PROBLEM TO BE SOLVED: To provide a catheter tube which is more kind to the patient's skin in a fistula region, is more fitted when employed as a fistula catheter, and is capable of making the total time duration for each dialysis shorter.SOLUTION: A catheter 2 is composed of a tube piece formed of a plastic material, and the rear part of the catheter 2 is extended short or connected to the distal portion of a hub 4. A cannula 3 in the form of a tubular needle made of metal, extends to a straight passageway and the catheter 2 so that the sharp end of the cannula 3 is projected short to the front of a front end of the catheter 2, and by allowing the cannula 3 to be pulled out to the back from the hub 4, a connection part between the catheter 2 and a branch conduit is established. Also, the distal portion 11 is provided with a pair of wings 29 extending from the hub 4, and the wings 29 are folded aganist one another in order to serve as a gripping member 7 when the catheter is being inserted into a fistula, wherein they can be brought to contact and be releaseably adhered to the skin of a patient in order to fix the catheter 2 thereafter.【課題】瘻孔領域の患者皮膚により優しく、瘻孔カテーテルとして使用する場合良くかみ合い、透析毎の全継続時間を短縮できるカテーテルチューブを提供する。【解決手段】カテーテル２がプラスチック材でできたチューブ片からなり、カテーテル２後部がハブ４の遠位部に短く延びるか接続され、管状金属ニードル形状のカニューレ３が、カニューレ３の鋭い末端がカテーテル２前端の前方に短く突き出すように真っ直ぐな通路とカテーテル２に延び、カニューレ３がハブ４から後方に引き出せることにより、カテーテル２と分岐導管間の接続部が確立され、且つ、ハブの遠位部１１がハブ４から延びる一対の翼２９を備え、カテーテルを瘻孔に挿入する必要がある場合、翼２９を互いに折りたたんで把握部材７として働き、その後カテーテル２を固定するために患者の皮膚に接触又は解除可能に取り付けられる。【選択図】図１
