A laryngeal mask airway (LMA) device includes a backplate, an inflatable balloon, an airway tube, and a non-inflatable skeleton, which extends anteriorly from the backplate, and which is shaped so as to define a skeleton anterior side that has a pre-formed shape. A distal end of an inflation tube is coupled in fluid communication with (i) an interior of the inflatable balloon for supplying air to the inflatable balloon, and (ii) at least a portion of the skeleton anterior side. The inflatable balloon is shaped so as to define an inflatable annular cuff which (a) covers at least a portion of the skeleton anterior side, and (b) has a cuff anterior side that is configured to form a seal around a laryngeal inlet of a patient when the inflatable annular cuff is disposed at an LMA-insertion location within a throat of the patient. Other embodiments are also described.

An airway device for human or animal use includes an airway tube having a first end and a second end, the first end of which is surrounded by a laryngeal cuff configured to fit over the laryngeal inlet of a patient when in situ. The first end of the airway tube is provided with an intubating ramp configured to direct a tube inserted through the airway tube into the laryngeal inlet of the patient when in situ.

A device for visually verifying the proper placement of a tube (e.g. a nasogastric tube) in the body of a neonate, essentially includes an optical fiber and a light source. In combination, the light source is connected to the proximal end of the optical fiber. The light source is then activated to illuminate the optical fiber, and the illuminated optical fiber is advanced through the tube into the body of the neonate. Due to the translucent nature of neonate body tissue, the optical fiber illuminates both the tube and anatomical features of the neonate's internal organs. With this optical capability, a visual determination can be made as to whether the tube has been properly placed.

A laryngeal mask airway device includes a flexible tube set and an annular mask. The flexible tube set has an airway tube and an air guide tube that are juxtaposed. The annular mask has an outer membrane surrounding an outer periphery of one end of the airway tube and an elastic filler disposed inside the outer membrane. The outer membrane is in communication with one end of the air guide tube. When in use, the outer membrane is first squeezed to compress the elastic filler, and then the other end of the air guide tube is closed. The inside of the outer membrane forms a negative pressure to maintain the elastic filler in a small volume, so that one end having the annular mask of the flexible tube set can be placed and positioned in a patient's throat.

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.

An endoscopy device (1) for facilitating use of an endoscope, comprising at least one airway tube (2) and a mask (3) having a distal end (4), a proximal end (5) and a peripheral formation ) capable of conforming to, and fitting within, the actual and potential space behind the larynx of the patient to form a seal around the circumference of the laryngeal inlet, the peripheral formation (6) establishing separation between a laryngeal; chamber side (3a) and a pharyngeal side (3b), the device further comprising a conduit (8) adapted for passage of an endoscope into the oesophagus of a patient when mask (3) is in place, conduit (8) including a distal end for cooperation with the oesophageal sphincter, the conduit having a laryngeal side (8d), a pharyngeal side (8c), a right side (8e) and a left side (8f), and an outlet wherein at the outlet the width between the left side and the right side is smaller than the width of the conduit.

A respiratory mask can be used to provide therapy to patients who also require a nasogastric (NG) tube. The mask seal can include a path that is designed to deform around an NG tube or other without lifting the mask away from a patient's face. The deforming path can help to minimize gaps that form between the patient's face and the mask seal as a result of the tube, thus reducing leaks and improving the efficacy of the treatment.

The present invention provides an inflatable laryngeal mask airway (LMA) for endoscopic diagnosis and treatment. The inflatable LMA for endoscopic diagnosis and treatment includes a cuff and an airway tube. The cuff is fixedly connected to the airway tube. The airway tube includes a ventilation airway, an endoscope channel and an inflation channel which are arranged in parallel. The ventilation inlet, the endoscope inlet and the inflation inlet are located at the end of the airway tube away from the cuff. The cuff includes a base body and an air bag connected to the base body. The inflation outlet is connected to the air bag. The endoscope outlet is connected to a lower surface of the base body and directed to the front side of the base body. The back surface of the endoscope channel is provided with an expansion port extending from the endoscope inlet to the endoscope outlet.

A bi-functional intubating and ventilating supraglottic airway includes a supraglottic bowl defining a distal end, a neck extending outward of the supraglottic bowl and defining a proximal end, and a longitudinally extending intubation conduit formed therethrough. The supraglottic bowl includes a cuff and defines a bowl surface, wherein the intubation conduit extends from the proximal end of the neck to an opening in the bowl surface, and wherein the intubation conduit is configured to have an endotracheal tube inserted therethrough. At least one fluid flow channel is formed longitudinally through a wall of the supraglottic airway, collaterally to the intubation conduit, from the proximal end to the bowl surface within the supraglottic bowl.

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.
