Project Description

Ultrasonic Vascular Stent Spraying

Vascular stent refers to the expansion of the shape of the lumen balloon, placed in the lesion within the stent in order to support the narrow occlusion of blood vessels, reduce vascular elastic retraction and reshaping, to maintain lumen blood flow purposes.
Ultrasonic Vascular Stent Spraying - CHEERSONIC Ultrasonic Atomizing
CHEERSONIC Ultrasonic Atomizing Spraying Equipment is a high-precision ultrasonic atomizing spraying system specially designed for the surface treatment of micro instruments. It is dedicated to the combination of ultrasonic atomizing spraying technology and coating preparation of vascular scaffolds to guide the process development and optimize the coating quality purpose. CHEERSONIC ultrasound in accordance with the physical mathematical modeling, fluid dynamics simulation, experimental detection and analysis, process development and application of the route to study and eventually successfully developed for vascular stent ultrasonic medical spraying equipment.
Ultrasonic Vascular Stent Spraying - CHEERSONIC Ultrasonic Atomizing
CHEERSONIC ultrasonic optimization of the process parameters and found that ultrasonic frequency of this parameter is the main factor affecting the quality of the coating. Based on the optimized parameters, we constantly improve the ultrasonic frequency to achieve the change of ultrasonic atomizing spray to ultrasonic medical spraying. The experiment of the preparation of the stent coating verifies that the ultrasonic medical spraying equipment completely eliminates common thick edges, bridges, bumps and particles Equal issues. The surface roughness decreased from 6.35nm before optimization to 1.72nm, the coating quality was significantly improved. In addition, the incremental coating test results showed that the coating quality deviation of multiple spray coating was about 10μg in the same stent, and the optimized process had good reliability Sexual and stability.
