The multi-side hole drug discharge design at the tip ensures even drug dispersion and a better anesthesia plane. The front 10cm and middle window design makes it easy to observe the backflow situation.
The ballpoint pen-style tip is better than the traditional straight-hole steel wire catheter, which can avoid the risk of wire exposure. The rounded tip can flexibly turn when encountering obstacles, reducing damage to blood vessels, nerves, etc.
The head end adopts an elastic design and will "actively" avoid obstacles when encountering them, which can reduce the risk of ordinary catheters puncturing blood vessels, nerves, and dura mater due to the excessively hard tube head.
 The built-in spiral spring steel wire in the tube supports the tube body to keep the liquid fluid flowing and is not easy to bend, knot or break.
