The air cut heat and moisture exchanger is made of super high molecular material as the main raw material. It is composed of threaded pipe or extension pipe, shell, humidifying material, filter material, patient interface and machine interface. The main humidifying material is sponge or absorbent paper, and the filter material is polypropylene membrane or polypropylene filter membrane.
The air cut heat and moisture exchanger is used to humidify, warm and filter the gas coming out of the ventilator and entering the patient's respiratory system. It is disposable and is clinically used for humidifying and filtering the gas of mechanical respiration of severe and anesthetized patients.
When the patient exhales, the gas equivalent to body temperature and saturated humidity enters the inner side of the hygroscopic condensation humidifier for condensation, and releases the heat stored in steam state at the same time; When inhaling, the external dry gas is humidified and warmed when it passes through the hygroscopic condensation humidifier. In this way, it circulates back and forth, and constantly uses the heat and humidity in the exhalation to warm and humidify the inhaled gas.
