Abstract

Catheter assemblies are described having a catheter hub with a catheter tube and a needle hub with a needle projecting through the catheter tube. The catheter hub has a valve or a septum for stopping or slowing down the flow of fluid in or out of the catheter hub when the valve or septum is closed. The valve has features formed thereon to facilitate venting, opening, closing, or combinations thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application 61 / 799286, filed March 15, 2013, the contents of which are expressly incorporated herein by reference in their entirety for all purposes. technical field [0003] Current systems, devices and methods relate to infusion sets, particularly intravenous (IV) catheters. In particular, the systems, devices, and methods relate to flushable peripheral intravenous catheter assemblies having features that enable selective activation of fluid flow through the catheter assembly. Background technique [0004] Catheters are commonly used for various infusion treatments. For example, catheters are used to administer fluids, such as saline solutions, various medications, and parenteral nutrition, into a patient, to draw blood from a patient, or to monitor various parameters of a patient's vascular system. [0005] Catheters and / or needles are typically coupled to cath...
