<;P>;PROBLEM TO BE SOLVED: To provide a fluid transplanting device that realizes the downsizing and thinning and can be equipped in vivo. <;P>;SOLUTION: The fluid transporting device 1 is for allowing fluid to flow continuously by pressing tube 50 and has a fluid transporting mechanism 2 having the first cum 20 for pressing the fingers 40 to 46 in order to block the tube 50 and the second com 30, a driving power transmitting mechanism 3 that transmits the driving power to the fluid transposition mechanism 2, a reserver 60 connecting to the tube 50, a valve (port) 80 for filling the fluid into the reserver 60, and a cell 4 for feeding electric power to the drive power emitting mechanism 3 wherein the fluid transporting apparatus 2 and the driving power emitting mechanism 3 are arranged so that they may be overlapped, and the fluid transplanting mechanism 2 and the reserver 60 is arranged on the position so that it may not overlapped to the liquid transplanting mechanism and the drive power transmitting mechanism 3. Finally, at least the fluid transplanting mechanism 2, the drive power transmitting mechanism 3, and the cell 4 are housed in the sealed space formed with the outer case made of the upper lid 13 (Fig.1) and the lower lid 16 (Fig.1). <;P>;COPYRIGHT: (C)2009,JPO&INPIT
