In one aspect, this disclosure relates to a stylet having a channel for housing a bougie, drug delivery and suction. In another aspect, the present disclosure relates to a system comprising the stylet and bougie device for guided placement of an endotracheal tube in the trachea. The disclosure further relates to intubation methods in which placement of an endotracheal tube is guided with the stylet/bougie device according to this disclosure.

A medical apparatus for insertion into an internal passage of a subject is provided having a body portion defining an exterior surface; one or more sensors disposed on the exterior surface of the body portion, the one or more sensors providing an insertion force profile representing the force exerted by the internal passage on the sensors during insertion of the body portion; and a processor and non-volatile storage associated therewith, the processor configured to execute software to compare the insertion force profile provided by the sensors with two or more training force profiles stored on the storage, and classify the insertion force profile provided by the sensors as corresponding to at least one of the training force profiles.

A method of method of high flow oxygen therapy (HFOT) and carbon dioxide (CO.sub.2) monitoring includes delivering high flow oxygen therapy (HFOT) via a central lumen of a nasal cannula, the nasal cannula comprising a proximal end, a distal end positioned within a pharynx region of a patient's airway, and the central lumen and a sampling lumen formed within a wall of the nasal cannula. The method also includes receiving sampled exhaled breath of the patient via the sampling lumen at a CO.sub.2 monitor, wherein the sampling lumen is configured to sample the exhaled breath at the pharynx region through the CO2-permeable membrane and direct the sampled exhaled breath to a CO.sub.2 monitor fluidly coupled to the sampling lumen and determining a level of CO.sub.2 in the exhaled breath using the CO.sub.2 monitor.

A suction-target guide pipe that is connected to a suction tube of a suction device includes a guide-pipe main body that includes a connecting portion to be connected to the suction tube, a lid that is provided at an end of the guide-pipe main body and that has an outer peripheral surface and an opening on a distal end side, the outer peripheral surface being formed of a tapered surface whose diameter increases from the distal end to a proximal end, and an end cap that is movable so as to open and close the opening of the lid via a connection cord that is connected to an end of the lid. These features are provided to more easily achieve minimally invasive suctioning of a suction target.

An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is disposed distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached at an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.

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.

An airway stabilization system including an airway device and a securing mechanism or faceplate therefor is provided which includes active stabilizing components on both the airway device and the faceplate which prevent clinically significant movement of the airway device with respect to the patient's vocal cords in response to the application of significant forces in any direction to the device, be they longitudinal, torsional/rotational or bending. The system includes an airway device and an attached retention collar which interacts with a securing device/patient to ensure proper airway insertion depth and provide unparalleled strength and stability against movement. The airway stabilization system includes a unique stabilizer readily adapted for use in field situations to releasably engage or release a retention structure on the airway device to facilitate ease of application in all conditions, a twist-off 15 mm connector which allows a secure connection of the 15 mm connector to the airway device while facilitating easy disconnection thereof, and a universal bite block which cooperates with the securing system to prevent oral and/or dental damage and discomfort to the patient when the system is installed.

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.

The present invention provides medical devices comprising at least one visualization device sealed to, attached to or otherwise combined with at least one of the following second devices: an oral airway, ventilating mask, urinary catheter, trocar, a tool tube, and a medical glove. The present invention also provides methods for rapid and accurate placement of a medical device in a patient and continuous real time monitoring, including a remote monitoring, of the patient after the placement.

The present invention provides laryngeal mask airway for sedative endoscopy, including: a laryngeal mask/endoscope guide unit which is positioned in a larynx region inlet through a patient's oral cavity and guides a supply of air to a respiratory tract and insertion of an endoscope into an esophagus; an airway unit which is connected to the laryngeal mask/endoscope guide unit to supply air to the patient's respiratory tract and to allow the patient's breathing state to be visually checked; a mouthpiece unit which is installed outside the airway unit and fixed between the patient's teeth to protect a tube of the airway and an endoscopic probe inserted into the oral cavity; and an indication end which is positioned at a portion of the mouthpiece positioned outside the oral cavity and moves in accordance with the patient's breathing state to allow spontaneous breathing to be checked, such that the patient's safe airway may be ensured, the insertion of the endoscopic probe and the procedure may be smoothly performed, the patient's spontaneous breathing is easily checked even in a dark space, and as a result, the endoscopy may be safely performed.
