Description

Technical Field

[0001] This application relates to the technical fields of data processing and status detection, and particularly relates to a user status warning method and related device. Background Art

[0002] Congenital heart disease (hereinafter referred to as CHD) is the most common birth defect and one of the main causes of neonatal death, accounting for about 90%. Children with CHD can survive into adolescence and adulthood through surgical correction. However, during the rehabilitation process, postoperative children still have varying degrees of heart function insufficiency, physical development retardation, and neuropsychological development retardation. According to the "Chinese Guidelines for Cardiac Rehabilitation and Secondary Prevention", for children with simple CHD after surgery, it is recommended that they participate in regular exercises (such as brisk walking, climbing stairs, doing housework, etc.); for infants after surgery, limb and trunk exercise therapy can be carried out 5 days after surgery to improve the gross motor function of the children. Some studies have pointed out that aerobic exercise training under monitoring can significantly improve the cardiopulmonary function of children. Although various guidelines and literatures have confirmed that activities and exercises are beneficial to cardiac rehabilitation, parents' reports indicate that the daily activity time and intensity of postoperative children do not meet the standards due to various restrictions. In addition, the convenience and safety of postoperative wound care are also important considerations.

[0003] Children with CHD need to closely monitor cardiopulmonary function, etc. after surgery. Currently, most children's hospital gowns are scaled-down versions of adult hospital gowns. For children with CHD after surgery, manual monitoring is usually used, resulting in low timeliness and reliability in monitoring children with CHD after surgery. Summary of the Invention

[0077] Referring to "embodiment" in this application means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0078] To better understand a method for warning the status of industrial users provided by the embodiments of the present application, a multifunctional postoperative nursing gown for children with congenital heart disease applying the method for warning the status of application users will be introduced first. The multifunctional postoperative nursing gown for children with congenital heart disease includes a front garment body, a back garment body, sleeves, and a monitoring system. The front garment body is connected to the back garment body and the sleeves, and the monitoring system is arranged on the back garment body. Specifically, the garment body includes a front garment body, a back garment body, and sleeves. An opening is provided in the middle of the front garment body, and a magic tape is arranged at the opening. The front garment body is movably provided with a wound protection patch according to the position of the wound. The wound protection patch includes an inner layer and a surface layer of the wound protection patch. A magic tape is arranged between the inner layer and the surface layer of the wound protection patch, and a magic tape is arranged on the inner layer of the wound protection patch to be connected to the front garment body. A detachable waterproof covering layer is arranged at the neck opening of the front garment body of the hospital gown. The thickness or density of the moisture-absorbing material is increased in the areas of the back, chest, and armpits where sweating is easy to promote air circulation and sweat evaporation. Breathable mesh eyes are arranged on both sides of the waist to promote air circulation and sweat evaporation. A storage bag is arranged on the outer side of the left sleeve opening for storing a finger clip pulse oximeter.

[0079] The monitoring system includes a respiratory rate detector, an electrocardiogram sensor, a finger clip pulse oximeter, a control circuit board, a power supply, and a buzzer. An adjustable elastic band is arranged on the left chest of the front garment body of the nursing gown, with a respiratory rate detector and an electrocardiogram flexible electrode patch built in. By adjusting the elastic band, it is ensured to fit the body of the target user. The lower part of the back garment body is equipped with a control circuit board. A rechargeable lithium battery and a waterproof charging interface are fixedly installed below the control circuit board. A data acquisition module is fixedly installed on the right side of the control circuit board to receive and process data from the respiratory rate sensor detector, the finger clip pulse oximeter, and the electrocardiogram sensor. A data storage module is fixedly installed beside the data acquisition module to save the monitoring data for a period of time. A data analysis module is fixedly installed below the data acquisition module to analyze the cardiopulmonary function status using a built-in algorithm and generate a report. A data transmission module is fixedly installed beside the data acquisition module to transmit the data to the guardian's mobile device via Bluetooth or Wi-Fi. A buzzer and an integrated alarm system are fixedly installed on the right side of the charging interface. When the monitored vital signs exceed the preset normal range, an alarm is issued through sound. The abnormal data can also be sent to the guardian's mobile device via a wireless network.

[0080] When in specific use, when the target user undergoes exercise rehabilitation after congenital heart disease surgery, adjust the elastic band inside the nursing suit to a suitable position so that the respiratory rate detector and the electrocardiogram flexible electrode are attached to the target user's body. Take out the finger clip pulse oximeter from the storage bag on the outer side of the cuff and clip it on the index finger of the target user, and place the wound protection patch on the wound. When the target user starts exercising, various sensors can transmit the target user's heart rate, electrocardiogram, respiratory rate, and blood oxygen saturation to the control circuit board in real time. Through data collection and analysis, the cardiopulmonary condition of the target user during exercise can be obtained. When the vital signs monitored by the alarm system exceed the preset normal range, an alarm will be issued through the buzzer. At the same time, the cardiopulmonary detection data of the target user during exercise will also be transmitted to the parent's mobile device. The main component of the nursing suit is a highly absorbent fiber material. The thickness of the moisture-absorbing material is increased at the parts where sweating is more, such as the armpits, chest, and back, so as to effectively absorb sweat and keep dry. Ventilation meshes are provided on both sides of the waist to promote air circulation and sweat evaporation. Among them, the target user can be a congenital heart disease child, etc.

[0081] Therefore, the multifunctional postoperative care for children with congenital heart disease has the following advantages:

[0082] 1. The material of the nursing suit is selected as a highly absorbent fiber material. The thickness of the moisture-absorbing material is increased at the parts where sweating is more, and ventilation meshes are provided on both sides of the waist, which can effectively absorb sweat, keep the skin dry, and accelerate air circulation and sweat evaporation;

[0083] 2. There are a respiratory rate detector and an electrocardiogram flexible electrode on the elastic band on the left chest inside the nursing suit, which are used to detect the child's respiratory rate and electrocardiogram; a storage bag is provided on the outer side of the left cuff, and a finger clip pulse oximeter is installed inside to detect the child's oxygen saturation;

[0084] 3. A wound protection patch is movably arranged inside the nursing suit, which is convenient for replacing the wound dressing and preventing wound infection.

[0085] 4. The alarm system at the lower part of the back body of the nursing suit can monitor the vital signs. When it exceeds the preset normal range, an alarm will be issued through the buzzer.

[0086] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a user status warning method provided by an embodiment of this application. As Figure 1 shown, this method is applied to the multifunctional postoperative nursing suit for children with congenital heart disease, and this method includes:

[0087] 101. Obtain the physical sign status information of the target user, where the physical sign status information includes respiratory rate, first electrocardiogram signal, and blood oxygen information.

[0088] Among them, the respiratory rate can be obtained through the respiratory rate detector in the multifunctional postoperative care clothing for children with congenital heart disease, the first electrocardiogram signal can be obtained through the electrocardiogram sensor, and the blood oxygen information can be obtained through the finger clip pulse oximeter.

[0089] 102. Determine the target status information of the target user according to the respiratory rate, the first electrocardiogram signal, and the blood oxygen information.

[0090] Among them, the corresponding reference status information can be determined according to the respiratory rate, the first electrocardiogram signal, and the blood oxygen information respectively, and then the multiple reference status information is fused to obtain the target status information.

[0091] 103. If the target status information is abnormal status information, generate a warning message.

[0092] When generating a warning message, the warning message can be obtained by looking up a table according to the abnormal status information by means of a look-up table method, etc. Since the corresponding abnormal information is different when different target status information is abnormal information, the warning message can be determined by the look-up table method. The warning message can indicate that the target user is in an abnormal state.

[0093] 104. Send the warning message to the electronic device of the guardian of the target user to instruct the electronic device to perform warning processing.

[0094] The warning message can be sent to the electronic device of the guardian of the target user through Bluetooth or Wi-Fi. This electronic device can be, for example, a mobile phone, a computer, etc. After receiving the warning message, the electronic device can emit a warning prompt sound for warning processing. Of course, it can also be through other means for warning processing. This is only for illustrative purposes and is not specifically limited.

[0095] In this example, by obtaining the physical sign status information of the target user, the physical sign status information includes the respiratory rate, the first electrocardiogram signal, and the blood oxygen information, determining the target status information of the target user according to the respiratory rate, the first electrocardiogram signal, and the blood oxygen information, if the target status information is abnormal status information, generating a warning message, and sending the warning message to the electronic device of the guardian of the target user to instruct the electronic device to perform warning processing. Therefore, it is possible to collect the status information of the user in real time and perform status discrimination, and perform alarm processing when in an abnormal state, thereby improving the timeliness and reliability of the alarm.

[0096] In a possible implementation manner, a method for determining the target status information of the target user according to the respiratory rate, the first electrocardiogram signal, and the blood oxygen information includes:

[0097] A1. Determine the first reference status information according to the first respiratory rate;

[0098] A2. Optimize the first electrocardiogram signal to obtain a second electrocardiogram signal;

[0099] A3. Determine the second reference state information according to the second electrocardiogram signal;

[0100] A4. Determine the third reference state information according to the blood oxygen information;

[0101] A5. Perform fusion processing on the first reference state information, the second reference state information, and the third reference state information to obtain the target state information.

[0102] Among them, different breathing frequency intervals can have their corresponding state information, so that the breathing frequency interval where the first breathing frequency is located can be determined, and then the first reference state information can be determined through this breathing frequency interval. The first reference state information can include a normal state, a low-risk state, a medium-risk state, and a high-risk state. The normal state, the low-risk state, the medium-risk state, and the high-risk state have their corresponding breathing frequency intervals, and this breathing frequency interval can be set by combining the historical data breathing frequency of the target user with empirical values. The method for determining the third reference state information according to the blood oxygen information can refer to the method for determining the first reference state information, which will not be elaborated here.

[0103] The method for optimizing the first electrocardiogram signal to obtain a second electrocardiogram signal can be to perform segmentation processing on the first electrocardiogram signal to obtain multiple heartbeat signals, and perform filtering, positioning, and then fusion processing on the multiple heartbeat signals to obtain the second electrocardiogram signal. Thus, fusion processing can be performed by combining the characteristics of multiple heartbeat signals to improve the stability and accuracy of the obtained second electrocardiogram signal, so that the second electrocardiogram signal is closer to the real data of the target user.

[0104] Different second electrocardiogram signals will reflect different user states. Therefore, the second reference state information can be determined according to this second electrocardiogram signal.

[0105] Finally, perform fusion processing on the first reference state information, the second reference state information, and the third reference state information to obtain the target state information, so as to improve the accuracy when obtaining the target state information.

[0106] In a possible implementation, a method for optimizing the first electrocardiogram signal to obtain a second electrocardiogram signal includes:

[0107] B1. Perform segmentation processing on the first electrocardiogram signal to obtain m first heartbeat signals;

[0108] B2. Perform filtering processing on the m first heartbeat signals to obtain m second heartbeat signals;

[0109] B3. Perform R-wave positioning processing on the m second heartbeat signals to obtain m R-wave position information;

[0110] B4. Use the m R-wave position information to perform fusion processing on the m second heartbeat signals to obtain a second electrocardiogram signal.

[0111] Among them, the first electrocardiogram signal can be segmented using the forward voltage data points, so that m first heartbeat signals can be segmented. A heartbeat signal can be the electrocardiogram signal between the peak of an R wave as the starting point and the peak of an adjacent R wave as the ending point.

[0112] The m first heartbeat signals can be filtered using a general filtering method to obtain m second heartbeat signals.

[0113] A general R-wave positioning method can be used for positioning processing to obtain R-wave position information.

[0114] After obtaining the m R-wave position information, the second heartbeat signals can be fused based on the m R-wave position information to obtain a second electrocardiogram signal. When performing fusion processing, the fusion positioning area of the second heartbeat signals can be determined, and the final fusion positioning point can be determined in the fusion positioning area. After alignment of the fusion positioning point, fusion processing is performed to obtain a second electrocardiogram signal. Since there may be fluctuations in the signal amplitude around the R-wave position information, when directly using the R-wave position information for fusion, it may not be the best fusion point, which may lead to a situation where although the second electrocardiogram signal obtained after fusion has the comprehensive characteristics of multiple signals, due to the existence of non-optimal fusion points, it is also possible that the information carried by the second electrocardiogram signal is deviated, reducing the accuracy in subsequent processing. At the same time, since the acquisition device is designed on a wearable device, which is a lightweight device with limited computing power, using the R-wave position information for fusion during fusion can reduce the amount of computation, but using the best fusion point for fusion can improve the accuracy while taking into account the computing power, greatly improving the practicality of the product.

[0115] In a possible implementation, a method for using m R-wave position information to perform fusion processing on m second heartbeat signals to obtain a second electrocardiogram signal includes:

[0116] C1. Extract a first reference fusion positioning area from the corresponding second heartbeat signal according to the first R-wave position information, where the first R-wave position information is any one of the m R-wave position information;

[0117] C2. Determine k reference fusion positioning points from within the first reference fusion positioning area;

[0118] C3. Determine the target fusion localization point of the second heartbeat signal corresponding to the first R-wave position information based on the positive voltage data of the k reference fusion localization points and the position information of the k reference fusion localization points.

[0119] C4. Repeat the method of extracting the first reference fusion localization region from the corresponding second heartbeat signal according to the first R-wave position information to determining the target fusion localization point based on the positive voltage data of the k reference fusion localization points and the position information of the k reference fusion localization points until the target fusion localization points corresponding to m second heartbeat signals are obtained.

[0120] C5. Align and then fuse the m second heartbeat signals according to the target fusion localization points corresponding to the m second heartbeat signals to obtain the second electrocardiogram signal.

[0121] Among them, the region corresponding to the heartbeat signal intercepted from the corresponding second heartbeat signal with the signal point corresponding to the first R-wave position information as the center and a preset length as the radius can be used as the first reference fusion localization region. The preset length radius is set by empirical values or historical data.

[0122] The amplitude of the electrocardiogram signal within the first reference fusion localization region can be obtained, and then the mean value of the amplitudes can be processed to obtain the amplitude mean value. Based on this mean value, k reference fusion localization points are determined within the first reference fusion localization region. Specifically, k signal points greater than this mean value can be obtained and determined as reference fusion localization points, which can be randomly obtained signal points corresponding to the amplitudes greater than this mean value. It should be noted that the k reference fusion localization points include the signal point corresponding to the first R-wave position information.

[0123] The first quantity of the reference fusion localization points on the left side of the signal point corresponding to the first R-wave position information can be extracted, and the second quantity of the reference fusion localization points on the right side of the signal point corresponding to the first R-wave position information can be extracted. The absolute value of the difference between the first quantity and the second quantity is obtained to get the third quantity. If the third quantity is less than the preset threshold, the signal point corresponding to the first R-wave position information is determined as the target fusion localization point. If the third quantity is greater than the preset threshold, the maximum value of the first quantity and the second quantity is extracted to obtain the target quantity value; according to this target quantity value, the signal point closest to the signal point corresponding to the first R-wave position information among the reference fusion points corresponding to the target quantity value is determined, and the midpoint between this signal point and the signal point corresponding to the first R-wave position information (this midpoint is the point in the second heartbeat signal corresponding to the first R-wave position information) is determined as the target fusion localization point. Therefore, the final target fusion localization point can be determined by combining the regional characteristics and the signal point corresponding to the first R-wave position information, reducing the adverse effects caused by signal fluctuations and improving the accuracy when determining the target fusion localization point.

[0124] In a possible implementation, a method for fusing the first reference state information, the second reference state information, and the third reference state information to obtain the target state information includes:

[0125] D1. Obtain the weight information corresponding to the first reference state information to obtain the first weight information;

[0126] D2. Obtain the weight information corresponding to the second reference state information to obtain the second weight information;

[0127] D3. Obtain the weight information corresponding to the third reference state information to obtain the third weight information;

[0128] D4. Perform a weighted operation on the first reference state information, the second reference state information, and the third reference state information using the first weight information, the second weight information, and the third weight information to obtain the first state information;

[0129] D5. Obtain the first state correction value corresponding to the first reference state information and obtain the second state correction value corresponding to the second reference state information;

[0130] D6. Perform a fusion process on the first state correction value and the second state correction value to obtain the target state correction value;

[0131] D7. Perform a correction process on the first state information using the target state correction value to obtain the target state information.

[0132] Among them, different reference state information has its corresponding weight information, so that the first weight information, the second weight information, and the third weight information can be determined. Specifically, the first weight information, the second weight information, and the third weight information can be determined by methods such as a look-up table method. The first reference state information, the second reference state information, and the third reference state information can be represented by corresponding state values, so subsequent weighted operations can be performed.

[0133] A general weighted operation method can be used to perform the weighted operation to obtain the first state information.

[0134] Since the respiratory rate and heart rate are extremely important monitoring indicators when monitoring the target user, a status correction value can be generated for them. For example, the larger the status value corresponding to the first reference status information, the larger the status correction value, and they can exhibit an exponential correspondence, specifically to highlight that after the status value increases, the risk of the target user increases sharply. Thus, the first status correction value can be determined by combining the status value corresponding to the first reference status information, and the second status correction value can be determined by combining the status value corresponding to the second reference status information. The sum of the first status correction value and the second status correction value can be determined as the target status correction value. Finally, the product of the target status correction value and the status value corresponding to the first status information is determined as the status value corresponding to the target status information, improving the accuracy when determining the target status information. The target status information can be characterized by the corresponding status value.
