The present disclosure describes an endotracheal tube for a child, the tube having a balloon mounted near the distal end of the tube. The tube has a ventilation lumen and an inflation line used to inflate the balloon. The balloon is mounted to the tube at a lower mounting point and an upper mounting point. The upper mounting point is above the level of the vocal cords. The balloon has a lower and upper diameter when inflated, and the upper diameter is from 1.1 to 1.5 times larger than the outer diameter of the tube.

The present invention relates to a patient-contacting element (10) or a patient interface (12) including such a patient-contacting element (10) wherein the required minimum pressure for sealing may be realized for all different values of CPAP pressure. In particular, the present invention relates to a patient-contacting element (10) for a patient interface (12) for delivering a flow of gas to a user (20), said patient-contacting element (10) being configured to provide a substantially air-tight seal with the user's skin during use and comprises an inlet (14) for receiving at least part of the flow of gas (40), at least one gas-permeable element (16) that is disposed within the patient-contacting element (10) and arranged in fluidic communication with the inlet (14), and a first layer (18) of an air-tight material that is arranged between the at least one gas-permeable element (16) and an inner space (52) of the patient-contacting element (10) for receiving a nose and/or a mouth of the user (50), wherein the air-tight material has at least one opening (20) therein.

A lung isolation system configured for selective isolation and ventilation of the lung in conjunction with a standard endotracheal tube. The system includes an expandable bronchial isolation tube comprising a collapsible nitinol frame, a bifurcated adapter, and a steerable optical stylet.

A system includes an endotracheal tube having a plurality of electrodes, wherein the electrodes include at least one stimulating electrode configured to stimulate tissue of a patient and at least one monitoring electrode configured to monitor at least one nerve of a patient. The system includes a nerve integrity monitor device configured to send a stimulation signal to the at least one stimulating electrode to evoke a reflex response, and configured to receive a monitoring signal from the at least one monitoring electrode.

A tracheal tube has a high-volume/low-pressure sealing cuff (10, 201, 310, 510, 610, 710, 810) with an outer surface provided with surface formations (211, 311, 511, 611, 711, 811) adapted to reduce the flow of secretions past the cuff. The formations could be in the form of an array of dimples (211) or a pattern of linear ridges or channels (611 or 711). Alternatively, the surface formations, could be a pattern of intersecting linear projections (311, 312, 313) or grooves (511). Instead the surface formations could be provided by a rough texture (811) on the outer wall surface.

A device for maintaining an airway in a patient includes a mask having a portion that forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx, includes an airway tube connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The mask includes a proximal portion adapted to collapse or compress so that a proximal ventral part of the mask can move relatively towards a dorsal part of the mask during insertion of the mask. This facilitates insertion of the mask into the patient.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

A tracheal device for the assisted respiration of a patient includes a first tube having a proximal end to be arranged protruding from the mouth of the patient and connectable to a device for assisted respiration, a distal end adapted to cover an orifice, and a first sealing element coupled externally to the first tube. The tracheal device also includes a second tube having a distal end adapted to cover the orifice, a second sealing element coupled externally to the second tube, and a flexible and collapsible service duct stably coupled to the first tube and the second tube to allow the service duct and the first and the second tubes to be arranged in two configurations.

Embodiments of the invention relate to a ventilation device comprising: a. a ventilation tube having proximal and distal ends; and b. an inflatable cuff having a proximal bulge portion and a distal neck portion disposed distal to the bulge portion, the inflatable cuff being mounted around the ventilation tube to define proximal and distal cuff attachment locations which are both fixed on an outer surface of the ventilation tube.

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.
