Traditional infusion devices consist of six core components: the infusion tubing, which comes into direct contact with the medication, forms the infusion pathway; the needle enables vascular puncture; the dropper is used to monitor the infusion process; the particulate filter intercepts foreign objects larger than 5 μm in diameter; the regulating clamp adjusts the flow rate by mechanically changing the tubing diameter; and the air inlet maintains pressure balance within the bottle.
