Antibacterial intervention medical instrument

Abstract

The invention discloses an antibacterial intervention medical instrument comprising a medical instrument body, a film covering layer, a nanometer coating layer and a medicine carrying layer from inside to outside. Polyether urethane material is sewed and fixed on the medical instrument for form the film covering layer; nano-silver water solution is evenly coated on the film covering layer to form the nanometer coating layer; and medicine is added to styrene-isobutylene diblock or triblock copolymer and then divided into small blocks to be coated on the nanometer coating layer to form the medicine carrying layer. The antibacterial intervention medical instrument employs a special structure, in which the film covering layer is made from non-transparent high-polymer material having biocompatibility and the surface medicine carrying layer is polymer containing sulfo group; thrombus can be prevented and postoperative complications can be reduced; with the medicine carried with bioactivity, the medicine can be controlled to be slowly released and curing effect can be enhanced; meanwhile, antibacterial effect of the medical instrument is guaranteed by the use of the nanometer coating layer; bacterial infectious diseases caused by the medical instrument can be reduced; and patient pains can be lowered.

Description

technical field [0001] The invention relates to the field of medical device processing, in particular to an antibacterial interventional medical device. Background technique [0002] Interventional medical devices are emerging medical device technologies in the past two decades. They play a very important role in reducing trauma to patients and improving disease treatment effects. However, at the same time, it cannot be ignored that bacterial infectious diseases produced by medical devices have become One of the important issues that clinical departments pay attention to is not only the high incidence rate, but more importantly, after infection, it will cause poor healing and even lead to death. Therefore, while continuously improving interventional medical devices, we must also pay attention to antibacterial medical devices development applications. The invention introduces an antibacterial interventional medical device, which adopts a special structure, the coating layer ...
