Abstract
A hard-packaged safety needle device comprises a needle hub having a needle cannula extending therefrom and a hard needle enclosure including a needle cover and a cap. The needle cover has an elongated body and a ribbed surface configured to create an interference fit with a proximal portion of the hub. The cap includes a body having an open distal end, a closed proximal end, and a cavity defined by the open distal end and the closed proximal end, the open distal end of the cap abutting an open proximal end of the needle cover.
Claims12
A hard-packaged safety needle device comprising:
- a needle hub, configured to couple to a syringe, comprising a distal portion and a proximal portion, wherein a plurality of longitudinal ribs extend from the distal portion of the needle hub;
- a needle cannula extending from the distal portion of the needle hub;
- and
- a hard needle enclosure including a needle cover and a cap, the needle cover having an elongated body, a cavity defined by an open proximal end and a closed distal end, a proximal portion, a medial portion and a distal portion, the proximal portion having a surface configured to mate with the cap, the medial portion being defined by a flange extending from the elongated body, the elongated body further having an inner surface of the cavity having a proximal inner surface, a medial inner surface, and a distal inner surface, the proximal inner surface including a ribbed surface configured to create an interference fit with the proximal portion of the needle hub, the medial inner surface including a plurality of protrusions configured to interdigitate with the plurality of longitudinal ribs of the needle hub, wherein each of the plurality of longitudinal ribs nest between two of the plurality of protrusions preventing rotational movement of the needle hub,
- the cap including a body having an open distal end, a closed proximal end, and a cavity defined by the open distal end and the closed proximal end, the open distal end of the cap abutting the open proximal end of the needle cover, the proximal portion of the needle hub, the cap and at least a portion of the needle cover are covered by a removable sleeve which holds the cap and the needle cover together.
