Claims

[Scope of utility model registration request]

(1) Fluid transport tube and this fluid transport tube-5
and a fastening tool for tightening the fluid transport tube to the cap, and the cap has a tube fitting portion formed on the protruding tip side thereof, and a tube fitting portion of the tube fitting portion. The more proximal part has a hook engaging part consisting of a small diameter step on the proximal side, and the tightening tool has a ring-shaped tube restraint part and extends from this tube restraint part in the axial direction. The tube suppressing part is composed of an elastic leg part that can be extended and elastically spread in the radial direction, and a hook part that projects inward in the radial direction at the extending end of the elastic leg part and can be engaged with the hook engaging part. The distance between the tube and the hook part shall be set to a size that allows the tube holding part to tighten and secure the tube fitted into the tube fitting part when the hook part is locked to the hook engaging part of the cap. A connecting device for fluid transport tubes in a medical device, characterized by:

(2) Utility Model Registration Scope of Claims In the device for connecting a fluid transport tube in a medical device as set forth in claim 1, the cap is located on the proximal end side of the hook retaining portion and is a jig for locking a jig. A connecting device for a fluid transport tube in a medical device, characterized in that an engaging portion is formed, and the tightening is performed by forming a jig engaging portion for locking a jig to a tool as well.

(3) In the connection device for a fluid transport tube in a medical device as set forth in claim 1 or 2 of the utility model registration claim, the elastic legs of the tightening device are capable of tightening the cap when attached to the mouth. Fluid transport in a medical device characterized by having a gap between the outer periphery of the device and the hook portion that can be deformed enough to separate the hook portion from the hook engaging portion of the cap when crushed radially inward from the outer periphery side. Tube connection device.
