Catheter Features：

　　The catheter is made of imported medical-grade polyurethane：

　　●offering excellent flexibility,kink resistance,and superior biocompatibility to ensure patient comfort during prolonged use.

　　●Hydrophilic Coating:Reduces friction for smoother insertion,minimizes tissue adhesion,and facilitates easier catheter removal.

　　●Radiopaque Markers:Provide enhanced visibility under X-ray for easy identification and accurate positioning.

　　●Oval Side Holes:Ensure unobstructed drainage and effectively reduce the risk of catheter clogging.

　　Patented Technology（Dual-Lumen Visualized Negative Pressure Hollow Core with Negative Pressure Balloon）：

　　●During puncture,the one-way aspiration ball maintains negative pressure,utilizing suction to draw fluid into the observation window,facilitating precise catheter positioning through a one-step insertion technique.

　　●Made from medical-grade materials,it enables accurate localization of the needle tip under imaging to reach the puncture site.This achieves precise puncture positioning and visualization,thereby avoiding the disadvantages of blind puncture,such as prolonged procedure time,low success rate,and serious complications like damage to tissues and nerves.
