Abstract

A universal gripping surface is provided on an intravenous catheter assembly. The universal gripping surface provides a plurality of surfaces whereby a user may grip the catheter assembly in a desired gripping configuration for improved balance and control of the catheter assembly during insertion of the catheter. Additionally, the universal gripping surface includes a guard feature to prevent a user'"'"'s unintended contact with various components of the catheter assembly whereby the contact may result in an undesirable “over the bevel” condition.

Claims

1. An intravenous catheter device, comprising:

a catheter adapter having a proximal portion located opposite a catheter;

a needle hub having a distal end and a proximal end, the distal end being removably coupled to the proximal portion of the catheter adapter, the needle hub including a fixedly attached needle extending outwardly therefrom;

a first gripping surface disposed on a first side of the needle hub;

a second gripping surface disposed on a second side of the needle hub opposite the first side;

a first guard feature protruding outwardly from a distal end of first gripping surface, the first guard feature being shaped and sized to providing a physical barrier between a first digit on the first gripping surface and the catheter adapter;

a second guard feature protruding outwardly from a distal end of second gripping surface, the second guard feature being shaped and sized to providing a physical barrier between a second digit on the second gripping surface and the catheter adapter;

a securement platform extending laterally outward from a first side of the catheter adapter to provide a leading edge, the securement platform having a planar surface in a first plane, wherein the first plane is generally perpendicular to the gripping surface of the needle hub; and

a paddle grip extending outwardly from a portion of the distal end of the needle hub, the paddle grip being positioned adjacent to the catheter adapter and opposite the securement platform, the paddle grip having a leading edge and further having a planar surface in a second plane that is generally parallel to the first plane.

2. The catheter device of claim 1, wherein the leading edge of the securement platform and the leading edge of the paddle grip are oppositely positioned and approximately parallel, the leading edge of the securement platform being capable of accommodating a first digit, the leading edge of the paddle grip being is capable of accommodating a second digit, and the proximal end of the needle hub being capable of accommodating a thumb to enable a ported grip of the catheter device, and wherein a portion of the securement platform is configured to accommodate opposing digits to enable a winged grip of the catheter device.

3. The catheter device of claim 2, wherein the first guard feature is interposed between the first gripping surface and the securement platform.

4. The catheter device of claim 3, wherein each of the first gripping surface and the second gripping surface comprises a contoured feature capable of accommodating ergonomic features of the opposing digits.

5. The catheter device of claim 1, wherein the paddle grip comprises a top surface and a bottom surface, the top surface capable of accommodating a thumb, and the bottom surface capable of accommodating an opposing digit whereby the paddle grip is pinched between the thumb and the opposing digit to enable a winged grip of the catheter device.

6. The catheter device of claim 5, wherein the second guard feature is interposed between the second gripping surface and the paddle grip.

7. The catheter device of claim 5, further comprising a first leading edge forming a distal portion of the paddle grip, wherein the first leading edge is configured to accommodate a second digit.

8. The catheter device of claim 7, further comprising a securement platform fixedly attached to the catheter adapter, and positioned generally opposite the paddle grip, wherein the securement platform comprises a second leading edge approximately parallel to the first leading edge of the paddle grip and configured to accommodate a first digit, wherein the second leading edge, the first leading edge, and the proximal end are contacted with the first digit, the second digit, and the thumb, respectively, to enable a ported grip of the catheter device.

9. The catheter device of claim 1, wherein a portion of the guard feature comprises a portion of the gripping surface.

10. The catheter device of claim 1, wherein the proximal portion of each of the first guard feature and the second guard feature each curve outwardly from the first gripping surface and the second gripping surface, respectively.

11. The catheter device of claim 1, wherein a distal edge of the securement platform comprises a first leading edge to support a first digit, and a distal edge of the paddle grip comprises a second leading edge to support a second digit, wherein the first leading edge, the second leading edge and the proximal end of the needle hub are contacted with the first digit, the second digit and the thumb, respectively, to enable a ported grip of the catheter device.

12. An intravenous catheter device, comprising:

a catheter adapter having a proximal portion located opposite a catheter;

a needle hub having a distal end and a proximal end, the distal end being removably coupled to the proximal portion of the catheter adapter; and

a paddle grip extending distally from the distal end of the needle hub and positioned adjacent to the catheter adapter, the paddle grip being shaped and sized to accommodate a first digit on a top surface of the paddle grip and a second digit on a bottom surface of the paddle grip, wherein the paddle grip is positioned opposite a securement platform of the catheter adapter,

a first gripping surface disposed on a first side of the needle hub;

a second gripping surface disposed on a second side of the needle hub opposite the first side;

a first guard feature protruding outwardly from a distal end of the first gripping surface, the first guard feature being shaped and sized to providing a physical barrier between a user'"'"'s digit on the first gripping surface and the catheter adapter; and

a second guard feature protruding outwardly from a distal end of the second gripping surface, the second guard feature being shaped and sized to providing a physical barrier between a user'"'"'s digit on the second gripping surface and the catheter adapter.
