What is the function of the Winged Infusion System in medical practice?

The Winged Infusion System, commonly known as a butterfly needle, is primarily designed for the collection of blood samples. This device features flexible wings on either side of the needle, which provide better stability and control during the venipuncture process. When using a butterfly needle, the clinician can access smaller veins or perform venipuncture in patients with challenging vascular access, such as in pediatric or elderly patients. The design allows for precise placement and minimizes discomfort for the patient.

While the Winged Infusion System can be used for administering medications, especially in smaller doses, its primary function is to facilitate blood collection processes. Other devices, such as larger bore needles or IV catheters, are typically used for intravenous drug administration. Similarly, for measuring heart rate or performing EKG tests, different instruments and equipment are required, which are not within the capabilities of a butterfly needle.
