<p><P>PROBLEM TO BE SOLVED: To provide a valve cap for a retractor in which operability of the treating implement is improved while maintaining airtightness in a body cavity. <P>SOLUTION: The valve cap 1, mounted on the retractor 2 equipped with an inside fixing member 3, an outside fixing member 5, and an extension member 4, includes: a canopy member 8 in which a plurality of composite sheet members 12a and 12b consisting of first sheet members 10a and 10b and a second sheet member 11 are laminated; and a mounting member 9 hermetically mounting the canopy member 8 on the outside fixing member 5. The composite sheet members 12a and 12b are equipped with slit parts 13 and 14 penetrating through a pair of the first sheet members 10a and 10b and the second sheet member 11. The slit parts 13 and 14 of the adjoining composite sheet members intersect each other, and the first sheet members 10a and 10b have a higher lubricity than the second sheet member 11. On the second sheet member 11, when the treating implement is not inserted yet, the slit part 13 sticks hermetically, and the second sheet member 11 sticks hermetically on the treating implement when the treating implement is inserted. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
