The oral feeding disorder is common in preterm infants. It not only shows the adverse effect for growth and neurodevelopment in clinical but also becomes one of the important indicators of high risk group for neurodevelopment delay in preterm infants. The preterm infants must coordinate the motor patterns of sucking, swallowing, and breathing skillfully to avoid chocking, aspiration, oxygen desaturation, bradycardia or apnea episodes. However, there is no objective and complete monitoring system for oral feeding in preterm infants. The judgment and classification severity in preterm infants are mostly subjective and phasic evaluations. In this study, a non-invasive and wireless multi-channel monitoring system for oral feeding in preterm infants was developed to continuously monitor sucking pressure, swallowing sound and chest movement. Next, the oral feeding efficiency and possible risk group in preterm infants were shown by simple graphic interface. Finally, the experimental results indicated that sucking and swallowing frequencies in term infants are significantly different from preterm infants.
