The instant disclosure is related to a mechanism to insure an unobstructed airway during sleep on the back position and specifically a cervical assist pillow.
The majority of the adult population snores at various intensities during sleep, those who snore louder may have obstructive sleep apnea (OSA) due to blockage of airflow from the collapsing of the upper airway. Based on the diagnostic criteria of apnea-hypopnea index (AHI)≥5 times/hour per the American Academy of Sleep Medicine (AASM) in 2012, an estimated 936 million people worldwide between the ages of 30 and 69 have OSA; among them an estimated 425 million people worldwide meet the requirement for moderate OSA with AHI≥15 times/hour that are usually recommended for treatment as it increases risk of cardiovascular comorbidities if left untreated.
At present, there is no easy treatment option for OSA. The most widely relied upon treatment method is to use continuous positive airway pressure treatment (CPAP) during sleep. Alternative treatment options include oral appliances, surgery and/or weight loss. CPAP and oral appliance treatment are uncomfortable, inconvenient, and have only a 50-60% compliance rate; especially when the CPAP pressure is high. When the CPAP pressure is high the mask is prone to air leaks and discomfort. There are multiple limitations related to a surgical treatment option, which include high cost, surgical risks and a relatively low effective cure rate of about 60%.
What is sought is another method of providing an unobstructed airway during sleep that does not rely upon a CPAP or surgery.
An example cervical assist pillow, comprising at least one of, a lower back support portion having a wedge therein to accept a user's upper back and shoulders, an upper neck support portion adjacent the lower back support portion, the upper neck support portion having an extended height to support the users neck proximate a user's head and having a height to elevate the user's neck at a cervicomental angle between approximately 100 and 120 degree, a head support portion adjacent the upper neck support portion and having a concavity to accept the back of the user's head and a waist belt coupled to the lower back support portion at a first end and detachably couple-able to a user's midsection to prevent slippage from under the user's head and neck.
Another example cervical assist pillow insert, comprising at least one of, a lower rail portion connectable to a pillow at a lower end and a bulbous portion connected to the lower rail portion and having a combined height to elevate a user's neck at a cervicomental angle between approximately 100 and 120 degree.

The embodiments listed below are written only to illustrate the applications of this apparatus and method, not to limit the scope. The equivalent form of modifications towards this apparatus and method shall be categorized as within the scope the claims.
Certain terms are used throughout the following description and claims to refer to particular system components. As one skilled in the art will appreciate, different companies may refer to a component and/or method by different names. This document does not intend to distinguish between components and/or methods that differ in name but not in function.
In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus may be interpreted to mean “including, but not limited to . . . .” Also, the term “couple” or “couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device that connection may be through a direct connection or through an indirect connection via other devices and connections.
Snoring and OSA tend to be worse when people sleep on their back as airway tends to collapse more at this position, in fact there are subgroup of patients who have OSA only when they sleep on the back position. During cardiopulmonary resuscitation (CPR), the head is tilted to a chin-lit position to keep the upper airway passage open. Based on this observation, the cervical assist pillow supports of the neck and tilt of the head so that users can maintain a head-tilt chin-lift position during sleep to keep their upper airway open.
The device may keep the upper airway open more effectively, which may relieve snoring and obstructive sleep apnea when lying on the back position. If CPAP therapy is used simultaneously it can also help reduce the CPAP pressure requirement reduce discomfort and air leak at CPAP mask by avoiding CPAP mask compressing on the pillow so that CPAP treatment compliance can be improved.
The cervical assist pillow may more effectively support the neck and tilt of the head so that users may maintain head-tilt chin-lift position while sleeping on their back to keep their upper airway patent. The cervical assist pillow may be made from polyurethane or latex using foaming technology.
The cervical assist pillow waist belt at the pillowcase may prevent the head from sliding down toward the feet, and ensure the head remaining in tilt position while sits in the concave area of the pillow, so the upper airway would remain open when lying on the back position.
The cervical assist pillow insert may adjust the firmness and height of the pillow to provide comfortable and effective support for the neck based on individual preference. It may also be filled with incents, herbs or other material that may assist in helping a user sleep better.
Those of skill in the art would appreciate that the various illustrative blocks, modules, elements, components, methods, and algorithms described herein may be implemented as electronic hardware, computer software, or combinations of both. To illustrate this interchangeability of hardware and software, various illustrative blocks, modules, elements, components, methods, and algorithms have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application. Various components and blocks may be arranged differently (e.g., arranged in a different order, or partitioned in a different way) all without departing from the scope of the subject technology.
The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. The previous description provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects.
