The unique α-type single pigtail design, with precision-machined burr-free side holes on the curled loop, effectively prevents catheter migration and dislodgement, while ensuring unobstructed drainage of urine, exudate, ascites and other bodily fluids. All our single pigtail drainage tubes are strictly produced in a Class 100,000 cleanroom, fully compliant with international medical device standards, and widely trusted by hospitals, clinics, and medical distributors across global markets.
TPU Pigtail Drainage Tube
TPU Pigtail Drainage Catheter Exceptional Biocompatibility: Our high-purity medical TPU material is non-toxic, non-irritating, with minimal tissue reaction, significantly reducing the risk of mucosal inflammation, encrustation and adhesion during short-to-medium term indwelling, supporting up to 3 months of safe clinical use.
Outstanding Kink & Corrosion Resistance: The high elasticity, tensile strength and memory performance of TPU ensure the catheter maintains a smooth, unobstructed lumen even under extreme bending, eliminating lumen occlusion and drainage failure. It is highly resistant to corrosion from bodily fluids and urine, maintaining stable performance throughout the indwelling period.
Full Radiopacity: The catheter is formulated with uniform medical-grade radiopaque additives, enabling full-length clear visibility under X-ray and fluoroscopy, allowing clinicians to accurately position, adjust and monitor the catheter during and after placement.
Body-Temperature Adaptive Softness: The TPU material automatically softens at human body temperature, conforming to the natural anatomical structure of the human body, greatly reducing patient discomfort and tissue trauma during intubation and long-term indwelling.
Reliable Anti-Migration Fixation: The α-type single pigtail curled end forms a stable, self-retaining fixation loop, which effectively locks the catheter at the target drainage site, significantly reducing the risk of catheter slippage, migration and accidental dislodgement compared to traditional straight drainage catheters.
Precision Multi-Side Hole Layout: The pigtail loop is equipped with evenly distributed, burr-free side holes, which maximize the effective drainage area, prevent blockage from tissue debris and blood clots, and ensure continuous, unobstructed fluid drainage.
Atraumatic Smooth Tip: The distal tip of the catheter is precision polished to a smooth, rounded atraumatic end, minimizing mucosal damage and bleeding during percutaneous insertion, improving procedural safety and patient comfort.
High-Contrast Depth Markings: The catheter body is printed with wear-resistant, high-contrast black depth markings (as shown in the product image), enabling clinicians to accurately control the insertion depth and ensure precise placement at the target site.
Each catheter undergoes 100% rigorous dimensional inspection, air tightness testing and surface smoothness inspection before leaving the factory to ensure zero product defects.
Sterilized by ethylene oxide (EO), the product is fully aseptic and ready for immediate clinical use, eliminating the need for pre-operative sterilization and reducing the risk of cross-infection.
Single-use design strictly prohibits secondary reuse, ensuring maximum clinical safety for both patients and medical staff.
