FLEXIBLE TUBE POSITIVE DISPLACEMENT PUMP

摘要

In a peristaltic pump system, the pressure rollers (74) are driven by a gear reduction system and are structured and arranged to revolve through a chamber (11) in contact with a flexible tube. The pressure rollers (74) are incorporated into the gear reduction system and are driven by a follower gear (15), which in turn, is driven by a drive gear (19). The pump system further includes a cassette body (62) having a reaction surface (62A); a flexible tube mounted adjacent the reaction surface (62A); and roller gears (70) carrying the pressure rollers (74); and a cassette cap (64) for connecting the roller gears to the cassette body (62).
