Medicine coating equipment with medicine balloons

Abstract

The invention relates to the technical field of medical apparatuses and instruments and discloses medicine coating equipment with medicine balloons. The equipment includes a spraying chamber, an ultrasound generating device, a medicine supply device, an air loading device, a clamping device used for clamping to-be-coated balloons and a recovery device; the clamping device comprises a first ballooncatheter clamp and a second balloon catheter clamp, and the second balloon catheter clamp can move relative to the first balloon catheter clamp; the air loading device consists of an air loading pipecommunicated with an air source, a drying mechanism, a doping mechanism and a heating mechanism, wherein the drying mechanism, the doping mechanism and the heating mechanism are arranged on the air loading pipe in sequence; the ultrasound generating device comprises an ultrasound generator and an ultrasound sprayer connected with the ultrasound generator; the ultrasound sprayer is connected withthe medicine supply device and the air loading pipe separately; medicine of the medicine supply device is atomized by ultrasonic waves generated by the ultrasound generator and then sprayed onto the to-be-coated balloons by the air loading pipe. Medicine coatings generated by the medicine coating equipment with the medicine balloons have high quality and high production efficiency, and the surfaces of core shaft catheters of the to-be-coated balloons cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug balloon drug applicator. Background technique [0002] In recent years, a variety of interventional or implantable medical devices loaded with drug coatings have been developed for various causes of intravascular restenosis. It mainly includes drug balloons and drug-eluting stents. The surface of this type of device is uniformly coated with polymer, and a layer of therapeutic drug coating is added to the polymer coating. The drug-coated balloon or After the stent enters the blood vessel, the drug is gradually and slowly released, so as to achieve the purpose of treating and preventing restenosis in the blood vessel. At present, more and more people pay attention to and devote themselves to the research of drug-eluting stents. Compared with drug-eluting stents, drug-eluting stents do not need to be left in the human body, which greatly reduces various risks. [00...
