Embodiment Construction

[0033] The present invention proposes a man-machine synchronization scheme for invasive ventilators (for example: traditional ICU ventilators) in NIV mode, specifically, through the pre-established air leakage estimation model, the air leakage of the man-machine interface is estimated, thereby utilizing The leakage flow compensates the basic flow to improve the man-machine synchronization performance.

[0034] see figure 1 , which is a flow chart of the method for man-machine synchronization of the invasive ventilator in the non-invasive ventilation mode of the present invention, the method includes the following steps:

[0035] S101: measure airway pressure, inspiratory flow and expiratory flow;

[0036]S102: Using the pre-established air leakage estimation model, calculate the air leakage flow according to the airway pressure, inspiratory flow and expiratory flow;

[0037] S103: Compensating the basic flow by using the leakage flow.

[0038] Further, the present invention...

Abstract

The invention discloses a method and a device for man-machine synchronization of an invasive respirator in a noninvasive ventilation mode. The method comprises the following steps: measuring so as to obtain airway pressure, inspiration flow and expiration flow; according to a preset leakage estimation model, calculating the airway pressure, the inspiration flow and the expiration flow so as to obtain leakage flow; and compensating the basic flow by using the leakage flow. According to the method and the device, the leakage flow is estimated through the leakage estimation model, and the leakage compensation is realized, so that the purposes that the invasive respirator is improved so as to carry out noninvasive ventilation, and the man-machine synchronous performance is improved, are achieved.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a method and device for man-machine synchronization of an invasive ventilator in a non-invasive ventilation mode. Background technique [0002] According to the connection method with patients, ventilators are divided into invasive ventilators and non-invasive ventilators. Among them, invasive ventilators are connected to patients through airway intubation, and non-invasive ventilators are connected to patients through face masks or nasal masks. Invasive ventilators, such as traditional ICU (Intensive Care Unit, Intensive Care Unit) ventilators, generally use a limb ventilation circuit with an exhalation valve, which was originally designed for invasive ventilation. , NIV), they increase the non-invasive ventilation mode. NIV mode is a type of mode in which patients with spontaneous breathing ability are ventilated through man-machine interfaces (such as masks, nasal masks, ...
