The application discloses a kind of lung respiratory compliance value detection data processing methods, comprising the following steps: setting experimental animal grouping situation and each group quantity requirement, set data exception and exclusion standard;Run a level experiment, obtain a level experimental data and judge according to a level acceptance standard, obtain a level processing result;Carry out two levels of experiment, obtain two levels of experimental data and judge according to two levels of acceptance standard, obtain two levels of processing result;Carry out three levels of experiment, obtain three levels of experimental data and judge according to three levels of acceptance standard, obtain three levels of processing result;According to the processing result of each level obtained in the above steps, the final result of test substance is obtained.The method of the application constructs the specific method of lung respiratory compliance value detection data processing, guarantees data quality from the source, improves accuracy through hierarchical verification, and provides reliable efficacy evaluation basis.

The utility model belongs to the technical field of medical apparatus and instruments, and concretely relates to a gas circuit device for simulating lung respiration demonstration, which comprises three-way valves, connecting pipes and air bag simulation lungs. The air bag simulation lungs are multiple and are respectively paired with the multiple three-way valves. The pipe opening at one end of the first three-way valve is connected with the pipe opening of the second three-way valve through the connecting pipe. The pipe opening at the other end of the three-way valve is connected with the air bag simulation lung. The gas circuit device is connected with the breathing machine, the various valves and clamps are adjusted, and the corresponding waveform changes and other parameters in the digital display screen of the breathing machine are observed, so that the correlation between the breathing machine setting and the pathological state of the lung of the sick child is understood, the gas circuit device of the simulation lung has high visibility and operability in the teaching machine training, and helps to cultivate the clinical thinking and practical ability of the trainees.

The present application relates to the technical field of drug efficacy and activity testing, and discloses a method for evaluating the biological activity of a pulmonary surfactant. In the method for evaluating the biological activity of a pulmonary surfactant provided by the present application, neonatal rabbits with pulmonary surfactant deficiency are selected as experimental subjects, and the effect of a test pulmonary surfactant on improving lung compliance in the neonatal rabbits is assessed through pulmonary administration; the experimental data results are used as the basis for evaluating whether the drug efficacy and biological activity meet requirements. The method provides high accuracy, reproducibility, and sensitivity, involves simple operational steps, and has broad applicability.
