integrated peripheral intravenous catheter with improved probe access in the extension tube orifice

摘要

a vascular access device can be an integrated catheter. the vascular access device includes a catheter (103) and the catheter adapter (101) having a catheter dent (102) and side hole 9105). the contact angle of a probe is greater than 90 degrees. the angle of entry of a probe entering the catheter dent from the side hole may be less than 45 degrees. the vascular access device may include a component configured to direct the path of a probe towards the opening of the catheter. the component may be a protrusion extending to the lumen of the lateral orifice, the internal fluid passage path, and / or an extension tube, or a septum within the catheter dentum. the vascular access device includes an access adapter in fluid communication with the lateral orifice and allowing the insertion of a probe in the catheter through the lateral orifice with or without a separate luer adapter. there is an additional description of the methods of using a vascular access device.
