The Structure and Operation of the Single-Wing Blood Drawing Needle


In the realm of medical devices, the sing wing butterfly needle stands as a crucial tool for venipuncture procedures, renowned for its unique design and practicality. Originating from China, the single wing butterfly needle has garnered widespread adoption globally due to its effectiveness and patient comfort.



The single-wing blood drawing needle comprises several key components that contribute to its functionality. At its core is a hollow needle, typically made from stainless steel, which facilitates the penetration of the skin and the insertion into veins. This needle is attached to flexible tubing, allowing for a seamless connection to blood collection tubes or intravenous (IV) lines. The distinctive feature of the butterfly needle lies in its winged handle, resembling the shape of a butterfly, which provides a stable grip during insertion and removal.

Operating the single-wing blood drawing needle requires precision and familiarity with its design. Medical professionals begin by sanitizing the puncture site and securing the patient's arm in a stable position. With a gentle insertion angle, the needle penetrates the skin, guided by the wings of the device. Once positioned within the vein, blood can be effortlessly drawn or medications administered through the attached tubing. The wings of the butterfly needle ensure that it remains secure during the procedure, minimizing the risk of accidental dislodgement.



The single-wing blood drawing needle exemplifies China's contribution to modern medical practices, combining ergonomic design with practical utility. Its structure, characterized by a needle, flexible tubing, and distinctive wings, facilitates accurate venipuncture while prioritizing patient comfort. As healthcare evolves, innovations such as the single-wing blood drawing needle continues to shape the landscape of medical procedures worldwide, emphasizing safety, efficiency, and improved patient outcomes.
