Blood Collection Sets

About

Blood collection sets are medical devices designed for drawing blood from a patient’s vein for laboratory testing, blood transfusion, or donation. In clinical settings, they are often called "butterfly needles," "winged infusion sets," or simply "blood draw sets." Uses of Blood Collection Sets Venipuncture (Drawing Blood): The main purpose of blood collection sets is to draw blood from a vein, typically for lab testing or blood donation. They are commonly used when routine blood draws are performed—either at hospitals, clinics, or diagnostic laboratories. Difficult Veins: The design of these sets is particularly useful for patients with small , fragile , or hard-to-reach veins (such as children, elderly patients, or those receiving chemotherapy). The smaller gauge and flexible tubing allow for more precise control and less discomfort. Multiple Tube Collection: Blood collection sets are often used with vacutainer systems or blood culture bottles , allowing healthcare workers to fill several tubes from a single venipuncture. Features of a Blood Collection Set Winged Needle: Soft, flexible “wings” help in gripping and precisely positioning the needle. Short Needle, Usually 21G-23G: Fine enough for delicate veins. Flexible Tubing: Allows easier positioning and movement of the patient’s arm during blood draw. Connector: The tubing often ends in a connector compatible with vacuum collection tubes or syringes. Safety Mechanisms: Many modern sets have safety features to protect healthcare staff from accidental needle sticks after use. Types of Procedures Routine and specialized blood tests (CBC, chemistry panels, cultures) Blood donation Therapeutic phlebotomy Blood collection sets are specialized medical devices for safely and efficiently collecting blood from a vein—often used for people with difficult veins and for procedures needing multiple blood samples with minimal discomfort to the patient.
