Contemporary Nursing

Venous catheterization is a key vascular access technique in clinical critical care and long-term treatment. The traditional management model has drawbacks such as static and fixed information, lagging updates, and scattered maintenance records. The existing static QR code solution also cannot meet the dynamic needs of nursing work. This study innovatively constructed a “one catheter, one code” dynamic information management scheme. Using digital tools and a hierarchical authorization mechanism, it realizes the organic unity of real-time update in the background and convenient query at the front end. It integrates the core static information of the catheter, dynamic maintenance records, and status markings, upgrading the paper labels to a real-time updateable “digital loose-leaf binder”, forming a visualized catheter life log. This scheme significantly improves information timeliness and management continuity, providing precise support for clinical decision-making, nursing handover, risk traceability, and team collaboration. It is a lightweight innovative practice in the process of nursing informatization and has significant promotion value.
