Infusion Needle: Precision Access for Implantable Port Systems
Infusion Needle Clinical Purpose
Engineered for reliable, leak-proof access to implanted vascular ports, our infusion needles enable safe delivery of chemotherapy, parenteral nutrition, and long-term IV therapies. The specialized design minimizes coring risk while ensuring secure anchoring during continuous infusions.
The Key Advantages of the Port Access Needle
Optimal Port Integrity
Non-coring bevelled tip (Huber point design) cleanly penetrates silicone septums without generating fragments.
90° right-angle configuration reduces tubing stress and prevents needle dislodgement during patient movement.
Enhanced Safety & Comfort
Low-profile wings with silicone adhesive pads distribute pressure evenly (IAP ≤20mmHg).
Gradual taper transition from needle to tubing eliminates tissue drag (VAS pain ≤2/10).
Procedural Efficiency
Color-coded hubs enable instant gauge identification.
Integrated flashback chamber confirms venous access.
