PCT No. PCT/EP93/01899 Sec. 371 Date Mar. 23, 1995 Sec. 102(e) Date Mar. 23, 1995 PCT Filed Jul. 19, 1993 PCT Pub. No. WO94/02192 PCT Pub. Date Feb. 3, 1994The hygroscopic cartridge (1) particularly for filters for medical use, has a band-like element (2) which is wound to form a flat bobbin (7). The band-like element (2) has a first band (3), formed with corrugations (4) which extend in a transverse direction with respect to the longitudinal extension of the band-like element (2) and made of a heat-conducting plastically deformable material, and a second layer (5) impregnated with hygroscopic salts. The corrugations (4) define small channels (8) for allowing the passage of an aeriform flow in a transverse direction with respect to the plane of lay of the flat bobbin (7).
