  • Publication number: 20190314618
    Abstract: A double-layered drainage tube, composed of an inner layer and an outer layer closely attached to each other is shown. The inner layer is made of a hydrophobic material, and the outer layer is made of a human biocompatible material. Liquids do not adhere to the inner wall, thereby preventing tube clogging. The outer wall is soft and elastic, has a smooth surface, and has a good compatibility with body tissues without causing inflammation. Moreover, in the case where there is no middle layer of a stainless steel wire, the diameter and cost of an outer tube are reduced and the insertion difficulty is reduced, and the inner diameter of the drainage tube is increased, and the effective drainage cross-sectional area of the drainage tube is increased.
