Abstract
Abstract Apparatus for inserting tubes of varying sizes, such as catheter tubes, into a patient including mating upper and lower needle portions, the lower portion being flattened on the bottom surface for abutment with the body of the patient with tabs extending outwardly on both sides of the mating portions also adapted to abut against the body of the patient. The two mating portions are removably secured together so that the mating needle halves form an elongated cylindrical needle extending outwardly form one side of the secured portions and the mating portions forming a slot on the other side for receiving the luer adapter of a stylet therein.
