detailed description

Embodiments of the present invention provide a method and device for setting an alarm limit value of a monitoring device, monitoring equipment, a computer device, and a readable storage medium, which are used to avoid a situation in which an alarm limit value is not set for a patient due to human error. It is helpful to reduce the waste of medical resources or delay the medical condition.

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all的实施例。 Examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects without using To describe a specific order or sequence. It should be understood that the data so used can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order other than what is illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, processes, methods, products or equipment that include a series of steps or units are not necessarily limited to those steps that are clearly listed Or units, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or equipment.

During the hospitalization of the patient, in order to facilitate the medical staff to understand the patient's condition, the monitoring equipment is generally connected to the patient. The monitoring equipment can automatically detect the vital signs of the patient, for example, output the effective data of the vital signs, such as the display device of the monitoring device Display the effective data of vital signs, so that the medical staff who patrol near the patient can understand the patient's condition, or send the effective data of vital signs to other terminals, such as nurse station, central station, medical tablet, etc., to facilitate the medical staff View the patient's condition remotely. The deterioration of the patient's condition is often sudden. When the condition deteriorates, if the medical staff can treat the patient in time, it will greatly reduce the risk of the patient's condition deterioration or even death. For this reason, existing monitoring equipment is often set There is an alarm function. When the effective data of vital signs detected by the monitoring device exceeds the alarm limit of the vital signs, the monitoring device will start an alarm to notify the medical personnel to view and treat the patient corresponding to the monitoring device.

Reasonable setting of the alarm limit is very important to improve the effectiveness of the alarm function. If the alarm limit is set too close to the effective data of the vital signs in the stable state of the disease (for the convenience of description, the effective of the vital signs in the stable state of the disease The data is called the standard data of vital signs), then the patient’s small fluctuations in vital signs in a stable condition will trigger the monitoring equipment to start an alarm, allowing medical personnel to come to check, wasting medical resources; if the alarm limit is set too far The standard data of vital signs, it is easy to appear when the patient's vital signs fluctuate greatly, but the monitoring device does not trigger the alarm, and the large range of vital signs fluctuations often indicate that the patient's condition has deteriorated, which is easy to cause medical staff to be unable to The patient was treated in a timely manner. Due to the differences between individuals, the standard data of vital signs of different patients often have large differences. For example, the standard data of Zhang San’s heart rate (HR/PR) is lower at 60 bmp, while the standard data of Li Si’s heart rate is higher. , 90bmp. It can be seen that for the reasonable setting of the alarm limit, the first thing is to determine the standard data of the patient's vital signs, and then the alarm limit needs to be set according to the standard data of the patient's vital signs.

To this end, after connecting the monitoring equipment to the patient, the medical staff needs to manually set the alarm limit of the monitoring equipment. For example, the medical staff needs to first observe the effective data of the vital signs output by the monitoring equipment, as the standard data of the patient's vital signs, and according to The standard data of the patient’s vital signs manually sets the upper and lower alarm limits. These upper and lower limits are collectively referred to as the alarm limits, or the medical staff manually turns on the automatic setting of the alarm limits, and then the monitoring equipment will be based on the effectiveness of the acquired vital signs Data, calculate the alarm limit corresponding to the vital signs according to the preset algorithm, and set the alarm limit according to the calculation result.

However, human operation inevitably has a certain error rate. After connecting the monitoring device to the patient, the medical staff may forget to manually set the alarm limit. At this time, the monitoring device fails to set the alarm limit according to the standard data of the patient's vital signs Generally, the alarm function is executed according to the default fixed alarm limit. For this patient, the default alarm limit is very likely to be unreasonable, resulting in a false alarm or a situation that delays the condition. Moreover, the characteristics of each patient are different. Therefore, the default alarm settings are used uniformly, which will inevitably have the problems of wasting medical resources and increasing the workload of medical care. More seriously, it will ignore the changes in the condition of special patients and cause medical risks. In order to solve the above problems, the present invention provides a method for setting the alarm limit value of the monitoring device, which is used to avoid unreasonable situations where the alarm limit value of the monitoring device is caused by human error. The above method usually runs on the patient monitor.

Figure 1 provides a system framework diagram of a multi-parameter monitor or module assembly. The multi-parameter monitor or module assembly includes at least a parameter measurement circuit 912. The parameter measurement circuit 912 includes at least one parameter measurement circuit corresponding to physiological parameters. The parameter measurement circuit 912 includes at least an electrocardiogram signal parameter measurement circuit, a respiratory parameter measurement circuit, a body temperature parameter measurement circuit, a blood oxygen parameter measurement circuit, a non-invasive blood pressure parameter measurement circuit, There is at least one parameter measurement circuit among invasive blood pressure parameter measurement circuits and the like, and each parameter measurement circuit 912 is connected to a sensor accessory 911 inserted externally through a corresponding sensor interface. The sensor accessory 911 includes a detection accessory corresponding to the detection of physiological parameters such as electrocardiographic respiration, blood oxygen, blood pressure, and body temperature. The parameter measurement circuit 912 is mainly used to connect the sensor accessory 911 to obtain the collected physiological parameter signals, and may include at least two or more physiological parameter measurement circuits. The parameter measurement circuit 912 may be, but not limited to, a physiological parameter measurement circuit (module), Human physiological parameter measurement circuit (module) or sensor collects human physiological parameters and so on. Specifically, the parameter measurement circuit 912 obtains an external physiological parameter sensor accessory through an extended interface to obtain physiological sampling signals about the patient, and obtains physiological data after processing for alarm and display. The extended interface can also be used to output the control signal about how to collect physiological parameters output by the main control circuit to the external physiological parameter monitoring accessory through the corresponding interface to realize the monitoring and control of the patient's physiological parameters.

The multi-parameter monitor or module component may also include a main control circuit 913, which needs to include at least one processor and at least one memory. Of course, the main control circuit 913 may also include a power management management module, a power IP module, and an interface conversion At least one of circuits and the like. The power management module is used to control the power on/off of the whole machine, the power-on sequence of each power domain inside the board, and battery charging and discharging. The power IP module refers to correlating the schematic diagram of the power circuit unit that is frequently called repeatedly and the PCB layout, and curing into a separate power module, that is, converting an input voltage into an output voltage through a predetermined circuit, wherein the input voltage and The output voltage is different. For example, convert a 15V voltage to 1.8V, 3.3V, or 3.8V. It can be understood that the power IP module may be single-channel or multi-channel. When the power IP module is single, the power IP module can convert an input voltage to an output voltage. When the power IP module is multi-channel, the power IP module can convert one input voltage to multiple output voltages, and the voltage values of the multiple output voltages can be the same or different, so as to meet the needs of multiple electronic components at the same time. Voltage demand, and the module has few external interfaces, working in the system is a black box decoupled from the external hardware system, improving the reliability of the entire power system. The interface conversion circuit is used to convert the signal output by the main control minimum system module (that is, at least one processor and at least one memory in the main control circuit) into the input standard signal required by the actual external device, for example, supporting external VGA display The function is to convert the RGB digital signal output from the main control CPU to a VGA analog signal, support external network functions, and convert the RMII signal to a standard network differential signal.

In addition, the multi-parameter monitor or module component may also include one or more of a local display 914, an alarm circuit 916, an input interface circuit 917, an external communication, and a power interface 915. The main control circuit is used to coordinate and control each board, circuit and equipment in the multi-parameter monitor or module assembly. In this embodiment, the main control circuit is used to control the data interaction between the parameter measurement circuit 912 and the communication interface circuit, as well as the transmission of control signals, and send the physiological data to the display 914 for display, or it can be received from the touch screen or User control commands input by physical input interface circuits such as keyboards and keys can of course also output control signals on how to collect physiological parameters. The alarm circuit 916 may be an audible and visual alarm circuit. The main control circuit completes the calculation of physiological parameters, and can send the calculation results and waveforms of the parameters to the host (such as the host with a display, PC, central station, etc.) through external communication and power interface 915, external communication and power interface 915 It can be one or a combination of LAN interfaces composed of Ethernet (Token), Token Ring (Token Ring), Token Bus (Token Bus), and the Backbone Network Fiber Distributed Data Interface (FDDI) as the three networks. It can also be one or a combination of wireless interfaces such as infrared, Bluetooth, wifi, and WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB. The external communication and power supply interface 915 may also be one or a combination of two of a wireless data transmission interface and a wired data transmission interface. The host computer can be any computer equipment such as the host computer of the monitor, the electrocardiograph, the ultrasound diagnostic apparatus, and the computer. By installing the matched software, a monitor device can be formed. The host can also be a communication device, such as a mobile phone, a multi-parameter monitor, or a module component, which sends data to a mobile phone that supports Bluetooth communication through a Bluetooth interface, so as to realize remote transmission of data.

The multi-parameter monitoring module component can be set outside the monitor casing. As an independent external parameter module, it can be inserted into the monitor host (including the main control board) to form a plug-in monitor as part of the monitor, or It can be connected to the host of the monitor (including the main control board) through a cable, and the external parameter module is used as an external accessory of the monitor. Of course, parameter processing can also be built into the housing, integrated with the main control module, or physically separated within the housing to form an integrated monitor.

Please refer to FIG. 2A, which provides a method for setting an alarm limit of a monitor device, which includes:

Step 100: Obtain data of at least one vital sign through a sensor accessory provided on the patient's body.

The monitoring equipment includes a monitor worn by the patient and any one of the bedside monitors. The monitoring equipment usually establishes a signal connection with one or more sensors or sensor accessories. The sensor or sensor accessories include one or more ECG electrodes and voltage Sensors, blood oxygen saturation SpO2 sensors, pulse sensors, thermometers, breathing sensors, exhaled gas sensors, non-invasive blood pressure sensors, etc. After the medical personnel turn on the monitoring device, the sensor or sensor accessory can be set on the patient's body, and the monitoring device can detect the data of at least one vital sign of the patient through the sensor or sensor accessory, for example, the patient's body temperature and heart rate can be obtained Vital signs such as electrical waveforms and pulse shape. The vital signs mentioned in this article include at least one of body temperature, electrocardiogram, blood oxygen, blood pressure, electroencephalogram, blood glucose and breathing. Of course, in one of the embodiments, step 100 is mainly completed by the aforementioned processor in FIG. 1.

In this step, the data for obtaining at least one vital sign is obtained through a sensor accessory provided on the patient's body, but the obtained data for at least one vital sign can be transmitted to the monitoring device by wired or wireless means. It may be that the monitoring device is obtained through a sensor accessory locally connected to the device, or the vital signs data collected from the remote sensor accessory is obtained through the network side.

Step 200: Determine that valid data corresponding to at least one vital sign within a period of time is continuously obtained.

Before step 200, the monitoring device is connected with the sensor accessory, the processor or the monitoring device receives the detection signal from the sensor accessory, and obtains data of at least one vital sign according to the detection signal, which may include valid data and invalid data. The processor or the monitoring device may also recognize whether the obtained vital sign data is valid data or invalid data, and automatically execute the above step 100 according to the recognized valid data. The valid data mentioned in this article refers to the vital sign data measured by the monitoring equipment and can provide valuable evaluation information for the user to evaluate the patient's state, for example, the corresponding value is displayed in the trend table of the data review at the corresponding time; otherwise, Invalid data refers to the measurement data measured by the monitoring equipment and cannot provide valuable evaluation information for the user to evaluate the patient's status. For example, in the trend table of the data review, there is no value display at the corresponding time, or there is an invalid logo display at the corresponding time. Or there may be technical alarms such as excessive interference and lead fall-off at the corresponding time.

When it is recognized that the monitoring equipment has continuously obtained valid data of vital signs for a period of time, it is considered to automatically calculate the recommended value of the alarm limit, so that the alarm limit indicated can be credible and have practical clinical value. The period of time mentioned in this embodiment may be an indefinite time period of 1 second, 2 seconds, 10 milliseconds, 2 milliseconds, etc., which may be set by the user, or the system default setting.

In another embodiment, as shown in FIG. 2B before or after step 100, the following step 2B-1 may also be included:

Detect whether the connection between the patient and the monitoring equipment has changed;

When it is detected that the connection relationship between the patient and the monitoring device changes, the data of at least one vital sign is obtained through a sensor attachment provided on the patient's body, which is used to determine whether at least one vital sign is continuously obtained for a period of time Corresponding valid data, and then perform the above steps 200 and

subsequent steps

300, 400 and so on. Of course, when it is determined that valid data corresponding to at least one vital sign within a certain period of time has not been continuously acquired, it still returns to repeat the above step 100, and continues to obtain data of at least one vital sign through a sensor attachment provided on the patient's body ;

When it is not detected that the connection relationship between the patient and the monitoring device has not changed, the calculation of the recommended alarm limit value will not be performed.

The change in the connection relationship between the patient and the monitoring device means that at least one of the following conditions occurs:

1. The monitoring equipment starts up or restarts the measurement;

2. The sensor attachment of the monitoring device begins to establish a connection with the patient's body, and can perform data transmission with the monitoring device;

3. Complete the import of new patient information in the monitoring equipment;

4. After the sensor accessory is disconnected, re-establish connection with the monitoring equipment to obtain physiological sign data;

5. When switching from the first patient to the second patient in the monitoring device.

Of course, the above situation cannot be exhaustive, as long as it can be used to prompt that the patient corresponding to the monitoring device may change, it can be deemed that the connection relationship between the patient and the monitoring device has changed. Therefore, when the connection relationship between the patient and the monitor changes, the monitoring device can provide the user with the calculation of the recommended value of the alarm limit, thereby ensuring that the patient's threshold setting function can be personalized. The connection relationship between the patient and the monitoring device mentioned in this article includes the working state of the monitoring device, the pairing relationship between the patient and the monitoring device, and the link state between the patient and the monitoring device through the sensor accessory. Therefore, Changes in the working state of the monitoring device, the pairing relationship between the patient and the monitoring device, and the link status between the patient and the monitoring device connected by the sensor accessory can be considered as a change in the connection relationship between the patient and the monitoring device. The working state of the monitoring device changes, it can be the monitoring device is turned on, or it can be clicked to restart the measurement. The state of the link between the patient and the monitoring device through the sensor accessory changes. It can be that the sensor accessory of the monitoring device begins to establish a connection with the patient's body, and can transmit data with the monitoring device, or it can be the sensor accessory after re-attachment Establish a connection with the monitoring equipment to obtain physiological sign data. The pairing relationship between the patient and the monitoring device changes, which may be the introduction of new patient information in the monitoring device, or it may be when switching from the first patient to the second patient in the monitoring device.

Specifically, in one specific embodiment, the following steps may be included before or after step 100:

Detect whether the pairing relationship between the patient and the monitoring device has changed,

When it is detected that the pairing relationship between the patient and the monitoring device is changed, data of at least one vital sign is obtained through a sensor attachment provided on the patient's body, and valid data corresponding to the at least one vital sign is obtained to determine whether to continue Obtain valid data corresponding to at least one vital sign within a period of time, and then perform the above step 200 to determine whether to calculate the recommended value of the alarm limit. Of course, when it is determined that valid data corresponding to at least one vital sign within a certain period of time has not been continuously obtained, the procedure returns to the above step 100 and continues to obtain data of at least one vital sign through a sensor attachment provided on the patient's body;

When it is not detected that the pairing relationship between the patient and the monitoring device has changed, the procedure returns to step 100, and continues to obtain data of at least one vital sign through a sensor accessory provided on the patient's body.

Usually a patient is paired with a monitoring device, and the patient and the monitoring device are connected by a sensor accessory. Therefore, when the one-to-one pairing relationship between the patient and the monitoring device changes, it is considered that the pairing relationship between the patient and the monitoring device has changed. In this embodiment, by clearly confirming that the pairing relationship between the patient and the monitoring device has changed, and then performing the calculation of the recommended value, unnecessary double calculation and setting of the alarm limit can be effectively avoided, which can be more targeted Implementation of personalized threshold adjustments.

Of course, in another embodiment, as shown in FIG. 2C, when the monitoring device detects a change in the connection relationship between the patient and the monitoring device, data of at least one vital sign is obtained through a sensor attachment provided on the patient’s body, The monitoring device can automatically determine whether the data of the detected vital signs is stable. If it is stable, it may consider calculating the recommended values of the alarm limits corresponding to at least one vital sign based on the acquired data. If it is not stable, repeat the execution to obtain data of at least one vital sign through the sensor attachment provided on the patient's body, and then determine whether the vital sign data is stable. Stability in this embodiment may refer to: continuously acquiring data corresponding to at least one vital sign for a period of time. Of course, in this embodiment, the data used by the monitoring device to automatically determine whether the detected vital signs data is stable may be valid data.

The monitoring equipment is usually set with a fixed sampling frequency. In general, the monitoring equipment will obtain multiple sampling points during the monitoring of the patient, that is, the effective data of the vital signs corresponding to the multiple times are obtained. For fixed patients In general, the standard data of vital signs does not change much in a long period of time (such as 10 years). Therefore, it is recommended to frequently calculate the alarm limit of the same patient during the monitoring process in days. The value will increase the calculation processing load of the monitoring device, which is undoubtedly a waste of computing resources for the monitoring device. Therefore, in actual use, the monitoring device may only perform the steps of any embodiment of the alarm limit setting method provided by the present invention once when the patient replacement possible information is detected.

Step 300: Calculate the recommended value of the alarm limit corresponding to the at least one vital sign according to the acquired effective data of the at least one vital sign.

When the monitoring device detects valid data of vital signs, the monitoring device may calculate the recommended value of the alarm limit according to the preset algorithm according to the detected valid data of vital signs.

Step 400: Set the alarm limit of at least one vital sign according to the recommended value of the alarm limit.

After calculating the recommended alarm limit value, the monitoring device may set the alarm limit according to the calculated recommended alarm limit value.

In the embodiment of the present invention, when the medical staff sets the sensor on the body of the patient, the monitoring device can detect the valid data of the patient's vital signs through the sensor, and when the monitoring device detects that the connection relationship between the patient and the monitoring device changes The monitoring device can determine whether the valid data of the detected vital signs is stable, and then it can automatically calculate the recommended value of the alarm limit based on the valid data of the obtained vital signs, and set the alarm limit according to the calculation result, because After the medical staff connects the monitoring equipment to the patient, there is no need for the medical staff to manually set the alarm limit for the patient, thus avoiding the situation that the alarm limit is not set for the patient due to human error, which is helpful to reduce waste of medical resources or delay the disease Case.

The rationality of the alarm limit is very important for the recovery of the patient. Therefore, the automatic setting of the alarm limit is best to include the judgment made by medical staff based on experience, so as to avoid the medical staff forgetting to manually set the alarm limit, but also improve The rationality of the alarm limit setting. Please refer to FIG. 3, which is a schematic diagram of another embodiment of the method for setting the alarm limit of the monitoring device of the present invention. Based on the embodiment corresponding to FIG. 2, after step 300, the method for setting the alarm limit further includes:

Step 500: Output request information about setting the alarm limit;

After calculating the recommended value of the alarm limit, the monitoring device can output the request information about setting the alarm limit to prompt the medical staff that the monitoring device has automatically calculated the recommended value of the alarm limit, and ask the medical staff whether to allow the calculated recommendation The value sets the alarm limit.

Step 600: Determine whether feedback information of permission setting of the request information is received, if yes, perform step 400, and if no, perform step 700;

After the monitoring device outputs the request information about setting the alarm limit, it can be judged whether the feedback information of the permission setting of the request information is received. If it is received, step 300 is executed. For details, please refer to the embodiment corresponding to FIG. Repeat; if it is not received, for example, the feedback message indicates that it refuses to set the alarm limit according to the recommended value, step 700 may be performed.

Step 700: Perform other operations.

If the monitoring device determines that it has received the permission setting feedback information for the request information, the monitoring device may perform operations other than step 300, such as setting the alarm limit setting value to the default value of the pre-stored alarm limit value, or outputting an alarm The manual input interface of the limit value sets the alarm limit value according to the value input by the medical personnel.

Regarding the alarm limit setting method embodiment, the following provides two methods for judging whether the valid data of the detected vital signs is stable, mainly by determining whether the valid data corresponding to the vital signs for a period of time is continuously obtained Whether the valid data is stable. The detailed steps are as follows:

Please refer to FIG. 4, when it is detected that the connection relationship between the patient and the monitoring device changes in the above steps, data of at least one vital sign is obtained through a sensor attachment provided on the patient’s body, which is used to determine whether a segment is continuously obtained The process of valid data corresponding to at least one vital sign within a period of time may be achieved by the following detailed steps, or the above process of determining valid data corresponding to at least one vital sign continuously for a period of time may also be determined by the following steps:

101a. When a change in the connection between the patient and the monitoring device is detected, start the timer;

The monitoring device can be turned on when the monitoring device detects a change in the connection between the patient and the monitoring device, such as when the monitoring device is turned on to start the system, or when a sensor that has a signal connection with the monitoring device is connected to the patient's body. Timer, use the timer to record the duration.

102a. When the duration recorded by the timer reaches a preset duration, the monitoring device has continuously obtained valid data corresponding to at least one vital sign, and then it is determined that the valid data of the vital sign is stable.

Whether it is the fluctuation of the effective data of the vital signs caused by the equipment or the fluctuation of the effective data of the vital signs caused by the change of the patient's movement state, this fluctuation is temporary, and this fluctuation will generally gradually weaken over time. The effective data of vital signs tends to be stable. Therefore, when the duration recorded by the timer reaches the preset duration, the monitoring device can determine that the valid data of vital signs is stable. Understandably, when the time recorded by the timer does not reach the preset time, the monitoring device may determine that the valid data of the vital signs is not stable.

Regarding the preset duration, it can be preset by the manufacturer, or can be customized by the medical staff according to experience. Here, the setting method of the preset duration is limited.

Please refer to FIG. 5, when it is detected that the connection between the patient and the monitoring device changes in the above steps, data of at least one vital sign is obtained through a sensor attachment provided on the patient’s body, which is used to determine whether a segment is continuously obtained The process of valid data corresponding to at least one vital sign within a period of time may also be implemented using the following refinement steps, or the above process of determining valid data corresponding to at least one vital sign continuously for a period of time may also be determined using the following steps :

101b. When it is detected that the connection relationship between the patient and the monitoring device changes _, obtain valid data corresponding to at least one vital sign, and calculate stable parameters of the valid data of the acquired vital signs;

When it is detected that the connection relationship between the patient and the monitoring device changes, the monitoring device can calculate the stability parameters of the effective data of the vital signs, and the data stability parameters are used to evaluate the stability of the data. The stability of the data is the analysis result of multiple data from a statistical point of view. Therefore, to calculate the stability parameters of the effective data of vital signs, you need to first obtain the statistical sample set composed of the latest multiple data of vital signs, and then pass the statistical sample The statistical analysis of the centralized data can calculate the stable parameters of the effective data of the vital signs. The monitoring device usually has a fixed sampling frequency, and the monitoring device will obtain the current data of vital signs every fixed period of time, and store the obtained current data to obtain historical data records of vital signs. The monitoring device can select the latest preset number of historical data from the vital signs historical data records or the historical data acquired within the latest preset duration to add to the statistical sample set, and then can calculate the stable parameters of the data in the statistical sample set.

Various methods can be used to calculate the stability parameters of the data. For example, the stability parameters of the data can refer to the variance or standard deviation of the data. The monitoring device can calculate the variance or standard deviation of the data in the statistical sample set. Both the variance and the standard deviation can reflect a The degree of dispersion of the data set is commonly used to evaluate the stability of the data. The smaller the variance or standard deviation of the data in the statistical sample set, the higher the stability of the data and the more stable the data. On the contrary, the lower the stability of the data, the more the data unstable.

102b. Determine whether the calculation result of the stability parameter is better than the threshold of the stability parameter. When it is determined that the calculation result of the stability parameter is better than the threshold of the stability parameter, step 103b is performed. On the contrary, if the calculation result of the stability parameter is not better than the threshold of the stability parameter, then Go to step 104b;

The monitoring device can preset the stability parameter threshold, and the preset stability parameter threshold can be set by factory default or input by the medical personnel. If the larger the value of the stability parameter, the higher the stability. Then, when the calculation result of the stability parameter is greater than the threshold of the stability parameter, the monitoring device can determine that the stability is higher than the stability threshold, which means that the calculation result of the stability parameter is better than Stability parameter threshold. When the calculation result of the stability parameter is less than the stability parameter threshold, the monitoring device may determine that the stability is lower than the stability threshold, which means that the calculation result of the stability parameter is inferior to the stability parameter threshold. If the larger the value of the stability parameter, the lower the stability, then, when the calculation result of the stability parameter is less than the threshold of the stability parameter, the monitoring device can determine that the stability is higher than the stability threshold, which means that the calculation result of the stability parameter is better than Stability parameter threshold. When the calculation result of the stability parameter is greater than the stability parameter threshold, the monitoring device may determine that the stability is lower than the stability threshold, which means that the calculation result of the stability parameter is inferior to the stability parameter threshold.

103b. The effective data of the vital signs determined by the monitoring equipment is stable;

If the monitoring device determines that the effective data of the vital signs is stable, the monitoring device may trigger the execution of the above step 300, that is, the monitoring device triggers execution of calculating the recommended value of the alarm limit corresponding to the vital signs based on the acquired effective data of the vital signs step.

104b. The valid data for determining vital signs is not stable.

Compared with the above two methods for judging whether the effective data of vital signs is stable, the advantage of the method corresponding to FIG. 4 for judging whether the effective data of vital signs is stable is that the amount of calculation is small, and the corresponding method for judging whether the effective data of vital signs is stable The advantage of the method is that the judgment result is more accurate, and it can be selected according to needs in actual use.

Regarding step 300 in the embodiment of the method for setting an alarm limit, after obtaining the effective data of the vital signs of the patient, the recommended value of the alarm limit may be calculated based on the obtained effective data of the vital signs. The recommended value of the alarm limit is generally It is positively correlated with the effective data of vital signs. Taking the recommended value of the alarm limit calculated by the monitoring device based on the heart rate data as an example, the higher the patient's heart rate, the larger the recommended limit value for the heart rate alarm limit set for the patient. The lower the heart rate of, the smaller the recommended value of the alarm limit for the heart rate set. The monitoring device calculates the recommended value of the alarm limit based on the acquired effective data of vital signs according to a preset algorithm. The preset algorithm may be an algorithm pre-stored in the monitoring device or a stored algorithm edited by medical personnel. Be specific. As an example, taking the recommended value of the alarm limit for calculating the heart rate as an example, the preset algorithm may be: the recommended value of the upper limit of the heart rate alarm = effective data of vital signs * 1.25, the recommended value of the lower limit of the heart rate alarm = effective of vital signs Data *0.8. Assuming that the acquired heart rate (HR/PR) data is 80 bpm, the recommended value of the heart rate alarm limit may be: the upper limit recommended value = 100 bpm, and the lower limit recommended value = 64 bpm. In step 200, the effective data of the vital signs used to calculate the recommended value of the alarm limit may be the effective data of the vital signs obtained most recently, or a plurality of data statistics based on the vital signs obtained recently The stable value of the obtained vital signs can be the mean, median or median of multiple data.

Regarding step 300 in the embodiment of the method for setting the alarm limit, the alarm limit is set according to the recommended value of the alarm limit, and the setting value of the alarm limit can be directly set to the recommended value, then when the vital signs corresponding to the alarm limit When the effective data exceeds the recommended value, the monitoring device starts an alarm; or, the setting value of the alarm limit may not be set to the recommended value, for example, because the data of human vital signs in a steady state generally does not exceed a certain limit Value, therefore, the recommended value of the alarm limit can be compared with the limit value of the pre-stored vital signs. If the recommended value of the alarm limit exceeds the limit value of the pre-stored vital signs, the setting value of the alarm limit can be set to life For the limit value of signs, if the recommended value of the alarm limit does not exceed the pre-stored limit value of vital signs, the setting value of the alarm limit can be set as the recommended value.

Therefore, in step 300, after obtaining the effective data of the vital signs of the patient, the recommended value of the alarm limit may be calculated based on the obtained effective data of the vital signs, and the recommended value of the alarm limit is generally the same as the effective data of the vital signs Positive correlation, that is, the default alarm limit of the relevant vital signs or the original alarm limit multiplied by the preset threshold is equal to the recommended value of the alarm limit.

Regarding step 400 in the embodiment of the method for setting the alarm limit, that is, the monitoring device outputs request information about setting the alarm limit, which is described in detail below:

The monitoring device is usually connected to the bedside display device, and the monitoring interface can be displayed on the bedside display device in real time to facilitate the bedside user, such as medical staff, the patient himself or the patient's family members, to view the patient through the monitoring interface displayed on the bedside display device Effective data of vital signs of the patient, and timely understand the patient's condition. The monitoring device outputs the request information about setting the alarm limit. Specifically, it may be a display interface displaying the request information about setting the alarm limit on the bedside display device. Preferably, in order to reduce the influence of the request information on the display of the monitoring interface, the monitoring device displays the request information about setting the alarm limit on the bedside display device. Specifically, the monitoring information can be displayed on the bedside display device in the form of a floating window. The request information for setting the alarm limit is displayed on the display interface.

In order to facilitate medical staff to remotely check the patient's condition, the monitoring device can also output the request information about setting the alarm limit by sending the request information about setting the alarm limit to other terminal devices other than the monitoring device, so that other The terminal device displays the display interface of the request information. The terminals other than the monitoring equipment may refer to the computer equipment or the medical tablet computer of the nurse station or the central station, and the medical personnel can view the display interface of the received request information through the remote computer equipment or the medical tablet computer. The request information may also include the patient's bed information, so that the medical staff can determine the location of the patient and go to check it in time.

Or, the monitoring device outputs the request information about setting the alarm limit, or it may be a display interface that displays the request information about setting the alarm limit on the bedside display device, and also sends the request information about setting the alarm limit to Other terminal devices other than the monitoring device can display the display interface requesting information to the bedside user and the remote user at the same time.

The monitoring device can display the request information displayed on the bedside display device or the request information displayed by other terminal devices. The display interface can have many forms. The following describes the display interface of the request information for setting the alarm limit:

Please refer to FIG. 6, which is a schematic diagram of a display interface 501 for outputting request information about setting an alarm limit. The display interface 501 may include a prompt area 502 and an option area 503, and the option area includes options representing allowable settings and options for denying settings For example, the content displayed in the prompt area 502 may be “Allow automatic setting of alarm limits?”, and the option area 503 may include two options of “allow” and “deny”.

Please refer to FIG. 7, which is a schematic diagram of another display interface 601 that outputs the requested information about setting the alarm limit. The prompt area 602 of the display interface 601 includes the alarm limit automatic setting information 6021 for one or more vital signs. The warning sign automatic setting information of the signs may include the recommended value of the vital sign warning limit and the default value of the vital sign warning limit. Preferably, in order to more vividly compare the alarm limit before modification and the alarm limit after modification, the automatic setting of the alarm limit for each vital sign may include the vital sign with the recommended value as the first interval distribution map 6022 The second interval distribution map 6023 with the default values of the vital signs and the vital signs. Specifically, the vital signs are divided into normal intervals and alarm intervals by the recommended value, and a first interval distribution map 6022 is obtained, and the default values of the vital signs are divided into normal intervals and alarm intervals by the alarm limit value, and a second interval distribution map 6023 is obtained. The first interval distribution map 6022 and the second interval distribution map 6023 each include a normal interval and an alarm interval. If it is an alarm interval, the alarm interval can be further divided according to the alarm level. For example, the alarm interval can be divided into an intermediate alarm interval and an advanced alarm interval. Interval. Preferably, the type identifiers of the normal interval and the alarm interval are different, and the type identifiers of the same type intervals in the first interval distribution map and the second interval distribution map are the same, so that the medical staff can distribute the first interval distribution map 6022 and the second interval Figure 6023 compares the vertical and horizontal directions. The category identifier used for distinguishing may be the color or pattern filled in the interval. As shown in Figure 7, each section is represented by a rectangle. It is assumed that the normal section is a rectangle filled with black dots, the intermediate-level alarm section is a rectangle filled with horizontal line segments, and the high-level alarm section is a rectangle filled with diagonal line segments. Taking heart rate as an example, assuming that there are two recommended upper limits of heart rate alarms, respectively 100bmp and 160bmp, and two recommended lower limits of heart rate alarms, respectively 64bmp and 35bmp, then the first interval distribution diagram of heart rate 6022 includes Three types of intervals, the normal interval is (64,100), and the black dots are used as the category identification. When the patient's heart rate is within (64,100), the monitoring device alarm will not be triggered; the intermediate alarm interval is (100,160) ) Or (35,64), with the filled horizontal line as the category identification, when the patient's heart rate is within the range of (100,160), or within the range of (35,64), the monitoring device is triggered to perform an intermediate alarm; the advanced alarm interval The range is greater than 160 or less than 35, and the filled diagonal line is used as the category identification. When the patient's heart rate is greater than 160bmp or less than 35bmp, the monitoring device is triggered to perform an advanced alarm. Assuming that there are two default upper limits for heart rate alarms, 120bmp and 160bmp, respectively, and two recommended values for lower limit heart rate alarms, respectively 50bmp and 35bmp, then the second interval distribution map for heart rate 6023 includes three categories of intervals The ranges of the three intervals are not described here in detail, please refer to Figure 6.

Continuing to refer to FIG. 7, the display interface 601 may include a total option area 6032. Preferably, the alarm limit automatic setting information 6021 for each vital sign may correspondingly set a sub-option area 6031. By operating the total option area 6032, the medical staff can perform corresponding operations on all the alarm limit automatic setting information 6021 in the display interface 601 at the same time. By operating the sub-option area 6031 corresponding to a certain vital sign, medical staff can only automatically set the alarm limit information of this vital sign to perform corresponding operations, for example, when the medical staff allows the alarm limit of the heart rate according to their recommendations If you want to set the value, but reject the alarm limit of SpO2 (SpO2) according to its recommended value, you can select "Allow" in the sub-option area 6031 corresponding to the heart rate, and the sub-option corresponding to the blood oxygen saturation Select "Reject" in the area 6031. It can be seen that the sub-option area 6031 can facilitate medical staff to automatically process the information 6021 for each alarm limit. When the medical staff wants to process the alarm limit automatic setting information 6021 for all vital signs in a unified manner, the medical staff can operate the total option area 6032, which is convenient and fast. In actual use, the option information in the display interface 601 may include at least one of a sub-option area 6031 and a total option area 6032.

When it is desired to display the alarm limit automatic setting information 6021 of multiple vital signs through the display interface 601, due to the limited size of the display interface 601, in order to improve the clarity of the display of the alarm limit automatic setting information 6021 of each vital sign, the display interface 601 can display the alarm limit automatically setting information 6021 for multiple vital signs by sliding or turning pages. Please refer to FIG. 7, taking the sliding display mode of the display interface 601 as an example, the display interface 601 currently includes alarm limit automatic setting information 6021 for three vital signs, namely HR/PR, SpO2 and NIBP-S, when received When the user slides the instruction, for example, the user performs a sliding operation in the direction of the arrow through the touch screen or the mouse, the monitoring device updates the display content in the display interface 601. Please refer to FIG. 8 for the updated display interface 601, including three lives The alarm limit value of signs is automatically set to information 6021, which are SpO2, NIBP-S and NIBP-D, respectively.

Regarding step 600 in the embodiment of the method for setting the alarm limit, that is, the monitoring device judges whether feedback information of permission setting of the request information is received, the following describes it in detail:

If the monitoring device displays the request information about setting the alarm limit on the bedside display device, the medical staff can select the option that allows the setting or the option that the setting is rejected through the input device of the monitoring device, such as a keyboard, mouse, or touch screen. When the monitoring device receives the medical staff's selection information on the options that are allowed to be set on the display interface, the monitoring device can determine that it has received the feedback information about the permission setting of the request information; when the monitoring device receives the medical staff's rejection of the setting on the display interface When the selection information of the option is selected, the monitoring device may determine that feedback information of permission setting of the request information is not received.

If the monitoring device sends the request information about setting the alarm limit to other terminals other than the monitoring device, the medical staff can give instructions to allow or reject the setting through other terminals. Other terminals package the instructions given by the medical staff as feedback information. When the monitoring device receives the feedback information for the request information, it can analyze the content of the feedback information. If the analysis result indicates that the alarm limit value is allowed to be set according to the recommended value of the alarm limit value, then the received information for the request information can be determined The feedback information is the information allowed to be set. If the analysis result indicates that the alarm limit is not set according to the recommended value of the alarm limit, it can be determined that the received feedback information for the requested information is not the information allowed to be set.
