Abstract
Abstract The needle patch has a Huber needle which is encased between a pair of flexible transparent discs. The needle has a depending angled portion which extends through an aperture in the lower disc for insertion in an implanted vascular access device. The lower disc also has an adhesive layer for securement to the skin about the injection site while the upper disc has a projection defining a reservoir above the aperture of the lower disc for dispensing of an antiseptic ointment to the injection site. A rigid housing is integrally formed with the discs to provide a finger gripping portion for insertion of the needle.
