An airway management device has a body (6) including an external shell moulded from a polypropylene copolymer (PP) blended with a thermoplastic elastomer (TPE) of styrene-ethylene/butylene-styrene (SEBS), the external shell extending from a proximal opening to a distal tip of the body (6), the external shell having a curved portion (35) and a linear portion (37). Methods of manufacturing are also disclosed.

The present disclosure relates to a method for automatic evaluation of a filling volume of an oesophageal balloon catheter (26) inserted into a mechanically ventilated patient (3). The method comprises obtaining (S3-S4) samples of an airway pressure, P.sub.aw, and an oesophageal pressure, P.sub.es, of the patient during an occlusion period in which respiration of the patient is prevented, evaluating (S5) the filling volume of the oesophageal balloon catheter by determining a ratio, ΔP.sub.es/ΔP.sub.aw, between P.sub.es and P.sub.aw from a regression analysis of the P.sub.es and P.sub.aw samples, and communicating (S6) a result of the evaluation to a user.

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.

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.

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distal ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

The present disclosure relates to airway devices. It is applicable to supraglottic devices including laryngeal airway devices and to their methods of manufacture. The present disclosure is particularly applicable to laryngeal airway devices for human and veterinary use. The device includes an airway tube having a distal end and a proximal end, the distal end of the airway tube is provided with a pre-formed and non-inflatable peri-pharyngeal bowl. The peri-pharyngeal bowl includes a posterior bowl portion having a back dorsal portion and a side wall extending around and depending from the periphery of the back dorsal portion to define an internal space, and further includes a resiliently deformable flange extending laterally from the side wall of the back dorsal portion which defines an extended internal space, the resiliently deformable flange has inner and outer surfaces that extend to a circumferential edge.

A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.

The invention is an endotracheal intubation for preventing injury to throat, vocal cords and trachea. The endotracheal intubation comprises a hollow intubation body with a variable outer diameter. The hollow intubation body comprises a front end and a tail end, an inner intubation wall and an outer intubation wall, and having a retracted state with a smaller outer diameter and an expanded state with a larger outer diameter. When the endotracheal intubation inserted into a patient’s trachea needs to be replaced, as long as the hollow intubation body of the new endotracheal intubation is in the retracted state, it can be inserted into the hollow intubation body to be replaced, and when reaching the position, the hollow intubation body to be replaced is withdrawn, and finally the new hollow intubation body is changed into the expanded state, i.e. the replacement operation of the endotracheal intubation is completed.

A dual suction tube is provided that includes a lower section, an upper section, and a transitional zone. The lower section includes at least one eyelet disposed at a distal end of the lower section. The upper section includes at least one port configured to be connected to a vacuum source. The transitional zone is between the lower section and the upper section, and has a first cross-sectional area at a proximal end of the transitional zone and a second cross-sectional area at a distal end of the transitional zone. The first cross-sectional area is greater than the second cross-sectional area.

The invention provides a device for inserting an infraglottic airway or an imaging device into a patient, the device comprising an open channel which is curved along its length, a first end of the device comprising a handle portion and a second end of the device being configured, in use, to extend to the opening of the patient's trachea. The invention also provides an infraglottic airway device comprising an endotracheal tube and two annular inflatable cuffs, wherein each cuff is provided with an inflation line through which the cuffs can be inflated or deflated.
