Medical Devices and Medical Equipment Design iNAP Sleep Apnea Treatment by Somnics, Inc. The iNAP is designed to provide a comfortable sleep experience for OSA (Obstructive Sleep Apnea) patients. During sleep, the iNAP system creates a gentle vacuum within the oral cavity by stabilizing the tongue, thereby keeping the airway open. Unlike traditional CPAP machines, the iNAP system works without a face mask or a bulky machine and instead uses a discreet soft oral interface and a pocket-sized console. The system provides a simple and intuitive user interface with a built-in rechargeable battery and an easy-to-clean saliva container, making it a perfect travel companion.
