The splitter assembly may include a first splitter 31 and a second splitter 32. The first branching device 31 is used to divide the main air supply duct 21 into two air

supply branch ducts

411 and 412. The second splitter 32 serves to split the above-mentioned main exhaust gas line 22 into two

exhaust branch lines

421 and 422. It should be noted that the number of the two air

feeding branch pipes

411 and 412 and the exhaust branch pipes 421 and 42 are exemplary, and those skilled in the art can adjust the number of the air feeding branch pipes and the exhaust branch pipes according to the requirement, and such changes do not depart from the scope of the present disclosure.

In the operating state, an air supply branch line and an air exhaust branch line supply air to a patient and exhaust air exhaled by the patient. Since the first splitter 31 and the second splitter 32 may have the same configuration, the first splitter will be described as an example. The first splitter can be formed by connecting a plurality of T-shaped pipes or Y-shaped pipes. For example, two air supply branch pipelines can be separated by connecting a T-shaped pipe with the main air supply pipeline. For another example, one end of one T-shaped pipe is connected to the main air supply pipeline, and then the other two ends of the T-shaped pipe are connected to one T-shaped pipe, so that the main air supply pipeline can be divided into four branch air supply pipelines. It should be noted that, the number of the T-shaped pipes may be adjusted by those skilled in the art according to actual situations.

By way of example, the disinfection spraying device may include a liquid storage tank for storing disinfection liquid, and a liquid outlet pipe connected to the liquid storage tank, and the liquid outlet pipe may extend into the second gas storage bin. Furthermore, a valve can be arranged on the liquid outlet pipeline. The valve is opened within a predetermined time, and after a predetermined amount of disinfectant is sprayed, the valve is closed.

The medical staff can know the breathing condition of the patient, so that the gas flow in the gas supply branch pipeline can be adjusted.

In an optional implementation manner of some embodiments, a flow rate adjusting member may be further disposed on the gas supply branch pipeline, and the flow rate adjusting member is configured to adjust a flow rate of the gas in the gas supply branch pipeline according to the gas flow rate monitored by the gas flowmeter.
