The humidification and warming effect of a mechanical ventilation patient is lost or partially lost, the water evaporation of a respiratory tract is obviously increased compared with that of the respiratory tract in a normal and calm state, the cilia movement is weakened due to the dryness of the respiratory tract, the capacity of actively discharging secretions and foreign matters in the lung is reduced, the sticky and thick sputum is not easy to discharge, and the probability of lung infection is increased. Therefore, the mechanical ventilation patient adopts a humidification and warming method conventionally to solve the problem of lung infection caused by dry respiratory tract. However, the temperature in the whole breathing machine pipeline is not absolutely equal, and the temperature difference occurs in the breathing machine pipeline due to the change of the cold and heat of the gas caused by the reasons of intermittent sputum suction and the like, so that the moisture in the gas is condensed on the inner wall of the breathing machine pipeline, and further, condensed water is formed to flow in the pipeline. Considering that the pathogeny of patients treated by mechanical ventilation is lung infection, pathogenic bacteria are inevitably contained in exhaled air and condensed water, and the backflow of the condensed water can cause the incidence rate of ventilator-associated pneumonia to be increased. Therefore, the condensed water in the breathing machine pipeline is poured in time according to the water volume in the water accumulation cup clinically.
The liquid collecting cup or the liquid accumulating tank which is clinically used at present is small, if the liquid collecting cup or the liquid accumulating tank is not poured timely, the condensate water flows back after overflowing easily, and then the risk of lung infection is increased.
