm condition.
Referring to fig. 3, during T2 to T3, the controller 130 determines that the monitored data of the currently monitored physiological parameter of the at least one item does not satisfy the first alarm condition, but satisfies the second alarm condition, and thus controls the output device 120 to output the third alarm information during this period. The phase of outputting the third alarm information is the alarm delay phase, frequent presentation of transient alarms can be reduced through alarm delay, and although the alarm time is also increased, because the alarm delay of the embodiment of the invention combines the alarm reset operation of a user, the third alarm information output in the alarm delay phase has a relatively unobtrusive presentation mode, and thus the alarm fatigue can be effectively avoided.
The third alarm information may be the same as the second alarm information described above, and specifically, the third alarm information may include a second alarm identifier, where the second alarm identifier includes a second alarm string and a reset response flag for characterizing an alarm reset operation, and the second alarm string includes a string for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first overrun alarm condition, or includes a string for characterizing that monitored data of the currently monitored at least one physiological parameter satisfies the first abnormal event alarm condition. That is, although the monitored data of the target physiological parameter does not satisfy the first alarm condition when the third alarm information is output, the third alarm information may still characterize that the monitored data of the target physiological parameter satisfies the first alarm condition in order to maintain the consistency of the alarm.
Alternatively, the third alarm information may be different from the second alarm information, but in other presentation manners that are less prominent than the first alarm information. The third alarm information illustratively includes a third alarm identifier displayed by the display, the third alarm identifier including a third alarm string and a reset response flag for characterizing an alarm reset operation. For example, the third alarm string may be different from the second alarm string, e.g., the third alarm string comprises a string for characterizing that the monitored data of the currently monitored at least one physiological parameter meets the second overrun alarm condition, or the third alarm string comprises a string for characterizing that the monitored data of the currently monitored at least one physiological parameter meets the second abnormal event alarm condition. That is, the third alarm information characterizes that the target physiological parameter meets the second alarm condition, so that the third alarm identifier can be prevented from being in conflict with the monitoring data of the physiological parameter displayed in the monitoring interface. Alternatively, the third alarm string may be identical to the second alarm string, but the third alarm string and the second alarm string may be displayed in different colors and/or different ground colors to distinguish between a normal alarm phase and an alarm delay phase.
In the process of outputting the third alarm information, the controller 130 is further configured to determine whether the monitored data of the currently monitored physiological parameter of the at least one item target meets the first alarm condition again; if the monitored data of the at least one item target physiological parameter currently monitored is judged to meet the first alarm condition again, the controller 130 controls the output device 120 to output the second alarm information again, so that the front alarm stage and the rear alarm stage are connected through the alarm delay stage for outputting the third alarm information, the alarm times are reduced, and alarm fatigue is avoided. When the monitored data of the target physiological parameter meets the first alarm condition again, the alarm information output by the output device 120 is the second alarm information, that is, the previous alarm reset operation is still effective, and the user is not required to perform alarm reset again.
As shown in fig. 3, at time T4, the controller 130 determines that the monitored data of the target physiological parameter satisfies the first alarm condition again, and T4 < T3, so that the output device 120 outputs the second alarm information again during the period T4 to T5. From the perspective of a user, after the alarm is reset at the moment T1, the output device outputs alarm information in a non-protruding mode all the time, so that the continuity of the alarm can be maintained, the interference to the user can be reduced, and the alarm fatigue is avoided. After the user carries out alarm reset at the moment T1, the output device can still keep the alarm information presentation mode after the alarm reset in the period from T4 to T5, the user does not need to carry out alarm reset again, and the user is prevented from frequently carrying out alarm reset in a short time.
The controller 130 is further configured to determine whether the time for outputting the third alarm information reaches the first time, and when the time for outputting the third alarm information reaches the first time, if the monitored data of the physiological parameter of the at least one item does not satisfy the first alarm condition, the controller 130 controls the output device to stop outputting the third alarm information. That is, the time for outputting the third alarm information is the first time at the maximum, if the monitored data of the target physiological parameter meets the first alarm condition again before that, the controller 130 controls the output device 120 to output the second alarm information again, and if the monitored data of the target physiological parameter does not meet the first alarm condition all the time in the first time, the controller 130 controls the output device to stop alarming. After stopping outputting the third alarm information, the alarm reset operation is also disabled accordingly, and the controller 130 continues to determine whether the monitored data of the currently monitored physiological parameter of the at least one item target meets the first alarm condition, and outputs the first alarm information when the monitored data of the currently monitored physiological parameter of the at least one item target meets the first alarm condition.
In some embodiments, the controller 130 may also turn on the alarm delay setting when no alarm reset operation is obtained. Specifically, if the controller 130 does not acquire the alarm reset operation in the process of outputting the first alarm information, it may also determine whether the monitored data of the currently monitored physiological parameter of the at least one item target meets the second alarm condition when determining that the monitored data of the currently monitored physiological parameter of the at least one item target does not meet the first alarm condition; when the controller 130 determines that the monitored data of the currently monitored physiological parameter of the at least one item target does not meet the first alarm condition but meets the second alarm condition, the output device 120 is controlled to output fourth alarm information. And outputting the fourth alarm information, namely an alarm delay stage. For example, the first alarm information may be presented in a more prominent manner than the fourth alarm information, which may be the same as the second alarm information or the third alarm information, for example. Alternatively, the fourth alarm information may be identical to the first alarm information in order to maintain consistency of the alarm information.
In outputting the fourth alarm information, the controller 130 determines whether the monitored data of the currently monitored physiological parameter of the at least one item target meets the first alarm condition again. And if the monitored data of the at least one item target physiological parameter which is currently monitored is judged to meet the first alarm condition again, controlling the output device to output the first alarm information. When the time of outputting the fourth alarm information reaches the second time, if the monitored data of the currently monitored physiological parameter of the at least one item does not meet the first alarm condition yet, the output device 120 is controlled to stop outputting the fourth alarm information. The longest time of outputting the fourth alarm information is the second time, if the monitored data of the target physiological parameter in the second time meets the first alarm condition again, the first alarm information is continuously output, so that two alarms with short duration are connected into one alarm with longer duration; and stopping alarming if the monitored data of the target physiological parameter does not meet the first alarming condition all the time in the second time.
Wherein, because the output of the fourth alarm information is not combined with the alarm reset operation of the user, the second time for outputting the fourth alarm information is shorter. Specifically, the length of the second time is less than the length of the first time. For example, the first time is 30s and the second time is 3s-5s. The fourth alarm information can be used for linking two alarms with shorter time intervals, so that frequent alarms are prevented when the monitored data of the target physiological parameter shakes up and down under the first alarm condition.
The controller 130 is also illustratively configured to control the display to display an alarm setting interface for setting parameters associated with the alarm delay. Specifically, the second alarm condition may be set according to the setting operation based on the alarm setting interface receiving the setting operation of the second alarm condition, or the first time may be set according to the setting operation based on the alarm setting interface receiving the setting operation of the first time at which the third alarm information is output. The second alarm condition and/or the first time may also be fixed or automatically set by the controller 130 according to certain rules. Illustratively, the greater the difference between the second alarm condition and the first alarm condition, the lower the accuracy of the alarm and therefore the shorter the length of the first time.
Several exemplary alarm procedures for the patient monitoring device 100 of an embodiment of the present invention are shown below:
1. the current heart rate value of the patient is 126bpm, the first alarm condition is that the heart rate value is higher than 120bpm, and the controller 130 judges that the current heart rate value of the patient meets the first alarm condition, so that first alarm information representing that the heart rate is too high is output;
acquiring alarm reset operation of a user in the process of outputting the first alarm information;
After the alarm reset operation of the user is acquired, the controller 130 controls the output device to change from the first alarm information to the second alarm information, for example, stops the audible and visual alarm, and adds a mark of "adopting the second alarm condition when the current heart rate value of the patient does not meet the first alarm condition";
when the heart rate value of the patient is not higher than 120bpm (for example, the heart rate value is reduced to 118 bpm), judging whether the heart rate value meets the second alarm condition according to the mark of 'adopting the second alarm condition when the current heart rate value of the patient does not meet the first alarm condition': the heart rate value is 115bpm-120bpm. The controller 130 determines that the heart rate value satisfies the second alarm condition, and continues to output the third alarm information 30s.
2. The current heart rate value of the patient is 126bpm, the first alarm condition is that the heart rate value is higher than 120bpm, and the controller 130 judges that the current heart rate value of the patient meets the first alarm condition, so that first alarm information representing that the heart rate is too high is output;
