A custom, sized and fitted, integrated oral appliance is provided to treat breathing obstruction and restriction in the upper airway during sleep. Several novel features are integrated in a single device, which includes mandible repositioning to open the airway, and tongue restraint to prevent airway blockage. This device is comprised of a built-in air conduit to bypass nasal restriction and airway occlusion. In operation, the appliance is positioned in the oral cavity to firmly grip the upper and lower dentition using customized unshaped trays. Appliance positioning advances the mandible to an adjustable predetermined position and simultaneously restrains the tongue using flexible bristles attached to a spring-loaded, tongue-restraint-ac (TRAC) component. A hollow air conduit, built into the TRAC, spans the area between the users' lips and soft palate. It facilitates the flow of self-heated, moisturized air directly to (and from) the oropharynx to bypass airway obstructions and/or nasal restrictions.

In accordance with one embodiment of the invention, there is provided a wound drainage system for draining fluid from a wound of a patient. The system includes a drain catheter. A suction means applies suction at the drain catheter such that fluid is drawn from the wound. While drawing fluid from the wound, a controller periodically increases and decreases the application of suction at the drain catheter. This allows the tissue surrounding the wound drain to relax, thus preventing obstruction of the drain catheter.
