Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to an improved high-flow nasal oxygen tube. Background Art

[0002] The design of the high-flow nasal oxygen tube currently used in clinical practice is that after the patient wears the nasal congestion, the oxygen hose is extended from the right side of the patient to connect the ventilator or a dedicated high-flow oxygen therapy machine, which brings some inconvenience to clinical treatment and nursing. First, in clinical practice, especially in the intensive care unit, the patient's ventilator is often placed on the left side of the patient. After conventional wearing, the oxygen hose will circle around the head and cause discomfort to the patient. Second, the patient's right neck position often has a deep vein catheter and is connected to many intravenous injection pumps. Conventional wearing may affect the use of the patient's right venous pump. Third, some critically ill patients need to have a nasogastric tube or a nasojejunal tube due to their condition, or even both at the same time. The commonly used high-flow nasal oxygen tube affects the nasal congestion opening due to the retention of the nasogastric tube / nasojejunal tube, causing the treatment effect of high-flow oxygen therapy to be affected. Fourth, the conventional high-flow nasal oxygen tube is designed with a circular adjustment belt, which is not easy to fix when the patient wears it, and it is easy to shift and fall off, causing the treatment effect of high-flow oxygen therapy to be affected. Fifth, the conventional high-flow nasal oxygen tube nasal congestion design is prone to twisting of the nasal congestion tube due to sagittal plane rotation, resulting in poor oxygen supply.
