Abstract

Un dispositivo de administración de líquido tiene un cilindro de jeringa con cámara de depósito para líquido, un émbolo que se traslada a lo largo de un eje longitudinal para expulsar el líquido, y un empujador dimensionado para ser trasladado dentro del cilindro y acoplado a un mecanismo de accionamiento para ponerse en contacto de forma controlada y mover el émbolo. El empujador se pone en contacto con el émbolo en su centro mecánico para reducir la inclinación en el émbolo. Las caras de contacto del empujador y el émbolo cooperaran como una articulación esférica para minimizar las fuerzas no axiales en la cara del émbolo. El empujador puede tener un saliente de diversas longitudes que se extienden hacia y que son recibidas al menos parcialmente en una cavidad de diversas profundidades en el émbolo. El empujador está conectado de forma rígida con un mecanismo de accionamiento para antirrotación. El empujador puede tener bordes festoneados para la ventilación de aire y aberturas para cooperar con los salientes en el mecanismo de accionamiento para prevenir que toque fondo el émbolo cuando se llena.
