Abstract

The invention discloses an automatic coating device of surface coatings of a medical catheter. The automatic coating device comprises five assemblies which are in sequential series connection, wherein the assemblies comprise racks; and servo mechanisms and moving platforms are mounted inside the racks. The coating operation of the coatings is achieved through sequentially carrying out S1, pre-coating preparation, S2, pre-coating cleaning technology treatment, S3, coating technology treatment, and S4, post-coating final cleaning technology treatment on the catheter. According to the automatic device used for coating the surfaces of the medical catheter with the coatings based on the dip coating principle, the problems that in dip coating of the medical catheter, a liquid accumulates at the head ends of instruments and the coating is relatively thick are solved, the pre-coating cleaning and post-coating final cleaning technologies of dip coating of the medical catheter are integrated, the production efficiency is greatly improved, and the quality of the coatings adhering to the inner and outer surfaces of the catheter is improved.

Description

technical field [0001] The invention belongs to the technical field of medical apparatus and equipment, and relates to an automatic coating device and a coating method for the surface coating of a medical catheter. Background technique [0002] The advancement of medical technology and the large-scale application of non-invasive and minimally invasive surgery have made medical catheters, guide wires, stents, etc. with hydrophilic and ultra-slippery, antibacterial, anticoagulant, and drug-eluting effects to play an irreplaceable role in clinical practice. These functions are achieved on the surface of medical devices through medical coatings, with special coating equipment and coating methods. Commonly used coatings include dip coating, spray coating, spin coating, and electrochemical coating. Spraying, spin coating and electrochemical coating are often used for the coating of stents and reticular devices with complex structures. The equipment has high precision, complex str...
