Description

TECHNICAL FIELD

[0001] The present application belongs to the field of equipment detection, and particularly relates to a blood pressure simulator leakage detection method and device, electronic equipment and storage medium. BACKGROUND

[0002] As a key medical measuring instrument, the sealing performance of the gas path system of a non-invasive blood pressure simulator directly affects the accuracy and reliability of blood pressure simulation. The current industry generally adopts the oscillographic method principle, and uses static pressure attenuation as the basis for leakage judgment. This method determines the sealing state by monitoring whether the linear decay rate at a fixed pressure point exceeds the threshold value. However, the existing detection method has the following defects:

[0003] Sensitivity limitation of static detection: The traditional method cannot effectively capture the nonlinear leakage characteristics (such as micro-pore leakage and intermittent leakage under dynamic pressure fluctuation). When the leakage is below the detection threshold, false negatives are easy to occur, causing small leaks to accumulate into systematic errors over a long period of use.

[0004] Misjudgment risk caused by environmental interference: Pressure sensors are susceptible to environmental temperature drift, electromagnetic noise and other interference, producing signal decay characteristics similar to real leakage. Conventional filtering algorithms have insufficient signal-to-noise separation capability in complex noise backgrounds, resulting in a significant increase in false detection rates.

[0005] Low efficiency of high-dimensional signal processing: Conventional wavelet transform processing of high-dimensional pressure signals has a large amount of calculation, making it difficult to dynamically compensate for errors in real time, resulting in low detection sensitivity.

[0050] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0051] In order to improve the sensitivity and accuracy of leak detection in blood pressure simulators, the present invention utilizes the high efficiency and parallel processing capabilities of quantum computing to significantly improve the identification sensitivity of weak leakage signals. It also combines the localization characteristics and multi-scale analysis capabilities of wavelet analysis to accurately extract multi-dimensional leakage characteristics, and integrates the dual indicators of entropy change rate and pressure decay rate to jointly calculate the leakage rate from the time domain (pressure change) and frequency domain (complexity change), significantly improving the robustness of the leakage detection method and having higher sensitivity and accuracy.

[0052] The present invention discloses a blood pressure simulator leak detection method for leak detection of non-invasive blood pressure simulators. This method can be implemented through computer programming as a standalone blood pressure simulator leak detection system. The method can be performed by an electronic device such as a computer, laptop, or tablet computer, or a control chip embedded in an electronic device, but the present invention is not limited to this. It should be noted that this method is not limited to non-invasive blood pressure simulators and can also be used for other medical devices with airway systems, such as ventilators.

[0053] like Figure 1 As shown, an embodiment of the blood pressure simulator leakage detection method includes the following steps:

[0054] Step S100: After the target instrument is inflated to a preset pressure, a pressure signal of the target instrument under static conditions is collected at preset time intervals to obtain a pressure decay signal sequence;

[0055] The target instrument is a non-invasive blood pressure simulator. Static conditions mean the gas circuit system must be completely static, with all inflation and deflation valves closed and any airflow stopped. This means there is no gas flow and no active inflation or deflation operations.

[0056] The preset pressure can be determined according to the actual situation of the target instrument. First, the target instrument is inflated to the preset pressure, and then the pressure signal is collected. When collecting, the collection is carried out according to the preset time interval. In this embodiment, the time interval is preferably 0.1s, and the pressure decay signal sequence is obtained. , .

[0057] Step S200: mapping the pressure signal in the pressure attenuation signal sequence into a quantum state through quantum phase encoding to obtain a pressure signal quantum sequence;

[0058] Quantum phase encoding is a way to store information in the phase part of a quantum state by adjusting the phase modulation factor , can encode different information.

[0059] Specifically, the calculation formula of quantum phase encoding is:

[0060] ;

[0061] wherein, is the quantum state of the pressure signal, is the length of the pressure decay signal sequence, is the th quantum bit ground state, is the imaginary unit, is the phase modulation factor of the th pressure signal in the pressure decay signal sequence, is the index of the pressure signal in the pressure decay signal sequence.

[0062] wherein, the calculation formula is:

[0063] ,

[0064] wherein, is the maximum pressure value in the pressure decay signal sequence, is the minimum pressure value in the pressure decay signal sequence, is the pressure value of the th pressure signal in the pressure decay signal sequence.

[0065] In the pressure decay signal sequence, the pressure values at different times are different, resulting in different values corresponding to them. By continuously calculating the values at different times, the dynamic change information of the pressure decay over time can be encoded. When the non-invasive blood pressure simulator is in normal no-leakage state, small leakage state and significant leakage state, the corresponding pressure decay signal sequence is different, and distribution is also different. Therefore, by extracting and analyzing the features of the encoded pressure signal quantum sequence, the difference can be accurately identified, and the leakage condition of the non-invasive blood pressure simulator can be further judged.

[0066] After quantum phase encoding is completed, the pressure signal quantum sequence is obtained, .

[0067] Step S300: using a hybrid wavelet basis function to perform multi-scale decomposition on the pressure signal quantum sequence, and calculating the decomposition coefficients corresponding to each decomposition scale;

[0068] The hybrid wavelet basis function is a function system formed by combining or fusing different types of wavelet basis functions. It combines the characteristics of multiple wavelet bases to better adapt to the diverse needs of complex signal processing, image analysis and other fields. is an adaptive Haar-Daubechies mixed wavelet basis (a mixture of Haar wavelet basis and Daubechies wavelet basis), satisfying , and the energy is normalized.

[0069] Mixed wavelet basis functions The calculation formula is:

[0070] ;

[0071] in, To decompose the scale, is the translation parameter, is the time variable.

[0072] By changing the decomposition scale The value of can adjust the frequency range of the wavelet basis function, thereby realizing multi-scale analysis of different frequency components of the signal. The value of can make the wavelet basis function move on the time axis, so as to analyze the signal in different time periods. Therefore, the hybrid wavelet basis function has good localization characteristics in both time domain and frequency domain, and can decompose and analyze the signal from multiple scales and angles.

[0073] The decomposition coefficients reflect the projection size of the pressure signal quantum sequence onto the wavelet basis function. Different leakage states produce different projections onto the wavelet basis function. Therefore, the decomposition coefficients can extract key leak-related features from the pressure signal, providing a highly sensitive analytical basis for microleak detection. Because the scale parameter (i.e., decomposition scale) and translation parameter of the wavelet basis function can be varied, the decomposition coefficients can reveal the characteristics of the pressure signal at different scales and time locations.

[0074] Specifically, the calculation formula for the decomposition coefficient corresponding to a certain decomposition scale is:

[0075] ;

[0076] in, Decomposition scale The corresponding decomposition coefficients are, ; is the translation parameter, , used to locate the time domain position of the leakage event; is the wavelet basis function The conjugate transpose of the corresponding quantum state; is the maximum number of decomposition levels, , corresponding to the pressure signal frequency band (0.1~10Hz), is the length of the pressure decay signal sequence; is the index of the pressure signal in the pressure decay signal sequence.

[0077] Step S400: Calculating the quantum Shannon entropy corresponding to each decomposition scale according to the decomposition coefficient corresponding to each decomposition scale;

[0078] Step S500: Based on the quantum Shannon entropy corresponding to all decomposition scales, a quantum annealing algorithm is used to solve the optimal decomposition scale;

[0079] Quantum Shannon entropy measures the uncertainty or complexity of the quantum state corresponding to the pressure signal quantum sequence at a given decomposition scale. By calculating the quantum Shannon entropy at different decomposition scales, a quantum annealing algorithm can be used to find the optimal decomposition scale. The optimal decomposition scale is the one that maximizes the distinction between the normal pressure decay state and the leak pressure state. At this optimal decomposition scale, characteristics such as the quantum Shannon entropy corresponding to the pressure signal quantum sequences in the normal and leak states are clearly distinct, helping to accurately determine whether a leak exists.

[0080] The calculation formula of quantum Shannon entropy is:

[0081] ;

[0082] in, Representative decomposition scale The quantum Shannon entropy under Decomposition scale , translation parameters The corresponding decomposition coefficient.

[0083] The expression for solving the optimal decomposition scale by quantum annealing algorithm is:

[0084] ;

[0085] in, is the optimal decomposition scale, is the regularization coefficient, which can be determined based on experience in combination with actual conditions; Decomposition scale The variance of the lower entropy value reflects the decomposition stability, Decomposition scale Quantum Shannon entropy under .

[0086] Step S600: Calculate the leakage rate based on the pressure decay rate and the entropy change rate of the quantum Shannon entropy corresponding to the optimal decomposition scale, and obtain the leakage result based on the leakage rate.

[0087] The embodiment is based on the pressure decay rate of the non-invasive blood pressure simulator and the entropy change rate of the quantum Shannon entropy of the optimal decomposition scale to calculate the leakage rate, and based on the leakage rate to judge the leakage of the non-invasive blood pressure simulator.

[0088] Specifically, the calculation formula of the leakage rate is:

[0089] ;

[0090] wherein, is the leakage rate, is the corrected pressure value of the non-invasive blood pressure simulator, is the pressure decay rate of the non-invasive blood pressure simulator, , is the measured pressure value of the non-invasive blood pressure simulator, is the environmental disturbance, is the coupling coefficient, used to adjust the proportion of the pressure decay rate of the non-invasive blood pressure simulator in the leakage rate, and the value can be set according to experience, is the quantum Shannon entropy under the optimal decomposition scale, reflecting the real leakage characteristics after denoising, is the entropy change rate of the quantum Shannon entropy.

[0091] By combining the traditional pressure decay rate with the entropy change rate of the quantum Shannon entropy to calculate the leakage rate, the final leakage rate can more comprehensively and accurately reflect the leakage degree of the non-invasive blood pressure simulator, and the accuracy of the leakage detection is improved.

[0092] wherein, the environmental disturbance is calculated by the formula:

[0093] ;

[0094] wherein, is the temperature disturbance coefficient, is the real-time temperature, is the reference temperature, in the embodiment, the reference temperature is 20℃, is the electromagnetic interference coefficient, is the environmental electromagnetic field intensity.

[0095] The temperature disturbance coefficient (unit: kPa / ℃) and the electromagnetic interference coefficient (unit: kPa / dB) can be obtained by training the quantum neural network, specifically including: the quantum neural network encodes the historical pressure, temperature and electromagnetic field data into quantum states, extracts the environmental disturbance characteristics by using quantum gate operation, and trains and optimizes the quantum neural network parameters to minimize the error between the predicted disturbance and the actual disturbance. After training, the quantum neural network outputs the temperature disturbance coefficient and the electromagnetic interference coefficient .

[0096] Compared to traditional detection methods, which tend to overlook interference from environmental factors such as temperature drift and electromagnetic noise on pressure sensors, resulting in insufficient detection accuracy, this embodiment corrects the measured pressure value collected by the sensor based on the current real-time temperature and electromagnetic field strength when calculating the leakage rate, eliminating the impact of environmental fluctuations on the detection results and improving detection accuracy and stability.

[0097] After the leakage rate is calculated, the leakage result is obtained by analyzing the leakage rate. Specifically, when the leakage rate is greater than or equal to the first leakage threshold and less than the second leakage threshold, the leakage result is a slight leakage; when the leakage rate is greater than or equal to the second leakage threshold, the leakage result is a significant leakage. In this embodiment, the leakage of the non-invasive blood pressure simulator is determined, including:

[0098] when When the non-invasive blood pressure simulator is detected, it is determined that there is a slight leak;

[0099] when When the non-invasive blood pressure simulator is detected, it is determined that there is a significant leakage;

[0100] in, is the first leakage threshold, The specific values ​​of the first leakage threshold and the second leakage threshold can be determined according to actual conditions.

[0101] In summary, this embodiment first acquires a pressure decay signal sequence under static conditions. This pressure decay signal sequence contains information about the pressure changes over time in the non-invasive blood pressure simulator, indicating whether the simulator is leaking and the extent of the leak. Quantum phase encoding is then used to map the pressure signal in the pressure decay signal sequence to a quantum state, enhancing the signal's characterization capabilities and improving the sensitivity of identifying subtle leaks. A mixed wavelet basis function is then used to perform a multi-scale decomposition of the pressure signal quantum sequence. The quantum Shannon entropy corresponding to different decomposition scales is then calculated, and the optimal decomposition scale is selected using a quantum annealing algorithm. At the optimal decomposition scale, the pressure signal is decomposed into frequency components that best distinguish leak characteristics from normal pressure decay. Furthermore, since the quantum Shannon entropy, as a measure of signal uncertainty, directly reflects changes in signal complexity, the entropy change rate corresponding to the optimal decomposition scale more accurately reflects the dynamic changes in the pressure decay process. Leaks can cause transient fluctuations in the pressure signal, which manifest as an abnormal increase in the entropy change rate at the optimal scale, enabling precise location of leak events. By integrating the dual indicators of entropy change rate and pressure decay rate to jointly evaluate the leakage rate in the time domain (pressure change) and frequency domain (complexity change), the robustness of leakage detection is significantly improved.
