Abstract

MECANISMO DE JERINGUILLA HIPODERMICA (20) QUE INCLUYE UN CUERPO CILINDRICO (21) CON UN EXTREMO ABIERTO PROXIMO (22) UNA CAMARA (23) PARA RETENER EL FLUIDO Y UNA PORCION DE LA PUNTA (25) QUE SE EXTIENDE DESDE UN EXTREMO DISTANTE (27) DEL CUERPO CILINDRICO (21) CON UN PASAJE (28) QUE SE COMUNICA CON LA CAMARA (23). LA CANULA DE LA AGUJA (29) CON UN EXTREMO DISTANTE (31) SE EXTIENDE HACIA FUERA DESDE LA PORCION DE LA PUNTA (25) E INCLUYE UN LUMEN (33) EN COMUNICACION FLUIDA CON EL PASAJE (28). UN MECANISMO DE MONTAJE DE CAPA DE PROTECCION (40) INCLUYE UNA FUNDA DE AGUJA FLEXIBLE (41) CON UN EXTREMO ABIERTO PROXIMO (43), UN EXTREMO DISTANTE CERRAD (44), UNA PARED LATERAL (45) QUE DEFINE UN RECEPTACULO (46) EN EL MISMO Y SE COLOCA DENTRO DE UN CAPA PROTECTORA RIGIDA ALARGADA (51) CON UN EXTREMO ABIERTO PROXIMO (52), UN EXTREMO DISTANTE (53) Y UNA PARED LATERAL (55) ENTRE ELLOS. SE PROPORCIONA UNA ESTRUCTURA PARA MANTENER LA FUNDA (41) DENTRO DE LA CAPA PROTECTORA (51) DE MODO QUE LA FUNDA (41) MO SE PUEDA RETIRAR DE LA CAPA PROTECTORA (51) DURANTE LA UTILIZACION NORMAL DE LA JERINGUILLA (20). LA FUNDA (41) INCLUYE UN MEDIO DE CIERRE DE LA CANULA EN EL EXTREMO DISTANTE DEL RECEPTACULO (46). EL MECANISMO DE LA CAPA PROTECTORA DE LA AGUJA (40) ESTA COLOCADO CON EL EXTREMO DISTANTE (31) DE LA CANULA ACCIONANDO EL METODO DE SELLADO DE LA CANULA, Y EL EXTREMO PROXIMO (43) DE LA CAPA PROTECTORA (41) QUE SE PUEDE QUITAR ENGRANANDO LA PORCION DE LA PUNTA (25) PARA MANTENER EL MECANISMO DE LA CAPA DE PROTECCION DE LA AGUJA (40) SOBRE EL CUERPO CILINDRICO (21) MIENTRAS QUE CIERRA SIMULTANEAMENTE EL LUMEN (33) DE LA CANULA (29) DE FORMA QUE LA FUNDA (41) RODEE LA PORCION COMPLETA DE LA CANULA (29) QUE SE EXTIENDE HACIA FUERA DESDE LA PORCION DE LA PUNTA (25) DEL CUERPO CILINDRICO (21).
