Abstract

A ventilator turbine volume-controlled ventilation method comprises the main steps of: the ventilator is started up, a control unit in the ventilator issues a rotation speed U control instruction to a turbine driver, the turbine driver drives a turbine motor, and then the control unit detects the breathing state of a patient, if the patient needs to inhale air, proceeds to an inhalation phase control, and, if the patient needs to exhale air, proceeds to an exhalation phase control, where the inhalation phase control is implemented by the control unit that outputs driving voltage V1 to regulate the extent to which an inhalation valve is opened, and the exhalation phase control is implemented by the control unit that outputs driving voltage V2 to regulate the extent to which an exhalation valve is opened.

Dependent claims

A ventilator turbine-based volume-controlled ventilation method, wherein a ventilator is provided with a turbine configured for providing an air source for the ventilator, and the ventilator turbine-based volume-controlled ventilation method comprises:

a step S00 of starting the ventilator, wherein a control unit in the ventilator sends a control instruction for controlling a rotation speed U to a turbine driver so that the turbine driver drives the turbine connected with the turbine driver;
a step S10 of detecting respiration status of a patient by the control unit, wherein the step S20 is performed if the patient needs inspiration and the step S30 is performed if the patient needs expiration;
a step S20 of outputting a driving voltage V1, by the control unit via inspiratory phase control, to adjust an opening degree of an inspiratory valve, wherein the step S30 is performed after the inspiratory phase control is finished;
a step S30 of outputting a driving voltage V2, by the control unit via expiratory phase control, to adjust an opening degree of an expiratory valve, wherein the step S20 is performed after the expiratory phase control is finished;
and
a step S40 of turning off the ventilator and stopping supplying air to the patient.
