Description

Technical Field

[0001] The utility model belongs to the technical field of ECMO pipeline fixing devices, and particularly relates to a head-mounted inflatable ECMO neck pipeline fixator. Background Art

[0002] The ECMO (extracorporeal membrane oxygenation) system is an extracorporeal life support system that replaces the cardiopulmonary function of patients through extracorporeal circulation equipment. It is mainly used to treat critically ill patients such as acute respiratory distress syndrome, severe pneumonia, and heart failure. The core components of the ECMO system include: a blood pump, an oxygenator, and a pipeline system.

[0003] The ECMO pipeline is a key component in the ECMO system. When the blood circulation and gas exchange functions of patients are severely impaired, it provides supportive treatment. Deoxygenated blood is drawn out through a venous catheter, and oxygenated blood is transfused back into the patient's body through an arterial catheter. The oxygenator performs gas exchange through a membrane, removing carbon dioxide from the blood and adding oxygen, and the blood pump maintains blood circulation to ensure the continuous flow of blood in the extracorporeal circuit.

[0004] In current clinical practice, in some cases, the ECMO pipeline only relies on the insertion depth of the catheter and gravity to maintain its position. This method has significant risks because the pipeline is prone to movement, resulting in tube disconnection or improper position, thus affecting the treatment effect. Therefore, vascular forceps are clinically used to fix the ECMO pipeline on the bedsheet to prevent it from moving. However, this fixing method is not firm enough. Especially when the patient moves or the bedsheet is adjusted, the pipeline may still slide or dislocate, presenting obvious dangers. Especially during long-term treatment, the patient's activities, turning over, and changing of the bedsheet may all cause the pipeline to become unstable, thereby affecting the safety and treatment effect of the patient. Therefore, a head-mounted inflatable ECMO neck pipeline fixator is proposed. Content of the Utility Model
