Abstract

Filtro para líquido apropiado para ser utilizado en un circuito extracorpóreo de circulación de sangre, que incluye: una envoltura tubular hueca que tiene una pared lateral, una pared superior que presenta un punto más alto en su centro, y una pared de fondo, una salida de gas en dicha pared superior en dicho punto más alto, un núcleo tubular perforado dispuesto concéntricamente en el interior de dicha envoltura, un elemento de filtro cilíndrico que rodea dicho núcleo y que esta desplazado con relación a dicha pared lateral, una cubierta de elemento de filtro que cubre las extremidades superiores de dicho núcleo y de dicho elemento de filtro y que está desplazada con relación a dicha pared superior, una entrada de líquido sustancialmente horizontal formada en dicha pared lateral en un punto adyacente de dicha pared superior, y una salida de filtrado formada en dicha pared inferior de dicha envoltura y en comunicación con el espacio interior de dicho núcleo, siendo la superficie superior dedicha cubierta del elemento de filtro simétrica alrededor del eje longitudinal de dicha envoltura, teniendo un punto más elevado en su centro, y estando desprovista de cualquier punto de altura mínima localizada, y estando adaptada dicha entrada para dirigir la circulación entrante del líquido de manera no perpendicular contra la pared lateral de dicha envoltura, con lo cual se establece una circulación turbulenta de líquido al exterior de dicho elemento de filtro y encima de dicha cubierta del elemento de filtro.
