1. An improved venipuncture device comprising:
- catheter means having catheter hub means attached thereto at a first end;
needle means having needle hub means attached thereto at a first end and a sharpened tip at a second end, said needle means extending coaxially through said catheter means with said sharpened tip extending from said catheter means at a second end and being adapted for insertion and removal from said catheter means; and
a fin member extending substantially vertically from said needle hub means and longitudinally along a substantial portion of the length of said catheter hub means whereby said device may be easily grasped, balanced and manipulated during venipuncture;
guide track means longitudinally disposed along the exterior of said catheter hub, along the base portion of said fin member and along said needle hub, said guide track means being constructed and arranged for the slidable attachment or detachment of said needle hub means to said catheter hub means, said guide track means further being effective to prevent rotation of said needle means within said catheter means;
said base portion of said fin member being disposed coaxially with and extending vertically from said guide track means so as to facilitate kinesthesis, ease of venipuncture, and joinder or separation of said catheter hub means from said needle hub means by means of said fin member.

Abstract
An improved venipuncture device comprises a catheter having a catheter hub at one end, with a needle having a needle hub at one end and a sharpened tip at the second end extending through the catheter and catheter hub. The needle is adapted for insertion and removal from the catheter. A fin extends substantially vertically from the needle hub and is constructed and arranged for gripping the device in a manner which facilitates venipuncture.
