Abstract: Safety device for taking samples and performing infusions which comprises: a grip end provided with a coupling for connection to a fluid supply duct; a delivery end for a container for collecting fluid; a double-tip needle in which the tip proximal with respect to the supply duct is directed toward the grip end and the distal end is directed toward the delivery end; a needle support engaging an intermediate portion of the needle and movable from an inactive position to an active position toward the grip end in order to cause the proximal tip of the needle to penetrate the supply duct; elastic return means for said support; and an element for abutment at the delivery end for acting as a locator for a collection container, which moves with respect to the needle between a retracted needle protection position and a protruding position for insertion on the needle in order to expose its distal tip and simultaneously insert it in the collection container.

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.
