し、その内腔な閉塞しまうことがある。It is publicly known. Conventional multi-limbed catheters have multiple independent lumens that do not communicate with each other within a single tube body, and these lumens are used to continuously administer nutrient solution. The drug solution can be administered intermittently. The lumen used for administering nutrient fluids always has a flow and no blood flows into it, but for lumens used for intermittent administration, administration is often interrupted. During this time, blood may flow into the lumen and clot there, obstructing the lumen.

提供する。To achieve this objective, the present invention provides a multi-limb catheter that includes a single tube body having multiple branch tubes constituting multiple lumens, for continuously supplying fluid from the outside into the body. Connect the main branch pipe to be used to at least one other sub-branch pipe, cut off communication between the main branch pipe and the lumen on the proximal side of this sub-branch pipe, and connect the main branch pipe and this sub-branch pipe to the connected part. It is possible to communicate with the distal lumen of the branch pipe, and furthermore, it is possible to completely cut off communication between the main branch pipe and the secondary branch pipe, and at this time, fluid is not allowed to enter the body through this secondary branch pipe. A multi-limb catheter is provided, characterized in that it is provided with valve means that enable supply.

It also flows continuously into the pipe,
Since it flows into the body from there, blood will not flow into the secondary branch duct even when the drug solution is not being administered through the opening of the secondary branch duct.
血液の凝固による閉塞を防止できる。It can prevent blockages caused by blood coagulation.
［実施例］
以下、添付図面を参照しながら本発明を実施例によって
説明する。[Examples] Hereinafter, the present invention will be described by way of examples with reference to the accompanying drawings.

開口端に取り付けである。In the illustrated embodiment, the branch tube 10 shown on the right side of FIG. 1 is the main branch tube used to continuously administer liquids, for example, maintenance nutrient solutions, and the left branch tube 12 is used to administer medicinal solutions intermittently. It is used as a secondary branch pipe for In addition, since the amount of maintenance nutrient solution that is usually administered is larger than that of other drug solutions, it is preferable that the flow area of the main branch pipe 1O is larger than the flow area of the secondary branch pipe 12.
As can be seen in FIG. 1, both branches 1O112 each have a cap 16.18 attached to the open end when not in use.
