Medical breathing machine in air duct positive-pressure high-frequency ventilating mode

Abstract

The invention discloses a medical breathing machine in an air duct positive-pressure high-frequency ventilating mode. The medical breathing machine adopts an air duct positive-pressure ventilating mode, a high-frequency pulse pressure wave with adjustable amplitude, frequency and duration is increased in the pressure level of an air duct positive-pressure ventilating mode, and the ventilating modes can be divided into at least seven types, namely single-level positive-pressure high-frequency ventilation, double-level inspiration phase high-frequency ventilation, double-level expiration phase high-frequency ventilation, double-level expiration and inspiration two-phase high-frequency ventilation, proportional ventilation inspiration phase high-frequency ventilation, proportional ventilation expiration phase high-frequency ventilation, and proportional ventilation inspiration phase and expiration phase high-frequency ventilation. By superposing vibration amplitude, vibration frequency and vibration time duration on different treatment pressures in different breathing sections to generate the high-frequency ventilating pressure of the air duct, the smoothness of the air duct and the increase of the pulmonary ventilation in ventilation treatment are achieved, and the blood oxygen concentration and the carbon dioxide concentration are adjusted.

Description

technical field [0001] The invention relates to a medical breathing apparatus, in particular to a medical ventilator in a positive airway pressure high-frequency ventilation mode. Background technique [0002] The existing clinical mechanical ventilation techniques are mainly divided into two categories: invasive and noninvasive. Noninvasive Positive Pressure Ventilation (NPPV) is a clinical technique for the treatment of a variety of respiratory failures. Non-invasive positive pressure ventilation technology is the use of non-invasive airway, positive pressure ventilation through mouth, nose or oronasal mask artificial airway. The basic idea is to ventilate through the mouth, nose or oronasal mask with single or double or multiple pressures during the inhalation and exhalation phases. The commonly used non-invasive positive pressure ventilation is bilevel positive pressure, which provides a higher pressure level at the airway opening during the inspiratory phase than that...
