Abstract

UNA JERINGA QUE TIENE CARACTERISTICAS DE AISLAMIENTO DE LA AGUJA INCLUYE UN CILINDRO ALARGADO (21) QUE TIENE UN EXTREMO PROXIMO ABIERTO, UNA CAMARA (23) PARA RETENER UN FLUIDO Y UNA PUNTA (25) QUE SE EXTIENDE DESDE EL EXTREMO DISTAL DEL CILINDRO (21) QUE TIENE UN CONDUCTO (28) A TRAVES DE LA MISMA QUE COMUNICA CON LA CAMARA. UN ALOJAMIENTO DE VALVULA (37) SE EXTIENDE HACIA EL EXTERIOR DESDE LA PARTE DE LA PUNTA (25) DEL CILINDRO (21) Y TIENE UN CONDUCTO A TRAVES DEL MISMO EN COMUNICACION CON EL CONDUCTO (28). SE SUMINISTRA UNA CANULA DE AGUJA (41) QUE TIENE UN EXTREMO PROXIMO (42), UN EXTREMO DISTAL (47) Y UN LUMEN A TRAVES DE LA MISMA. EL EXTREMO PROXIMO DE LA AGUJA ESTA CONECTADO CON EL ALOJAMIENTO DE MANERA QUE EL LUMEN SE ENCUENTRE EN COMUNICACION FLUIDA CON EL CONDUCTO. EL ALOJAMIENTO (37) INCLUYE MEDIOS INTERNOS DE VALVULA PARA PERMITIR QUE EL LIQUIDO BAJO PRESION EN LA CAMARA (23) FLUYA DISTALMENTE A TRAVES DEL CONDUCTO Y DEL LUMEN MIENTRAS QUE SE EVITA QUE EL LIQUIDO NO PRESURIZADOEN LA CAMARA FLUYA A TRAVES DE LA ABERTURA. LA VALVULA INTERNA INCLUYE UNA ESTRUCTURA DE VALVULA DE UN SOLO SENTIDO PARA EVITAR QUE EL LIQUIDO FLUYA A TRAVES DEL CONDUCTO EN UNA DIRECCION PROXIMA HACIA LA CAMARA (23)
