INSULIN PUMP DERMAL INFUSION SET HAVING PARTIALLY INTEGRATED MECHANIZED CANNULA INSERTION WITH DISPOSABLE ACTIVATION PORTION

摘要

PROBLEM TO BE SOLVED: To provide an infusion set that can deliver a drug to a skin surface that facilitates superior absorption of the drug, and can also maintain a certain degree of comfort for a user.

SOLUTION: The infusion set has a partially integrated ballistic inserter that can insert a needle at a controlled speed to a depth to deliver a content to the upper 3 mm of the skin surface, and a skin-securing adhesive layer to secure a skin surface at an insertion site such that the inserter can insert the 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 the needle at the controlled speed of 3.3 to over 10 ft/sec. and subsequently 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.
