Fluid delivery device and method for assembling and disassembling fluid delivery device

The invention relates to a fluid delivery device and a method for assembling and disassembling a fluid delivery device. A fluid transport device (1) comprises: a first line connector (10); a second line connector (20); and an inner line assembly (30) fluidly connecting the first line connector (10) to the second line connector (20) via the corresponding first and second coupling ends (31, 32). In the installed state (50), an outer line assembly (40) of the device (1) is attached to the first line connector (10) and to the second line connector (20) such that the outer line assembly (40) covers the first and second coupling ends (31, 32). In a disengaged state (60), the outer line assembly (40) is disengaged from the first and second line connectors (10, 20), where the outer line assembly (40) is movable relative to the inner line assembly (30) to expose the first coupling end (31) or the second coupling end (32). 本发明涉及流体输送装置以及用于组装和拆卸流体输送装置的方法。流体输送装置(1)包括：第一管线连接器(10)；第二管线连接器(20)；以及内管线组件(30)，所述内管线组件经由对应的第一和第二联接
