Abstract

UNA JERINGUILLA PARA MEDICAMENTOS ENCAPSULADOS QUE TIENE UNA AGUJA DE RETRACCION AUTOMATICA, UNA VEZ QUE EL CONTENIDO DE LA CAPSULA HA SIDO LIBERADO. LA CAPSULA (50,125) ES SITUADA AL MENOS PARCIALMENTE DENTRO DE UN PISTON ACTIVADOR HUECO (34,145,245) Y ES LIBERADO PARA UNA POSTERIOR RETRACCION (22,121) EN EL MISMO MEDIANTE UN EMBOLO (40,132,232). EL EMBOLO (40,132,232) SIRVE PARA OPERAR EL PISTON (52,130) CONTENIDO EN LA CAPSULA Y TIENE UNOS BRAZOS DE CIERRE RETRAIBLES (42,137,237), QUE SE EXTIENDEN LATERALMENTE HASTA UNA RELACION DE ENGANCHE CON UNA FORMACION DE SUJECCION (38,147,247) DEL PISTON ACTIVADOR. LA LIBERACION DE LOS BRAZOS MEDIANTE EL CONTACTO CON EL EXTREMO TRASERO ABIERTO DE LA CAPSULA (50,125) PERMITE LA RETRACCION DE LA AGUJA Y LA CAPSULA. TAMBIEN SE EXPONE LA INSERCCION DE LA AGUJA Y LIBERACION DE LOS CONTENIDOS DE LA CAPSULA AUTOMATICAMENTE.
