Next, as shown in FIG. 3, the operator arranges the drive device D2 inserted in the cover member 20 on an operating table (not shown) or the like, and the proximal end portion of the diagnostic imaging catheter D1 is the drive device D2. Connect to.

As described above, the medical device 10 according to the present embodiment has a bag-shaped cover member 20 for inserting the drive device D2 used in the diagnostic imaging catheter D1 and a second cover member 20 arranged near the opening 21 of the cover member 20. It has one connection member 30 and a second connection member 40 that is attached to a storage unit D3 that stores the drive device D2 and that can be connected and separated from the first connection member 30.

According to the medical device 10, the first connection member 30 arranged near the opening 21 of the cover member 20 is attached to the second connection member 40 provided in the storage unit D3 in which the drive device D2 is stored. Be connected. Therefore, the operator can easily insert the drive device D2 into the cover member 20 while the cover member 20 is provided in the storage unit D3. Therefore, according to the medical device 10, the work from the removal of the drive device D2 to the insertion into the cover member 20 can be easily performed.

Further, the cover member 20 has a bellows shape that is folded back a plurality of times before use. Therefore, when the operator connects the first connecting member 30 to the second connecting member, it is possible to prevent the cover member 20 from coming into contact with a dirty field such as a floor.

Further, at least two first connecting members 30 are provided at positions separated from each other in the vicinity of the opening 21 of the cover member 20. Therefore, the operator can easily insert the drive device D2 into the cover member 20.

Further, the first connecting member 30 includes a hole 31 provided near the opening 21 of the cover member 20, and the second connecting member 40 includes a hook 41 that can be inserted into the hole 31. Therefore, the operator can easily connect and separate the first connecting member 30 and the second connecting member 40.
