<P>PROBLEM TO BE SOLVED: To provide a liquid medicine injection system with a prefilled syringe, which prevents liquid medicine from seeping out while charging a prefilled syringe into a syringe holder. <P>SOLUTION: The liquid medicine injection system comprises a prefilled syringe 11 to be charged into a syringe holder 16, in which liquid medicine is contained, and a gasket 14 packed in the prefilled syringe 11 to be pushed with a rod 12 for liquid medicine injection. A nail 18 to spread toward inside the syringe holder 16 and a cam 15 to lock up the prefilled syringe 11 charged into the syringe holder 16 are provided on a front end of the rod 12. When the prefilled syringe 11 is charged and its rear end pushes up the rod 12 to an inner tube 19 with the nail 18, the nail 18 narrows and the rear end of the prefilled syringe 11 is set in an annular airspace 17. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
