PURPOSE:To obtain a tool in which insertion is easy and the contraception effect is high by forming the title tool by an elastic deformable material having a T-type shape essentially and forming the connecting part of a horizontal arm and a vertical shaft to an equilateral triangle wedge shape. CONSTITUTION:Respective two branches 4 with length about 2-5mm in the wedge shape to both edges of a horizontal arm 2 are extended. Thus, a sperm invasion can be prevented by the contraction of an in-womb muscle movement. The rod diameter of branches 4 may be about 1/2-1/4 of the diameter of the horizontal arm 2. At the time of the use, an inserting tube 10 to set an inserting tool is inserted into the womb from the womb cervix, a rod 11 is pushed, the inserting tool is pushed into the womb, the inserting tool is set into the womb and the inserting tube 10 is pulled out. Then, the horizontal arm 2 of the inserting tool is bent vertically to a vertical shaft 1 and becomes a T-type shape. After the use, when the arm is removed, a thread 9 is pulled out. At this time, since the horizontal arm 2 is easy to bend, the whole of the inserting tool becomes a rod-shaped and the womb cervix is not damaged. |
