Abstract:
An embodiment of a collar includes first and second pressure surfaces, and first and second sealing surfaces. The first pressure surface is configured for disposal over a first region of a throat of a subject having an airway, and the first sealing surface is configured to form around the first pressure surface a first seal with a first region of a neck of the subject. And the second pressure surface is configured for disposal over a second region of the throat, and the second sealing surface is configured to form around the second pressure surface a second seal with a second region of the neck. For example, the collar can be configured to generate multiple negative-pressure regions to treat a subject's sleep apnea.
Abstract:
An embodiment of a system for treating sleep apnea includes a collar, a pump, and a motor. The collar has a vacuum surface and has a sealing surface that is configured to form a seal with a region of a neck of a subject having an airway. The pump is secured to the collar, and is configured to maintain the airway open by drawing a vacuum between the vacuum surface of the collar and a region of a throat of the subject. And the motor is secured to the collar and is configured to drive the pump. As compared to existing systems (e.g., a Continuous Positive Airway Pressure (CPAP) system) for treating sleep apnea, the above-described system may be more portable, more comfortable, may be less likely to require adjustment while a subject using the system is asleep, and, therefore, may be less likely to awaken the subject.
Abstract:
A system includes an apparatus and a controller, according to an embodiment. The apparatus is configured to maintain an airway of a subject open while the subject is sleeping by applying to the airway a pressure having a magnitude, and the controller is configured to cause the apparatus to change the magnitude of the pressure over a period that begins at a settable start time. For example, the system can be configured to treat a subject's sleep apnea with positive or negative pressure, and to function as an alarm clock by beginning to change the pressure magnitude at a settable start time, and to continue changing the pressure over a period with a settable duration (or settable stop time) to gently awaken the subject by the end of the period.
Abstract:
A system can perform the following procedure as part of a plan to treat sleep apnea, according to an embodiment. The system monitors a degree to which an airway of a subject is open, and monitors a condition that is related to the degree to which the airway is open. The system also correlates the condition to the degree to which the airway is open, and generates a data structure that represents the correlation between the condition and the degree to which the airway is open. This system can allow a sleep-apnea-treatment system to operate in a closed-loop mode, i.e., to monitor a level of sleep apnea in a subject by monitoring the correlated condition, and to treat the subject in a manner that the treatment system deems appropriate for the level of sleep apnea that the treatment system determines that the subject is experiencing.
