COMBINED CONTAINER-SYRINGE

摘要

A combined container-syringe is provided. A bypass chamber and front chamber is provided at a cylindrical tip. The bypass chamber has an inner diameter greater than the outer diameters of front and rear stoppers. The front stopp er is inserted into the bypass chamber. The front chamber has an inner diameter equal to the inner diameter of a cylinder or not greater than the outer diameters of the front and rear stoppers and has a volume greater than the volume of a drug solution. A bypass groove is formed in the inner wall of the bypass chamber and allows the cylinder to communicate with the front chamber while bypassing the front stopper. Accordingly, it is possible to provide a combined container-syringe enabling observation of the condition of a drug solution filled therein before making an injection and thus to make an injection in a secure manner.
