Pump means (2) transfer liquid in a liquid channel (12, 16) including a medical device (1). Motor means (4, 204) drive said pump means (2). Dial means operated by an operating unit adjust the number of rotations of said motor means (4, 204). First display means (5) display the number of rotations set by operating said dial means (24) by said operating unit when said pump means (2) is stopped. Detecting means dectect a real number of rotations of said motor means (4, 204) while said pump means (2) is driving ; and second display means (5) display the real number of rotations detected by said detecting means. Said operating unit operates said dial means based on the set number of rotations and the real number of rotations respectively displayed on said first and second display means, and adjusting the number of rotations of said motor means (4, 204). |
