Reduced-pressure syringe and manufacturing method therefor |
摘要 |
A-syringe for storing a freeze-dried agent therein under reduced pressure as well as a method for manufacturing the syringe. A specified amount of a chemical is injected into a cartridge with the one end of the cartridge down. The gasket is plugged halfway on the other end side of the cartridge, so that the cartridge is made communicating between inside and outside by the recessed groove, in which state the chemical is freeze-dried. The sealing cap is overlaid on an upper end face of the gasket and the sealing cap is pushed in the reduced-pressure atmosphere so that the other end side of the cartridge is sealed by the gasket and the sealing cap. The sealing cap is engaged with an end face of the cartridge on the other end side, thereby being prevented from moving into the cartridge.
