A simple oxygen humid bottle, including a bottle body, a cover body, and a spray tube, the side of the bottle body has an air outlet pipe, the cover body is provided on the bottle body and has an air inlet pipe, and the cover body is provided on one side There is an adjustment hole. The adjustment hole is provided with a movable adjustment body for opening and closing the adjustment hole. The adjustment body has a toggle part. The upper end of the first branch pipe of the injection pipe communicates with the intake pipe. The spray hole at the lower end of the branch pipe corresponds to a flow guiding portion, the flow guiding portion extends toward the adjusting hole, and the lower end of the second branch pipe communicates with a duct. Oxygen from the oxygen supply unit is passed through the air intake pipe, the second branch pipe, and the catheter and is humidified by the water in the bottle and then discharged from the air outlet pipe for transmission to the patient. The adjustment body can be moved by the toggle to change the adjustment The size of the hole, the diversion part can easily guide the oxygen ejected from the first branch tube to exit the bottle body through the adjustment holes of different sizes, and then the oxygen concentration can be adjusted (that is, the fraction of oxygen, FiO2), which is convenient for selecting patients The required oxygen inhalation concentration value (eg 28% to 100%).一種簡便型氧氣潮濕瓶，包含一瓶體、一蓋體、一噴射管，瓶體一側具有一出氣管，蓋體設於該瓶體上且具有一進氣管，該蓋體一側設有一調整孔，該調整孔設一可活動狀之調整體，用以開啟、關閉該調整孔，該調整體具有一撥動部，噴射管之第一支管上端連通該進氣管，該第一支管下端噴孔對應一導流部，該導流部朝該調整孔延伸，該第二支管下端連通一導管。氧氣供應單元之氧氣經由進氣管、第二支管、導管並經瓶體內的水濕化後由出氣管排出以傳輸給病患使用，而可藉由撥動部使調整體移動，以改變調整孔之大小，導流部可輕易地導流第一支管噴出的氧氣經由不同大小的調整孔排出瓶體外，進而可調整氧氣濃度(即調整分率，fraction of oxygen, FiO2)，便於選擇病患所需的氧氣吸入濃度數值(如28%至100%)。
