Final answer:
The winged infusion set includes a retractable needle system, textured wings for better grip and control, a transparent section for monitoring blood flow, and color-coding for gauge identification, all designed to improve safety during venipuncture.
Step-by-step explanation:
The winged infusion set, commonly referred to as a butterfly needle, has several safety features designed to reduce the risk of needlestick injuries and ensure safe venipuncture procedures. One key safety feature is the retractable needle system, which allows the needle to retract into the plastic casing immediately after use, thus preventing accidental needlestick injuries to both the healthcare provider and patient. Additionally, these sets often come with a flexible, textured 'wing' that can be held securely, allowing for greater control during insertion and to ensure proper positioning of the needle. To further enhance safety, many winged infusion sets also include a transparent tubing section for visual confirmation of successful venous access and to monitor blood flow. Some newer models also have color-coded systems to help identify the needle gauge quickly.
