Abstract

An attachment for a catheter assembly may include a platform, which may include an upper surface and a bottom surface. The bottom surface may be configured to contact skin of a patient. At least a portion of the upper surface may be configured to support the catheter assembly. The upper surface may support the catheter assembly at an angle with respect to skin of the patient that is approximately equal to an insertion angle of a catheter of the catheter assembly. The attachment may include snap feature coupled to the upper surface of the platform. The attachment may include a blunt cannula extending distally from the snap feature. The blunt cannula and the portion of the upper surface may provide a generally straight pathway for an instrument inserted distally through the attachment into the catheter assembly.

First claim

The invention claimed is:

1. An attachment for a catheter assembly, the attachment comprising:
a wedge-shaped platform having an upper surface and a bottom surface, wherein the bottom surface is configured to contact skin of a patient, wherein the upper surface comprises a groove configured to be disposed underneath the catheter assembly and support the catheter assembly;
a snap feature coupled to the upper surface of the wedge-shaped platform, wherein the snap feature comprises an arm; and
a blunt cannula fixed with respect to the wedge-shaped platform and configured to be inserted into a proximal end of a catheter adapter of the catheter assembly, the blunt cannula extending distally from the snap feature beyond a distal end of the arm, wherein the groove is angled downwardly with respect to the skin of the patient and is configured to maintain a downward insertion angle for the catheter assembly with respect to the skin of the patient.

2. The attachment of claim 1 , wherein the blunt cannula is generally parallel to a portion of the upper surface.

3. The attachment of claim 2 , wherein the portion of the upper surface is disposed at an angle with respect to the bottom surface.

4. The attachment of claim 3 , wherein the angle is 30° or less than 30°.

5. The attachment of claim 4 , wherein the portion of the upper surface comprises an outer portion that is generally planar and configured to support a wing of the catheter assembly.

6. The attachment of claim 1 , further comprising a push tab coupled to the upper surface.

7. The attachment of claim 1 , wherein the arm comprises a prong.

8. The attachment of claim 1 , wherein the arm is a first arm, wherein the snap feature further comprises a second arm and a third arm, wherein the first arm and the second arm are attached to the upper surface, wherein the third arm comprises a prong.

9. The attachment of claim 1 , further comprising:
a bond pocket coupled to the snap feature;
an extension tube having a proximal end and a distal end, wherein the distal end is secured within the bond pocket; and
a connector coupled to the proximal end of the extension tube.

10. The attachment of claim 1 , wherein the bottom surface comprises an arch extending generally perpendicular to the blunt cannula.

11. The attachment of claim 1 , wherein the wedge-shaped platform comprises an aperture disposed beneath the blunt cannula.

12. The attachment of claim 1 , wherein the wedge-shaped platform is generally U-shaped and does not extend beneath the blunt cannula.

13. The attachment of claim 1 , further comprising a connector proximate the snap feature.

14. The attachment of claim 13 , wherein the connector comprises a plurality of ribs.

15. The attachment of claim 13 , wherein the connector comprises wings.

16. The attachment of claim 13 , further comprising an insert cap or a luer cap coupled to the connector.

17. The attachment of claim 1 , further comprising an obturator extending through the blunt cannula.

18. The attachment of claim 17 , wherein the obturator has a sharp tip.

19. The attachment of claim 17 , wherein the obturator has a blunt tip.
