Description
Technical field
The present invention relates to a kind of measuring appliance, specifically a kind of opening of the cervix opens the measurement structure of big distance.
Background technology
The dilatation of cervical os be pregnant woman just before giving birth when uterus rule uterine contraction, uterus muscle and the surrounding for pulling internal cervical orifice be fine
Dimension, canal of uterine cervix gradually shorten until disappearing.The external os of vervix is antenatal only to hold a finger tip size, with progress of labor cervix outside
Mouth is expanded to 10 centimeters of diameter, allows mature fetal head to pass through.
In the management of stages of labor, palace mouth measurement is extremely critical step, directly affects judgement and processing to stages of labor.
In the newest stages of labor management of obstetrics, it is incubation period using 6cm as boundary, before 6cm, is active period after 6cm, palace mouth is not expanded also
To 6cm, it is impossible to think that puerpera has come into active period, for obstetrician and midwife, dilatation of cervix to which kind of journey
Degree is extremely important into active period at last, can reduce unnecessary Intervention in the stages of labor, improve female tire final result, in addition, understanding stages of labor not
Also extremely important with stage dilatation of cervix speed, accurate understanding stages of labor different phase dilatation of cervix speed is extremely important, so as to more
Good management stages of labor, the extension and stagnation of Accurate Diagnosis active period.The measurement of palace mouth relies primarily on manual measurement, subjectivity at present
Relatively strong, accuracy is poor, and different people measurement standard is different, and stages of labor is generally longer, need to pass through the friendship of different doctors or midwife
Succeed, the size of palace mouth usually has larger deviation.
For the inaccuracy of palace mouth measurement, many hospitals and company both domestic and external solve all attempting different methods
This problem.Such as by utero model come train medical worker measure palace mouth standard consistency, but subjective factor still compared with
Greatly.Information Science and Technoledge School of Ji'nan University and the Descending of fetal head based on ultrasonic technique of three auspicious Medical Devices Co., Ltd.'s designs
And the automatic monitoring method and system of dilatation of cervix, but cost is higher, relies on ultrasonic and a full set of software systems, and can not be clinical general
And use.
And for example inner measurer for pelvises of expectant mothers disclosed in Patent No. CN202288292U, including it is hinged on one by hinge
The X-shaped measuring staff risen, elastic fingers are respectively fixed with the top body of rod of the measuring staff；The lower end of the measuring staff is provided with measurement institute
State the survey chi of measuring staff extended distance.Fixture is provided with measuring staff on the survey chi or at hinge.Fixture be with palm or
The elastic webbing that wrist sizes adapt to；Fixture can also be adhesive tape.Can be big with the opening of accurate measurement Later pregnant women opening of the cervix
The indexs such as small and Descending of fetal head distance, the width of ischial spine, ligamentum sacrotuberosum width, standard is provided for the scheme of delivering a child of doctor
Firmly believe breath.But this is theoretically only feasible, does not have the value used actually.Because measure uterus opening
Prerequisite is that two finger middle fingers and forefinger are combined into vagina, but this two states for referring to merging can become palm
Shape, while vagina also has specific physiological bending angle, then how the measuring appliance for the X-shape being fixed on palm becomes to realize
Shape, it can not ensure, in the accuracy of the X opening angles of palm rear end, to cause measurement error larger again after deformation.
The content of the invention
The purpose of the present invention is to overcome existing the defects of measuring uterus opening apparatus, there is provided a kind of opening of the cervix opens big distance
Measurement structure, can conveniently, accurately carry out uterus openings of sizes measurement.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of opening of the cervix opens the measurement knot of big distance
Structure, including two measuring pieces and the measuring scale between described two measuring pieces, one end of the measuring scale are fixed therein
On one measuring piece, the other end activity of the measuring scale is fixed on another described measuring piece.
Above-mentioned technical proposal, measurement is completed by two measuring scales between measuring piece and measuring piece, not by palm deformation
And the influence of the specific physiological bending angle of vagina, measuring piece are set on finger, maximum distance is between two measuring pieces
For openings of sizes.
Measuring piece is preferably the structure of ring-type, and finger is arranged conveniently, and the diameter of the measuring piece of ring-type adds the quarter of measuring scale
Degree, the as size of uterus opening.
And the size of preferably ring-type is adjustable, meet the finger of different thicknesses.
But in operation, a problem can be encountered again, and ring-type size is adjustable, bad for the diameter of the measuring piece of ring-type
Fixed, the diameter of ring-type measuring piece often changes once, and the diameter of measuring piece is required for remeasuring, cumbersome.
Preferably, the measuring piece is the cyclic structure that diameter is fixed, diameter is provided with cyclic structure
Adjustable finger ring.Like this, it can not only meet the finger of different thicknesses, and diameter, diameter need not be measured every time
The constant measuring piece of size, even if the finger of different thicknesses goes to measure, it is not required that recalculate diameter.
Preferably, be provided with fixing hole on one of them described measuring piece, one end of the measuring scale is fixed on described
Fixing hole；Regulating block is set on another described measuring piece, adjustment hole is offered on regulating block, the other end of the measuring scale is worn
The adjustment hole is crossed, the adjustment hole is fixed in the measuring piece activity.
Preferably, being provided with regulation elasticity piece in the adjustment hole, lock tooth is provided with the regulation elasticity piece, it is described
The teeth groove coordinated with the lock tooth is provided with the inside of measuring piece.
Measuring scale can drive measuring piece with finger and extend and measure, and by locking tooth and teeth groove, measuring scale is one
Determine to be drawn out under dynamics, stretched measuring scale will not bounce back, and ensure the degree of accuracy of measurement.
Preferably, the teeth groove wall is obliquely installed, the advance of measuring scale when the incline direction of the teeth groove wall and measurement
In the opposite direction, the incline direction of the lock tooth is opposite with the incline direction of the teeth groove wall.
Preferably, being provided with the adjusting knob extended to outside the adjustment hole on the regulation elasticity piece, tune can be passed through
Button is saved, regulation elasticity piece is increased with adjusting the distance between hole wall, so as to which after measurement is good, measuring scale can be retracted, and disappear
For measuring next time after poison.
Preferably, guide groove is provided with the outside of the measuring piece, the cell body of the guide groove and the adjustment hole phase
It is logical；The measuring scale winding is located at the guide groove, so designs, and measuring scale more smoothly can be pulled out and returned out of adjustment hole
Move back.
Preferably, the measuring piece is the cyclic structure that two free ends are not closed, one of free end is positioned at another
The inner side of one free end.Convenient regulation diameter.
Preferably, being provided with graduation mark on the inside of the measuring piece, even if the diameter of measuring piece needs constantly to change, lead to
The size of diameter can quickly be obtained by crossing the graduation mark of inner side, convenient to calculate.
By implementing above-mentioned technical proposal, what the present invention can measure opening of the cervix with fast and easy opens big distance, not by outer
The influence of boundary's condition, measurement is accurate, cervical tissue is damaged small.
