Method and apparatus for safety catheter insertion device

An assembly comprising:

• a needle shaft having a first end, a second end, and a first dimension;
• a solid needle tip, said solid needle tip having a sharp end and a blunt end, and a groove, said blunt end having a second dimension that is greater than said first dimension to couple to said first end to form a juncture, said juncture being a step up from said first end, and said groove being disposed radially inwardly and running axially along a surface of said solid needle tip and extending from said sharp end to said blunt end;
• a catheter disposed about said needle shaft and said solid needle tip with said solid needle tip protruding from an edge of said catheter;
• and
• a connector to couple said catheter to a safety container which is partially disposed within a body, said safety container being designed to trap said needle tip therein after said solid needle tip retracts into said safety container.

A method comprising:

• coupling a one-piece needle shaft to a separate one-piece needle tip, said needle shaft extending between a first end and a second end, the first end having a first dimension, said needle tip having a sharp end, a blunt end, and a second dimension that is greater than said first dimension of the needle shaft such that said coupling forms a juncture that is a step up from said needle shaft first end to said needle tip blunt end;
• disposing a catheter about said needle shaft and said needle tip;
• and
• connecting said catheter to a safety container which is partially disposed within a body using a connector, said safety container being designed to trap said needle tip therein after said needle tip retracts into said safety container.
