Oral airway devices comprising a tubal body formed by a wall which has a length between a distal end and a proximal end, the tubal body being curved into an arch, the wall having two hollow channels which are passages in the tubal body, a first channel and a second channel, wherein the two channels are laterally aligned, wherein the first channel is the passage located peripherally in the tubal body and wherein the second channel is the passage located centrally or substantially centrally in the tubal body and is compatible with a camera insertable and removable from the second channel; and wherein the tubal body does not comprise an endotracheal tube (ETT) lumen.

A surgical system includes an endotracheal system and intubation system. The intubation system includes an introducer rod and intubation instrument. The intubation instrument includes: an esophageal tube, intubation tube, endoscopic camera tube, and balloon located distally beyond a distal end of the intubation tube. The introducer rod is insertable through the intubation tube to a position where an endoscopic camera in the endoscopic camera tube has a line of sight to a distal end of the introducer rod. The balloon is movable from a deflated condition to an inflated condition in which the balloon fully occludes the esophageal opening to block advancement of the introducer rod into the esophagus and urge the introducer rod into the trachea. The intubation tube is removable from the patient leaving behind the introducer rod, such that the introducer rod is guides an endotracheal tube of the endotracheal system into the patient's trachea.

The self-inflating bag control system is characterized in that it comprises a bag controlling valve which is connected to at least two gas pumps and at least one gas parameter sensor via the gas distribution tubes. It comprises at least one gas pressing device connected to the valve via a gas parameter sensor via gas flow tubes. A control unit with a control panel is connected to the system through a gas sensor, which includes a sub-unit for setting the parameters of the gas flowing into the self-expanding bag, a measuring and analyzing the parameters of the gas flowing in the system by measuring the pressure and volume of the gas from the as parameters sensor, and a warn-alarm sub-unit, which generates a warning and/or alarm signal on the basis of the gas parameters read from the measurement and analysis subunit.

A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.

The disclosure relates to an airway maintenance device, such as an endotracheal tube, tracheostomy tube, or supraglottic airway device, and in particular to an airway maintenance device having a sensor for measuring capillary blood flow and/or pressure. The device includes an airway maintenance device with an airway lumen having a proximal end and a distal end, a distal end portion incorporating an optical sensor configured to measure capillary blood flow in tissue surrounding the distal end when in position within a patient's airway. The optical sensor may include a portion of an optical fibre extending to the distal end portion along the lumen.

A larynx mask is provided that comprises a dorsal cover plate with an inflatable cuff integrally formed thereon and a tube connecting connector having an insertion section for connecting to an insertion tube. Two separate lumens are provided in the region of the insertion section, these being the esophageal lumen and a respiration lumen. These two lumens are separated from each other by a separating and supporting, wall. The separating and supporting wall extends from the insertion section to the tip of the larynx mask. While the esophageal lumen opens into an esophageal outlet at the proximal end of the mask, the respiration lumen opens in the ventral direction and is closed in the proximal direction close to the tip of the mask. Such a larynx mask is produced in one piece by way of injection of molding and is reinforced by the separating or supporting wall to prevent kinking.

A method of indicating an oxygen desaturation period has been initiated includes detecting an oxygen mask configured to supply oxygen to a patient to saturate the patient, detecting a removal of the oxygen mask from the patient to stop saturation of the patient, initiating a desaturation timer in response the removal of the oxygen mask from the patient, and operating an image display device to display a first running time on a screen of the image display device indicating a desaturation time elapsed from a time of the removal of the mask.

Methods for cerebral cooling are described. Cooling assemblies include elongate tubular members, a reservoir containing a pressurized fluid, and a manifold connecting the reservoir and elongate tubular members. After insertion of the elongate tubular members into the patient's nostrils, a pressurized fluid is delivered onto a surface of the patient's nasal cavity through a plurality of ports in the elongate tubular members. The delivery of the fluid causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis.

Devices, systems, and methods of facilitating airway management with reduced risk of release of droplets and aerosolized pathogens from the lungs of a patient are disclosed, including a bronchoscope adapter for an endotracheal tube, an endotracheal tube with integral bronchoscope adapter, an endotracheal intubation mask system, a laryngeal mask airway-specific mask system, and a quick-seal laryngeal mask airway-specific mask system.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.
