Core Product Advantages

DeWei Medical's Vascular Simulation Model: A Core Tool for Building Interventional Device Showrooms

I. Simulation Structure:

Our company’s simulated vascular models are made using self-developed materials and manufacturing processes. The anatomical structure and dimensions are based on real CT/MRA data from Chinese individuals. The vascular components are made from highly transparent, elastic silicone, crafted using a proprietary silicone formulation and produced via a 3D printing process. The thinnest vessel in the model achieves an inner diameter of just 1.5 mm. This model accurately replicates the physiological structure and mechanical properties of human blood vessels—capturing not only their elasticity and flexibility but also the hemodynamic environment—with remarkable fidelity to real human anatomy. Using our simulated vascular models in the interventional device exhibition hall provides visitors with a more realistic and immersive display experience. Additionally, we also offer Customized Services Based on the unique features of each device and specific display requirements, we design tailored simulation vascular model solutions to ensure optimal presentation results.
