Benefits of technology

The respiratory device described in the patent is a device that can be placed in a person's nasal or mouth to help them breathe. It has a part that slows down the airflow and a mechanism for being secured in place. This device can be easily applied or removed by the user and does not need to be done by a physician. The device can also be adjusted to provide different levels of pressure during breathing. This allows the person to have a comfortable breath in and out, while still getting the proper respiratory support.

Problems solved by technology

The heart can then no longer adequately pump blood to the body including the lungs.
This may lead to exercise intolerance, or may cause fluid retention with subsequent shortness of breath or swelling of the feet.
Morbidity and mortality in patients with heart failure is high.
Despite the prevalence of hypertension and its associated complications, control of the disease is far from adequate.
This failure reflects the inherent problem of maintaining long-term therapy for a usually asymptomatic condition, particularly when the therapy may interfere with the patient's quality of life, and when the immediate benefits of the therapy are not be obvious to the patient.
This makes it difficult for the air to move in and out of the airways, leading to respiratory distress.
This narrowing or obstruction can lead to coughing, wheezing, shortness of breath, and / or chest tightness.
In some cases, asthma may be life threatening.
In all of these diseases, current medical and surgical therapies are not completely effective, and there is considerable room for improvement.
However, pursed-lip breathing requires conscious effort.
Thus, the patient cannot breathe through pursed-lips while sleeping.
As a result, the patient can still become hypoxic at night and may develop pulmonary hypertension and other sequelae as a result.
This interferes with his performing of other activities because the patient must pay attention to maintaining pursed-lip breathing.
However, most patients experience difficulty adapting to nocturnal NPPV, leading to poor compliance.
Mask discomfort is a very common problem for patients new to NPPV, because of the high pressures on the nose, mouth, and face, and because of uncomfortably tight straps.
Nasal congestion and dryness are also common complaints that may vary by season.
The nasal bridge can become red or ulcerated due to excessive mask tension.
Eye irritation and acne can also result.
Finally, air leakage through the mouth is also very common in nasal NPPV patients, potentially leading to sleep arousals.
In contrast, inspiratory support is not believed to offer clinical benefits in many patients.
However, CPAP devices (including modified devices such as “C-FLEX” devices manufactured by Respironics) are expensive, uncomfortable and cumbersome, leading to limited application and patient compliance.

[0261]A. Removable Application in the Oral Cavity

[0262]A respiratory device adapted for use in the oral cavity (e.g., any of the devices shown in FIGS. 1-3) may be placed into a subject's mouth by medical personnel or by the subject. The respiratory device may be secured in place by the subject's teeth, gums, tongue, lips, palate or shape of the oral cavity or surrounding anatomy including the jaw, nose, chin, or skin. The respiratory device may also (or alternatively) be secured by use of an adhesive, a securing strap, or by other holdfast. The use of an adhesive may further improve the seal between the device and the oral cavity. The device may be worn during the night or day, while the patient is awake or sleeping. In some cases, the device may be worn continuously for extended periods of time (e.g., minutes, hours, days). These devices are meant to provide benefits to subjects suffering ...

Abstract

Devices for altering the flow of air in a respiratory cavity such as the nostrils of the nose. These methods and devices may be useful for affecting a physiologic benefit in patients suffering from a variety of medical disorders, including snoring and sleep apnea. The devices are typically removable devices that may be placed in both nostrils to increase resistance to airflow within the respiratory cavity. Resistance to expiration may be selectively increased relative to inspiration. The nasal devices may also increases patency of the nares. Any of these devices may be configured to achieve positive end-expiratory pressure (PEEP) in a subject wearing the device.
