Ventilator structure and working process

        Ventilator structure: The pressure of the patient's gas is injected by the in-machine turbo pump. Engineering process: the atmosphere enters the demand valve through the filter. The size of the opening of the demand 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, and the appropriate amount of gas is adjusted through the check valve. Entering the human face mask and entering the human body, that is, inhaling positive pressure; the one-way valve is closed, the suction pressure is lowered, and the positive pressure of the patient's lungs is automatically discharged, that is, exhaled through the mask. The pressure of the patient's gas is injected, the oxygen pressure of the oxygen cylinder and the positive pressure air are generated.

      Working process: Medical oxygen is mixed into the gas storage tank through the pressure reducing valve and the air passing through the filter. The flow regulator is controlled by the CPU. The pressure and capacity of the ventilation are set by the doctor according to the needs of the SARS patient, and the appropriate amount of gas is adjusted through the one-way. The valve enters the human body mask and enters the human body, that is, the positive pressure is sucked. When the patient exhales, the one-way valve is closed, the suction pressure is lowered, and the patient's lungs are automatically sucked out by the positive pressure, that is, exhaled through the mask.
