    • A prefillable delivery device fro administering intradermal injections includes a prefillable container adapter to store a substance. The substrate is expelled through a needle cannula having a forward tip adapted to administer the intradermal injection. A limiter surrounds the needle cannula having a generally flat skin engaging surface extending in a plane generally perpendicular to the needle cannula. An insert is centrally located within the skin engaging surface and is piercable by the forward tip. A sleeve with a first end and a second end surrounds the prefillable container. The limiter is slidably inserted through the first end and the second end is affixed to a depressable pluger for expelling the substance form the container. The limiter is movable between a first position and a second position thereby exposing the forward tip an is selectively movable between a third position and a fourth position thereby concealing the forward tip.
    • 用于实施皮内注射的预先填充的递送装置包括用于存储物质的可预先填充的容器适配器。 基质通过具有适于施用皮内注射的前部尖端的针头套管排出。 限制器围绕针套管,该针套管具有在大致垂直于针套管的平面内延伸的大致平坦的皮肤接合表面。 插入件位于皮肤接合表面的中心并且可由前端刺穿。 具有第一端和第二端的套筒围绕可预先填充的容器。 限制器通过第一端可滑动地插入,并且第二端被固定到可压下的拔出器上,用于从容器中排出物质。 限制器可在第一位置和第二位置之间移动,从而暴露前部末端可在第三位置和第四位置之间选择性地移动,从而隐藏前部末端。
