This invention is about a process for painting drug elution vas internal support and the painting apparatus. It is a process for painting cardiovascular support and the painting apparatus. This invention solves the problem of heterogeneous painting and great material consumption in current support. The painting preparation processes mainly contain cleaning, drying and spraying to prepare drug coating. The painting apparatus mainly contain: support, nozzle, solution bottle, plastic hose, flow instrument, high-pressure tank, nozzle, ultrasonic atomizer, adjustable rotary table and flume. The downside of the support strut connects with the adjustable rotary table; the solution bottle connects with high-pressure tank by the flow instrument, the ultrasonic atomizer, whose top connects with the solution bottle, is installed in the flume. The uniform drug coating is formed by painting ultrasonic nebulized aerosol fogdrop on the surface of the support of certain movement state. This invention can not only paint heterogeneously and decrease surface roughness of support, but also can greatly save painting material. |
