Headwear is adapted for use by a patient to position airway tubes of a nasal interface operatively connected to a positive airway pressure device. The headwear includes an elongated head strap for being worn around a head of the patient. Cooperating sets of front and rear tube holders are attached to the head strap, and are adapted for engaging and holding respective airway tubes of the nasal interface to retain the tubes in a desired position during use. The tube holders include at least one elastic strip extending along a longitudinal dimension of the head strap.

The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. A bleed port for release of exhaled air is defined through a conical vent projecting normally to the path of the incoming air flow, and continues through a nipple extending to the exterior of the air conduit. In one embodiment, a pair of nasal inserts are integral with a nasal cannula body, with bleed ports axially aligned with each insert. In another embodiment, each insert is independently connected to a separate, thin-walled, flexible supply line.

Disclosed herein are various methods, systems, an apparatuses for determining appropriate situations to treat conditions such as sleep apnea. At appropriate times, treatment can be applied such as through electrical stimulation to a person (e.g., an electrical stimulation of a person's genioglossus muscle in response to detecting that the person is undergoing an obstructive sleep apnea precursor event). In exemplary embodiments, a sensor such as a microphone and / or motion sensor can be used to provide a processor with data to facilitate a determination by the processor as to whether an electrical stimulus should be applied.

The invention provides a monitoring device controlled based on an intelligent mobile phone for preventing obstructive sleep sudden death. The monitoring device includes the intelligent mobile phone, an image detection and signal treatment device and an oximeter. The image detection and signal treatment device includes: an image recognition and signal treatment module based on Digital Signal Processor (DSP), an RGB camera shooting module, a storage module and a wireless module. The recognition and signal treatment module includes: a heart rate signal analysis module, a snore signal analysis module and a breathe frequency analysis module. The heart rate analysis module is respectively connected to the RGB camera shooting module and the storage module and measures the sleep heart rate, the breathe, and the snore in non-contact manner, measures the blood oxygen saturation through the oximeter, fits a function according to negative correlation of the blood oxygen saturation and sleep apnea time, thereby improving the veracity and effectiveness of the oximeter, systematically analyzing the signal variation to recognize the sleep condition and to prevent the sleep sudden death.

A device for treating a patient suffering from obstructive sleep apnea or snoring can include an expiratory valve connected to a manifold. The expiratory valve can include a body portion including a feedback port configured to be connected to an air flow generator. The expiratory valve can include a plunger at least partially disposed in the body portion. The expiratory valve can include a pressurizing chamber positioned between an end of the plunger and an end of the expiratory valve. The pressurizing chamber can be configured to receive air from the air flow generator through the feedback port.

A system for treating a patient suffering from obstructive sleep apnea may include a mask, a portable air flow generator configured to generate air flow at a relatively low flow rate, and a tube connecting the air flow generator and the mask such that air flow from the generator passes through an air flow generator valve on the mask. The mask may include a contact surface for forming a seal between the mask and the patient's face such that the mask surrounds the patient's nostrils, an expiration valve that opens during expiration, and an air flow generator valve that opens during inspiration. In some embodiments, the mask may further include an inspiration valve that opens during inspiration to allow air from outside the system to enter the mask.

A device for supporting a flexible hose extending between an individual and a stationary base unit nearby, is disclosed. The support device flexibly supports the hose generally above the individual yet readily accommodates movement by the individual while maintaining communication between the individual and the base unit through the hose. The device is particularly adapted for use by individuals suffering from sleep apnea and who use units to assist in breathing while sleeping or resting. The device can be easily placed into one or more configurations so that it is hidden from view or transportable.

The invention discloses a method and device for detection of a sleep apnea fragment based on unsupervised feature learning. The method includes the steps: collecting sleeping electrocardiosignals (ECG), performing analog-digital conversion on the ECG signals so as to obtain electrocardio digital signals, performing segmentation on the electrocardio digital signals according to minutes so as to obtain ECG segments, extracting a RR interphase sequence for correction according to the ECG segments, performing cubic spline interpolation and fast Fourier transform so as to obtain a frequency domainsequence, making a train set, constructing a stack-type sparse self-coding model, adopting an unlabeled data set to perform pre-training of a sparse self-encoder, performing unsupervised learning andfeature extraction on the frequency domain sequence, performing fine tuning on the stack-type sparse self-coding model by using a labeled train set, constructing a Softmax-hidden markov and time-dependent-cost-sensitive classification model, using the sparse self-coding model to obtain features and corresponding labels in the labeled train set, and training the Softmax-hidden markov and time-dependent-cost-sensitive classification model by using the features and corresponding labels in the labeled train set so as to obtain a sleep apnea classification model.

The invention provides an adhesive coated anti-snoring device that attaches to a specific area of the neck. The device exerts a predetermined force on this area of the neck, causing this area of the neck to expand outward from its normal position. This expansion opens a blockage in the throat of a sleeping person, thereby eliminating snoring and helping some people with obstructive sleep apnea.

The invention discloses a device used for treating sleep apnea and consisting of a top denture and a bottom denture and an application method of the device. Each of the dentures is suitable for keeping the corresponding upper teeth and lower teeth; and the bottom denture is provided with two flanges upwardly extending from the roughly flat side of the denture at the bottom, and the other side of the denture is propped against teeth. Therefore, during wearing of the device, the flanges extend to the top denture. A corresponding flat area is arranged on each side of the top denture, and the flat areas can be cut in the planes on the outer sides (relative to teeth) of the dentures. The flanges are accordingly propped against the flat parts on the outer sides of the dentures to push the bottom denture and push the lower teeth and the tongue forwards. When a wearer wears the dentures in sleep, respiratory obstruction caused by the tongue in sleep is avoided.
