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 first end and a proximal end, the first end of the catheter adapter supporting a catheter;

a needle tip shield having a first end and a proximal end, the first end of the needle tip being removably coupled to the proximal end of the catheter adapter; and

a needle hub having a first end, a proximal end, and a middle portion, the first end of the needle hub being removably coupled to the proximal end of the needle tip shield, the middle portion including a gripping surface for accommodating opposing digits to enable a straight grip of the catheter device, the proximal end of the needle hub further including an end surface for accommodating a thumb, the proximal end of the needle hub including a needle fixedly attached thereto and extending outwardly therefrom such that the needle intersects, aligns, and coordinates the needle tip shield, the catheter adapter and the catheter to provide an integrated catheter device, the gripping surface further comprising a distal end peak and a proximal end, the distal end peak of the gripping surface being positioned at a first radial distance from the needle, and the proximal end of the gripping surface being positioned at a second radial distance from the needle, the first radial distance being greater than the second radial distance, wherein the distal end peak of the gripping surface further comprises a guard feature interposed between the gripping surface and the needle tip shield.

2. The catheter device of claim 1, wherein the first end of the needle hub further comprises a paddle grip extending outwardly therefrom, the paddle grip having a top surface and a bottom surface, the top surface configured to accommodate a thumb, and the bottom surface configured to accommodate an opposing digit whereby the paddle grip is pinched between the thumb and the opposing digit to enable a winged grip of the catheter apparatus.

3. The catheter device of claim 2, further comprising a securement platform extending laterally outward from the catheter adapter, the securement platform having a leading edge configured to accommodate a first digit, the paddle grip having a leading edge configured to accommodate a second digit, and the end surface being configured to accommodate the thumb to enable a ported grip of the catheter device, and wherein a top surface and a bottom surface of the securement platform is further configured to accommodate opposing digits to enable a winged grip of the catheter device.

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

5. The catheter device of claim 1, further comprising a catheter adapter catch occupying a portion of the proximal end of the catheter adapter, wherein the catheter adapter catch is secured within the first end of the needle tip shield thereby interlocking the needle tip shield and the catheter adapter prior to removal of the needle from the catheter adapter.

6. The catheter device of claim 1, wherein the guard feature provides a barrier between the opposing digits and needle tip shield.

7. The catheter device of claim 1, further comprising a concave surface interposed between the guard feature and the gripping surface.

8. The catheter device of claim 7, wherein a portion of the concave surface is the gripping surface.

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

10. The catheter device of claim 1, further comprising:

a securement platform occupying a first side of the catheter adapter, the securement platform having a planar surface in a first plane that is generally perpendicular to the gripping surface of the needle hub middle portion; and

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

11. The catheter device of claim 10, wherein a first portion of the guard feature is interposed between the gripping surface and the securement platform, and a second portion of the guard feature is interposed between the gripping surface and the paddle grip.

12. The catheter device of claim 10, 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 end surface are contacted with the first digit, the second digit and the thumb, respectively, to enable a ported grip of the catheter device.
