Difference between anti-reflux indwelling needle and positive pressure indwelling needle

A valve or diaphragm is added between the needle and the infusion tube, which can keep the smooth delivery of liquid by preventing the occurrence of reflux phenomenon, while the positive pressure indwelling needle is suitable for patients who need to deliver drugs or liquids but do not have the function of preventing reflux.
