<P>PROBLEM TO BE SOLVED: To provide a reservoir instrument for easily inserting a catheter or the like into a blood vessel. <P>SOLUTION: The reservoir instrument 100 is provided with: an indwelling tube 130; a reservoir main body 110; and a tightly sealing cover 120, and the indwelling tube 130 is flexible and at least the distal end is indwelt inside the blood vessel. In the reservoir main body 110, a discharge port 113 connected to the end of the indwelling tube 130 and an inlet 112 facing the body surface are communicated to an internal space and it is indwelt inside the body. The tightly sealing cover 120 is flexible and tightly seals the inlet 112 of the reservoir main body 110. Since the internal space of the reservoir main body 110 is formed in a tapered shape smoothly communicating the inlet 112 and the discharge port 113, the catheter and a guide wire inserted into the inlet 112 are smoothly guided to the discharge port 113, and thus the catheter 141 or the like can be easily inserted from the reservoir device 100 into the blood vessel. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
