Problems solved by technology

[0002] According to the current domestic clinical methods for the treatment and rescue of acute respiratory distress syndrome, mechanical ventilation methods such as non-expiratory positive pressure ventilation, split-lung ventilation, and inverse ratio ventilation are basically used. In the fight against "SARS", it is necessary to cut the trachea for oxygen supplementation for patients with serious conditions, which will not only easily cause lung tissue damage, make it difficult to reduce the mortality rate, but also increase the risk of infection for medical staff

preparation example Construction

[0012] The preparation method of lung cavity ventilation liquid is characterized in that: the preparation method comprises the following steps, a. adding potassium hydrogen fluoride into the first-stage reactor, and heating at 60-120°C for reaction, and the new ecological fluorine produced is directly put into React with metal cobalt in the second-stage catalytic reactor to directly produce cobalt trifluoride and heat the reactor to reach 150-350°C; b, take naphthalene and dissolve it in an evaporator filled with decahydronaphthalene, and the mixture of naphthalene and decahydronaphthalene The weight ratio is 1:1-1:10. Heat the evaporator to evaporate the solution and add it to the reactor in a gaseous state. The reaction product is collected in the crude product container; c. After the feeding is completed, the collected product in the crude product container is washed with distilled water , and dried over anhydrous sodium sulfate to obtain the crude product perfluorodecalin, ...
