Abstract
An infusion set has an adhesively secured main hub, and a slidable top cover, needle hub and angled or cantilevered needle that can be used for performing an intradermal needle insertion precisely targeting the upper 3 mm of skin surface, for example, one that substantially duplicates the Mantoux insertion technique, for injecting into the intradermal layers of skin, while maintaining a degree of comfort to the user. By sliding the top cover, the cantilevered needle is loaded and released or the angled needle is slid into an insertion site, while flexible arms and adhesive are used to stretch and/or flatten a skin surface, or otherwise create skin tension, at the insertion site.
