Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the structured flowchart of fetal monitor.Fig. 2 is uterine contraction line () schematic diagram of buckling.Fig. 3 is uterine contraction line (two) schematic diagram of buckling.Please refer to Fig. 1, fetal monitor comprises power supply 2, probe 4, parameter plate 6, mainboard 8, display screen 10 and housing and button 12.This power supply 2, for giving probe 4, parameter plate 6, mainboard 8, display screen 10 and button (plate) power supply, ensures the energy supply of the normal operation of machine.This probe 4 generally comprises Fetal Heart Rate probe and uterine contraction is pressed probe (being piezometer or TOCO probe or pressure transducer).In certain embodiments, this probe 4 also comprises ECG electrode, for gathering the electrocardiosignal of mother and fetus.This parameter plate 6 and the corresponding setting of this probe 4 (for example have TOCO probe, just have TOCO probe parameter plate), for example, for carrying out pretreatment, Filtering Processing to the data of 4 collections of popping one's head in.On mainboard 8, there is blood processor, comprise processor, processing module etc., have and comprise that ECU, MCU etc. have module or the unit of computing ability.On mainboard 8, also there is storage device, for example memorizer or memory module etc.In certain embodiments, parameter plate 6 also can have blood processor and storage device.Mainboard 8 is connected with parameter plate 6 and display 10, carries out the work such as transfer of data, Storage and Processing, and the data of handling well are shown to display 10.Housing for combining an entirety of formation by parts except probe 4.This probe 4 is arranged in housing the corresponding interface (being generally the interface of parameter plate 6) outer and housing and links together.Button, for user provides man-machine interaction, allows user operate machine.Press and be measured as example with uterine contraction below, the running of fetal monitor is briefly described.
Open fetal monitor, TOCO probe is tied up to the abdominal part ready-to-be mother, now, fetal monitor record and preserves the force value of measurement on TOCO probe now, and force value is now called initial radix value or the initial force value of return-to-zero.TOCO probe continues to measure, obtain the force value in next moment, fetal monitor deducts this initial radix value (or force value of initial return-to-zero) by the force value in this next moment and obtains difference, and it is converted to uterine contraction by this difference and presses (size that generally this uterine contraction is pressed is 0 unit of unit to 100).Display 10 is pressed this uterine contraction to show, and is generally to show with the buckle form of line of uterine contraction.When observing uterine contraction, operator (doctor or nurse etc.) buckles line when incorrect, generally can manually carry out rezero operation one time to fetal monitor, the essence of this operation is: the force value that the value of current TOCO probe is replaced to current return-to-zero, the force value of the required new return-to-zero of calculating becoming after.The force value of the return-to-zero being replaced may be the force value of initial return-to-zero, can be also the force value of other return-to-zero.This operation presses the accuracy of measuring to play determiner to later uterine contraction, and operator's quality has been proposed to higher requirement.For example, to there being stricter requirement the opportunity of manual rezero operation, the uterine contraction line of buckling as shown in Figures 2 and 3, these uterine contractions are buckled line because make zero out of season causing, uterine contraction in Fig. 2 buckle line be in the time that pressure is higher, make zero obtain, uterine contraction in Fig. 3 buckle line be in the time that pressure is lower, make zero obtain, these two uterine contractions line of buckling is all the curve of distortion, can not be used for clinical curve.The fetal monitor that adopts at present manual return-to-zero mode is identified the qualified uterine contraction line of buckling to operator (doctor or nurse etc.) and has also been proposed comparatively strict requirement.Therefore, at present manually return-to-zero mode may cause and not carry out in time rezero operation, rezero operation time and hold inaccurately or in the time that needs make zero, do not carry out the equivalent risks such as rezero operation all the time, has certain potential safety hazard.The inventor is through repeatedly studying, design and comparing, proposing a kind of uterine contraction presses while measurement, automatically the method and apparatus making zero, having reduced uterine contraction presses the subjectivity of people while measurement to bring the undesirable element such as error, risk, improve uterine contraction and press the accuracy of measuring, meanwhile, the number of operations that has also reduced operator reduces operator's workload, make its observation and analysis curve of more concentrating one's energy, be very easy to operator and also reduced potential safety hazard simultaneously.
The uterine contraction of the embodiment of the present invention presses the core concept of the method for auto zero to be: the uterine contraction that obtains inner court contractive pressure of nearest a period of time is pressed size characteristic value, judge described uterine contraction presses size characteristic value whether to fall into predetermined threshold value scope, if, keep the force value of current return-to-zero, otherwise, the force value of current return-to-zero is adjusted.The uterine contraction of the embodiment of the present invention presses the core concept of the equipment of auto zero to be: comprise memory module and the processing unit being connected with memory module, described memory module is pressed size characteristic value and predetermined threshold value scope for the uterine contraction of storing inner court contractive pressure of nearest a period of time; The adjusting module that described processing unit comprises judge module and coordinates with judge module; Described judge module is used for judging described uterine contraction presses size characteristic value whether to fall into predetermined threshold value scope, and if so, described adjusting module is not adjusted the force value of current return-to-zero; If not, described adjusting module is adjusted the force value of current return-to-zero.By adopting uterine contraction to press size characteristic value and threshold range compare and automatically carry out deal with return to zero, realize uterine contraction and pressed the auto zero in measuring process.The uterine contraction of the embodiment of the present invention is pressed size characteristic value to generally comprise uterine contraction and is pressed average, and uterine contraction presses mean-square value and uterine contraction to press variance etc. embodiment uterine contraction to press the value of size characteristic.Mainly pressing average to press size characteristic value as uterine contraction by uterine contraction is below that example is described in detail.
