[0002] Extracorporeal membrane oxygenation (ECMO) is an important life support technology used to provide temporary oxygenation and circulation support in cases of heart and lung failure. During ECMO treatment, patients often need to be transported within the hospital, such as from the emergency rescue room to the intervention room, to the operating room to the EICU, to the ICU, or to other departments for CT examination. It can also be from the scene of an emergency outside the hospital to the hospital, or between other medical units. During the transportation process, the fixing device of the pipeline is crucial to ensuring patient safety and maintaining treatment continuity.
[0003] An ECMO system includes multiple extracorporeal pipelines (such as arterial pipelines, venous pipelines, monitoring pipelines, etc.), which are thick, heavy, and directly connected to the patient's blood vessels. Currently, during transportation, the fixing of ECMO pipelines has the following problems and defects:
[0004] 1. Primitive fixing method: Currently, adhesive tape, bandages, or ropes are commonly used to simply bundle the pipelines on the bed rail or stretcher. This method is not secure and can easily cause the pipelines to shift, pull, or twist during transportation.
[0005] 2. High risk: Accidental pulling of the pipelines can cause endothelial damage, puncture site bleeding, and even the most dangerous - pipeline slippage, leading to massive bleeding and air embolism in the patient, which can be life-threatening.
[0006] 3. Lack of buffer protection: Rigid fixation cannot effectively buffer the vibrations and shaking during transportation, and the stress is directly transmitted to the patient's puncture site.
