In the present application, the nasal cannula 20 directly inputs oxygen into the nasal cavity of the patient, which means that the end of the nasal cannula 20 is inserted into the nostril to input oxygen to the patient. The mask conduit 30 is used for inputting oxygen into the mask 10, at least a part of the oxygen delivered by the mask conduit 30 is directly introduced into the mask 10 instead of directly into the patient's nostrils, and in a specific case, the part of the oxygen delivered by the mask conduit 30 is directly introduced into the mask 10 and the part of the oxygen is directly inputted into the patient's nostrils through the nasal cannula 20.
The application adopts a combined oxygen supply method, and compared with the oxygen supply by using the nasal catheter 20 or the oxygen supply by using the face mask 10, the oxygen supply method can improve the concentration of inhaled oxygen without changing tidal volume and ventilation per minute, thereby improving hypoxemia.
The principle is as follows: as shown in fig. 3, the area a is the area of the single-sided nasal cavity opening, and the area b is the area of the single-sided nasal catheter opening. When the tidal volume and the nasal catheter ventilation volume are constant, the combined oxygen supply method increases the inhaled oxygen concentration in the (a-b) area during inhalation compared with the oxygen supply by using the nasal catheter alone; the combined oxygen delivery method increases the inhaled oxygen concentration in region b during inhalation as compared to oxygen delivery using a mask alone. Thus, the combined oxygen therapy can improve hypoxemia by increasing the inspired oxygen concentration without changing tidal volume, minute ventilation and nasal catheter ventilation.
The combination oxygen mask improves the patient's inhaled oxygen concentration and has a greater ability to correct hypoxemia than either nasal cannula oxygen alone or mask oxygen alone, thereby avoiding the use of mechanical ventilation in some patients. Mechanical ventilation is avoided, so that treatment cost is reduced, pain of a patient and complications related to mechanical ventilation are reduced, and prognosis of the patient is possibly improved. The combined oxygen supply mask has low cost, simple and convenient operation and easy clinical popularization.

The structure is more compact, and the patient can wear the clothes more easily.
And, the face mask 10 is preferably provided with an air outlet, on which a breather valve is provided.
The utility model provides a pair of joint oxygen mask adopts the joint method of giving oxygen, for exclusive use nasal catheter oxygen therapy or face guard oxygen therapy, thereby can improve and inhale oxygen concentration and improve hypoxemia under the condition that does not change tidal volume and minute ventilation volume.
And more preferably, as shown in fig. 4, a slidable baffle 41 is arranged inside the three-way joint 40 for adjusting the sizes of the two oxygen outlets, for example, by shifting the baffle 41 to the left, the oxygen outlet communicating with the nasal cannula 20 becomes relatively narrow, so as to adjust the amount of oxygen directly entering into the nasal cavity, and synchronously adjust the amount of oxygen directly entering into the mask 10; otherwise, the baffle plate 41 is shifted to the right, the oxygen amount directly introduced into the nasal cavity is increased, and the oxygen amount directly introduced into the mask 10 is synchronously decreased; thereby being suitable for the oxygen therapy requirements of different patients and being flexible and convenient.
The three-way connector 40 is provided with a chute communicated with the inside and the outside, the shifting rod extends into the three-way connector from the outside through the chute and is fixedly connected with the baffle 41, and the shifting rod is forcibly shifted to move along the chute, so that the baffle 41 can be driven to slide left and right in the three-way connector.
