PCT No. PCT/FR94/00976 Sec. 371 Date Mar. 28, 1996 Sec. 102(e) Date Mar. 28, 1996 PCT Filed Aug. 3, 1994 PCT Pub. No. WO95/04886 PCT Pub. Date Feb. 16, 1995A peristaltic pump cassette (1) is designed to cooperate in use with a motor unit (2) through a drive spindle (30) comprising a casing (40) with a tube bearing surface (12), a deformable tube (11), rotating rollers (14) driven by friction by the drive spindle (30). The deformable tube (11) is applied onto the support surface (12) and is deformed by rotating rollers (14), in order to produce driving of a liquid contained therein. Before first use, the radial position of rollers (14) is such that the tube (11) is not closed. During first use, they are moved radially by inserting the drive spindle (30), thus closing the tube (11). After use, rollers (14) remain in the radial position that keeps the tube (11) closed.
