Working process of ventilator

The pressure of the patient gas is generated by the turbo pump inside the machine. Working process: The air enters the safety valve through the filter. The opening of the safety valve and the speed of the pump are controlled by the CPU. The pressure and capacity of the ventilation are set by the doctor according to the needs of the SARS patient. Enter the human body mask and enter the human body, that is, the positive pressure is sucked; the one-way valve is closed, the suction pressure is reduced, and the positive pressure of the patient’s lungs automatically flows out, which is exhaled through the mask.

The pressure of the patient gas is injected, the oxygen pressure of the oxygen cylinder and the positive pressure air are generated.
