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).According to the invention, it realizes a disposable syringe for pharmaceutical use which has in combination: - a cylindrical jacket (8) external to the cylinder (2) of the syringe equipped with a flange (10) adapted to support the fingers of the hand that engage the syringe ; - a spring (15) interposed between the liner and the cylinder (2) of said syringe; - at least a pair of elastic hooks (11) belonging to the cylindrical liner which hold the syringe when the piston (3) of the same is not at end of stroke. When an intermediate flange (20) belonging to the piston rod pushes the piston fully so that all the liquid contained in the syringe is expelled, the intermediate flange interacts with the elastic hooks (11) and releases the syringe from the jacket and moves it the syringe with the needle backwards, so that the needle is protected by the jacket (8).
