100Khz Ultrasonic Probe Nozzle for Blood Vessel Extraction with Deep Cavity Direct Spraying

The 100Khz ultrasonic probe nozzle for blood vessel extraction represents the cutting edge of medical coating technology, featuring high precision, deep cavity capabilities, and functional development. This innovative design combines high-frequency ultrasonic spraying technology with customized probing nozzles, specifically engineered for inner wall coating requirements of suction vessels, particularly slender lumens.

• Deep Cavity Direct Spraying: Traditional external spraying struggles with even coverage in slender lumens, while the probing nozzle extends directly into the lumen for internal-to-external or sectional spraying
• 360° Radial Atomization: Nozzle front end features circular or porous radial structure, enabling atomization perpendicular to the pipe wall for uniform circumferential coverage
• Adaptable Dimensions: Adjustable nozzle diameter (1-5mm) and customizable length (5-30cm) to match various products from short blood collection vessels to central venous long catheters

• Anticoagulant Coating Treatment: Uniform heparin molecule layer formation on blood vessel inner walls, effectively inhibiting blood contact activation and reducing thrombosis risk. Superior coating uniformity and stability compared to traditional soaking methods with higher heparin activity retention.
• Antibacterial/Anti-infective Coating: Spray coatings containing silver nanoparticles, chlorhexidine, minocycline and other antibacterial agents to prevent catheter-related bloodstream infections (CRBSI). Ensures uniform nanoparticle dispersion without agglomeration.
• Endoendothelialization Promoting Coating: Bioactive molecules such as vascular endothelial growth factor (VEGF), fibronectin, and collagen promote vascular endothelial cell adhesion and growth on tube walls, reducing damage from long-term retention.
• Anti-proliferative Drug Coating: Application of paclitaxel, sirolimus and similar drugs on hemodialysis catheters to inhibit smooth muscle cell proliferation and reduce luminal stenosis risk.
• Multi-functional Composite Coating: Through multi-layer or mixed spraying technology, enables multifunctional integration such as "anticoagulation+antibacterial" and "anti-proliferation+endothelialization" to meet complex clinical requirements.
