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.

Claims

1. 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 pushing a pushable handle, releasably coupled with said infusion device base and configured to release a driving spring to insert an infusion needle into said infusion site when pushed toward said skin surface;

further pushing said pushable handle to release said pushable handle and said spring from said infusion device base when pushed further toward said skin surface, and leaving at least said needle with said infusion device base upon completed pushing;

and

connecting a cover of a fluid connector assembly to said infusion device base via placement using a motion perpendicular to a skin surface.

2. A method as claimed in claim 1, further comprising the step of:

connecting a slide with said cover to secure said cover to said infusion device base via placement using a motion parallel to said skin surface, wherein a tube is connected to said slide.
