It is known that some individuals suffer from mild to severe sleep disorders. Some individuals merely have difficulty falling asleep, or perhaps staying asleep, while others have difficulty maintaining consistent, healthy breathing patterns. Individuals who suffer from sleep apnea are known to regularly stop breathing for 10 seconds or more, and in some cases, the apnea can last for minutes. This can cause a variety of problems for the individual, including drowsiness, irritability, cardiovascular deficiencies and diseases, and cognitive deficiencies and diseases.
Additionally, it is known that sleep apnea can be difficult to initially detect, and can also be difficult to effectively treat. Frequently, individuals suffering from sleep apnea are unaware of experiencing apneas throughout the night, and are unaware of what is causing their drowsiness the next day. Once a formal sleep study is conducted, diagnosis of sleep apnea can be made.
Treatments after diagnosis often include lifestyle changes, medication, and behavioral therapy. Additionally, in some cases, a continuous positive air pressure (CPAP) machine can be used and a splint employed in order to facilitate and encourage healthier breathing patterns during sleep. Another common treatment method for sleep apnea is oral appliance therapy (OAT), which uses a mandibular advancement device (MAD) to hold the jaw in a position that precludes airway collapse.
These approaches which involve the use of a CPAP machine or MAD are designed to be used by themselves without the need of additional components or devices used in conjunction with them.
There is a need for a device capable of externally maintaining the lips and/or jaw of the face of a user or patient, such as a patient diagnosed with a sleep disorder, in a relaxed, closed posture, in order to facilitate respiration through the nasal passages and aid in the treatment and prevention of sleep apnea or related sleeping disorders. Such a device would augment the efficiency of some of these treatments, particularly the CPAP and MAD treatments, by correcting the deficiencies in the previous approaches.
The present disclosure relates to a combination of a sleep strip (e.g., face sleep strip) designed to be worn by a person during sleep and a device for treating sleep-disordered breathing (SDB). More specifically, the present disclosure relates to a combination of a sleep strip configured to cover a mouth and lips of a user or patient and a continuous positive airway pressure device configured to continuously blow pressurized air into the nasal passages of the user or patient or a mandibular advancement device configured to hold a jaw of the user or patient in position. The object of the present disclosure is to ensure healthy breathing patterns in the user or patient, specifically by preventing breathing patterns that induce sleep apneas or snoring and by ensuring that the user or patient's airway does not collapse, thus ensuring the user or patient can breathe through the nasal passages.
The following presents a general summary of aspects of the present disclosure in order to provide a basic understanding of the disclosure. This summary is not an extensive overview of the disclosure and is not intended to identify key or critical elements of the present disclosure or to delineate the scope of the present disclosure. The following summary merely presents some concepts of the present disclosure in a general form as a prelude to the more detailed description provided below.
The present disclosure relates to a combination of a sleep strip configured to hold a user or patient's mouth in a naturally closed position such that the tongue and jaw of the user or patient will not relax during sleep and thereby cause pauses in breathing and a CPAP machine or MAD. The sleep strip includes a hypoallergenic adhesive affixed to a paper-thin, perforated silicone or cloth (e.g., polyester) mesh layer such that the sleep strip is securely and temporarily affixed to the face of a user or patient (e.g., the cheeks, lips, and/or jaw of the user or patient). The sleep strip according to the present disclosure is configured to hold the lips of the user or patient closed such that the user or patient can breathe through the nasal passages and nostrils while aided by the CPAP machine or MAD. A sleep “mask” is disclosed in U.S. Pat. Nos. 8,991,399 and in 9,795,175, the disclosures of which are incorporated herein in their entirety by reference.
The sleep strip includes a first layer having an opening configured to provide an alternate channel for oral respiration during use of the sleep strip in an event that one or more nasal passages of the user or patient become blocked, forcing the user or patient to breathe through the mouth. The opening is disposed on a location on the first layer and is configured to lie over or just above the mouth of the user or patient during use of the sleep strip. The sleep strip also includes a permeable mesh layer, which includes a mesh disposed over the first layer such that the permeable mesh layer covers at least a portion of a surface of the first layer and covers the opening in the first layer.
The sleep strip is configured to conform to the shape of the user or patient's face, and provide a semi-secure seal over the mouth of the user or patient during use. While the seal need not be completely air-tight, any restriction over the mouth of a user or patient during sleep will help to curtail his or her use of the mouth to breathe.
When the sleep strip is properly positioned and affixed to the face of the user or patient, the user or patient's respiration is channeled, and therefore encouraged to flow through the nasal passages of the user or patient rather than through the mouth. Through this method of respiration, it is less likely for the user or patient to suffer from a sleep disorder such as sleep apnea.
In some embodiments of the present disclosure, a method for treating sleep-disordered breathing in a patient includes prior to sleeping, placing a sleep strip on a face of the patient, the sleep strip being configured to maintain lips and/or a jaw of the patient in a closed posture, and the sleep strip including a first layer comprising an adhesive configured to attach the sleep strip to the face of a patient, the first layer having an opening extending therethrough, the opening being located above the lips of the patient, and a mesh layer covering at least the opening of the first layer, the mesh layer being configured to allow air to flow therethrough; and disposing a device configured to facilitate stable breathing patterns on a face or in a mouth of the patient.
According to one aspect, the method is for treating sleep apnea, and the device is a continuous positive air pressure machine.

In some embodiments, a method for treating sleep apnea in a patient is disclosed. The method includes the steps of placing, prior to sleeping, a first device including a sleep strip on a face of a patient diagnosed with sleep apnea; disposing a second device configured to treat sleep apnea in connection with the patient; and maintaining stable breathing patterns in the patient.
In some embodiments, a method for treating snoring in a patient is disclosed. The method includes the steps of placing, prior to sleeping, a first device including a sleep strip on a face of a patient diagnosed with snoring; disposing a second device configured to treat snoring in connection with the patient; and maintaining stable breathing patterns in the patient.
The systems and methods according to the present disclosure are capable of embodiments in many different forms, and there are shown in the drawings, and will herein be described in detail, certain embodiments with the understanding that the present disclosure is to be considered exemplary of the principles of the invention and is not intended to limit the broad aspects of the invention to the embodiments illustrated and described.
Referring generally to the FIGURES, the present disclosure relates to a system, such as system 100 shown in
As shown in
A MAD 16 may be formed of a variety of materials and configured to be disposed in variation locations in the mouth of a user or patient. For example, a PM Positioner™ is formed of an acrylic material and has an adjustment mechanism disposed on a cheek side of the device near a user or patient's molars when the device is worn by the user or patient. As another example, the SomnoDent® SUAD™ is formed of an acrylic material reinforced by a metal framework and has an adjustment mechanism which includes two elastic bands and which keeps the jaw of the user or patient from falling open during sleep. As another example, a SomnoDent® MAS device is formed of an acrylic material and has a recessed screw mechanism on each side of an upper part and ball clasps which hold the device in position. As another example, an EMA® (Elastic Mandibular Advancement) device is formed of a plastic material and has an upper part and a lower part connected to the upper part by rubber straps on sides of the device; by using differently sized straps, the device may be positioned differently while in use. As another example, a TAP® (Thornton Adjustable Positioner) is a device formed of a nickel-free, allergen-free material reinforced by a cobalt-chromium hardware and has a hook and socket mechanism which holds an upper tray and a lower tray together; the device's position is adjustable. As another example, a Herbst Appliance is formed of acrylic, thermal active, and soft materials and has a post and sleeve mechanism to advance a jaw of a user or patient and a ball and hook mechanism such that a vertical opening degree is adjustable.
However, a MAD 16 is ineffective if a tongue 13 of a user or patient 10 does not remain sealed to the palate. Because it is often difficult for the user or patient 10 to naturally close the mouth over a MAD 16, users or patients often experience lip incompetence. Lip incompetence leads to an oral respiratory breathing pattern that results in a loss of a seal between the tongue 13 and palate of the user or patient. Once the seal is lost, the tongue 13 falls back into the airway; the blocked airway results in snoring and sleep apnea, as is shown in

There are three different approaches to a CPAP machine. First, a nasal mask, such as nasal mask CPAP machine 21 (shown in
Second, a nasal pillow, such as nasal pillow CPAP machine 22 (shown in
Third, a full face mask, such as full face mask CPAP machine 23 (shown in
When a user or patient 10 is using a CPAP machine, such as the nasal mask 21, the nasal pillow 22, or the full face mask 23, the user or patient 10 is aware when the CPAP machine is not keeping the user or patient's airway patent because leakage of air from the nose or mouth of the user or patient tends to wake the user or patient. Specifically, for nasal mask users, opening the mouth causes pressurized air to enter the nose and exit the mouth of the user or patient. A noticeable turbulence will wake the user or patient 10 and cause the user or patient 10 to close the mouth to continue receiving the pressurized air in the airway. Alternatively, the user or patient 10 may remove the nasal mask 21, the nasal pillow 22, or the full face mask 23 entirely, rendering treatment by a CPAP machine moot.

A front surface 42 of the first layer 41 is configured to adhere to a face of a user or patient such that the sleep strip 40 fits comfortably on the lips, mouth, and/or jaws of a user or patient without placing an external stress on the user or patient's mouth or jaw. A rear surface 44 of the first layer 41 is configured to adhere to a mesh layer 45 (described in more detail below). The sleep strip 40 is configured to ensure that a user or patient does not rely fully upon oral respiration during sleep, as oral respiration predisposes the user or patient to snoring and/or apnea.
The front surface 42 of the first layer 41 of the sleep strip 40 is equipped with an adhesive substance which is sufficiently strong to bind the sleep strip 40 temporarily to skin, yet does not irritate the skin or leave a sticky residue on the skin. According to one aspect, the adhesive covers an entire surface of the front surface 42, as shown in
The first layer 41 has at least one opening (e.g., permeation) 43 configured to allow air to pass through the sleep strip 40. The opening 43 is also configured to prevent a user or patient from engaging in inefficient oral respiratory patterns. However, it is desirable that a size and/or number of the opening 43 not be so high as to allow a user or patient to subconsciously engage in oral respiration. In some aspects, the opening 43 is positioned on the sleep strip 40 in a configuration such that when the sleep strip is worn by the user or patient, the opening 43 lies directly above and/or around the lips of the user or patient. In some aspects, the opening 43 is positioned at a central position on the first layer 41.
Entry and exit points of a nasal cavity (i.e., the two nostrils) of a patient generally have an area of 350 square millimeters, and humans generally use one nostril when breathing nasally. The relatively small size of the two nostrils assists in optimizing a CO2—O2 exchange, as air is recycled, allowing more time to extract maximum O2. On the other hand, the entry and exit point of the oral cavity (i.e., the mouth) is significantly larger. When a person breathes orally, the person may exacerbate airway collapsibility by exhaling all of the air in the respiratory airway upon exhalation, decreasing the amount of O2 retained.
The opening 43 allows for oral respiration if nasal respiration becomes impossible. The opening 43 is configured to conform to a user or patient's nostril area, nasal cavity, and/or oral cavity. The opening 43 may mimic the nostrils, with the mesh layer 45 acting as a filter, and the small size of the opening 43 functioning as a check valve to preclude full oral exhalation, and thereby improve CO2—O2 exchange. The opening 43 is purposely small to encourage nasal respiration. In the case of full nasal blockage and difficulty with oral respiration, a user or patient or another person may remove the sleep strip from the face of the user or patient. This removal ability reduces or prevents the possibility of hypercapnia, which occurs when there are excessive levels of CO2 in the blood.
The opening 43 exists to provide a restricted channel for air to pass through. The opening 43 has a cross-sectional area, according to one example, no larger than about 125 square millimeters and may have any suitable geometry. For example, the opening 43 may have a square cross-sectional shape. As an additional example, the opening 43 may have a rectangular cross-sectional shape. As another example, the opening 43 may have a circular cross-sectional shape. As yet another example, the opening 43 may have a somewhat elliptical cross-sectional shape as shown in
According to one example, the first layer 41 of the sleep strip 40 is covered with an adhesive backing, such as a piece of waxed paper, in order to keep the first layer 41 (for example, the adhesive on the front surface 42 of the first layer 41) clean and sterile until time of use. Similarly, in some exemplary embodiments, such as those sized for smaller mouths or faces, the adhesive of the sleep strip 40 may also encompass or come into contact with the opening 43 or come very near to the site of the opening 43 of the sleep strip 40. The adhesive of the first layer 41 is also configured to leave little to no sticky residue behind, and is capable of holding a stable position on the face of the user or patient that endures for the duration of the sleep session.

It is envisioned that the sleep strip 40 is capable of remaining securely affixed to or over the lips and jaw of the user or patient for the duration of the sleep session due to the strength and rigidity of the material used to form the mesh layer 45, as well as due to the efficacy of the first layer 41 of the sleep strip 40. It should be noted that the first layer 41 and the mesh layer 45 of the sleep strip 40 are hypoallergenic and may be kept in a sterile container until use. The sleep strip 40 may also be kept in a sterile polypropylene envelope, similar to a conventional adhesive bandage, in order to ensure dirt and other contaminants do not compromise the sterility and/or cleanliness of the sleep strip 40.
Alternate aspects of the sleep strip 40 according to the present disclosure may include variations on the size of the opening 43. For example, for users or patients with a large lung capacity, the standard size of the opening 43 of the sleep strip 40 may be too small, which could cause the user or patient to faint from a lack of oxygen if the user or patient's nasal passages become blocked during the use of the sleep strip. As such, according to some aspects, the sleep strip 40 includes an opening 43 that has a larger diameter, or if the opening 43 is a mesh screen, the mesh screen may be larger or equipped with additional small holes to permit slightly greater air flow.
Similarly, the sleep strip 40 may be available in a variety of sizes in order to accommodate all shapes and sizes of faces. While it is envisioned that a ‘one-size-fits-all’ size of the sleep strip 40 will likely function appropriately for most individuals, larger sizes may be needed for individuals with irregularly shaped or sized mouths or other facial features.
In the event that the user or patient has a full face beard, the adhesive of the sleep strip 40 will be less effective than when placed on a user or patient without facial hair. As such, it is envisioned that an alternate embodiment of the sleep strip 40 includes at least one elastic band (not shown) which may facilitate the stable placement of the sleep strip 40 onto the user or patient's face. It is envisioned that the elastic band would be affixed to the sides of the sleep strip 40 and be capable of retaining the sleep strip 40 in position on the mouth and/or lips of the user or patient by extending the elastic band around the user or patient's ears or the back of the user or patient's head. An adhesive may still be employed in this alternate embodiment of the sleep strip 40; however, it is understood that facial hair would likely infringe on the adhesive's capacity to remain affixed to the face, mouth, and/or lips of the user or patient for the duration of the sleep session. An alternate embodiment of the sleep strip 40 may be a smaller version of the sleep strip 40. It is envisioned that the smaller version would interact only with the lips of the user or patient, to ensure that no facial hair would infringe on the adhesive.

Clinical trials using the system 100 including a sleep strip 40 and a second device (such as a CPAP machine or a MAD) were carried out to assess the effectiveness of the system 100 at treating and/or preventing sleep disorders such as sleep apnea and/or snoring. The clinical trials were designed to test the hypothesis that the system 100 improves sleep apnea severity, measured by a apnea-hypopnea index (AHI), and reduces the severity of pharyngeal collapse relative to treatment of patients that does not include use of the sleep strip 40 disclosed herein (for example, no treatment for sleep disorders or treatment using only a CPAP machine or MAD). The clinical trials included 36 subjects (including expected trial dropout subjects). Subjects were determined based on the following inclusion and exclusion criteria. The inclusion criteria included: age of a subject ranged between 21 to 70 years; the subject had an AHI of between 10 to 50 events per hour; the subject had a body-mass index of less than 38 Kg/m2; and the subject had a neck circumference of less than 20 inches for men and less than 17 inches for women. The exclusion criteria included: any medication taken by a potential subject which is known to influence breathing, sleep/arousal or muscle physiology; concurrent sleep disorders (such as insomnia, narcolepsy, central sleep apnea, and parasomnia) in a potential subject; inability of a potential subject to sleep supine; and failure of a potential subject to comfortably breathe nasally for a period of 1 to 2 minutes.
The clinical trials included a regime of four home sleep testing sessions conducted over the course of one month and determined in random order for each test subject: 1) a sleep session with no treatment; 2) a sleep session using only an oral appliance (such as a CPAP machine or MAD); 3) a sleep session using an oral appliance and a sleep strip; and 4) a sleep session using only a sleep strip. The test subjects were asked to maintain a sleep log. Additionally, sensors were attached to the bodies of the subjects for the duration of a sleep session. The sensors recorded electroencephalographic signals, electrocardiographic signals, nasal pressure, oxygen saturation, snoring decibel levels, and chest and abdominal movements. According to the clinical trials, the use of system 100 may result in a decrease of between 20% and 100% in the AHI. According to the clinical trial design, any decrease in AHI of 10 events per hour or more is considered to be clinically important.
In some embodiments, a method 1100, illustrated in
In some aspects, the method 1100 includes a first step of diagnosing a patient who suffers from a sleep disorder (e.g., sleep apnea). For example, the first step is diagnosing a patient who suffers from OSA because of a blockage in the patient's airways. OSA causes a patient to stop breathing for a short period of time, and OSA can occur periodically during a patient's sleep session. OSA is more common in men, adults over the age of 65, patients who are overweight, and patients who have jaw problems (e.g., micrognathia, retrognathia, etc.), though in some cases, other patients (e.g., children, women, etc.) also suffer from OSA. There are various symptoms of OSA which are used by a health care provider to make an OSA diagnosis. Some symptoms are evident during a patient's sleep, such as unusually loud snoring (both intermittent and continuous), gasping or choking, pauses in breathing patterns, abnormally sudden body movements, restless tossing and turning, and frequent awakenings. Some symptoms are evident during a patient's waking periods, such as feelings of sleep deprivation, headaches shortly after awakening, dry or sore throat after awakening, fatigue during the day, drowsiness during the day, mood swings, memory loss, and inability to concentrate.
In some aspects, diagnosing a patient who suffers from a sleep disorder (e.g., sleep apnea) is conducted by a polysomnography (e.g., a monitored overnight sleep session at a sleep center).
In some aspects, the second device is a continuous positive air pressure machine.
In some aspects, the second device is a mandibular advancement device.
In some aspects, the method 1100 also includes positioning the sleep strip such that an opening in a first layer of the sleep strip lies directly above a mouth of the patient.
In some aspects, the method 1100 also includes affixing the sleep strip to an upper lip and a lower lip of the patient using an adhesive.
In some aspects, the method 1100 also includes covering a mouth of the patient with the sleep strip.
In some aspects, the method 1100 also includes forming a semi-secure seal over the mouth of the patient with the sleep strip.
In some aspects, the step 1103 of the method 1100 includes reducing an incidence of the sleep disorder (such as sleep apnea) in the patient below some predetermined threshold relative to an incidence of sleep apnea in the patient prior to any treatment for sleep apnea. In some aspects, the method 1100 may also include reducing an incidence of sleep apnea in the patient relative to treatment without using a sleep strip as disclosed herein. As one example, the method 1100 may include reducing an incidence of sleep apnea in a patient from between 20% and 100%. As a specific example, the method 1200 may also include reducing an incidence of sleep apnea in the patient by between 50% and 90% relative to the incidence of sleep apnea in the patient prior to treatment using the sleep strip disclosed herein. As a more specific example, the method 1100 may also include reducing an incidence in sleep apnea in a patient by 50% relative to treatment without using the sleep strip. As an additional specific example, the method 1100 may also include reducing an incidence in a sleep disorder (e.g., OSA) in a patient to a level of clinical insignificance.
In some embodiments, a method 1200, illustrated in
In some aspects, the method 1200 for treating snoring includes a first step of diagnosing a patient who suffers from snoring. For example, the first step includes diagnosing a patient who suffers from vibrations in tissues of a throat of the patient when air flows through an airway of the patient. The vibration can result in a loud, raspy noise which may awaken the patient from sleep, awaken others in the patient's surrounding environment, or both. Snoring can be difficult for the patient to detect without assistance from another person (e.g., a health care provider, a bed partner, etc.). Snoring is more common in patients who are overweight, smoke, are back-sleepers, or suffer from congestion, though snoring can occur in other patients as well.
In some aspects, the second device is a continuous positive air pressure machine.
In some aspects, the second device is a mandibular advancement device.
In some aspects, the method 1200 also includes positioning the sleep strip such that an opening in a first layer of the sleep strip lies directly above a mouth of the patient.
In some aspects, the method 1200 also includes affixing the sleep strip to an upper lip and a lower lip of the patient with an adhesive.
In some aspects, the method 1200 also includes covering a mouth of the patient with the sleep strip.
In some aspects, the method 1200 also includes forming a semi-secure seal over the mouth of the patient with the sleep strip.
In some aspects, the step 1203 of the method 1200 includes reducing an incidence of snoring in the patient to a predetermined level relative to an incidence of snoring in the patient prior to any treatment for snoring. In some aspects, reducing an incidence of snoring includes reducing a frequency of snores, a decibel level of snores, or both. In some aspects, the method 1200 also includes reducing an incidence of snoring in the patient relative to treatment without using a sleep strip as disclosed herein. As one example, the method 1200 may include reducing an incidence of snoring in a patient from between 20% and 100%. As a specific example, the method 1200 may also include reducing an incidence of snoring in the patient by between 50% and 90% relative to the incidence of snoring in the patient prior to treatment using the sleep strip disclosed herein. In some aspects, the method 1200 may also include reducing a decibel level of snores of the patient relative to treatment without using a sleep strip as disclosed herein. For example, the method 1200 may also include reducing the decibel level of snores of the patient by between 50% and 90% relative to the incidence of snoring in the patient prior to treatment using the sleep strip disclosed herein.
