Life medical Nano-coating is very thin comparing to the traditional insulation methods. The Nano-coating insulation won't change the ID and OD as well as the surface of the needle which results in less puncture resistance and accurate positioning. 
Dual nerve positioning with ultrasound guidance and nerve stimulation, more precise nerve block effect, no dead ends in positioning. Design benefits:
Visualize Insertion Depth:
①1cm depth markings provide visual confirmation ofinsertion depth.
②Golden Nano-coating provides easy visualization without changing electrical properties of the needle.
Ultrasound visualization and tip identification
360° visibility--360°marking designed for ultrasound visibility from all sides                                                                  ldeal inner cavity nano-coating for better liquid flow
The tip of the needle conducts electricity, and a variety of needle tips protect the nerves
