Abstract

The invention relates to a total liquid ventilation respirator, and aims at providing a respirator which can accurately regulate and control respiration parameters and carry out feedback regulation. According to the technical scheme, the total liquid ventilation respirator comprises a liquid conveying channel. The liquid conveying channel comprises an oxygenator assembly, a buffer pool and a piston pump assembly. The oxygenator assembly comprises a first oxygenator and a second oxygenator, wherein the upper portion of the first oxygenator and the upper portion of the second oxygenator are communicated through a catheter, and the lower portion of the first oxygenator and the lower portion of the second oxygenator are respectively provided with a gas inlet for outside source oxygen. The upper portion of the buffer pool is communicated with the second oxygenator through a catheter. The piston pump assembly is composed of an inspiration piston pump and an expiration piston pump, wherein a liquid inlet of the inspiration piston pump is communicated with the lower end of the buffer pool through a catheter, a Y-shaped catheter is arranged between the inspiration piston pump and the expiration piston pump, a first end of the Y-shaped catheter is connected with a liquid outlet of the inspiration piston pump, a second end of the Y-shaped catheter is connected with a liquid inlet of the expiration piston pump, a third end of the Y-shaped catheter is connected with the lung of a patient, and a liquid outlet of the expiration piston pump is communicated with the first oxygenator through a catheter.

Description

technical field [0001] The invention relates to a medical device, in particular to a complete liquid ventilation ventilator. Background technique [0002] Complete liquid ventilation technology is a new type of respiratory therapy technology for the treatment of acute respiratory distress syndrome. Its principle is to completely replace the gaseous respiratory medium in the lungs with a liquid (perfluorocarbon) with high solubility for oxygen and carbon dioxide, and apply liquid ventilation. The ventilator injects oxygenated liquid into the lungs for gas exchange, then expels the liquid containing hypertonic carbon dioxide from the body, and oxygenates and removes carbon dioxide in the oxygenator. Multicenter randomized controlled animal experiments of complete liquid ventilation and traditional mechanical ventilation have confirmed that complete liquid ventilation can significantly improve the body's gas exchange, protect the normal tissue morphology of the lungs, inhibit t...
