Description

[0001] Background of the Invention

[0002] Field of the Invention

[0003] This disclosure relates to an auxiliary fixation device for vascular access devices.

[0004] Description of related technologies

[0005] Vascular access devices (VADs) are inserted into a patient's peripheral vascular system. VADs can be left in place for short (days), medium (weeks), or long (months to years). VADs can be used for infusion therapy and / or blood draws. Common types of VADs include over-the-needle peripheral intravenous catheters (PIVCs) and central venous catheters (CVCs). Several solutions exist for securing VADs and maintaining the insertion site; however, clinicians often have limited options for managing the portion of the lumen extending outside the body. These loose extensions can create opportunities for the lumen to be pulled out, potentially affecting catheter position or the integrity of the insertion site. Adhesive tape and fabric dressings are sometimes used, but these can be cumbersome when accessing the catheter. Furthermore, when accessing the catheter, uncapped tubing poses a risk of contact contamination because clinicians often need to perform multiple steps. Summary of the Invention
