Abstract

Un dispositif d'échange thermique avec le sang (10) comporte généralement une pluralité de petits conduits creux (32) en matière polymère destinés au transport du sang. Ces conduits creux (32) sont fabriqués à partir d'une forme plate enroulée en couches autour d'un axe (16). Les couches des conduits creux (32) sont espacées les unes des autres par un écarteur à mailles (40). Cet écarteur à mailles (40) a des trous (44) à travers lesquels un fluide caloporteur tel que l'eau peut circuler de façon plus efficace au-dessus et autour de la surface externe desdits conduits creux (32). Ledit fluide caloporteur effectue un échange thermique avec les surfaces externes des conduits creux (32) qui à leur tour effectuent un échange thermique avec le sang traversant lesdits conduits creux (32). Cette invention concerne également un échangeur thermique (10) qui s'avère plus efficace que les échangeurs thermiques connus de l'état antérieur de la technique du fait que l'écoulement du fluide caloporteur au-dessus et autour de la surface externe des conduits creux (32) est plus efficace.
