提供了一种医疗针屏蔽装置，其包括具有第一段和从其延伸的第二段的可扩展屏蔽。第二部分包括开口，其配置用于在将可扩展屏蔽连接到医疗针装置期间清除医疗针装置的医疗针。所述第二段定义与其远端部分相邻的平面。所述平面被配置成使所述针啮合以将所述屏蔽置于延伸位置。在替代实施例中，医疗针屏蔽装置具有具有支撑针的针毂的注射器。第一节从布置在针毂周围的接箍上铰接。领子上有一对插销。所述开口被配置为围绕所述针移动，以方便将所述屏蔽从缩回位置延伸到伸出位置。所述第二节还包括与所述针接合以促进所述屏蔽的延伸的近端支点。第二部分也有一对捕获物。擒抱器与闩锁接合，使护罩保持在缩回位置。所述第二部分具有定义为使所述针接合以方便将所述屏蔽固定在所述延伸位置的平面的鼻部。
A medical needle shield apparatus is provided which includes an extensible shield having a first segment and a second segment extending therefrom. The second segment includes an opening configured for clearance of a medical needle of a medical needle device during attachment of the extensible shield to the medical needle device. The second segment defines a planar surface adjacent a distal portion thereof. The planar surface is configured to engage the needle for disposing the shield in an extended position. In alternate embodiment, the medical needle shield apparatus has a syringe having a needle hub supporting a needle. The first segment articulates from a collar disposed about the needle hub. The collar includes a pair of latches. The opening is configured for travel about the needle to facilitate extension of the shield from a retracted position to an extended position. The second segment further includes a proximal fulcrum that engages the needle to facilitate extension of the shield. The second segment also has a pair of catches. The catches are engageable with the latches to maintain the shield in the retracted position. The second segment has a nose portion defining a planar surface configured to engage the needle to facilitate fixing the shield in the extended position.
