Definitions

  • the present disclosure relates primarily to the field of external devices fitted to the head of a human subj ect.
  • Sleep apnea is a serious breathing disorder characterized by repeated sequences of snoring, breathing difficulty, lack of breathing, waking enough to resume breathing and returning to sleep. Often, the sufferer is not consciously aware of the sleep disorder. Individuals suffering from sleep apnea usually experience symptoms characteristic of sleep deprivation, such as severe drowsiness, irritability, functional and mental limitations, etc. Sleep apnea sufferers are also at greater risk to develop hypertension, heart attack, and stroke. In addition, untreated sleep apnea may be responsible for poor performance in everyday activities, such as at work and school, motor vehicle crashes, as well as academic underachievement in children and adolescents.
  • OSA obstructive sleep apnea
  • CSA central sleep apnea
  • MSA Mixed sleep apnea
  • CPAP Continuous Positive Airway Pressure
  • OSA Continuous Positive Airway Pressure
  • CPAP has also been shown to be an effective treatment, for example, of patients suffering from Alzheimer's Disease with a sleep-related breathing disorder.
  • CPAP Improves Sleep In Patients With Alzheimer's Disease, Sleep-related Breathing Disorder, ScienceDaily, sciencedaily.com- /releases/2007/06/070611074214.htm).
  • CPAP decreases daytime sleepiness and lowers blood pressure during both the day and the night. Additionally, people with coronary artery disease who use CPAP for sleep apnea are less likely to have heart problems such as heart failure. Sleeping partners of individuals treated with CPAP may also enjoy improved sleep, at least in part due to control of the treated individual's breathing volume and restlessness-related motor activity.
  • CPAP may be used nightly, during sleep. CPAP therapy increases air pressure in the throat of the subject, so that the subject's airway does not collapse when the subject inhales.
  • the preferred CPAP apparatuses in common use presently comprise a mask covering the nose (Nasal Continuous Positive Airway Pressure: NCPAP); examples of alternative devices include those with breathing tubes inserted directly into the nasal passage, and full-face masks that cover the nose and mouth.
  • Embodiments include devices for use in the treatment of sleep apnea, and more particularly, OSA. It is understood that these embodiments are illustrative, and in no way limit the scope of the invention. These or other embodiments may be used in the treatment of other breathing disorders, in the comfortable attachment of external devices in a fixed position to the face or mouth of a human subject during sleep, in the delivery of assisted respiration to an adult or a neonate, in the attachment of orthodontic hardware to the face or mouth of a human subject, or in any context where a comfortable means of attaching an external device in a fixed position to the face of a subject is desired.
  • Embodiments include a device for receiving a human head comprising: at least one means for adjustably fitting the device to the human head, a chin portion capable of engaging a human chin, and a portion capable of engaging a continuous positive airway pressure system (CPAP) in an operative position on the head.

  • CPAP treatment is only effective if the subject of treatment wears the apparatus during sleep.
  • CPAP apparatuses, and devices associated therewith may cause, for example, acne or molding of the subject's hair into undesirable positions and are often not worn, or else removed, to avoid these undesirable results that may accompany CPAP treatment.
  • several troublesome side-effects of CPAP therapy limit its usefulness as an ameliorative treatment. Patients treated with CPAP may experience nightmares and excessive dreaming during early use, dry nose, nosebleeds, sore throat, nasal congestion, runny nose, sneezing, irritation of the eyes and the skin on the face, abdominal bloating, headaches, and/or leaks around the mask.
  • a CPAP apparatus may fail to provide a therapeutic benefit if the pressure seal between the CPAP apparatus interface and the face of the human subject is broken. Additionally, the effectiveness of CPAP using a nasal mask or nasal tubes is contingent upon the subject breathing exclusively through the nose. When a subject fitted with such a CPAP apparatus breathes through the mouth, the positive air pressure exerted by the device cannot act to prevent airway collapse.
  • a variety of techniques are employed to bias the subject's mouth to a closed position during sleep.
  • Such techniques include chinstrap devices and neck pillows. These additional measures further encumber the subject with uncomfortable external hardware while the subject desires sleep, and makes it increasingly difficult for the subject to obtain a restful position.
  • combinations of devices that exist in the art hold the CPAP apparatus in place through tension that is exerted through one or more straps of discrete diameter. The area of the subjects' head beneath these straps experiences that focused tension during the entire time the devices are used.
  • Periods of extended use such as during sleep, lead to side effects of this focused tension, for example, acne, abrasions, rashes, and the destruction of desired hair designs.

  • the tension holding the device against the head of a human subject is distributed essentially evenly across the top and back of the head of a human subject. Such distribution may allow a more secure fit than traditional CPAP headgear devices, without the acne, rashes, bruising, or hair-shaping that often accompanies use of a traditional device with discrete straps.
  • points of attachment for a CPAP interface and/or a chin strap portion are widely distributed across the surface of a device. Such distributions may allow individual wearers to fit a device comfortably and securely according to their individual facial anatomy.
  • CPAP apparatuses are often used at home for the treatment of sleep apnea, but are also useful more generally in the treatment of patients suffering from respiratory failure and neonates.
  • a CPAP apparatus includes a flow generator, a hose or tubing, and an interface.
