Insulin Pump Dermal Infusion Set Having Partially Integrated Mechanized Cannula Insertion With Disposable Activation Portion
First Claim
1. An infusion device, comprising a partially integrated inserter that can insert a needle at a controlled rate of speed to a depth to deliver medicament to the upper 3 mm of skin surface, comprising:
- an infusion device base, comprising at least one adhesive layer for releasably securing said infusion device base with said skin surface; and
an inserter, wherein said inserter comprises an activation subassembly releasably secured to said infusion device base that is configured to release at least a user contact element and a driving spring from said infusion device base upon completed activation, and leave at least a needle with said infusion device base upon completed activation.

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.

20. An infusion device base for receiving a partially integrated inserter that can insert a needle at a controlled rate of speed to a depth to deliver medicament to the upper 3 mm of skin surface, comprising:
-
at least one adhesive layer disposed upon a bottom skin contact surface of said infusion device base for securing said infusion device base to an infusion site; at least one snap disposed upon a top surface of said infusion device base for releasably securing a partially integrated inserter; and an interface ring moveably coupled with said base, wherein said ring is configured to contact said partially integrated inserter and in response extend from said bottom skin contact surface of said infusion device base and to contact said skin surface, and move substantially flush with said bottom skin contact surface of said infusion device base when said partially integrated inserter is removed.

21. A method targeting a desired depth to deliver content to an upper skin surface, comprising the steps of:
-
placing an infusion device base upon an infusion site and activating a user contact element to release a driving spring to insert a needle into said infusion site; and further activating said user contact element to release said user contact element and said spring from said infusion device base upon completed activation, and leaving at least said needle with said infusion device base upon completed activation. - View Dependent Claims (22, 23, 24)
