Document Type and Number:
WIPO Patent Application WO/2020/258945
Kind Code:
A1
Abstract:
A medical tube preparation method and a medical tube prepared using same. The preparation method comprises dispersing polytetrafluoroethylene in a polyimide precursor solution, and modifying the surface of polyimide by using the polytetrafluoroethylene. On the one hand, the friction coefficient of the polyimide material is lowered, and the surface lubricity of the medical tube is improved, thereby reducing the surface resistance of the medical tube, decreasing the possibility of damage to human blood vessels during the process of introducing the medical tube into a human body, and facilitating the push of drugs or instruments into the human body; on the other hand, the difficulty in separation due to the action of the tube and a forming base during tube forming is also avoided.
