Ventilator-assisted ventilation is an important treatment for critically ill patients. During the treatment process, inhalation of drugs directly acts on the airway mucosa, and nebulized inhalation treatment for ventilator patients can improve ventilation function and prevent or control respiratory infections.

At present, in clinical application, medical staff generally add nebulized inhaled medicine to the nebulizer, and then connect the nebulizer to the breathing circuit for nebulization treatment. In this process, the airtight space between the patient and the ventilator is inevitably The loop is broken. After the nebulization is over, if the nebulizer is taken out, the breathing circuit will be disconnected again; if the nebulizer is not taken out, the drug storage chamber where the nebulized inhalation drug was originally placed will increase the ineffective dead space of the breathing circuit, and condensation will easily remain water. This process needs to repeatedly open the circuit between the patient and the ventilator, interrupting the normal operation of the ventilator, which undoubtedly increases the chance of the patient's airway infection, and also increases the chance of the external environment being polluted by the patient's droplets or airway secretions , it is difficult to meet the hospital infection management standards, while increasing the workload of medical staff.
