Medical tubes and process for producing the same.

摘要

Disclosed is a medical tube comprising a mono-layer medical tube comprising a high molecular compound, wherein the inner texture of a tube wall constituting the tube is porous and no skin layer is present on the inner face of the tube wall. Disclosed is also a process for producing a medical tube, comprising thrusting forward a core rod having a round cross-section and made of a rigid body from a circular orifice to extrude a solution of a high molecular compound from a gap slit defined between the orifice and the core rod in such a manner that the solution is spread over the whole surface of the core rod, and leading the core rod in a solidifying medium to solidify the high molecular compound around the core rod, followed by taking out the core rod. The medical tubes of this invention or the medical tubes produced by the present process has excellent compatibility with blood, particularly is suitable for an artficial blood vessel which is required to have excellent long term patency.
