Description Safety Winged Blood Collection Sets — Kawasumi K-Shield® Advantage Butterfly Needle Kawasumi K-Shield® Advantage Safety Winged Blood Collection Sets are engineered for phlebotomy professionals who require reliable needlestick protection without compromising clinical efficiency. Each set features a one-step integrated safety shield that activates immediately after use, confirmed by an audible and tactile click, fully encapsulating the needle and locking permanently in place. No secondary steps. No extra disposal tools required. Flexible, textured wings provide a stable grip during insertion, supporting controlled venipuncture across a range of patient populations — including pediatric, geriatric, and patients with small or fragile veins. Transparent tubing allows immediate blood flash visualization, and the universal female luer lock connection ensures compatibility with standard vacutainer tube holders and blood collection systems. Each box contains 50 sterile, single-use sets, available in 21G, 23G, and 25G. Designed for Safety and Clinical Compliance Needlestick injuries are among the most common occupational hazards in healthcare, and OSHA’s Bloodborne Pathogens Standard requires facilities to implement engineering controls that actively reduce that risk. The K-Shield® mechanism is designed to meet that standard — the safety shield engages in a single motion, requires no activation force during the draw, and cannot be reversed once locked. This makes it a practical choice for high-volume phlebotomy environments where speed and compliance must coexist. These sets are well-suited for hospital phlebotomy departments, outpatient diagnostic labs, urgent care clinics, physician offices, long-term care facilities, oncology clinics, and mobile blood collection services. Gauge Options and Specifications Gauge Wing Color Tubing Length Needle Length 21G Green 12 in 3/4 in 23G Blue 12 in 3/4 in 25G Orange 12 in 3/4 in The 21G is the standard choice for routine adult venipuncture. The 23G offers a balance of flow rate and patient comfort for patients with average vein access. The 25G is recommended for pediatric patients, elderly patients, or any case where vein fragility or size requires a finer gauge needle. Frequently Asked Questions What is a safety winged blood collection set? A safety winged blood collection set — also called a butterfly needle or winged infusion set — is used for venipuncture to draw blood or deliver IV fluids. The flexible wings allow controlled grip and stabilization during insertion, while the integrated safety shield covers the needle immediately after use to prevent accidental needlestick exposure. How does the K-Shield® safety mechanism work? After the draw is complete, the safety shield activates in a single step, fully covering the needle with an audible and tactile confirmation. The lock is permanent — once engaged it cannot be reversed — eliminating the risk of re-exposure during handling and disposal. Are these butterfly needles OSHA compliant? Yes. The K-Shield® Advantage is designed to meet OSHA Bloodborne Pathogens Standard requirements for engineering controls in clinical settings. The passive one-step activation requires no additional force or tools and is suitable for facilities subject to occupational safety compliance requirements. What gauge butterfly needle is used for routine blood draws? The 21G is the most commonly used gauge for standard adult blood draws, providing an efficient flow rate with minimal patient discomfort. The 23G is preferred for patients with smaller veins, and the 25G is typically reserved for pediatric patients or cases requiring the finest available gauge. How many needles come per box? Each box contains 50 sterile, single-use Kawasumi K-Shield® Advantage sets. Available in 21G, 23G, and 25G with 12-inch tubing and a 3/4-inch needle length. Can these sets be used with standard vacutainer tube holders? Yes. The universal female luer lock connection is compatible with standard vacutainer tube holders, syringes, and blood collection systems used across clinical and laboratory settings.
