Schlauchkassette einer peristaltischen Pumpe für Blutbehandlungssysteme und dergleichen

摘要

The cassette has two peristaltic pump loops (134,136), projecting from sidewalls outside the cassette and connecting with ports (T4-T7). The cassette is formed internally with a series of first cavities (FN), which define a primary path (F1), leading from a liquid port (T1) on the sidewalls, and branch paths (F4-F7 and F11-F19) between the primary path and the pump loop ports. Second cavities define valves (VN) with diaphragms (116) and which can be actuated to switch flow from the primary path (F1) between the branch paths.
