Description

Palace mouth measurer

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to palace mouth caliber.

Background

The cervical canal of a woman is a muscular canal with the length of about 2 centimeters, is externally connected with a vagina and is internally connected with a uterine cavity. When the pregnant woman is in delivery, the uterus contracts regularly to pull the uterine muscle and the surrounding fibers of the internal cervix, and the amniotic fluid sac before the fetal presenting part is wedge-shaped, so that the internal cervix expands upwards and outwards, and the cervical canal is gradually shortened until the cervical canal disappears. The external opening of the cervix is usually only as large as one fingertip, and can be expanded to a diameter of 10 cm along with the progress of labor process, so that the fetal head of the term can pass through, and the process is the expansion of the cervical opening.

The process of opening the uterine orifice is slow, and the cervix is usually gradually flattened only in week 2 after 9 months of pregnancy. The cervix uteri can stretch to 10 cm at birth of a baby, is slow at the beginning, and takes 8 hours on average from the point of delivery to the opening of the uterine cavity with the size of cm, and takes 4 hours on average from the opening of the uterine cavity with the size of 6 cm to the opening of the uterine cavity with the size of 10 cm. Indicating that the uterine orifice is opened to 6 cm in the active period of childbirth, the cervix becomes soft and thin and has high elasticity, and the interval between every two uterine contractions is 2-3 cm. The uterine orifice will gradually open up with regular contraction of the uterus immediately after parturition. The large degree of opening of the uterine opening divides the first phase of labor into two phases, namely a latent phase and an active phase. The incubation period is from regular uterine contraction to the opening of the uterine cavity being 6 cm in size, and the active period is the period of the opening of the uterine cavity being 6-10 cm in size.

The obstetrical department judges the labor process of the pregnant woman, the expansion of the cervical orifice is an important index, but at present, no accurate instrument monitors the expansion degree of the cervical orifice, and the expansion degree of the cervical orifice is estimated by means of hand feeling only by means of finger probing of medical staff. Such exploration is clearly lack of accuracy, resulting in a medical practitioner's judgment of labor that is prone to drift.

SUMMERY OF THE UTILITY MODEL
