Abstract

Keep vein open (KVO) infusion flow control devices are provided. The KVO infusion flow control device couples to intravenous (IV) tubing and includes a flow controller that provides a full open fluid flow rate through an outlet portion of the IV tubing when the flow controller is in an open position, and a KVO fluid flow rate through the outlet portion of the IV tubing when the flow controller is in a KVO position. Visual indicators are disposed on the KVO infusion flow control device.

Description

technical field [0001] The present invention relates to an infusion flow control device. Background technique [0002] During use of an intravenous (IV) infusion set, blockages in IV lines are a common but undesirable occurrence in a patient's IV access due to the coagulation function of fibrin. Catheter occlusion may be due to thrombosis, drug or parenteral nutrition deposits, or mechanical factors. Blockage due to this effect also provides potential nesting material for microorganisms, thereby also increasing the risk of catheter-associated bloodstream infections. Typical solutions to catheter blockages are flush and lock methods such as tissue plasminogen activator (tPA), heparin fixation, and catheter replacement. However, these typical flush and lock methods have a significant impact on clinician time and hospital costs. [0003] It would be desirable to provide maintain venous patency (KVO), also known as maintain patency (TKO), infusion flow control devices with sa...
