Background

The existing noninvasive ventilator oral-nasal mask oxygen supply mode comprises ventilator air supply end interface oxygen supply, ventilator connection mask interface oxygen supply and mask upper oxygen interface oxygen supply, and the discharge of gas in the mask mainly carries out air discharge through a safety valve connected with the mask or an air leakage hole existing in the mask.

The oxygen is mixed with the supplied gas in the breathing machine no matter which way the oxygen is connected and supplied, so that the dilution of the oxygen is caused, particularly, the higher the pressure of the breathing machine is, the higher the flow rate is, the more obvious the dilution of the oxygen is, so that the blood oxygen content of part of patients is lower after wearing the breathing machine than that of the patients without wearing the breathing machine, if the patients have serious carbon dioxide retention at the same time, the higher the pressure support of the breathing machine is required, and the lower the supply of the oxygen is, so that the treatment of diseases is not facilitated; when the safety valve is connected with the mask, the air leakage amount is not increased greatly along with the increase of the pressure of the respirator, so that the dilution to the oxygen is relatively less, but simultaneously, the carbon dioxide is difficult to discharge and the retention of the carbon dioxide is increased, and although the discharge of the carbon dioxide can be increased due to the increase of the pressure of the respirator, the mask with the air leakage hole has a remarkable dilution effect to the oxygen, and the oxygen supply capacity is insufficient.

Therefore, there is a need for a new breathing mask that addresses carbon dioxide retention while not diluting oxygen within the mask.
