Abstract
An infusion set has an integrated ballistic inserter that can insert a needle at a controlled high rate of speed to a depth to deliver content to the upper 3 mm of skin surface, and a skin securing, adhesive layer to secure the skin surface at the insertion site such that the inserter that can insert a needle without a risk of tenting of the skin surface. A driving spring of the ballistic inserter is captured within the ballistic inserter, and can be released by user operation, to insert a needle at such a controlled rate of speed.
