Respirator and using method

Abstract

The invention relates to the technical field of medical equipment, and discloses a respirator and a using method thereof. The respirator comprises an expiration flow sensor, an air supply flow sensorand a plurality of pressure sensors, a central processing unit, pressure adjusting equipment, an air supply gun and an exhalation valve, wherein the pressure sensors are used for measuring the air supply flow pressure and the expiration flow pressure and arranged on an air supply pipe and an expiration pipe; the central processing unit is used for receiving the data of the air supply flow sensor and the expiration flow sensor, comparing, integrating and calculating the data of the air supply flow and the expiration flow, and controlling the pressure adjusting equipment according to the integrated and calculated data and the data of the plurality of pressure sensors; the pressure adjusting equipment is used for adjusting the pressure of the air supply flow according to an instruction of thecentral processing unit and adjusting the pressure of the air supply flow; the air supply gun is used for conveying airflow with corresponding pressure according to data of the pressure adjusting equipment; and the exhalation valve is used for controlling and exhausting exhalation air flow. According to the respirator and the using method, the treatment success rate of the ARDS patient can be increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a ventilator and a usage method. Background technique [0002] Acute respiratory distress syndrome (ARDS) is a clinical syndrome characterized by refractory hypoxemia caused by intrapulmonary and / or extrapulmonary causes. The pathological basis is due to damage such as inflammatory response Factors lead to a large number of dorsal alveolar edema and collapse, alveolar diffusion dysfunction, resulting in intrapulmonary arteriovenous shunt, a large amount of pulmonary arterial blood cannot be fully oxygenated into the pulmonary artery to return to the blood circulation, hypoxemia is difficult to correct, and the mortality rate is high. Not only will it cause damage to the respiratory system, but in severe cases it can also lead to functional failure of the kidneys, gastrointestinal tract, and central nervous system. [0003] At present, commonly used lung recruitment met...

AI Technical Summary

Problems solved by technology

The present invention aims at the problems that the current prior art tends to cause shear damage in the border area between the atelectasis area and the normally ventilated alveolar area, resulting in a low survival rate after treatment and many serious complications after survival, and proposes a method that is more in line with physiological conditions. Lung recruitment ventilation mode to improve oxygenation, protect "baby lungs", improve survival rate after treatment, and improve post-survival complications
