Abstract

Secondo l'invenzione di realizza una siringa monouso per uso farmaceutico che presenta in combinazione:- una camicia cilindrica (8) esterna al cilindro (2) della siringa dotata di una flangia (10) atta ad appoggiare le dita della mano che impegnano la siringa;- una molla (15) interposta tra la camicia e il cilindro (2) di detta siringa;- almeno una coppia di ganci elastici (11) appartenenti alla camicia cilindrica che trattengono la siringa quando il pistone (3) della stessa non è a fine corsa. Quando una flangia intermedia (20) appartenente all'asta del pistone spinge a fondo il pistone affinché tutto il liquido contenuto nella siringa venga espulso, la flangia intermedia interagisce con i ganci elastici (11) e opera lo sganciamento della siringa dalla camicia e lo spostamento della siringa con l'ago all'indietro, così che l'ago viene protetto dalla camicia (8).
