SAFETY DEVICE FOR A SYRINGE

Abstract

The invention concerns a safety device (100) for a syringe comprising a connector (3) which can be coupled to a syringe (10), a main body (4) provided with a cavity (44) and which can be coupled to the connector (3) so as to extend above it and a needle body (5) for supporting and housing a needle or cannula (7), the needle body (5) longitudinally extending in the connector (3) and in the main body (4). The device (100) further comprises a push element (9), which can be coupled to a distal end of the needle body (5) and movable inside the connector (3) by action of an axial thrust of a plunger of the syringe, and a needle support (8) which can be coupled to the needle body (5) and is operable by the push element (9) between a locked position of the needle body (5), wherein the needle support (8) is interposed between the connector (3) and the needle body (5), and an unlocked position of the needle body (5), wherein the needle support (8) is released from the connector (3) and from the needle body (5) and completely housed in the cavity (44) of the main body (4) and the needle or cannula (7) can freely retract through the main body (4) and the connector (3). The invention also concerns a syringe (10) provided with such a safety device (100).
