Cervical dilatation balloon catheter

Abstract

The invention relates to the technical field of medical instruments, and discloses a cervical dilatation balloon catheter. According to the cervical dilatation balloon catheter, tablets are placed in a medicine storage cavity by rotating a head end, the head end is tightened, lubricating physiological liquid medicine is injected into a sealing injection ring, the lubricating physiological liquid medicine dissolves the tablets into particles and flows out of the medicine outlet holes, so that the inner wall of the vagina of a puerpera is lubricated, meanwhile, the aims of stopping bleeding and suppressing pain are achieved, and comfort is improved; According to the cervical dilatation balloon catheter, a first balloon and a second balloon are filled with normal saline and placed on the inner opening of the cervix uteri, mild mechanical expansion force is generated on the lower uterine segment and the cervix uteri, disappearance of the lower uterine segment and dilatation of the uterine opening are promoted, meanwhile, secretion of endogenous prostaglandin is stimulated through separation and stripping of a fetal membrane, so that the cervix uteri of the puerpera is gradually expanded unconsciously, and accordingly nerves reflect, so that nerve tracts of posterior pituitary release oxytocin, the oxytocin level in maternal blood circulation is increased, uterus contraction is promoted to be continuously enhanced, then labor induction is successful, and the operation efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and is specifically a cervical expansion balloon catheter. Background technique [0002] With the understanding of the public, this natural, healthy, scientific childbirth method is increasingly being recognized and persisted in maternal and his family. During the clinical process, the maternal needs to achieve certain production conditions before production, More common, the uterine mouth needs to open to about ten refers to the width. Before the width is not reached, the nurse will repeatedly check until the predetermined width will only be licensed. The induction is a conventional surgery taken by pregnant women indicative of pregnancy without catholic production. If the pregnancy is not terminated in advance, there will be an expiration pregnancy, leading to fetal mature disorders, fetal distress, neonatal asphyxia, etc., which give great adverse effects to maternal and child healt...
