カテーテルが用いられるが、Ｔ字型カテーテルには従来
このような装置を（１１ｈえたものｉｌｌなかった。(1) Conventional technology Catheters are used for collecting body fluids, injecting drugs and contrast agents, etc., and are inserted into the human body percutaneously, or by open surgery on the Φ region. It is done by including
The catheter may be indwelled in the human body for a considerable period of time, and the method of use (J) is not necessarily uniform.Especially when indwelling the catheter in the human body, it may be necessary to fix the catheter in the required position or temporarily occlude the target organ. In order to do this, a so-called balloon catheter is used which is equipped with a device that can form a balloon on the catheter tube's 1 side, but no T-shaped catheter has ever been equipped with such a device.

Ｉできない不便があり、診療を制約する一因となってい
７：。(2) Problems to be solved When an R-shaped catheter is pushed into the biliary tract during surgery, for example, it was not possible to form a balloon-like object as described above, so it was necessary to fix it in the indwelling position. However, it was not possible to maintain stable indwelling in the human body. Also,
Of course, the inner diameter of the biliary tract and the diameter of the catheter tube are the same.
The drugs and contrast agents excreted during the treatment will be diffused into the biliary tract, and it is inconvenient that it cannot be temporarily retained in a specific area for GI, which is one of the factors that restricts medical treatment7. :.
のみならず、−１１カテーテル横デユープ外に排出され
た薬剤・造影剤が該チューブ内に逆流することを妨げる
ことができず、後に体液を採取するｌＪｉげともなって
いた。更に、カテーテル横チューブの一方からのノド薬
剤・造影剤を排出することはできない不便さがあった。In addition, it was not possible to prevent the drug/contrast medium discharged outside the lateral duplex of the -11 catheter from flowing back into the tube, resulting in a risk of collecting body fluid later. Furthermore, there is the inconvenience that the throat drug/contrast medium cannot be discharged from one side of the catheter lateral tube.
もし、その一方（例えば総胆管方向）からのみ排出でき

間隙を伝わって目的外の部位（例えば肝管方向）へ拡散
することを防くことができなかった。Even if the drug/contrast agent could be discharged from only one side (for example, the direction of the common bile duct), because the internal diameter of the bile duct and the diameter of the catheter tube are different, the drug/contrast medium would be discharged from one side. It was not possible to prevent this from spreading through the gap between the biliary tract and the catheter tube to an unintended site (for example, in the direction of the hepatic duct).

力、る。1) A main lunon and an air lumen are provided in the T-shaped tube in a ′[゛-shaped catheter having a portion of an I connector and an opening thereof, a plurality of check valve portions, and an opening thereof, and the end of the air lumen is A cylindrical outer balloon part is used to cover the dirt with a cylindrical outer balloon part, and both ends of the balloon part are fixed to the wall of the T-tube. A single-shaped type characterized in that the outer surface of the T-shaped tube is pierced with an air hole, the dirt is covered with an inner balloon part, and the surrounding area is fixed to the wall of the T-shaped tube. Balloon catheter 2) The F-shaped balloon catheter described in 1) is characterized in that the outer balloon part and the inner balloon part are made using different materials. This figure is a longitudinal cross-sectional view showing the feature of the present invention in which the features of the present invention are applied to a conventionally known F-shaped catheter having a part of a connector and a plurality of reverse IL valve parts. The T-shaped tube 1 is made of silicone rubber or the like, and has a main lumen 2 and a plurality of air lumens 4 formed therein. The air lumen 4 communicates with the connector part 9, the air lumen 4 communicates with the check valve part 11, and the opening 10 of the connector part communicates with each other.
For example, is there an opening 12 in the check valve part of a medical device for collecting body fluids or injecting drugs or contrast media? Each is connected to the IL transport main transport. The air lumen 4 has one air hole 5 at the top so that its end communicates with the outer surface of the T-tube 1, and this is covered with an outer balloon part G formed into a cylindrical shape using silicone rubber or the like. At the same time, both ends of the T-tube 1 are fixed to the walls of the T-tube 1, and an air hole 7 is penetrated so that the main lumen 2 and the outer surface of the T-tube 1 communicate with each other. 8 and cover it with T
Fixed to the wall of tube 1. As shown in this figure, the piercing position of the air hole 5 and the air hole 7 is such that when the fluid is fed into the air lumen 4 from the opening 12, the wind and moon 1)-shaped body formed by the outer balloon part 6 is inside. One method is to position the balloon portion 8 in a shape that encloses the balloon-like body, but depending on the type of organ to be treated and the purpose of the treatment,
Even if the respective positions are shifted from each other, 36 gill force is required.

If it is not preferable to simultaneously form a Fugetsu 1)-shaped body by feeding the II body, by creating each of them with +4 material as a boundary, the outer balloon part will form the Fugetsu [)-shaped body earlier than the inner balloon part. However, or vice versa, the present invention can be used for a wide variety of purposes.

できる。(5) Effects of the present invention According to the present invention, the T-shaped force tube inserted through open surgery can be stably placed (!7) and relocated (,1) by the outer balloon part. This prevents the injected drug/contrast agent from being temporarily expanded, and when necessary, the outer balloon part can be deflated and diffused by operating the check valve.On the other hand, the inner balloon part can be used to diffuse j-shaped tube
ir only the side that has been exposed! It can be used according to the clinical purpose over time, such as by occluding the other side, or by performing the opposite operation later to open the other side, and can be used for a long time in the human body. This point is particularly important because the function of the double-shaped catheter can be demonstrated in one minute.Replacing the single-shaped catheter with a lid and implanted is very invasive to the patient, so it can be done easily. In addition, by using different materials for forming the outer balloon part and the inner balloon part, it is possible to immediately respond to a wide variety of medical purposes as described above.
