Abstract: An apparatus for holding a catheter of a type having a flexible tube which can have one end thereof which extends into a large vein near a heart. The tube has a closure cap on the other end thereof for allowing the introduction of medications or fluids into the blood in the tube so that they can be quickly mixed with blood and thereby transported to other parts of the body for permitting blood to be quickly withdrawn therefrom. An elongated, flexible, elastic member is adapted to extend completely around the chest of a person and over the flexible tube at the location where the tube exits the body. Hook and loop closure members are provided on the flexible members for holding the tube in a coiled position adjacent the flexible member.
