Abstract

SE FACILITA UNA JERINGA QUE INCLUYE UN BARRILETE, UN EMBOLO Y UN VASTAGO DE EMBOLO. EL EMBOLO PUEDE DEFORMARSE A TRAVES DEL VASTAGO DEL EMBOLO PARA ARRASTRAR LAS PAREDES DEL EMBOLO DESDE LA PARED INTERIOR DEL BARRILETE Y REDUCIR LA FRICCION ENTRE EL EMBOLO Y EL BARRILETE, FACILITANDO LA INYECCION. IGUALMENTE SE PUEDE UTILIZAR ESTA CAPACIDAD DE DEFORMACION PARA MEJORAR LA ASPIRACION DE LA JERINGA. ESTA INVENCION TAMBIEN PROPORCIONA UN METODO PARA INTRODUCIR UN MEDIO LIQUIDO EN UN PACIENTE UTILIZANDO DICHA JERINGA.
