SOLUTION: In the state of connecting a tube 4 with a capsule 3 by putting a cord-shaped member 6 extending through the inside of the hollow part of the tube 4 through a through-hole formed at the capsule 3, the capsule 3 is swallowed. Then, the speed of moving of the capsule in the esophagus 55 is set to a speed suitable for the inspection on the hand side of the tube 4, a dyeing test is performed by pouring an iodine solution 43, and a pulling-back test is performed as needed. In the stomach 57, a wide area can be inspected by pushing/pulling the cord-shaped member 6, twisting the tube 4, etc. so as to vary the direction of a visual field. Thereafter, it is possible to inspect the side of the deep part with the capsule 3 detached from the tube 4 by pulling one side of the hand side of the cord-shaped member 6.

| PURPOSE: To curve a flexible tube into a small diameter, by constituting the flexible tube so that the gap of a spiral tube satisfies a specific value in such a state that the flexible tube is straight. CONSTITUTION: The width of each of the plates 6b each having a thickness (t) forming the spiral tube 6 of a flexible tube 5 is set to (l) and the gap between the plates 6b is set to (s) while the inner diameter of the flexible tube 5 is set to (d) and the outer diameter of a skin 8 is set to D. The length L1 of the center line of the flexible tube 5 when said tube is formed into a semicircle having a radius r-30mm is π(30+D/2) and the number (n) of the widths (l) of the spiral tube 6 present within the length L1 when the flexible tube 5 is in a straight state are π(30+D/2)/(l+2). The axial length L2 of the spiral tube 6 of the radius R formed by the outermost diameter part of the spiral tube 6 corresponding to the length L1 is π(30+D)/2-d/2-t). At the time of L2>ln, the width (l) is present at a gap s≥0 within the length L2. That is, S≥l(d/2+t)/(30+D2-d/2-t) is formed. When the flexible tube 5 is bent, 3≥s(mm) is formed so as not to allow a net tube 7 to fall into the gap (s). COPYRIGHT: (C)1988,JPO&Japio | ||||||

| An endoscope system sets a hardness variation of a thick flexible tube portion and a hardness variation of a thin flexible tube portion such that their respective ratios against base hardness are constant, and as each flexible tube portion becomes thicker, the hardness variation increases and an endoscope with a relatively thin flexible tube portion has a smaller hardness variation. This makes it possible to avoid situations like an endoscope with a thick flexible tube portion lacking hardness or an endoscope with a thin flexible tube portion becoming too hard, and makes it possible to perform optimum insertion operation in accordance with the thickness of a flexible tube. | ||||||
