Uncontrolled backflow during multi-phase injection leads to cross-contamination and inaccurate dosing. Preventing this ensures patient safety and maintains the integrity of the fluid delivery sequence.

Exposure of critical injector interfaces and syringe components to environmental pathogens or debris leads to patient infection. Preventing ingress at connection points ensures sterile integrity during high-pressure medical procedures.

Unintended reverse flow in injector systems risks cross-contamination and pressure-induced mechanical failure. Preventing backflow ensures sterile integrity and protects sensitive delivery hardware.
