[0002] At present, as a portable, lightweight hyperbaric oxygen therapy equipment, the soft oxygen cabin is widely used in medical rehabilitation, sports medicine and family health care fields. The soft oxygen cabin is usually composed of a flexible inflatable cabin body, a sealed door and window, an air inlet and exhaust system and a control device. Oxygen is delivered into the cabin through an oxygen generator or an oxygen cylinder to achieve hyperbaric oxygen therapy for patients or users. Compared with the traditional hard hyperbaric oxygen cabin, the soft oxygen cabin has the advantages of small size, light weight, foldable storage and convenient movement, and thus is gradually applied in clinical and home rehabilitation.

[0003] The existing soft oxygen cabin internal gas pipe should usually be fixed and installed (i.e. the gas pipe is arranged in the threading pipe, and the threading pipe is fixed in the cabin by welding). In actual use, the gas pipe should be arranged along the cabin wall or the cabin top to avoid hindering personnel activities or affecting the use of cabin equipment, and to ensure the stability of the pipe and its resistance to external interference. It can be seen that the threading pipe mainly plays a role in binding and protecting the gas pipe. However, since the soft oxygen cabin needs to be folded for storage, the threading pipe is in a curved state at this time. The traditional threading pipe has not been optimized in structure, and the curved concave side is in a squeezed state for a long time, which is prone to bending. Even the gas pipe inside the threading pipe is also prone to crushing due to bending, which affects oxygen delivery and poses a great safety hazard.
