Anesthesia catheter SonoLong Echo

peripheralbox of 10 units

Product
Ultrasound-guided nerve block procedures have redefined continuous regional anaesthesia workflows, increasing demand for optimal needle and catheter visibility and handling. PAJUNK introduced Cornerstone Technology for needles and offers echogenic catheters. The SonoLong Echo catheters are non-metal-reinforced, designed for improved ultrasound visibility and are radiopaque.

Product Overview
The SonoLong Echo system is an echogenic catheter-through-needle solution combining echogenic needles with echogenic catheters, available in LUER and NRFit® connections. Kits include a clamping adapter, 0.2 µm MiniFilter and FixoLong Mini fixation. Catheters feature a central opening and depth markings for controlled positioning.

SonoLong Echo Catheter Features & Advantages

• Non-metal-reinforced catheter engineered for enhanced ultrasound visibility
• Radiopaque design for X‑ray identification
• Central opening catheter tip for continuous infusion
• Depth markings: graduations on the first 30 cm to support accurate catheter placement
• Kit includes Clamping Adapter (yellow), MiniFilter 0.2 µm and FixoLong Mini for secure fixation
• Steel stylet provided to stabilize catheter during insertion

SonoLong Echo Needle Features & Advantages

• Cornerstone Reflectors: 360° graduations on the first 20 mm to optimise ultrasound visibility of shaft and tip, improving echogenicity at steep angles
• Echogenic facet tip (two inclination angles) for enhanced needle-tip visualisation under ultrasound
• NanoLine® coating: ultra-thin polymer film on inner and outer needle surfaces for improved puncture and glide properties; smooth surface; precise stimulation via non‑insulated tip
• Solid black depth markings on needle to support visualization of insertion depth
• Multiple needle tip styles available (Facet tip, Sprotte Special Tip, Tuohy Tip) to suit clinical technique
