    Abstract: The subject invention provides a safety pen needle assembly which includes: a hub; a needle carrier; a needle fixed to the needle carrier; a shield; and, a first engageable locking arrangement for fixing the shield to the needle carrier. Upon a predetermined extent of distal movement of the shield relative to the hub, the first locking arrangement is engaged such that the shield becomes fixed to the needle carrier. Upon further distal movement of the shield relative to the hub beyond the predetermined extent of distal movement, the shield and the needle carrier move in concert together relative to the hub causing a proximal end of the needle to move distally relative to the hub to a retracted state. Advantageously, the subject invention provides a reliable, low-cost safety pen needle assembly which does not require a spring or other biasing element.

    Abstract translation: 本发明提供了一种安全笔针组件,其包括:轮毂; 针架; 针固定到针架上; 盾牌 以及用于将屏蔽件固定到针架上的第一可接合锁定装置。 在护罩相对于毂的预定程度的远端运动中,第一锁定装置被接合,使得护罩固定到针架上。 当护罩相对于轮毂进一步远离移动超过远程运动的预定范围时,护罩和针托架相对于轮毂相互一起移动,使得针的近端相对于轮毂向远侧移动到缩回 州。 有利地,本发明提供了一种可靠的低成本安全笔式针组件,其不需要弹簧或其它偏置元件。
