Problems solved by technology

Although it is possible to inject fluid through the access port to flush blood from the extension tube, it is difficult to completely flush residual blood that may become lodged in the access port
Because the same access port is also often used to inject fluid into the patient's blood vessel, this residual blood may increase the risk of blood stream infection (BSI)

Embodiment Construction

[0026] Embodiments of the present disclosure will be described primarily in the context of integrated PIVCs. However, embodiments of the present disclosure extend to other integrated vascular access devices as well. For purposes of the specification and claims, an integrated vascular access device shall be construed as a vascular access device that includes an integrated extension kit.

[0027] figure 1 An example of a PIVC 100 constructed in accordance with some embodiments of the present disclosure is provided. PIVC 100 includes catheter adapter 110 from which catheter 111 extends distally, and needle assembly 120 from which needle 121 extends distally. Prior to insertion, needle assembly 120 is coupled to catheter adapter 110 such that needle 121 extends distally from catheter 111 . Catheter adapter 110 also includes a side inlet 112 that defines a fluid pathway into and out of conduit 111 . The exact configuration and function of catheter adapter 110 and needle assembl...

Abstract

A vascular access device may have a vented blood collection port. The vented blood collection port can be provided on a side port of the vascular access device that is positioned between a catheter adapter and an extension set. The side port provides separate fluid pathways for collecting blood and injecting fluids to thereby isolate the blood from the extension set. The vented blood collection port may be provided in the form of a septum housing that moves from a blood collection position to a fluid injection position. When in the blood collection position, the septum housing may enable the extension set to be primed and remain primed during a blood draw.

Description

technical field [0001] The present disclosure relates to vascular access devices having vented blood collection ports. Background technique [0002] Catheters are commonly used for various infusion therapies. For example, catheters can be used to inject fluids such as saline solution, various medications, and total parenteral nutrition into a patient. Catheters can also be used to draw blood from a patient. [0003] One conventional type of catheter is the trocar peripheral intravenous ("IV") catheter (PIVC). As the name implies, a trocar peripheral intravenous catheter is mounted over an introducer needle with a sharpened distal tip. The catheter and introducer needle can be assembled such that the distal end of the introducer needle extends beyond the distal end of the catheter with the bevel of the needle facing away from the patient's skin. The catheter and introducer needle are usually inserted through the skin at a shallow angle into the patient's blood vessel. ...
