Butterfly epicranial needles without safety guards are indicated for blood sampling, intravenous infusions, and all procedures requiring rapid and controlled venous access. Thanks to their flexible wings, they are also suitable for small-caliber veins or patients with difficult access, facilitating precise and stable insertion. They are used in hospitals, clinics, analysis laboratories, emergency rooms, and home care settings, where efficient management of collection and administration procedures is required. Their versatility makes them an essential tool in clinical routines and in intravenous diagnostic and therapy services.
