Clinically, most noninvasive ventilators adopt single-circuit ventilation, and the ventilators do not have exhalation valves, so an external exhalation device is needed to realize patient exhalation. The expiratory valve is in a continuous open state, and the size of air leakage is related to the pressure in the pipeline and the type and caliber of the expiratory valve. The noninvasive ventilation and expiration devices commonly used in clinic at present comprise two types: one is an independent expiratory valve, which comprises a platform valve, a side hole valve and a mute valve; the second category is mask-integrated exhaling devices.

The side hole valve realizes the ventilation function of the breathing mask mainly by installing a valve plate with an air leakage hole on the mask, the structure is simple, and the air pressure of the lung is higher, the air output is higher; the air leakage principle of the mute valve is the same as that of the side hole valve box body, and the volume of air leakage is reduced due to the fact that the air leakage area of the mute valve is increased, but the air leakage amount is correspondingly increased; the structure of the platform valve is more complex than the two valves, and mainly comprises a valve body, a silica gel membrane and a valve cap, when the pressure in the breathing loop is increased, the gap between the silica gel membrane and the air leakage hole is reduced, although the flow rate is increased, the air leakage area is reduced, so that the air leakage is kept constant, and the air leakage of the platform valve is unrelated to the pressure in the pipeline; the three independent expiratory valves are all air valves with constant deflation, so that the lung pressure of the patient is continuously at the same constant value, and the air pressure of the lung of the patient can be influenced when the ventilation quantity of the respirator is changed or the air leakage holes of the air valves are uneven, so that the patient is in a very uncomfortable state.
