Problems solved by technology

However, since the alveoli cannot be seen with the naked eye, and the effects of water and surfactant cannot be visually verified, the relationship between the alveolar surface tension in the alveoli and the alveolar surfactant is difficult to explain in the teaching process

Abstract

The invention discloses a pulmonary alveoli surfactant function experiment device and method. The device comprises a communication tube, a first balloon and a second balloon, and the first balloon iscommunicated with the second balloon through the communication tube. The device is simple in structure, the experiment method is easy to operate, the functions of water molecules and surfactants in the pulmonary alveoli under a microscopic condition are displayed through a macroscopic phenomenon, teachers are helped to explain and analyze knowledge points, and then students conveniently understandthe knowledge points.

Description

technical field [0001] The invention belongs to the field of medical teaching aids, and more specifically relates to an experimental device and method for the action of alveolar surfactant. Background technique [0002] The lung tissue is elastic, and the water in the alveoli has a surface tension pointing to the center of the alveoli, which is not conducive to alveolar inhalation; the surfactant in the alveoli can reduce the surface tension of the alveoli. Clinically, in the case of neonatal respiratory distress syndrome, methods such as supplementing pulmonary surfactant, mechanical ventilation, and supporting circulation to maintain normal blood pressure will be used, but all of them lack appropriate evaluation criteria and require preclinical trials. Water molecules form alveolar surface tension on the inner surface of the alveoli, which hinders alveolar expansion; lipid molecules between the interface of gas and water molecules in the alveoli can reduce the alveolar sur...
