本发明涉及数据处理领域，尤其涉及一种提高胎心率曲线效率的方法及系统。The invention relates to the field of data processing, in particular to a method and system for improving the efficiency of a fetal heart rate curve.
背景技术Background technique
在临床上，胎心率之间的变化幅度是医生对CTG图中的胎心率曲线进行分析的参考因素之一，医生可以利用胎心率之间的变化幅度，结合胎心率曲线的加速、减速等其他特征信息对胎心率曲线的变异情况进行分析，使对胎心率曲线的识别和解释更加全面客观。但目前临床上对胎心率曲线进行显示、打印时由于空间的限制必须对曲线进行压缩，导致难以直接从胎心率曲线中分析出胎心率之间的变化幅度，这种现状导致医生不方便对胎心率之间的变化幅度情况进行识别，只能凭经验进行粗略的估算；同时由于胎心率之间的变化是实时出现，而目前临床上都是在监护完成后才能对胎心率之间的变化幅度进行分析，根据变化幅度的大小然后结合胎心率基线、加速减速等参数，根据特定的评分体系，最终得出分值评判胎儿状态的评价，不能实时的了解到胎心率之间的变化情况，这种现状会导致不能及时地了解胎心率之间的变化幅度的演变趋势，造成后续识别和分析胎心率曲线的时间延迟，这样会降低后续处理的效率，导致宝贵的时间浪费。In clinical practice, the range of variation between fetal heart rates is one of the reference factors for doctors to analyze the fetal heart rate curve in the CTG image. Doctors can use the range of variation between fetal heart rates and the acceleration of the fetal heart rate curve , deceleration and other characteristic information to analyze the variation of the fetal heart rate curve, making the identification and interpretation of the fetal heart rate curve more comprehensive and objective. However, at present, when displaying and printing the fetal heart rate curve clinically, the curve must be compressed due to space constraints, making it difficult to directly analyze the variation range of the fetal heart rate from the fetal heart rate curve. It is convenient to identify the variation range of fetal heart rate, which can only be roughly estimated based on experience; at the same time, because the change of fetal heart rate occurs in real time, currently the fetal heart rate can only be detected after the monitoring is completed. According to the magnitude of the change, combined with the fetal heart rate baseline, acceleration and deceleration and other parameters, according to a specific scoring system, the final score is obtained to judge the evaluation of the fetal state, and the fetal heart rate cannot be understood in real time. This situation will lead to the inability to timely understand the evolution trend of the variation range of fetal heart rate, resulting in a delay in the subsequent identification and analysis of fetal heart rate curves, which will reduce the efficiency of subsequent processing, resulting in Waste of precious time.

具体实施方式Detailed ways
如图1所示，本发明公开了一种提高胎心率曲线效率的方法，包括如下步骤：As shown in Figure 1, the present invention discloses a method for improving the efficiency of the fetal heart rate curve, comprising the following steps:
在步骤S1中，选取在预定时长内已获取的胎心率监护曲线数据；In step S1, select the fetal heart rate monitoring curve data acquired within a predetermined period of time;
在步骤S2中，实时计算胎心率之间的变化幅度；In step S2, the range of change between fetal heart rates is calculated in real time;
在步骤S3中，判断所述计算的胎心率之间的变化幅度是否超过预设定阈值，如果没有则返回步骤S2，如果超过则进入步骤S4；In step S3, it is judged whether the range of change between the calculated fetal heart rates exceeds a preset threshold, if not, return to step S2, and if it exceeds, enter step S4;
在步骤S4中，实时标识胎心率之间的变化幅度；In step S4, the range of change between fetal heart rates is identified in real time;
在步骤S5中，判断所采集的胎心率监护曲线数据是否都已标识完成，如果是，则进入步骤S6，否则返回步骤S1；In step S5, it is judged whether the collected fetal heart rate monitoring curve data has been marked, if yes, then enter step S6, otherwise return to step S1;
在步骤S6中，存储、实时显示、打印所述胎心率曲线及与其时间对齐的标识信息。In step S6, the fetal heart rate curve and the identification information aligned with its time are stored, displayed in real time, and printed.
在步骤S2中，可以直接采用计算该曲线段的最大胎心率值与最小胎心率值的差值方法来得到该曲线段的胎心率之间的变化幅度值，或者可以先对胎心率曲线中的加速或减速进行标记，然后计算该曲线段标记区域外的最大胎心率值与最小胎心率值的差值方法来得到该曲线段的胎心率之间的变化幅度值。In step S2, the method of calculating the difference between the maximum fetal heart rate value and the minimum fetal heart rate value of the curve segment can be directly used to obtain the change range value between the fetal heart rate values of the curve segment, or the fetal heart rate can be calculated first. Mark the acceleration or deceleration in the rate curve, and then calculate the difference between the maximum fetal heart rate value and the minimum fetal heart rate value outside the marked area of the curve segment to obtain the range of change between the fetal heart rate values of the curve segment.
在所述步骤S4中，在胎心率曲线显示范围之外、且能够同屏显示或者同时打印的区域内设立时间轴，并与所述胎心率曲线进行时间对齐，并在超过所述预设定阈值的时间段内对计算出的该曲线段的胎心率之间的变化幅度用标识符进行标识。该标识符可以是几何图形、文字、字母、或符号等。In the step S4, a time axis is set up outside the display range of the fetal heart rate curve and can be displayed on the same screen or printed at the same time, and time-aligned with the fetal heart rate curve, and when the predetermined The range of change between the calculated fetal heart rates of the curve segment is marked with an identifier within the time period of the threshold value. The identifier can be geometric figures, characters, letters, or symbols, etc.
作为本发明的一个实施例，在步骤S4中，包括如下步骤：As an embodiment of the present invention, in step S4, the following steps are included:
第一步骤：找出该曲线段的起点和终点，以及其对应的胎心率之间的变化幅度；The first step: find out the starting point and the ending point of the curve segment, and the variation range between the corresponding fetal heart rate;
第二步骤：判断该曲线段的胎心率之间的变化幅度是否被标记为无效（比如，该曲线段内胎心率数值不在预设定的范围内的比例超过预设值，或该曲线段被判断为加速或者减速等），如果是则在CTG图中该曲线段从起点到终点所包含的平面区域内不对该幅度进行标识，这样做避免了不准确或者是一过性胎心率变化的数据导致标识变化幅度结果的偏差；如果不是，则在CTG图中该曲线段从起点到终点所包含的平面区域内寻找一块连续且空白的平面区域（比如，选择在胎心率曲线图所在的坐标系外的空白区域，可以优选在胎心率曲线图所在的坐标系和宫缩曲线图的坐标系之间的空白区域，另外还可以是在所述预定时长内已获取的胎心率监护曲线数据的最大和最小极值所构成的水平区域之外）作为标识内容填充处，要求该作为标识内容填充处的区域在时间上与该时间段内所对应的胎心率曲线对齐，但不能覆盖到该时间段所对应的胎心率曲线，防止标识内容影响胎心率曲线本身的查看，由于根据背景技术的描述，目前临床上对胎心率曲线进行显示、打印时由于空间的限制必须对曲线进行压缩，因此标识在曲线上是不方便查看的，所以需要在这个特殊的情况下，寻找到不影响查看且与曲线时间对应的区域中显示标识内容；The second step: determine whether the range of change between the fetal heart rates in the curve segment is marked as invalid (for example, the proportion of fetal heart rate values in the curve segment that is not within the preset range exceeds the preset value, or the curve segment is marked as invalid. Judging as acceleration or deceleration, etc.), if it is, the amplitude will not be marked in the plane area included in the curve segment from the start point to the end point in the CTG diagram, so as to avoid inaccurate or transient fetal heart rate changes The data lead to the deviation of the result of the identification change range; if not, search for a continuous and blank plane area in the plane area included in the curve segment from the start point to the end point in the CTG diagram (for example, select the area where the fetal heart rate curve graph is located) The blank area outside the coordinate system can preferably be the blank area between the coordinate system of the fetal heart rate curve and the coordinate system of the uterine contraction curve, and can also be the fetal heart rate monitoring data acquired within the predetermined time period. outside the horizontal area formed by the maximum and minimum extremum values of the curve data) as the filling place of the identification content, it is required that the area used as the filling place of the identification content is aligned with the corresponding fetal heart rate curve in the time period, but it cannot Cover the fetal heart rate curve corresponding to this time period to prevent the content of the logo from affecting the viewing of the fetal heart rate curve itself. According to the description of the background technology, currently the fetal heart rate curve must be displayed and printed clinically due to space constraints. The curve is compressed, so the logo is inconvenient to view on the curve, so in this special case, it is necessary to find the area that does not affect the viewing and corresponds to the time of the curve to display the logo content;
第三步骤：在所述选取的空白的平面区域内用标识符标识出该曲线段的胎心率之间的变化幅度，且该曲线段的胎心率之间的变化幅度在不同的预设区间范围用不同的标识符进行标识，例如：判断该曲线段的胎心率之间的变化幅度是否在预设的区间范围内，若幅度在该范围内，则在所述的区域内填充特定的几何图形A“★”；若幅度超过所述的预设的区间范围上限，则在所述的区域内填充特定的几何图形B“■”；若幅度低于所述的预设的区间范围下限，则在所述的区域内填充特定的几何图形C“▲”。该步骤中所述的预设的区间范围还可以是多个范围，对应的在每个范围中要标记互不相同的特定的几何图形；所述的特定的符号A、B、C还可以是线段、圆点、菱形等其他互不相同的几何图形。在胎心率曲线分析的领域，一般来说会存在对胎心率之间的变化幅度进行多个区域的划分，以细分其变化的大小程度，比如变化幅度缺失、变化幅度微小、变化幅度中度、变化幅度显著等，因此需要采用不同的几何图形进行标识。Step 3: Use an identifier to identify the variation range of the fetal heart rate of the curve segment in the selected blank plane area, and the range of variation of the fetal heart rate of the curve segment is within different presets The interval ranges are marked with different identifiers, for example: to determine whether the range of change between the fetal heart rates of the curve segment is within the preset interval range, if the range is within the range, fill in the specified area The geometric figure A "★"; if the amplitude exceeds the upper limit of the preset interval range, fill the specific geometric figure B "■" in the area; if the amplitude is lower than the preset interval range The lower limit, then fill the specific geometric figure C "▲" in the said area. The preset interval range described in this step can also be a plurality of ranges, and the corresponding specific geometric figures to be marked in each range are different from each other; the specific symbols A, B, and C can also be Line segments, dots, rhombuses and other different geometric figures. In the field of fetal heart rate curve analysis, generally speaking, there will be multiple divisions of the range of change between fetal heart rates to subdivide the magnitude of the change, such as missing range of change, small range of change, and range of change Moderate, significant change, etc., so different geometric figures need to be used for identification.
在步骤S6中包括：In step S6 include:
将对胎心率之间的变化幅度的标识信息送入存储模块，且能够在内存中存储标识信息与时间轴对应的位置信息、标识的具体内容；Send the identification information of the range of change between the fetal heart rates into the storage module, and store the identification information in the memory, the position information corresponding to the time axis, and the specific content of the identification;
将对胎心率之间的变化幅度的标识信息送入显示模块，且能够在屏幕上显示的CTG图中与时间轴对应的位置处实时显示出标识的具体内容；The identification information of the range of change between the fetal heart rates is sent to the display module, and the specific content of the identification can be displayed in real time at the position corresponding to the time axis in the CTG diagram displayed on the screen;
