Description

Esophagus pressure measurement identification recognition system, electronic equipment and storage medium

Technical Field

The present application relates to the field of medical technology, and more particularly, to an esophageal pressure measurement identification system, an electronic device, and a computer-readable storage medium.

Background

The esophageal pressure measurement is a golden standard for evaluating esophageal dynamic abnormity, and compared with a traditional pressure measurement mode of adopting a 4-guide or 8-guide pressure measurement catheter and gradually pulling after intubation, the high-resolution pressure measurement (the whole English name: high resolution measurement, the English name: HRM for short, including water perfusion HRM according to 21-36 channels of the esophageal HRM catheter and solid HRM with the pressure measurement channel as high as 33-36 channels) can more intuitively and accurately reflect the esophageal dynamic condition.

In order to help clinicians to better identify esophageal dynamic abnormalities by using HRM, the international HRM working group published the 1 st edition of esophageal dynamic abnormality classification in 2009, namely the classification standard of chicago, and diagnosis was mainly performed according to some technical parameters of esophageal manometry. Whether the calculation range and the calculation value of the technical parameter are accurate depends on the physiological position of the esophagus and the characteristic point identification of the pressure waveform. The Chicago algorithm primarily performs identification diagnostics based on high resolution cloud images. The esophageal manometry mark comprises a resting frame mark and a swallowing frame mark.

In the actual use process of the existing pressure measuring product, software can automatically identify the identification position, but sometimes the software has larger deviation with the correct position. Doctors and analysts are required, and according to the shapes of the pressure cloud pictures or the pressure curve graphs of the patients, human eyes judge whether the automatically recognized identification positions are correct, and manually adjust the identification positions one by one to correctly place the identification positions. The workload of doctors or analysts can be increased, individual differences also exist in human eye recognition, the recognition accuracy of the esophageal manometry markers is not high, and the esophageal dynamics analysis result is influenced.

Therefore, how to improve the identification accuracy of the esophageal manometry mark is a problem to be solved by those skilled in the art.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application discloses esophagus pressure measurement identification system, which improves the identification accuracy of esophagus pressure measurement identification.

Referring to fig. 1, a structural diagram of an esophageal manometry identification system disclosed in an embodiment of the present application is shown in fig. 1, and includes:

the device comprises an acquisition module 101, a storage module and a processing module, wherein the acquisition module 101 is used for acquiring a resting frame pressure cloud picture and a swallowing frame pressure cloud picture and dividing the resting frame pressure cloud picture into N parts according to the position of an esophagus; wherein N is a positive integer greater than 1;

the high-resolution cloud chart represents the change relation of pressure data with anatomical positions and time, the pressure value is represented by colors, the colors are warmer when the pressure is higher, the colors are cooler when the pressure is lower, the horizontal axis is a time axis, and the vertical axis is the anatomical positions of the esophagus. In this embodiment, the high resolution cloud images include a resting frame pressure cloud image (i.e., a pressure cloud image of each esophageal position when not swallowing) and a swallowing frame pressure cloud image (i.e., a pressure cloud image of each esophageal position when swallowing), which are from top to bottom corresponding to the esophageal positions of a human body respectively.

In a specific implementation, the obtaining module 101 first obtains a resting frame pressure cloud and a swallowing frame pressure cloud. Because the partial esophageal pressure measurement mark has unique position characteristics, for example, the UES position must be on the upper part of the pressure cloud picture, and the LES position must be on the lower part of the pressure cloud picture, the resting frame pressure cloud picture can be divided into a plurality of parts according to the esophageal position, and for a specific division mode, a person skilled in the art can flexibly set according to the actual esophageal length, UES height, LES height and the like of the esophageal anatomical position, and the specific division mode is not limited herein. In the subsequent analysis and identification process, only the part corresponding to the esophagus pressure measurement mark needs to be analyzed, so that the workload of calculation in the identification process is reduced, and the identification speed is improved.

A rest frame identification determining module 102, configured to determine a UES position according to the pressure sum of each esophageal position at the uppermost portion of the rest frame pressure cloud, determine an LES position according to the pressure sum of the end-of-breath time at the lowermost portion of the rest frame pressure cloud, and determine an LES upper edge position and an LES lower edge position according to an intersection point of an interpolation curve of the pressure sum and a median line at each end-of-breath time;

in a specific implementation, the determine resting frame identification module 102 is responsible for identifying a resting frame identification in the resting frame pressure cloud, which mainly includes a UES position, an LES position, and an LES top and bottom edge position (i.e., an LES top edge position and an LES bottom edge position). Specifically, for the position of the UES where the position of the UES is the maximum pressure value, the sum of the pressure data of each esophageal position at the uppermost part of the resting frame pressure cloud chart along with the time change is projected on the ordinate, and the ordinate position where the maximum value is located on the ordinate axis is identified, that is, the position of the UES. It will be appreciated that in practical situations a plurality of maximum pressure sums may occur, in which case an average of several maximum pressure sums and corresponding positions may be taken.

For the LES position, i.e., the position where the pressure at the end of breathing is maximum, because the diaphragm is lifted when the patient performs inspiration motion, the strength of the diaphragm is strengthened, but the strength of the diaphragm is weakened when the patient exhales, but the LES does not fluctuate along with breathing, the pressure at the end of expiration is basically the pressure of the LES, wherein the intra-abdominal pressure periodically changes along with the position of the diaphragm band, the pressure decreases during expiration, and the pressure increases during inspiration, and the time at the end of breathing can be identified by using the change rule, and a specific identification method will be described in detail in the following embodiments. And after the end-of-breath time is identified, projecting the sum of the pressures at the end-of-breath time to the ordinate, and identifying the ordinate position where the maximum value on the ordinate is located, namely the LES position.

The upper edge and the lower edge of the LES are covered by an LES high-pressure belt which is the upper edge and the lower edge of the high-pressure belt, and the position is a color jump position in visual sense. Specifically, the sum of the pressure values at each end-expiratory time is projected on a vertical axis, the pressure and data on the vertical axis are interpolated to obtain a pressure curve P2, the pressure on the vertical axis and a median line Pmid are obtained, the intersection point of the median line Pmid and the curve P2 is found, and two intersection points up and down which are respectively closest to the LES position are obtained. The positions of up and down on the ordinate axis are the corresponding positions of the upper edge and the lower edge of the LES.

The determination UES channel relaxation identification module 103 is configured to determine a pressure lowest point on the UES channel corresponding to the UES position in the swallowing frame pressure cloud map as a UES relaxation lowest point, and determine a UES relaxation starting position and a UES relaxation ending position according to an intersection point of an interpolation curve of a pressure value of the UES channel and a second reference line and a third reference line; the second datum line is a statistical pressure value at the left end of the UES lowest loose point, and the third datum line is a statistical pressure value at the right end of the UES lowest loose point;

in a particular implementation, the determine UES channel relaxation identification module 103 is responsible for identifying UES relaxation nadir, start and end locations in the swallow frame identification in the swallow frame pressure cloud. Specifically, for the lowest point of the UES relaxation, the UES position identified in the resting frame pressure cloud in the previous module is corresponding to the swallowing frame pressure cloud to determine the UES channel, and the value of the pressure on the channel changing with time is found to be the lowest point of the pressure, i.e. the lowest point of the UES relaxation.

For the initial and final positions of the UES relaxation, a second datum line and a third datum line are firstly set, wherein the second datum line is determined by a pressure value at the left end of the UES relaxation lowest point, and the second datum line is determined by a pressure value at the right end of the UES relaxation lowest point. The specific numerical value determination method of the second datum line comprises the following steps: collecting a large amount of UES channel pressure data of the patient, manually marking the pressure value at the left end of the relaxation lowest point of the patient, solving the quantile points of all the manual marks relative to the channel pressure data, and fitting all the quantile points by adopting a straight line with y being equal to b to obtain a determined value of b, namely the specific numerical value of the second datum line. For example, if the found quantile point is 3/4, the pressure value at the left end of the relaxation lowest point of the artificial mark has 8 data of 1, 2, 3, 4, 5, 6, 7 and 8, and 8 times 3/4 equals 6, then the 3/4 quantile point is the 6 th data in the 8 data sorted from small to large, that is, the value of the 3/4 quantile point is 6, and the second reference line is 6. The determination mode of the specific numerical value of each datum line is similar to that of the datum line, and is not described in detail later. In addition, the pressure values on the UES channel are interpolated to obtain an interpolated curve P3, wherein the intersection point of the second reference line and the P3, which is on the left of the UES relaxation lowest point and is closest to the UES relaxation lowest point, is the UES relaxation starting position, and the intersection point of the third reference line and the P3, which is on the right of the UES relaxation lowest point and is closest to the UES relaxation lowest point, is the UES relaxation ending position.

The swallowing wave identification determining module 104 is configured to determine a position corresponding to a maximum pressure value on a target channel as a highest pressure wave point on the target channel, and determine a peak type, a swallowing wave starting position, and a swallowing wave ending position of the target channel according to an intersection point of an interpolation curve of a pressure value of the target channel and a fourth reference line; the target channel is a channel which is in the swallowing frame pressure cloud picture and is located n centimeters upwards from the upper edge of the LES, and the fourth datum line is a statistical pressure value of the target channel.

In a specific implementation, the determine swallow wave identification module 104 is responsible for identifying swallow wave identification (including pressure wave vertices, peak types, and swallow wave start and end locations) on the target passageway in the swallow frame pressure cloud. The pressure curves are divided into multimodal (bimodal, trimodal, etc.) and unimodal, with pressure channels without DP identification being unimodal and pressure channels with DP identification being bimodal. The double peaks are judged by that at least one wave trough with 10mmHg pressure wave is arranged between adjacent wave peaks, the adjacent waves are at least separated by one second, and the start and end positions of the swallowing wave comprise the double peaks under the condition that the double peaks exist. Specifically, the highest point of pressure at the upper edge L1(3cm), L2(7cm) and L3(11cm) of the LES and the start and end positions of the swallowing wave can be identified, and the identification methods of all target channels are consistent.

The highest point of the pressure wave is the maximum value P of the pressure on the target channel_max. The intersection method is also used for the peak type, the start and end positions of the swallow wave. Specifically, a fourth reference line on the target channel is set, the fourth reference line is determined according to the pressure value on the target channel, the pressure on the target channel is interpolated to obtain an interpolation curve P4, and the intersection point of the fourth reference line and P4, P, is obtained_maxThe intersection points x1, x2, …, xk on the left (sequentially away from P)_max)，P_maxThe right intersection points y1, y2, …, yk (sequentially distant from P)_max) The peak value of the target channel can be identified according to the intersection pointType, start and end positions of swallowing waves, and the embodiment is not particularly limited to the specific identification process, and will be explained in detail in the following embodiments.

The esophagus pressure measurement identification recognition system provided by the embodiment of the application determines each esophagus pressure measurement identification by means of intersection points of each interpolation curve and each reference line, and compared with a mode of relying on human eye recognition in the prior art, the recognition accuracy is higher. Taking the rest frame mark as an example, for the UES position, since the pressure near the position with the maximum pressure appears to be almost the same as the position with the maximum pressure, the position with the maximum pressure observed by human eyes on the cloud picture is easy to deviate, and this way also depends on the accuracy of cloud picture drawing, and the accuracy of this application is higher by calculating and comparing the pressure of each esophagus position at the uppermost part of the rest frame pressure cloud picture and determining the position of the maximum value. For identification of the upper edge position and the lower edge position of the LES, the positions of all breathing end moments are automatically identified, the upper edge position and the lower edge position of the LES are automatically determined by utilizing intersection points of interpolation curves and median straight lines of pressure sum of all breathing end moments, the identification process of the esophagus pressure measurement identification is digitized and imaged, individual differences caused by human eye identification can be avoided, and the identification result is more accurate. In addition, the esophagus pressure measurement identification system provided by the embodiment of the application divides the whole pressure cloud picture into a plurality of parts, so that the system is more targeted when different pressures are calculated by identifying each identification, the calculated amount is small, and the identification speed is high. Taking the UES position as an example, the pressure sum of all esophagus positions at the uppermost part of the resting frame pressure cloud picture only needs to be calculated, the pressure sum of the whole resting frame pressure cloud picture does not need to be calculated, the calculated amount in the identification process is reduced, and the identification speed is improved.

The present application further provides an electronic device, referring to fig. 5, a structure diagram of an electronic device provided in an embodiment of the present application, as shown in fig. 5, includes:

a memory 100 for storing a computer program;

the processor 200, when executing the computer program, may implement the following steps:

Specifically, the memory 100 includes a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and computer-readable instructions, and the internal memory provides an environment for the operating system and the computer-readable instructions in the non-volatile storage medium to run. The processor 200 provides computing and control capabilities for the electronic device, and when executing the computer program stored in the memory 100, the functions of the esophageal manometry identification system described above can be realized.

The electronic equipment provided by the embodiment of the application determines each esophagus pressure measurement identifier by means of intersection points of each interpolation curve and each reference line, and compared with a mode of relying on human eye identification in the prior art, the electronic equipment is high in identification accuracy. Taking the rest frame mark as an example, for the UES position, since the pressure near the position with the maximum pressure appears to be almost the same as the position with the maximum pressure, the position with the maximum pressure observed by human eyes on the cloud picture is easy to deviate, and this way also depends on the accuracy of cloud picture drawing, and the accuracy of this application is higher by calculating and comparing the pressure of each esophagus position at the uppermost part of the rest frame pressure cloud picture and determining the position of the maximum value. For identification of the upper edge position and the lower edge position of the LES, the positions of all breathing end moments are automatically identified, the upper edge position and the lower edge position of the LES are automatically determined by utilizing intersection points of interpolation curves and median straight lines of pressure sum of all breathing end moments, the identification process of the esophagus pressure measurement identification is digitized and imaged, individual differences caused by human eye identification can be avoided, and the identification result is more accurate. In addition, the electronic equipment provided by the embodiment of the application divides the whole pressure cloud picture into a plurality of parts, so that the electronic equipment is more targeted when different pressures are calculated by identifying each identifier, the calculated amount is small, and the identification speed is high. Taking the UES position as an example, the pressure sum of all esophagus positions at the uppermost part of the resting frame pressure cloud picture only needs to be calculated, the pressure sum of the whole resting frame pressure cloud picture does not need to be calculated, the calculated amount in the identification process is reduced, and the identification speed is improved.
