A tube protective sheath or tip is provided for use with a nasal RAE tube in order to minimize bleeding and trauma often associated with passage of a nasal RAE tube through the nasal cavity. The tube protective sheath or tip includes a hollow cylindrical portion that extends and fits snugly over the tube tip of the nasal RAE tube. A tapered, pointed, or rounded distal portion is connected to the hollow cylindrical portion. As the nasal RAE tube is inserted through the patient's nasal cavity, the nasal RAE tube protective sheath or tip spreads the passages gently and smoothly, allowing the nasal RAE tube to follow it into the pharynx. Strings or extensions are attached to the tube protective sheath or tip and are used to prevent loss of the protective tip in the patient's nasal cavity, pharynx, or trachea during the intubation process.

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distill ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

A nasopharyngeal airway device includes an elongate body having a distal end and a proximal end. The elongate body has an outer surface defining one or more open channels extending along the elongate body. The nasopharyngeal airway device includes a securement component securely coupled to the elongate body. The securement component is configured to secure the nasopharyngeal airway device within a nostril of an individual.

Systems, devices, and techniques are described to position a tube in a trachea of a patient as part of an intubation procedure. An intubation system may include a stylet configured to position a tube in the trachea of the patient. The stylet may include an articulating segment and a support segment. The articulating segment may be configured to move between a first position and a second position in response to input received by the support segment. The movement of the articulating segment may be controllable by a caregiver. The intubation system may include a handle configured to receive an input from the caregiver and cause the stylet to move in response to the input.

A medical appliance for the treatment of one or more sleep disorders such as obstructive sleep apnea in a patient, the appliance comprising: a biasing member for inserting behind and exerting a force upon the patient's soft palate or tongue, wherein the biasing member is inserted in a reduced or minimized form and then expanded or firms once in place to exert the force. The appliance may be nasally inserted or be placed through the mouth. In a particular configuration, both the soft palate and tongue are biased to prevent obstruction of the flow of air in the nasopharyngeal airway.

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.

Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia

A retrieval probe for insertion of a bridle into a nasal passageway of a patient is provided. The retrieval probe includes a proximal end and a distal end, a catheter between the proximal end and the distal end, an inner core within a lumen of the catheter, and a magnetic tip disposed at the proximal end. The catheter includes a hollow section disposed between the magnetic portion and a distal end of the stiff inner core. The hollow section may be flexible and can be configured to bend at an angle of about 180 degrees. The system for securing a nasal tube can include a bridle having a magnetic connection portion; and a retrieval probe as described above. The magnetic connection portion of the bridle and the magnetic tip of the retrieval probe can be configured to magnetically couple during a procedure for inserting the bridle in a nasal passageway of a patient.

A securement device for a system for securing a nasal tube is provided. The securement device includes a bridle having a body extending between a first end and a second end. The body has a lobed or star shape. The securement device further includes a magnetic connection portion disposed at the first end of the bridle. A system for securing a nasal tube can include a securement device as described above, and a retrieval probe. The retrieval probe can include a catheter extending between a proximal end and a distal end; and a magnetic tip disposed at the proximal end. The magnetic connection portion of the bridle and the magnetic tip of the retrieval probe can be configured to magnetically couple during a procedure for inserting the bridle in a nasal passageway of a patient.
