ABSTRACT:
The device for protecting against accidental butterfly needle punctures has a hollow body which delimits an internal accommodation seat for a butterfly needle which is connected to a flexible duct for feeding or withdrawing fluid. The seat has a proximal terminal portion, provided with two longitudinal lateral slits in each of which a respective wing of a butterfly needle can slidingly engage. The seat also has a distal terminal portion provided with retention members for engaging a butterfly needle. A butterfly needle can slide along the seat from a removal start position in the proximal terminal portion toward an irreversible complete retraction position within the distal terminal portion.
