The assist of respiration for the premature babies based on nasal CPAP (Continuous Positive Airway Pressure) is one of the important medical treatments. Some devices of nasal CPAP have been developed, however they give some kinds of installation load to the babies. In order to decrease the load, the down sizing of the devices and the improvement of the installation method are required. A new type device of nasal CPAP has been developed for adapting these requirements. The device operates fluid-dynamically in switching mode of jet flow by the similar mechanism of a fluidics device. The fundamental characteristics in fluid dynamics have been investigated experimentally by using techniques of qualitative and quantitative visualization.
