The Advanced 24-Week Preterm Infant Model (JY/FT331A) is a highly realistic simulator designed for neonatal and NICU training, specifically replicating the physiological features of extremely premature infants. Weighing less than 2500 grams and measuring under 47 cm in length, this model accurately depicts the delicate anatomy of a 24-week preterm newborn.

Key anatomical and physiological features include:

• Thin, reddish skin revealing underlying veins, soft facial skin with wrinkles, weak neck muscles, and low limb muscle tone.

• Premature infant characteristics such as abundant lanugo, soft ear cartilage, underdeveloped areola, and visible physiological jaundice.

• Male infants display undescended testes, while female infants have incomplete labial coverage.

The model supports comprehensive hands-on training, including:

• Anterior fontanel palpation and cranial suture assessment

• Preterm infant care in an incubator, including cleaning and bathing

• Suctioning and nasal feeding (gavage) practice

Constructed with high-quality materials that mimic real infant skin and tissue, the JY/FT331A model is ideal for medical students, neonatal nurses, and pediatric residents to develop essential skills in premature infant care. Its realistic features enhance clinical confidence and ensure safe, repeatable practice for both teaching and evaluation purposes.
