Abstract

The invention discloses an energy-saving and environment-friendly coating method for a medicine coating on an implantable medical apparatus and belongs to the technical field of energy saving and environmental friendliness. The method specifically comprises the following steps that S1, the medical apparatus is soaked in a cleaning agent to remove oil stains, rust spots, oxidized scales and acid-base residues on the surface of the medical apparatus; S2, a chemical is heated and evaporated under the vacuum condition so that a large number of atoms and molecules in the chemical can be gasified and sublimated; S3, the medical apparatus is baked, and is put in the chemical sublimating atmosphere for ion bombardment after the surface temperature of the medical apparatus rises; S4, the atoms andthe molecules in the chemical settle on the surface of the medical apparatus to form the medicine coating; and S5, afterwards the medicine coating is cooled to be solidified. The medicine coating hashigh bonding force with the surface of a medical apparatus body, is uniform and compact, has a good winding plating property under the negative bias action, can reduce the rejection reaction of organisms to implants, and has high abrasion resistance at the same time, and the service life of the implants is prolonged.

Description

technical field [0001] The invention discloses an energy-saving and environment-friendly coating method for a drug coating on an implanted medical device, and specifically belongs to the technical field of energy conservation and environment protection. Background technique [0002] The vast majority of medical devices are made of metal, and there are problems such as corrosion, longevity and human rejection during use. The layer on the implanted access device is mainly orthopedic, and the orthopedic implant material is mainly metal or ceramic, which is incompatible with tissues and organs and is prone to wear and tear. For this reason, we proposed an energy-saving and environment-friendly coating method for drug coating on implanted medical devices and put it into use to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an energy-saving and environment-friendly coating method for drug coating on implanted medic...
