Abstract

An IV catheter system may have a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a push feature protruding outwardly from the catheter hub. The IV catheter system may also have a needle component with a needle hub, a needle extending distally from the needle hub along an axis, and a grip extending from the needle hub, generally parallel to the axis, with a pull feature. In the insertion configuration, the needle may be positioned within the cannula and the distal end of the needle hub may be seated in a needle port of the catheter hub. In the fluid delivery configuration, the needle may be positioned outside the catheter hub. The push and pull features may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration to a fluid delivery configuration.

Claims (17)

1. An IV catheter system, comprising:

a catheter component comprising:

a catheter hub comprising a catheter hub distal end and a catheter hub proximal end;

a cannula extending distally from the catheter hub distal end; and

a wing coupled to the catheter hub, wherein the wing comprises a thinned portion forming a hinge; and

a needle component comprising:

a needle hub comprising a needle hub distal end and a needle hub proximal end; and

a needle extending distally from the needle hub distal end along a longitudinal axis; and

a grip extending from the needle hub, wherein the grip comprises a peripheral ridge positioned at an outer edge of the grip, wherein the grip further comprises an upper surface forming a distal recess, wherein the distal recess is generally planar and proximate the peripheral ridge, the distal recess having a boundary defined by the peripheral ridge, wherein the hinge of the wing facilitates the wing pivoting about another axis offset from the longitudinal axis, wherein the hinge is seated within the distal recess to allow the wing to pivot upwardly away from the distal recess.

2. The IV catheter system of claim 1 , wherein the catheter hub comprises further comprises a needle port at the catheter hub proximal end, wherein, in an insertion configuration, the needle is positioned within the cannula and the needle hub distal end is seated in the needle port of the catheter hub and wherein, in a fluid delivery configuration, the needle is positioned outside the catheter hub.

3. The IV catheter system of claim 1 , wherein the needle component includes a flash component having a proximal vent and at least one side vent.

4. The IV catheter system of claim 1 , wherein the catheter component includes a visual indicator.

5. The IV catheter system of claim 4 , wherein the visual indicator is covered by the needle hub distal end when a tip of the needle extends distally beyond the cannula and that is exposed when the tip of the needle is withdrawn into the cannula.

6. The IV catheter system of claim 1 , wherein the wing comprises a flexible material to facilitate the wing pivoting about the another axis offset from the longitudinal axis.

7. The IV catheter system of claim 1 , wherein the catheter component and the needle component each include a protrusion, wherein the protrusion of the catheter component and the protrusion of the needle component are configured to interface with each other to limit rotation of the needle component relative to the catheter component.

8. The IV catheter system of claim 7 , wherein the protrusion of the catheter component and the protrusion of the needle component prevent the wing from rotating downward below a securement platform of the catheter component.

9. The IV catheter system of claim 1 , wherein the peripheral ridge is positioned at a lateral portion of the outer edge of the grip, wherein the generally planar surface extends to a distal portion of the outer edge of the grip to facilitate the wing sliding past the grip.
