The Penguin Suction Device, also known as the Penguin Newborn Suction, is primarily used to clear the nasal and oral passages of newborns and infants. It helps remove fluids, such as mucus, that can obstruct breathing or feeding. It's a simple, reusable, and durable device, often used in situations like basic newborn resuscitation courses, particularly in developing countries, to improve newborn outcomes.
