As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Where there is no conflict, the embodiments and features described herein can be combined with each other.

[0019] To make the technical solutions and advantages of this disclosure clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a more detailed account of this disclosure.

[0020] Figure 1 A flow 100 of one embodiment of the signal control method of this disclosure is shown. For example... Figure 1 As shown, the signal control method of this embodiment may include the following steps:

[0021] Step 101: Acquire the biological signals of the target object in real time.

[0022] In this embodiment, the entity executing the signal control method can acquire the biological signals of the target object in real time through various biological signal acquisition devices. The target object can be a human body or an animal body. Biological signals can include, but are not limited to, electrocardiogram (ECG) signals, blood pressure signals, venous signals, etc. The aforementioned biological signal acquisition devices can include ECG leads, blood pressure monitors, photoelectric sensors, etc.

[0023] Step 102: Analyze the biological signal using the first and second methods to determine whether the target signal has been detected.

[0024] After acquiring the biological signals of the target object, the executing entity can analyze the biological signals using a first method and a second method respectively to confirm whether the target signal has been detected. Here, the sensitivity of the first method is lower than that of the second method, but the accuracy of the first method is higher than that of the second method. That is, the second method detects more target signals than the first method, but the target signals detected by the second method may contain errors. Although the first method detects fewer target signals, the probability of errors in the target signals detected by the first method is lower. The first method and the second method can be algorithms individually or a combination of algorithms. In some specific practices, the first method may include, but is not limited to, the phase space method and the energy operator method, while the second method may include, but is not limited to, the differential algorithm of Pan in classical electrocardiogram detection, deep learning algorithms, and the electrocardiogram vector arc method.

[0025] Specifically, when analyzing biological signals using the first and second methods, each method yields a calculation result for the biological signal. Based on these results, it can be determined whether a target signal has been detected. For example, the calculation result could be a parameter value, and the first method might obtain a first parameter value. If the first parameter value is a first preset value, it can be considered that the target signal has been detected using the first method. Similarly, the second method might obtain a second parameter value. If the second parameter value is a second preset value, it can be considered that the target signal has been detected using the second method.

[0026] The target signal here can be a specific local signal within the aforementioned biological signals, a specific value within the biological signal, or a value with a certain characteristic within the biological signal. For example, if the biological signal is an electrocardiogram (ECG) signal, the target signal can be the R wave. If the biological signal is a blood pressure signal, the target signal can be the trough of low blood pressure.

[0027] Step 103: In response to determining that a target signal has been detected, determine the interval between two adjacent target signals.

[0028] After detecting a target signal, the interval between two adjacent target signals can be determined. Specifically, the time difference between the current time the target signal is detected and the last time it is detected can be used as the interval between two adjacent target signals. Alternatively, after multiple detections of the target signal, the executing entity can calculate the interval by calculating the time difference between the first and last time the target signal is detected, combined with the number of times the target signal is detected. Alternatively, the interval can be updated in real time using the aforementioned average and the time of the real-time detected target signal. For example, if the average is 0.23 seconds, and the time between the latest detected target signal and the last detected target signal is 0.21 seconds, then a weighted value of 0.23 seconds and 0.21 seconds can be calculated, for example, as 0.22 seconds, as the interval.

[0029] Step 104: Predict the triggering time of the control signal based on the interval.

[0030] After determining the interval, the trigger time of the control signal can be further predicted. Specifically, the trigger time can be a preset time point within the interval. For example, if the interval is 0.23 seconds, the trigger time could be at 0.15 seconds. Alternatively, the trigger time of the control signal can be determined based on the occurrence time of a certain signal value in the biosignal within a certain time period of the interval. For example, if the biosignal is a blood pressure signal and the interval is 0.23 seconds, if a minimum blood pressure value is detected within the time period of 0.13 to 0.16 seconds, the trigger time would be 0.02 seconds after the occurrence of the minimum value.

[0031] Step 105: Control the control signal according to the trigger time.

[0032] After determining the trigger time, the control signal can be controlled accordingly. For example, the control signal can be triggered when the trigger time arrives. Alternatively, a countdown can be started based on the trigger time. If preset conditions are met during the countdown, the control signal will be triggered when the trigger time arrives. The control signal can be either an inflation signal or a deflation signal.

[0033] The signal control method provided in the above embodiments of this disclosure analyzes biological signals simultaneously using two methods with different sensitivity and accuracy to determine whether a target signal is detected, and performs signal control based on the target signal, thereby improving the accuracy of signal control.

[0034] See also Figure 2 This illustrates a flow 200 of another embodiment of the signal control method according to the present disclosure. Figure 2 The method shown includes the following steps:

[0035] Step 201: Acquire the first biological signal in real time through the first channel, and acquire the second biological signal in real time through the second channel.

[0036] In this embodiment, the biological signal may include a first biological signal and a second biological signal. The first biological signal and the second biological signal may be of the same type or different types. For example, both the first biological signal and the second biological signal may be electrocardiogram (ECG) signals. Alternatively, the first biological signal may be an ECG signal, and the second biological signal may be a blood pressure signal.

[0037] The executing entity can acquire the aforementioned first and second biological signals through different channels. For example, the first biological signal can be acquired through lead II, and the second biological signal can be acquired through lead V or a blood pressure lead.

[0038] Step 202: Analyze the biological signal using the first and second methods to determine whether the target signal has been detected.

[0039] In this embodiment, since the biological signal includes a first biological signal and a second biological signal, when analyzing the biological signal, the first biological signal can be analyzed using a first method and the second biological signal can be analyzed using a second method. Alternatively, the first and second biological signals can be analyzed simultaneously using both methods. Based on the analysis results, it is determined whether the target signal has been detected.

[0040] Specifically, if either the first method or the second method detects the target signal, it can be considered that the target signal has been detected, and the detection results of the two methods are recorded.

[0041] Here, the sensitivity of the first method is less than that of the second method, and the accuracy of the first method is greater than that of the second method.

[0042] Step 203: In response to the detection of the target signal in the first manner, the first parameter is set to a preset value; the interval between two adjacent target signals is determined based on multiple times when the first parameter is set to the preset value.

[0043] In this embodiment, if a target signal is detected by the first method, the first parameter can be set to a preset value. Here, the first parameter can be denoted as FlagR1. After the target signal is detected, FlagR1 is set to 1. Then, based on the moment when FlagR1 is set to 1, the interval between two adjacent target signals is calculated. It is understood that the preset value can be any pre-set value.

[0044] Step 204: In response to the detection of the target signal by the second method, the second parameter is set to a preset value.

[0045] In this embodiment, if the target signal is detected by the second method, the second parameter can be set to a preset value. Here, the second parameter can be denoted as FlagR2. After the target signal is detected, FlagR2 is set to 1. It is understood that the value set for the second parameter can be the same as or different from the value set for the first parameter. The above preset value is mainly used to confirm whether the target signal has been detected by this method.

[0046] Step 205: Determine the first trigger time of the first control signal and the second trigger time of the second control signal based on the interphase and biological signals.

[0047] In this embodiment, the control signal may include a first control signal and a second control signal. The first control signal can be used to control the inflation of the balloon, and the second control signal can be used to control the inhalation of the balloon.

[0048] After determining the interval between two adjacent target signals, the first trigger time of the first control signal and the second trigger time of the second control signal can be determined by combining the biological signals. Specifically, the position of a specific signal within the biological signal can be determined based on its position within the aforementioned interval. Then, based on the current time and the aforementioned position, the first trigger time of the first control signal is determined. Alternatively, a biological parameter value can be determined first based on the aforementioned interval. Then, based on the correspondence between the biological parameter value and the first and second delays, the first delay corresponding to the first control signal and the second delay corresponding to the second control signal are determined. Finally, the first trigger time is determined based on the occurrence time of the target signal and the first delay. The second trigger time is determined based on the occurrence time of the target signal and the second delay.

[0049] In this embodiment, the first control signal can be triggered at a first triggering time, and the second control signal can be triggered at a second triggering time. Furthermore, the second triggering time is later than the first triggering time. That is, the second control signal is triggered only after the first control signal is triggered. Specifically, regarding the balloon, the balloon's inhalation is further controlled only after the balloon is inflated.

[0050] In some specific implementations, the aforementioned biosignals are electrocardiogram (ECG) signals. The first control signal is used to control balloon inflation, and the second control signal is used to control balloon inhalation. First, the heart rate value can be determined based on the aforementioned intervals. Based on the determined heart rate value, a pre-set mapping table of heart rate values ​​and the first and second delays is consulted to determine the specific first and second delay values. Then, based on the time of R-wave appearance and the aforementioned first delay value, the inflation trigger time is determined. Based on the time of R-wave appearance and the aforementioned second delay value, the inhalation trigger time is determined.

[0051] In some optional implementations of this embodiment, the aforementioned first and second delays may be affected by three factors: device delay, physiological delay (the time difference between the start of cardiac contraction and actual blood ejection), and physical effect delay (the time difference between the start of balloon contraction and the start of cardiac contraction in IABP (Intra-Aortic Balloon Pumping), within which cardiac ejection load reaches its minimum). To accurately determine the aforementioned first and second delays, the device controlling balloon inflation and deflation can be tested multiple times to determine the device delay and physical effect delay. Simultaneously, the physiological delay can be determined based on clinical experience. Finally, a more precise first and second trigger times can be determined.

[0052] Step 206: Based on the trigger time, start a countdown from the current time. If the second parameter is detected to be set to a preset value during the countdown, cancel the triggering of the first control signal and the second control signal.

[0053] If the first and second trigger times are determined, a countdown can be started based on these times. If, during the countdown, the second parameter is detected to be set to a preset value, it indicates that the target signal has been detected by the second method, and the triggering of both the first and second control signals needs to be cancelled.

[0054] In some specific practices, the biosignal is an electrocardiogram (ECG) signal. The first trigger moment is the balloon inflation moment, and the second trigger moment is the balloon inspiration moment. If the target signal, such as an R wave, is detected during the inflation countdown, it indicates that the heart is currently in systole, and balloon inflation is not permitted at this time. Therefore, balloon inflation and inspiration must be canceled.

[0055] In some optional implementations of this embodiment, the first control signal and the second control signal can be canceled by setting the trigger time of the first control signal and the trigger time of the second control signal to initial values.

[0056] The initial value here can be 0, or a pre-set value. Once the trigger time is detected to be set to this value, the first and second control signals will no longer be triggered.

[0057] Step 207: If the second parameter is not detected to be set to a preset value during the countdown, the first control signal is triggered when the countdown ends.

[0058] In this embodiment, if the second parameter is not detected to be set to a preset value during the countdown, the first control signal is triggered when the countdown ends. Specifically, if no R wave is detected during the countdown, it indicates that the heart is currently in diastole, and the balloon can be inflated. Therefore, the first control signal can be triggered when the countdown ends.

[0059] Step 208: After the first control signal is triggered, during the countdown of the second control signal, if the second parameter is detected to be set to a preset value, the second control signal is immediately triggered.

[0060] Because the second triggering time is later than the first triggering time, the second control signal may not have been triggered after the first control signal has been triggered. If the target signal is detected during the countdown of the second control signal after the first control signal has been triggered, the second control signal needs to be triggered. Specifically, if the target signal is detected after the balloon is inflated, it indicates that the heart is currently in systole, and the balloon needs to be inflated immediately; therefore, the second control signal needs to be triggered immediately.

[0061] In some optional implementations of this embodiment, the biological signals of the target object can be acquired multiple times before the first control signal is triggered for the first time. The interval between the acquired biological signals is determined based on the intervals. This improves the accuracy of the intervals, thereby enabling more precise determination of the trigger times of the first and second control signals and achieving more accurate control.

[0062] In some optional implementations of this embodiment, if the second parameter is detected to be set to a preset value during the countdown, the biological signals of the target object need to be acquired multiple times before the first control signal is triggered next time. The interval of the target signal is then re-determined based on the biological signals acquired after the moment the second parameter is set to the preset value. This allows for more precise control of both the first and second control signals.

[0063] In some optional implementations of this embodiment, the parsing result of the first biological signal is used to trigger the first control signal, and the parsing result of the second biological signal is used to trigger the second control signal.

[0064] In this implementation, the first control signal and the second control signal can be controlled separately using biological signals collected from different channels and different trigger sources. This enables separate control of inflation and inhalation, and also improves the accuracy of control.

[0065] In some optional implementations of this embodiment, to further improve the accuracy of control, a first method can be used to simultaneously analyze the first biological signal and the second biological signal. If the analysis results of the two are consistent, both indicating that the target signal has been detected, then it is confirmed that the target signal has been detected through the first method. Similarly, a first method can be used to simultaneously analyze the first biological signal and the second biological signal. If the analysis result of either of them indicates that the target signal has been detected, then it is considered that the target signal has been detected through the second method.

[0066] See also Figure 3 This illustrates a signal processing flowchart in a cardiac application scenario of the above embodiments. Figure 3 The process may include the following stages:

[0067] 1) Detection Phase: At the start of each cycle, the inflation / deflation flag FlagDeflate = 0. Two QRS detection methods are performed simultaneously: one is a highly specific detection method, including but not limited to the phase space method and energy operator method; when an R wave is detected, the detection flag FlagR1 = 1. The other is a highly sensitive detection method, including but not limited to the differential algorithm of Pan in classic ECG detection, deep learning algorithms, and the ECG vector arc method; when an R wave is detected, the detection flag FlagR2 = 1.

[0068] 2) Determine if the R-wave is detected: If the high-specificity detection method detects the R-wave, set the detection flag FlagR1 = 1. If the high-sensitivity detection method detects the R-wave, set the detection flag FlagR2 = 1.

[0069] 3) Update the RR interval: If FlagR1 = 1, update the RR interval, which is the time corresponding to two consecutive FlagR1 = 1. If FlagR1 = 0, proceed directly to step 5).

[0070] 4) Calculate the inflation / deflation trigger countdown: If FlagR1 = 1, then predict the optimal inflation trigger time Timer_I = T1 and the optimal inhalation trigger time Timer_D = T2 based on the RR interval.

[0071] 5) Calculate the inflation / deflation countdown. If Timer_I>0, then Timer_I-- in each cycle; if Timer_D>0, then Timer_D-- in each cycle.

[0072] 6) Inflation trigger: Following step 5), if Timer_I = 0, the inflation countdown ends, and FlagDeflate = 1, inflation is triggered.

[0073] 7) Inhalation trigger: Following step 5), if Timer_D = 0, the inhalation countdown ends, FlagDeflate = -1, and inhalation is triggered.

[0074] 8) Determine if inflation is cancelled: If Timer_I>0 before the inflation countdown ends, and if FlagR2=1, then the inflation trigger and air intake trigger are cancelled, and Timer_I=0, Timer_D=0.

[0075] 9) Pre-inhalation: If Timer_I = 0 and Timer_D > 0, inflation has been triggered but inhalation has not yet started; if FlagR2 = 1, then FlagDeflate = -1, and inhalation is triggered immediately.

[0076] 10) Loop ends: Return to step 1) and start the next loop.

[0077] The signal control method provided in the above embodiments of this disclosure can improve the accuracy of signal control. When applied in the field of electrocardiography, it can ensure highly sensitive balloon inhalation, avoid increased pre-ejection load on the heart, and ensure high-specificity inflation, reducing the risk of erroneous inflation.
