Disclosed herein are endotracheal tubes that have external baffles near the distal end of the tube to reduce unwanted migration of the tube relative to the trachea and to help prevent materials from passing between the outside of the tube and the tracheal walls. The baffles can be made of soft flexible material that conforms to and seals against the trachea. The baffles can be angled proximally or distally, or both. The baffles can be tapered in thickness and can vary in radial length. Some embodiments can include a supraglottic umbrella. Some embodiments can include an axially expandable portion along the tube. Some embodiments can include a loading tube that helps set the deflection orientation of the baffles within the trachea.

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a mechanically-actuated endotracheal tube cleaning device is configured to removably receive a visualization member to provide cleaning of the endotracheal tube under direct visualization.

An airway device for human or animal use comprising an airway tube having a distal end and a proximal end, the distal end of which is surrounded by a laryngeal cuff, adapted to fit anatomically over the laryngeal structure of a patient, wherein the device optionally further comprises a buccal cavity stabilizer located on or around the airway tube between the laryngeal cuff and the proximal end of the tube, said buccal cavity stabilizer being adapted to nest with the anterior aspect of the patient's tongue, the size, shape and configuration of the buccal stabilizer being adapted to prevent rotational or side-to-side movement of the airway device in use.

Glottis Mask Airway (GMA)an aperture of larynx sealed airway for human ventilation includes a main airway; a non-inflatable cuff at the distal end of the main airway; the shape of the cuff is matched the shape of aperture of larynx perfectly. There is a sealing ring in the device to seal the intersection angle between the aperture of larynx and the wall of pharynx to prevent leakage during the ventilation. There is an epiglottis holder within the cuff where corresponding the epiglottis to prevent the epiglottis falls into the main airway cause the airway block. Plus there are 1) C-channel for gastric tube insertion; 2) at the proximal end of the main airway an openside airway is able to push ETT to the proper position at once; 3) a tongue base rest as the device stabilizer to stabilize the device in using.

An intubating neonatal laryngeal mask airway includes an elongated body having a palate side and a lingual side. A cuff is coupled to an elongated body opposite a distal end of the elongated body. The cuff includes a concavity positioned opposite the palate side of the elongated body and between a guide sleeve and an esophageal plug. At least one ventilation lumen traverses the elongated body from the distal end to the cuff. The at least one ventilation lumen is in fluid communication with at least one ventilation port. A guide channel is longitudinally positioned on the lingual side of the elongated body. The guide channel is operatively aligned to a guide sleeve. An imaging device port is positioned within the concavity.

A treatment system delivers a breathing gas and frozen ice or other particles (FSP) to a bronchus of a lung of a patient in order to induce hypothermia. The breathing gas and the FSP are usually delivered through separate lumens. Clogging of an FSP lumen can be inhibited by heating and/or cooling of the lumen. The temperature of exhaled gases or a body temperature may be measured, and a controller can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured temperature.

A conduit arrangement (1) comprises distal and proximal ends (2,3) and two tubular lumens (10,11). Each tubular lumen (10,11) comprises a longitudinal axis extending between the distal and proximal ends (2,3) and independently permits fluid communication between the distal and proximal ends (2,3). The interior of each of the two tubular lumens is made from a biocompatible material. At least a portion of at least one tubular lumen (10, 11) is capable of imparting helical flow on fluid passing through said portion of the tubular lumen (10,11). The helical flow is spiral laminar flow.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

In one embodiment, a mechanically-actuated endotracheal tube cleaning device is configured to removably receive a visualization member to provide cleaning of the endotracheal tube under direct visualization.

Described is a system including an air pressure supply arrangement, a sensor and a titration device. The air pressure supply arrangement provides air pressure to a patient's airways. The sensor detects input data corresponding to a patient's breathing patterns of a plurality of breaths. The titration device receives and analyzes the input data to determine existence of breathing disorder and corresponding characteristics. The titration device generates output data for adjusting the air pressure supplied to the patient as a function of an index of abnormal respiratory events included in the input data.
