Nexus เข็มเจาะหลอดเลือดดำและหลอดเลือดแดง

อเนกประสงค์ หลอดเลือดดำ และ เส้นเลือดแดง เข็มสอดช่วยพยุง การไหลเวียนนอกร่างกาย ในระหว่างการบายพาสหัวใจและปอดหรือ ECMO เพื่อให้มั่นใจว่าเหมาะสมที่สุด อัตราการไหล และ ความเข้ากันได้ของเลือด.

Cardiopulmonary Bypass (CPB) Cannulas are specifically designed to facilitate veno-venous และ veno-arterial access during extracorporeal circulation (e.g., cardiopulmonary bypass, ECMO, หรือ short-term mechanical circulatory support). Engineered for peripheral vessel cannulation, these cannulas offer a ปลอดภัย, เชื่อถือได้, และ การบุกรุกน้อยที่สุด interface between the patient’s vascular system and the extracorporeal circuit, ensuring stable blood flow for a wide array of cardiac and respiratory การแทรกแซง

Anatomically Informed Profiles
  • Smooth Tapered Tips: Reduce vascular trauma and simplify vessel insertion.
  • Ergonomic Shaft Curvature: Aligns with standard venous or arterial anatomy (e.g., femoral, jugular, subclavian), minimizing the risk of kinking or malposition.
  • Enhanced Flow Capacity: Allows efficient blood drainage and return for veno-venous หรือ veno-arterial support.
  • Optimized Pressure Dynamics: Maintains adequate flow rates with minimal resistance, essential for stable hemodynamic management.
  • Medical-Grade Polymer: Ensures low thrombogenic potential, durability, and resistance to tear or puncture.
  • Integrated Reinforcement (optional, depending on model): Offers added torque control และ kink resistance during cannula positioning.
  • ISO-Standard Connectors: Provide a leak-proof interface to the extracorporeal circuit’s tubing and pumps.
  • Smooth Transition: Minimizes shear forces on blood cells, lowering hemolysis risk.
