Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is logical
The component for the embodiment of the present invention being often described and illustrated herein in the accompanying drawings can be arranged and be designed with a variety of different configurations.
Therefore, claimed invention is not intended to limit to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but be merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
Embodiment one:
Fig. 1 shows a kind of first implementation flow chart of fetal heart monitoring method of the offer of the embodiment of the present invention one, is described in detail such as
Under:
In step s101, fetal monitoring data are obtained, the fetal monitoring data include fetal heart rate data.
Wherein, Fetal Heart Rate refers to the heart rate of fetus, and the range of normal value is general to be supervised by fetal rhythm at 110~160 beats/min
The Fetal Heart Rate probe for protecting instrument is obtained using the line reflection principle of ultrasonic wave.When obtaining fetal heart rate data, usually first obtains and set
The long Fetal Heart Rate value of timing, in practical applications, the Fetal Heart Rate value of the setting duration is usually continuous 15 minutes~20 minutes
Fetal Heart Rate value.But since the factors such as movement of the foetus, uterine contraction, pregnant woman's position chanP may cause what foetus ECG monitor was calculated
Fetal Heart Rate value exceeds the measurement range of foetus ECG monitor, that is, the case where invalid value occurs, therefore, also need to acquired Fetal Heart Rate
Value is pre-processed, and the invalid value is deleted.
According to the regulation in currency of Chinese medical industry standard " YY 0449-2009 ultrasonic Doppler fetal monitor ", Fetal Heart Rate
Measurement and indication range exceed 65-210 beats/min of numerical value as invalid value, it is preferable that in the present embodiment to the Fetal Heart Rate
When value is pre-processed, 240 beats/min or 30 beats/min less than second fetus heart rate threshold of the first Fetal Heart Rate threshold value of fetal rhythm will be greater than
Rate value is considered as invalid value, and by screening continuous 15 minutes~20 minutes Fetal Heart Rate values, by the tire within the scope of invalid value
Heart rate value is deleted.
Further, after deleting invalid value, also by obtaining invalid value duration interval, to what is obtained
Fetal heart rate data is handled.Such as: the invalid value as caused by the factors such as movement of the foetus, uterine contraction, pregnant woman's position chanP, invalid value
The time interval of appearance is generally lesser time interval, when the invalid value duration interval of acquisition is less than first
Between be spaced T1 when, then the Fetal Heart Rate value in the time interval is filled by linear interpolation mode；It fills up described to delete
The invalid value removed to avoid the deletion because of invalid value, and influences the continuity of data.For another example, when the Fetal Heart Rate Monitoring of pregnant woman
It interrupts or terminates, that is, when detecting the input of no fetal heart rate signal, at this point, the time for invalid value occur is then longer, to what is obtained
Fetal heart rate data is handled, and includes: at invalid value duration interval greater than the first time interval T1, and
And when less than the second time interval T2, delete processing is done to the Fetal Heart Rate value in the time interval, without filling up；Described
When invalid value duration interval is greater than the second time interval T2, acquired whole fetal heart rate datas are deleted, again
Obtain fetal heart rate data；The fetal heart rate data for abandoning this acquisition, is obtained again when occurring effective Fetal Heart Rate value next time
Take fetal heart rate data.
In step s 102, the peak value sequence of the fetal monitoring data is obtained.
Wherein, the peak value sequence for obtaining fetal monitoring data includes obtaining Fetal Heart Rate peak value sequence.
As an implementation, the Fetal Heart Rate peak value sequence that obtains includes: that different first low of cutoff frequency is arranged
Bandpass filter and the second low-pass filter, are filtered Fetal Heart Rate value, obtain Fetal Heart Rate peak value sequence.
Specifically, when obtaining the Fetal Heart Rate peak value sequence, first acquired Fetal Heart Rate value is smoothed, and
By first low-pass filter and second low-pass filter respectively to the Fetal Heart Rate value filtering, the first low pass is obtained
Filtering signal and the second low-pass filter signal；Extract the difference of first low-pass filter signal Yu second low-pass filter signal
Value signal；Obtain Fetal Heart Rate peak value sequence.It should be noted that first low-pass filter and second low-pass filter
For the different low-pass filter of two cutoff frequencies, for example, the cutoff frequency of first low-pass filter is greater than described second
The cutoff frequency of low-pass filter；By being compared to the signal obtained after the filtering of described two low-pass filters, it is poor to extract
Value signal avoids to obtain accurate Fetal Heart Rate peak value sequence because of appearance pseudo- peak when baseline fetal heart rate is higher, or in tire
Occurs the problem of leakage peak when heart rate baseline is lower.
In step s 103, the peak value sequence is analyzed, fetal monitoring data variation information, the fetal monitoring data variation letter are obtained
Breath includes the corresponding baseline fetal heart rate of the fetal heart rate data and the variation frequency that Fetal Heart Rate accelerates or Fetal Heart Rate slows down.
Wherein, the baseline fetal heart rate, in the case where referring to no movement of the foetus and uterine contraction, the Fetal Heart Rate for lasting 10 minutes is average
It is worth, in the present embodiment, normal baseline fetal heart rate is 110~160bpm, when baseline fetal heart rate is greater than 160bpm, then it represents that fetus
Tachycardia；When baseline fetal heart rate is less than 110bpm, then it represents that fetus bradycardia.It should be noted that the Fetal Heart Rate
Baseline can be obtained by mean value mode or low-pass filtering mode.For example, in embodiments of the present invention, the baseline fetal heart rate
The Fetal Heart Rate value filtering can be obtained by first low-pass filter.
In addition, when obtaining the variation frequency that Fetal Heart Rate accelerates or Fetal Heart Rate slows down, first by identifying the Fetal Heart Rate
The peaks and troughs of peak value sequence, then obtain the variation frequency that Fetal Heart Rate accelerates or Fetal Heart Rate slows down；Due to the Fetal Heart Rate peak
Value sequence exists simultaneously positive peak value and negative peak, and positive peak value indicates that Fetal Heart Rate value increases, and negative peak indicates fetal rhythm
Rate value reduces, and therefore, need to only be identified by the peaks and troughs to Fetal Heart Rate peak value sequence, carry out Fetal Heart Rate acceleration and tire
The peak value of heart rate decelerations obtains, and can obtain the variation frequency that Fetal Heart Rate accelerates or Fetal Heart Rate slows down.
Specifically, according to American National child health care and human developmental research institute (NICHD) propose about fetal rhythm electronics
Mode in monitoring curve interpreting blueprints guide, extraction duration meet peaks and troughs defined in the guide, can carry out tire
The peak value that heart rate accelerates and Fetal Heart Rate slows down obtains.
In step S104, according to the fetal monitoring data variation information, corresponding audio is played.
After carrying out the peak value that Fetal Heart Rate accelerates and Fetal Heart Rate slows down and obtaining, the Fetal Heart Rate is obtained according to the peak value and is added
The frequency that speed and Fetal Heart Rate slow down, in the present embodiment, the general Fetal Heart Rate by statistics nearest 10 minutes accelerates or fetal rhythm
The number that rate is slowed down, preliminary judgement fetal heart monitoring effect is carried out according to fetal heart monitoring curve score method, for not lower than 8 points
Qualified fetal rhythm, further according to Fetal Heart Rate acceleration times trend and Fetal Heart Rate deceleration number trend distinguish fetus be in process of falling asleep,
It sleep soundly process, wakeup process or restless process, plays corresponding audio.
It should be understood that the variation frequency that the Fetal Heart Rate accelerates or Fetal Heart Rate slows down not only includes in setting duration
Fetal Heart Rate accelerate or Fetal Heart Rate slow down change frequency, further include Fetal Heart Rate accelerate or Fetal Heart Rate slow down variation tendency, institute
Variation tendency is stated to accelerate by each of within the set duration continuous specified time interval Fetal Heart Rate or Fetal Heart Rate deceleration number
Increasing degree embody, when the increasing degree is positive number always, then the Fetal Heart Rate accelerates or Fetal Heart Rate deceleration variation tendency
Accelerate for Fetal Heart Rate or Fetal Heart Rate variation of slowing down gradually increases, when the increasing degree is always negative, then the Fetal Heart Rate
Accelerate or Fetal Heart Rate deceleration variation tendency is that Fetal Heart Rate accelerates or Fetal Heart Rate deceleration variation gradually decreases, when the increasing degree connects
When nearly zero, then the Fetal Heart Rate accelerates or Fetal Heart Rate deceleration variation tendency is that Fetal Heart Rate accelerates or Fetal Heart Rate deceleration becomes without obvious
Change；When the increasing degree has positive number to have negative again, then the Fetal Heart Rate accelerates or Fetal Heart Rate deceleration variation tendency is fetal rhythm
Rate accelerates or Fetal Heart Rate slows down, and variation is frequent.
Specifically, since fetus is in process of falling asleep, by the quiet transformation of trend, variation that Fetal Heart Rate accelerates or Fetal Heart Rate slows down by
It is decrescence few；Fetus is in rest state, Fetal Heart Rate accelerates or Fetal Heart Rate slows down without significant change during sleeping soundly；Fetus exists
In wakeup process, fetus is become from quiet to turn, and Fetal Heart Rate accelerates or Fetal Heart Rate slows down, and variation gradually increases；Fetus is in restless process
In, it is constantly in fortune merits and demerits journey, baseline fetal heart rate is higher (for example, baseline fetal heart rate is greater than 160bpm), and Fetal Heart Rate accelerates
Or Fetal Heart Rate slows down variation frequently.Therefore, it can be obtained by the variation frequency of baseline fetal heart rate and Fetal Heart Rate acceleration or deceleration
Fetal state, and according to acquired fetal state, corresponding audio is played, so that fetus is waken up during sleeping soundly,
It is pacified during restless.
Further, described according to the fetal monitoring data variation information, playing corresponding audio includes: by described in determination
Change threshold interval locating for the frequency；And obtain matched first audio of music parameter corresponding with the threshold interval；To
First audio got is played out, first audio includes fetal music.
In the present embodiment, when the variation frequency that Fetal Heart Rate accelerates or Fetal Heart Rate slows down is less than first threshold, Fetal Heart Rate
Curve ratio is more gentle, variation that no apparent Fetal Heart Rate accelerates or Fetal Heart Rate slows down, during indicating that fetus is likely to be in and sleep soundly,
At this point, matched fetal music is that rhythm is very fast, the higher cheerful and light-hearted type fetal music of tone, according to music rhythm and sound
Tune can choose the fetal music to match from music libraries and play out, and then by fetus from middle wake-up of sleeping soundly.Wherein, described
Rhythm is very fast, the higher cheerful and light-hearted type fetal music of tone be music rhythm be greater than third threshold value, tone be higher than the 4th threshold value tire
Teach music.
When Fetal Heart Rate accelerate or Fetal Heart Rate slow down the variation frequency be greater than second threshold when, baseline fetal heart rate it is higher (for example,
Baseline fetal heart rate is greater than 160bpm), and Fetal Heart Rate accelerates or Fetal Heart Rate slows down variation frequently, and it is hot-tempered to indicate that fetus is likely to be in
During dynamic, at this point, matched fetal music is rhythm compared with slow, the lower soft type fetal music of tone, according to sound
Happy rhythm and tone can choose the fetal music to match from music libraries and play out, and then pacify fetus.Its
In, the rhythm is lower than the 6th threshold less than the 5th threshold value, tone for music rhythm compared with slow, the lower soft type fetal music of tone
The fetal music of value.
It should be noted that in the present embodiment, when fetal heart monitoring starts, playing plain edition fetal music, supervised in fetal rhythm
During shield, if the variation frequency is greater than the first threshold and is less than the second threshold, the plain edition prenatal culture sound is still played
It is happy；When the variation frequency be less than the first threshold, then play the cheerful and light-hearted type fetal music；When the variation frequency is greater than
The second threshold then plays the soft type fetal music；Wherein, the medium-sized fetal music is greater than for music rhythm
5th threshold value is less than third threshold value, tone is greater than fetal music of the 6th threshold value less than the 4th threshold value.
The audio file of first audio can be added by external interface, be deleted, and by the type of audio file point
Class storage plays to carry out the audio of respective type according to fetal heart rate variation trend.
Further, the second of a kind of fetal heart monitoring method provided Fig. 2 shows the embodiment of the present invention one realizes stream
Cheng Tu further includes step S105, exports prompt information, the prompt after the frequency first audio of broadcasting according to variation
Information is used in monitoring abnormal fetal heart rate, reminds medical staff note that further reducing gestation danger.Specifically, the side
Method includes:
If the variation frequency is less than first threshold, and after first audio for playing setting duration, the variation
The frequency is constant or reduces, then exports the first prompt information；That is, after playing the fetal music of cheerful and light-hearted type of setting duration, judgement
Fetal Heart Rate accelerates or Fetal Heart Rate slows down, and whether variation increases, if it is not, then exporting the first prompt information；First prompt information can
Can also be carried out by loudspeaker device or audio player by showing output in the form of picture or text in the display
Voice output.Such as output is similar to the one or more of the text of " fetal heart rate curve is gentle ", picture or speech prompt information
Combination.Wherein, described " setting duration " is selected according to the actual situation, it is preferable that the setting duration can be 3~5 minutes.
If the variation frequency is greater than second threshold, and after first audio for playing setting duration, the variation
The frequency is constant or increases, then exports the second prompt information, and the first threshold is less than the second threshold.That is, being set playing
After the fetal music of the soft type of duration, judge that Fetal Heart Rate accelerates or whether Fetal Heart Rate deceleration variation is reduced, if it is not, then output mentions
Show information；The prompt information can be showing output in the form of picture or text in the display, can also be by raising
Sound device device or audio player carry out voice output.Such as output is similar to text, picture or the language of " Fetal Heart Rate frequently accelerates "

The embodiment of the present invention, which passes through, obtains fetal monitoring data and the corresponding fetal monitoring data variation information of the fetal monitoring data, then
According to the fetal monitoring data variation information, corresponding audio is played automatically, so that just locating during fetal heart monitoring if there is fetus
When the state of sleeping soundly or restless state, fetus by fetal anaking or can be pacified by suitable audio.Meanwhile at pregnant woman
When nervous psychological condition, plays audio and additionally aid the mood for adjusting pregnant woman, and then improve undesirable fetal heart monitoring item
Part, fetal heart monitoring is unqualified caused by avoiding because of the non-pathological factor of pregnant woman or fetus, so that the result and tire of fetal heart monitoring
The time of day of youngster is more consistent.
Embodiment two:
Fig. 3 shows a kind of implementation flow chart of fetal heart monitoring method provided by Embodiment 2 of the present invention, and the present invention is implemented
The difference of a kind of fetal heart monitoring method that a kind of fetal heart monitoring method that example two provides is provided with embodiment one is, the fetal monitoring
Data further include uterine contraction pressure data, and the corresponding fetal monitoring data variation information of the uterine contraction pressure data includes uterine contraction rule
Rule, described according to the fetal monitoring data variation information, playing corresponding audio includes: to play first according to the uterine contraction rule
Audio or the second audio；First audio includes fetal music, and second audio includes respiration direction voice.
Wherein, in step s 201: obtain uterine contraction pressure data generally pass through the uterine contraction pressure probe of foetus ECG monitor into
Row obtains.When carrying out the acquisition of uterine contraction pressure data, the uterine contraction pressure value of setting duration is usually first obtained, in practical applications,
The uterine contraction pressure value of the setting duration is usually continuous 15 minutes~20 minutes uterine contraction pressure values.
Preferably, when obtaining uterine contraction pressure data, the invalid Fetal Heart Rate value also obtained by judgement is lasting
Whether time interval is greater than second time interval, if so, deleting acquired whole uterine contraction pressure datas, reacquires
Uterine contraction pressure data；The uterine contraction pressure data of this acquisition is abandoned, when occurring effective uterine contraction pressure value next time again
Obtain uterine contraction pressure data.
After obtaining uterine contraction pressure data, due to needing to carry out uterine contraction law-analysing to the acquisition uterine contraction pressure data,
Therefore, it is also desirable to obtain the corresponding uterine contraction pressure peak sequence of the uterine contraction pressure data.In step S202, the palace is obtained
When compression pressure peak value sequence, the uterine contraction pressure value of acquisition is smoothed first, and passes through third low-pass filter
Baseline filtering is carried out to the uterine contraction pressure value, obtains and filters preceding and filtered uterine contraction pressure difference value, and extract the duration
Greater than the positive peak value of setting duration.
It should be understood that the uterine contraction pressure value is possible to by uterine contraction, maternal posture change, puerpera's breathing etc.
, there is the change of uterine contraction baseline, also, different puerperas in the influence of factor, and the intensity of uterine contraction pressure is different, simple with one
Fixed threshold carries out uterine contraction identification as the mode of uterine contraction baseline, it is possible to by puerpera because of uterine contraction caused by position chanP or breathing
Pressure value variation mistake is identified as uterine contraction pressure change, in turn, pseudo- peak occurs in the identification of uterine contraction peak value, in addition, also may be used
The uterine contraction pressure change of relative weak can not be recognized, in turn, in uterine contraction peak value in the higher situation of uterine contraction pressure baseline
Occurs the case where leakage peak when identification, so that the accuracy of uterine contraction peak value identification is not high.Therefore, the side that the present invention is filtered by baseline
Formula carries out the identification of uterine contraction pressure peak, gets uterine contraction pressure peak sequence as shown in Figure 4, avoids and knows in uterine contraction peak value
Occur the case where pseudo- peak or leakage peak when other, improves the accuracy of uterine contraction peak value identification.
In step S203, after obtaining uterine contraction pressure peak sequence, the judgement of uterine contraction rule need to be carried out.Specifically, exist
In the present embodiment, according to the uterine contraction pressure peak sequence, uterine contraction duration and uterine contraction frequency are obtained, and hold according to the contracting
Continuous time and uterine contraction frequency judge uterine contraction rule；Wherein, the uterine contraction rule includes: periodic regular uterine contraction and sporadic
Irregular uterine contraction.
Since sporadic irregular uterine contraction is several weeks before delivery of fetus, because uterus muscle is more sensitive, it will appearance is not advised
Uterine contraction then, duration is short, and strength is weak, or is only limited to uterus lower part.Stop again after a few hours, uterus cannot be made
Neck mouth is opened, therefore not just before giving birth, this uterine contraction irregularities, aperiodicity is false uterine contraction.And periodically regular uterine contraction is to face
The contraction of the regular property in uterus when production, as shown in Figure 4 and Figure 5, uterotonic interval time at initial stage are about 10 minutes primary,
Pregnant woman feels abdomen throe, and the duration of subsequent throe gradually extends, until 40 seconds~60 seconds.Degree also aggravates therewith, interval
Time shortens, and about 3~5 minutes.Therefore, when carrying out uterine contraction rule and judge, according to above-mentioned periodic rule uterine contraction and accidental
The difference of the irregular uterine contraction of property is judged.
In the present embodiment, as shown in figure 5, according to the uterine contraction pressure peak sequence A, obtain uterine contraction duration △ T and
Uterine contraction frequency △ F, wherein the position intersected uterine contraction pressure peak sequence A and baseline B includes Ts and Te, defines uterine contraction peak value sequence
The initial position of positive peak value is Ts in column, and the position that positive peak value terminates is Te, then the duration △ T=of single uterine contraction
Te-Ts；And the interval between the initial position of two neighboring positive peak value, as uterine contraction frequency △ F, and then obtain uterine contraction and continue
Time △ T and uterine contraction frequency △ F, to carry out the judgement of uterine contraction rule.
Further, described according to uterine contraction rule in step S204, it plays the first audio or the second audio includes:
If the uterine contraction rule is periodically regular uterine contraction, the second audio is played, if in the playing process of second audio, tire
There are Heart rate decelerations in heart rate data, then exports third prompt information；If the uterine contraction rule is sporadic irregular uterine contraction,
The first audio is played according to the variation frequency.
Specifically, second audio is respiration direction voice, and the respiration direction voice includes uterine contraction respiration direction
Voice and eupnea instruct voice.Uterine contraction respiration direction mainly instructs pregnant woman to start when uterine contraction arrives with nose depth air-breathing
With with the slow expiration that is slow of speech, and according to certain frequency continue it is rhythmic use nose, exhaled with mouth, until this uterine contraction
Terminate, instruct pregnant woman to start eupnea at the end of this uterine contraction, uterine contraction arrives until next time.
When carrying out the broadcasting of the second audio, need to be toggled according to contraction strength, uterine contraction duration and uterine contraction frequency
The uterine contraction respiration direction voice and eupnea of broadcasting instruct voice.That is, according to the uterine contraction pressure peak retrieval uterine contraction
Intensity, single uterine contraction duration △ T, uterine contraction frequency △ F information, and according to the contraction strength of acquisition, single uterine contraction continue when
Between △ T, uterine contraction frequency △ F information speculate pregnant woman's stages of labor situation, and whether occur in conjunction with uterine contraction, uterine contraction initiating events play not
Same respiration direction voice instructs pregnant woman to carry out correct respiratory ventilation, to alleviate uterine contraction bring throe and discomfort, and prevents
The malaise symptoms such as dizziness, nausea caused by pregnant woman's breathing is improper.
In the present embodiment, specifically, according to uterine contraction pressure peak sequence judge whether uterine contraction pressure whether rise or under
Drop, when uterine contraction pressure peak series is positive peak value, representative is currently at uterine contraction process, and the rising of peak value is then uterine contraction pressure
Rise, the decline of peak value, the decline of uterine contraction pressure.When detecting that uterine contraction pressure is begun to ramp up, indicate that new uterine contraction occurs, from
Dynamic starting uterine contraction respiration direction voice play function, and uterine contraction respiration direction is played during uterine contraction；When detecting uterine contraction pressure
It when power gradually decreases, indicates that this uterine contraction gradually terminates, when this uterine contraction pressure value no longer declines, switches to eupnea and refer to
It leads, waits the arrival of uterine contraction next time.
In addition, the audio file of second audio can be added by external interface, be deleted, and press the class of audio file
Type classification storage plays to carry out the audio of respective type according to uterine contraction rule.
Wherein, in step S205, if fetal heart rate data shows fetal rhythm and subtracts in the playing process of second audio
Speed then exports third prompt information；The third prompt information can be shown in the display in the form of picture or text
Show output, voice output can also be carried out by loudspeaker device or audio player.Such as output is similar to " Heart rate decelerations "
One or more of combinations of text, picture or speech prompt information.
