Control method and device for improving effective utilization ratio of oxygen during noninvasive ventilation

Abstract

The invention provides a control method and device for improving the effective utilization ratio of oxygen during noninvasive ventilation. The control method and device are used for improving the synchronization of a ventilator and an oxygen generator by controlling the triggering of the oxygen generator through the ventilator. The control method comprises the following steps: a, acquiring pressure flow data generated when a user breathes; b, judging whether the user performs the inhaling action or not based on the pressure flow data; c, if the user performs the inhaling action, sending oxygen generation or / and oxygen supply control instructions to the oxygen generator; d, receiving feedback information of the oxygen generator in a working state M, wherein the feedback information corresponds to the control instructions. The invention further provides the corresponding control device. Through adoption of the control method and device, the portable noninvasive ventilator and oxygen generator can be cooperatively used when a patient is positioned outside or in other environments, and thus the patient can receive noninvasive positive-pressure ventilation treatment and oxygen therapy at the same time.

Description

technical field [0001] The invention relates to the technical field of medical equipment control, in particular to a control method and device for improving oxygen utilization rate during non-invasive ventilation. Background technique [0002] In modern clinical medicine, as a device that can replace, control or change people's normal physiological breathing, increase pulmonary ventilation, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity, it can prevent and treat Respiratory failure, reducing complications, saving and prolonging the life of patients, is widely used in respiratory failure caused by various reasons, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. The working principle of the existing ventilator is generally to use the pressure difference of the gas to realize the delivery or removal of gas to the patient's airway: when the patie...

AI Technical Summary

Problems solved by technology

In most cases, patients can only choose to use one of a ventilator or an oxygen generator to keep the patient's airway unobstructed or to obtain a gas with a high concentration of oxygen. An effective control method is not provided so that the ventilator and the oxygen generator can Effectively used together and working synergistically for patients who require both non-invasive positive pressure ventilation therapy and oxygen therapy
