They are an essential part of a vacuum blood collection system and are designed to be attached to a collection holder, allowing several tubes to be filled sequentially without removing the needle from the vein.Multi-sample blood collection needles with a hub improve the efficiency of blood draws by allowing multiple tubes to be filled with minimal patient discomfort and reducing the risk of contamination or injury during the procedure.
