A suction device for use with a medical device may include a suction device body and an extension. The suction device body may include a first lumen positioned therein and including a plurality of holes. The extension may include a second lumen positioned therein and may be coupled to the suction device body and configured to facilitate connection of the suction device body to a suction line. The second lumen may be in communication with/open to the first lumen and the suction line may be adapted for connection to a pump configured to apply a negative pressure to the first and second lumens. The suction device may evacuate fluids and/or solids from a patient in an area proximate to the suction device.

The present disclosure provides generally for a therapeutic oral device for sleep apnea and associated methods for using the device. According to the present disclosure, the device may comprise a hard palate portion, mouth guard portion, and a tongue retainer portion. The hard palate portion may comprise one or more materials. The hard palate portion may also comprise a composite of materials, including but not limited to embedded materials. The mouth guard portion may comprise one or more components that provide stability and maintain the position of the therapeutic oral device within the mouth. The tongue retainer portion may comprise an airway and a predetermined length. A method of use may comprise the utilization of one or more incremental oral devices to overcome a gag reflex. When the oral device is formed from a mold, the mouth guard portion and the hard palate portion may be custom fit to the dimensions of the intended mouth.

Systems and methods for nitric oxide generation are provided. In an embodiment, an NO generation system can include a controller and disposable cartridge that can provide nitric oxide to two different treatments simultaneously. The disposable cartridge has multiple purposes including preparing incoming gases for exposure to the NO generation process, scrubbing exhaust gases for unwanted materials, characterizing the patient inspiratory flow, and removing moisture from sample gases collected. Plasma generation can be done within the cartridge or within the controller. The system has the capability of calibrating NO and NO.sub.2 gas analysis sensors without the use of a calibration gas.

Methods, devices, and systems are disclosed for controlled delivery of a therapy, such as a stimulant, to a mouth of a subject via an oral device positioned in a secured configuration in the mouth. At least one of a tongue position stimulator (TST) and tongue position sensor (TSE) is provided, according to certain aspects. According to another aspect, a stimulus is delivered to the mouth and/or tongue via a mouthpiece secured to the subject's teeth. In another regard, a stimulus is delivered that generates a natural response to eliminate or reduce sleep disorders, such as for example at least one of snoring and obstructive sleep apnea.

A method of method of high flow oxygen therapy (HFOT) and carbon dioxide (CO.sub.2) monitoring includes delivering high flow oxygen therapy (HFOT) via a central lumen of a nasal cannula, the nasal cannula comprising a proximal end, a distal end positioned within a pharynx region of a patient's airway, and the central lumen and a sampling lumen formed within a wall of the nasal cannula. The method also includes receiving sampled exhaled breath of the patient via the sampling lumen at a CO.sub.2 monitor, wherein the sampling lumen is configured to sample the exhaled breath at the pharynx region through the CO2-permeable membrane and direct the sampled exhaled breath to a CO.sub.2 monitor fluidly coupled to the sampling lumen and determining a level of CO.sub.2 in the exhaled breath using the CO.sub.2 monitor.

A suction-target guide pipe that is connected to a suction tube of a suction device includes a guide-pipe main body that includes a connecting portion to be connected to the suction tube, a lid that is provided at an end of the guide-pipe main body and that has an outer peripheral surface and an opening on a distal end side, the outer peripheral surface being formed of a tapered surface whose diameter increases from the distal end to a proximal end, and an end cap that is movable so as to open and close the opening of the lid via a connection cord that is connected to an end of the lid. These features are provided to more easily achieve minimally invasive suctioning of a suction target.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient, the system including a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the pressurized respiratory gas is controlled by a microprocessor.

An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is disposed distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached at an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.
