Abstract
A needle assembly including a cover, an inner shield, a needle and a hub assembly is provided. After use, the cover is placed over the distal (patient) end of the needle and the inner shield can be used to cover the proximal (non-patient) end of the needle. The inner shield comprises flexible extensions above its open end to secure the inner shield over the proximal end of a needle in the needle assembly. A needle hub is also provided that eliminates adhesive bumps at the base of the needle and further distributes needle angular bending along an irregular surface, which facilitates proper insertion technique and effective needle length. The hub further includes stanchions or castellations on its edge such that when the patient uses proper injection techniques, the edges of the hub leave a distinctive impression in the skin of a user for a short period of time.
