Description
Technical field
The utility model relates to the measuring device of measuring appliance technical field more particularly to a kind of dialatation of cervical os distance and contain
There are the gloves of the measuring device.
Background technique
Pregnant woman's stages of labor just before giving birth refers to delivery of baby since just before giving birth, until the process that placental membrane is given birth to, general total yield
Journey is divided into three phases: first stage of labor since uterine contraction, gradually open greatly to 10 centimetres (cervix is opened entirely), second by cervical orifice
Stages of labor is opened from cervix entirely to delivery of baby, and third stage of labor is from delivery of baby to fetal membrane, placenta is completely exhausted out.
In the management of stages of labor, cervix 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 before 6cm using 6cm as boundary, is active period after 6cm, cervix is expanded not yet
To 6cm, it must not believe 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, improves 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 cervix 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 usually longer, by different doctors or need to help
Relieving for scholar is produced, the size of cervix usually has biggish deviation.
For the inaccuracy of cervix measurement, many hospitals and company both domestic and external are all solved attempting different method
This problem.Such as trained by utero model medical worker measure cervix standard consistency, but subjective factor still compared with
Greatly.The Descending of fetal head based on ultrasonic technique of Information Science and Technoledge School, Ji'nan University and three auspicious Medical Devices Co., Ltd.'s designs
And the automatic monitoring method and system of dilatation of cervix, but higher cost, ultrasound and a full set of software systems are relied on, it can not be clinical general
And it uses.
For another example application No. is 201710352507.7 patents of invention to disclose the measurement knot that a kind of cervix opening opens big distance
Structure, the measuring scale including two measuring pieces and between two measuring pieces, one end of measuring scale are fixed therein a measurement
On part, the other end activity of measuring scale is fixed on another described measuring piece.The invention can be convenient rapid survey and go out uterine neck
Mouth opens big distance, is not influenced by external condition, and measurement is accurate, damages to cervical tissue small.But the measurement knot of the invention
Structure can not real-time dynamic monitoring, measurement when, cannot arbitrarily shorten after stretching, cannot be retouched according to the data of real-time monitoring
State cervix shape.
Utility model content
The purpose of this utility model is that it is more accurate to propose that one kind can measure for the above-mentioned deficiency of the prior art,
