摘要： Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. (As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector.) Alternatively, an iris-like structure may be incorporated into the front surface of the injector, for closing about the syringe upon insertion of the syringe into the injector.
摘要翻译：在前装载注射器中使用各种密封结构，用于防止溢出的流体从注射器的外表面泄漏到驱动柱塞的附近。例如，密封衬垫可以并入到注射器壳体的前表面中，用于与注射器的圆柱形主体的后圆形边缘配合。或者，密封和锁定功能可以通过注射器后端上的单个结构来执行。此外，可以通过在注射器上包括位于注射器前方的锁定结构的注射器上的非平面密封凸缘或包括注射器的两件式结构，以及用于将注射器包围的单独的泄漏停止垫圈来防止泄漏停止沿着注射器外部的流体流动。（作为该方面的一部分，或作为独立特征，注射器可以包括锁定结构前面的环形不连续的凸缘，用于为注射器提供针对注射器的机械支撑。）或者，可将虹膜状结构并入注射器的前表面，用于在将注射器插入注射器时围绕注射器闭合。
