Problems solved by technology

[0005] Analysis of the reasons for the poor effect of single and double balloons on pregnant women with low cervical score: the cervical canal of adult women is about 3cm long, mainly composed of connective tissue, and also contains smooth muscle fibers, blood vessels and elastic fibers, blood vessels and elastic fibers, The process of vaginal delivery is accompanied by the shortening and softening of the cervical canal, and then the expansion process. The cervical balloon acts on the internal orifice of the cervix and the external

Abstract

The invention discloses a three-chamber cervical balloon dilator, comprising: a balloon group, a rubber tube, an injection port and a plug; the first end of the rubber tube is connected to the injection port, the second end of the rubber tube is provided with a balloon group, and the The balloon group consists of a first balloon, a second balloon and a third balloon arranged in sequence at the second end of the rubber tube, the rubber tube is composed of a protective outer tube and an injection inner tube, and the rubber tube is located at the first balloon The first fixed opening, the second fixed opening and the third fixed opening are respectively set at the second balloon and the third balloon, wherein the first fixed opening, the second fixed opening and the third fixed opening are respectively connected with the three injection inner tubes The other ends of the three injection inner tubes pass through the protective outer tube and are fixedly connected to the injection interface, and the injection interface is provided with a needle core. The present invention can improve the ability of dilating the cervix to a greater extent, and has high application value for induction of labor in pregnant women with extremely low cervical score of full-term pregnancy or induction of labor in mid-term pregnancy.

Description

technical field [0001] The invention relates to the technical field of obstetrics and gynecology medical devices, in particular to a three-chamber cervical balloon dilator. Background technique [0002] Cervical dilation balloon is a non-drug midwifery device, which can safely, naturally, and gradually dilate the cervix, and increase the success rate of labor induction. The sac continuously compresses and dilates the cervix, making it soft and shortened. The balloon in the uterine cavity can expand the uterine cavity, promote the release of oxytocin from the posterior pituitary gland, and induce uterine contractions; The endogenous prostaglandins in the cervix are synthesized and released, causing uterine contractions and promoting the softening and maturation of the cervix. Ripening and dilating the cervix is ​​accomplished by the balloon providing a gentle, long-lasting dilating force at the internal and external os of the cervix, with obvious advantages. [0003] Curre...
