A kind of lung breathing assistance control device and ventilator

Abstract

The invention discloses a lung breathing assist control device and a ventilator, and relates to the field of lung breathing. A lung breathing assist control device includes: a memory, a processor, and a computer program stored in the memory and capable of running on the processor. The computer program is a lung breathing assist control method. When the processor executes the program, it implements the following steps: measuring the first displacement of the human thorax produced by the two processes of exhalation and normal inhalation during normal calm breathing; Collect in real time the second displacement of the chest during exhalation and normal inhalation when equipped with a ventilator; calculate the deviation value of the first displacement and the second displacement; determine based on the deviation value The amount of air a ventilator supplies to inflate the lungs. In order to solve the problem that differences in patient status make ventilator flow control complex and require higher requirements for air leakage detection.

Description

technical field [0001] The invention relates to the field of lung breathing, in particular to a lung breathing assist control device and a ventilator. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. The ventilator inflates the lungs, inhales and exhales Conversion, expulsion of alveolar gas and conversion from exhalation to inhalation, and the cycle repeats in turn. When infants and young children are complicated with acute respiratory failure, aggressive conservative treatment is ineffective, breathing is weakened, sputum is thick and thick, sputum discharge is difficult, airway is blocked or atelectasis occurs, tracheal intubation and ventilator should be considered. [0003] At present, ventilators are divided into two categories according to the type of use or applic...

AI Technical Summary

Problems solved by technology

[0009] In view of this, the present invention provides a lung breathing assistance control device and a ventilator. The physical change of the displacement of the thorax is used to determine the amount of air supplied by the ventilator to the lungs, so as to solve the difference in patient status that makes the flow control of the ventilator complicated and requires Problems with demanding air leak detection
