A method for preventing sleep apnea in a wearer comprises locating the top protrusion below and extending away from the top occlusal surface of a wearer's upper teeth, locating the bottom protrusion above and extending away from the bottom occlusal surface of a wearer's lower teeth and extending the adjusting block in an anterior direction from the top protrusion towards the bottom protrusion.
Description
APPARATUS FOR THE PREVENTION OF SLEEP APNEA
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates generally to sleep apnea in general and in particular to an apparatus for preventing sleep apnea in a wearer.
BACKGROUND OF THE INVENTION
1. Field of Invention The present invention relates generally to sleep apnea in general and in particular to an apparatus for preventing sleep apnea in a wearer.
2. Description of Related Art Sleep apnea is a disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. Sleep apnea disrupts the normal sleep patterns of the individual resulting in fatigue, moodiness, and decreased attention and drive. Sleep apnea can also potentially lead to serious health consequences, such as high blood pressure, heart disease and weight gain among others.
Sleep apnea commonly occurs when the soft tissue at the back of the individual's throat relaxes during sleep and collapses thereby partially or completely obstructing that person's airway. Such restriction also commonly causes the person to snore.
Conventional methods of treating sleep apnea have been to either provide supplemental oxygen to the individual while sleeping or provide a breathing device intended to reduce or prevent the restriction in their airway during sleep. Such attempts have previously been unsatisfactory. In particular, the provision of oxygen to a person typically requires providing a mask or tubes over or within the user's nostrils which may be uncomfortable for some users thereby further decreasing the amount of sleep that person is able to have in a night.
Similarly, devices intended to reduce airway restriction, have commonly focused on translating the lower jaw of the wearer in a forward direction so as to also lift the soft tissue responsible for the restriction. Such devices, however have been uncomfortable to wear by locking the patient's lower and upper jaws together thereby preventing the wearer from opening their mouth.
Examples of such devices may be found in US Patent Nos. 7,757,693 to Toussaint and 5,365,945 to Halstrom.
SUMMARY OF THE INVENTION
According to a first embodiment of the present invention there is disclosed an apparatus for preventing sleep apnea in a wearer comprising a generally u-shaped upper appliance adapted to engage with a user's upper jaw and a generally u-shaped lower appliance adapted to engage with a user's lower jaw. The apparatus further includes a bottom protrusion extending from the lower appliance in a direction generally away from an occlusal surface of the lower appliance and towards the upper appliance and a top protrusion extending from the upper appliance in a direction generally away from an occlusal surface of the upper appliance and towards the lower appliance, the top protrusion including an adjusting block having a height of between 5/16 and 13/32 of an inch adjustably extending therefrom, the adjusting block having a leading surface oriented to engage the top protrusion The adjusting block may include an anteriorly oriented leading face. The leading face may be angled from perpendicular to the upper appliance. The leading face may be angled by 70 degrees from horizontal. The bottom protrusion may include a posteriorly oriented surface corresponding to and adapted to engage the leading face of the adjusting block.
The adjusting block may be slidably movable relative to the top protrusion.
The adjusting block may include at least one slide rod extending therefrom, wherein each of the at least one slide rod is slidably supported within a corresponding bore in the top protrusion. The apparatus may further comprise two slide rods. The adjusting block may include an actuator for moving the adjusting block relative to the top protrusion. The actuator may comprise a threaded rod rotatably coupled to and extending from the adjusting block, the threaded rod being threadably received within the top protrusion.
