Abstract
Abstract Solid, soft, penetrable, non-coring material for filling a side-arm injection port of an intravenous tube. The material occludes the injection port or other site where air or administered medications may be trapped in the tubing. The material fills the area that lies out of the main stream of the intravenous infusate while allowing medication injection through the non-coring material. The material also decreases or practically eliminates any weeping from the numerous injections into a port, lessening the chance for sepsis.
