US Patent 7195018 Adjustable support system for nasal breathing devices

Two nasal breathing devices are supplied with continuous positive airway pressure for alleviation of sleep apnea. The two nasal breathing devices are each supported on a spiral flexible supply tube. The supply tubes pass through a block. The block is supported on the patient's head below his nostrils. A stop nut is threaded on each of the spiral flexible supply tubes. The supply tubes and nasal breathing devices are individually adjustable by rotating the stop nut on each of the supply tubes. In this way, the nasal breathing devices are individually adjusted for proper nasal contact and sealing.
