초록 ▼

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.

[ What is claimed is:] [1.] A swivel connector consisting of:a) a body structure extending along a longitudinal axis from a first end to a second end and having a hole extending longitudinally through said body structure and between said first and second ends and being oriented centrally about said longitudinal axis, said body structure having an outer body structure extending longitudinally along and radially from said longitudinal axis at a first radial distance and said body structure includes a first body member piece having a bore and a second body member piece having a larger tapered bore, said first body member piece terminating at one end in a tube structure which is received within said second body member piece and extends beyond the end of said second body member piece, said extension having a slightly larger diameter than the smallest diameter of the bore of the second body member piece which receives the tube structure, and means for joining said tube structure and extension so that said tube structure and extension are permanently received in rotational relationship with said second body member piece and sealing means located between the tube of the first body member piece and the bore of the second body member piece to prevent gases from leaking through the bore of the second body member piece, said sealing means including a shoulder formed by a larger diameter untapered portion of the tube located in a complimentary diameter bore of said second body member piece, said bore diameter extending sufficiently toward the tip of said structure to receive an O-ring seal, and said body members on said body structure including a pair of conical end portions and a central body portion which includes a plurality of V-shaped ridges extending longitudinally along and projecting radially outwardly from the central body portion relative to said longitudinal axis and wherein the space between said conical end portion and said central body portion contains a plurality of collars having annular-shaped channels there between.
