    摘要： A catheter and introducer needle assembly with a needle shield is provided. The needle shield includes a means for preventing unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a means for connecting the needle shield to the catheter hub until the sharp distal tip of the introducer needle has been withdrawn into the needle shield. Thus, when the distal end of the introducer needle extends from the distal portion of the needle shield, the needle shield is connected to the catheter hub and when the sharp distal end of the introducer needle is withdrawn into the needle shield, the needle shield is disconnected from the catheter hub. At that point, the sharp needle tip is secured within the needle shield.

    摘要： The luer adapter of this invention includes a barbed portion having a generally cylindrical distal portion, a generally conical portion, a generally cylindrical portion and a generally outwardly tapered proximal portion. The shape of the barb is substantially the same as the shape of the lumen at the proximal end of a catheter but is slightly larger radially and slightly shorter axially than the proximal portion of the lumen. This ensures that when the barb is inserted into the proximal portion of the lumen the luer adapter is positively locked to the catheter.

    摘要翻译： 本发明的鲁尔适配器包括有倒钩部分，其具有大致圆柱形的远端部分，大致圆锥形的部分，大致圆柱形的部分和大致向外的锥形的近端部分。 倒钩的形状基本上与导管的近端处的内腔的形状相同，但是比内腔的近端部分的径向略微更大的轴向稍短。 这确保了当倒钩被插入内腔的近端部分时，鲁尔适配器被积极地锁定到导管。
