Ultrasonic Drug Polymer Coating Stent Equipment Precision Spraying Atomization
Description:
Ultrasonic drug polymer stent coating is a method of using ultrasonic technology to form a polymer coating on the surface of the stent and embed drugs into it. This coating combines the advantages of polymer materials and drug release to improve the effectiveness of vascular intervention therapy.
The advantage of ultrasonic drug polymer stent coating is that it can achieve sustained drug release and uniform coverage of polymer coating. Polymer materials provide drug carriers that can control the release rate and duration of drugs, thereby improving treatment outcomes. Ultrasonic technology can enhance the adhesion and uniformity of coatings, further improving the reliability of treatment effects.

The preparation process of ultrasonic drug polymer stent coating usually includes the following steps:
1. Prepare bracket: Select the appropriate bracket and ensure its surface is clean and free of impurities.
2. Preparation of polymer solution: Select suitable polymer materials and dissolve them in appropriate solvents to form a polymer solution. The selection of polymers should consider factors such as their biocompatibility, adhesion, and drug loading capacity.
3. Polymer coating formation: Immerse the scaffold into a polymer solution to fully wet its surface. Then, ultrasonic techniques such as ultrasonic spraying or ultrasonic vibration are used to promote the formation of a uniform coating of the polymer on the surface of the scaffold. The energy of ultrasound can improve the adhesion and uniformity of coatings.
4. Drug embedding: Embedding the desired drug into the polymer matrix while forming the polymer coating. Drugs can be drug molecules dissolved in polymer solutions, as well as drug particles or nanoparticles.
5. Drying and Curing: After completing the coating and drug insertion, the scaffold needs to be dried and cured to improve the stability and adhesion of the coating.
