For example, if a large-bore IV is inserted for the purpose of massive resuscitation, and the available NFC was of a smaller gauge than the IV and tubing, then the clinician will likely discard it from the connector.Ī common NFC is the BD Q-Syte (BD, Franklin Lakes, NJ). In our opinion, the parameter with the greatest influence on the average clinician's decision regarding whether to use the NFC is the gauge diameter of the connector in the context of the clinical need for the IV. A given healthcare facility is likely to stock one pediatric model and a separate adult model. Usually, the NFC is already attached to the short tubing extension. ![]() Typically, clinical practices purchase a single type of NFC model for routine use. 7 Implementing these features minimizes biofilm development in the internal luminal surface of the device and decreases the risk of red blood cell hemolysis, in turn minimizing the risk of CRBSI, fibrin clot formation, and occlusion. These include a direct fluid pathway with minimal tortuosity, Luer access with minimal or no blood reflux, closed-system feature, and lack of a clamping sequence. Over the years, several engineering features have been favored when designing needle-free connectors (NFCs). 2– 5 These needleless designs have gained favor in clinical practice since they reduce needle stick injuries and decrease the rate of CRBSI. 1 Because of their 64% to 70% lower catheter-related blood stream infection (CRBSI) rates, in 2011, the Centers for Disease Control and Prevention released a Category II recommendation favoring split septum valve devices over mechanical valve devices. Split septum designs, on the other hand, lack these internal moving parts. This is commonly achieved through an elastic spring-like mechanism that keeps the centerpiece in the closed position when disconnected. When the Luer end pushes the centerpiece downward, internal components move to allow the flow of fluid within the device. In contrast, mechanical valve devices consist of centerpieces that open on the external connection surface. Conversely, when the tubing is disconnected, the diaphragm acts as a physical barrier to flow and to the entry of bacteria. When the blunt cannula of the tubing is connected, it pierces the diaphragm open, allowing fluid to flow. This is achieved through a simple design of a prepierced rubber diaphragm. These tubing caps contain a needleless, valveless system that allows fluid to flow directly through the lumen of the catheter while also preventing backflow of fluid or blood when the tubing extension is not connected. The split septum cap then can be conveniently connected to the longer IV tubing, which is connected to the infusion and exchanged as needed. ![]() Typically, the angiocatheter is inserted into a vein and connected to a short tubing extension that is capped by split septum ends. Split septum medical devices are used in tubing for intravenous (IV) fluid administration-an extremely common clinical task. ![]()
