Intelligent APRVplus ventilator ventilation system and a use method thereof

Abstract

The invention relates to an intelligent APRVplus ventilator ventilation system and a use method thereof. The intelligent APRVplus ventilator ventilation system comprises an inspiratory circuit and anexpiratory circuit, a microcomputer electronic controller and an airway system for detecting and controlling the inspiratory circuit and the expiratory circuit. The pneumatic system includes a flow sensor, a pressure sensor, a pressure relief valve and a proportional solenoid valve. The suction loop is provided with a flow sensor and a pressure sensor, and the expiration loop is provided with a flow sensor, a pressure sensor, a pressure release valve and a proportional solenoid valve. The microcomputer electronic controller detects the respiratory frequency, airway pressure, gas flow rate andtidal volume of the airway system through a flow sensor and a pressure sensor, and adjusts the airway system through an expiratory circuit pressure relief valve and a proportional solenoid valve. Through the technical scheme, aRDS intelligent precision, safety and effective lung protective ventilation can be realized, and manpower and material resources can be saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent APRVplus ventilator ventilation system and a use method thereof. Background technique [0002] Mechanical ventilation is used in the respiratory support treatment of respiratory failure caused by various reasons, general anesthesia, major surgery, etc. It is also used in the rehabilitation of various chronic neuromuscular diseases, cardiac insufficiency and various respiratory diseases. With the development of microelectronics technology, the performance and functions of modern ventilators are becoming more and more perfect and improved, the ventilation control is more precise, and the safety is getting higher and higher. In the past ten years, with the update of the concept of mechanical ventilation and the popularization of mechanical ventilation technology, the efficacy of modern ventilators in critically ill patients with respiratory failure has been si...

AI Technical Summary

Problems solved by technology

However, the general treatment effect of mechanical ventilation technology on patients with severe respiratory failure, especially ARDS patients, is still not ideal, and the prognosis of patients has not been further improved.

With the continuous deepening of the understanding of respiratory pathophysiology, the technology and function of modern ventilators cannot meet the requirements of the respiratory support level of critically ill patients, and there are still many problems that need to be improved:

[0003] 1. The function is relatively limited, it can only provide ventilation support, and cannot dynamically provide important physiological indicators (such as end-tidal CO 2 and oxygenation indicators), may lead to adverse reactions to ventilation

[0004] 2. At present, the ventilator cannot dynamically adjust the parameters of the ventilator in real time according to the dynamic lung ventilation and ventilation indicators. It is necessary for medical personnel to additionally detect these indicators and then manually adjust them.

Due to the very limited number of professionals, and it is very time-consuming and labor-intensive, the application of the advantageous APRV ventilation mode is generally limited to simple and basic applications, and cannot play its due functions and roles.

Especially in recent years, our research has proved that the pathophysiologically oriented APRV ventilation program (APRVplus) in the treatment of ARDS can effectively improve the prognosis of patients. Due to the above reasons, it is difficult to popularize it to benefit patients
