An IV catheter introducer assembly including a catheter hub defining a chamber; a tubular member extending distally from the catheter hub having a length and defining a lumen, the lumen being in fluid communication with the chamber and configured to removably receive an introducer needle. The device also including a retention member disposed within the chamber having a body having a central lumen having a longitudinal length extending along a lengthwise direction to the length of the tubular member and sized to seal against an introducer needle. The retention member including a venting channel having at least a portion formed as a conic helix traversing a surface of the retention member along a radial path to the lengthwise direction.

Retention member and application thereof

The safety needle assembly includes a body and a wing assembly secured to the body. A grip is slidable along the exterior of the body, and a needle holder is slidable through an interior passageway in the body. The grip slides independently of the wing assembly, which is not slidable with respect to the body. The grip and the needle holder are secured to one another, so that sliding movement of the grip induces sliding movement of the needle holder. The grip and the needle holder are slidable between a distal position, in which a sharp distal tip of a needle held in the needle holder is exposed, and a proximal position, in which the sharp distal tip is not exposed.
