After years of exploration and a lot of research and testing, this device has been developed to focus on solving problems quickly. Simple and easy operation can quickly achieve the effect of assisting breathing. After the birth of daily animal newborns, breathing difficulties often occur. Most of the methods are to directly assist breathing. In this process, it is easy to blow the amniotic fluid in the nasal cavity into the lungs and cause death. Also experienced farmers will first lift the piglet's hind legs, quickly throw the amniotic fluid out, and then assist breathing, but this approach not only requires mastery of strength skills, but also requires years of clinical experience. The neonatal ventilator uses the principle of negative pressure adsorption, which not only solves the problem of amniotic fluid choking into the respiratory tract, but also assists breathing quickly.
