Description
Technical field
This application involves gynicologycal medical instrument fields, and in particular to a kind of syringe-type cervical dilatation size measuring instrument.
Background technique
Sub- cervix is that uterus is connected to the uterus part of vagina, and the shape of uterine neck is cylindric or coniform, and
And with the canal of uterine cervix across it, canal of uterine cervix, which has, to be opened to the collar extension of vaginal canal and is opened to the internal orifice of uterine cavity.In throe
In birth process, cervix is the channel that fetus enters that vaginal canal is passed through from uterine cavity.
Non- pregnancy period and antenatal cervical canal are in closed state, under childbirth phase or pathologic condition, cervical dilatation, and amnion
Capsule reaches even prominent cervical orifice along cervical canal, and fetus is given birth to along cervical canal to intravaginal.Cervical dilatation size, i.e., it is sub
The diameter of cervical orifice, when term birth are the important indicators of observation, whether smooth directly react progress of labor；Cervical cempetence is not
Full-time, cervix opening is opened ahead of time, and degrees of expansion and the prognosis after operative treatment are obviously related, and expanded dimension is bigger, treatment effect
Fruit is poorer, currently, digital examination and visual examination method are the standard methods that clinician is used to measure cervix diameter.What digital examination referred to
Be: glove hand is protruded into vagina and is touched or detected cervix and cervix using middle finger and index finger by clinician
Mouthful.Fingertip touch simultaneously finds cervical orifice, then stretchs out until finger tip contacts to cervical orifice are to side wall, the finger tip stretched out
Distance is equivalent to cervix diameter, i.e. cervical dilatation size.And visual examination rule is to line-of-sight observation palace after specula peeps out vagina
The size of neck mouth expansion.
The distance of this two methods measurement is influenced greatly, to be easy to appear artificial by the habit and clinical experience that check doctor
Error in judgement, influences doctor's subsequent operation, serious or even endanger patient and neonate life.
Summary of the invention
The purpose of the present invention is to provide a kind of syringe-type cervical dilatation size measuring instruments, objective can directly measure palace
Neck expands size, reduces the fault that manual operation occurs, avoids the risk of above-mentioned appearance.
The technical solution adopted by the present invention is that a kind of syringe-type cervical dilatation size measuring instrument, including bobbin, abutting bobbin
Rubber plug, the rubber plug of inner wall connect the core bar stretched out from bobbin rear end, the front end of bobbin is connected to swelling part；The rubber plug,
Inside one sealing inner cavity of formation of bobbin, swelling part；The core bar can drive rubber plug to move back and forth with respect to before and after bobbin, core
The back segment of bar is additionally provided with the scale of axial alignment；When the core bar is moved along, swelling part is expanded to contrary two sides；
The core bar moves backward when, swelling part is shunk；The outer diameter of swelling part is corresponding with scale.
Preferably, the swelling part is expandable sphere.Swelling part is selected as expandable sphere, this structure
It is the simplest, it makes more convenient.
Preferably, the swelling part is one section of T-type pipe being connected to bobbin, which includes one section of vertical arm and two sections
Transverse arm, wherein vertical arm is connected to bobbin, and two sections of transverse arms are connected to from different expansion devices respectively.The T-type pipe of setting is easy to tear open
It unloads, and the transverse arm of itself has certain length, it is only necessary to push some distances of core bar that can measure biggish cervix
The diameter of mouth.
Specifically, the expansion device is expandable sphere.Expansion device is expandable sphere, and production is more simple
It is single, it is easy to implement.
Preferably, the syringe-type cervical dilatation size measuring instrument is made of plastics.More using syringe-type made of plastics
It is hygienic reliable.
Preferably, the sealing inner cavity is provided with liquid.In workflow, workflow is artificially by pushing core
Bar, make rubber plug by bobbin gas or liquid be pressed into expansion device, therefore expansion device expands until touch cervix
The inner sidewall of mouth, the scale that observation core bar promotes, which represents the gas of indentation expansion device or the volume of liquid, with this
Infer the degree that expansion device is expanded to two opposite directions, measures, and gas phase is easy to be reduced by compression for liquid
Volume influences final judging result.
Compared with prior art, the present invention have it is following the utility model has the advantages that
Workflow of the invention is as follows: doctor holds with a firm grip the syringe-type cervical dilatation size measuring instrument, protrudes into patient's vagina,
Until the instrument front end portion is protruded into cervical orifice, core bar is pushed, core bar is swollen by gas in sealing space or liquid indentation
Among swollen device, until inner sidewall of the expansion device expansion contact to cervical orifice, core bar promote more, the expansion of expansion device
Degree is bigger, observes and records the scale of core bar back segment, with the scale extrapolate expansion device contact inner sidewall both ends away from
From obtaining the diameter of cervical orifice, as cervical dilatation size.The present invention provides one kind, can directly to measure cervical dilatation big
Small instrument, the result objective reality which measures, is not influenced by subjective factor, greatly reduces manual operation appearance
Fault, it is easy to implement.
