Inductive uterine slow release system

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.
