Abstract: Infusion kit includes: a butterfly needle having a stiff rod-shaped body, at least a pair of coplanar wings laterally and outwardly extending therefrom; a cavity for receiving a slide, supporting a sliding needle from which an element projects and engages a straight groove along the body; the element being longer than the cavity and projecting from the body, is insertable in a housing connected to the groove to compressibly block a spring between the slide and the cavity bottom wall; an infusion cannula including a central and hollow cylinder, a flexible element, at least a coupling having an inner passage; the flexible element and the passage communicating via the cavity to allow draining a fluid or the supply from the outside; the flexible element is hollow and allows insertion of the needle of the butterfly needle through the cavity; at least a pair of coplanar wings extend from the cylinder.

Abstract: The invention refers to the field of self-locking safety disposable syringes with needle protection after use. The syringe comprises a hollow barrel (1) ending on its lower side with an internal seat (2) adapted to receive a hub (3) carrying a cannula (4). A hollow driving rod (5) adapted to house a spring (6) is inserted in the hollow barrel. Such rod is closed at its lower end by an extracting element (8) that can slide into the hollow driving rod. The extracting element has an annular notch (9) in which a sealing ring rubber gasket (10) is housed that seals the internal wall of the hollow barrel (1). The extracting element (8) with related sealing ring gasket (10) form a liquid sucking and compressing plunger.
