Ống thông tĩnh mạch và động mạch Nexus
Đa năng tĩnh mạch Và động mạch ống thông hỗ trợ tuần hoàn ngoài cơ thể trong quá trình tuần hoàn ngoài cơ thể hoặc ECMO, đảm bảo tối ưu lưu lượng dòng chảy Và khả năng tương hợp máu.
Cardiopulmonary Bypass (CPB) Cannulas are specifically designed to facilitate veno-venous Và veno-arterial access during extracorporeal circulation (e.g., cardiopulmonary bypass, ECMO, hoặc short-term mechanical circulatory support). Engineered for peripheral vessel cannulation, these cannulas offer a chắc chắn, đáng tin cậy, Và ít xâm lấn interface between the patient’s vascular system and the extracorporeal circuit, ensuring stable blood flow for a wide array of cardiac and respiratory can thiệp.
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.
Wide Lumen Variants
- Enhanced Flow Capacity: Allows efficient blood drainage and return for veno-venous hoặc veno-arterial support.
- Optimized Pressure Dynamics: Maintains adequate flow rates with minimal resistance, essential for stable hemodynamic management.
Bio-Compatible Materials
- Medical-Grade Polymer: Ensures low thrombogenic potential, durability, and resistance to tear or puncture.
- Integrated Reinforcement (optional, depending on model): Offers added torque control Và kink resistance during cannula positioning.
Secure Connection Hub
- 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.
