Problems solved by technology

However, there are some technical defects in these existing technologies. For example, the vast majority of intrauterine anti-adhesion materials and balloon stents do not have antibacterial and anti-infection designs, lack active ingredients that promote endometrial repair and regeneration, and prevent intrauterine adhesions. Devices and instruments lack of visibility devices, etc.

Abstract

The invention relates to a balloon uterine stent for preventing adhesion of a uterine cavity. The stent consists of a triangular balloon stent (1), a catheter (2), a one-way valve (3) and a liquid discharge cavity (7).The balloon uterine stent solves the problem that a composite functional coating coats the surface of fluorosilicone rubber which is difficult to coat. The three functions of development, active function and infection resistance are organically combined, so that the anti-adhesion effect of the balloon uterine stent for preventing adhesion of a uterine cavity is greatly improved,and the stent has very important application prospect.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical equipment. More specifically, the present invention relates to a balloon uterine stent for preventing adhesions in the uterine cavity. 【Background technique】 [0002] Intrauterine adhesions (IUA), also known as Asherman syndrome, are usually endometrial injuries caused by intrauterine operations, radiation exposure, gynecological infections and other factors. Although intrauterine adhesions are not malignant diseases, they have a huge impact on patients and their lives, such as abnormal menstruation, periodic severe abdominal pain and reproductive dysfunction, which further affect the effect of assisted reproductive technology. [0003] At present, the clinical methods to prevent re-adhesion are mainly drug therapy, physical barrier and endometrial stem cell therapy. Among them, the physical barrier method uses mechanical stretching to fully stretch the wall of the uterine cavity, thereby redu...
