Abstract
A fluid administration set with an infusion pump tube having indentations near its ends within its inner cylindrical wall. The indentations are preferably V-shaped annular grooves. Each groove engages an annular barb on a hollow fitting. The hollow fittings have base members for engaging retaining walls in the pump set apart from one another at a precise predetermined distance. The outer circumference of the infusion pump tube is enlarged in the area of the indentation. Tabs are provided on the hollow fitting assembly for securing the administration set against the infusion pump. The set may include a pressure dome for occlusion sensing on one of the hollow fitting assemblies.
