Abstract

An IV catheter system may include a catheter component with a catheter hub, a cannula extending distally from the catheter hub, and a securement platform. The securement platform may include a wing, which may extend from the catheter hub. The IV catheter system may also include 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. The grip may be generally parallel to the axis and disposed on a side of the needle hub. The wing and the grip may be positioned to facilitate manipulation with a single hand to move the IV catheter system from an insertion configuration towards a fluid delivery configuration.

7. The IV catheter system of claim 5, wherein, in the insertion configuration, an entire bottom surface of the wing contacts the support surface of the grip.

8. The IV catheter system of claim 5, wherein, during motion of the IV catheter system from the insertion configuration toward the fluid delivery configuration, at least a portion of the bottom surface of the wing slides along the support surface of the grip.

9. The IV catheter system of claim 1, wherein the needle hub further comprises at least one gripping protrusion, wherein the gripping protrusion is disposed proximal to the grip.

10. An IV catheter system comprising an insertion configuration and a fluid delivery configuration, the IV catheter system comprising:

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

a needle extending distally from the needle hub distal end along an axis, wherein the wing is generally parallel to the axis; and

a grip extending from the needle hub beyond the catheter hub proximal end, wherein the grip is disposed generally parallel to the axis, wherein the grip comprises an upper surface and a support surface, wherein, in the insertion configuration, the needle is positioned within the cannula, the needle hub distal end is seated in the needle port, the upper surface of the grip is coplanar with an upper surface of the wing, and at least a portion of a bottom surface of the wing contacts the support surface, wherein, in the fluid delivery configuration, the needle is positioned outside the catheter hub

11. The IV catheter system of claim 10, further comprising a securement platform comprising a wing extending from the catheter hub,

wherein, in the insertion configuration, a distal end of the grip contacts a proximal end of the wing,

wherein the securement platform is positioned to receive first contact from a first digit of a hand of a user to urge the catheter hub distally and the grip is positioned to receive second contact from a second digit of the hand simultaneously with receipt of the first contact such that the first and second contacts cooperate to urge the IV catheter system to move from the insertion configuration toward the fluid delivery configuration.

12. The IV catheter system of claim 10, further comprising a securement platform comprising a wing extending from the catheter hub,

wherein the wing is a first wing, wherein the securement platform further comprises a second wing extending from the catheter hub, generally coplanar with the first wing such that, in the fluid delivery configuration, the first wing and the second wing rest on the skin,
