Infusion device with releasable fluid connector

Abstract

An infusion set system includes a base and a fluid connector removably coupleable thereto. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

What is claimed is: 
     
         1 . A one-piece release liner having an interior opening therethrough, an external tab, and a single cut extending substantially radially from the tab only to the interior opening. 
     
     
         2 . The release liner according to  claim 1 , wherein the cut is substantially straight. 
     
     
         3 . The release liner according to  claim 1 , wherein the release liner is substantially circular and the interior opening is a central circular opening. 
     
     
         4 . A one-piece release liner for covering an adhesive, the release liner comprising:
 a flexible planar field portion having an interior opening therethrough, the field portion having a first measurement from a center of the field portion to a perimeter of the field portion; and   a tab portion contiguous with the field portion and extending a second measurement from the center of the field portion to a perimeter of the tab portion, the second measurement being greater than the first measurement the release liner having a single cut extending substantially linearly from the tab portion only to the interior opening.   
     
     
         5 . The release liner according to  claim 4 , wherein the release liner is substantially circular and the interior opening is a central circular opening.
