Antibacterial intervention medical apparatus

Abstract

The invention discloses an antibacterial interventional medical device, which comprises a medical device body, a coating layer, a nano-coating layer and a drug-carrying layer sequentially from the inside to the outside, and the coating layer is sutured and fixed on a medical On the device, the nano-coating is made by uniformly attaching nano-scale graphene on the coating layer, and the drug-carrying layer is made by adding styrene-isobutylene di-block or tri-block copolymer containing sulfonic acid groups It is prepared by coating the nano-coating in small pieces after adding medicine in the middle, and the thickness of the coating layer, the nano-coating and the drug-carrying layer are all 0.7-0.8mm, and the invention is convenient to use and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, 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 ...
