<p>According to this invention a safety syringe is provided accommodating a configurative needle holder (7) connected to, or as an integral part of the cylindrical chamber (1), a cylindrical slidable seal means (8) and sealing means (18) and (21), forming the discharge end (30). This includes a plunger means (2) incorporating a use once only plunger seal means (13), slidable contained in the syringe. The plunger means (2) communicating directly after medicament discharge with the cylindrical slidable seal means (8) thus deactivating the sealing means (18, (21) and a plunger seal means (13) to prevent further use of the plunger seal means (13). The plunger means (2) communicate with the cylindrical slidable seal means (8) to stop against the most forward stop means (24), a portion of protrusion (9), such that the cylindrical slidable seal means (8) is locked at lock means (12), through which a shield, in the form of the cylindrical slidable seal means (8), is permanently provided to cover the protrusive needle portion (6). <IMAGE></p> |
