PROBLEM TO BE SOLVED: To provide a transfusing pump which can completely press and close fluid in the inside of a guiding part even if a transfusing tube is widened right and left when the transfusing tube set in the inside of the guiding part of the transfusing tube is completely pressed and closed by fingers at the upstream and downstream sides, and is excellent in accuracy because the thickness of the transfusing tube is made free from an adverse effect on its function by letting the tube be pressed and closed to its halfway by means of other fingers. SOLUTION: It is so constituted that, in this transfusing pump where fluid is fed by pressing the outer circumferential surface of its transfusing tube, each finger to be individually driven, is referred to as a first finger 10-1, and second fingers 10-2a and 10-2b respectively for places starting from the upstream side, to which fluid is fed, and is also referred to as a N-th finger 10-4 for the downstream side, the first finger 10-1 and the N-th finger 10-4 are individually driven in such a way that the transfusing tube is completely pressed and closed, however, the other fingers are individually driven in such a way that the transfusing tube is not completely pressed and closed, and concurrently, a finger housing part 101 holding the transfusing tube and a receiving plate 130 disposed in response to the finger housing part, are provided. In this case, each width size W1 of the first finger 10-1 and the N-th finger 10-4 is set to be larger than each width W2 of the other fingers. |
