Integrated peripheral intravenous catheter with improved access to extended tube port probes

摘要

The vascular access device can be an integrated catheter. The vascular access device includes a catheter (103) and a catheter adapter (101) having a catheter hub (102) and a side port (105). The contact angle of the probe exceeds 90 degrees. The entrance angle of the probe entering the catheter hub from the side port can be less than 45 degrees. The vascular access device may include components configured to direct the pathway of the probe to the catheter opening. The component can be a side port, an internal fluid passage, and / or a protrusion extending into the lumen of the extension tube, or a bulkhead in the catheter hub. The vascular access device includes an access adapter that fluidizes with the side port and allows insertion of the probe into the catheter through the side port with or without a separate luer adapter. Methods of using vascular access devices are further disclosed.
