Embodiment Construction

[0020] The present invention is further analyzed below in conjunction with accompanying drawing.

[0021] The inductive uterine cavity sustained-release system of the present invention comprises a uterine-shaped elastic balloon stent 1, a sustained-release drug film 2, a catheter 3, and a one-way inflation valve 4; the uterine-shaped elastic balloon stent 1 is a hollow isosceles triangle structure Body, the waist of this isosceles triangle is 3.5cm, and the base is 3cm; There are a plurality of annular scales 5, the distance between the first annular scale 5-1 and the top angle of the palace-shaped elastic balloon support 1 is 1 cm, and the distance between two adjacent annular scales 5 is 1 cm; the one-way inflation valve 4 It includes an inflation valve and a pressure sensor. The pressure sensor is arranged at one end of the one-way inflation valve 4 connected to the catheter 3 for sensing the pressure of the palace-shaped elastic balloon stent 1. The inflation valve is arra...

Abstract

The invention discloses an inductive uterine slow release system. The incidence of uterine adhesion after an induced abortion operation is high, the re-adhesion is serious after a uterine adhesion operation, and no good solution is available at present. The system comprises a uterus-shaped elastic balloon stent, a slow release drug film, a catheter and a one-way inflation valve, wherein the uterus-shaped elastic balloon stent is a hollow isosceles triangle structural body; waists of the isosceles triangle are 3.5cm; the bottom edge of the isosceles triangle is 3cm; one end of the catheter is connected and communicated with the vertex angle end of the uterus-shaped elastic balloon stent; the other end of the catheter is connected with the one-way inflation valve; a plurality of annular scales are arranged on the outer side face of one end, close to the uterus-shaped elastic balloon stent, of the catheter; and the one-way inflation valve comprises an inflation valve and a pressure sensor. The uterus-shaped elastic balloon stent is coated with the slow release drug film, and the slow release drug film is made of fibrin glue and contains a slow release drug. The system is simple in structure and easy to operate, does not injure a uterine cavity easily, and can effectively avoid the uterine adhesion.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to an inductive uterine cavity sustained-release system, which is used for artificial abortion, uterine cavity adhesion separation or resection, uterine mediastinectomy, endometrial polypectomy and uterine deformity plastic surgery Placed after various uterine surgery. Background technique [0002] With the change of lifestyle and the influence of social thoughts, more and more women have experienced one or even multiple unwanted pregnancies before giving birth. As the most widely used clinical method to terminate unwanted pregnancy, induced abortion has been generally accepted by women all over the world. According to the World Health Organization, there are 25-55 million abortions every year in the world. The number of people involved in artificial abortion is large and the scope is wide. It has become a global social problem and an important public health problem. According t...
