An intubation assistance device facilitates insertion of an endotracheal tube or a guide wire into a patient's trachea without requiring a laryngoscope. The device includes a curved flexible tubular member that has a proximal portion having a proximal end, a distal portion having a distal end, and a curved portion between the proximal portion and the distal portion. A lumen extends from the proximal end of the tubular member and terminates in the curved portion of the tubular member. The lumen is sized and shaped so that an endotracheal tube and/or a guide wire is axially moveable through the lumen. A ramp is disposed at a distal end of the lumen, and is angled to facilitate insertion of the endotracheal tube and/or guide wire into the patient's trachea. The distal portion of the tubular member includes an esophageal protrusion that is configured to be inserted in the patient's esophagus.

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.

A system for performing a diagnostic or therapeutic procedure within a subject includes a device having a distal portion configured for insertion within a lumen or duct of the subject, the device including an elongate body having a longitudinal axis, the elongate body comprising a polymeric material and having a proximal end and a distal end, one or more electrically-conductive tracings carried on a first surface of the elongate body and configured to carry a signal, and one or more conductors embedded within the polymeric material and configured to carry a signal.

A temporary esophagus occlusion device for providing temporary occlusion of the esophagus during intubation of a in patient includes a frame configured to transition between a contracted state, in which it can be swallowed by the patient, and an expanded state, wherein in the expanded state, the frame has a maximum outer diameter sufficient to span an inner diameter of the esophagus of the patient. The device also includes a flexible cover connected to and extending over at least a portion of the frame when the frame is in the expanded state to at least partially block flow of fluid and/or solid materials through the esophagus and a guidewire attached to the frame, sized to be swallowed by the patient along with the frame and having a proximal end portion configured to remain external to the patient's body and a distal end connected to the frame.

The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.

There is provided an LMA mask integrated for robotic surgery with ventilation or anesthesia tubes and for receiving the robot head with medical instruments through the mask. The inflatable cuff of the mask surrounds the robot head and ventilation so that the items necessary for surgical procedures are contained within a compact defined area. Increased maneuverability and visibility for the medical professional. Integration of the mask with processes for ventilation or anesthesia by accessories is also provided.

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.

An intubation device assembly includes an intubation device, an optical imaging device attached to the intubation device, an image display device attached to the intubation device, a first position sensor operatively connected to the image display device, a second position sensor operatively connected to the intubation device, and a force sensor operatively connected to the intubation device. A controller operates the image display device to display a video image of the optical imaging device and at least one parameter corresponding to an operation of at least one of the optical imaging device, the first position sensor, the second position sensor, and the force sensor. The controller further determines an orientation of a screen of the image display device according to an operation of the first position sensor. The controller displays the least one parameter in a position on the screen according to the orientation of the screen.

An everting vine robot intubation device capable of automatically and autonomously intubating the trachea and producing a lumen through which artificial ventilation may be conducted. The device includes an everting primary vine robot attached to a mouthpiece and a smaller diameter everting intubation vine robot associated with the primary everting vine robot. The primary vine robot is shaped and sized to extend to the back of a patient's laryngopharynx when fully actuated and the intubation everting vine robot is shaped and sized to extend from the primary vine robot into the patient's trachea when fully actuated.

A pharyngeal tube for establishing an airway within a patient may comprise an elongated hollow tube including a proximal end and a distal end. A mouthpiece may be provided at the proximal end of the tube, and one or more lateral openings may be provided at or near the distal end of the hollow tube. The one or more lateral openings may be formed in a lateral wall of the hollow tube, and a distal tip of the hollow tube is sealed so that air cannot escape the tube from its distal tip. The mouthpiece may form an airtight seal at the patients mouth. The mouthpiece may include an inner flange configured to be positioned between the patients teeth and lips, and an outer flange configured to be positioned on the outside of the patients lips. Some variations of the hollow tube may further include an inner septum that divides the tube into first and second lumens that are connected at the distal end of the tube. Some variations of the hollow tube may provide an inner channel that that extends along the inner surface of the tube. The inner channel may be suitable for receiving a suction catheter, a catheter that can be used as a carbon dioxide or other gas sampling line, or a gastric tube. The suction catheter may be associated with a reservoir in which fluid removed from the hollow tube can be deposited. Some variation may provide a gastric tube that is attached and runs parallel to the pharyngeal tube.
