Abstract

Claims (23)

1. An insertion device, comprising:

a housing, comprising:

a needle including a distal notch in a sidewall of the needle, the distal notch proximate a distal end of the needle, and a pair of proximal notches in the sidewall of the needle proximate a proximal end of the needle, wherein the distal notch and the pair of proximal notches are in fluid communication with a lumen of the needle;

a flash chamber enclosing the pair of proximal notches; and

a needle hub including a slot for receiving a proximal portion of the needle and the flash chamber; and

a catheter assembly, comprising:

a catheter including a catheter hub coupled to a proximal end of a catheter tube, the catheter hub including a valve and an annular ridge defined on an inner surface of the catheter hub proximal of the valve; and

a fluid control component disposed in the catheter hub, the fluid control component movable between a first position and a second position, the fluid control component including a plurality of longitudinal ribs spaced apart on an exterior surface of the fluid control component, each of the plurality of longitudinal ribs extending from a proximal end of the fluid control component to a distal end of the fluid control component, each of the plurality of longitudinal ribs comprising:

a notch at an intermediate portion between the proximal end and the distal end, the notch configured to engage the annular ridge in the first position; and

a protrusion at the proximal end configured to engage the annular ridge in the second position.

2. The insertion device according to claim 1 , wherein the valve of the catheter includes a tricuspid valve including three slits.

3. The insertion device according to claim 2 , wherein an outer termination point of each slit is a staggered termination point.

4. The insertion device according to claim 1 , wherein each of the plurality of longitudinal ribs includes a shoulder adjacent to the notch.

5. The insertion device according to claim 1 , wherein the fluid control component has a generally conical shape.

6. The insertion device according to claim 1 , wherein the plurality of longitudinal ribs comprise four equally spaced longitudinal ribs.

7. The insertion device according to claim 1 , wherein each of the plurality of longitudinal ribs extend proximal of a proximal opening of the fluid control component.

8. The insertion device according to claim 1 , wherein the fluid control component further comprises a fluid flow channel between each of the plurality of longitudinal ribs.

9. The insertion device according to claim 1 , wherein the flash chamber is formed from a translucent material.

10. The insertion device according to claim 1 , wherein the slot of the needle hub includes a plurality of shoulders configured to support the needle, wherein a proximal shoulder includes a proximal edge configured to prevent a flow of a liquid adhesive out of the slot when the liquid adhesive is used to secure the needle in the slot.

11. The insertion device according to claim 1 , wherein the needle hub includes a radially extending ridge disposed proximate a proximal end of the needle hub, the radially extending ridge configured to support a spring of the insertion device.

12. The insertion device according to claim 11 , further comprising a retraction system configured to selectively retract the needle into the housing, the retraction system comprising the spring and a retraction button in releasable engagement with the needle hub.

13. The insertion device according to claim 1 , further comprising a guidewire advancement assembly including a guidewire pre-disposed in the lumen of the needle.

14. The insertion device according to claim 13 , wherein the guidewire advancement assembly further includes a finger pad coupled to the guidewire, wherein the guidewire is designed for distal advancement upon distal advancement of the finger pad.
