Abstract
A tube coupling system serves for providing annular flow through a flexible annular double lumen tube between fluid reservoir(s) and flexible connection pieces of an annular double lumen device. The tube coupling system has a first coupling component and a second coupling component and an end fitting system. The first coupling component that has a female coupling part and a male coupling part adapted for coupling to a proximal end of the flexible annular double lumen tube. The second coupling component has a second interior pipe that axially extends inside a second exterior pipe, a first end fitting adapted for coupling to at least the female coupling part of the first coupling component, and a second end fitting adapted for coupling to any of the flexible annular double lumen tube or the flexible connection pieces of an annular double lumen device.
