Abstract
A tubing end-piece interconnects a free end of a piece of tubing and a tubing connector or fitting so that a fluid can flow between the tubing and the fitting or connector. The tubing end-piece includes a body member extending along a longitudinal axis with a bore extending longitudinally therethrough. The body member has an elongated body portion, a doughnut-shaped head portion and a frustoconically-shaped tail portion. The body portion has an outer body surface configured in a shape of a frustum that tapers from a first end and towards a second end. The doughnut-shaped head portion is connected to the first end of said body portion and extends radially outwardly relative to the longitudinal axis to form in cross-section an outer curved surface commencing from the first end and terminating in an outer peripheral edge which defines a first opening into the bore. A frustoconically-shaped tail portion is connected to the second end of the body portion and tapers from the second end and towards a second opening into the bore. The body member has an inner first surface and an inner second surface defining the bore and has a plurality of splines which are spaced apart from one another and extend longitudinally along and outwardly from the outer body surface. The present invention also includes a connector adapted to interconnect a pair of tubing end-pieces so that the fluid can flow between and through the respective pieces of tubing and the pair of tubing connectors, and present a connection which resists snagging when trailed from a portable or fixed source of oxygen gas to an ambulatory patient.
