Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing .
Fig. 1 is a kind of fetal monitoring alarm method of the present invention schematic flow sheet;
Fig. 2 is a kind of fetal monitoring alarm device of the present invention sketch map.
The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, a kind of fetal monitoring alarm method of the present invention, main may further comprise the steps:
Step 101: parameter safety scope and analyzing total duration are preset;
detailed process is: the window that is provided with through fetal monitoring system provides is preset the safety range of each parameter, comprising presetting of the loss of signal, baseline fetal heart rate, uterine contraction, acceleration, deceleration, short variation (STV) and long variation parameter safety scopes such as (LTV); Also need preset total duration of analyzing simultaneously, wherein the setting of total duration of this analysis need be analyzed data how long after being meant and starting analytic process altogether.And fetal monitoring system can on average be divided into the experimental process time span with the analyzing total duration, and analytic process starts the sub-time span in every interval, back once to be analyzed, and reaches setting value until total length analysis time, and analytic process just can finish; The analyzing total time span of total duration of wherein said analysis for presetting, and analyzing total time span that should be preset is littler than the time span meeting of CTG data acquisition, so even analyze end, the CTG data acquisition also can not finish; Long time when said analysis duration reaches analyzing total, data analysis process will finish, but the collection of CTG data does not finish, and can carry out the CTG data acquisition according to practical situation;
Step 102:CTG data acquisition;
start fetal monitoring system after parameter safety scope and the setting of analyzing total duration are finished, the CTG data are gathered, and the CTG data of gathering are cached in relief area.
Step 103: judge whether to reach the analyzing total duration;
are after gathering storage to data; Then need judgment data to analyze duration and whether reached the analyzing total duration; If reached the analyzing total duration, then analyze and finish, then do not proceed data analysis if reach the analyzing total duration.
Obtain the CTG data, the CTG data are analyzed;
long time when judgment data is analyzed duration and do not reached total analysis need carry out real-time analysis to data; Obtain the CTG data from relief area; Mainly according to analyzing the CTG data that duration obtains corresponding duration; Wherein this analysis duration comprises that the duration of having analyzed adds the current sub-time length that will analyze, and the length of the CTG data of therefore obtaining is the data length of having analyzed and adds the current data length that will analyze; Then the CTG number that obtains is analyzed, wherein the CTG data are analyzed main analysis CTG data corresponding parameter and whether surpass preset safety range etc.
Step 105: whether discriminatory analysis is accomplished;
Whether also need discriminatory analysis to accomplish after data are obtained and analyzed, and do not accomplish if analyze, then continue data are analyzed.
Step 106: obtain analysis result, unusual parameter is carried out labelling;
detailed process is: if discriminatory analysis is accomplished; Data analysis system can produce analysis result; And analysis result is sent in the fetal monitoring system, fetal monitoring system can detect in the safety range whether each parameter value be in setting after obtaining analysis result successively then; Judge that then this parameter is unusual parameter if surpass the safety range that is provided with, need carry out labelling this unusual parameter; For example loss of signal parameter, baseline fetal heart rate parameter, palace are pressed parameters such as parameter, acceleration parameter, deceleration parameters, short variation (STV) parameter and long variation (LTV) parameter to carry out labelling.
Step 107: the labeled abnormality parameter is reported to the police;
detailed process is: each parameter is being detected; And unusual parameter carried out after the labelling; Each parameter of fetal monitoring system meeting timing scan; Occur unusual and carried out labelling if scan certain parameter, also need continue to detect this parameter and whether meet alert if, qualified unusual parameter is reported to the police.
