| 摘要 |
The invention relates to an injection device (1), especially for bone cement , comprising A) a syringe base (3) having a longitudinal axis (2), a front end (6), a connecting piece (8) disposed on the front end (6) and having a coaxi al bore (21), and a coaxial cavity (4); B) an injection plunger (5), coaxially displaceable in the cavity (4); and C) a cannula (13) which can be linked wi th the connecting piece (8) and which has a center bore (14) and a rear end (15 ). The injection device is characterized in that D) the syringe base (3), on it s front end (6), has a transition segment (22) having a bore (9) linking the cavity (4) with the bore (21) in the connecting piece (8), E) the bore (9) i n the transition segment (22) and the center bore (14), at least on the rear e nd (15) of the cannula (13), having the same orthogonal cross-sectional area q relative to the longitudinal axis (2).
