Embodiment Construction

[0043] The double lumen tubing according to the invention is designed for use as a catheter and can be used with any catheter device in which a double lumen catheter is required.

[0044] exist figure 1 The reference number 10 in the figure shows a first preferred embodiment according to the invention. Dual lumen tubing 10 includes a tubular wall 12 having an outer surface 14 and an inner surface 16 . Duct 10 also includes an interior or partition wall 18 that divides the lumen of duct 10 into two lumens: a first lumen 20 and a second lumen 22 . Thus, each of lumens 20 and 22 is defined by inner surface 16 of tubular wall 12 and inner (separator) wall 18 .

[0045] The cross-sectional area of ​​each of the cavities 20, 22 includes an arcuate portion 24, 24' and a substantially planar portion 26, 26' opposite the corresponding arcuate portion 24, 24', the planar portion 26, 26' being defined by the inner wall 18. Surfaces 27 , 27 ′ are defined, and arcs 24 , 24 ′ are defined...

Abstract

Double lumen tubing (10) having a substantially circular cross-section and comprising a tubular wall (12) each extending about a longitudinal central axis of the tubing (12), and having a wall thickness being defined between the outer surface (14) and the inner surface (16). The tubing (10) comprises an inner wall (18) inside the tubing (10) for dividing it into a first (20) and a second (22) lumen, the inner wall (18), and each lumen (20; 22) comprising a cross section with an arcuated portion (24; 24' ) and a substantially plane portion (26; 26' ) opposite to the arcuated portion (24; 24'), the plane portions (26; 26') of the lumens (20; 22) lying adjacent to one another. Further, a centre region (30) of the arcuated portion (24; 24') of the cross section of at least one of the first (20) or second (22) lumen, and the regions (39) where the tubular wall (12) meets the inner wall (18), have a wall thickness that is smaller than the wall thickness of two tubular wall regions (32; 34) located left and right of said centre region (30).

Description

technical field [0001] The present invention relates to a dual lumen conduit having a generally circular cross-section and comprising a tubular wall having an outer surface and an inner surface, each of which extends around a longitudinal central axis of the conduit. The duct has a wall thickness defined between an outer surface and an inner surface, and the duct also includes an inner wall within the duct for dividing the duct into a first lumen and a second lumen, each lumen defined by the inner surface of the tubular wall and an inner wall, and each cavity includes a cross-section having an arcuate portion and a generally planar portion opposite the arcuate portion, the planar portions of the cavity being adjacent to each other. Background technique [0002] Dual lumen tubing of this type is generally known in the art. [0003] Such double lumen tubing is used eg in medical devices for accessing the vasculature of a patient eg during infusion and / or removal of bodily flu...
