Abstract

The invention provides a hemodialyzer and a hemodialysis system applying the hemodialyzer. The hemodialyzer comprises a tube body, a hollow fiber membrane arranged in the tube body; a first cover body arranged at the blood inlet end in the tube body; a second cover body arranged at the bleeding end in the tube body, wherein the blood inlet end is opposite to the bleeding end; and a hydrophilic material layer formed on the inner surface of the first cover body and / or the inner surface of the second cover body. The hydrophilic material layer is formed on the inner surface of the cover body, so that substances such as cells and proteins in blood are not easy to attach to the inner surface of the cover body. In addition, a hydrophilic material layer can be formed on the inner surface of the blood pipeline connected to the cover body, so that substances such as cells and proteins in the blood are not easy to attach to the inner surface of the blood pipeline. Therefore, the blood coagulation phenomenon can be avoided in the hemodialysis process, and the safety of hemodialysis is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hemodialyzer and a hemodialysis system using the same. Background technique [0002] Currently, hemodialyzers are widely used for blood purification of patients with kidney disease. The hemodialyzer comprises a tube body, a hollow fiber membrane and two covers, wherein the hollow fiber membrane is arranged in the tube body, and the covers are arranged at two opposite ends of the tube body. When the hemodialyzer is used for hemodialysis, the blood flows into the tube body from the cover set at the blood inlet end, passes through the hollow fiber membrane, and then flows out of the tube body through the cover set at the bleeding end. [0003] Generally, the cover is made of engineering plastics such as polycarbonate (PC) or polypropylene (PP). In the process of hemodialysis, substances such as cells and proteins in the blood are easily attached to the inner surface of the cover, ...
