Abstract
The invention relates to a fluidic duct structure for the cassette of a peristaltic pump, that comprises: a duct-forming assembly (22) made in a rigid plate (16); two connection means (28, 30) connected to said duct-forming assembly; a deformable piping (36) extending outside said plate and having two ends (36b, 36c) respectively connected to said connection means, said piping including a portion substantially in the shape of a semi-circle for cooperation with the rotor (82) of the peristaltic pump; and connection means (86, 90, 92) of said duct-forming assembly for connecting said ducts to fluidic components to be mounted on the cassette. The duct-forming assembly comprises a hollow pattern (40) giving into a surface of the plate (16) and a thin film (26) tightly attached on the surface of the plate opposite the hollow pattern.
