An ostomy device includes a first unit adapted to extend into the upstream section of the intestine and a second unit connected to the first unit and adapted to extend into the downstream section of the intestine. The first unit includes a first extension member that is hollow and is suitable for extending into the upstream section and has an inlet that communicates upstream, and a first extension member that integrally communicates with the first extension member and faces the radial side. The opening extends and has a communication member opposite to the lead-out port of the introduction port, and a first member formed on the first extension member and the outer surface of the communication member and suitable for increasing the frictional force with the intestinal tract. Raised pattern. The second unit includes a second extension member suitable for extension positioning at the downstream section, and a first extension member formed on the outer surface of the second extension member and adapted to increase the frictional force with the intestinal tract. Two convex patterns.一種造口裝置，包含一適用於伸置於腸道之上游段的第一單元，及一連接於該第一單元且適用於伸置於腸道之下游段的第二單元。該第一單元包括一呈空心狀而適用於伸置於該上游段中且具有一朝上游連通之導入口的第一伸置件、一個一體連通該第一伸置件且往該徑向側開口延伸並具有一相反於該導入口之導出口的連通件，及一形成於該第一伸置件及該連通件之外表面，且適用於增加與該腸道間之摩擦力的第一凸紋。該第二單元包括一適用於伸置定位於該下游段的第二伸置件，及一形成於該第二伸置件之外表面，且適用於增加與該腸道間之摩擦力的第二凸紋。
