Benefits of technology

The present invention is a pen needle assembly with an outer cover that can be safely discarded after use. The needle hub and cannula can be inserted into the needle hub well after use, reducing the risk of inadvertent needle stick. The outer cover with the retained needle hub can be safely discarded. The technical effects of this invention are improved safety and ease of use for pen needle assemblies.

Problems solved by technology

During the placement back into the outer cover, the cannula is exposed and provides an increased risk of accidental needle stick.
The manual operation of holding the outer cover while positioning the spent needle hub and cannula into the cavity of the outer cover can be difficult without accidental needle stick.

Abstract

A needle hub assembly for coupling to a pen needle delivery device (10) includes an outer cover (30) having a first well (40) receiving the needle hub (16) and inner shield (24) covering a cannula (20) of the needle hub (16). A second well (42) is spaced from the first well (40) and has a dimension for receiving the inner shield (24). In use, the pen delivery device (10) is coupled to the connecting end of the needle hub (16) to withdraw the needle hub (16) and inner shield (24) from the first well (40). The inner shield (24) is inserted into the second well (42) where the inner shield (24) is gripped so that the inner shield can be separated from the needle hub (16) without the user handling the outer cover (30) or the inner shield (24). After use, the needle hub (16) is inserted into the first well (40) and the pen needle delivery device is separated from the needle hub (16). The needle hub (16) is retained within the first well (40) where the outer cover (30) containing the used needle hub and inner shield can be discarded as a single unit.

Description

[0001]This application is a continuation application of U.S. Ser. No. 16 / 465,753, filed on May 31, 2019, which is a national stage application of PCT / US2017 / 064706, filed on Dec. 5, 2017, which claims priority under 35 USC § 119(a) from Chinese Utility Model Application No. 201621333821.8, filed on Dec. 6, 2016, and Chinese Invention Patent Application No. 201611110864.4, filed on Dec. 6, 2016, which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to a pen needle assembly having an outer cover forming an enclosure for the pen needle. More particularly, the present invention generally relates to an outer cover having a first well to retain a needle hub having an inner shield and to retain the needle hub after use to reduce the risk of inadvertent needle stick. The outer cover has a second well to receive the inner shield for separating the inner shield from the needle hub without the need to handle the inner s...
