[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In the prior art, anorectal pressure testing works through a pressure receptor system and a signal transmission system. The contraction and relaxation of the anal canal and rectum generate pressure to squeeze the airbag, and the pressure parameters of the anorectum are obtained through signal conversion and transmission, thereby detecting its function; the pressure data depends on the pressure measuring catheter, and the pressure measuring catheter contains multiple pressure sensors. Any pressure sensor will affect the final pressure data, and the failure of the pressure sensor will cause the accuracy of the anorectal pressure analysis to decrease. In order to overcome the above technical problems, the present application proposes an anorectal pressure data analysis method, which can ensure the integrity of the anorectal pressure test data and improve the accuracy of the anorectal pressure analysis.

[0054] The present application embodiment discloses a method for analyzing anorectal pressure data, see Figure 1 As shown, the method may include the following steps:

[0055] Step S11: obtaining a pressure curve of the sensor output in the pressure measuring catheter that changes with time during anorectal pressure detection.

[0056] First, obtain the pressure curve of the sensor output in the pressure measuring catheter under anorectal pressure detection over time, that is, every sensor in the pressure measuring catheter will output the pressure data collected by the sensor, and the pressure curve over time is obtained by continuously outputting the pressure data. Figure 2 Shown is a specific pressure curve example.

[0057] After the pressure curve is obtained, in order to eliminate isolated noise points and avoid the influence of noise data, the present embodiment may first filter the pressure curve after the pressure curve is obtained; for example, the pressure curve is filtered using a sampling median filter to obtain a filtered pressure curve.

[0058] Step S12: determining a target sensor in the pressure measuring catheter; the target sensor is a sensor that does not output a pressure curve.

[0059] According to the pressure curve output by the sensor in the pressure measuring catheter, the sensor without output pressure curve can be determined and used as the target sensor. Figure 3 The figure shows a specific pressure measuring catheter, which includes 8 sensors, namely F1, F2, ..., F8; a single sensor includes one or more circumferential pressure sensor measurement points; F2 is 25mm away from F1, F3 is 335mm away from F1, F4 is 45mm away from F1, F5 is 55mm away from F1, F6 is 65mm away from F1, F7 is 75mm away from F1, and F8 is 95mm away from F1. It can be understood that the complete pressure data of the anorectum can be obtained through the pressure curves output by these 8 sensors respectively. If there is a sensor that does not output a pressure curve, it is used as a target sensor so that the pressure data of the target sensor can be supplemented later to obtain the complete pressure data of the anorectum.

[0060] Step S13: extracting the pressure values ​​of different sensors at the same time according to the pressure curve, generating the pressure value of the target sensor at the same time by fitting, so as to obtain the target pressure curve corresponding to the target sensor.

[0061] That is, the pressure value of the target sensor is obtained by fitting the pressure data collected by other sensors. According to the analysis of historical data, it is found that the pressure value of the sensor has a certain functional relationship with the pressure of the other sensors in the catheter. Therefore, the above-mentioned extraction of the pressure values ​​of different sensors at the same time according to the pressure curve and the generation of the pressure value of the target sensor at that time by fitting can include: obtaining the output pressure relationship function of the target sensor and the other sensors in the pressure measuring catheter; the output pressure relationship function is pre-constructed according to the position of each sensor in the test catheter and combined with historical pressure measuring data; based on the pressure values ​​of different sensors at the same time, the pressure value of the target sensor at that time is generated by fitting the pressure relationship function.

[0062] The process of constructing the pressure relationship function includes: determining the anatomical position corresponding to the sensor in the anorectal pressure detection according to the position of the sensor in the pressure measuring catheter; constructing corresponding pressure relationship functions for sensors corresponding to different anatomical positions based on the pressure curves output by each sensor under the historical anorectal pressure detection of the pressure measuring catheter. It can be understood that, for example Figure 4The figure shows the anatomical position corresponding to each position of the pressure measuring catheter under anorectal pressure detection. The pressure data of the anal canal position and the rectal balloon fluctuate more violently, requiring higher data accuracy, and the data outside the rectal balloon fluctuates more steadily as a whole. Therefore, the present application constructs corresponding relationship functions for different sensors according to the human body parts corresponding to each sensor under anorectal pressure detection by the pressure measuring catheter. For example, multiple polynomials can be used for the anal canal position and the rectal balloon, and linear relationship interpolation can be used to obtain data outside the rectal balloon. A specific relationship function is: y=a1x1+a2x2+a3x3....+anxn, where n is the n sensors involved in the calculation, x1, x2, ..., xn are the pressure values ​​output by the sensor, y is the pressure value of sensor y, and the sum of a1, a2, ..., an is 1; by substituting multiple sets of historical anorectal pressure measurement data, the values ​​of a1, a2, ..., an are obtained.

[0063] Step S14: performing anorectal pressure analysis based on the target pressure curve and the pressure curve.

[0064] The present application also supports automatic analysis of anorectal pressure data, and the analysis indicators include but are not limited to channel baseline pressure value, maximum pressure value, minimum pressure value, channel maximum pressure relative value, channel minimum pressure relative value, channel pressure contraction percentage, channel pressure relaxation percentage, contraction duration and relaxation duration.

[0065] In some embodiments, the anorectal pressure analysis based on the target pressure curve and the pressure curve may include: obtaining the analysis start time point selected by the user on the pressure curve; screening out the target time period with the smallest pressure standard deviation from the preset time length before the analysis start time point; obtaining the channel baseline pressure value according to the pressure data corresponding to the target time period; analyzing the pressure curve to determine the maximum pressure value and the minimum pressure value of the pressure curve. That is, the user is supported to select a certain section of the pressure curve for data analysis, specifically by selecting the analysis start time point and the analysis end time point; the channel baseline pressure value is calculated, specifically by intercepting a period of time with the smallest pressure standard deviation from the analysis start time point to the analysis start time point as the baseline calculation position; the above preset time length can be customized by the user according to usage requirements. Specifically, the pressure mean corresponding to the target time period can be used as the channel baseline pressure value; at the same time, the maximum or minimum value of the pressure curve is detected.

[0066] Specifically, the interception process of the target period with the smallest pressure standard deviation includes the following steps: obtaining the preset time length from the time before the analysis frame to the start position of the analysis frame set by the user as T, and the baseline calculation time length set by the user as t; dividing T equally into n parts, counted as Ti (i=1,...,n), and calculating Ti standard deviations respectively; selecting the smallest j parts in Ti standard deviations so that the time length satisfies the following relationship:

[0067] ;in, The intercepted pressure standard deviation duration is used as the baseline for calculating the position.

[0068] By calculating the channel baseline pressure value in the above manner, it is possible to effectively avoid baseline segments with abnormal fluctuations and calculate a suitable baseline value.

[0069] In some embodiments, the anorectal pressure analysis based on the target pressure curve and the pressure curve includes: obtaining a relative value of the maximum pressure of the channel according to the difference between the maximum pressure value and the channel baseline pressure value; obtaining a relative value of the minimum pressure of the channel according to the difference between the minimum pressure value and the channel baseline pressure value. The maximum relative value of the channel pressure of the current sensor is determined by the pressure curve, and the maximum relative value of the channel pressure = the maximum pressure value - the baseline pressure value. The relative value of the minimum pressure of the channel = the minimum pressure value - the baseline pressure value.

[0070] In some embodiments, the anorectal pressure analysis based on the target pressure curve and the pressure curve includes: obtaining the channel pressure contraction percentage according to the ratio of the maximum pressure value to the channel baseline pressure value; obtaining the channel pressure relaxation percentage according to the ratio of the minimum pressure value to the channel baseline pressure value. Channel pressure contraction percentage = maximum pressure value / channel baseline pressure value * 100%; channel pressure relaxation percentage = minimum pressure value / channel baseline pressure value * 100%

[0071] In some embodiments, the anorectal pressure analysis based on the target pressure curve and the pressure curve includes: obtaining a preset first percentage, and taking the product of the maximum pressure value and the first percentage as the contraction start and end pressure; starting from the time point corresponding to the maximum pressure value, and searching for the time points corresponding to the contraction start and end pressures along the pressure curve to both sides to obtain the contraction start time point and the contraction end time point; and obtaining the contraction duration according to the duration between the contraction start time point and the contraction end time point. Figure 2As shown, obtain the preset first percentage, start from the moment of the maximum pressure value of the channel, search from the front and back for the moment when the pressure is less than or equal to "maximum pressure value × first percentage" to determine the start position (start_contract) of contraction and the end position (end_contract) of contraction; the duration of contraction is equal to the difference between end_contract and start_contract.

[0072] Obtain a preset second percentage, and use the product of the minimum pressure value and the second percentage as the relaxation start and end pressures; starting from the time point corresponding to the minimum pressure value, search along the pressure curve to both sides for the time points corresponding to the relaxation start and end pressures to obtain the relaxation start time point and relaxation end time point; obtain the relaxation duration according to the duration between the relaxation start time point and the relaxation end time point. Figure 5 As shown, obtain the preset second percentage, start from the moment when the channel pressure is minimum, search from the front and back for the moment when the pressure is greater than or equal to "minimum pressure value × second percentage", that is, the relaxation start position (start_relax) and relaxation end position (end_relax); the relaxation duration is equal to the difference between end_relax and start_relax.

[0073] As can be seen from the above, in this embodiment, the pressure curve of the sensor output in the pressure measuring catheter under anorectal pressure detection that changes with time is obtained; the target sensor in the pressure measuring catheter is determined; the target sensor is a sensor that does not output a pressure curve; the pressure values ​​of different sensors at the same time are extracted according to the pressure curve, and the pressure value of the target sensor at the time is generated by fitting to obtain the target pressure curve corresponding to the target sensor; anorectal pressure analysis is performed based on the target pressure curve and the pressure curve. It can be seen that for the target sensor that cannot output a pressure curve in the pressure measuring catheter, the pressure value of the target sensor is fitted by the pressure curves output by the remaining sensors in the pressure measuring catheter, so as to obtain the target pressure curve corresponding to the target sensor, thereby obtaining the pressure curves of all sensors in the pressure measuring catheter, and obtaining the pressure curve of the sensor output in the pressure measuring catheter under anorectal pressure detection that changes with time; the target sensor in the pressure measuring catheter is determined; the target sensor is a sensor that does not output a pressure curve; the pressure values ​​of different sensors at the same time are extracted according to the pressure curve, and the pressure value of the target sensor at the time is generated by fitting to obtain the target pressure curve corresponding to the target sensor; anorectal pressure analysis is performed based on the target pressure curve and the pressure curve. It can be seen that for the target sensor in the pressure measuring catheter that cannot output a pressure curve, the pressure value of the target sensor is fitted through the pressure curves output by the remaining sensors in the pressure measuring catheter, so as to obtain the target pressure curve corresponding to the target sensor, thereby obtaining the pressure curves of all sensors in the pressure measuring catheter, so as to obtain complete data of the anorectal pressure test, and then perform anorectal pressure analysis based on the data to improve the accuracy of anorectal pressure analysis.

[0074] Correspondingly, the present application also discloses an anorectal pressure data analysis device, see Figure 6 As shown, the device comprises:
