Multifunctional respiratory therapy system and method for hospital and family environments

Abstract

The invention discloses a multifunctional respiratory therapy system for hospital and family environments. The multifunctional respiratory therapy system comprises a control unit, a ventilation unit and an oxygen generation unit; due to self oxygen generation through an oxygen supply unit, the problem that the existing respiratory therapy equipment completely depends on an external oxygen source is solved; low/high flow oxygen therapy, intelligent oxygen supply control and non-invasive positive-pressure mechanical ventilation therapy functions are integrated into a whole; corresponding therapeutic working modes can be started according to different requirements of different stages of respiratory diseases of patients; and therefore, seamless switching and multiple purposes by one machine invarious therapeutic schemes can be realized. According to the multifunctional respiratory therapy system and method for hospital and family environments in the invention, closed loop control of bloodoxygen concentration, respiratory synchronized trigger pulse oxygen supply or respiratory synchronized on-demand oxygen supply technologies are adopted; oxygen supply is only carried out in the inspiratory phase of a patient; stimulation of an airflow on the upper respiratory tract when continuous flow oxygen therapy is carried out is reduced; the comfort and the compliance of the patient are improved; and simultaneously, oxygen resource waste is reduced to the most extent.

Description

technical field [0001] The invention relates to the technical field of respiratory therapy, in particular to a multifunctional respiratory therapy system and method used in hospitals and home environments. Background technique [0002] According to the patient's respiratory disease from mild to severe, respiratory treatment generally adopts low-flow oxygen therapy, high-concentration oxygen therapy, non-invasive mechanical ventilation and invasive mechanical ventilation in sequence; invasive mechanical ventilation, non-invasive mechanical ventilation, High-concentration oxygen therapy and low-flow oxygen therapy treatment plan, but the current respiratory treatment equipment in the hospital has a relatively single function, and it is very troublesome to replace the treatment equipment with different respiratory treatment plans. [0003] At the same time, most of the existing respiratory therapy equipment uses an external oxygen source for respiratory therapy. Usually, the ho...

Problems solved by technology

Moreover, the oxygen supply method of continuous flow is adopted, and this oxygen supply method will actually cause a great waste of oxygen.

Because when a normal person breathes, the duration of the inspiratory phase and the expiratory phase are different. During the whole breathing process, the oxygen provided by continuous oxygen supply is only (1/3)×(3
