摘要：
A needle hub assembly for a pen needle includes a needle hub, an inner shield and an outer cover. The open end of the outer cover is closed by a removable seal to access the needle hub. The needle hub has a body with a shoulder and a tower extending from the body for supporting a cannula. The inner shield fits over the tower and the cannula and includes a flange that has an outer dimension complementing the outer dimension of the needle hub and contacts the shoulder of the needle hub in the assembled condition. The outer cover encloses the needle hub and the inner shield and includes a stop member on an inner surface that contacts the flange of the inner shield to capture the inner shield between the shoulder of the needle hub and the outer cover.
