Easy to observe. Easy to wash. The artifical blood is designed for all the vascular model to add the realism of the interventional surgery. Its viscosity is remarkably similar to that of human blood, which duplicates the friction coefficients of endovascular devices, wires, and catheters as they traverse the vascular system. It’s easy for doctors to observe the state of stents and catheter and operate precisely. A water based product to effectively simulate wounds and similar effects for theatre, cinema, TV and video with highly realistic results.
