lune is a holistic training and monitoring system that allows sleep apnea patients a safe sleep by stimulating oral muscles through electrodes. The product‘s design and concept embodies a whole new approach compared to traditional CPAP masks. The difference to conventional methods and products is that not only the symptoms of sleep apnea disease are reduced, but the patient gets the opportunity to achieve a permanent and sustainable improvement of the disease by strengthening the oral muscle. The "lune system is equipped with sensors that measure the angle of the head and breathing during a sleep period. If the tongue slides into the throat, electrodes start to stimulate the area. The swallowing sensation is triggered. When swallowing, the tongue returns to its optimal position. In addition, the electrodes strengthen the muscles of the mouth, which means that a possible improvement of the disease can occur.
