Description

Devices, systems, and methods for minimizing fat loss in collection and feeding of human breast milk Cross Reference to Related Applications The present application claims the benefit and priority of U.S. provisional patent application serial No. 63/583,881 filed on day 20, 9, 2023, and claims the benefit and priority of U.S. provisional patent application serial No. 63/562,812 filed on day 8, 3, 2024, which are incorporated herein by reference in their entirety. Background The present disclosure relates generally to medical devices, and more particularly, to apparatus, systems, and/or methods for minimizing nutrient loss during collection, transfer, and feeding of human breast milk. Neonatal Intensive Care Unit (NICU) is a neonatal ward in hospitals that provides specialized medical care for premature infants (meaning infants less than 37 weeks gestation), low birth weight infants, or infants in need of continuous care for health conditions. Of the 1.4 million infants born annually worldwide, 1500 ten thousand premature birth increases their susceptibility to health challenges due to blocked intrauterine development.
