Medical devices which are compatible with a camera for ventilating, intubating, and extubating a patient under continuous visualization. Methods for ventilating, intubating and extubating a patient with the medical devices.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods to guide delivery devices and instruments. Exemplary instrument guides, including for endoscopes as delivery devices for cryogen delivery catheters and to guide cryogen decompression tubes as instruments, and methods for use of such instrument guides for use in body lumens at treatment sites, are disclosed.

Novel airway devices and methods address complications of ventilating a patient with a mask; placing an endotracheal tube in an awake patient; and need for a bite block during flexible bronchoscopy and gastroscopy. The airway device features notches for engaging maxillary and mandibular teeth in a manner protracting the patient's mandible relative to the maxilla to open up the airway. This way, an open airway is easily maintained simply by holding the jaw closed against the device with the same hand used to operate a bag ventilator. A longitudinal channel in the device features a downwardly curved end wall for improved guidance of the endoscope into position. The channel is open sided at the top or bottom to allow rolling of the airway device off the endoscope into an offset position serving as a protective bite block and allowing feeding of the endotracheal tube along the endoscope.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient includes 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 respiratory gas is controlled by a microprocessor, a mixing area for mixing a first gas and a second gas in the respiratory gas flow pathway, a humidification area downstream of the mixing area and configured for humidifying respiratory gas in the respiratory gas flow pathway, and a heated delivery conduit for minimizing condensation of humidified respiratory gas.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

A respiratory assembly is provided. The assembly includes a base engaged with at least one connector and in fluid communication with a hose or fluid source for allowing the gaseous flowthrough between the at least one connector, the base and the hose or fluid source. The assembly further includes a pair of sockets engaged with the at least one connector, and a pair of posts, each post selectively engageable with at least one of the pair of sockets. Each post includes a flange that defines an opening therethrough, the openings in fluid communication with each corresponding socket of the pair of sockets. Each post further includes an adhesive adhered to each flange and configured for sealably engaging a patient's nare.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.

Example embodiments of the present invention provide a multi-function oral appliance, comprising an elastomeric polymer, a hard non-elastic polymer, or a combination of the two fused together; formed using 3D printing or vacuum-forming; configured to engage all or part of the bottom and top teeth such that the lower jaw is advanced, e.g., 8 mm, anterior to its habitual resting position and opened, e.g., 8 mm, from its habitual resting position when the appliance is applied; and configured such that, e.g., 90%, or more, of airflow through the mouth is blocked by the appliance. In some embodiments, the appliance is configured to include gel-wells in the interior of the appliance.

An oxygen mask may include a convex shell having an upper portion and a lower portion and defining a chamber, a rim at least partially around the chamber, a nasal access port in the upper portion, and an oral access port in the lower portion. The nasal access port that is penetratable and/or puncturable to provide access to the chamber, and the oral access port may include a bite block defining a lumen and a valve in the lumen. The oxygen mask may include an inlet into the chamber, an outlet from the chamber, and a sampling port in communication with the chamber. The oxygen mask may include at least one fold or crease configured to allow the bite block to tilt relative to the horizontal axis and/or to translate along the vertical axis.

Oral appliances that may include a supporting shell member having concave geometry for receiving at least a portion of a dental arch of a wearer into the concave geometry; and, a tongue guide member extending from said supporting shell member and into contact with an underside of a tongue of said wearer when the portion of the dental arch is received into the concave geometry. This oral appliance may be utilized in methods for treating various sleep and breathing disorders (“SBD”), for treating sleep apnea, treating airway obstruction, for upper and/or lower jaw reshaping, for airway reshaping, for mandibular advancement, for tongue-retaining, and for providing myofunctional therapy to encourage and help train the tongue to have the proper tongue posture for nasal breathing and discourage mouth breathing.
