This creation is that related what is a kind of " Improvement type oxygen nasal tube ", this kind of oxygenNasal tube, it include an oxygen conveying pipe and a carbon dioxide delivery pipe, the oxygen conveying pipe and carbon dioxide delivery pipe partial structure system connection are integral, and the bottleneck throat of what sufferer is put by oxygen nasal tube one end system, and oxygen is enable to be directly entered respiratory apparatus by nasal cavity. It is not easy to lose that this case can be such that amount of oxygen concentrates, and can also detect the concentration of carbon dioxide simultaneously, and different is ideal practical.本創作係有關於一種「改良式氧氣鼻管」，該種氧氣鼻管，包括有一氧氣輸送管與一二氧化碳輸送管，該氧氣輸送管與該二氧化碳輸送管部份結構係連結成一體，且該氧氣鼻管一端係置放於病患之咽喉部，使氧氣得以由鼻腔直接進入呼吸器官。本案能使氧氣量集中不易散失，也能同時偵測二氧化碳之濃度，殊為理想實用。
