Abstract
Needle covers are provided for medical needle assemblies having a base and a cannula. The needle cover includes hub and cap portions. The hub portion is adapted to be secured to the base. The cap portion is adapted to substantially enclose at least a distal end of the cannula when the hub portion is secured to the base. The cap portion includes at least one generally outwardly extending wing having an outer edge and an enlarged rib extending along only a portion of the outer edge of the wing and only in a direction substantially parallel to a central axis defined by the cap portion. The cap portion is separable from the hub portion upon application of a torsional force, with the rib of the wing being thicker than the portion of the wing radially inward of the outer edge to assist gripping during application of such force.
