摘要： A stylet for insertion within a cannula interior of a needle is disclosed. The stylet includes a solid elongated shaft having a proximal end adapted for engagement with a needle hub, and a distal end having a surface modified profile. The surface modified profile increases the penetration force required to penetrate human skin. The ratio of the penetration force of a stylet having an unmodified distal end to the stylet having a surface modified profile is at least 1:1.4, or greater. The surface modified profile may be a roughened surface, a buffed surface and/or a blunted surface. The surface modified profile may include a yieldable material disposed over at least a portion of the distal end. A needle assembly having a stylet having a surface modified profile is also disclosed.

摘要： A hub assembly, such as for long needles, is disclosed. The hub assembly includes a needle hub having a proximal end and a distal end, having a cannula extending therethrough and protruding from the distal end, with the needle hub having a first engagement portion. The hub assembly also includes a stylet handle having a stylet extending therefrom. The stylet is adapted to be received within a portion of the cannula, with the stylet handle having a second engagement portion. An engagement of the first engagement portion of the needle hub and the second engagement portion of the stylet handle forms a positive lock in which at least a portion of one of the first and second engagement portions is held within the other of the first and second engagement portions in an unbiased state.

摘要翻译： 公开了用于插入针的插管内部的探针。 探针包括具有适于与针座接合的近端的实心细长轴，以及具有表面改质轮廓的远端。 表面改性型材增加穿透人体皮肤所需的穿透力。 具有未修饰的远端的探针的穿透力与具有表面改性轮廓的探针的比例至少为1：1.4或更大。 表面改性型材可以是粗糙表面，抛光表面和/或钝化表面。 表面改性轮廓可以包括设置在远端的至少一部分上的可屈服材料。 还公开了具有具有表面改性轮廓的探针的针组件。
