Abstract (en)
[origin: WO2022136462A1] A peristaltic pump (10) comprises a drivable rotor (14), having at least one pressing member (15), and a housing (11) comprising a cylindrical stator (12) in which the rotor (14) is rotatable. Flexible tubing (22), having an inlet side (24) and an outlet side (26), extends circumferentially around the cylindrical stator (12) against an inner wall (12a). The peristaltic pump (10) includes a radially deformable ring (28) positioned between the (rotor (14) and the circumferentially extending flexible tubing (22). The ring (28) is deformed by the pressing member (15) upon rotation of the rotor (14) and this compresses the flexible tubing (22) against the inner wall (12a) of the cylindrical stator (12) to convey liquid along the flexible tubing (22). The radially deformable ring (28) includes a ring anchor (30) which prevents rotation of the radially deformable ring (28) during rotation of the rotor (14). The ring anchor 30 is engaged with the housing (11) to secure the ring anchor (30) to the housing (11) whilst allowing reciprocal movement of the ring anchor (30) in a radial direction.
