Flow rate-setting and adjustable infusion sets for single-use are specialized, disposable intravenous devices featuring an integrated, high-precision dial regulator to accurately control medication or fluid delivery (typically 5–300 ml/hr) without an electronic pump. These sets improve safety by preventing free-flow, minimizing contamination risks, and allowing precise titration for clinical applications. 

These devices are vital in settings requiring accurate, controlled medication delivery without the expense or bulk of, traditional, electrical, infusion, pumps, such as, in, emergency, or, limited-resource, environments.
