  • Patent number: 10646671
    Abstract: Systems and methods for improving airway patency are disclosed. An oral device is positioned in the oral cavity and applies a negative pressure to the oral cavity. The oral device has pressure delivery ports directed toward an anterior surface of the soft palate when positioned therein. The negative pressure generates an air flow out of the oral cavity. A pressure tube is coupled to the oral device to provide the applied negative pressure. A pressure source is coupled to the pressure tube to generate the applied negative pressure. A collector is coupled to the pressure tube and/or pressure source to collect liquid, typically saliva, from the air flow out of the oral cavity. The collector is disposed outside of the oral cavity and coupled to the oral device.

  • Patent number: 10426905
    Abstract: Apparatuses and methods for improving airway patency are provided. A medial surface of the patient's tongue is constrained with a tongue constraint of an oral device placed in the oral cavity to generate a clear region between the medial surface and the hard palate. The clear region is in fluid communication with the soft palate. The tongue constraint has superior surface and inferior surfaces configured to generate the clear region. Negative pressure is applied within the oral cavity to hold the soft palate in a position in which the airway is at least partially open. The negative pressure is applied through one or more ports of the oral device. The one or more ports remain unobstructed by the tongue when the negative pressure is applied. The applied negative pressure causes the soft palate and tongue form a seal whereby the patient's airway is substantially fluidly isolated from the clear region.

  • Patent number: 10245175
    Abstract: Systems for maintaining a vacuum in a patient's oral cavity comprises an oral device, a vacuum control system, and an assembly including first and second tubes for connecting the vacuum control system to the oral device. The oral device has an internal plenum, and a vacuum is drawn in the plenum by a vacuum pump connected by a first tube of the tubular assembly. The vacuum is maintained by an air source which is connected to the plenum by the second tube of the tubular assembly. By maintaining a constant circulating air bleed through the oral device and the connecting tubes, saliva may be removed from the system and collected in a saliva trap located before the vacuum pump.

  • Patent number: 9763759
    Abstract: A saliva collector comprises a reservoir, a bubble barrier, and a membrane, where the bubble barrier and membrane are arranged in tandem on a flow path from an inlet to an outlet on the reservoir. Air aspirated from a patient's oral cavity enters the reservoir through the inlet, passes through the bubble barrier to remove foam and bubbles, passes through the membrane to remove entrained liquid saliva, and passes out through the outlet.

  • Publication number: 20170216085
    Abstract: An oral device for temporary placement in a patient's oral cavity includes upper and lower jaw braces and a tongue-engaging member. The upper and lower jaw braces are connected so that the lower jaw brace is advanced in an anterior direction relative to the upper jaw brace when the upper and lower jaw braces are closed together. A partial vacuum is drawn in the oral cavity and the vacuum and lower jaw displacement together control the position of the tongue in order to clear the patient's airway to reduce sleep apnea or treat other conditions.

  • Patent number: 9610190
    Abstract: An oral device for improving airway patency includes a tongue constraint and a negative pressure source. The tongue constraint engages the patient's tongue to maintain a clear region below the palate in an oral cavity and allow an anterior portion of the tongue to rise. By applying a negative pressure in the clear region, an airway behind the soft palate or tongue of the patient can be maintained. The tongue constraint is usually connected to an anchor. The anchor may be held between the patient's teeth or may engage the inferior surface of the palate. Another oral device for improving airway patency includes a lateral tongue structure and a negative pressure source.

  • Publication number: 20150107603
    Abstract: A saliva collector comprises a reservoir and a flow path from an inlet to an outlet on the reservoir. Air aspirated from the patient's oral cavity passes through an antechamber before reaching the reservoir. The antechamber is shaped to promote the collapse of any bubbles, allowing liquid saliva to drop from the antechamber to the reservoir.
