Title:
MEDICAL VENTILATION DEVICE, CONTROL METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/232268
Kind Code:
A1
Abstract:
A medical ventilation device, a control method, and a storage medium. When the medical ventilation device is in a high-frequency inhalation stage, a high-frequency oscillation generation device (30) is controlled to generate high-frequency oscillation for a gas in an inhalation branch (20) according to a preset high-frequency oscillation frequency, and the gas is output through the inhalation branch (20) and a patient pipe (70) under the action of the high-frequency oscillation; when the medical ventilation device is in a high-frequency expiration stage, a working state of a venting means (50) and a working state of an electric gas pumping means (60) are adjusted according to set ventilation control parameters and a measured patient-side pressure, and in the process of adjusting the working states, the working state of one of the venting means (50) and the electric gas pumping means (60) is adjusted with reference to the working state of the other one, so that adjustments to the working states of the two means will not affect each other, and then ventilation control parameters of the medical ventilation device are consistent with the set ventilation control parameters by means of the adjustments to the working states of the venting means (50) and the electric gas pumping means (60), thereby improving control precision and stability.
