Abstract

An embodiment of the present application provides a drainage tube and a drainage device, which relates to the technical field of medical devices. The drainage tube includes a drainage portion, a porous loose structure and a granulation barrier structure. The drainage portion has a first drainage channel, and the drainage portion is provided with a first drainage opening in communication with the first drainage channel. The drainage portion is covered with the porous loose structure. The porous loose structure is covered with the granulation barrier structure. The granulation barrier structure has a second drainage opening, wherein the second drainage opening, the porous loose structure, the first drainage opening and the first drainage channel are in communication. With the provision of a granulation barrier structure, while the requirements of negative pressure adsorption can be met, the granulation is prevented from growing into the porous loose structure, thereby reducing the bleeding of granulation tissue and improving the therapeutic effect of negative pressure drainage.
