<P>PROBLEM TO BE SOLVED: To provide a peristalsis type transfusion apparatus with reduced size and weight wherein driving force of a cam driving means is reduced by making the power of holding a transfusion tube by a pressing plate and fingers of the most upstream side and the most downstream side of delivery approximately equal to the holding power of the other fingers. <P>SOLUTION: The peristalsis type transfusion apparatus includes two or more fingers 10-n and the pressing plate 70 supported by a door 4, wherein the transfusion tube 2 is held between the two or more fingers and the pressing plate, and the content of the transfusion tube is delivered in a direction of peristaltic motion by the peristaltic motion to successively press an outer peripheral surface of the transfusion tube. The pressing plate is swingably supported by the door with two or more compression coil springs 40 and longitudinal dimensions along the peristaltic motion of at least the fingers of the most upstream side and the most downstream side of the delivery are made smaller than the longitudinal dimensions of the other fingers. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
