Abstract

Resumen El volumen total del fluido en una jeringa puede no ser igual al volumen total del fluido que se puede expulsar de la jeringa: se puede dejar un volumen muerto en una disposición de la jeringa y en un cono de acoplamiento de la aguja provisto con la jeringa. Con el fin de reducir el volumen muerto, se proporciona una disposición de cono de acoplamiento de aguja y jeringa, los cuales están formados de manera complementaria entre sí. Más específicamente, la forma de un plano final de un pistón comprendido por la jeringa es complementario para una forma de un plano en el que se proporciona una abertura de un orificio de cánula del cono de acoplamiento de la aguja. Las formas se presentan de forma que el volumen dentro de la jeringa una vez ocupado por el fluido, pueda ser ocupado por el pistón después de presionar completamente el pistón, o se puede dejar solo un volumen sustancialmente bajo de fluido entre la abertura de la cánula y la jeringa.
