PURPOSE:To enable the easy and rapid completion of hemostasis after removal of a tube introducing device for medical treatment by using the pricking section closing material which closes the pricking section of a vessel after the closing material is inserted into the vessel by means of the introducing device and the introducing device is removed from the vessel. CONSTITUTION:This pricking section closing material 1 is inserted into a sheath 13 and is pushed by a pushing shaft 4. The hard part 2 of the closing material 1 is pushed and bent by the inside wall of the sheath 13 and is held in a folded state. The hard part 2 rises as if an umbrella opens to form the umbrella-like closing material 1 when the closing material 1 is pushed down to the inside of the blood vessel 12 and the pressure on the hard part 2 by the inside wall of the sheath 13 is released. The umbrella-like closing material 1 is pressed to the inside wall of the blood vessel 12 and is pressed to the inside wall of the blood vessel 12 by a blood pressure when the pushing shaft 4 is slightly drawn out together with the sheath 13 in this state. The closing material eventually closes the removed hole by drowing out the sheath 13. As a result, the hemostasis after the removal of the tube introducing device for medical treatment is easily and rapidly completed. |
