The Baby Flaem neonatal mucus aspirator for children is a patented system that involves the simple and repetitive action of pressure with the finger on the plunger for operation and does not require mouth aspiration by the mother. When it is released, the depression that is created gently sucks out the mucus, all this without removing the device from the baby's nose. In fact, its configuration allows the air to exit from the special slots prepared at the base of the central body, avoiding causing dangerous and annoying pressure inside the child's nose-ear ducts. The ease of disassembly and reassembly of the device also allows convenient cleaning and sanitization of the entire device.
