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

Different instruments and ways of use.

1. Instrument: Anti-reflux indwelling needle, also known as anti-reflux needle, is a kind of indwelling needle with anti-reflux function. 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.

2. Usage: The anti-reflux indwelling needle is suitable for patients undergoing long-term infusion, especially when the infusion container needs to be changed frequently, which can ensure the continuity and safety of infusion. The positive pressure indwelling needle mainly pushes the liquid medicine into the patient's venous system through the positive pressure of the pipeline, and the positive pressure indwelling needle is used for short-term infusion treatment, such as intravenous injection, infusion and blood collection.
