FOREHEAD AND NOSE BRIDGE PAD FOR CPAP INTERFACE
A pad is attachable to the forehead part of a CPAP face mask with pockets sewn into the body of the pad. The pad protects the forehead of the wearer and the nose bridge by a flap of material that fits between the seal of the mask and the wearer's nose bridge distributing the pressure from the mask seal. Persons with sleep apnea rely on CPAP therapy to prevent the obstruction in order to continue to breathe while sleeping. The CPAP masks appear medical and strange, especially to a new user of the device. By making the CPAP mask more comfortable with soft padding and also preventing marks and sores, it is more likely that the person will continue their therapy and improve their health. The invention is designed to be colorful, soft and comforting to help people with sleep apnea continue to get the necessary therapy.
This is a continuation of pending U.S. patent application Ser. No. 12/288,271 filed on Oct. 17, 2008, which claims the benefit of U.S. Provisional Patent Application No. 60/999,199, filed Oct. 17, 2007, the disclosures of which are incorporated herein by reference.

FIELD OF THE INVENTIONThis invention relates generally to the field of respiration, or breathing and/or ventilation masks. In particular, the invention relates to the forehead portion and seal of masks used in the treatment of sleep apnea.
BACKGROUND Prior ArtObstructive sleep apnea syndrome (commonly referred to as obstructive sleep apnea, OSA, and/or sleep apnea) is a medical condition that has as one symptom repeated prolonged episodes of cessation of breathing throughout the night. This is generally a condition in which a person's airway becomes blocked or restricted due to the over-relaxation of the muscles and tissues in the throat during sleep. A restrictive air supply impairs the oxygen flow to the lungs and, in turn, to the brain.
An individual with OSA can stop breathing, or suffer an apnea, for many times (typically from 10 to 30 times an hour) each night. The apneas are generally followed by sudden reflexive attempts to breathe. As a result, the individual suffering from OSA experiences fragmented sleep. Such non-refreshing sleep results in daytime drowsiness, headaches, weight gain, limited attention span, memory loss, lethargy, inability to maintain concentration and/or depression. OSA has also been linked to increased hypertension and greater risk of stroke, heart disease, and diabetes if left untreated. Untreated sleep apnea is also a leading cause of automobile accidents.
Effective treatment requires the airway to remain open during sleep. Modern respiratory therapy utilizes a “continuous positive airway pressure” (CPAP) machine and a ventilation interface during sleep in order to keep the airways open. A variety of CPAP machines can provide this treatment. BiPAP and VPAP are two specialized examples of CPAP machines that vary the pressure received based on the patient's breathing patterns. All positive airway pressure machines use an interface to deliver ambient air, under pressure, to the patient's airway which effectively forms a splint for the trachea. This interface usually consists of a nasal mask, full face mask (covering both the nose and mouth), or nasal pillows held onto the patient's face with straps, or headgear, and connected to the CPAP machine by way of an air hose. The nasal mask and full face mask employ a forehead pad that rests against the patient's forehead to stabilize the mask and to position the mask seal over the nose.
No matter what type of OSA interface is used, holding it in place over the nose and/or mouth is difficult, due to the air pressure blowing into it. The interface must be held in place securely to prevent air from escaping around the seal. The structure of the interface also must be rigid, and at the same time, soft against the wearer's skin. The mask seal against the bridge of the nose can cause pressure ulcers or bruising. When this is unresolved, it can be a major deterrent for the user to continue CPAP therapy.
Another difficulty results in the psychological aspects of the treatment. The CPAP and mask must be used anytime the person sleeps, including naps, for the duration of the patient's life in order to be effective against the long-lasting dangers of OSA. The mask and headgear is unnatural, cumbersome, medical, uncomfortable as well as unattractive on the face. CPAP treatment has even been the cause of personal relationships being destroyed. The hospital look of the mask during use, and the marks remaining on the face after use are a continual reminder of the patient's medical condition.
As a result of the varieties of difficulties and discomfort, some patients remove their masks in the night, at times not having realized that they have done so. Some patients choose to discontinue treatment for OSA because of the many difficulties associated with adjusting to the CPAP masks and nightly treatment. Without treatment compliance, OSA progressively becomes more severe as a person ages.
Durable Medical Equipment Suppliers (DME) have limited style choices available in masks and CPAP machines for the patients. Most of the masks and headgear are very similar in appearance and structure. Most patients have little knowledge about OSA when they are diagnosed and know very little about the treatment options. The patients are further handicapped due to the very nature of the disorder, and cannot think as clearly before as after receiving proper treatment, so are often given the mask and machine the DME selects for them. Having little input in the choice of equipment can negatively affect the dedication the patient has toward the treatment, especially considering the variety of challenges it presents and the extended time required to feel the benefits of the therapy, often taking a month or longer.
The invention of a colorful, very soft, forehead and nose bridge protection alleviates parts of the problems with OSA therapy listed above and helps patients remain compliant with their treatment. Compliant treatment allows the patients to experience a much greater quality and length of life.
In the related art, numerous attempts at treatment of OSA have been made. These attempts have included new masks and headgear designs; some have included designs to reduce the amount of contact area against the skin. Although the present style of masks include a forehead part, they do not address adequately the marks and bruising caused by the forehead part as well as the seal where it contacts the patient's nose bridge. A search of the prior art did not disclose any patents that read directly on the claims of the invention herein disclosed, however, the following patents were considered relevant:
While there are devices that provide treatment options for OSA, these do not disclose a successful padding solution for the CPAP interfaces. In this respect, the nasal headgear padding described herein departs from any present designs in providing comfort, physically and mentally, and style. Compliancy improves dramatically when the patient has comfortable options for the treatment of OSA.
The present invention, (Forehead and Nose Bridge Pad for CPAP Interface) discloses a padding which covers the CPAP forehead pad on the mask adjacent to the face. It also includes padding to prevent pressure ulcers on the nose bridge area. This extremely soft pad protects the wearer's forehead and bridge of the nose from any irritation caused by the presence of the interface. The present invention also protects the facial skin from any allergic reaction to the materials of the forehead part of the mask by forming a physical barrier. The material of the present invention is such that it promotes air circulation under the forehead pad controlling moisture build up and discomfort. The present invention provides distribution of the pressure applied by the mask to the skin in the areas of the forehead as well as the area of the bridge of the nose. By padding the edge of the forehead pad of the mask, the present invention prevents lasting indentions from forming on the forehead, and the flap portion prevents bruising and sores on the nose bridge. The softness of the present invention is comparable to a very soft blanket against the forehead and nose bridge adding physical as well as psychological comfort to the treatment of OSA. Soft comfortable padding increases the ease of falling to sleep and staying asleep.
The present invention (Forehead and Nose Bridge Pad for CPAP Interface) discloses that padding the forehead and nose bridge and preventing facial marks and sores allow the wearer of the CPAP mask to only think about the treatment of OSA at night when going to bed. It allows the medical nature of the disorder to be a private matter instead of having to explain the marks or sores on the face left behind by the interface at night. Psychological benefits include a more positive self image, and improve social interaction. The present invention improves the outward medical appearance of the headgear by being colorful and very soft as well as personalized. It also allows individual style for each person by being available in many colors. The present invention can match other clothing worn to bed and feel more like an accessory.
The present invention can be changed often when the wearer wants a different style or color on the headgear.
The present invention (Forehead and Nose Bridge Pad for CPAP Interface) discloses that by adding padding to certain non-adjusting forehead parts, it effectively reduces the pressure of the mask seal on the wearer's face.
Prior art treatment options for OSA do not adequately address a successful padding solution for the headgear of CPAP interfaces. The Forehead and Nose Bridge Pad for CPAP Interface padding described herein deviates from any prior art in providing improvements in the way of comfortable options for OSA patients and thereby improves compliancy. Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
SUMMARYIn accordance with the present invention, Forehead and Nose Bridge Pad for CPAP Interface, the padding for CPAP interfaces comprise a resilient, sufficiently bulky fabric formed in a fashion to provide secure padding protection for the skin on the forehead and nose bridge of a sleep apnea patient receiving CPAP therapy. This padding invention increases comfort, prevents marks and bruising on the forehead and nose bridge for patients using a CPAP mask. By offering a colorful addition to the CPAP mask, this also can add some personalization to the interface. Any improvement to OSA therapy can help patients remain compliant with their therapy which ultimately results in improved health.
