PURPOSE: To effectively avoid infection and accident by inserting a blunt sealed cannula into a re-sealable opening, making possible or remove the cannula while fluid path and insertion through are available, and providing a mobile means which mutually works with a housing so as to be re-sealed on this occasion. CONSTITUTION: The injection site has a cylindrical housing 14 through which the fluid path 16 passes, and a first edge part 18 is covered with a member 20 which has in its inside the re-sealable opening 22 comparatively thin rounded and re-sealable. This is a molded parlision wall which has a skirt 20a integrally formed, the cannula 12 includes a body part 24 which supports a hollow cylindrical dull piercer member 26 on first edge 18, and the member 26 slideablely adapts to the opening 22 when the cannula 12 is moved toward the first edge part 18 of the injection site. The mobile syringe means 20 transforms adjoining the opening 22, and the member 26 extends into the fluid path 16. A fluid path is connected to the fluid path 16 via the hollow piercer member 26. |
