Abstract

L'invenzione riguarda una siringa autobloccante nel cui stelo è disposto un estrattore che, quando il pistone della siringa è spinto a fine corsa, aggancia l'ago e lo ritrae ad opera di una molla precaricata all'interno dello stelo in posizione protetta e inaccessibile, rendendo inservibile la siringa già dopo il suo primo impiego.Fig.4
