Abstract:
PROBLEM TO BE SOLVED: To provide a minute hollow projection tool with an aperture which can reduce pain and is hardly broken when puncturing the skin.SOLUTION: A minute hollow projection tool 1 is given in which a minute hollow projection part 3 that has an aperture 3h in the tip side and internal space formed connecting to the aperture 3h is projected from a base bottom member 2. When viewing any of longitudinal sections passing through an apex of the minute hollow projection part 3, wall thickness T1 of an apex side part TB in the apex side is thinner than wall thickness T2 of a lower side part BP in the base bottom member 2 side, and a gap M1c between inner walls 31, 31 at the apex side part TB is smaller than a gap M2c between inner walls 31, 31 at the lower side part BP. Curvature is given at a base part 34 of the minute hollow projection part 3 projecting from the base bottom member 2, and curvature is given at an inlet part 23 into the minute hollow projection part 3 on a rear face 25 opposite to a projecting front face 24 of the minute hollow projection part 3 in the base bottom member 2.SELECTED DRAWING: Figure 3
