Publication number: 20110192404Abstract: This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection to mouth and helps a patient's upper and lower lips closed during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft tissue in a forward direction, the patency of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth preventing air from entering the oral cavity from atmosphere. The negative pressure will also pull the soft palate into contact with the rear surface of the tongue to create a seal that prevents the air from entering the oral cavity through the nasal airway.Type: ApplicationFiled: February 4, 2011Publication date: August 11, 2011Applicant: SOMNICS, INC.Inventor: Chung-Chu CHEN

Patent number: 7837944Abstract: A flow unit for microfluidic particles separation and concentration is disclosed. The unit comprises a nozzle segment, a turn segment, and a diffuser segment. The nozzle segment is defined by a first member and a second member, and has an opening through which fluid and microfluidic particles enter. The nozzle segment has a narrowing portion at which the first and second members narrow from the opening to increase momentum of the fluid therethrough. The turn segment is defined by the first member flaring outwardly downstream from the narrowing portion to change flow direction of the fluid consistent with the first member. The diffuser segment is defined by the second member extending past the turn segment to facilitate separation of the microfluidic particles from the fluid due to the inability to follow the fluid flow.Type: GrantFiled: November 5, 2008Date of Patent: November 23, 2010Assignee: Wayne State UniversityInventors: Gregory W.
