In one aspect, this disclosure relates to a stylet having a channel for housing a bougie, drug delivery and suction. In another aspect, the present disclosure relates to a system comprising the stylet and bougie device for guided placement of an endotracheal tube in the trachea. The disclosure further relates to intubation methods in which placement of an endotracheal tube is guided with the stylet/bougie device according to this disclosure.

The present disclosure pertains to a system configured to enhance deep sleep in a subject during positive airway pressure therapy. A pressure generator is configured to generate a pressurized flow of breathable gas for delivery to an airway of the subject. Sensors are configured to generate output signals conveying information related to breathing of the subject. One or more hardware processors are configured to cause the pressure generator to generate the pressurized flow of breathable gas in accordance with a positive airway pressure therapy regime based on the information in the output signals; determine sleep stages of the subject based on the information in the output signals; and responsive to the sleep stages indicating the subject is in deep sleep, cause the pressure generator to adjust the pressurized flow of breathable gas to deliver a stimulus to the subject, the stimulus configured to enhance deep sleep in the subject.

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 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.

A device and a method for creating and/or maintaining an obstruction free upper respiratory passages. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.

Technologies are disclosed for an intubation positioning device that may be configured to selectively adjust a head, neck, and/or an upper back of a patient lying on a surgical table. The device may comprise a body that may have a top, a bottom, a superior end relative to the neck, and/or an inferior end relative to the neck. The body may include an outer casing that permits expansion and contraction of the body in at least a vertical direction, perhaps via at least two inflatable chambers disposed in the body. At least a part of the superior end may be sized or shaped to receive the head of the patient. The device may include a controller configured to selectively permit entrance of a fluid into the first inflatable chamber and/or the second inflatable chamber that may be independently transitioned between an inflated shape and a deflated shape.

A unitary adapter includes a body having a small-bore connector formed at a first end and an opening formed at a second having a larger circumference than the small-bore connector. The small-bore connector couples the body and a operating laryngoscope. The larger opening end couples the body and a breathing circuit. The unitary adapter connects the breathing circuit to the operating laryngoscope.
