<p>The invention relates to a body-insertable conduit comprising: a tube expansion unit which has a tube shaped cross section and in which a fluid flow space and a tube expansion space are separated by the tube shaped cross section wherein the tube expansion is formed to surround an outer side of the fluid flow space; and an insertion guide unit installed in an outer side of the tube expansion unit along a direction of a body insertion and keeping the tube expansion unit arranged in the direction of a body insertion wherein the conduit is inserted into a body in a state that a diameter of the conduit is reduced by the tube expansion space which is contracted and the diameter of the conduit is enlarged by expansion of the tube expansion wherein the expansion is made by flowing the fluid to the tube expansion space, and the fluid flows to the body from the fluid flow space or the fluid flows to the fluid flow space from the body. Accordingly, the conduit is inserted into the body in a state that the tube expansion unit is contracted and the original diameter of the conduit is formed by expansion of the tube expansion unit after the insertion, thereby relieving a patient′s pain generated when the conduit is inserted into the body.</p> |
