CONSTITUTION: A peristaltic pump unit(30) comprises a first gear(32), blocking members(34), and a supporting member. The first gear comprises sawtooth, which engages with a driving source. The blocking members press a first transport tube to a blocking face and are respectively mounted on a first shaft. One end of the first shaft is mounted on the first gear. The support member is connected to the facing end of each shaft. A peristaltic pump comprises a housing, a motor, a worm gear, and a peristaltic pump unit. The housing forms a machine compartment and blocking surfaces. The worm gear is rotated by the motor. The peristaltic pump unit is rotatably arranged in the machine compartment.</p> |
