Abstract

OGGETTO DELLA PRESENTE INVENZIONE INDUSTRIALE, E' UNA SIRINGA DI NUOVA CONCEZIONE, ATTA A TRASPORTARE, DOPO L'USO, L'AGO DALL'ESTERNO ALL'INTERNO DEL CILINDRO TRASPARENTE CAVO E QUINDI, ELIMINARE IL PERICOLO DI DIFFUSIONE DI MALATTIE CONTAGIOSE, SPECIE DELL'AIDS, CAUSATE DA PUNTURE ACCIDENTALI DELL'AGO DOPO L'USO. SOMMARIAMENTE IL FUNZIONAMENTO AVVIENE IN PIU' FASI: NELLA PRIMA E SECONDA FASE, SI ASPIRA IL LIQUIDO DA INIETTARE E SI TOGLIE L'EVENTUALE ARIA ASPIRATA, COSI' COME AVVIENE USANDO LE COMUNI SIRINGHE, SOLO CHE UN PICCOLO ACCESSORIO APPLICATO SULLA CORONA DEL CILINDRO IMPEDISCE ALLO STANTUFFO DI PERCORRERE TUTTA LA CORSA DEL CILINDRO CAVO; NELLA TERZA FASE SI TOGLIE IL CITATO FERMO E SI INIETTA TUTTO IL LIQUIDO SPINGENDO LO STANTUFFO FINO IN FONDO; NELLA QUARTA FASE, LO STANTUFFO AGGANCIA L'ELEMENTO A CUI E' APPLICATO L'AGO E, SOLLECITATO DA UNA MOLLA DI RICHIAMO, LO TRASPORTA ALL'INTERNO DEL CILINDRO CAVO. L'AGGANCIO DEL CORPO AGO AVVIENE PER SVITAMENTO. LA MOLLA ASSEMBLATA IN TENSIONE, SI LIBERA NELL'ULTIMA FRAZIONE DELLA CORSA DELLO STANTUFFO. L'AGO UNA VOLTA TRASPORTATO DENTRO IL CILINDRO CAVO, NON PUO' FUORUSCIRE DAL FORO PER IL SUO MOVIMENTO NON ASSIALE.
