Function of Ultrasonic Drug Eluting Stent Sprayer
The Ultrasonic Drug Eluting Stent Sprayer has the following main functions:
1. Precise drug spraying
- Achieve uniform coating: Ultrasonic spraying technology can produce very fine and uniform droplets, which can evenly cover the surface of the stent to form a drug coating with uniform thickness. This is crucial for drug eluting stents, because a uniform coating can ensure that the drug is released at a stable rate after stent implantation, avoiding the situation where the local drug concentration is too high or too low, thereby improving the treatment effect and reducing the risk of side effects.
- Control coating thickness: By adjusting the spraying parameters, such as ultrasonic frequency, spraying pressure, spraying time, etc., the ultrasonic sprayer can accurately control the thickness of the drug coating. Different diseases and patients may require different thicknesses of drug coating to achieve the best treatment effect. For example, for some severe cases of vascular stenosis, a thicker drug coating may be required to provide a higher drug dose, while for milder cases, a thinner coating can be used to reduce the side effects of the drug.
2. Improve drug binding force
- Enhance the adhesion between drugs and stents: During the ultrasonic spraying process, the droplets hit the surface of the stent at high speed, and the impact force generated can make the drug molecules better embedded in the stent material, thereby enhancing the binding force between the drug and the stent. This strong bond can ensure that the drug will not fall off easily after the stent is implanted, ensuring the continuous release and therapeutic effect of the drug.
- Prevent drug stratification and peeling: Traditional spraying methods may cause stratification and peeling of drug coatings, affecting the release and therapeutic effect of drugs. Ultrasonic spraying technology can make the drug and the stent surface form a closer bond, avoiding the occurrence of drug stratification and peeling. This is especially important for long-term implanted drug-eluting stents, because the stent needs to maintain stable drug release performance in the body to maintain blood vessel patency and prevent the occurrence of restenosis.
In summary, the ultrasonic drug-eluting stent sprayer plays a vital role in the production of drug-eluting stents. It can achieve precise spraying of drugs, improve drug binding, be suitable for a variety of drugs and stent materials, and improve production efficiency and quality stability, providing safer and more effective medical devices for the treatment of cardiovascular diseases.
