Description

Cervical balloon for induced labor

Technical Field

The application relates to a cervical balloon, in particular to a cervical balloon for induced labor.

Background

Induction of labor refers to the termination of pregnancy by artificial uterine contraction induced after 12 weeks of gestation due to maternal or fetal reasons. According to the gestational week during induction of labor, the induction of labor can be divided into midterm induction of labor (14-28 weeks) and late term induction of labor (28 weeks later), and whether the induction of labor is successful or not is related to various factors. Cervical maturity is an important factor in determining the success or failure of labor induction. The cervix is immature and induction of labor is often not successful. The ideal method for promoting cervical ripening is similar to the natural ripening process of cervical ripening people, does not cause excessive uterine contraction, does not influence uterine blood flow, and does not endanger the safety of fetuses and mothers. There are several methods for promoting cervical ripening, and to date there is no very perfect and very effective method. The currently used methods are classified into non-drug and drug types.

The cervix uteri of the pregnant woman induced to give birth in late pregnancy is relatively soft, has large erosion-shaped surface, is easy to bleed when being touched, and presses the neck after being expanded by the permeable expansion rod to break water or guide bleeding to pass through the cervix uteri to be difficult to flow out. Therefore, a cervical balloon for induction of labor is proposed to address the above problems.
