Embodiment Construction

[0022] figure 2 An example of a vascular access device 200 configured in accordance with one or more embodiments of the invention is shown. The access device 200 includes: a catheter adapter 201 from which a catheter 201a extends distally; a needle hub 202 from which a needle 202a extends distally; an extension tube 203 having a distal end 203a coupled to the catheter adapter 201 and proximal end 203b coupled to adapter 204; and, clamp 205 for restricting fluid flow through extension tube 203. Adapter 204 may generally be a Luer adapter configured to allow other access devices to be coupled to access device 200 .

[0023] Catheter adapter 201 may include a stable platform formed by sides 201b and 201c extending outwardly from opposite sides of catheter adapter 201 . Such as figure 2 As shown, in certain embodiments, access device 200 is configured for right-handed use, as extension tube 203 is coupled to the left side of catheter adapter 201 such that stabilization platform...

Abstract

An integrated vascular access device can include strain relief features to minimize the likelihood of the extension tubing becoming kinked during use. These strain relief features can be configured at both ends of the extension tubing to minimize the likelihood of kinking at the interfaces to the catheter adapter and a luer adapter. To provide strain relief at the catheter adapter end of the extension tubing, an interface formed of a flexible material can be aligned with an extension of the catheter adapter into which the extension tubing inserts. The interface can be integrated into a stabilization platform or formed separately from a stabilization platform. To provide strain relief at the luer adapter end of the extension tubing, a flexible spacer can be coupled to a distal end of the adapter and have a distal portion that is positioned around the extension tube.
