1. An infusion set adapted to be secured to a skin surface, comprising:
- a fixed base member connectable to the skin surface;
a movable member having a needle or cannula connected thereto and movable relative to said fixed base member, said movable member being movable from a first position in which said needle or cannula is not exposed externally of said fixed base member to a second position in which a distal portion of said needle or cannula is exposed externally of said fixed base member; and
a release member retaining said movable member in said first position, complete removal and disconnection of said release member from said infusion set triggering movement of said movable member to said second position, said removal and disconnection of said release member from said infusion set occurring in a direction substantially perpendicular to said skin surface;
whereinwhen said movable member is in said first position, the distal portion of said needle or cannula is disposed at a non-perpendicular angle with respect to said skin surface.

Abstract
An infusion set adapted to be secured to a skin surface includes a fixed base member connectable to the skin surface and a movable member. A needle or cannula is connected to the movable member and movable relative to the fixed base member. The movable member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A release member retains the movable member in the first position. Removal of the release member allows movement of the movable slide member to the second position.
