Abstract
Manual insertion device has retraction spring () and hollow septum configuration () implemented using barrel-shaped guides () and a guiding boss () in insertion device housing (), and provides a fluid path through alignment of septum openings, side-port openings and catheter openings upon complete catheter insertion. Button () causes manual insertion of introducer needle () and catheter () of a first barrel () into a skin surface, and loading of retraction spring () disposed in an adjacent second barrel (). Once introducer needle () and catheter () are fully inserted, the introducer needle hub () is released and automatically retracted by release of the retraction spring (), leaving the catheter () in the user's body. Septums () and side-port openings () in the button () and introducer needle () are thus aligned, creating an uninterrupted fluid path between a reservoir or pump and catheter ().
