呼吸机及其供气控制方法
By designing a multi-channel switching device and controller, the ventilator can automatically adjust under different gas source conditions, solving the problem of insufficient oxygen concentration when there is no central gas supply system, ensuring respiratory support for patients, and achieving gas supply control without relying on a central gas supply system.

AI Technical Summary
Existing ventilators cannot provide the required oxygen concentration mixture in a timely manner when there is a lack of a central gas supply system or the gas supply system is unstable, which makes it impossible to effectively save patients.
A ventilator was designed, comprising multiple airways and a switching device, capable of switching between different air sources. Through the cooperation of pressure sensors and controllers, the airway connection mode is automatically adjusted to ensure the supply of mixed gas with the required oxygen concentration. The ventilator includes a first airway, a second airway, a third airway, an inspiratory branch, and a switching device, achieving air supply control independent of a central air supply system.
It enables timely delivery of mixed gases with the required oxygen concentration under different gas supply conditions, ensuring respiratory support for patients and improving the reliability and effectiveness of ventilators in environments lacking a central gas supply system.
