Abstract
An infusion set has a partially integrated ballistic inserter that can insert a needle at a controlled 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 with a reduced risk of tenting of the skin surface. A removable turnkey or pushable handle can be provided to release a driving spring of the ballistic inserter to insert a needle at a controlled rate of speed, of 3.3 ft/sec. (1.0 m/sec.) up to and including those greater than 10 ft/sec. (3.0 m/sec.), then release from the set for disposal. The infusion set can further include an extendable interface ring that retracts when the inserter is removed from the infusion set.
