A tubular housing (1) having a first opening (11) at one end and a second opening (13) at the other end, in which a membrane tube (31) to be released is installed； An open body (2), which is installed at one opening (11) and connected to one end of the membrane tube (31) and is made of a material that can be digested and absorbed by the intestinal tract of the human body, is sequentially put on and relatively moved to each other. A possible inner tube (41), middle tube (42) and outer tube (43), a part of the inner tube (4) being located in the housing (1) and connected to the release body (2), A stopper piston (12) located inside the housing (1) is fixedly mounted outside one end of the tube (42), and the outer tube (43) is located outside the housing (1), and one end of which is a second opening. (13) fixed An inner tube (41), a middle tube (42), and an outer tube (43) are connected to each other, and the inner tube (4) and the middle tube (42) are operated so that both move in the axial direction. A device for releasing an intestinal isolation membrane tube for detaching the release body (2) from the housing (1) and releasing the membrane tube (31) from the housing to release the intestine at a predetermined position in the human intestine. The release device has a simple structure, low manufacturing cost, easy operation, high reliability, does not cause a wound when implanted in a human body, and has no toxicity or side effects on the human body.一端に第１開口（１１）を有し、他端に第２開口（１３）を有し、内部に解放対象の膜チューブ（３１）が設置されている管状のハウジング（１）と、該第１開口（１１）に設置されるとともに膜チューブ（３１）の一端に接続され、人体の腸管により消化して吸収可能な材料で製造された解放体（２）と、順次套設され互いに相対移動可能なインナーチューブ（４１）、ミドルチューブ（４２）及びアウターチューブ（４３）であって、インナーチューブ（４）の一部がハウジング（１）内に位置し解放体（２）に接続され、ミドルチューブ（４２）の一端外にハウジング（１）内に位置するストッパーピストン（１２）が固定して套設され、アウターチューブ（４３）がハウジング（１）外に位置し且つその一端が第２開口（１３）に固定して接続されるインナーチューブ（４１）、ミドルチューブ（４２）及びアウターチューブ（４３）とを備え、インナーチューブ（４）及びミドルチューブ（４２）を両方が軸方向に移動するように操作して、解放体（２）をハウジング（１）から脱離させ、且つ膜チューブ（３１）をハウジングから脱出させ、人体の腸管の所定位置で解放する腸管隔離用膜チューブの解放装置。該解放装置は、構造がシンプルで、製造コストが
