A laryngeal mask including a rigid hollow tube essentially in the form of a J, and which has a lengthwise opening along its entire length, and a flexible tube, also essentially in the form of a J, configured to be housed in the lengthwise opening of the rigid hollow tube, and which can be separated from it. This provides a configuration for a laryngeal mask that can change from having rigid properties to flexible ones at the doctor's will, without the need to interrupt the patient's supply of oxygen at any time.

A laryngeal mask for use in a patient includes an airway tube having an inner lumen and a distal end; and a mask portion connected at a proximal end thereof to the distal end of the airway tube and having a distal tip opposite the proximal end. The mask portion includes an inflatable cuff including an anterior cuff surface configured to contact the patient's tissue when the inflatable cuff is inflated; and a wedge portion including a stabilization surface and two walls connected to the inflatable cuff and extending therefrom toward the stabilization surface, the stabilization surface extending from the distal tip of the mask portion toward the distal end of the airway tube at a wedge angle of between about 12 and 30 degrees, the wedge angle formed between the stabilization surface and the anterior cuff surface when the inflatable mask is inflated, whereby the stabilization surface is transversely and longitudinally substantially flat to stabilize the laryngeal mask in use. The laryngeal mask has a gastric tube with a varying inner tube diameter.

Apparatus (10,226,326) for condensing water from respiratory gases, comprising a heat exchange component (20,234,334) having an inlet (22,228,328), an outlet (24,228,230) and a condensation chamber, the inlet and outlet (22,24,228,230,328,330) being connectable to a breathing system, such that respiratory gases are conveyed through the condensation chamber, in use, and a base unit (30,232,332) adapted to aid removal of heat from the walls of the heat exchange component (20,234,334), wherein the heat exchange component (20,234,334) is releasably engageable with the base unit (30,232,332), such that the heat exchange component (20,234,334) is replaceable.

A laryngeal tube with a self-sealing valve, a pilot balloon, a cuff inflation line, a suction port, and a radiopaque cover. The laryngeal tube further includes a proximal cuff for securing a pharyngal area of a patient and a distal cuff for preventing oxygen escape into a stomach of the patient. The laryngeal tube further includes a suction lumen configured to reduce a risk of aspiration in a trachea of the patient and a pharyngal lumen configured to provide ventilation capacities. The self-sealing valve surrounds a periphery of the cuff inflation line. The suction port, the cuff inflation line, the self-sealing valve, and the pilot balloon all extend through an interior of the radiopaque cover, which connects the pharyngal lumen to the proximal cuff.

A courier airway device includes a tubular structure that defines a central channel through which a medical diagnostic or therapeutic device can be inserted. The tubular structure also defines a ventilation duct for providing gases from a controlled ventilation machine to a patient. A cuff is attached to the central channel. Characteristically, the cuff is an inflatable balloon-like ring.

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.

Disclosed is an apparatus for condensing water from respiratory gases. The apparatus has a heat exchange component having an inlet, an outlet and a condensation chamber, the inlet and outlet being connectable to a breathing system, such that respiratory gases are conveyed through the condensation chamber, in use, and a base unit adapted to aid removal of heat from the walls of the heat exchange component. The heat exchange component is releasably engageable with the base unit, such that the heat exchange component is replaceable.

Intubation devices and methods of intubating a patient are provided. The intubation devices include a laryngeal mask airway (LMA) component having a mask portion and a tube portion and an endotracheal tube (ETT) component positioned in the laryngeal mask airway (LMA) component having a translatable and/or rotatable endotracheal tube. The endotracheal tube can be translated and/or rotated by a manipulation rod extending through the laryngeal mask airway (LMA) component and mounted to the endotracheal tube (ETT). The intubation devices may include inflatable cuffs adapted to manipulate the positioning or orientation of the endotracheal tube and/or to seal openings about the endotracheal tubes. Various ports, passages, and conduits are provided to enhance the use and manipulation of the intubation device.

A laryngeal mask includes a housing having a neck part and a head part extending from the neck part. The head part includes a sealing face and an opposing face, the sealing face and the opposing face being connected by an enclosing wall extending upwardly from the sealing face. The sealing face has a peripheral seal for forming a seal around a larynx and having an opening arranged to be positioned over a laryngeal opening. The mask further includes an airway tube positioned within the housing and extending from the neck part to the opening in the peripheral seal. The mask further includes a first drain tube extending from the neck part to an aperture located in a distal tip of the head part, and a second drain tube extending from the neck part to a position within the head part that is proximal to the distal tip.

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.
