Abstract

A disposable cartridge (20) for a peristaltic micro pump is disclosed. The cartridge comprises a housing (21) with an inlet connector (25) and an outlet connector (26). A fluid channel (23) extends in the housing (21) between the inlet and the outlet with a channel section (22) of the fluid channel (23) provided by a flexible tube (24). One or more openings are provided adjacent to the channel section (22) in the housing (21) allowing one or more pump engaging elements of a pump drive to engage the flexible tube (24), compressing the flexible tube (24) to pump fluid through the fluid channel (23). Sealing elements (31, 32) with double flange extensions (31a, 31b) having a first inner flange (31a, 32a) and a second outer flange (31b, 32b) are provided to seal at the connectors (25, 26) and fix the tube (24) in the housing (21).
