Infusionsfilter

Abstract

The present disclosure relates to an infusion filter (14; 114; 514; 1014; 1114; 1214) which is designed to filter out particles and / or bacteria and / or endotoxins and / or fungi from an infusion fluid and to separate air contained in the infusion fluid, comprising a housing (24) extending from an inlet area (20) to an outlet area (22) along a longitudinal axis (21), wherein a filter membrane (26; 126; 226; 326; 426; 526; 626; 726; 826; 926; 1026; 1126; 1226; 1326; 1426; 1526; 1626;1726) is arranged, which is designed to filter out particles and / or bacteria and / or endotoxins and / or fungi from the infusion fluid, wherein an inlet-side venting membrane ring (34a) is arranged in the inlet area (20), and wherein an outlet-side venting membrane ring (36a) is arranged in the outlet area (22), wherein both venting membrane rings (34a, 36a) are hydrophobic and connect an interior space of the housing (24) with the environment, thereby enabling them to separate (independent of position) air contained in the infusion fluid during priming and during therapy, wherein both venting membrane rings (34a, 36a) are disc-shaped, in particular annular, and surround the longitudinal axis (21). Furthermore, the disclosure relates to an infusion set (6) with an infusion filter (14; 114; 514; 1014; 1114;1214) and a tube (12, 16), an infusion device (2) with an infusion set (6), an infusion container (4) and an infusion access (8). Finally, a method for manufacturing such infusion filters (14; 114; 514) is disclosed.
