Abstract

Il presente trovato si riferisce ad una cartuccia igroscopica particolarmente per filtri per impieghi in ambito medico-chirurgico che comprende un elemento a nastro avvolto per formare una bobina piana.La peculiarità del trovato è costituita dal fatto che il citato elemento a nastro è costituito da un primo nastro, presentante corrugazioni che si sviluppano lungo direzioni trasversali rispetto allo sviluppo longitudinale del citato elemento a nastro e realizzato in materiale plasticamente deformabile e conduttore del calore, e da un secondo strato impregnato con sali igroscopici.Le citate corrugazioni definiscono canalicoli per il passaggio di un flusso di aeriforme trasversalmente al piano di giacitura della citata bobina piana.
