A moist heat exchange oxygen mask, as shown in Figures 1 and 2, includes a mask body 1 for covering a patient's face. The mask body 1 is provided with an oxygen inlet for the patient to inhale oxygen. The mask body 1 is provided with a moist heat exchange device 2 at the position of the oxygen inlet. One end of the moist heat exchange device 2 is connected to the mask body 1 , and the other end of the moist heat exchange device 2 is connected to the oxygen connection pipe 3 .

During the oxygen inhalation process of the patient, the moisture heat exchange device 2 can exchange the moisture and heat of the gas inhaled by the patient, keep the mouth moist, prevent the patient from breathing with the mouth open, the airway is dry and the sputum is thick, so that the sputum can be easily sucked out.

Preferably, the moist heat exchange device 2 includes a casing. The two ends of the shell are respectively provided with an air inlet and an air outlet, the air outlet is communicated with the oxygen inlet of the mask body 1 , and the air inlet is communicated with the oxygen connecting pipe 3 . A damp heat filter screen is arranged inside the shell, and the material of the damp heat filter screen is polyurethane.

When in use, the moist heat filter absorbs moisture and heat exhaled by the patient. When the inhaled oxygen passes through the moist heat filter, it brings water and heat back into the airway, which can keep the patient's mouth moist. The moist heat filter has a filtering function, which increases the cleanliness of inhaled oxygen and reduces the invasion of external bacteria to reduce the occurrence of lung infections. With moderate humidification, effective heating and filtration functions, oxygen inhalation is closer to the physiological state. Since the temperature and humidity of inhaled oxygen are close to physiological needs, the amount of sputum secretion is reduced, and the complications such as insufficient humidification, excessive humidification, and respiratory tract irritation are reduced, which reduces the workload of nursing.
