A novel automated device - BABYLAT Enricher - concentrates the protein fraction from human milk on-site in hospitals. This innovative proprietary device allows fast and efficient protein extraction from human milk in a short time and no analogous automated devices are available on market. Premature infants with very low birth weight (<1.5kg) need four times higher protein contents than human milk alone can provide (most optimal food for any neonate). Without additional fortification of human milk by extra-protein content, these infants cannot gain weight leading to lifelong neurodevelopmental disorders. Around 1.5%-3% of all neonates have a very low birth weight and need protein-enriched milk daily during the first 2-3 months of their lives.
