ISO 18193 Figure C.2 Vascular Model | Dual Lumen Cannula Recirculation Testing

ISO 18193 Figure C.2 Vascular Model | Dual Lumen Cannula Recirculation Testing

The ISO 18193 Figure C.2 Vascular Model | Dual Lumen Cannula Recirculation Testing is a professional anatomical simulation device manufactured by KingPo. It is specifically designed to replicate the superior vena cava, right atrium and inferior vena cava for recirculation testing of dual-lumen cannulae used in extracorporeal circulation, in full accordance with ISO 18193 Figure C.2 and Annex C.

Technical Parameters

The vascular model is precision-molded from high-clarity medical-grade material to exactly replicate the internal geometry of the superior vena cava, right atrium and inferior vena cava as defined in ISO 18193 Figure C.2. All critical vessel diameters, curvatures and junction angles are manufactured to tight tolerances to ensure repeatable flow dynamics and accurate recirculation visualization.

The transparent construction allows direct observation of ink or particle paths during testing, while the rigid yet anatomically compliant structure maintains dimensional stability under typical test pressures and flow rates. Mounting points are integrated for secure attachment to standard test circuits without flow distortion.

Testing Principle

The model is integrated into a closed extracorporeal circuit with a dual-lumen cannula. Controlled blood-analogue flow is introduced through the cannula while ink or particles are injected to visualize and quantify recirculation between the drainage and return lumens. The test evaluates the degree of recirculation under simulated physiological conditions as specified in ISO 18193 Annex C.

Common Error Mitigation

To ensure repeatable and accurate results, always verify proper cannula insertion depth and alignment within the model before starting the test. Use a consistent blood analogue viscosity and maintain stable flow rates. Regular flushing and visual inspection of the model interior prevent particle residue that could affect flow visualization or lead to false recirculation readings.

Primary Use Cases & Business Value

The ISO 18193 Figure C.2 Vascular Model is used by medical device manufacturers and certification laboratories to evaluate recirculation performance of dual-lumen cannulae. It provides objective, standardized data essential for product development, quality control and regulatory approval of cannulae used in cardiopulmonary bypass and extracorporeal life support.
