<P>PROBLEM TO BE SOLVED: To provide a combined container-syringe for effectively eliminating air-bubbles in a drug solution by air-eliminating work. <P>SOLUTION: The combined container-syringe includes a bypass chamber 25 which is arranged in the front side of a fitting hole 24 of a needle hub 20 and to which the distal end of a front stopper 10 is inserted and liquid-tightly fitted. A plurality of bypass grooves 26 are arranged on the inner wall surface of the bypass chamber 25 and an annular groove 27 for connecting the grooves 26 is also arranged. A plurality of air-bubble introducing grooves 13 opening in a rear end surface and extending to the distal end are formed on the outer circumferential surface of the front stopper 10. When the distal end of the front stopper 10 is inserted to the bypass chamber 25, the air-bubble introducing grooves 13 are connected to the annular groove 27. <P>COPYRIGHT: (C)2010,JPO&INPIT |
