Abstract
An intelligent method and system for optimizing the intra-uterine contraceptive device is disclosed. Said method includes such steps as using ultrasonography B to measure the transverse diameter of uterine, calculating the internal transverse diameter of uterine by the linear plan algorithm, and directly choosing the intra-uterine contraceptive device according to said internal transverse diameter of uterine.
Description
Technical field
The present invention's intelligence intrauterine device (IUD) method for optimizing and system especially utilize B ultrasonic to measure the women of child-bearing age's uterus, intelligent intrauterine device (IUD) method for optimizing and system.
Background technology
The women of child-bearing age will reach the purpose of contraception, and an effective method is placement of intrauterine devices in uterine cavity (IUD).Present operational approach is: be with graduated probe to insert uterine cavity with a kind of, measure the uterus degree of depth, again according to this parameter, select IUD with doctor's experience, put in the cavity of uterus then.
It is a lot of year that this method has been continued to use, the nineties in last century also once the someone invented a kind of can be after probe inserts uterine cavity, its head portion can horizontal open device, is used to measure the transverse diameter in uterus, determines suitable IUD with two parameters.Though this method is more accurate than single radial line measurement method, because operation inconvenience, naked eyes be can't see again, so that have influenced result of use.Therefore can not promote.
Because a parameter of the cavity of uterus degree of depth has only been measured in the selection of conventional I UD, and the measurement of the degree of depth is also because the morphological differences in uterus can not determine whether arrive at the bottom of the palace, so a lot of women tend to stomachache, menstrual blood loss increase, menostaxis not to occur because of the IUD that places matches, the cycle shortens and irregular drop is hemorrhage, band is become pregnant, encircle untoward reaction such as the position moves down/comes off.
In view of this, according to clinical observation and test, if can there be easy method to measure two above geometric parameters of cavity of uterus, then can be according to the form binding data storehouse in uterus, preferred comparatively suitable model IUD.Placement IUD is more adapted to put and obtain satisfied contraceptive effect in the uterine cavity for a long time.
In fact, ultrasound diagnosis is effective and simple and feasible method.Ultrasound diagnosis can verify not only whether this women's uterus state is fit to place IUD, and can find out different uterus shapes in advance.Particularly, the measurement function that possessed of B ultrasonic can be measured the various radial line parameters in uterus easily: major diameter (being the degree of depth), transverse diameter (about footpath), thick footpath (anteroposterior diameter) etc.Utilize these parameters,, just can optimize suitable IUD model by searching database.
But interior transverse diameter is fit to place the IUD most critical of suitable dimension to whether, do not have at present by measure obtain in the reentry method and system of IUD of suitable dimension of transverse diameter, especially simple superposition is realized in the B ultrasonic device.
Summary of the invention
The present invention seeks to: a kind of intelligent intrauterine device (IUD) method for optimizing and system are provided, and preferable methods and system are carried out to intrauterine device (IUD) in the uterus that especially utilizes B ultrasonic to measure the women of child-bearing age.Promptly propose by the reentry method and system of IUD of suitable dimension of transverse diameter in measure obtaining, especially superposition is realized in the B ultrasonic device.
Technical solution of the present invention is: intelligent intrauterine device (IUD) method for optimizing, and use B ultrasonic to measure the transverse diameter Y in uterus earlier, adopt linear plan algorithm to calculate, obtain the interior transverse diameter W in uterus; And by the model of the direct corresponding selection intrauterine device of interior transverse diameter W:
W＝10.631+(0.3069±0.04)X
Or adopt B ultrasonic to measure the transverse diameter Y and the thick footpath X in uterus earlier, and adopt linear plan algorithm to calculate, especially calculate the interior transverse diameter W in uterus by following formula; And by the selection of the direct corresponding selection intrauterine device of interior transverse diameter W:
W＝7.631+(0.3069±0.03)X+(0.2077±0.02)Y
Measure by B ultrasonic based on of the present invention.Calculate the interior transverse diameter W in uterus; And by the model of the direct corresponding selection intrauterine device of interior transverse diameter W: also can pass through other algorithm, as the algorithm of various simulation algorithms, Non-Linear Programming etc., transverse diameter W size in also can obtaining simultaneously.And interior transverse diameter W size and IUD model have corresponding relation.
Intelligence intrauterine device (IUD) optimum decision system is established a software in B ultrasonic is provided with, software use B ultrasonic measure the uterus transverse diameter Y or with thick footpath X, adopt linear plan algorithm to calculate, obtain the interior transverse diameter W in uterus; And by the model of the direct corresponding selection intrauterine device of interior transverse diameter W: be about to the footpath Y that measures or place the formula (calculating) of the reckoning that software expresses, can directly export the IUD model with forming software with thick footpath X data.
The present invention intelligence intrauterine device (IUD) method for optimizing, by with the combining closely of B ultrasonic equipment, or on B ultrasonic, obtain the function of extending, by the B ultrasonic device measuring and the direct IUD type in the suitable uterus of output.Bring convenience for the contraception operation.
Characteristics of the present invention are: after adopting the inventive method, try out actual contraception in the women of child-bearing age, only use by B ultrasonic and measure, and by simple calculations selection intrauterine device (IUD), selecting to place IUD dimensionally can be not excessive or too small, only model IUD under the prerequisite that guarantees contraception, make the women stomachache can not appear, through side effect such as blood volume increase, can not occur band yet and become pregnant, encircle and move down/phenomenons such as slippage.
The specific embodiment
Embodiment 1:
Measure the transverse diameter Y and the thick footpath X in uterus, by following formula
W=7.631+0.3069X+0.2077Y calculates the interior transverse diameter W in uterus.
Consult above form again, obtain suitable IUD model.
Annotate: the row's of going up numeral is the interior transverse diameter W in uterus in the form, and following row is the pairing suitable IUD model of this size range.
Embodiment 2:
Measure the uterus major diameter Y, about footpath X (transverse diameter) and thick footpath Z, according to the formula that goes out from clinical summary in conjunction with the preferred suitable IUD model of knowledge base.
According to formula W=AX+BY+CZ+D computing parameter W, consult relevant form according to W, the IUD that corresponding selection is suitable.
Embodiment 3:
Measure the uterus major diameter Y, about footpath X (transverse diameter) and thick footpath Z, according to the formula that goes out from clinical summary in conjunction with the preferred suitable IUD model of knowledge base.
According to formula W=AX
m+ BY
n+ CZ
k+ D computing parameter W consults relevant form according to W, the IUD that corresponding selection is suitable.
Embodiment 4:
With a series of tangent planes in B ultrasonic scanning uterus and after measuring relevant parameters, adopt 3 dimension dynamic imagings on screen, to show the solid shape in uterus, and 3 the tieing up axonometric charts and carry out adaptive automatically of the shape of the IUD model that will store in advance and uterus.Thereby optimize only IUD model.
